Answer:
8 hours
Step-by-step explanation:
t = time for Bob and Nina to make 60 leashes
Bob = 7 in 2 hr = 3.5 in 1 hr
Nina = 4 in 1 hr
3.5 + 4 = 7.5 leashes per hour
t = 60/7.5 = 8 hours
A banana costs three times as much as an apple. The total cost of 1 banana and 1
apple is $1.60. If a represents the cost of 1 apple, which equation could you use to
find a?
Answer:
banana cost 1.20 and the apple cost 0.4
Step-by-step explanation:
1.60 divided by 4 = 0.4 and the cost of apples
1.60 - 0.4 = 1.2 and the cost of bananas
since the banana cost three times you divide by two and subtract that number from the total cost to get three times the amount of the apples price. hope this helped sorry for my spelling

A fisherman illegally drops some fish into a pond, and they quickly propagate (reproduce). The population
growth of the new specifies is modeled by P(x) =6(b)^x where x is the time in weeks following the moment
he dropped the fish into the pond and b is a positive unknown base. Suppose that b is 3. Graph this
relationship. How long does it take for there to be at least 100 fish in the pond?
Answer:
C. About 6 days
Step-by-step explanation:
Here the function that shows the population of fish after x weeks,
Where b is any unknown,
If b = 3,
Then, the function is,
Which is a exponentially increasing function,
That having y-intercept = (0,1)
And, horizontal asymptote,
y = 0
End behavior of the function:
As ,
As ,
Thus, by the above information we can graph the given relation.
Now, For at least 100 fish in the pound,
By taking log on both sides,
Thus, after 0.8567 weeks (approx) the fish on the pound will be at least 100.
1 week = 7 days,
0.8567 weeks = 5.9969 days ≈ 6 days
Hence, after 6 days (approx) the fish on the pound will be at least 100.

if eight times a number is increased by 3 the result is 19 more than six times this digit. find the number
Answer:
8
Step-by-step explanation:
Even though we don't know the number yet, let's name this number "n".
8n + 3 = 6n + 19
8n + 3 - 6n = 6n + 19 - 6n
2n + 3 = 19
2n = 16
n = 16/2
n = 8
Our number is 8.
Note: This answer is 100% correct.

Question
Solve the real-world situation by using the substitution method.
Jen is riding her bicycle on a trail at the rate of 0.33 kilometer per minute. Michelle is 8
kilometers behind Jen when she starts traveling on the same trail at a rate of 0.43 kilometer
per minute. Let d represent the distance in kilometers the bicyclists are from the start of
the trail and t represent the time in minutes.
The system of equations
d = 0.33t + 8
d = 0.43t
can be used to represent this situation.
р.
How many minutes will it take Michelle to catch up to Jen? How far will they be from the
start of the trail? Use the substitution method to solve this real-world application.
Michelle will catch up to Jen in
of the trail.
minutes and they will be
km from the start
9514 1404 393
Answer:
80 minutes34.4 kmStep-by-step explanation:
Use the second equation to substitute for d in the first equation.
0.43t = 0.33t +8
Subtract 0.33t from both sides
0.10t = 8
Multiply by 10
t = 80 . . . . . . Michelle will catch Jen in 80 minutes
The distance traveled will be ...
d = 0.43t = 0.43×80 = 34.4 . . . . km
The girls will have traveled 34.4 km when they meet.

solve using the quadratic equationX^2 -4x -3 =0
Answer:
[tex]x = 2[/tex] ± [tex]\sqrt{7}[/tex]
Step-by-step explanation:
Lets see the quadratic equation :
x = -b ± [tex]\sqrt{b^2 - 4ac}[/tex] / 2a
So now we have our quadratic :
[tex]x^2 - 4x - 3 =0[/tex]
a = ?^2 (Exponent)
b = ?x (Variable)
c = ? (Constant)
So replace every variable in the quadratic equation with the ones in the quadratic formula.
x = -(-4) ± (-4)^2 - 4(1)(-3) / 2(1)
(Imagine (-4)^2 - 4(1)(-3) in a square root)
x = 4 ± [tex]\sqrt{16 - - 12}[/tex] / 2
x = 4 ± [tex]\sqrt{28}[/tex] / 2
Of course 28 isn't available for a square root property, so lets break it up :
x = 4 ± [tex]2\sqrt{7}[/tex] / 2
Simplify the radical :
[tex]x = 2[/tex] ± [tex]\sqrt{7}[/tex]
