To make a shade of paint called jasper green, mix 4 quarts of green paint with 53 cups of black paint. Select an equation that calculates how quarts of green paint, , are mixed with a given amount of black paint, .
Answer:
g = 12b /5
Step-by-step explanation:
Given that:
Quarts of green paint = 4
Cup of black paint = 5/3
Quartz of green paint to be mixed with a given proportion of black paint.
Let proportion of black paint = b
Quartz of green paint = g
4 quartz = 5/3 cups
g quartz = b
Cross multiply :
4 * b = (5/3) * g
5/3 * g = 4b
g = 4b ÷ 5/3
g = 4b * 3/5
g = 12b /5

At an online bookstore, Alicia downloads 3 books for $9 each and 2 magazines for $4 each. She uses a $50 gift card to pay for the books. Write an expression that shows how she can figure out how much money is left on the card after making the purchases.
Answer:
$15
Step-by-step explanation:
So first we see that alicia buys 3 books for $9 and that would be 27 because 3x9=27. Now we also see that she bought 2 magazines for $4 and that would be 8 because we are multiplying 4x2. Now we add 27 and 8 which would give us 35. She uses a $50 card to make the purchase. We subtract, 50-35 and we would get 15. So alicia has $15 left on the card.

Ryan made 70% of the basketball shots he attempted if he made 63 baskets how many shots did he attempt
Answer:
Ryan attempted 90 shots
Step-by-step explanation:
63 is 70% of 90
90 x .7 = 63
Ryan attempted 90 shots and 63 of them are baskets which is 70 percent.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, Ryan made 70% of the basketball shots he attempted.
let, 'x' be the number of shots he attempted and 63 of them are baskets.
So, 70% of x is 63, which is,
(70/100)×x = 63.
0.7x = 63.
x = 63/0.7.
x = 90.
So, Ryan attempted 90 shots in total.

A carpenter is making a backyard deck. In the measurements, he has determined that he needs to make a support triangle with an area of 22m2. He knows that the base must be 1 less than 3 times the height. If the base is represented by 3x-1 and height equals x. Find the equation that correctly shows the area of the triangle.
Group of answer choices
1/2x(3x - 1) = 11
x(3x -1) = 11
x(3x - 1) = 22
1/2x(3x - 1) = 22
Answer:
Base=3x-1
height =x
As we know that in a triangle
[tex]{\boxed{\sf Area={\dfrac {1}{2}}\times Base \times Height }}[/tex]
Substitute the value[tex]\qquad\quad {:}\longrightarrow\sf 22={\dfrac {1}{2}}(3x-1)(x)[/tex]
[tex]\qquad\quad {:}\longrightarrow\sf x (3x-1)=44 [/tex]
[tex]\qquad\quad {:}\longrightarrow\sf 3x^2-x=44 [/tex]
Correct option is option DThe equation that correctly shows the area of the triangle is 1/2x(3x - 1) = 22. Correct option is d.
To find the equation that correctly shows the area of the triangle, we use the formula for the area of a triangle:
Area = (1/2) * base * height
Given that the base is represented by 3x - 1 and the height is x, the area of the triangle is:
Area = (1/2) * (3x - 1) * x
Now, we are given that the area of the triangle is 22m^2:
(1/2) * (3x - 1) * x = 22
To solve for x, we can multiply both sides by 2 to eliminate the fraction:
2 * (1/2) * (3x - 1) * x = 2 * 22
x * (3x - 1) = 44
Now, we have the equation that correctly shows the area of the triangle:
x(3x - 1) = 44
So, the correct answer is:
x(3x - 1) = 44

Rectangle PQRS is dilated by a scale factor of 2 (k=2) with the origin as the center. What are the coordinates of R('?
A) R'(8,2)
B) R'(1, 1/4)
C) R'(6,3)
D) R'(2,8)
Answer:
Correct Answer: (8,2)
Step-by-step explanation:
Dilation about the origin
Most dilations in the coordinate plane use the origin, (0,0), as the center of the dilation.
In such cases, every point (x,y) dilated by a factor of k is mapped to the point (kx,ky).
The point R=(4,1) is dilated by a scale factor of 2 (k=2), thus the coordinates of its image are (2*4,2*1) = (8,2)

write an equation in slope-intercept of the line shown. (3,1), (1,-3)
Answer:
y=2x-5
Step-by-step explanation:
Answer and explanation is in the picture.
The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
The equation of the line that passes through the point (3, 1) and (1, -3) is
y = 2x - 5.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The equation of a line is y = mx + c
(3, 1) = (a, b)
(1, -3) = (c, d)
Slope:
= (d - b) / (c - a)
= (-3 - 1) / (1 - 3)
= -4 / -2
= 2
m = 2
Now,
We can choose any point and set it as (x, y) and substitute it in the equation.
(3, 1) = (x, y)
y = mx + c
1 = 2 x 3 + c
1 = 6 + c
c = 1 - 6
c = -5
Now,
m = 2
c = -5
The equation of the line that passes through the point (3, 1) and (1, -3) is
y = 2x - 5.

What is the image of the point (0,1) after a rotation of 270^ ∘ counterclockwise about the origin?
Answer:
it should be 1,1. nnhbnhh vfc thg there eventual
The image of the point (0,1) after a rotation of 270^ ∘ counterclockwise about the origin is (-1, 0).
How does rotation by 90 degrees changes the coordinates of a point if rotation is concerning origin?Let the point be having coordinates (x,y).
Case 1: If the point is in the first quadrant:
Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
Case 2: If the point is in the second quadrant:
Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
Case 3: If the point is in the third quadrant:
Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
For points on axes, it can take that point in any of the two surrounding quadrants. Since if the point is on the positive x-axis, then it can take as of the first quadrant or fourth quadrant.
There is no effect as we assumed rotation is concerning origin.
(0,1) ---- (-1, 0)
Hence, the image of the point (0,1) after a rotation of 270^ ∘ counterclockwise about the origin is (-1, 0).
