Craig measured a length as 0.034 millimeters. What is the margin of error? 0.03 mm to 0.04 mm 0.033 mm to 0.034 mm 0.0335 mm to 0.0345 mm 0.0345 mm to 0.0350 mm

Answers

C. 0.0335 mm to 0.0345 mm

Step-by-step explanation:

The least significant digit of Craig's measurement is in the 0.001 mm place. The error in the measurement is presumed to fall within half that value either side of Craig's measurement. So, the actual value is expected to be in the range ...

0.034 - 0.0005 = 0.0335

to

0.034 + 0.0005 = 0.0345

Answers

Given that,

The function is t = f(S).

To find,

The unit of f''(S).

Solution,

The given function shows the time for a sample of water to evaporate as a function of the size S of the sample, measured in millimeters.

f'(S) will be in hours per Mililiter

And

f''(S) will be in hours per Mililiter per Mililiter. Therefore, this is the required solution.

On average, Emma can clean her room in 35 minutes but, depending on how dirty her room is, her time can vary from the average by 20 minutes.

Which absolute value equation can be used to calculate Emma's maximum and minimum time to clean her room?

Let x represent the maximum and minimum time.


|x-20|=35

|x+20|=35

|x+35|=20

|x-35|=20​

Answers

B. |x+20|=35

This is because 20 is the minimum time, so you have to add that to whatever x is. since x can be the minimum or maximum, this further proves this statement. You can also know this is correct because the final product (35) was the maximum time shown in the world problem

2x+8y=56 on a 10x 10 grid

Answers

Answer:

Step-by-step explanation:

Simplifying

2x + -8y = 56

Solving

2x + -8y = 56

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '8y' to each side of the equation.

2x + -8y + 8y = 56 + 8y

Combine like terms: -8y + 8y = 0

2x + 0 = 56 + 8y

2x = 56 + 8y

Divide each side by '2'.

x = 28 + 4y

Simplifying

x = 28 + 4y
