Answer:
Step-by-step explanation:
A) 700 cookies in 7 days.
im not sure of B
The answer is: 45 .
________________________________
3/5 * 75 = 3/5 * 75/1 ;
The "5" cancels to a "1"; and the "75" cancels to a "15" ;
since "75÷5 = 15" ; and since "5÷5 =1" .
So, rewrite the problem:
3/1 = 15/1 = 45/1 = 45.

Other method:
___________________________
3/5 * 75 = 6/10 * 75 = 0.6 * 75 = 45.0 = 45 .

Answer: the diameter of the can is 2.8 inches
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder.
h represents the height of the cylinder.
π is a constant whose value is 3.14
From the information given,
height = 4.5 inches
Volume of can = 454 millilitres
1 cubic inch = 16.387 millilitres
Converting 454 millilitres to cubic inches, it becomes
454/16.387 = 27.7 cubic inches
Therefore
27.7 = 3.14 × r² × 4.5
27.7 = 14.13r²
r² = 27.7/14.13
r² = 1.96
r = √1.96
r = 1.4
Diameter = 2 × radius
Diameter = 2 × 1.4 = 2.8 inches
Answer:
7/5 is the constant variation.
Hope this helps! Have a great day!
