You would round it to 656.70 because the 9 behind the 6 is greater than 5 so it rounds up and makes 6 and 7 and all the numbers behind 6 zero.

Answer:

Hence, the required number is 656.7

Step-by-step explanation:

Consider the provided number.

656.692169912

We need to round the number to the 1 decimal place.

There are 9 digits after the decimal place.

First understand the means of rounding to the 1 decimal place.

The meaning of rounding to the 1 decimal place is Round the number value after the integer number, restricted to one decimal place.

For example: Consider the number 8.14 is rounded to 8.1

The rule of rounding a number is:

If 0, 1, 2, 3, or 4 follow the number, round it down.

If 5, 6, 7, 8, or 9 follow the number, round it up.

Now consider the number 656.692169912

The number at 2 decimal place was 9, so to round the 1 decimal place round the number up.

Thus round the number 656.692169912 to the 1 decimal place is:

656.7

Hence, the required number is 656.7

Given the following triangle, what is the measure of the missing side?

Karolina [17]

It's a half of an equilateral triangle because their angles measure 30° and 60° (an equilateral triangle has 3 angles of 60°)
So x=(2h/√3)/2=h√3=27√3≈15.6

Answer:

The radius is 5 cm

Step-by-step explanation:

The formula for the area of a circle is : $\p*radius^2$

To work out the length of the radius you would first need to divide the area of 78.5 cm by pi (pi=3.14), this gives you $25cm^2\\$ . This is because by dividing the area by pi we are isolating the value of the radius squared.

The final step is to work out the radius. You can do this by finding the square root of the radius squared which is 25, this gives you 5 cm. This means that the radius is 5 cm. This is because the square root is a number that when squared equals that number.

1) Divide 78.5 by pi.

$78.5/\pi=25cm^2$

2) Find the square root of 25 cm squared.

$\sqrt{25} =5 cm$

In this question pi is 3.14

Mandy has six boxes of pencils each box contains 10 to the fifth power of pencils how many pencils does Mandy have

Nonamiya [84]

You have to do 10•10•10•10•10 (multiply 10, 5 times). Once you multiply 10 five times, you end up with an answer of 100,000 pencils in each box. Then since you have 6 boxes of pencils you have to multiply 100,000•6, which equals 600,000 pencils total.
