The variables y and x have a proportional relationship, and y = 7 when x = 2.
What is the value of y when x = 5?

Enter your answer as a decimal in the box.

y = ___

Answers

Answer 1

Answer:

17.5

Step-by-step explanation:

x=2

y=7

when y by x, then multiple y by 5.

7/2= 3.5

3.5×5= 17.5

you can also do 7x2 which would give you 14 and then divide 7 by 2 to get 3.5, and add the two together, so 14+3.5=17.

77 PTS!! On the following composite figure, all angles are right angles. All short edges of the figure have a measure of 1.5 centimeters. All long edges have a measure of 3 centimeters. Find the area of the figure. Explain or show how you got your answer.

Answers

Answer:Answer:

 27 cm²

Step-by-step explanation:

There are many ways the figure can be decomposed into parts for which you know the area formula. The total area is the sum of the parts.

__

decomposition

We recognize that each of the tabs is twice as long as wide, so is half a square. The 4 tabs together make 2 squares that are 3×3 cm. Of course, what remains after removing the tabs is a 3×3 cm square in the middle of the figure.

sum of parts

Then the total area is that of 3 squares measuring 3 cm × 3 cm:

 A = s² = (3 cm)² = 9 cm² . . . . . area of one square

 total area = 3A = 3(9 cm²) = 27 cm²

The area of the figure is 27 cm².

The figure can also be considered to be a 6 cm × 6 cm square with four 1.5 cm × 1.5 cm squares removed from its corners. Then the area is ...

 (6 cm)² -4(1.5 cm)² = (36 -4(2.25)) cm² = 27 cm²

This depends on your definition of close.

Rational numbers are numbers that can be written as p/q where p and q are integers and q is not 0. Examples include 22/7 or 1 or 0.5.

Irrational numbers are not rational. Example include pi or square root of 2.

Two rational numbers close to -8 could be -9 and -25/3. Two irrational numbers could be -e and [tex]-5\sqrt{2}[/tex].

Then the order goes -9,-25/3 (since it is -8.333...),[tex]-5\sqrt{2}[/tex] (root 2 is around 1.4 so it is near -7),-e(around -2.7)

Directions: Follow the instructions for the following inequalities.


1. 4 < 7 Multiply both sides by 3, then by 2, then by 4, then by 9


2. 11 > -2 Add 3 to both sides, then add 3, then add (-4)


3. -2 less than or equal to -2 Subtract 6 from both sides, then 8, and then 2


4. -4 < 8 Divide both sides by -4, then by -2


5. Write a short explanation of the effects of the above operations. Did this affect the inequality sign? Was it still true? Why or why not?

Answers

Answer:

1. 504 < 1512

2. 12 > 0

3. -2 = -2

4. -1 < 2

Step-by-step explanation:

Given that both sides are being changed by the same amount and sign, the sign never changes. They always have the same value.
