Answer:
12
Step-by-step explanation:
To determine the number of discs, divide the area of the metal sheet by the area of the discs
The metal sheets are in the shape of a rectangle, thus the area of a rectangle would be used to determine the area of the sheet
Area of a rectangle = length x breadth
56 x 33 = 1848 cm^2
The disc is in the shape of a circle.
area of a circle = πr²
π = 3.14
r = radius
3.14 x 7² = 153.86 cm²
Number of discs = 1848 /153.86 = 12
Answer:
131
Step-by-step explanation:
Finding the greatest common factor ( or G C F ):
G C F is the largest number that divides evenly into all the numbers.
270 : 90 = 3
360 : 90 = 4
G C F ( 270, 360 ) = 90
Answer:
1/15
Step-by-step explanation:
7+3 = 10 items in the bag
P(grape) = grapes/total
3/10
No replacement
7 cherries 2 grapes = 9 items
P(grape) = grapes/total
2/9
P(grape, no replacement, grape) = 3/10*2/9
=1/15
