Hello all!
If you get this correct (it shows) I will give you brainlest 5 stars and thanked every day!

Answer:

Answer is D.

30

Step-by-step explanation:

all angles add up to 180(applys to triangles)

20000 = 100% so we need to find 1% first so we can find the 40% that will be accepted

20000 : 100 = 200 (that's 1%)

to find 40% we multiply 200×40= 8000 people accepted

we need to find the 25% of those 8000 so again we divide by 100

8000 : 100 = 80

80 × 25 = 2000 people

hopefully it's correct good luck

Answer: Volume of the cone = 47.12 cubic feet.

Step-by-step explanation:

You didn't finish the question so Idid the best with what I had, you also didn't include the image that I think was supposed to be included.

To solve for the full volume including the cylinder, use the cylinder's volume formula.

Volume of a cylinder = height (pi) (r^2) and then add it to the 47.12.

Volume of a cone is pi(r^2)(h/3)

plug and chug!

h stands for height and r stands for radius.

Answer:

it would be x>-18

Step-by-step explanation:

Answer:

x > −18

Step-by-step explanation:

Move all terms not containing xx to the right side of the inequality.

−2x<36-2x<36

Divide each term by −2-2 and simplify.

x>−18x>-18

The result can be shown in multiple forms.

Inequality Form:

x > −18

Answer:

An equation in the slope-intercept form will be:

[tex]y=\frac{-1}{2}x+0[/tex]

Step-by-step explanation:

Given the points

Finding the slope between points

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(4,\:-2\right),\:\left(x_2,\:y_2\right)=\left(2,\:-1\right)[/tex]

[tex]m=\frac{-1-\left(-2\right)}{2-4}[/tex]

[tex]m=-\frac{1}{2}[/tex]

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept.

substituting the values m=-1/2 and the point (4, -2) to determine the y-intercept i.e. 'b'.

[tex]y=mx+b[/tex]

[tex]-2=\frac{-1}{2}\left(4\right)+b[/tex]

[tex]-2+b=-2[/tex]

[tex]b=0[/tex]

substituting the values m=-1/2 and b=0 to determine the line equation in slope-intercept form

[tex]y=mx+b[/tex]

[tex]y=\frac{-1}{2}x+0[/tex]

Thus, an equation in the slope-intercept form will be:

[tex]y=\frac{-1}{2}x+0[/tex]

Answer:

For the table on Q3, the constant rate of change should be 20(?)

Step-by-step explanation:

I believe the answer should be 20, as each increment in the graph that crosses through 2 whole numbers is by 20, meaning that it goes from (20,5) to (40,10), and so on and so forth.

If this is not the correct table, please respond to this comment and say so. Thanks in advance.

Answer:

She should apply the discount first.

Step-by-step explanation:

Giving the following information:

Selling price= $89

Discount rate= 12%

Coupon= $10

When you apply a percentage to increase or decrease a nominal number, the higher the number bigger the percentage. Therefore, first, we need to apply the percentage discount and the coupon.

We will demonstrate:

Discount percentage first:

Discount= 89*0.12= $10.68

Coupon= $10

Purchase price= 89 - 10.68 - 10

Purchase price= $68.32

Coupon first:

Coupon= $10

Discount= (89 - 10)*0.12= $9.48

Purchase price= 89 - 10 - 9.48

Purchase price= $69.52

The value of x = 7

Step-by-step explanation:

Given the expression

[tex]-3-\left(-8\right)-\left(-2\right)\:=\:x[/tex]

switch sides

[tex]x=-3-\left(-8\right)-\left(-2\right)[/tex]

[tex]\mathrm{Apply\:rule}\:-\left(-a\right)=a[/tex]

[tex]x=-3+8+2[/tex]

[tex]\mathrm{Add/Subtract\:the\:numbers:}\:-3+8+2=7[/tex]

[tex]x=7[/tex]

Thus, the value of x = 7

Given :

We have $100 in our saving account and plan to deposit $12.50 each month.

Cost of 10 acres of land in mars is $175.

To Find :

How many months will it take you to save enough money to buy 10 acres of land on Mars.

Solution :

Let, after n months amount in account is :

[tex]A = 100 + 12.50n[/tex]

This A should be greater than equal to $175.

A ≥ 175

100 + 12.50n ≥ 175

n ≥ 75/12.50

n ≥ 6

Therefore, it will takes 6 months to collect such amount.

Answer:

Step-by-step explanation:

2x + 2x + 72° = 180°

4x = 108°

 x = 27°

Answer:

x = 27

Step-by-step explanation:

Because lines AC and DE are parallel, angles ABD and CDE are equal.  Therefore angle BDE is 72.  Angle ADF is a straight angle, so 2x + 72 + 2x = 180, or 4x = 108, 2x = 54 and x = 27.
