5, 10, 8, 9, 9, 9

TYPE ONLY THE NUMERIC ANSWER (Round to the nearest tenths place)

Answers

Answer 1

Answer:

8.3

Step-by-step explanation:

5+10+8+9+9+9=50

50/6=8.333333333333333333333333333333333333333333

=8.3

Answer 2

Answer:

The mean is basically the average.

In order to find avergae you add up all the given numbers and then divide it by the amount of given numbers.

in this case…

5 + 10 + 8 + 9 + 9 +9 = 50

There are 6 given values, which are 5, 10, 8, 9, 9, 9.

We divide 50 (the total number) by the given amount (6).

50/ 6 = 8.33333…

Your answer is 8.3

The approximate total surface area of Earth is 5.1 × 10^8 km2. All the salt water on Earth has an approximate surface area of 352,000,000 km2, and all the freshwater on Earth has an approximate surface area of 9 × 10^6 km2. How much of Earth's surface is covered by water, including both salt and fresh water? Write your answer in scientific notation.Single line text.

Answers

Answer:

3.61x10^8km^2

Step-by-step explanation:

In this problem, we are expected to solve for the total area covered by water,   by addition of scientific notation

Given data

Area covered by salt water=  352,000,000 km2

Area covered by fresh water= 9 × 10^6 km2=9,000,000

Earth's surface is covered by water= 352,000,000 +9,000,000

Earth's surface is covered by water= 361000000

In scientific notation it is 3.61x10^8km^2

Suppose y varies directly with x. Write a direct variation equation that relates x and y.
y=-10 when x=2

Answers

Answer: Suppose y varies directly with x. Write a direct variation equation that relates x and y.

Step-by-step explanation:

Answer is y = -5x

The equation for y varies directly with x is, y = - 5x.

What are ratio and proportion?

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, y varies directly with x.

Therefore,

y ∝ x.

y = kx, where k is the proportionality constant.

At y = - 10 when x = 2.

- 10 = 2k.

k = - 5.

So, y = - 5x.

A bedroom is 15 ft long and 12 ft wide. How much will it cost to carpet the room if carpeting costs $22 per square yard?

Answers

Answer:

$1,320

Step-by-step explanation:

To find the area of the bedroom, you must multiply the length and the width. 15 multiplied by 12 is 180, so the area of the bedroom is 180 square feet. There are three feet in a yard, so you must divide the area of the bedroom in feet by 3 in order to get the area of the bedroom in yards. 180 divided by 3 is 60, so the area of the bedroom is 60 square yards. In order to find how much it will cost to carpet the room, you must multiply the area of the bedroom in yards by how much carpeting costs per square yard. 60 multiplied by 22 is 1,320, so it will cost $1,320 in order to carpet the room.

========================================================

Explanation:

For any parallelogram, the diagonals cut each other in half. Formally this is known as bisection.

What this means is that the pieces AE and CE are the same length.

AE = CE

6x-8 = 2x+24

6x-2x = 24+8

4x = 32

x = 32/4

x = 8

Then we can calculate the length of each piece mention

AE = 6x-8 = 6*8-8 = 48-8 = 40CE = 2x+24 = 2*8+24 = 16+24 = 40

Both pieces are 40 units long to confirm we have the correct x value.

Therefore,

AC = AE + CE = 40+40 = 80

What is a function?

A function from a set X to a set Y assigns to each element of X exactly one element of Y.

We need to find the value of g(3).

From the question, we have

g(x)= x-1,  -2≤x<-1

g(x)= 2x+3, -1≤x<3

g(x)= 6-x,     x≥3

The value 3 is in the function g(x)=6-x

When x is 3

g(3)=6-3

Subtract 3 from 6.

g(3)=3

Therefore value of function g(3) is 3.
