Answer:
9m^3
Step-by-step explanation:
Seperate the shape to two shapes. Two rectangles.
Volume of the bottom rectangle：3X2X1=6
Volume of the top rectangle：1X1.5X2=3
6+3=9
Answer:
5/51 or 0.098
Step-by-step explanation:
Answer:
B, 6
Step-by-step explanation:
In the equation (x - c)² + (y - d)² = r², (c, d) is the center and r is the radius. In this case, c = -2, d = 7 and r = 6 so the center is (-2, 7) and the radius is 6.
TOTAL NO.OF ANIMALS IN FARMHOUSE=42
RATIO OF COW : BUFFALO=5:9
LET THE NO.OF COWS BE 5X AND BUFFALOES BE 9X
5X + 9X =42
14X=42
X = 42/14
X= 3
TOTAL NO.OF COWS = 5 x 3 =15
TOTAL NO.OF BUFFALOES = 9 x 3 = 27
To answer this item, we let x and y be the rate of the boat in still water and current, respectively. The distance traveled by the object is equal to the product of the speed and the time.
Upstream:
D = (x + y)(6)
24 = 6x + 6y
4 = x + y
Downstream:
D = (x - y)(6)
18 = 6x - 6y
3 = x - y
The values of x and y are 3.5km/h and 0.5 km/h, respectively.
Answers:
Rate in Still water = 3.5 km/h
Rate of the current = 0.5 km/h
