## Tina can paint a room 1.5 times faster than Joey can. If they work together, they can paint a room in 6 hours. How long would it take the slower person working alone to paint the room?

[ad_1]

To answer this problem, let us define that:

x = amount of time Joey can paint a room in hours

1.5 x = amount of time Tina can paint a room in hours

Each person can complete 1 job in the specified amount of
time.

1 job / x hours = rate of Joey

1job / 1.5 x hours = rate of Tina

By adding the two, they can paint the room (1 job) in 6
hours. Therefore:

(1 / x) + (1 / 1.5 x) = 1 / 6

Multiplying whole equation with 6 (x) (1.5 x):

6 (1.5 x) + 6 x = x (1.5 x)

9 x + 6 x = 1.5 x^2

Dividing both sides with x:

15 = 1.5 x

x = 10 hours

Therefore the time it will take Tina, the slower person, is
1.5x = 15 hours

ANSWER: 15 hours

## Read the excerpts from different sections “The Scarlet Ibis.” Although Doodle learned to crawl, he showed no signs of walking, but he wasn’t idle. He talked so much that we all quit listening to what he said. It was about this time that Daddy built him a go-cart and I had to pull him around. At first I just paraded him up and down the piazza, but then he started crying to be taken out into the yard and it ended up by my having to lug him wherever I went. If I so much as picked up my cap, he’d start crying to go with me and Mama would call from wherever she was, “Take Doodle with you.” *** He’d nod his head, and I’d say, “Well, if you don’t keep trying, you’ll never learn.” Then I’d paint for him a picture of us as old men, white-haired, him with a long white beard and me still pulling him around in the go-cart. This never failed to make him try again. Based on these excerpts, what best describes the symbol of the go-cart within the story? It changes from a symbol of youth to a symbol of old age. It changes from a symbol of success to a symbol of failure. It changes from a symbol of hope to a symbol of desperation. It changes from a symbol of freedom to a symbol of captivity.

## Pat needs to paint an 8 ft x 36 ft rectangular wall. what is the area that she paints?

[ad_1]

Remark: the fence is clearly 420 yards, not 420420.

check the picture

The 2 adjacent rectangles (corrals) form one larger rectangle.

as shown in the figure, let x be the length of the fences perpendicular to the river, then the length of the side opposite to the river will be 420- 2x (yard)

so we can write the following function, which calculates the area A enclosed by the fence, as a function of x.

A(x)=2x(420-2x)

clearly A is a quadratic function, its graph is a parabola. This parabola looks downwards because of the minus of the term -2x

from A(x)=2x(420-2x) we can find that the x intercepts of the parabola are:

one of the roots is x=0

and

420-2x=0,
2x=420
x=210 is the other root.

The x coordinate of the vertex is the midpoint of (0, 210), that is 210/2=105

f(105)=2*105(420-2*105)=210*(420-210=2110*210=44,100 square yard.

the highest point of the parabola is the largest value the function takes, so the maximal area of the fence.

Answer: max area= 44,100 square yard.

## To decorate his bedroom, Jesse spent \$112.65 on new furniture, \$29.75 on paint, and \$48.33 on accessories. About how much did he spend to decorate his bedroom?

[ad_1]

1. If 1 monster = 7.2 aliens and 1 monster = 15.5 oranges. So we can consider it as 7.2 aliens = 15.5 oranges. To find out how many oranges are equal to 1 alien we need to do this:
1 alien = 15.5 oranges/7.2;
1 alien = 2.15 oranges (approximately).

2. We have everything to solve this problem. So in a scaled drawing 1 mm = 150 m. => 1 m = 1/150 mm on the drawing. Then 1 m^2 = (1/150 mm)^2 =>
1 m^2 = 1/22500 mm^2.
So the answer is 1/22500 mm^2.

