Answer 1

Answer:

Average speed = 10.41 m/s

Step-by-step explanation:

It is given that, in 2009, Usain Bolt set the world record for sprinting 100 m on 9 3/5 seconds.

It can be assumed to find her average speed. Speed is equal to total distance covered divided by total time taken.

[tex]v=\dfrac{d}{t}\\\\v=\dfrac{100\ m}{9\dfrac{3}{5}\ s}\\\\=\dfrac{100}{\dfrac{48}{5}}\ m/s\\\\=\dfrac{500}{48}\ m/s\\\\=10.41\ m/s[/tex]

So, the average speed of Usain Bolt is 10.41 m/s.

8r + 206 + 7r +79 = 360

15r = 75

7(5) + 79

angle YMB is 114°

Answer: 30 degrees

Step-by-step explanation:

Since the are supplementary have them equal to 180 (degrees).

(8r + 206) + (7t + 79)= 18

Combine like terms

15r + 295= 180

Subtract 295 from both sides.

15r + 295-295= 180-295

15r = -105

Divide both sides by 15

15r/15= -105/15

r=-7

Solve for the measure of YMB.

Plug in -7 for r.

7(-7) + 79

-49 + 79

30 = YMB

2x - 3y = 6
Find the x and y Intercepts

Answers

Answer:

x-intercept(s): (3,0)

y-intercept(s): (0,−2)

Step-by-step explanation:

Answer:

x=3 and y=-2

Step-by-step explanation:

2x - 3y = 6

cancel out the y

2x - 3(0) = 6

2x = 6

divide both sides by 2

x = 3

2x - 3y = 6

cancel out the x

2(0) - 3y = 6

-3y = 6

divide both sides by -3

y = -2

After an earthquake, $$ 3 7​ of all claims were paid within a month. Of the remaining claims that had not yet been paid, $$ 2 5​ of them were paid within the second month. What fraction of all claims were paid in the second month?

Answers

Answer:

6/35

Step-by-step explanation:

After an earthquake, $$ 3 /7​ of all claims were paid within a month.

Let the total number of claims be represented by 1

Therefore, the amount of claims that were not paid within the month is calculated as:

1 - 3/7 = 4/7

Hence, 4/7 claims were not yet paid.

Of the remaining claims that had not yet been paid, $$ 2/5​ of them were paid within the second month. What fraction of all claims were paid in the second month?

This is calculated as:

2/5 of the claims that were not yet paid

= 2/5 of 4/7

= 2/5 × 4/7

= 6/35
