9. If a person bikes 0.24 miles in 1 minute, how far can they bike in 45 minutes?

10. A test car went 64 miles on 2 gallons in the morning, 16 miles on ½ gallon at noon, and 32 miles on 1 gallon at 5 pm. Is the relationship a proportional relationship?

please answer properly and show or tell me all your work

Answers

Answer:

9. 10.8 miles

10. Yes

Step-by-step explanation:

To solve number 9 I multipled 0.24 x 45 to find the distance the biker can bike in 45 minutes.

Number 10 is yes because the numbers continue proportionaly. If you work it out, you can see that each half gallon takes the car 16 miles. The distances went 16 miles for 1/2 gallon, 32 miles for 1 gallon, would go 48 miles for 1 1/2 gallons, and went 64 miles for 2 gallons.

Describe the square roots of numbers using 2 sentences.

Write one sentence describing the square roots of numbers such as √0.6, which is less than 1.

Write another sentence describing the square roots of numbers such as StartRoot 1.6 EndRoot, which is greater than 1.

Answers

Answer:

Square roots of numbers less than 1 are between 0 and 1, while square roots of numbers greater than 1 are greater than 1. For numbers between 0 and 1, the square root is greater than the number; for numbers larger than 1, the square root is less than the number.

Step-by-step explanation:

The square root of a number less than one is a value that is less than  one. The value of the square root of a number greater than one must also be greater than one.

What is square root?

The square root of a number is the value obtained when the number is raised to the power of 1/2. The symbol of square root in  mathematics is √.

If a number is less that 1. its square root must also be less than 1. Similarly, for the numbers that are greater than one, the square root of the number must also be greater than one.

Answer:

The answer to the question is -1.32

Step-by-step explanation:

The first step will be to write out the equation that we are working with:

This equation is

[tex]0.2b + 0.6a = 12[/tex]

The next step is to write out the values of the figures that we are substituting:

[tex]a = -1.2 b=-3[/tex]

Substitution in mathematics can best be understood as "something being used in place of another thing". This means that wherever the first variable appears in an equation, the substituting values will replace it and multiply the number it is attached to.

In this case, we will replace the 'b' and the 'a' with the - 1.2 and - 3 respectively.

[tex]0.2(-3) + 0.6(-1.2) = -1.32[/tex]
