Question
Combine like terms to simplify the expression: -5.55 - 8.55c + 4.35c
Answer:
Step-by-step explanation:
Given: -5.55 - 8.55c + 4.35c
Required: Simplify
We start by performing arithmetic operation on like terms
-5.55 - 8.55c + 4.35c becomes
-5.55 + 4.20c
Then we simplify further by converting decimals to fraction

Rearrange
Hence, the expression -5.55 - 8.55c + 4.35c is equivalent to
Answer:
97.43cm³
Step-by-step explanation:
h = 22cm
d = 10cm
r = d/2
= 10/2
= 5
dh = 2(0.4)
= 0.8
dr = 0.05
V = πr²h
dV = d(πr²h)
Such that
πd(r²h)
= π[(r²dh + hd(r²)]
dV = π[(r²dh + 2rhdr]------(1)
When we put the values above in this equation 1 above:
dV = π[(5)²*0.8 + 2*5*22*0.05]
= π(25*0.8+11)
= π31cm³
Multiply the value of pi with 31cm³
= 97.43cm³
X=4 and x=-4 Your answer would be C.
To solve this problem we must find 5% of 1418 and 4% of 1418
which is
so that would be 70.9 house extra in the first year and 56.72 extra in the second year respectively.
so to find the total number of houses we must add 70.9 + 56.72 + 1418 which gives us 1545.62
at the last it is mentioned for us to round our answer to the nearest
they are asking us for the total number whole number
which is 1546
so there would be 1546 houses in the second year.
