Answer:

Use Desmos for the graphs, symbolab for the inequalities answers.

Step-by-step explanation:

1.07 = 1 + 0.07 = 100% + 7%

An example would be say you start off with 100 items. Multiply this with 1.07 and you should get 107 as a result, which is an increase of 7% (note how 7% of 100 = 7)

Answer: 4.55 inches of rain

Step-by-step explanation: Is this a trick question? It's a lot easier than it looks...but i'll give you a step by step explanation.

So, we know is 4.5 hours it collect 2.8 inches of rain, must have been a rainy day.

The next day the gauge collect 1.75 inches of rain, it must have sprinkled a little.

2.8 + 1.75 = 4.55

Therefore, the guage collected 4.55 inches of rain in total.

I hope this helps!

Answer:

[tex]176.25inches^{2}[/tex]

Step-by-step explanation:

The formula for the area of the triangle is : [tex]\frac{base*height}{2}[/tex]

To work this out you would first need to break the shape down into 4 smaller triangles.

Then you would need to work out the area of the triangles. You can do this by multiplying the base by the height and dividing it by 2. We will first work out the area of the first triangle  at the top. To work out the area you would multiply the base of 7.5 by the height of 7.5, this gives you 56.25. Although the formula says you should divide the answer by 2 however as there are two identical triangles this action does not need to be done.

The next step is to work out thew area of the bottom triangles. To do this you would multiply the base of 7.5 by the height of 16, this gives you 120.

Now that we have found the area of both sides of the kite we can now add the values of 56.25 and 120 to work out the full area of the kite, this gives you 176.25 square inches.

1) Break the kite into smaller triangles.

2) Work out the area of the triangles at the top.

[tex]7.5*7.5=56.25[/tex]

3)Work out the area of the triangles at the bottom.

[tex]7.5*16=120[/tex]

4) Add the area of both sides.

[tex]56.25+120=176.25inches^{2}[/tex]

Take a point on the graph and use rise over run method

Answer:

Step-by-step explanation:

You can find the slope by picking a point such as (8,5).

Slope = rise over run.

(8,5) is 8 units right and 5 units up, thus the slope is 5/8

Answer:x=57

Step-by-step explanation:

Answer:

30.5

Step-by-step explanation:

Measure of angle A and B equals 110 because of how triangles work

Therefore 3x + x + 4 = 110

4x + 4 = 110

Subtract 4 from each side

4x = 106

Divide both sides by 4

x = 26.5

Measure of angle ABC equals 26.5 + 4 = 30.5

Answer:

15.8

Step-by-step explanation:

The formula would be V = Bh, the Base being LxW.

Since we already know the base and volume, we can substitute it into the formula.

306.52 = 19.4(h). Divide by 19.4, and you get 15.8 as your answer.

Hope that helps! Tell me if im worng, im only a student .m.

Answer:

The area of the base is 14.5π in²

Step-by-step explanation:

The volume of a cylinder is given by

Volume =base\:area \times height

Or

V=Bh

It was given that the volume of the cylinder is 174π in³.

The height was given as 12 inches.

We substitute to get,

174π=12B

Divide both sides by 12 to get:

B=14.5π in²

Hence the area of the base is 14.5π in²

Answer:

area of base =  14.5π in²

Step-by-step explanation:

the area of the base of a cylinder with a volume of 174π in^3 and a height of 12 inches is found by applying the formula for the volume of a cylinder:

V = πr²h

Here  the area of the base of a cylinder with a volume of 174π in³ and a height of 12 inches, and so:

V = πr²(12 in) = 174 π in³

Dividing both sides by 12 in isolates πr², which is the area of the base:

                                   174π in³

area of base = πr² = --------------- = 14.5π in²

                                     12 in

Step-by-step explanation:

at least I tried

Answer: 3

Step-by-step explanation:

37.5 (3.8-x) + 90x = 300

First, you have to simplify, by using the Distributive Property.

142.5 - 37.5x + 90x = 300

Now, add the like terms

142.5+ 52.5x = 300

Now, isolate the variable, meaning the variable has to be on one side on its own. You would have to subtract 142.5 and move it to the other side

52.5x = 300 - 142.5

52.5x = 157.5

Then, you divide!

[tex]\frac{52.5x}{52.5x}[/tex] = [tex]\frac{157.5}{52.5x}[/tex]

= 3

Answer:

9x -6

Step-by-step explanation:

The correct option is D.

We name the Algebra Tile pieces by considering the area of each, meaning we need to know the dimensions of each piece. If the small yellow square has a length of 1 unit, the area of the small square is 1 square unit. Then the long green rectangle has dimensions 1 by x and has an area of x square units.

Algebra tiles are square and rectangle-shaped tiles or tiles that represent numbers and variables. For example, we can use square tiles to represent numbers. Each square tile is equal to one. So, four can be represented by four square tiles.
