Answer: Hi!

The equation given is 6.6 * 10^5.

First, we will solve the exponent.

10^5 = 100,000

Next, we will multiply 100,000 by 6.6.

100,000 * 6.6 = 660,000

Therefore, your answer is b), 660,000.

Hope this helps!

The perimeter of a rectangle is 80 inches, if the width is 18 inches what is the area of the rectangle? A.22 sq.in B.324 sq.in C

Tanya [424]

Answer:

396 in^2

Step-by-step explanation:

The perimeter of a triangle is given by the formula:

● P = 2w+2L

L is the length and w is the width

■■■■■■■■■■■■■■■■■■■■■■■■■■

The width hereis 18 inches and the perimeter is 80 inches.

Replace w by 18 and P by 80 to find L.

● P= 2L+2w

● 80 = 2L + 2×18

● 80 = 2L + 36

Substrat 36 from both sides

● 80-36 = 2L+36-36

●44 = 2L

Divide both sides by 2

● 44/2 = 2L/2

● 22 = L

So the length is 22 inches

■■■■■■■■■■■■■■■■■■■■■■■■■■

The area of a rectangle is given by the formula:

● A= L×w

● A = 22×18

● A = 396 in^2

Cal's go cart has a gas tank with the dimensions shown below. He uses a gas can that holds 11 gallon of gas, to fill the go cart

RSB [31]

Answer:

This question is incomplete as no image was attached. Please find the missing image in the attachment. Also, this is the correct question:

Cal's go cart has a gas tank with the dimensions shown below. He uses a gas can that holds 1 gallon of gas, to fill the go cart tank. 1 gallon = 231 inches^3. How many full gas cans will it take to fill the go cart's gas tank?

Answer: 2 full gas cans

Step-by-step explanation:

From the image, we have the following dimensions:

length, l = 15.4 inches (in)

width, w = 10 in

height, h = 3 in.

The volume of the gas tank (which is rectangular) is given as:

$Volume = length * width * height = lwh\\\\Volume = 15.4 * 10 * 3 = 462 cubic inches = 462in^{3}$

NB: The unit of volume is cubic units. In this example, it is cubic inches.

The gas can being used to fill the tank holds 1 gallon of gas = $231in^{3}$

The total volume to be filled is $462in^{3}$ of gas.

So, it will take $\frac{462in^{3} }{231in^{3} } = 2$ full gas cans to fill the go cart's gas tank.

Therefore, the answer is 2.

-1/4d-2/5d=39 <br> Solve for d <br> Please explain I don’t understand

Papessa [141]

Given:

The equation is

$-\dfrac{1}{4}d-\dfrac{2}{5}d=39$

To find:

The value of d.

Solution:

We have,

$-\dfrac{1}{4}d-\dfrac{2}{5}d=39$

Taking LCM, we get

$\dfrac{-5d-8d}{20}=39$

$\dfrac{-13d}{20}=39$

Multiply both sides by 20.

$-13d=39\times 20$

Divide both sides by -13.

$d=\dfrac{39\times 20}{-13}$

$d=-3\times 20$

$d=-60$

Therefore, the value of d is -60.
