Answer:

-11

Step-by-step explanation:

logb ( a^5 c^2 / d^6)

Splitting these into log (xy/z) = log x + log y - logz

logb ( a^5) +logb ( c^2) - logb( d^6)

We also know that log x^y = y log x

5logb ( a) +2logb ( c) - 6 logb( d)

Given logb ( a)=3 logb ( c) =2 logb( d)=5

5 * 3 + 2* 2 - 6* 5

15 +4 -30

19 - 30

-11

Jill, an employee at Old Navy, budgets 18 of her yearly salary for clothing. Jill's total clothing bill for the year is $8,180.

Triss [41]

Answer: $ 45,444.44

Step-by-step explanation:

Given: Jill budgets 18% of her yearly salary for clothing.

His total clothing bill for the year is $8,180.

Let x= her yearly salary

Then according to the question , we have

18% of x = 8180

Convert 18% into decimal by dividing it by 100 , we get

0.18 x= 8180

Multiply both sides by 100

⇒ 18x = 818000

Divide both sides by 18 , we get

x= 45444.44

Hence, her yearly salary = $ 45,444.44

Jenna knits scarves and then sells them on Etsy, an online marketplace. Let C(x) = 4x + 20 represent the cost C in

Alex Ar [27]

Answer:

Step-by-step explanation:

We are given that Jenna knits scarves and sells them on Etsy an online market place.

$C(x)=4x+20$

Where C=Represents the cost in dollars

x=Number of scarves

We have to create a table to show the relationship between the number of scarves x and the cost C

Substitute x=1

$C(1)=4(1)+20=$ $24

Substitute x=2

$C(2)=4(2)+20=$ $28

$C(3)=4(3)+20=$ $32

$C(4)=4(4)+20=$ $36

$C(5)=4(5)+20=$ $40

$C(6)=4(6)+20=$ $44
