What times what equals 42?

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

Answer:

[tex]2\sqrt{2}[/tex]

Step-by-step explanation:

h(10) = 2(10) - 8

        = 12

g(h(10)) = [tex]\sqrt{(12)-4}[/tex]

            = [tex]\sqrt{8}[/tex]

            = [tex]2\sqrt{2}[/tex]

Answer:

C. 2 hours

Step-by-step explanation:

50h= 190-45h

50h + 45h = 190

Answer:

(6 + 5) / r

Step-by-step explanation:

5 more means you're adding something to another number, in this case six. Throw them in brackets to abide by BEDMAS rules and divide it by r!

The expression for the given statement is 5+6/r

An expression in maths is a sentence with a minimum of two numbers or variables and at least one maths operation. This maths operation can be addition, subtraction, multiplication, or division.

Given is a statement Five more than six divided by a number r

The sentence says, 'Five more than six divided by a number r' we can also write the sentence as 'Five more than+6/r'. this mean that we need to add 5 to 6/r.

Hence, The expression for the given statement is 5+6/r

x = 8

Step-by-step explanation:

-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.

x = 8

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%

[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.

(6^2 + 10) / (-5 x 3) - 5

?

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
