An inequality is shown below.
-7x > 63

Which inequality represents the solution set?

a. x > 9
b. x > 70
c. x < –9
d. x < –70

Answers

Answer 1

Answer: The answer is d

Step-by-step explanation: This is because a, would have the answer as -63 b would make the answer be -490, and c would have below 63 because -7 x -9 = 63 but if x is below -9 then it would be to low. Lastly for D since a negative times a negative is a positive then you can ignore the negative symbols and just substitute x for 70 and -7 for 7 then multiply. 7 x 70 = 490 which matches the inequality because it is more than 63.

Hope this helps.

The table shows the monthly rainfall at a measuring station. What is the mean monthly rainfall? Round your answer to the nearest thousandth.

The mean monthly rainfall is ___inches.

Answers

Answer:

The mean monthly rainfall is 3.245 inches.

Step-by-step explanation:

The first step in answering this question is to add all of the months together. This gives us; 38.94.

The second step is to divide the added months by 12 because there are 12 months, and 12 numbers that we added together.

This gives us 3.245.

So, the answer is going to be The mean monthly rainfall is 3.245 inches.

Have a good day and good luck!

The mean monthly rainfall is 3.245 inches.

What is Mean?

Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.

Given is a table which shows the monthly rainfall at a measuring station.

Mean of a set of data = Sum of the data vales / Total number of values.

Here,

Total number of data points = 12

Sum of the data points = 2.22 + 1.51 + 1.86 + 2.06 + 3.48 + 4.57 + 3.27 + 5.40 + 5.45 + 4.34 + 2.64 + 2.14

= 38.94

Mean = 38.94 / 12 = 3.245 inches

Hence the mean monthly rainfall is 3.245 inches.

geometry I need help

Answers

Answer:

145

Step-by-step explanation:

Angle 4 and 5 are the same.

Which means that angle 3 and 6 are the same.

A straight line has an angle of 180 degrees in total.

This means that we have to subtract 35 from 180.

This gives us 145.

So, the missing angle is going to be 145 degrees.

*also, 1, 4, 5, and 8 are the same angle.

**2, 3, 6, 7 are also the same angle.

***I just remember learning about this last year, don't remember what there called tho.

Answer:145

Step-by-step explanation:

look at angle 4 and do 180-35 which is 145 and it has the same degree with angle 6

Answers

Answer: C. The housecats' weights have a higher mean and are more consistently centered around their mean.

Step-by-step explanation:

if we were being more technical then he would be correct because the house cats have a higher mean than the smaller dogs.

SD= 9.9

HC= 11

so the house cats have a higher mean than the smaller cats, in addition has a more consistent mean then smaller dogs due to the range of the lowest in the highest number.

Sorry I couldn't help you with there other ones.

Sponsors:

5s + 10 = 200

You need to get rid of 10 first, you do this by subtracting it by 10, you also subtract 10 to 200

5s = 190

Now you need to get rid of 5 that is attached to the variable, you must divide 5 since it is multiplying, also dividing 5 to 190

s = 38

So it would be 38 sponsors



Comic books:

4c + 6 ≤ 20

Take away 6 by subtracting, also subtracting 6 to 20

4c ≤ 14

You then have to divide 4 to the variable, also dividing 4 to 14

c ≤ 3.5

Now since you can’t get half of a comic book, the greatest amount of comic books he can buy is 3.

3 comic books



Value of x:

3x + 1 = 10

Take away 1 by subtracting 1, also subtracting 1 to 10

3x = 9

Divide 3 to the variable, dividing 3 to 9 as well

x = 3



Value of y:

4y + 6 ≥ 18

Subtract 6 to 6 and 18

4y ≥ 12

Divide 4 to both sides

y ≥ 3 or y is greater than or equal to 3 (in case you can’t see the symbol)

A cookie costs $4/7

Step-by-step explanation:

Let's write an eqution in which X represents the cost of a cookie

14x=8

Now divide both sides by 14

[tex]x=\frac{8}{14}[/tex]

Now simplify by 2

[tex]x=\frac{4}{7}[/tex]

So a cookie costs $4/7
