ANEK [815]3 years ago
7 0

Answer:

we conclude that Kiera got the right 63 questions.

Step-by-step explanation:

Total questions = 90

The percentage of correct question = 70%

Using the formula

The number of correct questions = 70% of 90

                                                         = [70/100] × 90

                                                          = 0.7 × 90

                                                           = 63

Therefore, we conclude that Kiera got the right 63 questions.

Formula for the surface area of a cylinder, SA = 2ar2 + 2arh. Solve for h.
MakcuM [25]

Answer:

h=\frac{SA-2\pi r^2}{2\pi r}

Step-by-step explanation:

The formula for the surface area of a cylinder is:

SA=2\pi r^2+2\pi rh

And we want to solve for the height h.

First, subtract 2\pi r^2 from both sides. This yields:

2\pi rh=SA-2\pi r^2

Now, divide both sides by 2\pi r. This yields:

h=\frac{SA-2\pi r^2}{2\pi r}

And we're done!

To find slope subtract the two points in the coordinate (y). We have 8 and 4 so subtract those two. You get 8-4=4. Now start from the same coordinate expect this time subtract (x). Which is 9-3=6. You have 4/6 simplify and you get 2/3. Your slope is 2/3. Hope this helps
