Answer:
2x-4+3x+2=48
5x-2=48
5x=48+2
5x=50
x=10
Step-by-step explanation:
this
speed of current is 1.5 mi/hr
Answer:
let the rate in still water be x and rate of the current be y.
speed down the river is:
speed=distance/time
speed=14/2=7 mi/h
speed up the river is:
speed=(14)/(3.5)=4 mi/hr
thus total speed downstream and upstream will be:
x+y=7...i
x-y=4.......ii
adding the above equations i and ii we get:
2x=11
x=5.5 mi/hr
thus
y=5-5.5=1.5 mi/r
thus the speed in still waters is 5.5 mi/hr
speed of current is 1.5 mi/hr
Hey!
------------------------------------------------
Surface Area Formula: 2LW * 2LH * 2WH
------------------------------------------------
2LW:
5 x 1 = 5
5 x 2 = 10
------------------------------------------------
2LH:
4 x 1 = 4
4 x 2 = 8
------------------------------------------------
2WH:
5 x 4 = 20
20 x 2 = 40
------------------------------------------------
Surface Area:
40 + 8 + 10= 58
------------------------------------------------
Answer:
D) 58 cm2
