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.
Quotient of means divide and the placement of the symbol is where the word "and" is located... the closest "and" unless you see "sum of", "product of", "difference of", or even another "quotient of" between it and "and".
In this case the first "and" is closest so the division sign will go there and the 2nd "and" will be replaced with a + sign.
Ways to write the answer:
9 ÷ (x + 1)
[9tan(θ) * 9cot(θ)] / 9sec(θ)
First cancel out the 9's:
tan(θ)cot(θ)/sec(θ)
Recall the following trig identities:
tan = sin/cos
cot = cos/sin
sec = 1/cos
Thus, we can rewrite the expression as:
[ (Sin(θ)/cos(θ)) *(cos(θ)/sin(θ)) ] / (1/cos(θ))
In the numerator, the sine's and cosine's cancel each other out:
1 / (1/cos(θ))
which we can rewrite as cos(θ).
Answer:
p = £7.00
Step-by-step explanation:
Represent the original price by p. Then 0.80p = £5.60, or p = £7.00.
If a price is discounted by 20%, the discounted price is (1 - 0.20), or 0.80, times the original price.
