Step-by-step explanation:

Number of employees exceeded their sales quota = 17

Number of employees met their sales quota = 13

Number of employees didn't exceed their sales quota = 3

Now, we need to find the ratio of the number employees who exceeded their sales quota to the number of employees who didn't exceed their sales quota.

4(2a + 2) = 8(2 - 3a) whats A? please help me!!!!

Reptile [31]

Answer:

a = $\frac{3}{8}$

Step-by-step explanation:

4(2a + 2) = 8(2 - 3a)

Distribute.

8a + 4 = 16 - 24a

Add 24a to each side.

32a + 4 = 16

Subtract 4 from each side.

32a = 12

Divide 32 from each side.

a = $\frac{3}{8}$

A population of rabbits is described by the function R(t) = 100(2t/5), where t is measured in months and R is measured in rabbit

Savatey [412]

Answer and Step-by-step explanation: The graph is shown in the attachment.

a. ΔR on [1,2] is mathematically expressed as:

ΔR = R(2) - R(1)

which means difference of population of rabbits after 2 months and after 1 month.

$R(1) = 100(\frac{2}{5}.1 )$

$R(1) = 100(\frac{2}{5} )$

R(2) = $100(\frac{2}{5}.2 )$

$R(2) = 100(\frac{4}{5} )$

$\Delta R = 100(\frac{4}{5} )-100(\frac{2}{5} )$

$\Delta R = 100[\frac{4}{5} - \frac{2}{5} ]$

$\Delta R=$ 40

Difference of rabbits between first and second months is 40.

b. R(0) = 100( $\frac{2}{5} .0$ )

R(0) = 0

Initially, there no rabbits in the population.

c. R(10) = $100(\frac{2}{5}.10 )$

R(10) = 400

In 10 months, there will be 400 rabbits.

d. R(t) = 500

$500=100(\frac{2}{5}.t )$

$\frac{500}{100}=\frac{2}{5}.t$

$t = \frac{500.5}{100.2}$

t = 12.5

In 12 and half months, population of rabbits will be 500.

Joshua uses the Small Business Administration (SBA) Loan Program to obtain a loan to help expand his vending machine business. J

TiliK225 [7]

Answer:

Step-by-step explanation:

Alright, lets get started.

Principal amount Joshua borrowed, P = $ 25000

rate of interest, r = 1.5 %

time, t = 2 years

simple interest = $\frac{P*r*t}{100}$

simple interest = $\frac{25000*1.5*2}{100}=750$

Means $ 750 will be the interest of Joshua's loan.

So, Joshua needs to repay the SBA = $25000+750=25750$

Hence, Joshua will repay $ 25750 to SBA after two years. : Answer

Hope it will help :)
