Answer:
C
Step-by-step explanation:
Answer: Two ways to do this, you can find the area of the rectangle and subtract the 4 triangles or find the area of 4 triangles.
B: 2.25 ft2
Step-by-step explanation:
<u><em>Well, I will first start by finding the area of the top 2 triangles.</em></u>
The equation to a triangle is:
A = 1/2 × l × w
I will replace now the variables:
1/2 × 1 × 0.75 = 0.375
One triangle is 0.375, now I have to find the area of two triangles.
0.375 × 2 = <u>0.75</u>
<u><em>Now I will do the bottom 2 triangles.</em></u>
The equation to a triangle is:
A = 1/2 × l × w
I will replace now the variables:
1/2 × 2 × 0.75 = 0.75
One triangle is 0.75, now I have to find the area of two triangles.
0.75 × 2 = 1.5
<u><em>Now time to add it up.</em></u>
1.5 + 0.75 = 2.25
<u><em>So the final answer is B: 2.25 ft2</em></u>
<u><em>Hope this helps you!</em></u>

Answer:
54minutes
Step-by-step explanation:
Let the time taken to clean up be t
Let the number of people cleaning be n
If the time it takes to clean up after an anniversary party varies inversely as the number of people cleaning then;
t = k/n
k is the constant of proportionality
If 3 people work together to clean, and took them 90 minutes, this means
at t = 90, n=3
Substitute
90 = k/3
k = 3×90
k = 270
To et the time it will take 5people to clean, the will say;
t =k/n
t =270/5
t = 54 minutes
Hence it will take 5 people 54minues to clean
