Car leases generally allow only a certain number of miles to be driven. Myung’s lease included a charge of 25 cents per mile for all miles above 12,000 per year. If Myung had a 3-year lease and was charged $1,640 at the end of the lease, how many miles had she driven during the 3 years?
Answer:
197
Step-by-step explanation:
Divide 1640 by 25
1640/25=65
Then multiply 65 and 3
65x3=197

Step-by-step explanation:
question 1) equal angels
8+19)=(9x+9)
x=10°
8x+19=99°
question 2) equal angels
(3x-26)=2x
x=26°
3x-26= 52°
question 3) different angels
180-(x+10) = x+50
180-x-10=x+50
170-x=x+50
2x=120
x= 60°
x+10= 70°
x+50=120°
question 4) equal angels
3x-31=x+59
2x=90
x=45°
x+59=104°
question 5) equal angels
6x+3=7x-12
x=15°
6x+3=93°

How much will Jason earn, if he invests $8,000 at 7.5% interest rate for 18 months? How much will be in the account at the end of the 18 months?
Answer:
$8,900
Step-by-step explanation:
You don't say anything about compounding. If this problem involves only simple interest, then the interest will be i = p*r*t and the account balance will be i + p.
Here i = $8,000*0.075*1.5 (representing 18 months)
i + $900
At the end of 18 months there will be $8,000 + $900, or $8,900, in the account.
Answer:
$8,900
Step-by-step explanation:
Please help me! The questions are below! Thanks.
Answer:
I think it would be B
Step-by-step explanation:
because it has to be exact and the height can be the same so it has to be 1.4 more so yeah
Please help I’m confused math is hard!
Answer:
Step-by-step explanation:
basically, what they are asking you is to factor and then plug in the values (x=3; x=4) that they gave you.
first, you need to factor out the equation.
start with the original equation.
V=4x^3+10x^2+4x
factored form:
V= 2x(2x^2+5x+2)
next, you're going to want to plug in the values.
the answer asks for x=4, but you should do both.
v=2(3)(2(3)^2+5(3)+2)
do not forget to do the exponents before!
v=6(18+15+2)
v=6(35)
v=210 ft^2
that's the answer for if x was equal to 3.
V= 2x(2x^2+5x+2)
don't forget to write the original equation first.
V=2(4)(2(4)^2+5(4)+2)
V=8(36+20+2)
V=464 ft^2⬆is your answer! hope this helped!!

Consider these two triangles. Triangle A'B'C' is the dilated figure with a scale factor of 3.
Triangle A B C has side lengths 5 centimeters, 7 centimeters, 3 centimeters. Triangle A prime B prime C prime.
What can be concluded about the two triangles? Check all that apply.
1) The triangles are similar.
2) The corresponding sides are proportional.
3) The length of A'B' is 15.
4) The length of B'C' is 9.
5) The dilation is a reduction.

Step-by-step explanation:
i did the warmup
help? thanks :D have a good day
Answer:
option a
Step-by-step explanation:
as 145 +10 = 155°
and total angle measure of triangle is 180
so
180-155 = 25°
in option a one angle is 10
other is 25 so obviously last angle will be 145
and same is in the triangle abc
one angle is 10 other is 145 and last is 25
both hve same measures thus are same triangles.

mean absolute deviation 78, 45, 60, 33, 84
its number 2!
Answer: Mean Absolute Deviation Calculator
Instructions
This calculator computes the mean absolute deviation from a data set:
You do not need to specify whether the data is for an entire population or from a sample. Just type or paste all observed values in the box above. Values must be numeric and may be separated by commas, spaces or new-line. Press the "Submit Data" button to perform the computation. To clear the calculator, press "Reset".
What is the mean absolute deviation
The mean deviation is a measure of dispersion, A measure of by how much the values in the data set are likely to differ from their mean. The absolute value is used to avoid deviations with opposite signs cancelling each other out.
Mean absolute deviation formula
This calculator uses the following formula for calculating the mean absolute deviation:
$ MAD =\frac{1}{n} \sum_{i=1}^n |x_i-\bar{x}|$
where n is the number of observed values, x-bar is the mean of the observed values and xi are the individual values.
