you are buying orange juice for $3.50 per container and have a gift card worth $5. the function f(x)=3.50x - 5 represents your total cost f(x) if you buy x containers of orange juice and use the gift card. How much would you pay for 4 containers of orange juice?
Answer:
You would pay 9 dollars because 4 times 3.5 is 14. If you subtract the 5 dollars from the gift card you're only paying 9 dollars out of pocket

Step-by-step explanation:
your bank account is -$58.44. you deposit $46.85. what is your new balance?
Answer:
-$11.59
Step-by-step explanation:
Bank account balance = -$58.44
Deposit $46.85.
New balance = Deposit + Bank account balance
New balance = $46.85 + -$58.44
New balance = $46.85 - $58.44
New balance = -$11.59

The number of bacteria at the beginning of an experiment was 30 and the bacteria grow at an hourly rate of 1.4 percent. Using the model given by () = 0e, estimate the number of bacteria, rounded to the nearest whole number after 20 hours.
Answer:
The estimated number of bacteria after 20 hours is 40.
Step-by-step explanation:
This is a case where a geometrical progression is reported, which is a particular case of exponential growth and is defined by the following formula:
[tex]n(t) = n_{o}\cdot \left(1+\frac{r}{100} \right)^{t}[/tex] (1)
Where:
[tex]n_{o}[/tex] - Initial number of bacteria, dimensionless.
[tex]r[/tex] - Increase growth of the experiment, expressed in percentage.
[tex]t[/tex] - Time, measured in hours.
[tex]n(t)[/tex] - Current number of bacteria, dimensionless.
If we know that [tex]n_{o} = 30[/tex], [tex]r = 1.4[/tex] and [tex]t = 20\,h[/tex], then the number of bacteria after 20 hours is:
[tex]n(t) = 30\cdot \left(1+\frac{1.4}{100} \right)^{20}[/tex]
[tex]n(t) \approx 39.616[/tex]
[tex]n(t) = 40[/tex]
The estimated number of bacteria after 20 hours is 40.
A cube has a volume of 125 square inches. What is the length of each edge?
Answer:
5 inches
Step-by-step explanation:
formula for cube volume is l^3
so 5^3 is equal to
5 x 5 x 5
which is
25 x 5
equals
125
Hope this helps!
Answer:
5 inches
Step-by-step explanation:
V=a^3
5^3 is 125 so the answer is 5

Substitute x = 3 - 2 cos(θ) and dx = 2 sin(θ) dθ (where "sin" = "sen"). So we have
∫ sin(θ) / (3 - 2 cos(θ)) dθ = 1/2 ∫ 1/x dx
= 1/2 ln|x| + C
= 1/2 ln(3 - 2 cos(θ)) + C
(We can remove the absolute value because -1 ≤ cos(θ) ≤ 1, so 1 ≤ 3 - 2 cos(θ) ≤ 5, and |x| = x when x ≥ 0.)

If a bike is going at 26 centimeters per second how many meters per minute is she traveling?
Answer:
15.6 meters in a minute
Step-by-step explanation:
Here's why:
1 centimeter= 0.01 meter
So, if you have 26 cm, that equals 0.26 meters.
Now, we know that there are 60 seconds in a minute.
So, we have to do 0.26 times 60 which equals 15.6 meters.
I hope this helps you! :)
Julie sent 200 emails last month. This month she sent 40% less. How many
emails did she send this month?
Answer:
She sent 120 emails this month.
Step-by-step explanation:
Multiply 200 by .60 (60 percent) and it will give you 120.
I used 60 instead of 40 because the problem said 40 percent less, NOT 40 percent of 200.

Answer:
66.4, 70.4, 223.2
Step-by-step explanation:
make the equation x + (x+4)+ 3x+24=360
then it's 5x+28=360
subtract 28 on both sides
5x=332
then divide by 5 on both sides
x=66.4
then, just plug in the numbers

You can buy 5 cans of green beans at the village market for $2.30, or you can buy 10 of them at Best Food for $5.10. Which place is the better buy?
Answer:
The village market
Step-by-step explanation:
Price per can at the village market
= 2.30÷5
= $0.46
Price per can at Best Food
=5.10÷10
= $0.51
Answer:
Village market
Step-by-step explanation:
Find the unit rate at village market and Best food and compare.
Village market:
Rate per can = 2.30 ÷ 5
= $ 0.46
Best food:
Rate per can = 5.10 ÷ 10
= 0.51
0.46 < 0.51
Buying can from village market is best buy as that is less priced

Write an equation and solve. You are saving money to buy a new iPad that costs $353. You have saved $225. How much more money do you need to save?
Answer: You have to save $128 more dollars.
Step-by-step explanation: The iPad costs $353 and you already have $225, so to find the answer you have you subtract what you already have from how much it costs. So 353 - 225 = 128. You need to save up $128 more dollars to get the iPad. (I think this is correct, I tried)
