Answer:

Cone or Cylinder, Sphere

Step-by-step explanation:

Answer: The surface area of a cone can be found by drawing a net and adding the area of all their respective two - diamasional surface. Use the formula 4πr2 to find the surface area of a Sphere where r is the radius of the figure.  

Step-by-step explanation:

Answer:

20 units

Step-by-step explanation:

1) find the side of the first square

side = P / 4 = 12:4 = 3 units

2) find the side of the second square

side = P / 4 = 16 : 4 = 4 units

3) use the Pythagorean theorem to find the hypotenuse of the right triangle

[tex]\sqrt{4^2 + 3^2} = \sqrt{16 + 9} = \sqrt{25} = 5[/tex] units

4)  find the perimeter of the third square

P = side x 4 = 5 x 4 = 20 units

Answer:

20 units

Answer:

A Jenna

Step-by-step explanation:

Because if Jenna received 22% votes and Jordan, Kelsey, Nathan received less 20 percentage that means Jenna won for school president.

Answer:

b

Step-by-step explanation:

the y-intercept is 41 so and the year 1945 is x=0

How to:

30 x 10 is half of how to find the triangle part which is 300 therefore the other half is also 300 to together it is 600. Now for the rectangle part, it's 10 by 20 which is 200. Therefore, we add the totals of both making the answer. But DONT forget the lables since all these mesurements are in square inches!!

Answer:

800 sq inches

Answer:

Javier estimates the square root of 18 in the following way: √18=2√9=2*3=6 Explain why her reasoning is incorrect. Without using a calculator, the square root of 18 will be between what two values (remember to look for perfect squares/perfect square roots)? Show your reasoning. You do not need to find the decimal equivalent of the root.

Answer:

a.

Step-by-step explanation:

by elimanation,cimparison or substitution you wull get the value of x=-60/17 and y=6/17

Answer:

1/1

Step-by-step explanation:

x1 subtracted by x2

in this case 3-2=1

Then y1 subtracted by y2

5-4=1

y will be put over x in fraction form

Answer:1/1

Answer:

mark her as brainliest

Step-by-step explanation:

Answer: D / none are true

Since it's proportional (it's a straight line), B and C are automatically wrong. A would seem true at first glance, BUT if you look closely at the graph, the slope of the graph is actually 2x.

Look at the beginning of the line. It starts at 18 (x = 0/y intercept) and at x = 1, you can see that y is at 16. The y value goes down by 2 every time x increases by 1. This means that the equation of the graph is -2x + 18 = y.

The graph is proportional and has an equation of y = -2x + 18. This means that A, B and C are incorrect.

Answer:

Step-by-step explanation:

It is a straight line also known as proportional. The first impression, A appears to be accurate, but closer inspection reveals that the graph's slope is actually 2x. 18 (x = 0/y intercept) and ends at x = 1, where little y is at 16. Any time x expands by one, the y value falls by two. This says that the graph's equation is -2x + 18 = y.

Answer:

C. 6.75n = 114.75

Step-by-step explanation:

The store collects $114.75, each magazine is 6.75, the number of magazines is shown by n.

Answer: The answer is A.

It is A because you have to divide the total by the cost to find out the amount of magazines purchased.

Answer:

D. m/_ 4 is 137

Step-by-step explanation:

If you add 137 and 43 you get 180 which is the line's angle.

Answer:

134 square inches

Step-by-step explanation:

To find surface area, you must find the individual area of each face of the shape. There are 6 faces on every cube or other rectangular prism, so you must perform 3 equations, as every face has an identical face on the opposite side. The formula for regular area is Length (l) times Width (w).

Large sides on front and back: 8x6=48

Slim sides to the right and left: 1x6=6

Slim sides on top and bottom: 8x1=8

Then combine:

48+48+6+6+8+8=134

Answer:

C.

Step-by-step explanation:

I learned this years ago, but I think it's answer C. Because the others (curved lines) would be classified as Non-linear.

*(( I sincerely apologise if this turns out to be the wrong answer. Lol))

Answer:

C

Step-by-step explanation:

When you see the word "linear," think "line."  Only one of the four given graphs is a straight line:  C

Answer:

Where's the rest of the question?

Answer:

11. 10x^2 - 13x - 3

12. 5x^2 + 18x + 5

Step-by-step explanation:

11. Product means multiplication, so you can multiply (5x + 1) and (2x - 3).

[tex](5x + 1) * (2x - 3)[/tex] - Using the FOIL (First+Outer+Inner+Last)

So: [tex](5x*2x) + (5x*-3) + (1*2x) + (1*-3)\\10x^{2} -15x + 2x -3\\10x^{2} -13x -3[/tex]

12. [tex]3x^{2} + 8x - 1 + 2(x^{2} +5x + 3)[/tex] (So, you distribute the 2 to x^2 + 5x + 30, then combine like terms).

[tex]3x^{2} + 8x - 1 + 2(x^{2} +5x + 3)\\3x^{2} + 8x - 1 + 2x^{2} +10x + 6\\(3x^{2} +2x^{2}) + (8x + 10x) + (-1+6)\\5x^{2} + 18x + 5[/tex]

Hopefully, this helped you. Good luck & have a good day!
