Since the line is going from the top left to the bottom right, the slope is negative so A and B are possible answers.
the line crosses the y axis at -1
B is the option that ends with -1
therefore your answer is B. y = -2x - 1

360° ÷ 10 ÷ 2 = 18°
So the length of the decagon side is:
10 × tan18° × 2 = 20 × tan18°
The area is: ½ × 20 × tan18° × 10 × 10 = 1000 × tan18°
≈ 324.9
.: <u>3</u><u>2</u><u>4</u><u>.</u><u>9</u> is the final answer.

-2 1/7 is the correct answer.
If the surface area of the cylinder is 12π square meters. Then the radius of the sphere will be 1.7 meters.
<h3>What is a cylinder?</h3>
A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.
A cylinder has a height of 4 meters and a radius of 1.5 meters.
Then the approximate radius of a sphere that has the same surface area as the cylinder.
We know that the Surface area of the cylinder will be is given as
Surface area = 2πrh
Surface area = 2 x π x 1.5 x 4
Surface area = 12π square meters
Then we have
Surface area of sphere = surface area of cylinder
4πr² = 12π
r² = 3
r = 1.7 meters

#SPJ1
given:
she had: $35.13
+ her mom gave her: $7.50
+ she was paid $10.35
- add all of these up for total.
35.13 + 7.50 + 10.35
= $52.98
<em>look back at the answer i posted before for explanations. the answer for this would be 4/14, which is simplified to 2/7.</em>
