A washer and a dryer cost $834 combined. The washer costs $84 more than the dryer. What is the cost of the dryer? ​

Answers

Answer 1
W + D = 834
W = D + 84
Use substitution
D + 84 + D = 834
2D = 750, D = 375
The cost of the dryer is $375
Answer 2

Answer:

The dryer cost $375

Step-by-step explanation:

834/2 = 417

84/2 = 42

417 - 42 = 375

834 - 375 = 459

459 - 84 = 375

PROOF: 417 - 375 = 42 then double that answer to get 84

Maria deposited $5,700 in an account that earns 8% simple interest. Maria made no withdrawals or deposits. What will be the total amount of money in her account after 6 years?

Answers

Answer:

The total amount of money in Maria's account after 6 years is $8436

Step-by-step explanation:

Given;

principal amount , P = $5,700

interest rate, r = 8 % = 0.08

time of investment, t = 6 years

The interest on the invested money after 6 years is given by;

I = Prt

I = $5,700 x 0.08 x 6

I = $2736

Total amount in Maria's account is given by;

A = P + I

A = $5,700 + $2736

A = $8436

Therefore, the total amount of money in Maria's account after 6 years is $8436

Explanation:

So if we use the formula a^2+b^2=c^2

We would fill it in as 4^2+b^2=18^2
Then solve

16+b^2= 324

Then subtract 16 from both sides

B^2 = 308

Molly invested $50,000 in various stocks and bonds. She earned 15% on the bonds and 18% on the stocks. Molly's total profit on both types of investments was $8700, how much of the $50,000 did she invest in bonds?

Answers

Answer:

$10000

Step-by-step explanation:

Given that:

Molly invested $50,000 in various stocks and bonds.

She earned 15% on bonds and 18% on stocks

Let the bonds be denoted by a

However, her profit on both types of investment is said to be $8700

We are to find how much of the $50,000 did she invest in bonds.

i.e

0.15a + 0.18(50000-a)  = 8700

open brackets

0.15a + 9000 - 0.18a = 8700

Collect like terms

0.15a - 0.18a = 8700 - 9000

-0.03a  = -300

Divide both sides by(-0.03); we get

a = 10000

Thus, Molly invested $10000 in the bonds.

Erika and Bradley want to hike the Big Cypress Trail. They will hike a total of 72 milles FErika and Bradley want to hike 16 miles each day, how many days will they hike exadty 16 miles? They will hike exactly 16 miles each day for days.

Answers

Answer: They will hike exactly 16 miles each day for 4 days.

Step-by-step explanation:

Given: Total distance to hike = 72 miles

They hike 16 miles per day.

Total days they will take to complete the distance = [tex]\dfrac{\text{Total distance to hike}}{\text{Distance hiked each day}}[/tex]

[tex]=\dfrac{72}{16}\\\\=\dfrac{9\times8}{2\times8}=\dfrac92\\\\=4\dfrac12[/tex]

It will take 4 complete days and a half day to complete the journey.

i.e. They will hike exactly 16 miles each day for 4 days.

given f(x) and g(x) = f(x + k) use the graph to determine the value of k

Answers

answer:
g(x) = f(x+6)
x = 6

step-by-step explanation:
given:
g(x) = f(x+k)

if value of k > 1 then the graph shifts k units to the left.
if value of k < 1 then the graph shifts k units to the right.

from the graph, it is clear that the function g(x) has moved 6 units (-4 to -10) to the left of f(x). this shows that the value of k > 1 and it is = 6 units

thus the transformation rule can be given as:
g(x) = f(x+6)
k = 6
