120

60

90

Answers

Answer:

180

Step-by-step explanation:

Answer:

The answer is 180

Step-by-step explanation:

To check the answer:

Since 60 is part of a half then 60 * 60 = 120

Now we have to find the other 60 remaining from 180 because 180-120 is 60.

1/2 of 180 is 90.

90-60 = 30

if one half is equal to 90 then the other half is equal to 90.

Which of the following accurately describes either the purpose or benefit, if any, of implementing controls in the design of an experiment? Check all that apply.
Group of answer choices

A. By controlling variables, the differences observed in the response variable can be attributed to the treatment and not some other factor.

B. There is no benefit of control in the experiment.

C. By controlling variables that may influence the response variable, we eliminate variability in the response variable.

D. By controlling variables in the experiment, we eliminate the need to have a control group.

E. By controlling variables that may influence the response variable, we reduce variability in the response variable.

Answers

Answer:

B D OR 2 4

Step-by-step explanation:

The purpose or the benefit for implementing the control in the design of the experiment should be option B and option D.

What is the control in experimental design?

At the time of conducting an experiment, the control refer to an elements where it should not be changed or not be impacted by the other variables.

It is used like the benchmark or the comparsion point where the other test result should be determined.

Moreover, there is no benefit and we remove the requirement of the control group.

Hence, the option b and option d is correct.

Solve. 3(x +4) = 36

Answers

3(x+4)=36

What you need to do is divide both sides of the equation by 3 in the first part

x+4=12

Now you move the constant towards the right side and change the sign

x=12-4

Subtract the numbers to find the answer

x=8, therefore to solve 3(x+4)=36 it will give you x=8 as your answer. Hope this helps ^^

a rectangular park has an area of 2/3 square mile. The length of the park is 2 2/3 the width of the park. What is the width of the park?​

Answers

Answer: Area of the rectangular park = 2/3 square mile

Let us assume the width of the rectangular park = x

Then

The length of the rectangular park = 2 2/3 * x mile

= 8x/3 mile

Then

Area of the rectangular park = Length * Width

2/3 = (8x/3) * x

2/3 = 8x^2/3

(2 * 3)/3 = 8x^2

2 = 8x^2

x^2 = 2/8

x^2 = 1/4

x^2 = (1/2)^2

x = 1/2

So the width of the park is 1/2 feet.

hope this helps have a nice day❤️
