7 students have 3 books each. Which helps you find the total number of books?

Answers

Answer:

21 Books in total

Step-by-step explanation:

If you just want the total number of books, here:

If each student has 3 books, and there are 7 students, we can create the equation: 7 * 3 :because this is showing that 7 people each have 3 books

7 * 3 = 21 so There are 21 books in total

Another we could write it is 3 + 3 + 3 + 3 + 3 + 3 + 3 because there are 7 students with 3 books each. Adding this up would equal 21.

Answer:

21 books in total

Step-by-step explanation:

If there is 7 students who have 3 books each, and want to find the total. The easiest way is multiply 7 with 3 to give you an answer of 21

Or draw a picture if it helps

Draw 7 stick figure and under it draw 3 books for them and count the books, still gives you 21

What is the value of y in the equation 5x + 2y = 20, when x = 0.3?

Answers

Answer:

9.25

Step-by-step explanation:

5(0.3) = 1.5

20-1.5=18.5

18.5÷2=9.25

Answer:

y = 9.25

Step-by-step explanation:

5x + 2y = 20

when x = 0.3 we have

5(0.3) + 2y = 20

1.5 + 2y = 20

Using the subtraction property subtract 1.5 from both sides of the equation

That's

1.5 - 1.5 + 2y = 20 - 1.5

2y = 18.5

Divide both sides by 2

[tex] \frac{2y}{2} = \frac{18.5}{2} [/tex]

We have the final answer as

y = 9.25

What is the domain and range in this graph?

Answers

Step-by-step explanation:

The graph starts when the value of x is -1 and ends when it's value is 5 , So domain is [-1,5]

The highest value of the graph is 4 which is at x = -1 and the lowest value of the graph is 0 , which is at x = 5, So range is [0,4]

The domain is equal to all the input values (x-values)

The range is equal to all the output values (y-values)

In this problem,

The domain: [-1, 5]

The range: [0, 4]

Is it true that square roots can be compared and ordered by comparing and ordering the numbers underneath the radical symbol?

Answers

Answer:

Yes

Step-by-step explanation:

I had this same question on a quiz and it is correct!

The square root of a number is equal to another number that when squared is equal to the original number.

Now we want to see if Is it true that square roots can be compared and ordered by comparing and ordering the numbers underneath the radical symbol, and we will see that yes, this is true.

To see that this is true:

For example, if the A and B are two numbers larger than 0, such that:

A > B

Then:

√A > √B

For example let's use A = 9 and B = 4.

9 > 4

And obviously the roots are:

√9 > √4

3 > 2

So yes, we can compare and order square roots by comparing the numbers inside of it.

The telephone company offers two billing plans for local calls. Plan 1 charges ​$32 per month for unlimited calls and Plan 2 charges ​$17 per month plus ​$0.03 per call.

Answers

Answer:

The indifference point is 500 calls.

Step-by-step explanation:

Giving the following information:

Plan 1 charges ​$32 per month for unlimited calls and Plan 2 charges ​$17 per month plus ​$0.03 per call.

I assume we have to determine the indifference point between the two plans.

First, we need to structure the cost formulas:

Plan 1= 32

Plan 2= 17 + 0.03*x

x= call

Now, we need to equal both formulas:

32 = 17 + 0.03x

15= 0.03x

500= x

The indifference point is 500 calls.

Plan 1= $32

Plan 2= 17 + 0.03*500= $32

The diagram tells us 3 things: the right angle and the two corresponding side measurements. Because the side measurements are corresponding, we can set a proportion:

6/9=9/15

If this proportion is true, it means the triangles are similar. If this proportion is impossible, it means the triangles are no similar.

To calculate this, we use cross multiplication.

6/9=9/15

6*15=9*9
90=81

90 does not equal 81 making this proportion impossible, which concludes that these two triangles are not similar.
