Answer:
Her error was multiplying numerator by numerator ( that is Quantity of Bone-shaped treats)
Step-by-step explanation:
Sarah's calculation
Let
x = cost of 12 Bone-shaped treats
Quantity of Bone-shaped treats : price
5 : 3.5 = 12 : x
(5/3.5) = (12/x)
Cross product
3.5x=60 (Here is her error)
x=17.14
Correct calculation
Quantity of Bone-shaped treats : price
5 : 3.5 = 12 : x
5 / 3.5 = 12 / x
Cross product
5 * x = 3.5 * 12
5x = 42
x = 42 / 5
= 8.4
x = $8.4
Her error was multiplying numerator by numerator ( that is Quantity of Bone-shaped treats)
Instead of multiplying Quantity of Bone-shaped treats by cost
Answer:
≈ 15.73 in
Step-by-step explanation:
Since the volume of a cylinder is , we can set the equation,
= 1000
Since the radius of the circle is 4.5, we square it to get
= 1000
Dividing by 20.25 on both sides, we get
≈ 49.38
Dividing by 3.14 on both sides, we get
≈ 15.73 in
The answer is k = 0 and for some reason this has to be 20 characters
