Answer:

B. Kyle earned $4, each week for 3 weeks, for helping his brother maw the kwn. How much money did Kyle have at the end of 3 weeks ?

Step-by-step explanation:

Option B answers the question.

Analyzing B

$Earnings = \$4$ weekly

$Duration = 3\ weeks$

Total Earnings is calculated as thus:

$Total = Earnings * Duration$

$Total = \$4 * 3$

$Total = \$12$

Hence:

$\$4 * 3 = \$12$

Answer:

Step-by-step explanation:

Compound Interest

It's the type of financial calculations that includes the interest of previous periods into the new interests earned by some initial investment or principal P.

If we want to compute the final value FV of a series of n payments R at a fixed compound interest rate i, then

$FV=F_m\cdot R$

Where

$\displaystyle F_m=\frac{(1+i)^n-1}{i}$

The question provides us the following data

i=10% compounded twice a year

n=3 1/2 years

FV=15,000

We need to convert the number of periods and the interest rate to a semester base:

$\displaystyle i=\frac{10}{100\cdot 2}=0.05$

$n=3.5\cdot 2= 7\ semesters$

Let's calculate Fm

$\displaystyle F_m=\frac{(1+0.05)^7-1}{0.05}=8.142$

Knowing that

$FV=F_m\cdot R$

Solving for R

$\displaystyle R=\frac{FV}{F_m}=\frac{15,000}{8.142}=1,842.30$

Sara should deposit $1,842.30 twice a year to have the down payment for her own restaurant

Think of 5 positive integers that have a mode of 3, a median of 5, a mean of 7 and a range of 12.

kiruha [24]

For the mode to be 6, there has to be at least two 6s.

For the median to be 6, with two 6s, there must be at least one number above 6.

For the mean to be 6, the sum is 30, so the three remaining numbers must total 18.

Answer:

blue: $8.50
yellow: $6.50

Step-by-step explanation:

Each of the 2-gallon mixes is made of 8 "parts" of paint, so each "part" is 2/8 gallons = 1/4 gallon = 1 quart. We can let b and y represent the costs of 1 quart of blue and yellow paint, respectively.

Then the cost for 2 gallons is ...

3b + 5y = 58 . . . lime green

6b +2y = 64 . . . ocean blue

Subtracting the second equation from twice the first gives ...

2(3b +5y) -(6b +2y) = 2(58) -(64)

8y = 52

y = 6.5

From the first equation, ...

3b = 58 -5y = 58 -5·6.5 = 25.5

b = 25.5/3 = 8.5

The cost of 1 quart of blue paint is $8.50; the cost of 1 quart of yellow paint is $6.50.

A weather station on the top of a mountain reports that the temperature is currently 0°C and has been falling at a constant rate

____ [38]

Step-by-step explanation:

0 degrees now

so 3 degrees an hour means

3 degrees : 1 hour ago

3×3= 9

9 degrees : 3 hours ago

3×4.5 =13.5

13.5 degrees : 4.5 hours ago
