7. What number is 32% of 79?
A.n= 32.79: 2.528
B.32 = n. 79: 0.4
C.79=n.0.32: 246.9
D.n-0.32.79; 25.3
Answer:
If they're asking you to round, I'll choose D just because 25.28 is 25.3 rounded to the nearest tenth.
Step-by-step explanation:
79/x=100/32
(79/x)*x=(100/32)*x - we multiply both sides of the equation by x
79=3.125*x - we divide both sides of the equation by (3.125) to get x
79/3.125=x
25.28=x
x=25.28
Simplify.

Determine whether the graph could be the graph of a polynomial function. If it could be lost the real zeroes and states the least degree the polynomial can have.
Answer:
the graph is of a cubic function.
Step-by-step explanation:
f(x)= x^3. It should have at least one zero
The graph shows cubic polynomial.
What are Polynomial?A polynomial is an equation that solely uses the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are also known as indeterminates.
Given:
In the graph the number of times the graph touches the x- axis it will have that many zeroes or solution for the polynomial.
The given graph touches the x-axis three times which shows the polynomial will have three solution and the degree of the polynomial is 3.
Hence, the graph shows cubic polynomial.

i really need help!!!! i need answer to c:
Answer:
76.3
Step-by-step explanation:
Answer:
C = 75°
Step-by-step explanation:
The interior angles of a triangle will always add up to 180°, so all we have to do is find the missing variable.
To do this, we first add up the two angles we do know.
—> 65 + 40 = 105
Now that we have the total of the other two angles, simply subtract 105 from 180.
—> 180 - 105 = 75
We now have our answer!

-6a +3 =-3(2a-1) question number 2
Answer:
D. identity
Step-by-step explanation:
- 6a + 3 = - 3(2a - 1)
First, distribute -3 within the parenthesis.
- 6a + 3 = - 6a + 3
Subtract 3 from both sides of the equation
- 6a = - 6a
Divide - 6 on both sides of the equation
a = a
We know because both sides have the same equation, and that it is true, that this equation has infinite solutions, so the answer would be D. Identity
For those who don't know, identity in algebra means that the equation is true no matter what is substituted in for the variable. It will always be true.

Find the area of this trapezoid. Be sure to include the correct unit in your answer.
graph y = 4x-9 please
Step-by-step explanation:
Just take two random points, always remember ,take x=0 and find his correspondent y
in this case y=4*0-9=-9
first point (0,-9)
second one:
take any x you want, I took 2 randomly, and y will be
y=4*2-9=8-9=-1
second point is (2,-1)
find these points on graph and connect them with a ruler ! And that is the line you are searching for!
We want to graph the line y = 4*x - 9.
The graph can be seen at the end of the answer.
To graph a given linear function, we need to find two points that belong to the function, and then connect them with a line.
To find the points we just evaluate the function in two different values of x, so let's do that.
For x = 0 we have:
y = 4*0 - 9 = -9
Then we have the point (0, -9)
For x = 1 we have:
y = 4*1 - 9 = 4 - 9 = -5
Then we have the point (1, -5)
Now we just can graph these two points on a coordinate axis, and connect them with a line.
The graph is shown below

sorry :(
Hopefully someone fills in the rest of the answers!!!
Answer:
Question 1:
8/12 = 4/6 = 3/x
0.6 = 0.6 = 3/x
It is a similar triangle, therefore 3/x = 0.6
x = 5 because 3/5 = 0.6
Question 2
You did that correct :)
Question 3:
"Check all that apply"
B
D
Question 4
You got question 4 wrong since similar triangles have similar ratio.
8/10 = 8/10 = 10/14
0.8 = 0.8 = 0.7
Correct answer for question 4 is B("No they are not similar because the ratios are not equal")
Question 5
The Quadrilaterals are similar. Therefore:
22.4/14 = 12.8/8 = 12/7.5 = 26/x
1.6 = 1.6 = 1.6 = 26/x
Meaning 26/x = 1.6
x = 16.25
Because 26/16.25 = 1.6

Given:
There are 4 quarts in a gallon.
She wants to convert 6 quarts to a gallon.
To find:
Whether she should multiply 6 by 4 or divide 6 by 4 to find her answer.
Solution:
We have,
[tex]4\text{ quarts}=1\text{ gallon}[/tex]
[tex]1\text{ quarts}=\dfrac{1}{4}\text{ gallon}[/tex]
[tex]6\text{ quarts}=\dfrac{6}{4}\text{ gallon}[/tex]
Here, 6 quarts is equal to [tex]\dfrac{6}{4}[/tex] gallon. It means we need to multiply 6 by 4 in [tex]4\text{ quarts}=1\text{ gallon}[/tex] to find the answer.
