150 miles
50 mph for three hours
So multiply 50 and 3
150
Answer is 13 yards of ribbon
Step by step
She started out with $25
She had a remainder of $22.14
Subtract
25 - 22.14 = $2.86 she spent on ribbon
Divide $2.86 by .22 per yard = 13 yards
Problem solved
<span>1.6m − 4.8 = −1.6m
<u>- 1.6m -1.6m
</u> -4.8 = -3.2m
<u>
</u>divide both sides by -3.2
m = 1.5</span>
Answer:
Equal to!
Step-by-step explanation:
2 x 1.08 is 2.16
(1.08/100) x 200 = 2.16
2.16 = 2.16
Answer:
12 inches
Step-by-step explanation:
Suppose the ice cream scoop has the shape of a sphere of a radius (r) inches.
Thus, the top of the cone will also have a radius (r) inches.
Let consider h to be the height of the cone in inches.
So, the objective is to make the volume of the scoop of the ice cream to be the same as the volume of the cone.
To do that; we need to equate both volumes together and make h the subject of the formula:
The volume of a sphere = 4/3 πr³ and the volume of a cone = 1/3πr²h
4/3 πr³ = 1/3πr²h
Multiply both sides by 3
4πr³ = πr²h
4r = h
h = 4(3)
h = 12 inches
To contain all the ice cream inside the cone, the height of the ice cream cone needs to be 12 inches tall
