The students in Mr. Sanchez's class are converting distances measured in miles to kilometers. To estimate the number of kilometers, Abby takes the number of miles, doubles it, then subtracts 20% of the result. Renato first divides the number of miles by 5 and then multiplies the result by 8.

Write an algebraic expression for Abby's method.

Answer 1

Step-by-step explanation:

hay! these is my answer,,,,,, I hope these will help

Abby’s Expression:

Double m, giving 2m. She then takes 20% of the result, which we can write 0.2(2m). Finally she subtracts this from 2m, giving 2m−(0.2)2m

2m − (0.2)2m

Renato’s Expression:

Divide m by 5, giving m ÷ 5 = m/5, and then multiplies the result by 8, giving:

8(m/5)

so i’m not sure if there is a different way to do this but here’s how i did it:

start with 2:5

then just keep going up till you can add both numbers and get 28

so next i multiplied both sides by 2 to keep the ratio and got 4:10

then i went back and tried again and tried multiplying 3

which is 6:15.

that only is 21 students so it’s not right

next i tried 4

2 x 4 = 8

and

5 x 4 = 20

8:20 is still a 2:5 ratio and

8 + 20 = 28

so 8 students were in the teachers play

let me know if i can clarify anything
yes!! u r correct an no need for anything else i’m sure ur right and no need to clarify

Laila purchased a prepaid phone card for $25 . Long distance calls cost 24 cents a minute using this card. Laila used her card only once to make a long distance call. If the remaining credit on her card is $13.72 , how many minutes did her call last?

Answers

Answer:

The call lasted for 47 minutes.

Step-by-step explanation:

It is given that:

Value of prepaid card = $25

Cost per minute of long distance call = 24 cents = $0.24

Remaining credit = $13.72

Let,

x be the number of minutes

y be the remaining amount

y = 25 - 0.24x

13.72 = 25 - 0.24x

0.24x = 25 - 13.72

0.24x = 11.28

Dividing both sides by 0.24

[tex]\frac{0.24x}{0.24}=\frac{11.28}{0.24}\\x=47[/tex]

Therefore,

The call lasted for 47 minutes.

Answer:

circley-axis5 units

Step-by-step explanation:

It can be helpful to actually see the graph. For 0 ≤ θ ≤ π, a circle is developed above the x-axis, symmetrical about the y-axis (θ=π/2). For π ≤ θ ≤ 2π, the same circle is traced again in the same direction (CCW), as values of r are negative for those angles.

The circle has a radius of 2.5, centered at (0, 2.5), so the diameter is 5 units. The length of the diameter is the farthest distance between any two points on a circle.

5). x = 15

7). JL = 78

Step-by-step explanation:

We can solve these problems with the help of midsegment theorem.

Midsegment theorem:

"Segment joining midpoints of two sides of a triangle is parallel and half the measure of third side of the triangle"

Question 5

8x - 23 = [tex]\frac{1}{2}(10x+44)[/tex]

8x - 23 = 5x + 22

8x - 5x = 22 + 23

3x = 45

x = 15

Therefore, x = 15 is the answer.

Question 7

Since, MN is the midsegment,

MN = [tex]\frac{1}{2}(JL)[/tex]

5x - 16 = [tex]\frac{1}{2}(4x+34)[/tex]

5x - 16 = 2x + 17

5x - 2x = 17 + 16

3x = 33

x = 11

Therefore, Length of JL = 4(11) + 34

                                        = 44 + 34

                                        = 78 units
