If the first of three consecutive integers is subtracted from 138, the result is the sum of the second and third. What are the integers?
Answer:
45, 46, 47Step-by-step explanation:
n, n + 1, n + 2 - three consecutive integers
The equation:
138 - n = (n + 1) + (n + 2)
138 - n = n + 1 + n + 2 combile like terms
138 - n = 2n + 3 subtract 138 from both sides
-n = 2n - 135 subtract 2n from both sides
-3n = -135 divide both sides by (-3)
n = 45
n + 1 = 46
n + 2 = 47
The three consecutive integers in question are 45, 46, and 47. This was solved by setting up and solving a simple algebraic equation.
Explanation:Solution:Let the three consecutive integers be x, x+1, and x+2. According to the problem, the sum of the second and third integers is equal to 138 minus the first one. This can be written mathematically as:
x + (x + 1) + (x + 2) = 138
Solving this equation gives:
3x + 3 = 138
3x = 135
x = 45
Hence, the three consecutive integers are 45, 46, 47.

Tonya bought gifts for her family that cost $25, $14, $33, and $19. She has to buy one more gift and wants her mean cost to be $25. What should she spend on the last gift?
____________________________________________________
Answer:
Your answer would be $34.
____________________________________________________
Step-by-step explanation:
In order to get the mean cost that she wants from the gift, we would need to get the numbers that we already had, and have another set of row with the amount of gifts she needs with the mean she wants.
Here is how it should look like:
$25 $14 $33 $19 x
$25 $25 $25 $25 $25
We are trying to find the number for "x"
Therefore, we would need to use the process of adding, then subtracting after.
Lets add:
[tex]25+14+33+19=91\\\\25+25+25+25+25=125[/tex]
What we would do now is subtract the numbers in order to get the price that Tonya wants from her gift, if she buys another gift.
[tex]125-91=34[/tex]
Tonya should spend $34 on her last gift.
$34 should be your FINAL answer

Henry works at a computer store. He is paid $14.00 per hour, plus 5% commission. He worked 8 hours and sold 6 computers today for a total of $5,790. Henry wants to determine how much he earned. To calculate his pay, Henry multiplies 14 × 8, then adds the product to 5,790, then multiplies the sum by 0.05. Is his calculation correct?
A) Yes, Henry's calculation is correct.
B) No, he should have multiplied $5,790 by 0.05.
C) No, he should have added $112 to $5,790.
D) No, he should have multiplied 112 by 0.05.
No he should have multiplied 5,700 by 0.05
Answer:
The correct option is B) No, he should have multiplied $5,790 by 0.05.
Step-by-step explanation:
Consider the provided information.
He is paid $14.00 per hour, plus 5% commission. He worked 8 hours and sold 6 computers today for a total of $5,790.
Now find his total earning as shown:
$14 × 8 = $112
It is given that he sold 6 computers for a total of $5,790 and he gets a commission of 5% of total sale.
5% = [tex]\frac{5}{100}=0.05[/tex]
Now multiply 0.05 with $5,790
$5,790 × 0.05 = $289.5
Hence, the total income is $112+$289.5=$401.5
To calculate his pay, Henry multiplies 14 × 8, then adds the product to 5,790, then multiplies the sum by 0.05.
Henry's calculation is incorrect as he needs to multiply 5,790 with 0.05 and then he need to add the product of 14 × 8
Therefore, the correct option is B) No, he should have multiplied $5,790 by 0.05.

Find the circumference of a circle with an area of 254.47 square inches.
Answer:
56.5 inches
Step-by-step explanation:
We are given the area of a circle and we are to find the circumference of the same circle.
We know that the area of a circle is given by [tex]\pi r^2[/tex] so equating the given value to get.
[tex]\pi r^2=254.47[/tex]
[tex]r^2=\frac{254.47}{\pi }[/tex]
[tex]r=\sqrt{81.00}[/tex]
r = 9 inches
Since we now know the radius of the circle so we can find its circumference.
Circumference of circle = [tex]2\pi r[/tex] = [tex]2\pi (9)[/tex] = 56.5 inches
Answer: 56.54 in
Step-by-step explanation:
The area can be calculated with this formula:
[tex]A=\pi r^2[/tex]
Where r is the radius
And the circumference can be calculated with this formula:
[tex]C=2\pi r[/tex]
Where r is the radius
Solve for the radius from [tex]A=\pi r^2[/tex]. Then, tha radius is:
[tex]r=\sqrt{\frac{A}{\pi }}=\sqrt{\frac{254.47in^2}{\pi }} =9in[/tex]
Then, the circumference is:
[tex]C=2\pi (9in)=56.54in[/tex]

