an investigator traveling on official buisness in his personal vehicle had to make emergancy repairs to the vehicle. he paid $150 for the repairs to the vehicle for repairs plus 15% of this amount to compensate the mechanic for the repair work performed overtime. the investigator's office reimbbursed him $100 plus 40% of any amount over $100. which one of the equations represent the amount that the investigator was reimbursed for the repairs?
Answer:
x+40%of x
Step-by-step explanation:
here x is the 100$
If y varies directly with x and y = 21 when x = 3, find y if x = 5.
First, find the direct variation equation. y = [ ? ] x
when y = 21, x = 3
when y and x vary directly, that means there is something that you multipy x that gets you to y.
to solve for this number, you divide y by x.
21= 3=7
this means to go from x to y, you multiply x by 7.
7x = y
we can use this to solve for x when y = 42
7x = 42
divide both sides by 7
X = 6
when y = 42, x = 6

Answer:
[tex]35.33\ m^3[/tex]
Step-by-step explanation:
Given that,
Height of the cylindrical well, h = 20 m
The diameter of the well, d = 1.5 m
Radius, r = 0.75 m
We need to find the volume of the well. This will be the amount that is dug out to make a well. So,
[tex]V=\pi r^2 h\\\\V=3.14\times (0.75)^2\times 20\\\\V=35.33\ m^3[/tex]
So, [tex]35.33\ m^3[/tex] soil was dug out to make a well.
Initially, a population of rabbits was found to contain 192 rabbits. It was estimated that the population was growing exponentially at the rate of 10% per day. Estimate the population after 52 days.
Answer:
the population after 52 days is $34,804.27
Step-by-step explanation:
Given that
There is a population of the rabbits i.e. 192
And, the growth rate is 10%
We need to find out the population after 52 days
So,
= 192 × e^(0.10 × 52)
= $34,804.27
hence, the population after 52 days is $34,804.27

Emelia pays $24 to rent a boat at the lake for up to 6 hours she constructs the inequality and number line below to represent the number of hours x she can use the boat
Answer:
She has an initiall amount of 6 hours, so if T is the amount of time that passed since she rented the boat, the inequality that describes this system is:
0≤ T ≤ 6
This means that she can use the boat from 0 hours to 6 hours, here we are allowing the intermediate values because, of course, she can return the boat earlier than in the given time.
From this we have that the maximum time left that she has can be written as:
x + T = 6
so if T = 3h, meaning that 3 hours passed, she has:
X + 3 = 6
x = 6 - 3 = 3
3 hours left.

What is the lower quartile of the annual wind speeds in Chicago?
a) 9.1
b) 11.5
c) 8.2
d) 10.75
Answer:
9.1
Step-by-step explanation:
The lower quartile, denoted as Q1, gives the value of the lower quartile, from a box plot, the value of the lower quartile is the value at the starting point of the box. In the box plot given for the windspeed in Chicago, the starting point of the box is the point marked with the reading 9.1. Hence we can conclude that the lower quartile is 9.1
The sides of an isosceles triangle have lengths of 10, 10, and 4. Find the measures of the base angles.
Answer:
The base angles measure 78.46 degrees to the nearest hundredth.
Step-by-step explanation:
Applying the Cosine Rule:
10^2 = 10^2 + 4^2 - 2.4.10cosX where X is a base angle.
cos X = (100 - 100 - 16)/ (-80)
cos X = -16/-80
cos X = 0.2
X = 78.463 degrees

Answer:
x = 5
m∡B = 66°
Step-by-step explanation:
these two angles are same-side interior angles, which are supplementary
8x + 74 + 2x + 56 = 180
10x + 130 = 180
10x = 50
x = 5
m∡B = 2(5) + 56 = 66°

