Answer:
1) Area = 12cm²
2) x = 5cm
Surface area : 69cm²
Step-by-step explanation:
Opposites sides in a rectangle would equal the same.
so Top/bottom = 20+20=40
Front/back = 15+15=30
40+30=70cm²
94-70=24cm² for left and right side 24÷2=12cm²
2) Those lines represents what side it is equal too which also means the same.
3cm, you know that base x height = surface area so surface area ÷ height = base
15/3=5cm
x=5cm
Formula : Base x Height = One surface area
Front/Back= 15+15=30
Top/bottom = 5x3 = 15+15=30
side/side = 3x3=9
30+30+9=69cm²
the answer would be 2 because u divide 8 by 4 and that gives u 2
hope this helps
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
Answer:
