The value is .03.

In order to find the value of any term in scientific notation, use the exponent of the 10 as how many times you have to move the decimal place. Since we have a 2 here, we move it twice. Since the two is negative, we move it to the left (we would move it to the right if it was positive).

3 ---> Move once to the left ---> .3 ------> move again to the left ---> .03

A group of 266 persons consist of men , women and children and there are four times as many men as children and twice as many wo
klasskru [66]

Answer:

see explanation

Step-by-step explanation:

Let c represent the number of children, then

number of men = 4c and number of women = 2c

Sum the numbers of each and equate to 266

4c + 2c + c = 266, that is

7c = 266 ( divide both sides by 7 )

c = 38

Thus

4 × 38 = 152 and 2 × 38 = 76

The group consists of 38 children, 152 men and 76 women

Katen [24]

Answer:

74 weeks

Step-by-step explanation:

Given :

Let x = number of weeks

Gallon A:

Capacity = 666

Leak rate = 4 gallons per week

666 - 4x

Gallon B:

Capacity = 888

Leak rate = 7 gallons per week

888 - 7x

666- 4x = 888 - 7x

666 - 888 = - 7x + 4x

-222 = - 3x

x = 222 / 3

x = 74

After 74 weeks
