Answer 1

Part (a)

Answer:  x = 0

-----------------

Work Shown:

[tex]3\left(\frac{x}{7}+2\right) = 6\\\\\frac{x}{7}+2 = \frac{6}{3}\\\\\frac{x}{7}+2 = 2\\\\\frac{x}{7} = 2-2\\\\\frac{x}{7} = 0\\\\x = 7*0\\\\x = 0\\\\[/tex]

In step 2, I divided both sides by 3. In step 4, I subtracted 2 from both sides. In step 6, I multiplied both sides by 7.

================================================

Part (b)

Answer:  x = 3

-----------------

Work Shown:

[tex]2\left(\frac{5x}{3}-1\right) = 8\\\\\frac{5x}{3}-1 = \frac{8}{2}\\\\\frac{5x}{3}-1 = 4\\\\\frac{5x}{3} = 4+1\\\\\frac{5x}{3} = 5\\\\5x = 3*5\\\\5x = 15\\\\x = \frac{15}{5}\\\\x = 3\\\\[/tex]

The steps are fairly similar to part (a). The steps were

divide both sides by 2 (step 2)add 1 to both sides (step 4)multiply both sides by 5 (step 6)divide both sides by 5 (step 8)

line e has a slope of -2/9. line f is perpendicular to e. what is the slope of f

Answers

Answer:

9/2

Step-by-step explanation:

In order to find the slope of a line that is perpendicular to another line, you must find the opposite and reciprocal of that slope. So, you have 2/9, and then 9/2.

Answer:

slope of f = [tex]\frac{9}{2}[/tex]

Step-by-step explanation:

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{2}{9} }[/tex] = [tex]\frac{9}{2}[/tex]

A tree measured 18 1/2 feet tall. Over the next 7 1/2 years, it grew to be 63 1/2 feet tall. During the 7 1/2years, what was the average yearly growth rate of the tree?

Answers

Step-by-step explanation:

first subtract how tall is was 7 1/2 years ago from hell with all it is now. 57 - 40.5 = 16.5 or 16 1/2 so and the seven and a half years the tree Grace 16.5 with 16 1/2 seats to get the average yearly growth for the 7 1/2 year. You have to divide 16 and 1/2 ft by 7 and 1/2 Tim Wiles it makes it much easier if you change the fractions to decimals

Answer:

1. 120

2. 26

3. 145

4. 95

5. 129

6. 98

Step-by-step explanation:

Number 1:

Remember: Diagonals are congruent (in this case scenario).

Remember: Consecutive angles are supplementary.

☆You are going to subtract 60 from 18p. (You are subtracting it from 180 specifically because the angles are on a straight angle, and a straight angle equals 180 degrees.)

[tex]180 - 60 = 120[/tex]

^Hence your answer^

Number 2:

Remember: Consecutive angles are supplementary.

☆You are going to subtract 154 from 180.

[tex]180 - 154 = 26[/tex]

Number 3:

Remember: Consecutive angles are supplementary.

☆You are going to subtract 35 from 180.

[tex]180 - 35 = 145[/tex]

Number 4:

Remember: Consecutive angles are supplementary.

☆You are going to subtract 85 from 180.

[tex]180 - 85 = 95[/tex]

Number 5:

Remember: Consecutive angles are supplementary.

☆You are going to subtract 51 from 180.

[tex]180 - 51 = 129[/tex]

Number 6:

Remember: Consecutive angles are supplementary.

☆You are going to subtract 82 from 180.

[tex]180 - 82 = 98[/tex]

Cassie bought 2 apples for $4. Olivia bought 5 apples for $15. How much more money did Oliva spend per apple? Use the dollar sign!

Answers

Answer:

$1

Step-by-step explanation:

To find out how much more money Olivia spent per apple, we need to find out how much each spent on one apple.

Cassie:

2 apples --- $4

1 apple --- $4 ÷ 2 = $2

Olivia:

5 apples --- $15

1 apple --- $15 ÷ 5 = $3

Difference per apple = $3 - $2

                                   = $1

Which of the following numbers has the same absolute value as 86?
A.-86
B.0
C.-172
D.-43

Answers

Answer:

A. -86

Step-by-step explanation:

The absolute value is the distance a number has from zero.

Two numbers that are the same, except that one is positive and negative, will have the same absolute value.

So, -86 and 86 have the same absolute value of 86. This is because they are both 86 away from 0.

So, A is the correct answer.

Given:

A geometric figure.

To find:

The point of tangency in the given figure.

Solution:

We know that, the point of tangency is a point where the tangent line touches the curve.

From the given figure it is clear that, two lines touch the circle at R and Z.

These two lines are tangent and they touch the curve at points R and Z. So, R and Z are point of tangency.

Therefore, the correct option is C.

You are the president of an interior design company. You pay a part-time designer
$200 per week, plus $25 for each completed design. Write an equation to represent this
situation. Use this equation to determine how many completed designs you can have per
week if your weekly design budget is $800?

Answers

Answer: 24

Step-by-step explanation:

Okay, so if the part-time designer gets 200 dollars per week, we should subtract 200 by 800.

800 - 200 = 600.

Then we divide 600 by 25, and that will be the amount of completed designs we'll be able to have each week.

600 ÷ 25 = 24.

So in conclusion, you can pay the designer $200 per week and get 24 completed designs from him.

Hope this helps!

The answer is 24 !!! Good luck

A construction company is starting to build a new house. They need to put tape around the site to begin. The new home site is 202020 meters wide by 404040 meter long rectangle. The company already has 100100100 meters of tape. How much more tape does the company need to tape the site?

Answers

Answer:

20 meters

Step-by-step explanation:

A construction company is starting to build a new house. They need to put tape around the site to begin. The new home site is 20 meters wide by 40 meter long rectangle. The company already has 100 meters of tape. How much more tape does the company need to tape the site?

We would have to find the perimeter of this rectangle

Perimeter fo a rectangle = 2L + 2W

In the above question,

L = Length = 40 m

W = Width = 20 m

Hence:

Perimeter = 2(40m) + 2(20m)

= 80m + 40m

= 120m

Hence, he would need 120 meters of tape

From the above Question, the company already has 100m

Hence, the amount of tape that the company needs more =

120m - 100m = 20 m

Here as by the given information ,

♦ sinA = Opposite/Hypotenuse

♦ cosA = Adjacent/Hypotenuse

♦ TanA = Opposite/adjacent

So here we need to find the same for angle B so we need to use the same formulas for angle B also .

→ sinB = Opposite/Hypotenuse = 12/13

→ cosB = Adjacent/Hypotenuse = 5/13

→ tanB = Opposite/Adjacent = 12/5
