Usain Bolt of Jamaica set a world record in 2009 for the 200- meter dash with a time of 19.19 seconds. What was his average speed
Answer:
His average speed was of 10.42 m/s
Step-by-step explanation:
We use the following relation to solve this question:
[tex]v = \frac{d}{t}[/tex]
In which v is the velocity(in m/s), d is the distance(in meters), and t is the time, in seconds.
Usain Bolt of Jamaica set a world record in 2009 for the 200- meter dash with a time of 19.19 seconds.
This means that [tex]d = 200, t = 19.19[/tex]
So his average speed was of:
[tex]v = \frac{d}{t} = \frac{200}{19.19} = 10.42[/tex]
His average speed was of 10.42 m/s

-1/4 (2x + 8) = -6
Multiply both sides by -4.
2x + 8 = 24
Subtract 8 from both sides.
2x = 16
Divide both sides by 2.

A. 7/32
b 1
c 3
d 3 1/2
Answer: C
Step-by-step explanation:
Answer and Step-by-step explanation:
The answer is C.
[tex]\frac{1}{4} = \frac{2}{8}\\\\[/tex]
Each friend will be receiving [tex]\frac{2}{8}[/tex] of a pizza.
[tex]\frac{7}{8} - \frac{2}{8} - \frac{2}{8} - \frac{2}{8} = \frac{1}{8}[/tex]
You can't give someone [tex]\frac{1}{8}[/tex] of a pizza, and you can't have half of a friend, so that one remains uneaten. This means that you give pizza to 3 friends.

Find the simple interest rate of a loan of $5,000 that is made for three years and requires $1,762.50 in interes
Answer:
11.75%
Step-by-step explanation:
The formula for Simple Interest is given as:
I = PRT
Where in the question
I = Interest = $,1762.5
P = Principal = $5,000
T = Time= 3 years
R = Simple Interest rate ??
To solve for R, the formula is given as:
R = I/PT
R = $1,762.5/5,000 × 3
R = 0.1175
Converting to percentage
= 0.1175 × 100
= 11.75%

The diagram shows a square.
(7x + 3) cm
Find the length of the side of the square.
3cm
(5x + 8) cm
Answer:
Step-by-step explanation:
The four sides of a square are equal.
7x + 3 = 5x + 8 Subtract 5x from both sides
7x - 5x + 3 = 8 Combine the left
2x + 3 = 8 Subtract 3 from both sides
2x = 8-3 Combine the right
2x = 5 Divide by 2
x = 5/2
x = 2.5
That is not quite the answer
Side = 7x + 3
Side = 7*2.5 + 3
Side = 17.5 + 3
Side = 20.5
