Suppose one of your friends was absent from school on the day your math class learned about graphing rational numbers on the number line. Using complete sentences, explain to your friend how to graph the opposite of 6.2 on the number line.

Answers

Answer:

So i would ask this friend to draw a number line and label 6.2 on the number line. Then i would ask her if she knew what the opposite number of 6.2 is.

Yes- The number line will always continue, its indefinite. This means it can go forward or backwards. Make sure that your friend wrote 0. You always need a starting point. Then tell her to draw the tally marks forward the same way she did backwards. Locate the 6.2 and make all of the numbers negative.

One shirt is represented as “y”

He ordered four shirts totaling $44

y+y+y+y =$44

Answer:

1. x = 462.30m

2. c

Step-by-step explanation:

1. Let "x" represent how much Samantha earns, and "m" represent how many months she has worked.

Because she makes $462.30 per month, if we multiply that by "m" then we will get x.

2. Kyle spend $44 on four sweaters total, which would make the total cost be evenly distributed into 4 sections.

Need help ASAP please--about estimate. which answer is correct. Please give me an opinion. Three students were asked to use estimation strategies to find a reasonable solution to this question: Ricky had 26 stickers before buying 7 from the store. Then he gave 8 to his sister. Estimate how many stickers he has left. From the choices below, select the student with the most reasonable solution.
a) Student A: Ricky has around 45 stickers left. Round 26 stickers to 40, 7 bought to 10, and 8 given to 5. Add 40 + 10 to get 50. Then subtract 50 − 5 to get the estimated answer of 45.
b) Student B: Ricky has around 30 stickers left. Estimate the sum of 6 from the 26 stickers plus 7 bought to be about 20. Add the 20 to the leftover 20 to get 40. Round 8 given to 10. Then subtract 40 − 10 to get the estimated answer of 30.
c) Student C: Ricky has around 10 stickers left. Estimate the sum of 6 from the 26 stickers plus 7 bought to be about 10. Add the 10 to the leftover 10 to get 20. Round 8 given to 10. Then subtract 20 − 10 to get the estimated answer of 10.

Step-by-step explanation:

First I set up a formula to solve how many ounces of salt there were out of 30,      

x/30=20/100, I crossed multiplied and got 5/30, next, I set up the same formula for how many ounces of salt there were out of 25, x/25=30/100, I got 7.5, the last thing I did was add them both together leading me to the answer 12.5 or 12 1/2. Hope this helps! Please say if I am wrong.

The inverse of the function is h ( x ) = (1/2)x - 1/2

What is a function rule?

The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = 2x + 1

The inverse of the function is calculated by taking the x coordinate and replacing it with y

So , the function now becomes

x = 2y + 1

On simplifying , we get

Subtracting 1 on both sides , we get

2y = x - 1

Divide by 2 on both sides , we get

y = ( x - 1 ) / 2

Now , replacing y with x , we get

h ( x ) = ( x - 1 ) / 2

h ( x ) = ( 1/2 )x - ( 1/2 )

Hence , the inverse of the function is h ( x ) = ( x - 1 ) / 2

If there are 150 people born in the world every minute; how
many are born every Hour? Day? Year?

Answers

Step-by-step explanation:

150 x 60 = 9,000 every hour

9000 x 24 = 216,000 every day

216000x 365 = 78,840,000 every year

Answer:

Hour: 9,000 people

Day: 216,000 people

Year: 78,840,000 people

Step-by-step explanation:

In order to solve this, you need to identify how many minutes there are in an hour, a day, and a year:

Hour: 60 minutes

Day: 60 minutes × 24 hours = 1,440 minutes

Year: 60 minutes × 24 hours × 365 days = 525,600 minutes

Now, you need to multiply each of these numbers by 150 to find how many people are born every hour, day, and year:

Hour: 60 minutes × 150 people = 9,000 people

Day: 1,440 minutes × 150 people = 216,000 people

Year: 525,600 minutes × 150 people = 78,840,000 people

suppose v varies directly as g, and v= 36 when g = 4. find v when g=11​

Answers

Answer:

v = 99 when g = 11

Step-by-step explanation:

Set this up as an equation

36/4 = v/11

Cross multiply

36 × 11 = 4 × v

396 = 4v

Divide both sides by 4 to isolate variable v

396 ÷ 4 = 4v ÷ 4

99 = 1v

99 = v