3. The formula of the length is S=V*t. where V – the speed and t = the time. We already know that V = 60 mph and t = 8 seconds. But the measure of the speed is miles per hour, so we need to convert 8 seconds to hours.
8 seconds = 8/60 minutes = (8/60)/60 hours;
Our solution looks like this:
1) S = 60 mph * (8/60)/60 hours;
2) S = 8/60 miles;
3) S = 0.13 miles;
Answer is 0.13 miles.

4. First let’s find out how many gallons of gas she spent during her trip:
172.5/30 = 5.75 gal;
Now we can find price per gallon:
20,70/5.75 = 3.60\$ per gallon;
So the approximate cost of gas in dollars per gallon is 3.60\$ per gallon.

## Super-yummy soup, inc. wants to paint their entire soup can red, including the top and bottom. if the diameter of the lid is 5 cm, and the height of the can is 9 cm, what is the approximate total surface area that will need to be painted?

[ad_1]

Answer:

Option C – BD=76 cm

Step-by-step explanation:

Given : You are designing a diamond-shaped kite. you know that AD = 44.8 cm, DC = 72 cm, and AC = 84.8 cm.

To find : How long BD should it be?

Solution :

First we draw a rough diagram.

The given sides were AD = 44.8 cm, DC = 72 cm and AC = 84.8 cm.

According to properties of kite

Two disjoint pairs of consecutive sides are congruent.

So, AD=AB=44.8 cm

DC=BC=72 cm

The diagonals are perpendicular.

So, AC ⊥ BD

Let O be the point where diagonal intersect let let the partition be x and y.

AC= AO+OC

AC= …….

Perpendicular bisect the diagonal BD into equal parts let it be z.

BD=BO+OD

BD=z+z

Applying Pythagorean theorem in ΔAOD

where H=AD=44.8 ,P= AO=x , B=OD=z  ………

Applying Pythagorean theorem in ΔCOD

where H=DC=72 ,P= OC=y , B=OD=z  …………

Subtract  and    ……….

Add equation  and , to get values of x and y   Substitute x in   Substitute value of x in equation , to get z     We know, BD=z+z

BD= 38.06+38.06

BD= 76.12

Nearest to whole number BD=76 cm

Therefore, Option c – BD=76 cm is correct.

## It’s very common to have paint thinner in an auto body repair shop. which would be the most effective way of extinguishing a puddle of thinner that catches fire? a. class a extinguisher b. class c extinguisher c. class b extinguisher d. water hose

[ad_1]

Answer:

1) Water has very high specific heat.

2) It expands when it freezes

3) ability to dissolve in ionic substances

4) Water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid.

Explanation:

1) Water molecules due to their high specific heat , undergo relatively less increase in temperature after absorbing heat. So they prevent their adjoining area to experience sharp increase in temperature.

2) Water is an example which expands on freezing. In it , large spaces are left between molecules when it cools. It happens because hydrogen bonds prevent any two molecules to come very close thereby  creating gaps. This gap is filled up when ice melts , which results in overall reduction in volume of water.

3) Uneven distribution of charge results in water molecules becoming polar in nature . A polar substance  can be dissolved in polar solvents only.

4) It is due to property of surface tension. Property  of surface tension results due to molecules of water near the surface experiencing a  net downward  force due to hydrogen bonds . It is due to fewer hydrogen bonds made by them.

