Melissa will rent a car for the weekend. She can choose one or two plans. The first plant has no initial fee but costs $.80 per mile driven. That’s like a plan has an initial fee of $75 in cost an additional $.38 per mile driven. How many miles with Melissa need to drive for two plants to cost the same? NEED HELP ASAP PLEASE

[ad_1]

If you equal both of the PLANS you will get
$.80x=$75+$.38x
then you subtract .38x on both sides and get
$.42x=$75
once thats done you will divide .42 on both sides leaving the variable x by itself…
and then x=178.57miles
but to break even it would be 179 miles for both of the plans to cost the same

An airplane leaves an airport and flies due west 150 miles and then 170 miles in the direction S 49.17°W. How far is the plane from the airport (round to the nearest mile)? plzzz helpppp

[ad_1]

Answer:

Distance between plane and airport is 134.4 miles.

Step-by-step explanation:

Given : An airplane leaves an airport and flies due west 150 miles and then 170 miles in the direction S 49.17°W.

To find : How far is the plane from the airport.

Solution : Distance from airport to west is 150 miles and then 170 miles in the direction south  and angle form is S 49.17° W

Refer the attached picture for clearance.

Applying law of cosines

c^2=a^2+b^2-2ab Cos(C)

c=sqrt{a^2+b^2-2ab Cos(C)}

where a= 150 miles

b=170 miles

C=   49.17° angle in degree

c = distance between plane from the airport

Put values in the formula,

c=sqrt{a^2+b^2-2ab Cos(C)}

c=sqrt{150^2+170^2-2(150)(170) Cos(49.17^{circ})}

c=sqrt{22500+28900-51000(0.653)}

c=sqrt{51400-33303}

c=sqrt{18057}

c=134.37

Therefore, Distance between plane and airport is 134.4 miles.

1. The answer is “C”.

“Identical twins” who have been raised apart are typically more similar in intelligence level than biological siblings raised together because they have been born with the same genetic code.

Identical twins originate from a single fertilized egg that parts into two. Before it parts, it is either male or female. After it parts, there are either two guys or two females. The two sections of the fertilized egg embed in the uterus and every create one of the twins.  

Identical twins have the equivalent hereditary source. No immediate reason for monozygotic twinning has been resolved; it isn’t innate. Monozygotic twins speak to around 33% all things considered. They may look strikingly comparative, and it might be hard to reveal to them separated.

2. The answer is “A”.

Lawrence Kohlberg felt that one of the only ways individuals will accomplish the objectives in each of his six stages was to participate in “consensus democracy” in small group settings.

Lawrence Kohlberg felt that the best way to support development through these stages was by discourse of good problems and by investment in consensus democracy inside small groups. Consensus democracy was rule by understanding of the gathering, not larger part rule. This would invigorate and widen the reasoning of youngsters and grown-ups, enabling them to advance starting with one phase then onto the next.

3. The answer is “D.  showing a learner how to correct common mistakes”.

The term scaffolding alludes to a procedure in which instructors display or exhibit how to take care of an issue, and afterward venture back, offering support as required. Analyst and instructional architect Jerome Bruner first utilized the term ‘scaffolding’ in this setting, harking back to the 1960s. The hypothesis is that when understudies are given the help they require while discovering some new information, they stand a superior possibility of utilizing that learning freely. Bruner suggests positive association and three methods of portrayal amid educating: activities, pictures, and dialect.

127=7 (mod n) means when 127 is divided by n, the division leaves a remainder of 7.

The statement is equivalent to
120=0 (mod n), meaning that n divides 120.

All divisors of 120 will satisfy the statement because 120 divided by a divisor (factor) will leave a remainder of 0.

Factors of 120 are:
n={1,2,3,4,5,6,8,10,12,15,20,24,30,40,60,120}, |n|=16.
You can count how many such values of n there are, and try to check that each one satisfies 127=7 mod n.

Answer:  The correct option is (C). 10 = square root of the quantity of x minus 8 all squared plus y minus 9 all squared

Step-by-step explanation:  Given that the segment AB has point A located at (8, 9). The distance from A to B is 10 units.

We are to select the correct option that could be used to calculate the coordinates for point B.

Let, (x, y) be the co-ordinates of point B.

