Answer: 5 hours = 300 Kilometers

Step-by-step explanation: If a car can travel 180 kilometers in three hours then in one and a half hour that car can travel 90 kilometers. If you divide 90 by 3 you will find out that in a half hour that car can travel 30 kilometers. So add 180+90+30=300 that is the same as adding three hours+one and a half+thirty minute=five hours

Hope This Helps!!!!!

Sam is tiling a floor. He will use the same repeating pattern for the entire floor. The rule is "Blue Tile, White Tile, Black Ti
snow_lady [41]

If he uses 85 tiles, 28 tiles will be black

<h3>Sequence and Pattern</h3>

The formation of the tiles of the floor follows an arithmetic sequence or pattern

The pattern is given as:

  • Blue
  • White
  • Black

<h3>Formation of the tiles</h3>

Given that the total number of tile used is 85, and the black tile is always in the third position.

The highest number less than or equal to 85 that is divisible by 3 is 84.

Next, we divide 84 by 4

n = \frac{84}{3}

n = 28

Hence, 28 of the tiles will be black

Doss [256]
Im not an expert or anything, but i think for the innequality, i would say

6.50p + 100 \leqslant 500

as far as the amount of people she can invite, do 500-100=400 because of the setup fee, then, to find how many people she can invite. 400÷6.50 which leaves you with the highest amount of people she can invite without going over budget, as 61.

What is the best result for h?
Kryger [21]

Answer: First option.

Step-by-step explanation:

To solve for "h" from the given the equation S=2\pi rh+2\pi r^2, you need to:

Apply the Subtraction property of equality and subtract 2\pi r^2 to both sides of the equation.

Then you need to apply the Division property of equality and divide both sides of the equation by 2\pi r.

Then:

S-2\pi r^2=2\pi rh+2\pi r^2-2\pi r^2\\\\S-2\pi r^2=2\pi rh\\\\\frac{S}{2\pi r}-\frac{2\pi r^2}{2\pi r}=\frac{2\pi rh}{2\pi r}\\\\\frac{S}{2\pi r}-r=h
