22. Write a polynomial in simplest form
to express the shaded area in terms of .
9x2
7x
Answers
Answer:
The area of the shaded portion is;
A= π (81x^4 - 49x^2)
Step-by-step explanation:
Looking at the given figure, the area of the shaded part is simply the area of the bigger circle minus the area of the smaller circle
The bigger circle has a radius of 9x^2
The smaller circle has a radius of 7x
The radius is the distance from the center to any part of the circumference
The area of a circle can be calculated using the formula;
A = pi * r^2
For the bigger circle, we have;
A = pi * (9x^2)^2
A = pi * 81x^4
for the smaller circle, we have;
A = pi * (7x)^2
A = pi * 49x^2
So the area of the shaded portion will be;
A= π (81x^4 - 49x^2)

Roy hit 3 less than 4 times the number of balls during baseball practice than Joe did. Together the boys hit 52 balls. How many balls did Joe hit?
Answers
Joe = x
Roy = 4x - 3
They add up to 52 balls
x + 4x - 3 = 52
5x - 3 = 52
5x = 55, x = 11
Since Joe is x, he hit 11 balls
Answer:
Joe hit 11 balls Roy hit 41
Step-by-step explanation
Joe = J
Roy = 4J-3 (4times Joe less 3)
J+ 4J-3 = 52
5J -3 = 52
Add 3 on both sides
5J = 55
Divide both sides by 5
J= 11
Joe = 11
11X4 = 44
44-3 = 41
Roy 41
11+41 = 52
Gerardo works at an ice cream shop each flavor of ice cream is stored in a right cylindrical tub that measures approximately 9 inches high with a radius of 5 inches Gerardo uses an ice cream scoop that makes spherical scoops of ice cream with a diameter of 2.5 inches If gerardo opens a new tub of chocolate ice cream and scoops 37 scoops of chocolate ice cream about how much chocolate ice cream in cubic inches is left in the tub
Answers
Answer:
Volume left = 404.32 cubic inches
Step-by-step explanation:
volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h
volume of ice cream in the cylindrical tub = [tex]\frac{22}{7}[/tex] x [tex]5^{2}[/tex] x 9
= [tex]\frac{22}{7}[/tex] x 25 x 9
= 707.1429
Volume of ice cream in the cylindrical tub is 707.14 cubic inches.
The ice cream scoop has a spherical volume, so that;
volume of a sphere = [tex]\frac{4}{3}[/tex][tex]\pi[/tex][tex]r^{3}[/tex]
r = [tex]\frac{2.5}{2}[/tex]
= [tex]\frac{5}{4}[/tex] inches
volume of the scoop = [tex]\frac{4}{3}[/tex] x [tex]\frac{22}{7}[/tex] x [tex](\frac{5}{4} )^{3}[/tex]
= [tex]\frac{4}{3}[/tex] x [tex]\frac{22}{7}[/tex] x [tex]\frac{125}{64}[/tex]
= 8.1845
volume of the scoop is 8.19 cubic inches.
If he scoops 37 scoops,
volume of the 37 scoops = 37 x 8.1845
= 302.8265
volume of 37 scoops is 302.83 cubic inches.
Volume of ice cream left in the tub = 707.1429 - 302.8265
= 404.3164
Volume of ice cream left in the tub is 404.32 cubic inches.

Write your answer in simplest form.
Answers
it would depend how much you actually used, but you would take the amount you used and divide it by the total amount of yarn. so if the yarn was 4m long and you used 2m then it would be 2/4 which is 0.5 which is also 50%, so half the yarn was used.

A soccer ball is kicked from the ground with an initial upward velocity of 64 meters per second, and the height of the ball can be represented by the equation h = -16t^2 + 64t. After how many seconds will the ball hit the ground?
Answers
Answer:
t = 2 seconds
Step-by-step explanation:
Given that,
h = -16[tex]t^{2}[/tex] + 64 t
where h and t have their usual meaning.
To determine the number of seconds required of the ball to hit the ground, differentiate the given equation with respect to t.
0 = -32 + 64
So that,
32t = 64
t = [tex]\frac{64}{32}[/tex]
t = 2
The ball will hit the ground in 2 seconds.

Ratio..A candy store sells snacks by weight. A six ounce bag of candy cost $3.60. Predict the cost of a 2ounce bag.
Answers
Answer:
A 2 ounce bag costs $1.2.
Step-by-step explanation:
With the information provided, you can use a role of three to find the cost of a 2 ounce bag given that you know that a six ounce bag costs $3.60.
6 ounce bag → 3.60
2 ounce bag → x
x=(2*3.60)/6
x=7.20/6
x=1.2
According to this, the answer is that a 2 ounce bag costs $1.2.
