A repairman charges an inspection fee plus $16 per hour. A customer with a coupon for 30% off the inspection fee pays $74 for a 2-hour repair. How many hours are worked when a customers pays $124 without a coupon?
Answer:
I want to say that the hours worked was 4. I hope that is right.
Step-by-step explanation:
30% off of $60 is 42
16*2=32 and 32+42=74
124-60=64
16*4=64
so he would have worked 4 hours for $64 and a fee of $60
64+60= 124

Plz Help due in 10 min If triangle ABC has the following angle measurements, what is the value of x?
∠A=4x − 17
∠B= 3x + 8
∠C= x+ 13
x = 22
x = 23
x= 176
x = 3.7
Answer:
Step-by-step explanation:
4x-17+3x+8+x+13=180
8x+4 =180
8x=176
X=22
Answer:
x = 22
Step-by-step explanation:
<A + <B + <C = 180
<A = 4x - 17
<B = 3x + 8
<C = x + 13
4x - 17 + 3x + 8 + x + 13 = 180 Collect the like terms
8x + 4 = 180 Subtract 4 from both sides
8x = 180 - 4
8x = 176 Divide by 8
x = 176/8
x = 22
-3x-5<10 Equations
Answer:
x>-5
Step-by-step explanation:
First, we need to isolate the variable. To start doing this we can add five to both sides. We now have -3x<15. We then have to divde by -3. When working with inequalites you flip the inequality sign when dividing by a negative number. That then leaves us without answer, x>-5.
Find the mean of the following set of numbers:
8.9, 6.1, -4.8, 8.2, 2.7,-0.1
Enter the answer
Answer:
The mean of the given set of numbers is 3.5
Step-by-step explanation:
We need to find the mean of following numbers:
8.9, 6.1, -4.8, 8.2, 2.7,-0.1
For calculating the mean the formula used is: [tex]Mean=\frac{Sum \ of \ all \ numbers}{Total \ numbers}[/tex]
Finding sum of numbers:
[tex]Sum \ of \ numbers= 8.9+6.1-4.8+8.2+2.7-0.1\\Sum \ of \ numbers= 21[/tex]
Total numbers = 6
So, mean is:
[tex]Mean=\frac{Sum \ of \ all \ numbers}{Total \ numbers}\\Mean=\frac{21}{6}\\Mean= 3.5[/tex]
So, mean of the given set of numbers is 3.5

At a party there are 3 pizzas to share. If each pizza has 8 slices, determine how many pieces each child will receive if 12 kids attend the party. Now what if 8 kids attend?
Answer: your answer is 3
Step-by-step explanation: if you multiply 3 and 8 you get 24 divide that by 8.
The number of pizzas each kid will receive if there were 12 children was 2 slices each
The number of pizzas each kid will receive if there were 8 children was 3 slices each
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The total number of pizzas at the party = 3 pizzas
The total number of slices in 1 pizza = 8 slices
So , the number of slices in 3 pizzas = 3 x 8 slices
The number of slices in 3 pizzas = 24 slices
Now , the equation will be
The number of children attended the party be = A
The value of A = 12 children
So , the number of pizza slices each child gets = number of slices in 3 pizzas / number of children attended the party
Substituting the values in the equation , we get
Number of pizza slices each child gets = 24 / 12
Number of pizza slices each child gets = 2 slices each
Therefore , if there are 12 children , the number of slices of pizzas each child receives is 2 slices
Now , if the number of children is B = 8
Number of pizza slices each child gets = 24 / 8
Number of pizza slices each child gets = 3 slices each
Therefore , if there are 8 children , the number of slices of pizzas each child receives is 3 slices
Hence , The number of pizzas each kid will receive if there were 12 children was 2 slices each
The number of pizzas each kid will receive if there were 8 children was 3 slices each

The quadratic [tex]3x^2+4x-9[/tex] has two real roots. What is the sum of the squares of these roots? Express your answer as a common fraction in lowest terms.
Answer:
70/9
Step-by-step explanation:
We have the quadratic:
[tex]3x^2+4x-9[/tex]
So, let’s find the roots of the quadratic. We will set the expression equal to 0:
[tex]3x^2+4x-9=0[/tex]
Testing for factors, we can see that our quadratic isn’t factorable.
So, we can use the Quadratic Formula. The quadratic formula is given by:
[tex]\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
In this case:
[tex]a=3, b=4,\text{ and } c=-9[/tex]
Therefore, by substitution:
[tex]\displaystyle x=\frac{-(4)\pm\sqrt{(4)^2-4(3)(-9)}}{2(3)}[/tex]
Evaluate:
[tex]\displaystyle x=\frac{-4\pm\sqrt{124}}{6}[/tex]
Simplify the square root:
[tex]\sqrt{124}=\sqrt{4\cdot31}=2\sqrt{31}[/tex]
Hence:
[tex]\displaystyle x=\frac{-4\pm2\sqrt{31}}{6}[/tex]
Reduce:
[tex]\displaystyle x=\frac{-2\pm\sqrt{31}}{3}[/tex]
So, our roots are:
[tex]\displaystyle x_1=\frac{-2+\sqrt{31}}{3}, x_2=\frac{-2-\sqrt{31}}{3}[/tex]
We want to find the sum of the squares of our two roots. So, let’s square each term:
[tex]\displaystyle (x_1)^2=\Big(\frac{-2+\sqrt{31}}{3}\Big)^2[/tex]
Square. For the numerator, we can use the perfect square trinomial patten where:
[tex](a+b)^2=(a^2+2ab+b^2)[/tex]
Therefore:
[tex]\displaystyle (x_1)^2=\Big(\frac{(-2)^2+2(-2)(\sqrt{31})+(\sqrt{31})^2}{9}\Big)[/tex]
Simplify:
[tex]\displaystyle (x_1)^2=\frac{35-4\sqrt{31}}{9}[/tex]
Similarly, for the second root, we will have:
[tex]\displaystyle (x_2)^2=\Big(\frac{-2-\sqrt{31}}{3}\Big)^2[/tex]
So:
[tex]\displaystyle (x_2)^2=\Big(\frac{(-2)^2+2(-2)(-\sqrt{31})+(-\sqrt{31})^2}{9}\Big)[/tex]
Simplify:
[tex]\displaystyle (x_2)^2=\frac{35+4\sqrt{31}}{9}[/tex]
Therefore, our sum will be:
[tex]\displaystyle (x_1)^2+(x_2)^2\\\\ \begin{aligned} &=\frac{35-4\sqrt{31}}{9}+\frac{35+4\sqrt{31}}{9}\\&=\frac{35-4\sqrt{31}+35+4\sqrt{31}}{9}\\&=\frac{70}{9}\end{aligned}[/tex]
Therefore, our final answer is 70/9.

