Answer:
The volume of the air that the beach ball will hold is 113,142.85 cm³.
Step-by-step explanation:
Sphere:
- It is a three dimension shape.
- It has a center.
- Volume=
, r is the radius of it. - Surface area= 4πr².
Given that,
Ariel is filling a giant ball with air.
The ball is sphere in shape.
The volume of air = The volume of the ball.
The radius of the beach ball is 30 cm.
The volume of the ball is 
cm³
=36,000π cm³
=113,142.85 cm³
The volume of the air that the beach ball will hold is 113,142.85 cm³.
One table weighs 157.84 pounds together they weigh 235.68 pounds. Take 235.68-157.84 you get 77.84 take that divided by 8 for 8 chairs 9.73 pounds per chair.
Add up all the money for college and the note books ect then you have your answer
Answer:
Step-by-step explanation:
a+b=9500 equation 1
35a+55b=432500 equation 2
a=9500-b modified equation 1 to isolate a
35(9500-b)+55b=432500 substitute value of a in equ 1 into value of a equ 2
332500-35b+55b=432500
20b=100000
b=5000
solve for a
a + b=9500
a + 5000=9500
a=4500
check answer:
35a+55b=432500
35(4500)+55(5000)=432500
157500+275000=432500
432500=432500
Answer:
Step-by-step explanation:
<em>Cost of game = $120</em>
<em>Current savings = $30</em>
<em>Rate for babysitting (per hour) = $5/hour</em>
<em></em>
<em>So, required equation is :-</em>
<em>120 = 5h + 30</em>
<em>5h = 90</em>
<em>h = 18</em>
<em></em>
<em>She must make $90 by babysitting for 18 more hours.</em>
