Answer:
5.2 ft.
Step-by-step explanation:
First you want to find the circumference of the circle. Given the radius 5ft you can then multiply it by 2 to get the diameter to make the equation for circumference much easier. 2*5=10. the diameter is 10ft.
Next the formula for circumference with diameter is π(d). Our diameter is 10 so plug it in and you get π(10) which equals about 31.4.
With the 60 degree you have to know that a circle is a full 360 degrees. 60 is 1/6 of 360 in meaning the distance the weight at the end of the cord will move is 1/6 of the circumference of this circle. Therefore you need to do 1/6*31.4 which equals about 5.2.
Answer:
or
27 
Step-by-step explanation:
Any regular whole number (37 for example) is over one so it would look like 
. Multiplying fractions involve just multiplying the numerators and denominators together, therefore it would look like ×. Now just multiply the top and bottom numbers together and this will leave you with . But if you'd like to make it into a mixed number (more simplified version of ) then you would get 27 .
Answer:
No The reactions are not inverses to each other
Step-by-step explanation:
f(x) = 3x + 27
Let f(x) be y
y= 3x+27
subtracting 27 on both sides
3x = y - 27
x= (y-27)/3
= y/3 - 9
inverse function is x/3 -9 not x/3 + 9
Therefore, not an inverse

Answer:
We need to take the diameter and divide by 2 to find the radius
Step-by-step explanation:
The volume of a sphere is found by
V = 4/3 pi r^3
So we need the radius
We know the diameter
r = d/2
We need to take the diameter and divide by 2
Answer:
1 week
Step-by-step explanation:
<u><em>The correct question is</em></u>
Amira has 3/4 of a bag of cat food .Her cat eats 3/4 of a bag per week . How many weeks will the food last ?
we know that
To determine how many weeks her food will last, we take the amount of food and divide by how much she feeds her cats.
3/4 bag ÷ 3/4 bag per week
Multiply in cross
