What is the simplified form of the following expression?

Answers

Answer 1

Answer:

Part a) $((4)/(7) )^(3)$

$((4)/(7) )^(3) =(4^(3))/(7^(3))= (64)/(343)$

therefore

the answer part a) is equal to

$(64)/(343)$

Part b) $(6xyz)/(2xz)$

$(6xyz)/(2xz)= ((2xz)(3y))/(2xz) = 3y$

therefore

the answer Part b) is equal to

$3y$

Answer 2

Answer: (4/7)^3=.1865

6xyz/2xz simplifies to 3y

Stephen has been saving money to buy a new car. The new car costs $21,920.00. He has to pay 17.25% in taxes based off the cost of the car. If he also purchases an extended warranty for $1,200.00, what is a reasonable estimate for the total price of the car?sorry the numbers were mixed up!

Answers

The total price of the car is $26901.20

Step-by-step explanation:

It is given that,

The cost of the new car = $21,920.00
The tax percent for the cost of the car = 17.25%
He also purchases an extended warranty for the car = $1,200.00

To find the total price of the car :

Total Price = cost of the car + Tax cost + warranty cost.

The cost of the car and warranty cost are already given. So, we need to calculate the Tax amount paid for the car.

Tax amount = 17.25% of $21,920.00

⇒ 17.25/100 × 21,920.00

⇒ 0.1725 × 21,920

⇒ 3781.2 dollars.

Therefore, the cost of tax is $3781.2

Now, coming to the total price of the car,

Total Price ⇒ 21,920.00 + 3781.20 + 1200.00 = 26901.20 dollars.

The total price of the car is $26901.20

Find the slope between (2,10) and (9,1).

Answers

The slope between (2,10) and (9,1) is -9/7.

We have given that,

(x1,y1)=(2,10) and(x2,y2)= (9,1).

What is the formula of the slope?

Slope=rise/run

Sope=y2-y1/x2-x1

use the given values in above formula so we get,

1-10/9-2=-9/7

So, the slope is -9/7.
