Answer:
20%
Step-by-step explanation:
First, add 1,200, and 300. That gives you 1,500. You want to find how much percent of 1,500 equals 300, and that is 20%.
Answer:
25%
Step-by-step explanation:
1. You have a total of 1,200 students and a fraction of them did not wear their school colors, 300 students.
2. You would write the fraction [tex]\frac{300}{1200}[/tex].
3. After you divide or simpify [tex]\frac{300}{1200}[/tex] you get [tex]\frac{1}{4}[/tex].
4. To get a percent you multiply by 100, so [tex]\frac{1}{4}[/tex] times 100 is equal to 25.

Answer:
r = -14
Step-by-step explanation:
22 = r/7 + 24 <-- try and isolate r
22-24 = r/7
-2 = r/7
-2(7) = r
r = -14
Answer:
-14
Step-by-step explanation:
subtract 24 on both sides
-2=r/7
-14=r
What is the perimeter of the rectangle?

Answer:
220
Step-by-step explanation:
perimeter is the sum of all sides
p= 60+60+50+50
p=220
Step-by-step explanation:
Perimeter = 2(length *width)
[tex]2(50 + 60) \\ \\ = 2 \times 110 \\ \\ = 220[/tex]
Angle QRS has a measure of 35°. Triangle QRS is rotated 90° clockwise about point R to create angle Q'R'S. What is the measure of angle Q'R'S?
PLEASE ANSWER URGENT
Answer:
The measure of angle Q'R'S' is 35°
Step-by-step explanation:
The given parameters are;
The measure of angle QRS = 35°
The transformation applied to triangle QRS = 90° clockwise rotation
For a 90° clockwise rotation, we have;
Coordinate of the preimage (x, y), coordinate of the image after rotation (y, -x)
Given that the distance, d, between points is given by √((x₂ - x₁)² + (y₂ - y₁)²), we have that the distance between points of the image will be given as follows;
d' =√((y₂ - y₁)² + ((-x₂) - (-x₁))²) = √((y₂ - y₁)² + (x₁ - x₂)²)
Whereby we have √((y₂ - y₁)² + (x₁ - x₂)²) = √((x₂ - x₁)² + (y₂ - y₁)²)
Therefore, d = d' and the length of the sides and measures of the angles in ∠QRS and ∠Q'R'S' will be equal and ∠Q'R'S' = ∠QRS = 35°.

Answer:
B.) -4
Step-by-step explanation:
y=mx+b
b is equal to the y-intercept.
Answer:
-4
Step-by-step explanation:
The slope intercept form is y = mx + b.
m = slope
b = y-intercept
since b = -4, the y-intercept is -4

Step-by-step explanation:
Austin is planning a canoe trip with his dad and brother. They are taking a cooler and a few supplies that weigh a total of 89 pounds with them. The canoe has a maximum weight limit of 765 pounds. Which inequality can be used to find , the average allowable weight in pounds for each person in the canoe?
A. 3p - 89 > 765
B. 3p - 89 765
C. 3p + 89 > 765
D. 3p + 89 < 765
Answer:
3p + 89 < 765
Correct answer: D.
Step-by-step explanation:
Austin, his dad, and brother make a group of three people of varying weights. Assume their average weight is p and their total weight 3p.
The cooler and other supplies weigh 89 pounds in total.
The weight of the supplies and the three people in the canoe should not be equal or exceed the maximum allowable weight of the canoe of 765 pounds.
This leads to inequality:
3p + 89 < 765
Correct answer: D.
Solve the equation
x2 + 4x - 7 = 0
by completing the square.
Give your answers correct to 2 decimal places.
Answer:
x ≈ 1.32, x ≈ - 5.32
Step-by-step explanation:
Given
x² + 4x - 7 = 0 ( add 7 to both sides )
x² + 4x = 7
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(2)x + 4 = 7 + 4
(x + 2)² = 11 ( take the square root of both sides )
x + 2 = ± [tex]\sqrt11}[/tex] ( subtract 2 from both sides )
x = - 2 ± [tex]\sqrt{11}[/tex]
Thus
x = - 2 - [tex]\sqrt{11}[/tex] ≈ - 5.32 ( to 2 dec. places )
x = - 2 + [tex]\sqrt{11}[/tex] ≈ 1.32 ( to 2 dec. places )

-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.
I hope that this helps! :)
What is the slope of the line that contains the points (-2, 2) and (3, 4)?
A.
O B. -
O c.
OD.
Answer: m = 2/5
Step-by-step explanation:
The formula for the slope is m = rise over run = y^2 - y^1 / x^2 - x^2
which makes it 4-2 over 3-(-2) which equals 2/5
Youre answer is 2/5
Answer:
The slope of the line that contains the points (-2, 2) and (3, 4) is 2/5.
Step-by-step explanation:
The slope of a line is denoted by m and is calculated using the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Here
[tex](x_1,y_1)[/tex] are the coordinates of the first point on line and
[tex](x_2,y_2)[/tex] are the coordinates of the second point on line
Given two points are:
(x1,y1) = (-2, 2)
(x2,y2) =(3, 4)
Putting the values in the formula
[tex]m = \frac{4-2}{3-(-2)}\\m = \frac{2}{3+2}\\m=\frac{2}{5}[/tex]
Hence,
The slope of the line that contains the points (-2, 2) and (3, 4) is 2/5.

Alabama has 140 legislators, for 4 million people. If another state has 12 million people living in it, how many legislators would it have? How do you know?
Answer: 420 legislators
Step-by-step explanation:
For this problem, we would have to multiply.
If Alabama has 140 legislators for 4 million people, we know the unit rate is:
[tex]140[/tex] legislators for [tex]4[/tex] million people.
So, we have to multiply 140 by 3 because 12 is 3 times the amount of 4, and the other state has 12 million people.
140 x 3 = 420
The answer to the question would be 420.
Answer:
420
Step-by-step explanation:
I set this up as a proportion of 140/4,000,000=x/12,000,000. Then you can cross multiply, getting 1,680,000,000=4,000,000x. Divide both sides by 4,000,000 and you get x=420. Please mark brainliest if this helped!

Find the value of c that completes the square
x^2-16x+c
Please help me with how to do this, and show me. Thank you.
Answer:
The value that completes the square is: c=8
Step-by-step explanation:
Find the value of c that completes the square [tex]x^2-16x+c[/tex]
The formula used is: [tex]a^2-2ab+b^2=(a-b)^2[/tex]
In the question given the value c can be found by breaking the middle term. we are given -16x while the general formula is 2ab for middle term so,
2(x)(8) = 16x
so, c= 8
Solving:
[tex]x^2-16x+c\\=x^2-2(x)(8)+(8)^2-(8)^2\\=(x-8)^2-64[/tex]
So, the value that completes the square is: c=8

Step-by-step explanation:
A company announces that it will be giving $4,200 of its profits to charity. If the company profits 28,000 what percent will the company give to charity
Given:
Company profits = $28,000
Charity = $4200
To find:
The percent that will the company give to charity.
Solution:
We have,
Company profits = $28,000
Charity = $4200
Now,
[tex]Charity\%=\dfrac{Charity}{Profit}\times 100[/tex]
[tex]Charity\%=\dfrac{4200}{28000}\times 100[/tex]
[tex]Charity\%=\dfrac{420}{28}\times 1[/tex]
[tex]Charity\%=15\%[/tex]
Therefore, the company will give 15% of its profit to charity.
