April and amy have a combination age oh 53.amy is 9 years younger than april. what are april and amy ages.

If the total age of both April and Amy are 53

And Amy is 9 years younger than april.

Then to solve for Amy's age you would subtract 9 from 53 and divide by 2

which equals 22

Since amy is 9 years younger than April, then April's age is Amy's age 22 + 9 which gives you 31

April's age is 31 and Amy's age is 22

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
