Answer:
0.105
0.11 if you are expected to round to nearest cent.
Step-by-step explanation:
"of" should be thought of as times.
So you are doing:
7% is the same as .07; you could just replace percent with times 1/100 if you don't know. Like this 7%=7*1/100=7/100=.07.
When putting this into the calculator you get 0.105.
Answer:
4
Step-by-step explanation:
2/3 of 60 is 20 and 1/5 of 20 is 4
Answer:
length = 9 in ; width = 4 in
Step-by-step explanation:
1) formula of the area of a rectangle
A = base x width
2) write an equation with the given informations:
w x (3w-3) = 36
3) solve the equation
- multiply W by 3w and -3
3w^2 -3w = 36
- divide the two members by 3
w^2 - w = 12
- add up -12 at the two members
w^2-w -12 = 12 -12
w^2 - w - 12 = 0
- find two numbers whose sum is -1 and whose product is -12 and factorise the equation
(w-4)(w+3) = 0
- find the two solutions
w-4 = 0
w = 4
w+3 = 0
w = -3
4)remember that a length can’t be negative.
w = 4 is the only solution
5) find the length
4x3 - 3 = 9
Answer:
Step-by-step explanation:
Because the speed has formula of distance divide time = m/s
and the acceleration is speed /time so (m/s)/s = m/(s*s) = m/s^2
hope this is understandably sure easy for you
