Answer:

B.) About 2 hours

Step-by-step explanation:

Well the Full volume of the tank is 1440 cubic feet. If you multiply 15 by sixty, thats 900. 900 is cubic feet per hour, so there are 1.6 times 900 in 1440. Therefore 1.6 hours to drain the whole thing and B is the closest answer.

John bought a used truck for $4,500. He made an agreement with the dealer to put $1,500 down and make payments of $350 for the n

butalik [34]

The price of the truck is 4500 dollars.
But he paid it into breakdown:
=> 1500 dollars first payment
=> 350 dollars = 10 months => 350 * 10 = 3500 dollars
=> Total = 3500 + 1500 = 5000 dollars
=> 5000 - 4500 = 500 dollars additional for 10 months
=> 500 / 10 = 50 dollars per month
=> 50 * 12 = 600 dollars for 1 year
=> 600 / 4500 = 13.33% of the yearly interest.

Answer:

In 4 years, you will have $2,635.38

Step-by-step explanation:

The formula for annual compound interest, including principal sum, is:

A = P (1 + r/n) ^ (nt)

Where:

A = the future value of the investment/loan, including interest

P = the principal investment amount (the initial deposit or loan amount)

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per year

t = the number of years the money is invested or borrowed for

Note that this formula gives you the future value of an investment or loan, which is compound interest plus the principal. Should you wish to calculate the compound interest only, you need this:

Total compounded interest = P (1 + r/n) ^ (nt) - P

This is so confusing all of it makes no sense

Answer:

D). $4\sqrt{2}$

Step-by-step explanation:

STEP 1a: Find the last angle of the triangle. ( which is angle A)

$A+90+45=180$

STEP 1b: Solve the equation for A by adding 90 and 45.

$A+135=180$

STEP 1c: Then Move all terms not containing A to the right side of the equation by subtracting 135 from both sides of the equation

$A=180-135$

STEP 1d: Subtract 135 from 180.

$A=45$

STEP 2a: Find side b next.

STEP 2b: The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.

$cos(A)=\frac{adj}{hyp}$

STEP 2c: Substitute the name of each side into the definition of the cosine function.

$cos(A)=\frac{b}{c}$

STEP 2d: Set up the equation to solve for the adjacent side, in this case b.

$b=c*cos(A)$

STEP 2e: Substitute the values of each variable into the formula for cosine.

$b=8*cos(45)$

STEP 2f: Cancel the common factor of 2.

$a=4\sqrt{2}$

You are remodeling your kitchen. You've contacted two tiling companies who gladly told you how long it took their workers to til

quester [9]

Ok so pete lays 10 more than jim per hour

pete and jim laid same amount of tiles

j=jim's rate
p=pete's rate

6j=5p

but pete lays 10 tile per hour faster so
p=10+j

sub
6j=5(10+j)
6j=50+5j
minus 5j both sides
j=50

jim can lay at 50 tiles per hour
