Answer:

30

Step-by-step explanation:

First of all place value and value are two different things. Place value is the position of a number and value is literally the value of a number. So the place value of 731.8 is tens because the order goes units, tens, hundreds etc, but the value is 30 because as said before it is in the tens place value. And as you asking the value of the 3 in 731.8, it is 3x10, which is 30.

The ratio of boys to girl in a school is 5:7 if there are 600 students, how many girls are there
larisa86 [58]

Answer:

350 girls

Step-by-step explanation:

So,

The secret to solving problems with ratios is to find the value of one unit.

5:7 = 12 units total

To find one unit, divide the total number of students by the total number of units.

600/12 = a

Simplify

50/1 = a

50 = a

The value of each unit is 50.

Now, multiply the units by the numbers in the ratio.

50(5) = b

250 = boys

50(7) = x

350 = x

There are 350 girls.

What is the exponential notation for 262,144
7nadin3 [17]

since there is always a decimal at the end of every value so :

           = 262144.0 

        you move the decimal backwards if there is no decimal between the value. you place the decimal after the 1st digit, you will also count the digits you have passed : 

         = 2.62144 X 10^5 

you passed 5 values so you put 5 in exponent form.
