Answer:

C = -13.78

Step-by-step explanation:

Answer:

c = -13.78

Step-by-step explanation:

21.2x + c =5.3(4x - 2.6)

Use distributive property: a*(b + c) = (a*b) + (a * c)

21.2x + c = 5.3*4x - 5.3*2.6

21.2x + c = 21.2x - 13.78

Now to find the value of c, isolate 'c'. So, subtract 21.2x form both sides

21.2x + c - 21.2x = 21.2x - 13.78 - 21.2x

c = -13.78

Answer:

x= 35°

I hope it's helps you

Answer:

The answer is most likely 35

Step-by-step explanation:

This is a right triangle which is equal to 90 degrees and so you do the opposite of what it took to get the sum 90....which is subtract so you subtract 90 from 55 and end up with 35...In order to check your answer you must add 55+35 which of course equals 90....

A shape has rotational symmetry when it looks the same after being rotated less than one full turn. Provide two examples of figures with rotational symmetry.

Answers

Explanation If a figure is rotated around a centre point and it still appears exactly as it did before the rotation, it is said to have rotational symmetry.

Examples : A number of shapes like squares, circles, regular hexagon, etc. have rotational symmetry.

Answer:

12 inches

Step-by-step explanation:

Set up an equation:

Variable x = height of the scale model

3/18 = x/72

Cross multiply:

3 × 72 = 18 × x

216 = 18x

Divide both sides by 18:

The two dot plots below show the heights of some sixth graders and some seventh graders:

Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark. For the bottom line, there is 1 dot for the first mark, there is 1 dot above the second mark, there is 1 dot above the third mark, there is 1 dot above the fourth mark and there are two dots above the sixth mark.

The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 1.7. Approximately how many times the variability in the heights of the sixth graders is the variability in the heights of the seventh graders? (Round all values to the tenths place.)

If you have any questions, on what something says, just ask :-)

Answers

4. Yes, Zack is correct.

56 7

----- = -------

400 50

Think about it. If we multiply both the numerator and the denominator of the second fraction above by 8, we get the same fraction as the one on the left.

7 x 8 56

---------- = -------------

50 x 8 400

∴ Yes, Zack is correct.

We must assume that out of 400 of 150, 000 , about 3 coins will have misprint.

So, we can solve now.

150 000 400 ↔ Think, number of coins divided by misprints.

------------- = -----------

x 3

This is called the rule of three.

(150 000 x 3) = 400

450 000 400x

------------- = ------------

400 400

1,125 = x

∴ We can predict that there will be 1, 125 misprints in a year.

A long-distance runner jogs at a constant speed of 7 miles per hour for 45 minutes. Which spreadsheet formula would give the distance she traveled?
Group of answer choices

A.) =7*45

B.)=7/45

C.)=7*(3/4)

D.)=7/(3/4)

Answers

B: 7/45 explanation: with slope you divide

The spreadsheet formula would give the distance runner traveled is =7*(3/4). The correct option is C.

What is speed?

The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.

Speed = Distance Covered / Time taken

Given that a long-distance runner jogs at a constant speed of 7 miles per hour for 45 minutes. Therefore, we can write the time and speed as,

Time = 45 minutes = 45/60 hour = 3/4 hour

Speed = 7 miles per hour

Now, the distance that the runner will cover can be written as,

Distance = Speed ×Time

Therefore, on the spreadsheet we can write,

Distance = speed * Time

= 7 * (3/4)

Hence, the spreadsheet formula would give the distance runner traveled is =7*(3/4).
