Answer:
745.44 mm² (nearest hundredth)
Step-by-step explanation:
Section the shape into a semicircle, a rectangle and a triangle by drawing a line vertically through the point, and a vertical line upwards from the corner of the 12.5 mm and 32.5 mm corner.
area of semicircle = (1/2)
r² = 78.125
mm²
area of the rectangle = 12.5 x 25 = 312.5 mm²
area of triangle = 1/2 x (55 - 25) x 12.5 = 187.5 mm²
total area = 312.5 + 78.125
+ 187.5 = 745.44 mm² (nearest hundredth)
Answer:
32 256 cubic inches
18.7 cubic feet
Step-by-step explanation:
4 feet = 4 × 12 = 48 inches
8 feet = 8 × 12 = 96 inches
7 inches = 7 ÷ 12 = 0.583 feet
Volume = length × width × height
V = 48 × 96 × 7 = 32 256 cubic inches
V = 4 × 8 × 0.583 = 18.7 cubic feet
Answer:
Angle is 5
Parallel lines are 3
Perpendicular lines are 2
Plane is 1
Circle is 4
Answer:
78 is 7 divided by 8, which equals 0.875. So an equivalent fraction is another fraction that also equals 0.875.
There are now 10 balls in the bag since you took 1 green out
There are now 3 greens in the bag
3/10 is the chance you pick a green,so 7/10 is the chance you DIDNT pick a green ball for the first round
Second round:-1 ball that is not green now the number of ball is 9
10+9=19
(# of green balls still in the bag)3/19 final answer
