Answer:
51.47 cubic inches
Step-by-step explanation:
Given the volume of the sphere is: 27 cubic inches
As the know, the following formula used to determine the volume of a sphere:
V = 4/3 πr³ where r is the radius of the sphere
In this situation, we have: V = 27 cubic inches
<=> 4/3 πr³ = 27
<=> r³ = 81/4π
<=> r = 1.86
However, the length of side of the cube is 2 times the radius of the sphere when the sphere is inside the cube
=> the length of the side = 2r = 2*1.86 = 3.72 inches
=> the volume of the cube is:
where x is the length of the side
<=> V =
= 51.47 cubic inches
Hope it will find you well
Answer:
83.07
Step-by-step explanation:
If you multiple the original price $78 times the sale tax in decimal form 0.065 you get 5.07, $78 + $5.07 = 83.07.

Answer:
B, B, A.
Step-by-step explanation:
5x means 5 multiplied by x, so is it A, B or C? the product, because that means multiplied. a is B.
For b, we can see that 7 is a constant, because it isn't being multiplied by anything.
For c, 2y is 2 multiplied by y. Y would be the variable, and 2 would be the coefficient.
Answer:
y = 1.50x + 4 ;
Step-by-step explanation:
Given that bike rental cost $4 plus $1.50 per hour
From the information given, the change in y per unit change in x is the value of the slope ;
Therefore, Given that total cost = y and x) number of hours
Change in cost per change in number of hours) 1.50 = slope ; intercept = constant = $4
The equation, in slope intercept form :
y = mx + c
y = 1.50x + 4
