Answer:
Step-by-step explanation:
Circumference of a circle is expressed as;
C = 2πr
r is the radius
Given
radius of Earth r1 = 6,371.0 kilometers
the radius of Earth's Moon r2 = 1,737.5 kilometers
The difference in their circumference will be expressed as;
C = 2π(r1-r2)
C = 2π(6371.0-1737.5)
C = 2π(4633.5)
C = 2(3.14(4633.5))
C = 29,098.38km
C = 29,098.4
Hence the difference in their circumference to the nearest km is 29,098.4km
Answer:
We calculate for the circumferences of Earth and moon by using the equation,
C = 2πr
For Earth,
C = 2π(6371 km) = 40030.2 km
For Moon,
C = 2π(1737.5 km) = 10917.0 km
The difference between the two circumferences is 29113.2 km approximately.

Hannah paid for 2.5 pounds of peanuts with a ten-dollar bill. She received $1.20 in change from the cashier. What was the price, per pound, for the peanuts?
Answer:
$3.52
Step-by-step explanation:
10 - 1.20 = 8.8. Hannah had change, so you need to subtract it to find out how much she paid for 2.5 pounds.8.8/2.5 = 3.52. You are dividing to find the unit rate, which is the price of one pound.Kyle missed 3 questions on the math exam. If he missed 15% of the questions, how many questions were on the exam all together?

Josiah invested $96,000 in an account paying an interest rate of 3.5% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $153,400?
The number of years it will take for the value of the money in the account to reach $153,400 would be = 17 years.
What is simple interest?Simple interest is defined as the amount of money that is received as an extra cash based on an investment made in an account.
The principal amount of money invested= $96,000
The rate of interest = 3.5%
The total interest on the principal amount = $153,400- $96,000 = $57,400
The time for this investment= ?
Using the formula for simple interest= p×T×R/100
57,400 = 96,000 ×T× 3.5 /100
Make T the subject of formula;
T = 57,400×100/96,000×3.5
T = 5740000/336000
T = 17 years (approximately)

M is the midpoint of AB. If the coordinates of point A are (7,4) and the coordinates of B are (1,2), what are the cooridnates of M?
Answer:
M(4, 3 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = A(7, 4) and (x₂, y₂ ) = B(1, 2) , thus
M = ([tex]\frac{7+1}{2}[/tex], [tex]\frac{4+2}{2}[/tex] ) = ( [tex]\frac{8}{2}[/tex], [tex]\frac{6}{2}[/tex] ) = (4, 3 )

One of the slowest fish is the blenny
fish. The function y = 0.5x describes
how many miles y the fish swims in
x hours. Graph the function. Use the
graph to estimate the number of miles
the fish swims in 3.5 hours.
.
Answer:
It swims 1.75 miles in 3.5 hours. X stands for hours so x=3.5. Y stands for miles so y=1.75.
Step-by-step explanation:
your equation is y=0.5x
we know x=3.5
so y= 0.5(3.5)
solve and you get y= 1.75
so in (x,y) intercept format (3.5,1.75) and you can make a graph and label your x intercepts hours and your y intercepts miles traveled.
The number of miles the fish swims in 3.5 hours is 1.75 miles.
The equation of a straight line is:
y = mx + b;
y, x are variables, m is the slope of the line and b is the y intercept.
Given the function: y = 0.5x;
where y represent the miles the fish swims in x hours.
The graph of the function is plotted using geogebra online graphing tool.
From the graph, the number of miles the fish swims in 3.5 hours is 1.75 miles.
