Krissa exercises daily by walking. She aims to walk at a steady rate of 3.4 miles per hour.


a. If t represents time in hours and d represents distance in miles, write an equation that models the relationship between these variables.



b. Use your equation to calculate the distance Krissa will jog in 5/8 of an hour (round to the hundredths).



c. Use your equation to calculate how long it will take for Krissa to walk 5.44 miles.

Answers

Answer:

a. 3.4t (miles)

b. 2.125 miles

c. t = 1.6 hours

Step-by-step explanation:

A) We use this relation: Distance = time * speed ( speed or vitesse or rate)

So d= 3.4*t= 3.4t (miles)

B) If t= 5/8

then the distance d= 3.4* 5/8= 2.125 miles.

C) If the distance d= 5.44, we can find the time like:

d= 3.4*t, and we know d=5.44

so 5.44= 3.4*t or t = 5.44/3.4, t= 1.6 hours

How many distinct products can be formed using two different integers from the given set: {–6, –5, –4, –3, –2, –1, 0, 1, 2, 3, 4, 5}?

Answers

Number of distinct products that can be formed is 144

Permutation

Since we need to multiply two different integers to be selected from the set which contains a total of 12 integers. This is a permutation problem since we require distinct integers.

Now, for the first integer to be selected for the product, since we have 12 integers, it is to be arranged in 1 way. So, the permutation is ¹²P₁ = 12

For the second integer, we also have 12 integers to choose from to be arranged in 1 way. So, the permutation is ¹²P₁  = 12.

Number of distinct products

So, the number of distinct products that can be formed from these two integers are ¹²P₁ × ¹²P₁ = 12 × 12 = 144

So, the number of distinct products that can be formed is 144

(- 21, - 13 )

Step-by-step explanation:

- 3y + x = 18 → (1)

x = 2y + 5 → (2)

substitute x = 2y + 5 into (1)

- 3y + 2y + 5 = 18

- y + 5 = 18 ( subtract 5 from both sides )

- y = 13 ( multiply both sides by - 1 )

y = 13

substitute y = - 13 into (2)

x = 2(- 13) + 5 = - 26 + 5 = - 21

solution is (- 21, - 13 )

Mr. Smith earned $600 last year. His total deductions amounted to 10%
of his earnings. What was his take-home salary?

Answers

Answer:

540

Step-by-step explanation:

10% of 600 is 60, 600-60 is 540

The 10% of $600 will be $60 therefore, the net salary that Mr. Smith will take home will be $540.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Base salary = $600

10% of $600 = (10/100) x 600 = $60

Net salary = $600 - $60 = $540

Hence "The 10% of $600 will be $60 therefore, the net salary that Mr. Smith will take home will be $540.".
