QUESTION POSTED AT 10/10/2019 - 09:39 AM

It is the third one that is the answer i think

8x+17 >/ -7

-17 both sides

8x >/ -24

÷8 both sides

x >/ -3

x is GREATER THAN or equal to -3

since it is or equal to the circle is closed

the arrow goes the the right (bottom left number line is the answer)

-13 <-5x-28

+5x both sides

5x-13 <-28

+13 both sides

5x <-15

÷5 both sides

x < -3

x is less than -3

since there is no or equal to the circle is open

the arrow goes to the left (bottom right number line is the answer)

-17 both sides

8x >/ -24

÷8 both sides

x >/ -3

x is GREATER THAN or equal to -3

since it is or equal to the circle is closed

the arrow goes the the right (bottom left number line is the answer)

-13 <-5x-28

+5x both sides

5x-13 <-28

5x <-15

QUESTION POSTED AT 17/10/2019 - 09:16 AM

Hey there!

For this problem and future problems like these, you'll want to memorize the phrase "SOHCAHTOA," which indicates which sides of the triangle are equal to which trigonomic function.

Sine = Opposite/Hypotenuse

Cosine = Adjacent/Hypotenuse

Tangent = Opposite/Adjacent

Based on that, you need to know which sides on the triangle are which. I attached an image for reference. The image I attached references the right angle, however, you'll want to reference angle A on your triangle instead, based on the problem.

Based on that, you should be able to easily divide your numbers and get your answer.

Hope this helped you out! :-)

TRUE. I'm going to be using a picture from Google to help me out. In the graph below the line plots are telling how much Sarah's is as the years past. Each line plot tell the data of how much her car cost in whatever year the plot is in. For example, in 2006 her car cost $10,000. How do we know? We know this because the line plot is point towards 10,000 and downwards to 2006. This is data that the line plots are displaying fro us.So yes, line plots do display individual data.

It looks like for all of these we will be using the Pythagorean theorem.

If you don't know what this is or how to apply it, go to the website**"Khan Academy"** and watch his video(s) on it. I would suggest going to that site whenever you don't understand something in math :)

I'll just be giving you the answers and won't explain what I'm doing, but**please do go to Khan Academy to find out how to do it on your own!!**

Anyway, onto the answers.

1) a = 12.5, b = 5.7, c = 13.7.

2) 24

3) 19.2

4) 6.4

5) 18.7

6) 98.5

7) 1.9

Hope this helps!!!

QUESTION POSTED AT 17/10/2019 - 09:07 AM

The shaded region is the area of the circle minus the area

of the pentagon.

A circle = pi * r^2

A circle = pi * 15^2

A circle = 706.5 cm^2

A regular pentagon = (a * p)/2 where a is the apothem, p is the perimeter.

The apothem id the perpendicular height from the midpoint of a side to the center of the pentagon.

To find the apothem you have to use a trig ratio.

A pent = (8.3 * 12*5)/2

A pent = 249 cm^2

Shaded region: circle - pentagon 706.5 - 249 = 457.5

of the pentagon.

1350 > 1280 so answer is Amanda

Q2) 70 cm^3

1350 - 1280 = 70
