The Number of boys in the class is: 18

 Let's call "g" to the number of girls in the class.

 The problem says that there is "w" fewer boys than girls, so we have:

 g-w=18

 Then, the number of girls in the class  is:

 g=18+w

 Let's call "x" to the total number of studens in the class:

 x=g+18

 When we substitute g=18+w  into x=g+18, we obtain:

 x= (18+w)+18

 The total number of studens in the class is:

 x=w+36

Ava graphs the function h(x) = x2 + 4. Victor graphs the function g(x) = (x + 4)2. Which statements are true regarding the two g
Firlakuza [10]

Answers:

Ava’s graph is a vertical translation of f(x) = x^2.

Ava’s graph moved 4 units from f(x) = x^2 in a positive direction.

Ava’s graph has a y-intercept of 4.

Given:

Ava graphs the function h(x) = x^2 + 4.

Victor graphs the function g(x) = (x + 4)^2

To find y intercept we plug in 0 for x

h(x) = x^2 + 4

h(x) = 0 + 4= 4

So ,Ava’s graph has a y-intercept of 4.

Ava graphs the function h(x) = x^2 + 4

If any number is added at the end then the graph will be shifted up. 4 is added at the end so there will be vertical translation.

Hence , Ava’s graph is a vertical translation of f(x) = x^2. Also Ava moved 4 units up from f(x) = x^2 in a positive y- direction.

Victor graphs the function g(x) = (x + 4)^2

If any number added with x then the graph will be shifted left. the graph will be shifted in negative x direction.

Initially, the ratio of Ed’s toy cars to Pete’s toy cars was 5:2. After Ed gave 30 toy cars to Pete, they each had an equal numb
Burka [1]
So here is the answer. Initially, Ed's toy cars compared to Pete's toy cars was 5:2. So for every 5 cars that Ed has, Pete has 2. Now that Ed gave 30 cars to Pete. So here it goes. The total number of ratio units is 5+2=7, so each will have an equal number if they both have 3.5 ratio units. That is, if Ed transfers to Pete 1.5 ratio units, their car counts will be equal. Thus 1.5 ratio units = 30 cars, or 1 ratio unit = 20 cars. Therefore, this makes <span> 7*20 cars = 140 cars.

Sales tax rate for the above sweater is charged at the rate of 8%

Step-by-step explanation:

Sweater’s cost initially- 28$

Cost of Sweater after 30.24$

Sales tax rate deducted?

Analysing the above-provided details we conclude that an increase in the cost was probably due to the addition of sale tax.

Sales tax charged= Cost of the sweater after charging- initial cost

= 30.24$-28$

=2.24$

Percentage of sales tax charged= (sales tax charged/initial cost) *100

Substituting the values of the sales tax and initial cost in the above-provided equation-

= (2.24/28) *100

=8%

Hence the Sales tax charged at the sweater was 8%
