382.5 because just multiply 8.50 times 45 hours
Together it would take 3 hours.
Team A can wrap all gifts in 7 hours; thus they can wrap 1/7 of the gifts in 1 hour.
Team B can wrap all gifts in 5 hours; thus they can wrap 1/5 of the gifts in 1 hour.
1/7h + 1/5h = 1, where h is the number of hours; it equals 1 because it is 100% of the gifts;
Find a common denominator. 35 is the first thing 7 and 5 will both divide into. Convert the fractions:
5/35h + 7/35h = 1
12/35h = 1
Divide both sides by 12/35:
12/35h ÷ 12/35 = 1 ÷ 12/35
h = 1/1 ÷ 12/35
h = 1/1 × 35/12
h = 35/12
h = 2.9
h ≈ 3
Answer:
x = 3
Step-by-step explanation:
49 - 19 = 30
-2x - 12x = 10x
30 / 10 = 3
Question:
Which is equivalent to 
after it has been simplified completely?
Answer:
Step-by-step explanation:
Given
Required
Simplify
We start by splitting the square root
Replace 180 with 36 * 5
Further split the square roots
Replace power of x; 11 with 10 + 1
From laws of indices; 
So, we have
Further split the square roots
From laws of indices; 
So, we have
Rearrange Expression
From laws of indices; 
So, we have
<em>The expression can no longer be simplified</em>
Hence, is equivalent to 
(5x10^4)+(3x10^3)+(8x10^2)+(0x10^1)+6x10^0)
