Answer:
<h2>She was driving at 40.42 mph on average</h2>
Step-by-step explanation:
In this exercise, for us to find the speed that Chloe drives with we need to first convert the time she spent driving to hours completely since the time given is in hours and minute
Data
distance= 64 mile
time= 1hr 35min
to covert 1 hr 35 min to hours we have
= 1 + 35/60 (we are converting 35 min to hrs)
= 1+0.583
= 1.583
hence speed= 64/ 1.583
speed= 40.42 mph
She was driving at 40.42 mph on average
Answer:
Step-by-step explanation:
1.you have to set up a proportion(x/120 = 20%/100%
2.you have to cross multiply
3.you have to divide 100x by the number you get
4.you got your answer.
Answer:
The goat population reaches 1000 in 12.4 years
Step-by-step explanation:
After <em>t </em>years, the number of goats is given by
where 
is the initial number of goats and <em>b</em> is the per capita growth rate.
From the question,
- <em>b</em> = 0.5
- <em>N</em> = 1000
Answer:
x= -2, y = 5
Step-by-step explanation:
y = -4x-3
y = -2x+1
Set the two equations equal to each other
-4x-3 = -2x+1
Add 4x to each side
-4x-3 +4x = -2x+1+4x
-3 = 2x+1
Subtract 1 from each side
-3-1 = 2x+1-1
-4 =2x
Divide by 2
-4/2 = 2x/2
-2 =x
Now find y
y = -4x-3
y = -4(-2) -3
y = 8 -3
y =5
