Answer:
B. 24 yd^2
Step-by-step explanation:
Let A denote the area of the smaller figure:
We can determine the ratio of both lengths and areas as:
3:5 :: A:40
As the areas of figures vary directly with their lengths and widths so the proportion will be direct proportion.
Converting into fractions will give us:
3/5 = A/40
Now we have to find the value of A for the area of smaller figure.
Cross multiplication will give us:
3*40 = 5A
=> 120 = 5A
=> 120/5 = 5A/5
So,
A = 24 yd^2
So, Option B is the correct answer ..

Answer:
Step-by-step explanation:
x/10=7
x=70
A) 130 mins = 2 hours 10 mins or 2 and 1/6 hours... so 2 and 1/6 revolution. and 1 revolution is equal to 2*pi radians
<span>ANSWER: 13/6 (2 and 1/6) * 2*pi = 13.6 radians </span>
<span>b) 8/13.6 = x/(13/6) so x = 0.2715 hours or 16 and 1/3 minutes </span>
<span>c) if the restaurant is 21 meters, the radius is 10.5 meters, and the circumference is 2*pi*r so circumference = 65.97 meters. </span>
<span>2 and 1/6 revolution is going around the circumference 2 and 1/6 times, so simply multiply 65.97 by 13/6 </span>
<span>ANSWER: about 143 meters</span>
