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.
Answer:
the answer is kind of 10.41 but the real answer is 10 5/12 (khan academy)

5.) b
3x - 24 = 81 (add 24 on both sides)
3x = 105 (divide by 3 on both sides)
x = 35 or 105/3
6.) a
-5x - 25 = 78 (1st add 25 on both sides)
-5x = 103 (2nd divide both sides by -5)
x = -20.6

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?
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

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.

Answer:
5(x+3)
Step-by-step explanation:
Find the Greatest Common Factor (GCF).
GCF = 55
2 Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
5(\frac{5x}{5}+\frac{15}{5})5(

Find the x and y Intercepts
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
