Mike had a coupon for 20% off the price of a shirt at a certain store. What was the amount of the additional discount Mike received? • On the day he went, the store was also having a sale. • The original price of the shirt was $25.50. • The price after the coupon and the additional discount was $18.36. (A) 7% B) 10% © 27% D 30%​

Answer:

80°

Step-by-step explanation:

20°+80°+missing angle=180°

missing angle=180°-100°=80°

Answer:

B. 81 m²

Step-by-step explanation:

6x10 = 60

7x6 = 42

42/2 = 21

60+21 = 81

Answer:

B) 81 meters squared

Step-by-step explanation:

rectangle = 6 * 10 = 60

triangle = .5 * 6 * 7 = 21

60+21 = 81

Answer:

84

Explanation:

400 × 21%

= 400 ÷ 100 x 21 (because 21% = 21/100)

= 84

Answer:

L's coordinates would go from being (x,y) to (-x, -y)

Step-by-step explanation:

So like, if L's coordinates were (5, 7) after rotation it would be (-5, -7)

If you were working backward and with L' being rotated you would do (-5, -7) change the sign and do (5,7) for L

Consenquently if you had a negative to begin with- L (-3, -4) L' would be the opposite sign and be (3,4)

Answer: The side of the house will the ladder reached by ladder = 16.52 feet

Step-by-step explanation:

House is standing vertical on the ground.

By placing ladder, it will become a right triangle with hypotenuse as ladder.

By Pythagoras theorem,

[tex](hypotenuse)^2=(perpendicular)^2+(base)^2[/tex]

i.e.

[tex](17)^2=(Height \ of\ wall\ reached\ by\ ladder)^2+4^2\\\\\Rightarrow\ (Height \ of\ wall\ reached\ by\ ladder)^2=289-16\\\\\Rightarrow\ (Height \ of\ wall\ reached\ by\ ladder)^2=273\\\\\Rightarrow\ (Height \ of\ wall\ reached\ by\ ladder)=\sqrt{273}\approx16.52[/tex]

Hence, the side of the house will the ladder reached by ladder = 16.52 feet (approx)

Answer:

Step-by-step explanation:

2x + y = 5       ← given line

2x + y = C      ← any parallel line

The line passing through (0, 1), therefore:

2×0 + 1 = C

C = 1

2x + y = 1    ←  the parallel line that passes through (0, 1)

To change it to slope-intercept form we just need to subtract 2x from both sides:

y = -2x + 1

Answer:

y = -1/5x + 6

Step-by-step explanation:

First rearrange x + 5y = 10 into y = mx + b format.

x + 5y = 10

5y = -x +10

y = -1/5x + 2

If a line is parallel to y = -1/5x + 2, it must have the same slope (-1/5).

Plug in for y = mx + b

x (x coordinate) = -5

y (y coordinate) = 7

m (slope) = -1/5

Solve for b.

7 = -5(-1/5) + b

7 = 1 + b

b = 6

y = -1/5x + 6 is parallel.

Answer: 195

Step-by-step explanation:

585/9=65

65*3=195

Answer:

The answer is 195 students.

Step-by-step explanation:

There are 2 solutions for this.

1st solution.

1. Start with the basics, the number of pictures we have altogether, 585.

2. Divide the number 585 by the number of students which is 3 to identify the total number of students that reported the 585 pictures.

3. 585/3 = 195, the total number of students.

2nd solution.

1. Start with the total again, the number of pictures we have altogether, 585.

2. Divide the number 585 by the number of pictures in each group total received pictures which is 9.

3. 585 divided by 9 = 65.

4. Take the number 65 which is the number of groups and multiply it by 3 the number of students in each group which will lead to the answer 195 again.

5. 195 is the number of students in total.

6. Extra: to even re-check your answers, multiply 195 by 3 and u will get 585, because each student did 3 reports.

Answer:

I hope I didn't make mistakes, because I solved it without calculator

Step-by-step explanation:

[tex] \frac{5}{3} s + \frac{19}{15} = - \frac{3}{5} \\ \frac{5}{3} s = - \frac{3}{5} - \frac{19}{15} \\ \frac{5}{3} s = \frac{ - 9 - 19}{15} \\ \frac{5}{3} s = \frac{ - 28}{15} \\ s = - \frac{28}{15} \times \frac{3}{5} [/tex]

[tex]s = - \frac{28}{25} [/tex]

Answer:

EZ Excavation: y = 24.5x

Happy Hauling Service: y = 25x

Step-by-step explanation:

✔️Equation for EZ Excavation:

This can be written in slope-intercept form, y = kx

Where k is the unit rate/slope/constant of proportionality

y = cost

x = dirt

Thus,

k = y/x

Using any given pair of values from the table, say, (8, 196),

k = 196/8

k = 24.5

To write the equation, substitute k = 24.5 into y = kx

Thus:

y = 24.5x

✔️Equation for Happy Hauling Service:

This can be written in slope-intercept form, y = kx

Where k is the unit rate/slope/constant of proportionality

y = cost

x = dirt

Thus,

k = y/x

Using the coordinate of any point on the line, say (1, 25),

k = 25/1

k = 25

To write the equation, substitute k = 25 into y = kx

Thus:

y = 25x

Answer:

2 5/14

Step-by-step explanation:

Answer:

down here (no pair for 1/3 so i made one up)

Step-by-step explanation:

2/8 = 1/4

4/8 = 1/2

1/3 = 2/6

6/10 = 3/5

Answer:

Cheetah

Blue Wildebeest

Brown Hare

Elk

Step-by-step explanation:

Divide the distance by the time.

Blue Wildebeest: 33 1/3 divided by 2/3 = 50

Brown Hare: 8 divided by 1/6 = 48

Cheetah: 7 divided by 1/10 = 70

Elk: 18 divided by 2/5 = 45

Now you have to order the animals from who has the biggest number(top) to who has the smallest number (bottom).

Answer:

Elk

Brown Hare

Blue Wildebeast

Cheetah

Step-by-step explanation:

Divide the distance by time to make percent

Blue Wildebeast- 33 1/3 ÷ 2/3 = 50%

Brown Hare- 8 ÷ 1/6 = 48%

Cheetah- 7 ÷ 1/10 = 70%

Elk- 18 ÷ 2/5 = 45 %

Least to Greatest: 45%, 48%, 50%, 70%

Least (top) to Greatest (bottom): Elk, Brown Hare, Blue Wildebeast, Cheetah