Step-by-step explanation:
Sara is planning on fully renovating her kitchen. She figures that this will cost a total of $25,750. If Sandra already has $21,400 saved up, what annual interest rate
compounded semiannually would Sara need to earn in order to have the required
funds if she invests her money for 2.5 years?
Answer:
She needs an annual interest rate of 7.54%.
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
She figures that this will cost a total of $25,750.
This means that [tex]A = 25750[/tex].
Sandra already has $21,400 saved up
This means that [tex]P = 21400[/tex].
Semianually compunding, 2.5 years.
This means that [tex]n = 2, t = 2.5[/tex]
What interest rate?
We have to find r. So
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]25750 = 21400(1 + \frac{r}{2})^{2*2.5}[/tex]
[tex](1 + 0.5r)^5 = \frac{25750}{21400}[/tex]
[tex]\sqrt[5]{(1 + 0.5r)^5} = \sqrt[5]{\frac{25750}{21400}}[/tex]
[tex]1 + 0.5r = (\frac{25750}{21400})^{\frac{1}{5}}[/tex]
[tex]1 + 0.5r = 1.0377[/tex]
[tex]0.5r = 0.0377[/tex]
[tex]r = \frac{0.0377}{0.5}[/tex]
[tex]r = 0.0754[/tex]
0.0754*100% = 7.54%
She needs an annual interest rate of 7.54%.
HELP ME PLEASE I REALLY NEED THE HELP
Answer:
Answer = 126 square inches
Step-by-step explanation:
Square area formula is Area = s^2 (replace the s with the side length)
Square area --> Area = 4^2 Area = 16in
Parallelogram area formula is Area = h * b (replace h with height length and replace b with base length)
Parallelogram area --> Area = 3.5 * 10 Area = 35
Rectangle area formula is Area = w * h (replace width and height)
Rectangle area --> Area = 12.5 * 6 Area = 75
Then add them all up 75 + 35 + 16 = 126 square inches

A survey of 1,158 adults nationwide asked, "wjat irks you most about the action of othwr motorosts?" The response "tailgaters" was given by 294 people. What percent of those surveyed were most irked by tailgaters? Round to the nearest tenth of a percent.
Answer:
25.4%
Step-by-step explanation:
Here, we are to calculate the sample proportion :
Number sampled, n = 1158
x, = number of sample irked by tailgaters = 294
Sample proportion, Phat = x / n
Phat = 294 / 1158 = 0.25388
Phat = 0.25388 * 100% = 25.388%
= 25.4%

1. How many 5-digit numbers are there for which the last digit is not a 6 or an 8, the digit 6 appears exactly once, and the number is even
Answer:
8019 possible 5 digit numbers
Step-by-step explanation:
Available number to pick from are a total of 10 which are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
>> Now, let's consider when the first digit is 6 since we are told that 6 can appear only once.
For the first digit, it's only 1 way.
For the 2nd, 3rd, and 4th digit, we have 9 digits to pick from. Which is 9 ways each.
While for the 5th digit, it can't be 6 or 7. And it has to be even and so, we can pick only 0, 2, 4. Thus, we have 3 ways to choose.
So total number of ways here = 1 × 9 × 9 × 9 × 3 = 3 × 9³ ways
>> Now, let's consider when the 2nd digit is 6 since we are told that 6 can appear only once.
For the 1st digit, since 6 is not possible, and also 0 is not possible because a 5 digit number can't start with zero as it would no longer be a 5 digit number.
Thus, there are 8 ways to choose here.
For the second, third and fourth digits, there will be 9 ways each to chops.
While for the fifth digit, there will be 3 ways to choose.
Total number of ways here = 8 × 1 × 9 × 9 × 3 = 24 × 9² ways
>> When the third digit is 6, number of ways to choose will be same as above = 24 × 9² ways
>> When the fourth digit is 6, number of ways to choose will be same as above = 24 × 9² ways
We can't say none of the digits is 6 because we are told it appears exactly once.
Thus, total possible 5 digit numbers are;
(3 × 9³) + 3(24 × 9²) = 8019 possible 5 digit numbers
The surface areas of the two solids shown above are equal.
O A. True
O B. False
Answer:
False
Step-by-step explanation:
If we were to flip the solid on the left so its parallel to the solid on the right, we would be able to compare the two more easier.
We can see that the right solid has dimensions of:
L = 1 cm
W = 3 cm
H = 5 cm
The left solid has dimensions of:
L = 1
W = 2
H = 7
If we were to add these all up, they would not equal.
R: 1 + 3 + 5 = 9
L: 1 + 2 + 7 = 10
Find a polynomial f(x) of degree 3 that has the following zeros. -5, 8, 2 Leave your answer in factored form
Answer:
f(x) = (x+5)(x-8)(x-2)
Step-by-step explanation:
If we know the zeros, the polynomial is of the form
f(x) = (x-a)(x-b)(x-c) where a,b,c are the zeros
f(x) = (x - -5)(x-8)(x-2)
f(x) = (x+5)(x-8)(x-2)
Answer:
f(x) = (x + 5)(x - 8)(x - 2)
Step-by-step explanation:
Given a polynomial with zeros x = a , x = b , then the corresponding factors are
(x - a) and (x - b)
The polynomial is a product of the factors, that is
f(x) = (x - a)(x - b)
Here the zeros are x = - 5, x = 8, x = 2, then corresponding factors are
(x - (- 5)), (x - 8), (x - 2) , that is
(x + 5), (x - 8), (x - 2) and the polynomial is
f(x) = (x + 5)(x - 8)(x - 2)
