Answer: 800pi inches

=======================================

Explanation:

The formula to find the circumference of a circle is
C = pi*d
where
C = distance around the circle (aka circumference)
pi = 3.14 approximately
d = diameter

We know that the diameter of the wheel is d = 8, so
C = pi*d
C = pi*8
C = 8pi
is the circumference of the wheel

One full rotation will have the wheel cover a distance of 8pi inches. Imagine that wet paint is on the outer surface of the wheel. If the wheel is rolled out in a straight line, then the wet paint would cover a linear distance of 8pi inches along the flat ground. This is one full rotation, so 100 rotations covers 100*8pi = 800pi inches

Note: if we use pi = 3.14 as the approximation, then the hamster ran approximately 800*pi = 800*3.14 = 2512 inches if the wheel could move

A red apple has mass of 20 grams .you cut it into 5 slices. what about the aplles has changed ?

Nutka1998 [239]

Well you have cut it into smaller pieces so it would be I guess 4 grams now because 20 divided by 5 is 4.

the sum of two numbers is 52. their difference is 9. write and solve system of equations to find the 2 numbers

sergiy2304 [10]

Hey there :)

Let us first translate words into mathematics!

Sum of 2 numbers is 52
x + y = 52

Difference of 2 numbers is 9
x - y = 9

(eq.1) x + y = 52
(eq.2) x - y = 9
Add both equations : x + y = 52
+ x - y = 9
2x = 61
x = 30.5
We now have the value of x, substitute into eithe formulae to find y
x - y = 9 , 30.5 - y = 9 , 30.5 - 9 = y , 21.5 = y
x + y = 52 , 30.5 + y = 52 , 52 - 30.5 = y , 21.5 = y

x = 30.5
y = 21.5

HELP WILL MARK BRAINLIEST!!!

Answer:

y = 12

Step-by-step explanation:

set up equation for 'y varies inversely with x': y = k/x

where 'k' is the constant of variation

8 = k/6

therefore, k = 48

value of y when x = 4: y = 48/4; therefore, y = 12
