question 8/10 please and thank you

Answers

Answer 1

Answer:

Step-by-step explanation:

These angles are alternate exterior angles and alternate exterior angles are equal when the lines are parallel

12x+8 = 13x+2

Subtract 12x from each side

12x+8-12x = 13x+2-12x

8 = x+2

subtract 2 from each side

8-2 =x

6 =x

Find the measure of the angle

12x+8

12*6+8

72+8

Water flows back and forth between a small and large tank. When water is moving into a tank the flow rate is

positive, and when water is moving from a tank the flow rate is negative. The large tank begins with 300 gallons of

water, and the small tank begins with 200 gallons of water. After a period of 5 minutes, the large tank has the same

amount of water as the small tank. Which statement describes the flow rate?

The flow rate of the large tank is 10 gal/min, and the flow rate of the small tank is -10 gal/min.

O The flow rate of the large tank is -10 gal/min, and the flow rate of the small tank is 10 gal/min.

The flow rate of the large tank is 20 gal/min, and the flow rate of the small tank is -20 gal/min.

The flow rate of the large tank is -20 gal/min, and the flow rate of the small tank is 20 gal/min.

Save and Exit

Answers

Answer:

D. The flow rate of the large tank is -20 gal/min, and the flow rate of the small tank is 20 gal/min.

Step-by-step explanation:

Flow rate = [tex]\frac{gallons of water}{minute}[/tex]

flow rate of water in the big tank = [tex]\frac{300}{5}[/tex]

= 60 gallons/minute

flow rate in the smaller tank = [tex]\frac{200}{5}[/tex]

= 40 gallons/minute

The difference in flow rate between the tanks = 60 - 40

= 20 gallons/minute

Since the two tanks have the same amount of water after the given time, then the volume of water in the large tank decrease; while the volume of water in the small tank increased.

Therefore, the flow rate of the large tank is -20 gal/min, and the flow rate of the small tank is 20 gal/min. This shows that option D is correct.

Jonathan bought a new car in November that cost $23,000. The value of the car decreases by 15% each year. What will the value of the car be in five years? *Give the exact value~nearest penny

Answers

Answer:

$5750

Step-by-step explanation:

To find what 15% is in money, we do

23,000*15/100=3450 for one year

3450*5(for five years)=$17,250

Now subtract that

23,000-17,250=$5750

2.) What is the perimeter of a polygon with vertices at (-3, 1), (5, 1), (-3, 4), (5, 4)?

Answers

Answer:

33.1 units

Step-by-step explanation:

The formula to find the sides of an shape when given vertices is

= √(x2 - x1)² + (y2 - y1)²

When we have:(x1, y1) and (x2, y2)

(-3, 1), (5, 1), (-3, 4), (5, 4)

For (-3, 1), (5, 1)

= √(5 - (-3))² + (1 -1)²

= √8² + 0²

= √64

= 8 units

For (5, 1), (-3, 4)

= √(-3 - 5)² + (4 - 1)²

= √-8² + 3²

= √64 + 9

= √73 units

For (-3, 4), (5, 4)

= √(5 - (-3))² + (4 - 4)²

= √8² + 0²

= √64

= 8 units

For (-3, 1), (5, 4)

= √(-3 - 5)² + (4- 1)²

= √8² + 3²

= √64 + 9

= √ 73 units

Perimeter of the Polygon:

=( 8 + √73 + 8 + √73) units

= 33.088007491 units

≈ 33.1 units

The third one from the top so 2nd to bottom

Answer:

Option A

Step-by-step explanation:

Rearrange and simplify them

First we simplify

5.78 , -5.9 , 58%(58/100) or 5.8 , -5.75

Now we rearrange

-5.9 , -5.75 , 5.78 , 5.8

The larger the number in negative is the smallest.

So option A is the answer

A report revealed that the average no. of months that an employee stays in a factory is 36 months. Assuming that
the no. of months of an employee tenure in the factory is normally distributed with a standard deviation of 6
months, find the probability that a certain employee will stay:
a. More than 30 months
b. Less than 24 months
c. Between 24 to 48 months

Answers

Answer:

a) P [X ≥ 30 ] = 0,8413 or 84,13%

b) P [X < 24] = 0,0228 or 2,28 %

c) P [ 24 < X < 48 ] = 0,9544 or 95,44%

Step-by-step explanation:

z = ( X - μ₀ )/σ

μ₀ the mean ( average no. of months that an employee stay in a factory)

σ standard deviation

a) P [X ≥ 30 ] = 1 - P [X < 30 ]

P [X < 30 ]

We look for z (score)

z = ( X - μ₀ )/σ ⇒ z = 30 - 36 / 6

z = - 1

From z table we get for -1

P [X < 30 ] = 0,1587

And

P [X ≥ 30 ] = 1 - P [X < 30 ] ⇒ P [X ≥ 30 ] = 1 - 0,1587

P [X ≥ 30 ] = 0,8413 or 84,13%

b) P [X < 24]

z (score) = ( 24 - 36 ) / 6

z( score) = -2

And from z table we get:

P [X < 24] = 0,0228 or 2,28 %

c) P [ 24 < X < 48 ] is P[X ≤ 48] - P[X ≤ 24]

P [X < 48]

s (score) = 48 - 36 / 6 ⇒ z = 2

P [X < 48] = 0,9772

Then

P [ 24 < X < 48 ] = 0,9772 - 0,0228

P [ 24 < X < 48 ] = 0,9544 or 95,44%

Just the picture, Geometry.

Answers

The correct options are :-

Option (b) x + y = 180 Option (c) y = z Option (d) x + z = 180

Option b is correct because angle x and y will add up to 180° as they are a linear pair . Option c is correct because angle y and angle z are vertically opposite angles . Option D is correct because angle x and angle z are a linear pair .

A group of local organizers, led by a prominent local businesswoman, would like to use the pavilion for a concert to benefit a non-profit, national network of investors and environmental organizations working with companies and investors to address sustainability challenges such as global climate change. If the pavilion management agrees to host the concert, the organizers will donate all profits to Ceres (or absorb any losses).Based on the following revenue and cost information, the organizers would like answers to several questions.1. There are three sources of revenue for the concert:2. Tickets will be sold for $15.50 each.3. A large multinational corporation headquartered in Chicago will donate $2.00 per ticket sold.4. Each concert attendee is expected to spend an average of $17.00 for parking, food, and merchandise.5. On the expense side, there are also three components:A popular national group has agreed to perform at the concert. Normally, the group demands a significant fixed fee to perform, but to reduce the risk for the organizers, the group has agreed to perform for $6.00 per ticket sold. The organizers will pay several companies to operate the parking, food, and merchandise concessions. They will pay $21,000 plus 15% of all parking, food, and merchandise revenue. The organizers will pay the pavilion $85,000 plus $7.00 per person attending to cover its operating expenses (production, maintenance, advertising, etc.)Required:a.

Assuming a tax rate of 31% on profits from the concert, what must dollar ticket sales be in order for after-tax concert profits to be $100,000?f.

If the organizers expect to sell 10,500 tickets, how much can they afford to pay and still earn a profit of $100,000 (ignore taxes)? HELP.
