So,
If she keeps one-fourth for herself, she will keep:
72 * 0.25 = 18
That leaves the rest for her friends.
72 - 18 = 54
Her friends will get 54 "Suites."
Answer:
<u>h = V/r²</u>
Step-by-step explanation:
The formula is :
- V = r²h (actually 1/3πr²h in real life)
Solving :
- Dividing both sides by r²
- V/r² = r²h/r²
- <u>h = V/r²</u>
Answer:
4.5 miles per hour is her rate in miles per hour
Step-by-step explanation:
We want to convert 20 ft per second to miles per hour
If she jogs 20 ft in 3 seconds , then in one second , she will jog 20/3 ft
So convert 20/3 ft/second to miles per hour
Mathematically;
1 mile = 5280 feet
So one feet = 1/5280 mile
1 hour = 3600 seconds
1 second = 1/3600 hour
So, to go from miles/hour to ft/second ; we shall multiply by 1/5280 and divide by 1/3600
Hence; we have;
(20/3 * 1/5280)/1/3600
= 20/3 * 1/5280 * 3600/1
= 4.4545 which is 4.5 miles per hour
30 divided by 7 is 4.2z
It snowed 4.2 inches per hour
Answer:
62.7°
Step-by-step explanation:
9 = Hypotenuse
8 = Opposite
In this question we have to use some trigonometry to work out angle EFG. The first thing we need to identify is will formula will we use out of the following:
Sin⁻¹ = Opposite ÷ Hypotenuse
Tan⁻¹ = Opposite ÷ Adjacent
Cos⁻¹ = Adjacent ÷ Hypotenuse
We know which formula to use because the length won't be in the triangle for example we will be using the Sin triangle because we don't have an adjacent. If we don't have an adjacent then the other formula's won't work.
Now we substitute in the values
Sin⁻¹ = Opposite ÷ Hypotenuse
Sin⁻¹ = 8 ÷ 9
The value of angle EFG is 62.73395555
