Answer:

40 degrees

Step-by-step explanation:

Because there are 180 interior angles in a triangle, you need one of the sides. If an angle's exterior is 40 degrees, we know that the interior angle is 140 degrees. This means that the sum of the other interior angles have to be 40 as 180-140 is 40.

calculate the volume of each cone. Use 3.14 for π. Round answers to the nearest hundredth if necessary.

coldgirl [10]

Answer:

2355 cm^2

Step-by-step explanation:

The volume of a cone is given by

V = 1/3 pi r^2 h

V = 1/3 (3.14) (15)^2 (10)

V =2355

PLZ HELP WITH THIS QUESTION!

Bad White [126]

Answer:

D

Step-by-step explanation:

Given the quadratic

d = - 16t² + 12t ← subtract d from both sides

- 16t² + 12t - d = 0 ← in standard form

with a = - 16, b = 12, c = - d

Use the quadratic formula to solve for t

t = ( - 12 ± $\sqrt{12^2-(4(-16)(-d))}$ ) / - 32

= ( - 12 ± $\sqrt{144-64d}$ ) / - 32

= ( - 12 ± $\sqrt{16(9-4d)}$ ) / - 32

= ( - 12 ± 4 $\sqrt{9-4d}$ ) / - 32

= $\frac{-12}{-32}$ ± $\frac{4}{-32}$ $\sqrt{9-4d}$

= $\frac{3}{8}$ ± $\frac{1}{8}$ $\sqrt{9-4d}$

= $\frac{3}{8}$ ± $\frac{\sqrt{9-4d} }{8}$ → D

You roll 2 dice. how likely is it that the 2 numbers will add up to 12 or less?

VashaNatasha [74]

It is a very high probability. If you role two dice no matter what you will get 12 or less.
