Answer: 380 ft^2
Step-by-step explanation:
Length of sides of square=25
Diameter of semicircle=25
Radius=r=25/2=12.5
π=3.14
Area of square=length x length
Area of square=25 x 25=625
Area of semicircle=0.5 x π x r x r
Area of semicircle=0.5 x 3.14 x 12.5 x 12.5
Area of semicircle=245.3125
Area of shaded portion=area of square - area of semicircle
Area of shaded portion=625-245.3125
Area of shaded portion=379.6875
Area of shaded portion=380ft^2

The empirical probability of a 4 or 5 is
(count of outcome = 4 or 5)/(count of all outcomes) = (44 +40)/240 = 7/20
The problem statement asks you to assume the outcomes will remain in this proportion going forward. That is, the number of outcomes (n) of 4 or 5 in the next 60 rolls of the number cube is expected to satisfy
7/20 = n/60
Multiplying that by 60 gives
n = 60*(7/20) = 21
Selection D is appropriate.
(F) 3 8 ·5÷7
Step-by-step explanation:
Number of flour bags=5
Weight per bag of flour =38 lbs
Total amount of flour used =38*5 lbs
Number of loaves of bread made=7
Amount of flour used per loaf of bread = (38*5)÷7

You have to add all of the tiles that he needs painting. 675+300+100=1075. Then to figure out how many paint cans you need, divide 1075 by 450. It equals 2.388... so, you need to round up or else you will be missing some tiles. The final answer is 3 paint cans. Hope this helps
