Answers

Answer:$6.84

Step-by-step explanation:

$4.25 + $2.25 = $6.50

5 1/4% in decimal form is 5.25%

6.50 multiplied by 5.25% = $0.34

$6.50 + $0.34 = $6.84

Students in a science class investigated how the speed of sound changes with the air temperature outside. The data are shown in the scatterplot.

Based on the scatterplot, what is the best prediction of the speed of sound when the air temperature is 45°C?

350 m/s

355 m/s

360 m/s

365 m/s

Answers

Answer:360 m/s

Step-by-step explanation:

The best prediction of the speed of sound when the air temperature is 45°C is 360 m/s option third is correct also the graph shows a positive correlation.

What is correlation?

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

As we can see in the graph:

When the air temperature is 10°C the speed of sound is around 337m/s

When the air temperature is 20°C the speed of sound is around 344m/s

When the air temperature is 30°C the speed of sound is around 348m/s

When the air temperature is 40°C the speed of sound is around 355m/s

From the above observation, the air temperature increases the speed of the sound increases.

So when the air temperature reaches 45°C the speed of the sound will be 360 m/s.

Thus, the best prediction of the speed of sound when the air temperature is 45°C is 360 m/s.

the answer would be -1/9

because you're subtracting 8/9 from 7/9, not the other way around.

Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

7/9-8/9=1/9

We have a common denominator

7 -8 is equal to -1  not 1

Stephen says that the numbers 38 and 40 are relatively prime. Explain why he is incorrect in making this statement.

Answers

Answer: 38 and 40 are both even numbers.

even numbers cannot be prime numbers; as they have their own factors.

prime numbers only have two factors: the number 1 and the number itself.

example: 17 is a prime number. the only factors it has is 1 and 17.

38 and 40 are both divisible by 2, so they have more than two factors:

38 = 1 * 38,  2 * 19

40 = 1 * 40, 2 * 20, 4 * 10, 4 * 5

therefore, they are not relatively prime, or prime at all; they are even numbers.

Answer:

they are not because 40 has more that 1 factor it has more than 2 which makes it composite  38 on the other hand is relatively prime it only has 2 factors

A salesperson’s commission rate is 4%. What is the commission from the sale of $39,000 worth of furnaces? Suppose sales would double. What would be true about the commission?

Answers

Answer:

The earnings will double

Step-by-step explanation:

Step one:

given data

we are told that the sales person's earnings is 4% of the sales made.

given that the sales made is $37,000 worth of furnaces.

Step two:

we want to find 4% of $37,000

=4/100*37000

=0.04*37000

=1480

hence for $37,000 the earning will be $1480.

Now suppose sales is doubled that is 37000*2= 74000

we want to find 4% of $74,000

=4/100*74000

=0.04*74000

=2960.

the earnings is $2960.

So if sales doubles the earnings will double

Answer:

Step-by-step explanation:

Its B because you distribute each term inside the parenthesis by the number out side

4×2x= 8x

4×3= 12

Get rid of the parenthesis after distributing

which makes 8x+12

Answer:

B. 8x + 12

Step-by-step explanation:

First you'd start with the parentheses because of PEDMAS. But because you can't do anything in there, you go to multiplying 4 by each item inside the parentheses. 4x2x gives 8x. 4x3 gives 12. Leaving you with 8x+12. Hope that helps! :)
