The height of the building is calculated by representing 1 inch as 8 feet. The final building has a height of 20 feet.
<h3>What is
scaling?</h3>
Scaling is the increase or decrease in the height of an object by a scale factor k.
Given that the scale used is:
1 inch = 8 feet. Hence:
Since the height of the building is 2.5 in, hence:
Height of the final building = 2.5 in * 8 ft per 1 in = 20 feet
The height of the final building is 20 feet.

P≤ 2/3
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
(4, 2) is a solution to the equation
Step-by-step explanation:
if y = 2 and x = 4 add fill them into the equation
3(4) + 4(2) = 20
12 + 8 = 20
20 = 20
this makes the equation true
So yes, (4, 2) is a solution to the equation.
Answer:
Step-by-step explanation:
*Based on the survey which shows 28% of teens regularly watch TV when doing Home work, mathematically, = 0.28 of students watch TV when doing home work
* Suppose there are 379 seventh graders who complete their homework on a particular night.m mathematically, using the data of the survey that 28% of teens (seventh grader) watch TV while doing homework.
Using the survey analysis to compute the number of teens on this night that would be doing homework and also watching TV will be;
0.28* 379 =106.12.
The above computation explains that a possible number of 106 teens would be watching TV and also doing there home work, i.e in more sense 28% of this 379 teens doing homework and watching TV is 106
Answer:
-3y+15
Step-by-step explanation:
2y - 5(y - 3)
To simplify, the first step is to distribute the -5
2y - 5y +15
Combine like terms
-3y+15
