How can you write and evaluate numbers with exponents?

Answers

Answer:

an exponent is the small number written above and to the right of a number

on a keyboard it is written like (^) that

ex. If you were saying 2 to the power of 2, you would write it as 2^2

when you see that number, that number is telling you how many times you multiply that number by itself, ex. 2^2 is telling you to multiply 2 by itself

A carpet measures 7 meters 3 decimeters in length and 4 meters 2 decimeters in width. What is its area in square meters?

Answers

Answer:

Step-by-step explanation:

change decimetres into metres

length - 7.3m

Width - 4.2m

to find an area, do length times width

7.3 x 4.2 = 30.66 square metres

I hope this helped :)

Answer:

C. 30.66 square meters

Step-by-step explanation:

The equation for area is A = L × W

L = length

W = width

Because a demimeter is 1 tenth of a meter your new measurements are 7.3 and 4.2.

multiply the measurements to find the area of 30.66² meters

Answer: The number is 8

Please mark brainliest

Step-by-step explanation:

8 is the value of the unknown number 'x' from the equation 5x + 7 =47.

What is linear equation?

" Linear equation is defined as the algebraic expression which has highest power of the given variable equals to one."

According to the question,

'x' represents the unknown number.

As per the condition given linear equation we get,

5x + 7 = 47

Add (-7) both the sides

5x + 7 + (-7) = 47 + (-7)

⇒5x = 40

Divide by 5 both the sides we get,

(5x) / 5 = 40 / 5

⇒ x = 8

Hence, 8 is the value of the unknown number 'x' from the equation 5x + 7 =47.

Answers

x + 4 - 3 = 1

x + 1 = 1

x = 0

Answer:

x = 8

Step-by-step explanation:

√x + 4 - 3 = 1

1) Move constant terms to the opposite side of the equation: √x + 4 = 1 + 3

2) Simplify the right side: √x + 4 = 4

3) Now square both sides to eliminate the square root: (√x + 4)^2 = 4^2 (x + 4) = 16

4) Move the constant term to the other side: x + 4 = 16 – 4

5) Simplify the right side: x + 4 = 12

6) Move constant side to the other side: x = 12 – 4

7) Finally, after simplifying the right side again, you get: x = 8

Therefore, the solution to the equation √(x + 4) - 3 = 1 is x = 8.

Find the measure of angle x in the figure.

Answers

Answer:

Step-by-step explanation:

We know that angles in a triangle add up to 180, so:

5x-60+2x+40+3x-80=180

Simplify

10x-100=180

Solve

Subtract 100 from both sides

10x=80

Divide 80 by 10 to find x

x=8

find the measure of each angle indicated.

The speed of sound is approximately 720 miles per hour at sea level. At this rate, how many feet does it travel in 20 seconds? Use 1 mile=5280 feet.

Answers

Answer: 21120 feet.

Step-by-step explanation: We start with the fraction 1/180, found by putting 20 seconds over one hour. Then, we need to get the amount of miles the speed of sound travels in 20 seconds. We can use the fraction above as a ratio to get it. 720/1 x 1/180 = 4 miles. Then, we'll just do 4 times 5280, which is 21120.

The distance travelled by sound in 20 seconds is 21120 feet.

What is speed?

In unit time the distance covered by any object is called speed.

In mathematical term, Speed is express as S=D/T,

where S=speed, D=distance, T= time.

Given that,

The speed of sound = 720 miles per hour.

According to given condition,

1 hour = 720 miles

Since, 1 hour = 60 minutes

60 minutes = 720 miles

1 minute = 12 miles.

1 minute = 60 seconds

60 second = 12 miles

1 second = 12 / 60 = 1/5 miles

20 second = 20 / 5 = 4 miles

According to given condition,

1 mile = 5280 feet

Therefore,

20 second = 5280 x 4 = 21120 feet

The distance travelled in 20 seconds is 21120 feet.

First we need to find how far away the base of the ladder is from what it is leaning against. The ramp is the hypotenuse and the height from the ground in a leg. Let’s use Pythagorean’s theorem.

a^2 + b^2 = c^2

Substitute

a^2 + (5)^2 = (20)^2

Solve for a^2

a^2 = (20)^2 - (5)^2

Solve for a

POINTS AND BRAINLIEST!Surface Water Lab ReportIntroductionUsing models is very important in science. In this lab, you will design a model that will help you investigate the relationship between land surfaces and water on Earth. Problem: How can we use the relationships between land surfaces and water to understand conservation of resources and pollution?Hypothesis: After completing steps 1 through 5 in your procedures, predict the number and locations of watersheds that will form in your watershed model. For example:Based on the positions of landscape features in my watershed model, I predict there will be ________ number of watersheds located at these locations in my model: __________________________________.Materials: If you would like to create your watershed model by hand, you will need the materials listed. Note: There are alternative procedures that do not require these materials.one sheet of plain white paperseveral sheets of old newspaper, or wax paper if availableone water-based marker (Note: do not use permanent marker)one spray bottle containing water (place on mist setting)digital camera, if availableProcedures:Place several sheets of newspaper or wax paper over a large flat surface, such as a kitchen counter. Use at least five sheets of paper so that you can protect your work area. Crumple the sheet of white paper into a loose wad.Uncrumple the sheet of paper so you can lay it on your work surface. The paper should not be flat but should be wrinkled and puffed up from the crumpling.Imagine the paper as a miniaturized version of mountains, hills, valleys, and other landscape features. If your paper is so flat that you can't imagine these features, you should recrumple it.Use the marker to color the major folds or ridges in the paper, as well as some of the minor folds or ridges. Do not allow the marker to color any other part of the paper.Place the paper on top of the newspaper on the counter, and then lightly mist the piece of paper with the spray bottle. Don't spray too heavily: Three to seven squirts will probably do the job.Stop misting as soon as you see some of the colored water starting to collect in some of the valleys. Watch for a few moments as stream patterns develop over the paper.If you have access to a digital camera, take a photograph of your work and include it in your Data and Observations.Record your observations of each watershed that forms in Table 1.
