Answer:
32
Step-by-step explanation:
4(5+3)=
20+12=
32
or
4(5+3)=
4(8)=
32
The answer is 32.
5 + 3 is 8, and since the 8 is in parenthesis, we multiply it by the 4 on the outside.

7/13 of the population of a town is female.of the males 2/3 are married,What fraction population consists of unmarried men?
Answer:
Step-by-step explanation:
[tex]\frac{7}{13}[/tex]-Female
[tex]\frac{2}{3}[/tex]- Men Married.
[tex]\frac{7}{13} divided by \frac{2}{3} = \frac{7}{13} x\frac{3}{2} = \frac{21}{6} = 3\frac{2}{6} = 3\frac{1}{3}[/tex]

i got it correct:)
Answer:
Other guy is correct
Step-by-step explanation:
Power of a product: When a product is raised to a power, each factor is raised to the power separately.
Power of a power: When an exponential expression is raised to a power, multiply the exponents.
Product of powers: When two exponential expressions with the same base are multiplied, add the exponents.
Quotient of powers: When two exponential expressions with the same base are divided, subtract the exponents.
Power of a quotient: When a quotient is raised to a power, raise the dividend and the divisor to the power separately.

Answer:
10/16
Step-by-step explanation:
I looked at the 5 and looked at every other number and you can't multiply evenly with those other numbers. You can only do 5x2 which will get you ten. But that won't work for the other numbers.

Luke is having a popsicle and chips for a snack. There are four popsicles in the freezer: two are cherry, one is orange, and one is grape. There are also two bags of Doritos and three bags of Cheetos in the basket. If he reaches into the freezer to get a popsicle without looking, what is the probability Luke will choose a cherry popsicle?
Answer:
50%
Step-by-step explanation:
Sense there are 4 popsicles in all, and 2 are cherry, there would be 2/4 cherry popsicles, which is 1/2 or 50%
Hope my explanation makes sense :)
8.Rewrite the expression using rational exponents.
Answer:
Option B is the correct option.
Step-by-step explanation:
Given the expression
[tex]\frac{\sqrt[3]{x^5}}{\sqrt[3]{x^7}}[/tex]
Apply radical rule:
[tex]\frac{\sqrt[n]{a}}{\sqrt[n]{b}}=\sqrt[n]{\frac{a}{b}}[/tex]
so
[tex]\frac{\sqrt[3]{x^5}}{\sqrt[3]{x^7}}=\sqrt[3]{\frac{x^5}{x^7}}[/tex]
Apply radical rule:
[tex]\frac{x^a}{x^b}=x^{a-b}[/tex]
so
[tex]=\sqrt[3]{\frac{1}{x^2}}[/tex] ∵ [tex]\frac{x^5}{x^7}=x^{5-7}[/tex]
[tex]=\frac{1}{x^{\frac{2}{3}}}[/tex]
Therefore, option B is the correct option.
Your sister wants to make more cookies and decides to use 4 cups of sugar. She says that she will need
to use 3 1/2% cups of flour. Do you agree with her? Explain your reasoning.
An employer has three employees who are each paid a salary of $1,250 per month. He wants to give each of the three employees a $125 per month raise and he wants to hire an additional salaried employee. If his salary budget for these employees is $5,325 per month, how much can he afford to offer the new employee?
Step-by-step explanation:
1,250+125= 1,375
1375×3=4125
5325-4125=1200
They can afford to play the new employee $1200

I need help with these questions for Working with Standard and Vertex Forms of the Quadratic Function, the first image is the instructions for the questions and the rest of the images have been labelled and put in order of the questions:

Answer:
3 (7e) f(x) = -3(x +2)^2 +1; D: (-∞, ∞); R: (-∞, 1]
4 (8) g(x) = 4(x -3)^2 -5; x = 3; (3, -5); min: -5; D: (-∞, ∞); R: [-5, ∞)
5 (10) A(175) = 31,250 m^2
Step-by-step explanation:
Q3. (7e) f(x) = -3x^2 -12x -11 = -3(x^2 +4x) -11 = -3(x^2 +4x +4) -11 +3(4)
f(x) = -3(x +2)^2 +1
Domain: all real numbers; Range: y ≤ 1
Expanded: -3(x^2 +4x +4) +1 = -3x^2 -12x -11
__
Q4. (8a) g(x) = 4(x^2 -6x) +31 = 4(x^2 -6x +9) +31 -4(9)
g(x) = 4(x -3)^2 -5
8b) x = 3 . . . axis of symmetry
8c) (3, -5) . . . coordinates of vertex
8d) minimum: -5 (parabola opens upward from vertex, which is the minimum)
8e) any quadratic has a domain of "all real numbers"
8f) the range is upward from the minimum: y ≥ -5
8g) see attached
__
Q5. (10) A(x) = 700x -2x^2 = -2(x^2 -350x +30625) +2(30625)
A(x) = -2(x -175)^2 +31,250

The process of "completing the square" can be done using the following steps. (a) Factor out the leading coefficient from the variable terms; (b) determine the linear term coefficient inside parentheses, and add the square of half of it inside parentheses; (c) add the opposite of the same quantity outside parentheses (make sure the leading coefficient is properly factored in; (d) rewrite the parentheses as a square, and collect terms outside parentheses. In the final form a(x -h)^2 +k, the vertex is (h, k).
A plane starts at the origin of the coordinate plane. The plane fly 0.5 units left and 3.5 units up to point X. What are the coordinates of point X?
Answer:
A. -3.5, 0.5
Step-by-step explanation:
This is because the coordinates are saying they are located on quadrant ll so the x coordinate has to be a negative and the y coordinate has to be positive

Answer:
x=3/4+1/4√37 or x=3/4+−1/4√37Step-by-step explanation:
Let's solve your equation step-by-step.
−2x−5=2−4x(x−1)
Step 1: Simplify both sides of the equation.
−2x−5=−4x^2+4x+2
Step 2: Subtract -4x^2+4x+2 from both sides.
−2x−5−(−4x^2+4x+2)=−4x^2+4x+2−(−4x^2+4x+2)
4x^2−6x−7=0
For this equation: a=4, b=-6, c=-7
4x^2+−6x+−7=0
Step 3: Use quadratic formula with a=4, b=-6, c=-7.
x=−b±√b2−4ac/2a
x=−(−6)±√(−6)2−4(4)(−7)/2(4)
x=6±√148/8
