At 10 am, Car A is at 30 miles.
Then at 11 am, Car A is at 60 miles and Car B is at 40 miles
At 12 am, Car A is at 90 miles and Car B is at 80 miles
At 1 pm, Car A and B are tied for 120 miles
The very second after Car B passes Car A
Answer: 1:01 pm Car B Passes Car A
I hope this helps you
1)
a) 18/50
b) 6.1/3=2
c) 9/2.8/3=3.4=12
2)
1 1/2=1.2+1/2=3/2
3 3/4=3.4+3/4=15/4
if we can 12 muffins with 3/2 cups
how many muffins with 15/4
?.3/2=12.15/4
?=30 muffins
First, determine the z-score of 675.
z = (675 - 500) / 100 = 1.75
The z-score of 500 is,
z = 0.
Subtracting the z-scores will give us 1.75. This is equal to 0.9599.
= 0.9599 - 0.5 = 0.4599
Multiplying this to the given number of light bulbs,
n = 0.4599 x 5000 = 2299.5
Therefore, there is approximately 2300 light bulbs expected to last between 500 to 675 hours.
it would be convenient if you actually give us the equation
