Answer:
Step-by-step explanation:
item 4 Find the perimeter of the window. Round your answer to the nearest tenth. 90 cm
You did not state the diameter or radius of the window
so, i will use 90cm as the diameter of the window
First, I'd calculate the half circumference of the window.
The formula for circumference is 
,
Half of it would just be 
Since our diameter is 90 cm, our radius is 45 cm.
Circumference =
circumference is also the same with perimeter
<h3>so, the answer is 141.37cm</h3><h3>to nearest tenth = 141.4cm</h3>
Answer:
m=8
Step-by-step explanation:
-88=-3(4m+5)-(1-3m)
-88=-12m-15-(1-3m) <- Distributive Property
-88=-12m-15-1+3m <- Open () if there is a negative negative the symbol equals positive
-88=-9m-16 <- Simplify
0=-9m+72 <- Add 88 to both sides
9m = 72 <- Add 9m to both sides
9m = 72
/9 /9
m=8
Answer:
The answer should be C
Step-by-step explanation:
Answer:
Part A: 5 inches³.
Part B: 302 inches³.
Part C: Yes. Explanation below.
Step-by-step explanation:
Part A: The cookie sandwiches appear to be flat cylinders. The volume for a cylinder is pi * r^2 * h.
In this case, the h = 1 inch and r = 1.25 inches.
pi * 1.25^2 * 1
= pi * 1.5625
= 3.14 * 1.5625
= 4.90625.
So, the volume of a single cookie sandwich is about 5 inches³.
Part B: As stated before, the volume of a cylinder is pi * r^2 * h.
In this case, the r = 4.5 inches, and the h = 4.75 inches.
pi * 4.5^2 * 4.75
= 3.14 * 20.25 * 4.75
= 63.585 * 4.75
= 302.02875.
So, the volume of the food storage container is about 302 inches³.
Part C: Given the calculations from Parts A and B, Jenny will be able to transport all the cookie sandwiches in the food storage container. This is because there are 56 cookie sandwiches, each with a volume of 5 cubic inches. That means that the cookie sandwiches will take up 5 * 56 = 280 cubic inches of space. There is about 302 cubic inches of space in the container, so there will still be 22 cubic inches of air inside the container after the cookies are inside.
Hope this helps!
It would be
14,494.2 - 282.6 = 14211.6
