An appliance company uses the function f(h) = 40h + 120 to calculate the total repair bill, f(h), for h number of hours worked. Find h if f(h) = $200.

Answers

Answer 1

Answer:

fh. = 40h + 120,  fh. = $200

200 = 40h + 120

200 - 120 = 40h

80 = 40h

80/40  = h

 2 = h

h = 2 hours.

The results from a random sample of 150 students' after-school activities at a school are shown. 68 students prefer soccer. 59 students prefer basketball. 23 students prefer swimming. Part A If there are a total of 500 students in the school, what is the best approximation for how many students in the school prefer basketball? 197 students 197 students 227 students 227 students 295 students 295 students 303 students 303 students

Answers

Answer:

≈ 197 students

Step-by-step explanation:

Let's start by writing what we know.

150 students sampled

68 prefer soccer

59 prefer basketball

23 prefer swimming

Part A

If 59 students prefer basketball out of the 150 students sampled then we divide 59/150 in order to get the percentage of students that prefer basketball.

59/150 ≈ 39.33%       Remember this is only a sample of the students so it is approximate.

Now that we have the percentage, we can multiply it by the entire student body to get an approximate number of all students that prefer basketball.

39.33% = .3933

.3933 * 500 = 196.66  ≈ 197 students   (because we can't have a partial student we round up)

The best approximation of the number of students in the school who prefer basketball is 197.

What is the percentage?

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

The results from a random sample of 150 students' after-school activities at a school are shown.

68 students prefer soccer. 59 students prefer basketball. 23 students prefer swimming.

The percentage of students who prefer soccer will be

[tex]\rightarrow \dfrac{68}{150} = \dfrac{34}{75}[/tex]

The percentage of students who prefer basketball will be

[tex]\rightarrow \dfrac{59}{150}[/tex]

The percentage of students who prefer swimming will be

[tex]\rightarrow \dfrac{23}{150}[/tex]

If there are a total of 500 students in the school. Then the best approximation for how many students in the school prefer basketball will be

[tex]\rightarrow \dfrac{59}{150} \times 500 = 196.667 \approx 197[/tex]

The elevation of lake sam rayburn is 164 above mean sea level during the summer if it does not rain the elevation of the lake decreases by 0.5 feet each week

Answers

Answer:

I guess that you want to model the elevation of Lake Sam Rayburn.

During the summer, it is 165 ft above the sea level (the sea level is our position 0ft).

If it does not rain, the elevation of the lake decreases by 0.5ft each week.

So if we assume that there is no rain, we can write the elevation fo the lake as a linear relationship with slope equal to -0.5ft and y-intercept equal to 165ft.

L(w) = 165ft - 0.5ft*w

Where w is the number of weeks without rain, if we have 0 weeks without rain, then the level of the lake remains constant at 165ft above sea level,

L(0) = 165ft - 0.

Find the complement and supplement of the angle with measure 40 degrees

Answers

Answer:

The complement is 50 and the supplement is 140

Step-by-step explanation:

Complementary angles add up to 90. Supplementary angles add up to 180. We simply need to subtract to find the difference to fill the gap.

90-40=50

180-40=140

The complement is 50 and the supplement is 140

Answer:

complement angle to 40 degrees is 50 and the supplement angle to 40 degrees is 140

Step-by-step explanation:

complement angle to 40 degrees is 90 - 40 = 50 degrees

Supplement angle to 40 degrees is 180 - 40 = 140 degrees.

The area of a rectangle is (x2 - 5x - 36). What is the width if the length of the rectangle is (x + 4)?

Answers

Answer:

Step-by-step explanation:

The width of the rectangle is (x - 9)

(x + 4)(x - 9)

x^2 - 9x + 4x - 36

x^2 - 5x - 36

Answer:

W = ( x - 9 )

Step-by-step explanation:

The area of a rectangle is equal to the length times the width of the rectangle.

So we can say A = LW

A = (x^2 - 5x - 36)

L = (x + 4)

A = LW

W = A / L

W = (x^2 - 5x - 36) / (x + 4)

W = (x + 4) (x - 9) / (x + 4)

W = (x - 9)

question is givenin the photo given above​

Answers

Step-by-step explanation:

In order to meet at point F, line DF must travel from the top line to the bottom line. If it crosses through E, the midway, that means that it is halfway to the bottom line. This means the distance D E is equal to E F, because both are the distance from midpoint E to one of the sides (top or bottom).

If D E and E F are equal length, then AB and BF must be the length as well, as it is the length DF line takes to get halfway down from the top. Since they are the same length, A F must be twice the length of AB.

I’m sorry to say that this graph is not correct.

