Answer:
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
or 
Let
x -----> the amount of weight
y ----- the amount a spring will stretch
we know that
For x=80 lb, y=2.1 in
<em>Find the value of k (constant of proportionality)</em>
substitute the values
The linear equation is
How far will it stretch when 40 pounds is attached?
For x=40 lb
substitute the value of x in the linear equation and solve for y
Answer:
a. 36 blueberries and 12 strawberries
b. 16 blueberries and 4 strawberries
Step-by-step explanation:
The computation of each berry in the bowl is shown below;
a. Total 48 berries
The Ratio of blueberries to strawberries is 9:3
So, the blueberries is = 48 × 9 ÷ (9 + 3) = 36
And, the strawberries is = 48 × 3 ÷ (9 + 3) = 12
b. Total 20 berries
The Ratio of blueberries to strawberries is 4:1
So, the blueberries is = 20 × 4 ÷ (4 + 1) = 16
And, the strawberries is = 20 × 1 ÷ (4 + 1) = 4
