Answer:
Length is 7, Permimeter is 28
Step-by-step explanation:
Perimeter=4×side
(8x-28)=4×x [let length be x]
8x-28=4x
8x-4x=28
4x=28
x=28÷4
x=7
Length = x = 7
Perimeter=(8x-28)
=(7×8)-28
=56-28
=28
The slope is defined as
So, we have the follwing equation:
Answer:
Hello! answer: 2
Step-by-step explanation:
Hello the mean is just all the numbers added up in a data set divided by the amount of numbers in the data set to get the average! So... 2 + 1 + 3 + 2 = 8 theres 4 numbers so we would divide by 4 so... 8 ÷ 4 = 2 therefore the mean is 2 HOPE THAT HELPS!
Answer:
The answer to the first question is 32 but I don't know the slope of the line, sorry
The student has to pay back $1240
Further explanation:
Simple interest is calculated on the principal amount. It can be applied only one or over a period of time. For example, if the interest is to be applied annually then it will be calculated each year on the starting principal amount.
Given
Amount = Principal amount = P_0 = $1000
Interest rate = r = 8%
time = t = 3 years
The formula for calculating interest is:
The interest for three years will be $240.
The amount to be paid back by the student is:
The student has to pay back $1240
