378 divided by 3 = 126
So your answer is 126
Answer:
area = 39.25 cm²
Step-by-step explanation:
The top and bottom area of a cheese wedge is shaped like a sector of a circle so finding the area of the top surface of this wedge is same as applying the area of a sector.
Top surface area(sector) = ∅/360 × πr²
where
∅ = central angle
r = radius
Top surface area(sector) = ∅/360 × πr²
area = 45/360 × π × 10²
area = 1/8 × 100π
area = 100π/8
area = 100 × 3.14/8
area = 314
/8
area = 39.25 cm²
33%= 0.33 there are 24 hours in a day 24 x 0.33 or 33% equals 7.92 which rounds to 8 hrs a day
Answer:
no solution
Step-by-step explanation:
There are no values of x that make the equation true.
Percentages are really just fractions out of 100. So 45% is really just 45/100. If you want to find the lowest fractions, you have to break each number up into prime factors and see which overlap. So:
45 = 9x5
= 3 x 3 x 5
100 = 2 x 50
= 2 x 5 x 10
= 2 x 5 x 2 x 5
So 45/100 = 3x3x5/2x2x5x5
Now because there's a 5 on both sides, we can cancel down. If we do, that leaves us with
3x3/2x2x5
Which is 9/20
