Answer:
the answer is 4 hours.
Step-by-step explanation:
x: time clark drove
Y: Mitchells time drove
60 times Y = 75 times x
y=x+1
60(x+1)=75x
60x+60=75x
60=15x (subtract the 60x to the other side)
60/15=4
x=4
12.67 minutes
Time taken is given by distance divided by speed
Given distance of 228, 000, 000 km and speed of light as 300, 000 km/s then time will be
Time=228, 000, 000/300, 000=760 seconds
Conversion
60 seconds make up 1 minute
760 seconds will be 760/60
Time=760/60=12.666666666666
Rounded off, this is 12.67 minutes
They are perpendicular.
When we convert the equation 6x-2y=-5 into y=mx+b form, it changes into y=3x-5/2. Since we know that perpendicular slopes are opposite reciprocal, the opposite reciprocal of -x/3 is 3. So, we know that these 2 slopes are perpendicular.
idk good luck
thank you
1. diameter=8 kilometres
2. area=98.96 inches
3. 37m
1. diameter= 2*radius
2. area of sector=θ out of 360*π where θ is the angle
3. area of garden=π
706.5=π
=706.5/π
= 225(nearest whole)
r==15m
we now use Pythagoras theorem to find length of each pathway
1600=225+
=1600-225=1375
x==37 m (to nearest whole)
