A chemical or physical change that takes in heat from its surroundings is an exothermic process an explosion an endothermic process a phase change
An object pronoun takes the place of a/an _______ in the object part of a sentence. A. different pronoun B. noun C. verb D. adjective
8x + 6y = 8.50
4x + 4y = 5…..multiply by -2
8x + 6y = 8.50
-8x – 8y = -10 (result of multiplying by -2)
-2y = – 1.50
y = -1.50 / -2
y = 0.75 <=== pens cost 0.75
4x + 4y = 5
4x + 4(0.75) = 5
4x + 3 = 5
4x = 5 – 3
4x = 2
x = 2/4
x = 0.50 <== pencils cost 0.50
The number should be -3. That is because she goes from 0 to three floors bellow, meaning it’s 0-3= -3. The first floor bellow would be -1, the second would be -2, and the third one is -3. It would be different if you counted it as number 1 as they do in some countries, but here it’s -3.
Having a literacy device sheet in hand is important to comprehend if the text passage is a metaphor, simile, hyperbole etc and that help understand complex literacy language in poetry, Shakespearean language, and in eulogy themes.
Hope this helps.
How does Walton describe the stranger he takes onboard
– 2.14 m/s^2
initial velocity , u = 245 m/s
final velocity, v = 230 m/s
time taken , t = 7 second
By use of first equation of motion,
v = u + a t
where, a be the acceleration.
Substitute the values of v, u and t
230 = 245 + a x 7
a = – 2.14 m/s^2
the acceleration is negative, it means the airplane is slowing.
T takes Franklin 14 hours to make a 200-square-foot cement patio. It takes Scott 10 hours to make the same size patio. Which equation can be used to find x, the number of hours it would take Franklin and Scott to make the patio together?
Texting is an increasingly popular means of communication with students at Mystic Falls High School. Students text their friends to make plans, ask questions, and share information. However, texting can also be distracting. It takes students’ attention away from the primary purpose of school: learning. What is the tone of the article? a) meloncholy b) humerous c) respectful d) critical
we know it takes 31 workers to do a car, and 19 to do a motorcycle… so hmmm to make “c” cars, it will then take 31*c workers, or 31c
to make “m” motorcycles, it will then take 19*c or 19c employees
whatever those amounts of workers needed to make both, must be an amount that is 706 or less, thus
31c + 19m ⩽ 706
now…. it takes $7500 to make a car and thus to make “c” cars it will then take 7500* c or 7500c
it takes $4300 for a motorbike, thus to make “m” motorbikes, it will then take 4300*m, or 4300m
whatever those dollar amounts are, must be 84000 or more, since Genghis Motors wants to spend that OR more
7500c + 4300m > 84000
The amount of time it takes to fill a whirlpool tub is inversely proportional to the square of the radius of the pipe used to fill it. If a pipe of radius 2.5 inches can fill the tub in 8 minutes, how long will it take the tub to fill if a pipe of radius 3.5 inches is used? How many inches would the tub fill approximately in minutes?

If it takes 10 men 4 hours to repair a barn, how long will it take 8 men to complete the task?
The centripetal force that keeps the beetle moving in circle is given by:
m is the mass of the beetle
v is the tangential speed of the beetle
r is the distance of the beetle from the center of the record
In this problem, we know the force (F=0.070 N), the mass of the beetle (m=0.023 kg) and the distance from the center (r=0.15 m), therefore we can re-arrange the equation to find the tangential speed:
What is the term for the amount of time it takes 50% of an element to decay
What is the term for the amount of time it takes 50 % of an element to decay?
A golfer takes two putts to get his ball into the hole once he is on the green. the first putt displaces the ball 8 m east, and the second 4.14 m south
Tangential speed is 0.68 m/s
It is given that,
Mass of the beetle, m = 0.023 kg
It is placed at a distance of 0.15 m from the center of record i.e. r = 0.15 m.
If it takes 0.070 n of force to keep the beetle moving in a circle on the record i.e. centripetal force acting on it is, F = 0.070 N
We have to find the tangential speed of the beetle. The formula for centripetal force is given by :
v is tangential speed
v = 0.675 m/s
v = 0.68 m/s
Hence, the correct option for tangential speed is (A).
speed of train=x-30
A loaded moving truck is traveling 30 mph faster than a freight train. in the time it takes the train to travel 135 miles, the truck travels 225 miles. find the speed of the truck.
A loaded moving truck is traveling 30 mph faster than a freight train…
(x-30)=speed of train
the time it takes the train to travel 135 miles, the truck travels 225 miles…
the you multiply on both sides the x values and get…
then you subtract 225x on both sides…
then you divide -90 on both sides…
the speed of the truck is 75mph
i hope this helped give me a thanks and a 5 star rating if it helped! c:
Fg=(G*m₁*m₂)/r₂, where G=6.67*10^-11 m³ kg⁻¹ s⁻² is the gravitational constant, m₁ and m₂ are the masses of the two bodies and r is the distance between those bodies.
Due to the gravitational attraction the pencil and the eraser will attract if we there is no friction on the surface.
m₁=10 g=0.01 kg is the mass of the pencil
m₂=20 g=0.02 kg is the mass of the eraser
r=2.5 cm = 0.025 m
First we calculate the Fg:
To get the velocity v of the pencil:
v²=2as, where a is the acceleration of the pencil and s is the path. In our case s=r so we can write:
a=Fg/m₁= 2.133*10^-9 m/s²
We have the velocity and the acceleration, so we can calculate the time t with the equation:
1 hour has 3600 s so when we divide time t in seconds by 3600 we get time T in hours:
So the time for the pencil and eraser to touch is T=1.3449 hours.
Also time T can be expressed like T= 1h and 20 mins and 41.64 s
The right answer is Transgenic organisms can produce a desired product that may benefit other organisms.
A transgenic organism contains DNA combining stably integrated in all its cells. In other words, the organism, be it a plant, an animal or a microorganism, has a new piece of DNA embedded in it. a chromosome in each of its cells. This “new piece” of DNA usually contains a gene from another organism (plant, animal or other) that has been modified to be expressed in the new organization. A transgenic organism may even possess the DNA of another organism of the same species. The inserted gene can be called the transgene.
Currently, diabetics are treated by injecting insulin from either a healthy human donor or cultures of genetically modified (transgenic) bacteria that secrete the protein.
Let x be the time taken by shoe repairman to repair one pair.
We have been given that his assistant, who takes twice as long to repair a pair of shoes. So time taken by his assistant to repair one pair of shoes would be 2x.
The number of pair of shoes repaired by repairman in one hour would be .
The number of pair of shoes repaired by assistant in one hour would be .
We have been given that together they can fix 16 pairs of shoes in an eight-hour day. We can represent this information in an equation as:
Let us have a common denominator.
Upon cross multiplying our equation we will get,
Therefore, it take 3 hours for the repairman to fix one pair of shoes by himself.
