Answer:

Look at the image.

Step-by-step explanation:

y = - 3 - 2x

y = - 3 - 2( - 5)

y = - 3 + 10

y = 7

y = - 3 - 2( - 2)

y = - 3 + 4

y = 1

y = - 3 - 2( - 1)

y = - 3 + 2

y = - 1

y = - 3 - 2(2)

y = - 3 - 4

y = - 7

A boogie board that has a regular price of $69 is on sale at a 35% discount. What is the sale price with 7% tax? Please show how you did it no files, no downloading links, nothing

Answers

Answer:

im pretty sure it is 47.99 dollars

Step-by-step explanation:

69x.35=24.15, 69-24.15=44.85, then 44.85x.07=3.1395, 3.1395+44.85=47.9895 but you have to round so it is $47.99

hope this helps :)

Answer:

69 x 35%(0.35) = 24.15.
~~~~~~~~~~~~~~~~~~~~
69 - 24.15 = 44.85
~~~~~~~~~~~~~~~~~~~~
44.85 x 7%(0.07) = 3.14
~~~~~~~~~~~~~~~~~~~~
44.85 + 3.14 = 47.99
~~~~~~~~~~~~~~~~~~~~
Sale price = 47.99

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.)

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).

4. Yes, Zack is correct.

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.

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

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.
