If she is setting up a proportion to find the percent, the value of m would be any variable and the value of n would be 100. When she solves the problem, m=65%.
13/20 is part out of whole. The rest of the proportion will be "percent out of 100"; since we don't initially know the percent, we use a variable. Thus we have
13/20 = m/100
Cross multiply:
20*x = 13*100
20x = 1300
Divide both sides by 20:
20x/20 = 1300/20
x = 65
evaluate function expression 5xf(1) + 5xg(9)
Answer:
5x(f+9g)
Step-by-step explanation:
5xf(1)+5xg(9)
Factor out 5.
5(xf+9xg)
Consider xf+9xg. Factor out x.
x(f+9g)
Rewrite the complete factored expression.
5x(f+9g)

Answer:
I think 235.5 mm cubed
Step-by-step explanation:
The formula for the volume of a cone is V=1/3hπr².
1/3 x 9 x π x 5² =
1/3 x 9π x 25 =
1/3 x 225π =
75π
let's say π=3.14
75 x 3.14 = 235.5

Talia grouped the terms and factored out the GCF of the groups of the polynomial 15x2 – 3x – 20x + 4. Her work is shown below.
(15x2 – 3x) + (–20x + 4)
3x(5x – 1) + 4(–5x + 1)
Talia noticed that she does not have a common factor. What should she do?
Talia needs to leave the polynomial as is because it is prime and cannot be factored.
Talia needs to group the terms differently.
Talia needs to factor out a negative from one of the groups so the binomials will be the same.
Talia needs to apply the distributive property to get the expression (3x + 4)(5x – 1).
Answer:
Talia needs to factor -1 out of one of the two binomials
Step-by-step explanation:
She could take:
3x(5x - 1) + 4(-5x + 1)
and rewrite it as:
3x(5x - 1) - 4(5x - 1)
= (3x - 4)(5x - 1)

The cube root of a number is 2. Write an equation, using x, that represents this situation.
Answer:
x - 8 = 0
Step-by-step explanation:
Since, the cube root of a number is 2.
Let the number be x.
Therefore,
[tex] \sqrt[3]{x} = 2 \\ cubing \: both \: sides \\ {( \sqrt[3]{x})}^{3} = {(2)}^{3} \\ x = 8 \\ x - 8 = 0[/tex]
You and a friend go to Tacos Galore for lunch. You order three soft tacos and five burritos and your total bill is $17.75. Your friend orders four soft tacos and two burritos and paid $12.00.
Answer:
Step-by-step explanation:
let tacos be x and burritos be y
so, your 1st eqn. is 3x + 5y = 17.75
2nd eqn. is 4x+ 2y = 12
Solving the 2 eqns: Multiply eqn 1 with 2 and eqn 2 with 5
So: 6x+10y=35.5
-20x-10y=-60
=-14x=-24.5
x=24.5/14 = 1.75
Substituting the value of x in eqn 1 : (3*1.75)+5y=17.75
y = 2.5

Angle C is 90 degrees so angle A and B are both the same length I think.
Since 180 degrees is the total because it is a triangle, then 180-90=90/2=?
Plz answer....,.......................
Answer:
B and C
Step-by-step explanation:
Not A because the side lengths aren't multiples.
Not D because it would be congruent, unless it had different angles, but then similar shaps must have the same angles
Good luck <3
What angle measure is represented by the shaded part of
the circle? Explain how you found your answer.
Answer:
135degree
Step-by-step explanation:
First we see on the diagram all sectors are equal
so the sectors can be determined by X
there are 8 sectors all the interior angle of circle is 360 degree
so 8x =360
x=45degree
but their are 3shaded regions so
3x= 135degree

Answer:
y/-3 = 1/6
y = 1/6 × 3
y = 0.5
Answer:
-1/2 and -0.5
Explanation :
Hey! Ok so you will plug in all the value in the y to find out if it equals to 1/6.
y ÷ -3 = 1/6
0.5 ÷ -3 = 1/6
-1/6 = 1/6 ---> NO
y ÷ -3 = 1/6
-1/2 ÷ -3 = 1/6
1/6 = 1/6 ---> YES
y ÷ -3 = 1/6
-0.5 ÷ -3 = 1/6
1/6 = 1/6 ---> YES
y ÷ -3 = 1/6
-18 ÷ -3 = 1/6
6 = 1/6 ---> NO

A right cone has a slant height of 6 and a radius of 4. What is its surface
area?
A. 40 units^2
B. 56 units^2
C. 24 units^2
D. 16 units^2
The surface area of the cone is 16π square units.
What is the surface area of the cone?The surface area of the cone is given by;
⇒ Area = πrl + πr²
Here, We have;
A right cone has a slant height of 6 and a radius of 2.
Substitute all the values in the formula
⇒ Area = πrl + πr²
⇒ Area = π x 2 x 6 + π x 2²
⇒ Area = 16π
Hence, The surface area of the cone is 16π square units.

Making this problem into a proportion we get:
6/$15 = x/$10
Cross multiply 10 and 6, we get 60. Now divide that by 15, you get 4.
4/3 (3x-12)=2x+8 what is x
The answer is, X = 12.
hope it helps.
Answer:
x = 12
Step-by-step explanation:
simlify 4/3 * (3x-12)
4x - 16 = 2x + 8
combine like terms, so subtract 2x by 4x
2x - 16= 8
then finish combining like terms, so 16 plus 8
2x = 24
divide 24 by 2
x = 12
