Answer:

Step-by-step explanation:

Okay, so adding negative numbers can get very tricky, but I think I can help

Since there are two negative signs next to each other, they both cancel out and become positive so instead you get

-2+7

And if you do this with a number line, if you start and negative 2 and keep going right 7 times, you get 5

I hope I helped! I know negative numbers can be really difficult, but once you get the hang of it I bet you'll be great!

The line rises to the left so the slope is negative.

Slope = rise / run = (3 - 1) / (-4-3) = 2 / -7

In the diagram, a building cast a 35-ft shadow and a flagpole casts an 8-ft shadow. If the the flagpole is 18 ft tall, how tall

xxTIMURxx [149]

Answer: 78.8 ft

Step-by-step explanation:

Similar triangles have proportional sides.

$\dfrac{\text{building shadow}}{\text{building height}}=\dfrac{\text{flagpole shadow}}{\text{flagpole height}}\\\\\\\dfrac{35}{\text{building height}}=\dfrac{8}{18}\\\\\\\dfrac{35\times 18}{8}=\text{building height}\\\\\\\dfrac{35\times 9}{4}=\text{building height}\\\\\\\dfrac{315}{4}=\text{building height}\\\\\\\boxed{78.75=\text{building height}}$

sineoko [7]

Answer:

A. 96π in³

Step-by-step explanation:

The formula you can use to find the volume of a cone is ...

V = (π/3)r²·h . . . . where r is the radius and h is the height

Put the given numbers into the formula and do the arithmetic.

V = (π/3)(6 in)²(8 in) = 96π in³

Answer:

200 rounded to the nearest hundredth

Step-by-step explanation:

Acute is about 30 degrees so 30+30=60

so a right angle is 90 degrees right so 90 + 60 =150 round it to the nearest hundredth and you have 200 that's how i got my answer :))
