A company needs to take 10 sample sensor readings. If the sensor collects data at 1/2
of a sample per second, how long will it take the company to take all 10 samples?

Answers

It would take 20 seconds. Because it says 1/2 a sample per second, it would take 2 second to produce 1.

10 (the amount of sensors)
2 (seconds it takes to create a full sensor)

10 x 2 = 20. Therefore, your answer is 20.

How many 1/9's in 31

Answers

There are a total of 279 1/9s in 31.

What is simplification?

Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.

To find out how many 1/9's are in 31, you can divide 31 by 1/9.

This can be simplified by converting the division of a fraction to multiplication with its reciprocal:

31 ÷ (1/9) = 31 × (9/1)

Simplifying the expression on the right side gives:

31 × 9 = 279

So there are 279, 1/9's in 31.

what is 36 divided by 6 equals blank sold 36000 divided by 6 equals ​

Answers

Answer: Quotient of 36 and 6 will be 6. Since, 36/6 = 6 with remainder 0.Therefore, the answer to what divided by 2 equals 36 is 72. You can prove this by taking 72 and dividing it by 2, and you will see that the answer is 36. Tip: For future reference, when you are presented with a problem like "What divided by 2 equals 36?", all you have to do is multiply the two known numbers together.hope this helps have a awesome day/night❤️✨

Step-by-step explanation:

The correct calculations show that 36 divided by 6 equals 6, and 36000 divided by 6 equals 6000.

When we divide 36 by 6, the quotient is 6. Therefore, 36 divided by 6 equals 6.

Similarly, when we divide 36000 by 6, the quotient is 6000. Therefore, 36000 divided by 6 equals 6000.

To calculate these divisions, we divide the dividend (36 and 36000) by the divisor (6) to find the quotient.

In the case of 36 divided by 6, we have 36 ÷ 6 = 6.

For 36000 divided by 6, we have 36000 ÷ 6 = 6000.

Hence, the correct calculations show that 36 divided by 6 equals 6, and 36000 divided by 6 equals 6000.

Can someone please help? f(x) = |x − 2| − 4 and g(x) = 1/2x − 2 solve algebraically for x.

Answers

Answer:

x = 8, x = 0   intercepts: (8,2) (0,-2)

Step-by-step explanation:

|x − 2| is a positive value, x can be x ≥ 2 or x ≤ 2

when x≥2, then

y = x-2-4 =x-6  and y = 1/2x - 2

x-6 = 1/2x-2

1/2x=4

x = 8

When x≤2

y = -(x-2)-4 = -x - 2

y = 1/2x - 2

-x - 2 = 1/2x - 2

x = 0
