The answer is 12y+30.
Twice the width would be 10+4y, so the length is 10+4y.
To find the perimeter, we can do 2(5+2y) + 2(10+4y).
That equals 10+4y+20+8y.
Which, equals 12y+30.

Answer:
2 people will take 90 days to complete the same house
Step-by-step explanation:
<u><em>Given:</em></u>
T1 = 30 days
P1 = 6
T2 = x
P2 = 2
This is an inverse proportion because if there are more people, less time will be taken to complete the house and vice versa.
<u><em>So, We'll write it in the order of :</em></u>
=> T1:T2 = P2:P1
=> 30:x = 2:6
<u><em>Writing in fraction form</em></u>
=>
<em>Cross Multiplying</em>
=> 2x = 180
<em>Dividing both sides by 2</em>
=> <u><em>x = 90 days</em></u>
So, <u><em>2 people will take 90 days to complete the same house</em></u>
Answer:
b
Step-by-step explanation:
b
The relative frequency of students who are not seniors at this high school will be 82.96%.
<h3>How to find how much percent 'a' is of 'b'?</h3>
Suppose a number is 'a'
Suppose another number is 'b'
We want to know how much percent of 'b' is 'a'.
Then, it is calculated as:
P = a/b × 100
A local high school has 1,203 students with 367 freshmen, 382 sophomores, 249 juniors, and 205 seniors.
Then the relative frequency of students who are not seniors at this high school will be
P = 998/1203 × 100
P = 0.82959 × 100
P = 82.959%
P ≈ 82.96%
