Answer:
15/60.
Step-by-step explanation:
25/100 is 1/4 so a 4th of 60 would be 15. 1/4 = 1/4
Answer:
3700hours
154days
Step-by-step explanation:
Speed can be defined as the distance cover per time, it can be expressed as
Speed= distance/ time........eqn(1)
Given:
distance between two planets= 4.07×10^¹²
speed of light = 1.1×10^⁹ kilometres per hour
Time= ??
Then substitute the values into equation (1) we have
Speed= distance/ time
1.1×10^⁹ kilometres per hour= 4.07×10^¹²kilometre/ time
Cross multiply, we have
Time= (4.07×10^¹²kilometre) /(1.1×10^⁹ kilometres per hour)
Time= 3700hours.
To convert to day, we know that
60 minute= 1hour
24hour=1day
Time= (3700hour×1day)/24hour
Time= 154days approximately.
Hence, the time taken for light to travel from one of these planets to the other is 154days or 3700hours
Answer:
here the answer is 327
Step-by-step explanation:
3x^4y^3 - 15 x^2y^2 +6xy
we can factor out 3xy
3xy(x^3y^2 -5xy+2)
we cannot factor any further
Choice A
Answer: answer is C
Step-by-step explanation:
You got the area of the rectangle right the 12 by 8 it is 96
but you forgot about the triangle on top
Here are the formula's
rectangle: a=lw
triangle: a=hb/2
so the base of the triangle is 12 and the height is 4
12·4=48
48÷2=24
so you have to add 96+24=120
so c is your answer