The formula for the graph that you just graphed is y=-x-7. The graph, x=-7 should just be a vertical line going through the point (-7,0).

So the good news is you did get the first point correct, the bad news is that second point is not making the entire graph wrong.

Here’s a trick that always helped me, any question asking me to graph x=(a number) the line will always be vertical, and if the question asked me to graph y=(a number) the line will always be horizontal.

Will mark brainest

Answers

Hello there! :D

Firstly, I want you to understand an important concept. This has something to do with absolute value. So, although distance is a number, it is neither positive nor negative. It does not necessarily involve value. So, what we are looking for today will not have a negative sign in front of it. We are simply looking for distance!

Let's start with ST, because the distance between those is smaller and therefore I can better explain this to you. T is at the point 19.1, and S is at the point 14. We need to find the amount of distance between the two. How do we do that?

Subtraction! In order to find this value we can subtract the smaller number from the larger number.

19.1-14= 5.1

ST is 5.1

Now we can look at the distance between TR. We are actually going to add numbers together! We know that T is 19.1. If we were to put a dot at zzero and measure that distance, it would be 19.1. What is the distance from R to zero? That's right! The same principle is there. If we had a dot at zero and we're measuring from 4, the distance would be 7.5 (even though it is negative on the number line).

So, we can add these numbers together!

19.1+7.5= 26.6

TR is 26.6

I hope this helped you and you have a wonderful day,

Bill: 150, 154, 158, 162, 166, 170, 174

As you can see here, after 5 months, they will have the same weight.

Give three examples of objects that have potential energy

Answers

Answer:

A car parked on a hill, A raised weight, A snow pack.

Step-by-step explanation:

To summarize, potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.

Three examples of objects that have potential energy are,  a child at the top of the seesaw in play-ground, water in dam, rock kept at some finite height of hill.

What is Potential Energy ?

The energy possessed by a body due to its position or configuration is known as potential energy. when an object is at rest, velocity is equal to zero, thus velocity of the object doesn't contribute to potential energy, it only depends upon gravitational constant "g", height h of the object above the Earth's surface and mass m of the object.

The basic formula to determine the Potential Energy possessed by the body is given by :

P.E = mgh

examples of objects that are having potential energy are :

1) a child at the top of the seesaw in play-ground.

2) water in dam.

3) rock kept at some finite height of hill.

caroline is taking a road trip on 1-70 in kansas. she stops for gas at mile marker 36. her destination is at mile marker 353 in topeka, but she decides to stop at an attraction 3/4 of the way after stopping for gas. at about which mile marker did caroline stop to visit the attraction.

BTW not middle school

Answers

Answer:

274

Step-by-step explanation:

First stop of Caroline = At 36 mile marker

Destination of Caroline = At 353 mile marker

Distance left to be covered = 353 - 36 = 317 miles

Given that Caroline decides to stop at an attraction [tex]\frac{3}{4}[/tex] of the way after she stops for gas.

i.e. at a distance [tex]\frac{3}{4}[/tex] of 317 miles away from the Gas stop.

[tex]\frac{3}{4} \times 317 = 79.25\times 3 \approx 238\ miles[/tex]

So, Caroline stops at a point which is around 238 miles away from the gas station.

To calculate the Mile marker of her stop, we need to add the mile marker of gas station and the distance of her stop from gas station.

Mile marker location at her stop = 36+238 = 274

Conservatives wanted to keep a Catholic monarchy in control and reformists wanted a state with elected representatives. This political clash of ideas spilled into the streets as many people demanded change and police arrested many in an attempt to keep the peace. In 1936, the conflict reached a boiling point. The new prime minister sent some military officers away from the mainland, fearful that they were conspiring to overthrow the government. One of these officers was sent to the Canary Islands, off the coast of Africa. His name was General Francisco Franco. He immediately took control of the islands, then flew to Morocco and assumed control there. The takeover of Spain by the military was supposed to be quick, but the government found out about it and civil war broke out. The war lasted from 1936 until 1939 when Franco declared victory after much suffering and bloodshed. There were many terrible things done on both sides of the conflict. One of those was the bombing of a small Basque town called Guernica. The attack destroyed nearly the entire city, and there were many casualties. A Basque man named Jos Antonio Aguirre testified: Before God and before History which must judge us all, I affirm that for three and one-half hours, German planes bombarded with unheard-of fury the defenseless civilian population of the historic city of Gernika, reducing it to ashes, chasing with machine-gun fire women and children who perished in great number, fleeing the stampede of others driven mad by panic. Guernica soon became a world-famous symbol of the suffering of innocents during war. This inspired Pablo Picasso, a famous Spanish painter, to create his famous painting: Guernica.
