Answer:
The cost of 6 cans of soup = $7.8
Step-by-step explanation:
The cost of 10 cans of soup = $13
The number of cans needed for the soup = 6
Now, Cost of 1 can of soup =
= $13 / 10 =$1.3
⇒The cost of 1 can of soup is $1.3
Now, The cost of 6 cans of soup = 6 x Cost of 1 can
⇒ 6 x $1.3 = $7.8
Hence, the cost of 6 cans of soup = $7.8
Answer:
3/4
Step-by-step explanation:
It's three fourths, she ate one fourth.
The area would be 144cm^2.
In order to find the area, we need to know the length of the rectangle. We can find that using the perimeter formula.
2l + 2w = P
2l + 2(36) = 80
2l + 72 = 80
2l = 8
l = 4
So now that we know the length is 4, we can find the area using that formula.
A = lw
A = (4)(36)
A = 144
Since there are no figures given, I will give an example.
You are given a silo that is shaped as
a closed cylinder with a conical end. The diameter of the silo is 4 ft, the
length of the cylindrical part is 6 ft, and the entire length of the silo is
10.5 ft. Suppose that you are asked to find the total volume of
grains that can be stored in the silo.
Given:
Cylinder part
D = 4 ft
H = 6 ft
Cone part
H = 10.5 – 6 = 4.5ft
D = 4ft
Required:
Volume of silo
Solution:
V of cylinder = πr²H
V of cylinder = π(4/2)²(6)
V of cylinder = 75.4 ft³
V of cone = πr²H/3
V of cone = π(4/2)²(4.5/3)
V of cone = 18.85 ft³
Total volume = 94.25 ft³