According to distance formula, the distance between two points (a, b) and (c, d) is given by

d=sqrt{(c-a)^2+(d-b)^2}.

Therefore, the distance between the points A(8, 9) and B(x, y) is given by

d=sqrt{(x-8)^2+(y-9)^2}.

Since, distance between A and B is 10 units, so

d = 10.

Therefore,

10=sqrt{(x-8)^2+(y-9)^2}.

Thus, the correct statement is

10 = square root of the quantity of x minus 8 all squared plus y minus 9 all squared.

Option (C) is correct.

Answer:  The correct option is (A) dfrac{10}{37}.

Step-by-step explanation:  Given that in a bag of chocolate candy, ten of them are red, 7 are brown, 12 are green, and 9 are blue.

We are to find the probability that we pick a red candy, given that we have already picked a blue candy and have not replaced it.

We have

Probability of picking a blue candy is given by

P_b=dfrac{textup{number of blue candies}}{textup{total number of candies}}\\\Rightarrow P_b=dfrac{9}{10+7+12+9}\\\Rightarrow P=dfrac{9}{38}.

Now, since we have already picked a blue candy and did not replace it, so total number of candies left in the bag = 10+7+12+8 = 37.

There are 10 red candies in the bag,

so the probability of picking a red candy given that we have already picked a blue candy and have not replaced it will be

P_{r/b}=dfrac{textup{number of red candies in the bag}}{textup{total number of candies left in the bag after picking a blue candy}}\\\Rightarrow P_{r/b}=dfrac{10}{37}.

Thus, the required probability is dfrac{10}{37}.

Option (A) is correct.

The answer is:  [A]:  No solution” .
_______________________________________________
Note:  Given:
_______________________________________________
  y = 4x + 8 ;
  y = 4x + 2 ;
_______________________________________________

Since:  “y = y” ;

4x + 8 = 4x + 2 ; which is not true;
______________________________
 4x  +  8  ≠  4x  +  2 ;  since,  “8  ≠ 2” ;

Note:  Suppose:  “4x + 8 = 4x + 2” ; 

→ Subtract “4x” from each side of the equation:

4x + 8 − 4x  = 4x + 2 − 4x ;

to get:
_________________
 ” 8 = 2 ” ;  not true ; since  “8 ≠ 2” ;
______________________________
Also, suppose:
_______________________________
 4x + 8 = 4x + 2 ;

→ Subtract “2” from BOTH SIDES of the equation;

4x + 8 − 2 = 4x + 2 − 2 ;

to get:

4x + 6 = 4x

(Note:  “4x + 0 = 4x” ;  but “4x + 6 ≠ 4x”) l

But even if we have:

4x + 6 = 4x ;

→ Subtract “4x” from EACH side of the equation:

4x + 6 − 4x  = 4x − 4x ;

to get:

   6 = 0 ; which is not true;  “6 ≠ 0” .

The correct answer is:  [A]:  “No solution” .

In given Function,

Coordinates of vertex is ( h , k )

So To, find the vertex of the function.

First we rewrite the function in vertex form that is like equation (1) then we compare them and write the coordinate of the vertex.

For Example,

1. y = 2(x – 2)² + 6 then vertex of the function is ( 2 , 6 )

2. y = -3 ( x + 3 )² – 6

    y = – 3 ( x – (-3) )² + ( -6) then vertex of the function is ( -3 , -6 )

Answer:

The right answer is 20%.

Step-by-step explanation:

To resolve this question, we can use the “rule of three.”

the rule of three tell us=

a————–>b

c————–>d

when we know the values for a,b and c; and we want to know the value of d we can use the next formula:

d=frac{c*b}{a}  

so in this case, we have:

20000———>100% (is 100% cause is the total cost of the car)

16000 ———> x         (we’re going to call x to the value we don’t know, and we want to know; we need to put the same values in the same part, in this example, we placed the costs of the car in the left and the percent in the right.

now using the formule we have:

frac{16000*100}{20000}

frac{1600000}{20000}= 80%

now we know the percent of the 16000, which means that 16000 is 80% of 20000.

the last step to know the decrease is subtract

20000-16000=4000

so

100%-80%=20%

the car’s cost decrease  was 4000 what in percent is 20%