Find all possible values of b such that 4x^2+bx+3 can be factored?
Answer:13,7,8 but if there’s an answer choice go with 7,8
Step-by-step explanation: Assuming b is an integer, we first look at factors of 4, being 1 and 4 or 2 and 2. The factors of 3 are 1 and 3 only. So the factorisation possibilities are (x+3)(4x+1), (4x+3)(x+1) and (2x+1)(2x+3).
Expanding these we get: 4x²+13x+3, 4x²+7x+3 and 4x²+8x+3, giving values of b=13, 7 and 8
The possible values of b in the given polynomial are 7, 8 or 13.
What is a polynomial?In mathematics, a polynomial is an expression consisting of indeterminates (also called variables) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer powers of variables.
Given is a polynomial, 4x²+bx+3, we need to find all possible values of b such that 4x²+bx+3 can be factored.
4x²+bx+3
4×3=2×2×3
2×2×3 = 2×6 and 2+6 = 8
2×2×3 = 4×3 and 4+3 = 7
2×2×3 = 12×1 and 12+1 = 13
b=7, b=8, and b=13
4x²+7x+3 = (4x+3) (x+1)
4x²+8x+3 = (2x+1) (2x+3)
4x²+13x+3 = (4x+1) (x+3)
Hence, the possible values of b in the given polynomial are 7, 8 or 13.

Write a linear function f with the values f(-4) = 0 and f (4) = 2.
Answer:
y + (1/4)(x + 4)
Step-by-step explanation:
One point on the graph is (-4, 0); another is (4, 2).
The change in x from the first point to the second is 8; this is the 'run.'
The change in y is 2 (which is 2 - 0). This is the 'rise.'
Thus, the slope of the line is m = rise / run = 2/8 = 1/4
Let's use the point-slope form of the equation of a straight line:
y - k = m(x - h). Substituting 0 for k and -4 for h, we get:
y - 0 = (1/4)(x + 4), or
y + (1/4)(x + 4)

Dave is making cookies.
He mixes flour, butter and sugar in the ratio 6:4:1
Dave uses 160 grams of butter.
Work out how much flour and sugar Dave uses.
Answer: 240 grams of flour and 40 grams of sugar.
Step-by-step explanation: I used the rule of three to calculate the values for the flour and sugar. The common ratio that these numbers have would
be 40.
Reasoning: If the ratio is 6:4:1, then you can apply it as a rule of three. If 160 relates to 4, then x (the value of flour) will relate to 6. 160/4 = x/6, cross multiply, and x = 240. The amount of flour is 240 grams. Using the same logic, you can set another rule for the amount of sugar (represented by variable s); 160/4 = s/1. Cross multiply, and s = 40. The amount of sugar is 40 grams.

Natalie and John are both saving coins in jars for a rainy day. Natalie currently has 1 1/8 jars of coins, and John has 9/14 of a jar of coins. If John gets all his coins to Natalie, how many jars of coins would she have all together?
Answer:
Natalie will have [tex]1\frac{43}{56}[/tex] jars of coins all together after receiving John's coins.
Step-by-step explanation:
Given that:
Coins Natalie have = [tex]1\frac{1}{8}[/tex] jars of coins
Coins John have = [tex]\frac{9}{14}[/tex] jars of coins
When John will give all his coins to Natalie.
Total coins Natalie have = Her coins + John's coins
Total coins Natalie have = [tex]1\frac{1}{8}+\frac{9}{14}[/tex]
Total coins = [tex]\frac{9}{8}+\frac{9}{14}[/tex]
Total coins =[tex]\frac{63+36}{56}=\frac{99}{56}[/tex]
Total coins = [tex]1\frac{43}{56}[/tex]
Hence,
Natalie will have [tex]1\frac{43}{56}[/tex] jars of coins all together after receiving John's coins.