Find the y-intercept of each exponential function and order the functions from least to greatest y-intercept.
Answer:
1) g(x) ----> y-intercept -3
2) h(x) ----> y-intercept -1
3) f(x) ----> y-intercept 2
Step-by-step explanation:
we know that
The y-intercept or initial value, is the value of y when the value of x is equal to zero
Calculate the y-intercept of each exponential function
case 1) A function g, has a growth factor of 2 and a value of 1, and passes through the point (1,-2)
The exponential function is equal to
[tex]g(x)=1(2)^{x}+c[/tex]
Find the value of c
For x=1, g(x)=-2
substitute
[tex]-2=(2)^{1}+c[/tex]
[tex]-2=2+c[/tex]
[tex]c=-4[/tex]
so
[tex]g(x)=(2)^{x}-4[/tex]
Find the y-intercept
For x=0
[tex]g(0)=(2)^{0}-4[/tex]
[tex]g(0)=-3[/tex]
case 2) Observing the table
For x=0
f(0)=2
therefore
The y-intercept of f(x) is 2
case 3) Observing the graph
For x=0
h(0)=-1
therefore
The y-intercept of h(x) is -1
Order the functions from least to greatest y-intercept
1) g(x) ----> y-intercept -3
2) h(x) ----> y-intercept -1
3) f(x) ----> y-intercept 2
Final answer:
To find the y-intercept of an exponential function, evaluate it at x = 0. The constant term in the function represents the y-intercept. Order the functions by comparing these constant terms from least to greatest.
Explanation:
To find the y-intercept of an exponential function, we need to evaluate the function when x is equal to zero. The exponential function is usually given in the form f(x) =[tex]ab^x[/tex], where a is the y-intercept. This is because any number (except zero) raised to the power of zero is 1, so[tex]b^0[/tex] will always be 1, leaving us with f(0) = a.
After finding the y-intercept for each function, order them from least to greatest to complete the task. For example, if we have functions such as f(x) = [tex]2(3)^x, g(x) = 5(2)^x[/tex], and h(x) = [tex]-1(4)^x,[/tex] their y-intercepts would be 2, 5, and -1 respectively. Ordered from least to greatest, the functions by their y-intercepts would be h(x), f(x), g(x).

Four thousand students at a school were asked to name their favorite pizza topping. The results were 800 Pepperoni, 1,000 Sausage, 1,200 Mushrooms, 560 Peppers, 240 Onions, and 200 Other. Your friend expresses these results in this circle graph. Your friend made a mistake, however. What is wrong with his graph?
Answer:
The pepperoni and peppers are mixed up
Step-by-step explanation:
Answer:
The mistake my friend made was that pepperoni and peppers are mixed up, pepperoni is suppose to be 20% while peppers is supposed to be 14%
Step-by-step explanation:
Given that 4000 students
Pepperoni = 800
Sausage = 1,000
Mushrooms = 1,200
Peppers = 560
Onions = 240
Other = 200
To find the degree of each on the circle graph, we have:
Pepperoni = 800/4,000 * 100 = 20%
Sausage = 1,000/4,000 * 100 = 25%
Mushrooms = 1,200/4,000 * 100 = 30%
Peppers = 560/4,000 * 100 = 14%
Onions = 240/4,000 * 100 = 6%
Other = 200/4,000 * 100 = 5%
The mistake my friend made is that pepperoni and peppers are mixed up, pepperoni is suppose to be 20% while peppers is supposed to be 14%

