Answer:
465 in²
Step-by-step explanation:
square area: A = lw
triangle area: A = 
lw (or base x height)
= (15)(15) = 225
= (8)(15) = 60
There is one square and 4 triangles so...
225 + 4(60) = 465 in²
If this is square So,
area of the shaded region = area of square - area of circle r=1/2 × 7 = 3.5
= (S×S) - (Pi × r^2)
= (7×7) - (3.14 × (3.5)^2 ) = 10.535 cm
The answer would be $112.
explanation:
40%——> .40
280 x .40 = 112
Answer:
15.4 gallons .
Step-by-step explanation:
The rate of gas used = 380/14 = 27.14 gallons per gallon.
So for each gallon used you drive 27.14 miles.
So number of gallons used when travelling 418 miles = 418/27.14
= 15.4 gallons .
Answer:
52 young calves
Step-by-step explanation:
At a dairy farm the ratio of adult milking cows to young calves was 9:2. If there were 234 adult milking cows at the farm, how many young calves were there?
The ration is given as:
adult milking cows to young calves
= 9 : 2
= 234 : x
= 9/2 = 234/x
x = Number of young calves
Cross Multiply
9 × x = 2 × 234
= x = 2 × 234/9
x = 468/9
x = 52
Hence, the number of young calves on the farm is 52.