## (Informational Response) Review the excerpt above. Answer the following question in a well-developed paragraph. How does the excerpt prepare the reader for the last line? What details and descriptions prepare the reader for the change in tone and mood in that final line? **Be sure to re-state the question in your topic sentence and use specific examples and details from the story to support your answers. Proofread your work before submitting. Chapter I, The Beginning of Things They were not railway children to begin with. I don’t suppose they had ever thought about railways except as a means of getting to Maskelyne and Cook’s, the Pantomime, Zoological Gardens, and Madame Tussaud’s. They were just ordinary suburban children, and they lived with their Father and Mother in an ordinary red-brick-fronted villa, with coloured glass in the front door, a tiled passage that was called a hall, a bath-room with hot and cold water, electric bells, French windows, and a good deal of white paint, and ‘every modern convenience’, as the house-agents say. There were three of them. Roberta was the eldest. Of course, Mothers never have favourites, but if their Mother HAD had a favourite, it might have been Roberta. Next came Peter, who wished to be an Engineer when he grew up; and the youngest was Phyllis, who meant extremely well. Mother did not spend all her time in paying dull calls to dull ladies, and sitting dully at home waiting for dull ladies to pay calls to her. She was almost always there, ready to play with the children, and read to them, and help them to do their home-lessons. Besides this she used to write stories for them while they were at school, and read them aloud after tea, and she always made up funny pieces of poetry for their birthdays and for other great occasions, such as the christening of the new kittens, or the refurnishing of the doll’s house, or the time when they were getting over the mumps. These three lucky children always had everything they needed: pretty clothes, good fires, a lovely nursery with heaps of toys, and a Mother Goose wall-paper. They had a kind and merry nursemaid, and a dog who was called James, and who was their very own. They also had a Father who was just perfect—never cross, never unjust, and always ready for a game—at least, if at any time he was NOT ready, he always had an excellent reason for it, and explained the reason to the children so interestingly and funnily that they felt sure he couldn’t help himself. You will think that they ought to have been very happy. And so they were, but they did not know HOW happy till the pretty life in the Red Villa was over and done with, and they had to live a very different life indeed. The dreadful change came quite suddenly.

Statement A is correct about Sam’s box and whisker plot.

Step-by-step explanation:

We have been given a box plot and we are asked to find out true statement according to the box plot.

Since we know data represented by box plot is divided in four equal parts.

Upon looking at our box plot we can see that our data is symmetric. It’s median is 15, which means half the math assignments have less than 15 problems and half of the math assignments have more than 15 problems.

Interquartile range represents 50% values of data and it is the difference between upper quartile and lower quartile. IQR is not affected by outliers. Upon substituting given values from box plot we get, From IQR we can conclude that half of the assignments contained 15 problems or fewer.Therefore, option A is the correct choice.

Answer with explanation:

1. Scatter plot : In Scatter plot, which consist of two variables, are represented in two dimensional plane through dots.If you join these points along the order in which they are given , you can’t predict whether they are in ascending or descending order.But if you arrange the data in ascending order and then plot it on two dimensional plane, you will get numerical data in ascending order.

2. Line Graph: A line graph is representation of something over a period of time. Suppose an object is not moving uniformly, we plot distance traveled in different interval of time in two dimensional coordinate plane.As Distance traveled is always positive , with increase in time , distance traveled will increase or remain constant , for two duration or period. So, we can say with conformity that Line graph is also one of the simplest way of representation of numerical data in ascending order.

3. Box-and-whisker plot: In Box and whisker plot, when data is arranged in ascending order, then a box is drawn, the upper and lower ends of box are first Quartile and third Quartile Respectively.Median lies inside the box.The spanning of whole box tells about Interquartile range.And the two line segments which are connected from the two ends of box ,one end of segment is lowest value in Data set and Other end of segment is largest observation in the data set.In Box and whisker Plot, Numerical data is also arranged in ascending order.

4. Stem and Leaf Plot: In Stem and Leaf plot, data is splitted into parts, the first digit of number from left is stem and last digit from right is Leaf.

For, example 45,46,47,……

4 is Stem and 5,6,7 are Leaves.

So, the way of representation of numerical data, is simplest in stem and leaf plot.

Option D:Stem- and- Leaf Plot , is simplest method to represent numerical data in ascending order.

Culvert is a tunnel, therefore we can use the volume and area formula of a cylinder.

Circumference is given such as 280 cm and the circumference formula of a circle is C = 2*pi*r

Solving for the radius, we have:
280 = 2*3.14*r
r = 280/2*3.14
r = 44.59 cm

Area of one end:
Area = pi*r²
Area = 3.14 * 44.59²
Area= 6,243.2 cm²

The total area is times two of area since there were two ends in the culvert.
Total area = 6243.2 * 2
