Answer:
Both expressions equals to 32.
Step-by-step explanation:
You just plug in 5 for each expression: 12+4(5)=32, 4(5+3)=32.
Answer:
12.71in
step explanation:
The Length of an arc given is expressed as;
A = theta/360 * 2πr
10 = 45/360 * 2 * 3.14r
10 = 1/8 * 6.28r
Cross multiply
10 * 8 = 6.28r
80 = 6.28r
r = 80/6.28
r = 12.74in
Hence the radius is 12.71in
Answer:
Answer A: 344 cubic feet
Answer B: Unkown
Step-by-step explanation:
As for the first question, all we have to do is multiply the amount of both boxes by their sizes (7x12 + 13x20) and make sure to add them up to get 344.
Unfortunately, I wasn't able to get the second answer because I don't exactly understand. My sincere apologies
In order to enclose the greatest possible area with the fencing
that he has, Mr. Sanchez should plant the garden inside a circle
with a diameter of 5-ft 1.12-inches. Its area will be 20.37 square feet.
If it absolutely has to be a rectangle, then he will get the greatest
possible area when it's a square. So each side will need to be
4-ft, and the area will be 16 square feet.
I don't know how to prove either of these without calculus.
You'll just have to trust me.
