(PLS HELP) The water temp at the beach started at 82 degrees and it's rising 0.6 degrees each hour. if the water temp is now at 85 degrees, write an equation and solve an equation to find H, the number of hour passed.

Answers

0.6H=85 would probably be the answer

the water temperature at the beach started at 82 degrees and it is rising 0.6 degrees each hour
——

If the water temperature is now 85 degrees write and solve an equation to find h, the number of hours that have passed
——

Current water temperature at beach =82°
temperature rising rate degrees per hour =0.6°
——-

let H be the hours passed.
water temperature at the beach after hour H be =82+0.6H

Therefore,
equation for water temperature after H hour is =82+0.6H
when water temperature is 85°
85 =82 +0.6H
0.6H = 85- 82
0.6H =3
H=3/0.6
H=5 hours

therefore it will take 5 hours to reach temperature of 85°

Shane has a piece of rope that is 7 4/5 units long. If he cuts it into pieces that are each 3/5 of a unit long, how many pieces does he have?

Answers

Answer:

13 pieces

Step-by-step explanation:

7 4/5 divided by 3/5 is equal to 13

Number of pieces = (7 4/5) / (3/5) = (39/5) / (3/5) = (39/5) x (5/3) = 13 pieces

The width of a rectangle is 4n - 1.5 feet and the length is 1.5n + 4 feet. Find the perimeter of the rectangle. The perimeter of the rectangle is feet.
(Simplify your answer. Use integers or decinals for any numbers in the expression.)

Answers

Answer:

11n + 5

Step-by-step explanation:

First, what is the perimeter of a rectangle referring to? It's referring to the outside surrounding the rectangle. You just need to know that the formula for a rectangular perimeter is:

2(L+W) (W = width, L = length)

We are given width: 4n - 1.5We are given length: 1.5n + 4

Now substitute those values for the formula.

2 (4n-1.5 + 1.5n + 4)2 (5.5n + 2.5)11n + 5

It's different because the experiment is more accurate as it progresses.

Step-by-step explanation:

You'll notice that the higher the numbers get in the experiment the closer it gets to your solution. The theoretical probability of flipping a coin is about 50% heads and 50% tails, but it doesn't always seem like that in an experiment. The experimental probability from your experimentation so far would be 62% of heads and 38% of tails.
