Answers

Answer 1

Answer:

75(b - 4) = 450

Step-by-step explanation:

Brainly already had a question like this lol

Answer 2
(B - 6) Because 75 x 6 equals to 450 but since you can get 4 free it will be (B - 6)

For this shape there are four points. The plotted ordered pairs are:
M = (3, 9)
N = (6, 0)
O = (3, 6)
P = (-3, 0)

All you have to do is multiply the BOTH x- and y-values by 1/3 on EACH ordered pair. And if it’s easier, you can divide by 3 as well. It’s the same thing.

M = (3, 9) = (3*1/3, 9*1/3) = (1, 3)
N = (6, 0) = (6*1/3, 0*1/3) = (2, 0)
O = (3, 6) = (3*1/3, 6*1/3) = (1, 2)
P = (-3, 0) = (-3*1/3, 0*1/3) = (-1, 0)

(1, 3) , (2, 0) , (1, 2) , and (-1, 0) are your points.

Answers

Answer:

57.74‬ yd²

Step-by-step explanation:

First, find the area of the "rectangle" as if there weren't different figure cut out of it:

(5+6+5)8

16(8)

128 yd²

Next, we are going to find the area of the four figures that are cut out from the rectangle. The circle at the bottom, the rectangle at the top, and the triangles on each side.

The first shape we can tackle will be the circle. The formula for finding the area of a circle is πr² or in this case 3.14r². The diameter of the circle is 6 yards, and half of the diameter is equal to the radius which gives us 3 yards as the length. Now simplify the expression:

3.14(3)²

3.14(9)

28.26 yd² is the area of the circle.

Next, we're going to find the area of the rectangle at the top. It's dimensions are 6 yards by 3 yards, which gives us an easy 18 yards² as the area (lxw).

Now we're going to solve for the area of the triangles. By the looks of the general dimensions of this shape, I am assuming these triangles are  congruent to each other, which means we will only have to solve for its area once. To find the area of a triangle we have to use the expression: (lxw)/2. However, we don't know one of those dimensions. We know that the length is 8 yards as shown in the diagram, and by using the widths 2 yards and 5 yards, and their relation to the triangle, we can deduce the width is 3 yards. Now we have values necessary to simplify the expression:

(8x3)/2

24/2

12 yards² is the area of one triangle.

Because I stated previously that the triangles are congruent, they both have an area of 12 yards. Now we add the areas of each of the four figures, and subtract them from the area of our large rectangle:

128-(12+12+28.26+18)

128-70.26

57.74‬ yd² is the area of the shaded region

Question 5 options:

1/4 =0.25=20%

1/4 =0.20=25%

1/2 =0.25=25%

1/4 =0.25=25%

Answers

Answer:

1/4=0.25=25%

Step-by-step explanation:

A coin has two sides, heads and tails, and if you take 100% divided by two you get 50, you want to know what is the probability it will land on tails TWICE so divide 50 by two and you get 25.

1/2=50

1/4=25

0.25 x 100= 25%

A waitress earned $9 per hour at her job plus an additional $75 in tips on Friday. She earned more than $150 total. Which inequality best represents the situation, where h represents the number of hours she worked on Friday? *

A. 9 + 75h > 150
B. 9 + 75h ≥ 150
C. 9h + 75 > 150
D. 9h + 75 ≥ 150

Answers

Answer:

the answer is c :)

Step-by-step explanation:

Answer:

C. 9h + 75 > 150

Step-by-step explanation:

One part is that it says that she makes more than, not more than or equal too 150. Which cuts the options down to two.

A. and C.

The second thing that the text says is that she makes 9 dollars and hour, not 75 an hour. Which means that A. can't be the answer.

Thus, C. is the correct answer.

Trish is ordering t-shirts from a website that charges a certain amount per t-shirt plus a flat rate for shipping. The cost for a given number of t-shirts is shown in the table.

20a. Write an equation to represent the situation. (Write your answer with no spaces, all lowercase letters, and write the slope as a decimal)

20b. What does the slope mean in the context of the situation?

20c. What does the y-intercept mean in the context of the situation?

Answers

Answer:

Hope this helps

Step-by-step explanation:

T means amount of t shirts they are buying

5.99 is amount of shipping cost

first do 32.24-5.99=26.25

then do 26.25/3=8.75

so 8.75= cost of shirt

20a.  (8.75*T)+5.99

20b.(I might get this part wrong just let me know)

M=Y2-Y1/X2-X1

so  32.24-5.99/3-0= 26.25/3 Or 8.75

20c=Y=Mx+B

3=8.75(32.24)+b=-279.1

Step-by-step explanation:

Number of red marbles=4

Number of blue marbles=3

P(B)=3/10

P(R)=4/10=2/5

Total number of marbles=10

Answer:

The number of red marbles is 4. The number of blue marbles is 3. The total number of marbles is 10 because 4+3+3 is 10. P(red) is 2/5 because there are 10 total marbles and there are 4 marbles which is equal to 4/10 marbles are red, and you simplify 4/10 to 2/5. P(blue) is 3/10 because there are 3 blue marbles out of 10 marbles.

Write the equation of the line in slope-intercept form using y=mx+b​

Answers

Answer:

y=-2x+2

Step-by-step explanation:

Answer:

y = -2x +2

Step-by-step explanation:

y = mx + b

m = slope

y2 - y1/x2 - x1 = m

Using two points, plug in the x values and y values into the equation to find slope.

(0, 2) (1, 0)

2 - 0/0 - 1 = 2/-1 = -2

m = -2

y = -2x + b

b = y-intercept

The y-intercept is the number that crosses through the y axis with an x value of 0.

(0, 2)

b = 2

y = -2x + 2