Emilee signed a finance agreement for her purchase what is the total amount she will pay back under this agreement
To calculate the total amount Emilee will pay back under a finance agreement, one needs to know the specifics of the loan. Joanna's example, with a known interest rate and term, shows how to use the present value of an annuity formula to find out the maximum loan and total amount paid over time.
Explanation:The question pertains to calculating the total amount that Emilee will pay back under a finance agreement for her purchase. To determine this amount, one must know the principal amount of the loan, the interest rate, and the term of the loan.
For instance, if Joanna can afford to pay $12,000 a year for a house loan at an annual interest rate of 4.2% for 30 years, one can use the formula for the present value of an annuity to calculate the maximum loan she can afford. The formula is PV = PMT [1 - (1 + i)^(-n)] / i, where PV is the present value (the maximum loan), PMT is the annual payment ($12,000), i is the interest rate per period (4.2% annually), and n is the number of periods (30 years).
By applying this formula, Joanna can afford a maximum loan of approximately $202,556.98. Over 30 years, she will end up paying $12,000 times 30, which equals $360,000 in total. Similarly, to determine the total amount Emilee will repay, the same types of calculations would apply based on the terms of her finance agreement.

Your friend can clap his hands 28 times in 12 seconds. How many times can your friend clap his hands in 1.75 minutes?
Answer:
Step-by-step explanation:
12 seconds for 28 claps
1 second for (28/12) claps
? claps for 1.75 mins?
1.75 minutes = 105 seconds (1.75×60 = 105)
105 seconds for (28/12)×105 claps
= 245 claps
Answer:
Your friends can clap their hands 245 times in 1.75 minutes.
Step-by-step explanation:
First of all, you should know how many seconds represents 1.75 minutes, because the amount of applause your friends can make is in that measure of time. In order to make this conversion, a simple rule of three is made, knowing that 1 minutes is 60 seconds:
If 1 minute is 60 seconds, how many seconds are 1.75 minutes?
[tex]\frac{1.75minutes*60seconds}{1minute} =105 seconds[/tex]
Knowing that your friend can clap his hands 28 times in 12 seconds and knowing that 1.75 minutes is 105 seconds, you can perform a rule of three again:
If they can clap their hands 28 times in 12 seconds, how many applause can they make in 105 seconds?
[tex]\frac{105seconds*28applause}{12} =245 applause[/tex]
Then your friends can clap their hands 245 times in 105 seconds, which is 1.75 minutes.
Express the polynomial as a product of linear factors. 3x^3+12x^2+3x-18
Answer:
f(x) = 3(x + 2)(x - 1)(x + 3)
Step-by-step explanation:
A logical first step would be to factor 3 out of all four terms:
f(x) = 3x^3+12x^2+3x-18 = 3(x^3 + 4x^2 + x - 6)
Roots of this x^3 + 4x^2 + x - 6 could be factors of 6: {±1, ±2, ±3, ±6}.
I would use synthetic division here to determine which, if any, of these possibilities are actually roots of x^3 + 4x^2 + x - 6. Let's try x = 1 and see whether the remainder of this synth. div. is 0, which would indicate that 1 is indeed a root of x^3 + 4x^2 + x - 6:
1 / 1 4 1 -6
1 5 6
------------------------
1 5 6 0
Yes, 1 is a root of x^3 + 4x^2 + x - 6, and so (x - 1) is a factor of x^3 + 4x^2 + x - 6.
Look at the coefficients of the quotient, which are 1, 5 and 6.
This represents the quadratic 1x² + 5x + 6, whose factors are (x + 2) and
(x + 3).
Thus, the given polynomial in factored form is:
f(x) = 3x^3+12x^2+3x-18 = 3(x + 2)(x - 1)(x + 3)

four friends were born on consecutive years the sum of their ages is 62 what is the youngest friend
Answer:
The age of youngest friend = 14 years
Step-by-step explanation:
It is given that, four friends were born on consecutive years the sum of their ages is 62
Let 'x' be the age of youngest friend
age of other friends are (x + 1), (x + 2) and (x + 3)
To find the age of youngest friend
From the given information we can write,
x + (x + 1) + (x + 2) + (x + 3) = 62
4x + 6 = 62
4x = 62 - 6 = 56
x = 56/4 = 14
Therefore age of youngest friend = 14
