Answer:
33-9+40-(30+15) =
33-9+40+25-(30+15) =
3+21 x 6-(24-4) =
3+21 x 6-(24-4) x 2 =
(62 ÷ 2 – 3) x 3 +6 =
(62 ÷ 2 – 3) x 3 +6 x 2=
0.3+0.8+0.2=
30+30×0+1=
Step-by-step explanation:
I know what it is. it is (V-7)(V+1)
Answer:
Part of work left to finish after two work hours is 7/20
Step-by-step explanation:
Firstly, we need to calculate their joint work rate
That will be;
1/(1/5 + 1/8) = 1/(13/40) = 40/13
This means that they will complete the task in 40/13 hours
1 whole part takes 40/13
x part will take 2 hours
x * 40/13 = 2
40x = 26
x = 26/40
So the part that will be completed in two hours is 26/40
This means that the part left to complete will be:
1 - 26/40 = 14/40 = 7/20
Answer:
Step-by-step explanation:
a^2 + b^2 = c^2
where
a and b are the legs
and
c is the hypotenuse
.
the problem gives the "legs" because the LONGEST leg is always the hypotenuse.
a^2 + b^2 = c^2
1071^2 + 1840^2 = c^2
1147041 + 3385600 = c^2
4532641 = c^2
