It will take Ralph 5 hours to run 15 miles at a rate of 3/mph

Let's start by writing out their factors.
4: <em><u>1</u></em><em>, </em><em><u>2</u></em><em>, </em><em><u>4</u></em>
24: <em><u>1</u></em><em>, </em><em><u>2</u></em><em>, 3, </em><em><u>4</u></em><em>, 6, 8, 12, 24</em>
The greatest factor that
and
have in common is
.
Factor out
from both terms. 
Answer:
(1,-5)
Step-by-step explanation:
Answer: C. 541.60 hours
Step-by-step explanation:
Since the lifetime of a 2-volt non-rechargeable battery in constant use has a normal distribution, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = lifetime of the batteries.
µ = mean lifetime
σ = standard deviation
From the information given,
µ = 516 hours
σ = 20 hours
Looking at the normal distribution table, the z score corresponding to ninety percent approximately is 1.28
Therefore,
1.28 = (x - 516)/20
Cross multiplying by 20, it becomes
20 × 1.28 = x - 516
25.6 = x - 516
x = 516 + 25.6
x = 541.6
Therefore, Ninety percent of all batteries have a lifetime less than
541.60 hours
It will be $140.I say this because when you multiply $35 times 4 it equals $140.
