Samantha has a AA battery that is 51mm long. About how many centimeters long is it

Mathematics
1 answer:
Butoxors [25]3 years ago
5 0

Answer:

5.1 cm

. . . . . .

All we have to do is convert our 51mm to centimeters.

We divide the length value by 10 to get our centimeters.

51 divided by 10 = 5.1

All we have to do is move our "invisible decimal"

In my way, every whole number has an invisible decimal at it's end.

For ex: '60.'

We can get into exponents. 10 is 10¹, any exponent is the number of zeros at the end of a number may have. Ex: '10² = 100'

We can move our decimal to the left since we are dividing. The amount of exponent numbers are the amount you move it, multiplying and dividing are different things with that.

Let's get back on topic.

Moving our decimal to the left with dividing is 5.1 since 10¹ has a "1" as it's exponent, making us move it "1" to the left.

Multiplying is going the right way.

I hope this helps.

4. Determine whether the statement is true or false. Prove the statement directly from the definition if it is true, and give a
natta225 [31]

Answer:

The statement is false.

Step-by-step explanation:

Let a and b represent two odd integers.

The average (A) is defined by:

A=\frac{a+b}{2}

In order to prove the statement, you have to show that it's true for all odd integers. But, to disprove it, you just have to find a counterexample where the statement is false.

Notice that it is easier to try to find a counterexample.

For example, a=3 and b=5

A= \frac{3+5}{2} = \frac{8}{2} = 4

The result of the average is even, therefore the statement is false.

The previous calculation is a counterexample.

Fourteen less than three fourths of a number is negative eight. Find the number
Lapatulllka [165]
The word "is" in this kind of problem typically means "=", so we know that something =-8. Since we're finding the number, we should start with the closest thing in the phrase given to that number. In this case, it's 3/4x. Finally, since we have the "14 less than", we need to add that in. Your answer is:

3/4x-14=-8. Now we can just solve!
       +14   +14

3/4x=6.
*4/3   *4/3

x=8.

I'm so so so confused on how to do this. I thought you would have to do a triangle to solve it but it didn't work. HELLLPPPLL!!!
Volgvan
You have to use Pythagoreans theorem. 225=144+x^2
x^2 = 81
sq root of 81 is 9
it is 9 feet away from the wall.
