the parallel sides of a trapezium are such that the longer side is 4cm more than the shorter side of the distance between them i
s 20 cm and the area of trapezium 600 sq cm find the length of the parallel sides
1 answer:
Answer:
32cm and 28cm
Step-by-step explanation:
Area of a trapezium=0.5 ( sum of parallel sides ) × height
600=0.5( 4+a+a)×20
where a is the length of the shorter side
600÷0.5=(4+2a)×20
1200=(4+2a)×20
1200÷20=4+2a
60=4+2a
60-4=2a
56=2a
56÷2=a
28=a.
since the longer side is 4 cm more than th shorter side , 28 +4=32

Step-by-step explanation:
∵∛x = (x)^1/3
∴
So you can replace the radicals by fractional exponents
Answer:
Answer:
slope=1
Step-by-step explanation:
Formula for slope is m =
y2 - y1
/x2 - x1
you will then use 7-8/4-5
Then -1/-1 which will simplify to 1
Answer:
600 volts
Step-by-step explanation:
Given =
A = 12 ampere
V = 480 volts
A2 = 15 ampere
Solution =
R = V/I
= 480 / 12
= 40 ohms
R = V / I
V = R x I
= 40 x 15
= 600 volts
