Speed is distance over time. There’s no distance in the question and the time is 1 hr 30 mins hence 1.5 hours.

13. If the following fractions were converted to decimals, which one would result in a repeating decimal? A. 3/4 B. 1/9 C. 5/11

Vladimir [108]

Hey there!

In order to find if a fraction would result in a repeating decimal, recall that a fraction is a division problem written vertically. All that you have to do is divide the numerator by the denominator. Also, remember that a repeating decimal will result in the same number after the decimal point as long as the calculator can handle.

3 ÷ 4 = 0.75

1 ÷ 9 = 0.11111111...

5 ÷ 11 = 0.45454545...

3 ÷ 0.42857143...

As you can see, two out of your four answer choices give you a repeating decimal. B gives you a repeated number of "1" while C gives you "45". D doesn't count since there is no pattern of repeated numbers that it follows.

Both B and C fall into the category of repeating decimal. If you're only able to choose one answer, I would ask your teacher, a parent, or a peer what they think.

Hope this helped you out! :-)

The length of a rectangle is 5 more than 3 times the width. Write and solve an equation to find the width (w) if the length is 1

GenaCL600 [577]

Answer:

Length = 42.5 cm

Step-by-step explanation:

length of rectangle = 5 + 3w

So l = 5 + 3w where w = 12.5

Equation:

L = 5 + 3(12.5)

Solving the Equation:

L = 5 + 3(12.5)

L = 5 + 36 + 1.5

L = 42.5

Length: 42.5 cm

Amelia has 3 gallons of paint .Mason have 10 quarts .How many more pints of paint does AMELIA have then mason.

Ber [7]

Answer:

4 Pints

Step-by-step explanation:

According to the scenario, calculations are as follows,

As we know, 1 gallon = 8 Pints

1 Quarts = 2 Pints

So, Amelia = 3 Gallons = 3 × 8 Pints = 24 Pints

Mason = 10 quarts = 10 × 2 Pints = 20 Pints

So, Number of more pints Amelia has = Amelia number of pints - Mason number of pints

= 24 pints - 20 pints

= 4 Pints

According to a National Health Survey, American men’s heights are normally distributed with a mean given by μ=69.7 inches and a

Novay_Z [31]

Answer: 0.206

Step-by-step explanation:

Given that :

Height of American men is normally distributed :

Mean height (μ) = 69.7 inch

Standard deviation (σ) = 2.8 inch

Probability that height of a randomly selected man is more than 72 inches

P(X > 72)

Obtain the standardized score (Zscore):

Zscore = (x - μ) / σ

Zscore = (72 - 69.7) / 2.8

Zscore = 2.3 / 2.8

Zscore = 0.8214285

Zscore = 0.8214

Using the Z probability calculator ;

P(Z > 0.8214) = 0.20571

Probability of selecting a man whose height is more Than 72 is 0.206

mrs. fuentes earns a salary of 60,000. ms. williams earns a salary of 51,000. mrs fuentes will receive a salary increase of 1,52

BlackZzzverrR [31]

Answer:

( $2,525 - $1,525)x = $9,000

Step-by-step explanation:

Data provided:

Salary earned by Mrs. Fuentes = $60,000

Salary earned by Ms. Williams = $51,000

Increase in salary of Mrs Fuentes = $1,525 per year

Increase in salary of Ms Williams = $2,525 per year

since, x is the number of years after which their salary will be equal

Now,

Total salary of Mrs. Fuentes after x years = $60,000 + $1,525x

and,

Total salary of Ms. Williams after x years = $51,000 + $2,525x

also,

when their salaries are equal

$60,000 + $1,525x = $51,000 + $2,525x

$2,525x - $1,525x = $60,000 - $51,000

( $2,525 - $1,525)x = $9,000
