Answer:
10.22 she save
Step-by-step explanation:
18 3/4 x 2.80=51.1
51.1 x 20%=10.22
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.
15h^2 +10h +25 /5h = x +y +
15h^2 +10h +25/5h = 3h +2
15h^2
---------
0 10h
10h
------
0 25
so x=3h and y =2 than the 3rd choice is correct ,right sure
