2x+4 is an alternate angle to the angle opposite on the top left to 5x+8

Which means (2x+4)+(5x+8)=180

So add both together to get

7x+12= 180

Then subtract 12 from 180

7x=168

then divide 168 by 7 to get

How can you divided a fractions

Answers

Answer:

I have explained below

Brief explanation:

To divide fractions take the fraction you're dividing by and turn it around. Then replace the division sign with a multiplication sign.

This is how it works - I'll illustrate with an example

$\frac{1}{2} :\frac{2}{3}$

$\frac{1}{2} : \frac{3}{2}$

$\frac{1}{2} *\frac{3}{2}$

now just multiply over

$\frac{1*3}{2*2}$

$\frac{3}{4}$

the volume of the right circular cylinder in 144π cubic yards. if h, the height of the cylinder is 4 yards, what is r, the radius of the base?

the volume of the right circular cylinder in 144 cubic yards. if h, the height of the cylinder is 4 yards,

Answers

The volume of a right circular cylinder is given by the formula V = πr^2h, where r is the radius of the base and h is the height of the cylinder.

If the volume of the cylinder is 144π cubic yards and the height of the cylinder is 4 yards, you can set up the equation:
144π = πr^2 * 4

You can then solve for r by dividing both sides of the equation by 4π:
r^2 = 36
r = 6

Thus, the radius of the base of the cylinder is 6 yards.

Answer:

r = 6

Step-by-step explanation:

The formula for the volume of a cylinder is V = πr^2h,

If the volume of the cylinder is 144π cubic yards and the height of the cylinder is 4 yards it can be written as 144π = πr^2 * 4

You can then solve for r by dividing both sides of the equation by 4π:

r^2 = 36

r = 6

Daniel is a piano instructor who gives lessons on weekends. The cost of one lesson is $30. Daniel is offering a 5-lesson package with a 25% discount off the total price.

How much would a student save by buying a multi-pack compared to 5 separate lessons?

Why would Daniel offer a discount when he knows he could earn more money selling the lessons separately?

Answers

Answer:

150 is if you buy them separately but 150-25%=112 so 150-112=38 so students would save $38

Step-by-step explanation:

he made that package so that more people would go to his lessons know that there was a discount going on and more people would choose his lessons over people who don't have discounts.

Answer:

1- Separately - 150

A project will take a total of 720 person-days to complete. If the project must be completed in 30 days, how many people must be employed? PLEASE HURRY

Answers

Answer:

192 hours per day / 8 hours per person per day = 24 people

Step-by-step explanation:

Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:

720 person-days x 8 hours = 5,760 hours

To complete the project in 30 days, the total number of hours needed per day is:

5,760 hours / 30 days = 192 hours per day

It’s 24!! EXPLAIN-720/30=24 because you have to divide the amount of people by days p/d= e

Hozumi and Petra each own a hybrid car. They decide to compare the gas mileage for each, and kept track of the weekly average fuel efficiency (in mpg, miles per gallon) for a period of 8 weeks. The results are shown in the tables.

a. 1.45
b. 2.25
c. 3.92
d. 5.37

Answers

Answer: 1.45

Step-by-step explanation

It probably should be 1.45 I suppose since if you look at the graph, there is 3 - 39 and in the second, 3 - 52 so if you divided 39 by 3 you'd get 14 and if you divided 52 by 3 you'd get 17.3333333 and if you divided 17.3333333 by 14, you'd get 1.23809523571, which is closest to 1.45. I think that this is probably the answer.

it should 1.45 I’m pretty sure at least

Answer:

A = plane

B = whale

C = sunken ship

Step-by-step explanation:

The given vertical number line is modelling the positions of objects and animals in relation to sea level.

Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.

From inspection of the given number line:

Position A is above sea level.Position B is just below sea level.Position C is the furthest below sea level.

We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.

We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

A is plane b is whale c is sunken ship

if a coin is flipped and a fair die is rolled 96 times, predict how many times you would flip a head and roll a 6

Answers

Answer:

Step-by-step explanation:

on flipping a coin, we either get a heads or a tails and both the events are equally likely. So the probablity of getting a tails is 1/2.

Now

On rolling a die, we can get 6 possible outcomes(1,2,3,4,5,6)

But the favourable outcomes (an even number) are only 3. So the probablity of getting an even number is 3/6=1/2

In case. we have 2 events that need to occur together, we simply need to multiply their individual probablities to get the probablity of getting both the events together

So our required answer is

p(even number)× p(tails)= 1/2 × 1/2 = 1/4

The answer is b explanation I asked my math teacher on mine

1.Let k be a positive real number. The line x + y = k and the circle x^2 + y^2 = k are drawn. Find k so that the line is tangent to the circle.

2.Let A = (6,2), and let B be the reflection of A over the line y = 1/2x + 5. Find the coordinates of B

Answers

1. The line x + y = k has a slope of -1. Therefore, the line perpendicular to it that passes through the center of the circle x^2 + y^2 = k has a slope of 1. The center of the circle is (0, 0), so the equation of the line perpendicular to x + y = k that passes through (0, 0) is y = x. Solving the system of equations x + y = k and x^2 + y^2 = k, we get two solutions: (k/2, k/2) and (-k/2, -k/2). Since the line y = x is tangent to the circle at (k/2, k/2), we have k/2 + k/2 = k, which gives k = 2.

2. The line y = 1/2x + 5 has slope 1/2, so the line perpendicular to it that passes through A = (6, 2) has slope -2. The equation of this line is y - 2 = -2(x - 6), which simplifies to y = -2x + 14. To find the reflection B of A over the line y = 1/2x + 5, we need to find the intersection of the line y = -2x + 14 and the perpendicular bisector of the segment AB. The midpoint of AB is ((6 + x)/2, (2 + y)/2), and the slope of AB is (y - 2)/(x - 6). Therefore, the slope of the perpendicular bisector of AB is -1/(y - 2)/(x - 6), which simplifies to (6 - x)/(y - 2). The equation of the perpendicular bisector of AB is y - (2 + y)/2 = (6 - x)/(y - 2)(x - 6)(x - (6 + x)/2) + (2 + y)/2. Solving the system of equations y = -2x + 14 and y - (2 + y)/2 = (6 - x)/(y - 2)(x - 6)(x - (6 + x)/2) + (2 + y)/2, we get B = (5, 8). Therefore, the coordinates of B are (5, 8).

Leon is scuba diving at an elevation of −72
feet when his friend signals to come higher to see a sea turtle. Leon makes 3 ascents, each an equal distance, to reach an elevation of −18
feet, where the sea turtle is located.

What was Leon's elevation after his second ascent?

Answers

Answer: -36 feet

Step-by-step explanation:

72-18 = 54 feet ascended

54 feet / 3 ascents = 18 feet per ascent

18 feet * 2 ascents = 36 feet

-72+ 36 = -36 feet

After his second ascent Leon was at an elevation is -36. Step by step; 72-18= 54
54/3= 18, 18*2=36
72-36= 36
