Tina has 13 cups of water to divide evenly among 7 plants. which of the following best approximates the number of cups of water that each plant will get ?
1/2, 1, 1 1/2, 2, 2 1/2

Answers

Answer:

Option d, 2 cups.

Step-by-step explanation:

Tina has the number of cups of water = 13

She has to divide evenly among the number of plants = 7

The number of cups of water that each plant will get

= [tex]\frac{13}{7}[/tex] cups

= [tex]1\frac{6}{7}[/tex] cups

= 1.857 ≈ 1.9 cups

among the given 4 option, best approximates the number of cups would be 2 cups.

Option d, 2 cups.

Step-by-step explanation:

P is the number of phones left for Kathy to fix

d is the number of days she worked.

This means every day Kathy works, she fixes 23 phone per day or 23 phones fixed a day. The total amount of phones is 108 which is what she has to fix every week.

The only option that makes sense is:

Pls help me with this question

Answers

Answer:

6 years and 15 years of age

Step-by-step explanation:

Given the ratio of their ages is 2 : 5 = 2x : 5x ( x is a multiplier )

Then in 9 years their ages are 2x + 9 and 5x + 9 in the ratio 5 : 8

By proportion

[tex]\frac{2x+9}{5x+9}[/tex] = [tex]\frac{5}{8}[/tex] ( cross- multiply )

5(5x + 9) = 8(2x + 9) ← distribute parenthesis on both sides

25x + 45 = 16x + 72 ( subtract 16x from both sides )

9x + 45 = 72 ( subtract 45 from both sides )

9x = 27 ( divide both sides by 9 )

x = 3

Thus

Rohit's age = 2x = 2( 3) = 6

James' age = 5x = 5(3) = 15

6 : 15 = 2 : 5

Joshua and Caleb work at a furniture store. Joshua is paid $175 per week plus 5% of his total sales in dollars, x, which can be represented by g(x)=175+0.05x. Caleb is paid $532 per week plus 2% of his total sales in dollars, xx, which can be represented by f(x)=532+0.02x. Determine the value of x, in dollars, that will make their weekly pay the same.

Answers

Answer: x = $11,900

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Joshua’s earnings: g(x)=175+0.05x

Caleb's earnings: f(x)=532+0.02x.

So, if both earnings are equal:

g(x) =f (x)

175+0.05x =532+0.02x

Solving for x:

0.05x-0.02x = 532-175

0.03x= 357

x = 357 /0.03

x = $11,900

Which transformations are rigid transformations? Check all that apply.
dilation
reflection
rotation
stretch
translation

Answers

Answer:

Reflection, rotation and translation

Step-by-step explanation:

By definition, a rigid transformation is a transformation that preserves length.

Dilation and stretch change the measure of the figure, and then, they are not rigid transformations.

On the other hand, reflection, rotation and translation don't change the measure of the figure, only change its position and orientation, so, they are rigid transformations.

Reflection, translation, dilation are rigid transformations.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.

Rigid transformations is a transformation that preserves the shape and size of the figure. Types of rigid transformation are reflection, translation, dilation.

Answers

Hi!

I'm Happy to help you today!

The answer to this question would be 30!

This is because to find the mean you have to add everything up, then divide it by how many number's there are so for this problem it is:

30 + 45 + 25 + 25 + 35 + 5 + 40 + 35 + 40 + 20 = 300

Then Divide!

300 ÷ 10 = 30

So 30 is your answer!

Explain your answer You have been made treasurer for a day at AIMCO, Inc. AEVICO develops technology for video conferencing. A manager of the satellite division has asked you to authorize a capital expenditure in the amount of $10,000. The manager states that this expenditure is necessary to continue a long-running project designed to use satellites to allow video conferencing anywhere on the planet. The manager admits that the satellite concept has been surpassed by recent technological advances in telephony, but he feels that AEVICO should continue the project because $2.5 million has already been spent over the past 15 years on this project. .Although the project has little chance to be viable, the manager be Keves it would be a shame to waste the money and time already spent. Use marginal cost-benefit analysis to make your decision regarding whether you should authorize the $10,000 expenditure to continue the project. Which of the following statements correctly describes your decision? (Select the best answer below.) a) You should not authorize the $10,000 expenditure to continue the project because it is surpassed by new telephony technology. Though the marginal cost-benefit analysis treats the $2.5 million as a cost that is irrelevant to the current decision making, continuing the project would be foolish even if the $10,000 expenditure generates a positive net present value. b) You should not authorize the $10,000 expenditure to continue the project even if the project will generate a positive net present value. The marginal cost-benefit analysis treats the $2.5 million as a cost that is extremely unlikely to be recovered and the $10,000 expenditure will also become a cost unlikely to be recovered. c) You should authorize the $10,000 expenditure to continue the project because the marginal cost-benefit analysis treats the $2.5 million as part of the project's initial capital outlay that can be recovered only if the project is implemented the relationship between frequency and wavelength is:a. directb. inverse c. not related Need helpPleaseeeee Please do only 9, 11, and 13 .
