EMERGENCY!!!! Each hour, every person who knows a rumor tells two other people. If one person starts the rumor, then after the first hour, three people know the rumor. The next hour, those three people each tell two more people. After eight hours, how many people will know the rumor? You do not have to include units in your answer. (I've asked this question before but the answers I got were 384 and 64 and they were both wrong)

Answer 1

Answer:

After eight hours 6,561 people will know the rumor.

Step-by-step explanation:

Since each hour, every person who knows a rumor tells two other people, so that if one person starts the rumor, then after the first hour, three people know the rumor, and the next hour, those three people each tell two more people, to determine after eight hours, how many people will know the rumor, the following calculation must be performed:

Hour 0 = 1

Hour 1 = 1 + 2 = 3

Hour 2 = 3 + 2 x 3 = 9

Hour 3 = 9 + 2 x 9 = 27

Hour 4 = 27 + 2 x 27 = 81

Hour 5 = 81 + 2 x 81 = 243

Hour 6 = 243 + 2 x 243 = 729

Hour 7 = 729 + 2 x 729 = 2,187

Hour 8 = 2,187 + 2 x 2,187 = 6,561

Therefore, after eight hours 6,561 people will know the rumor.

Lindsey made a map of her town which place in Lindsey's town is located at 4,5

Answers

Answer:

the school

Step-by-step explanation:

the point given is (4,5) so let's try to hone in on that so to speak-

with that in mind, the way that i find the easiest to answer this is by using rise over run or the crawl before you walk method

seeing as how both are practically the same i'll just go with the craw before you walk method-

so we will 'crawl' to 4 along the x axis then we'll 'walk' and stop once we reach (4,5) and at (4,5) there is the school building and since her town is also located at the same point the school building is the correct answer

good luck :)

Jacob has a rectangular garden with an area of 56 square feet.The length of the garden is 8 feet.What is the width if the garden?

Answers

Answer:

The width of the garden is 7 feet.

Step-by-step explanation:

If the area is 56 feet, and the length is 8 feet, we can put this into the area equation.

Area = width * length

A = wl

Substitute variables.

56 = 8w

Divide by 8.

7 = w, or w = 7.

The width of the garden is 7 feet.

HELP NEEDED!!! 20 POINTS FOR A ANSWER AND EXPLANATION ON QUESTION #2! I cant figure this out help me please

Answers

Step-by-step explanation:

Start at the orgin.

The y intercept in the equation is -1 so I would shift 1 unit down to the orgin at (0,-1)

Then at the point, since the slope is -4. I would go down -4 units then go over 1 unit to the right.. So the next point would be (1,-5) then so on and so on.

You can check if your graph is correct by writing out specific points on the linear equation and making sure there slope is equal to -4.

The height of the right circular cylinder shown below is 10 feet and its base has a radius of 4 feet. A. B. C. D.

Answers

Answer:

502.4ft^3

Step-by-step explanation:

Given data

Height= 10ft

radius= 4 ft

Hence the volume for the cylinder can be gotten as

v= πr^2h

v= 3.14*4^2*10

v=3.14*16*10

v=502.4ft^3

Therefore the volume of the cylinder is 502.4ft^3
