Answer:

x=26

Step-by-step explanation:

by definition of alternate exterior angle rule 8x -71 = 5x +7

What you want to do is get your X's on one side I recommend subtracting 5x so that you don't have to deal with negative values.

8x-5x-71=5x-5x+7

3x-71=7

add 71 to both sides the goal now is trying to get by itself

3x-71+71=7+71

3x=78

now divide both sides by 3

3x/3=78/3

x=26

Round 8.1074 to the nearest hundredth?

likoan [24]

Answer:

8.11

Step-by-step explanation:

You round it up because the 3rd number (thousandths) is 5 or above, and since it's 7 you round that up and drop off the last number.

These are the fees for sending a package by Media Mail:

Serga [27]

For first pound it is = $2.41
For next six, = 0.41 * 6 = $2.46

Remaining = 7.99 - (2.41 + 2.46) = 7.99 - 4.87 = 3.12

Now, additional pounds = 3.12 / 0.39 = 8
Total weight = 1 + 6 + 8 = 15

In short, Your Answer would be 15 pounds

Hope this helps!

Julie and her brother go to Atlanta to ride the SkyView Ferris wheel. It measures 200 feet in diameter.

LUCKY_DIMON [66]

Answer:

Part A) Circumference

Part B) C=π D

Part C) The distance traveled in one rotation is 628.32 feet

Step-by-step explanation:

Part A) we know that

The distance around the circle is equal to the circumference.

The Ferris Wheel have a circular shape

To find out the distance around the Ferris Wheel you should use the circumference

Part B) What is the formula needed to solve this problem?

we know that

The circumference is equal to multiply the number π by the diameter of the circle

C=π D

Part C) What is the distance traveled in one rotation?

we know that

One rotation subtends a central angle of 360 degrees

The distance traveled in one rotation is the same that the circumference of the Ferris wheel

we have

$D=200\ ft$ ----> diameter of the Ferris wheel

substitute in the formula of circumference

$C=\pi (200)\\C=200\pi\ ft$

assume

$\pi=3.1416\\C=200(3.1416)=628.32\ ft$

therefore

The distance traveled in one rotation is 628.32 feet

Multiply (-3x+4)(2x-1) that’s the question

ad-work [718]

The given expression is

(-3x+4)(2x-1)

To multiply, we would apply the distributive property of multiplication. We would multiply each term in the first parentheses with each term in the second. We have

(- 3x * 2x) + (- 3x * - 1) + (4 * 2x) + (4 * - 1)

= - 6x^2 + 3x + 8x - 4

= - 6x^2 + 11x - 4
