Answer:
The total payment Janie have to make is $5466 .
Step-by-step explanation:
Given as :
The loan principal = $4850
The rate of interest applied = 13.8% compounded monthly
Let The time period of loan = t years
The monthly payment she make = $455.50 each month
I.e She make payment for t years = $455.50 × n
where n is the number of terms
From Compound Interest
Amount = Principal × [tex](1+\dfrac{\textrm rate}{12\times 100})^{12\times time}[/tex]
Or, $455.50 × n = $4850 × [tex](1+\dfrac{\textrm 13.8}{12\times 100})^{12\times time}[/tex]
Or, [tex]\dfrac{455.50}{4850}[/tex] × n = [tex](1.0115)^{12\times 1}[/tex]
Or, 0.0939 × n = [tex](1.0115)^{12}[/tex]
Or, 0.0939 × n = 1.14707
∴ n = [tex]\dfrac{1.14707}{0.0939}[/tex]
I.e n = 12.21 ≈ 12
So, The number of terms Janie she will pay = 12
So, The total payment she have to make = $455.50 × 12 = $5466
Hence The total payment Janie have to make is $5466 . Answer
Answer:
She will have to make 12 payments

the population P of a bacteria culture is modeled by P=4300e^kt, where t is the time in hours. If the population of the culture was 5800 after 40 hours, how long does it take for the population to double?
Answer:
93 h
Step-by-step explanation:
P = 4300eᵏᵗ
1. Calculate the value of k
lnP = ln4300 + kt
ln5800 = ln4300 + k(40 h)
8.666 = 8.366 + 40k h
8.666 - 8.366 = 40k h
0.299 = 40 k h
k= 0.299/40 h = 7.481 × 10⁻³ h⁻¹
2. Calculate the time for the population to double
2 × 4300 = 4300eᵏᵗ
2 = eᵏᵗ
ln2 = kt
t = ln2/k = ln2/(7.481 × 10⁻³ h⁻¹) = 93 h
It takes 93 h for the population to double.

a dozen apples cost$4.92 for a dozen apples is a ratio of what per Apple
Final answer:
Each apple costs 41 cents when a dozen apples are bought for $4.92, determined by dividing the total cost by the number of apples.
Explanation:
The question asks to find the cost per apple when a dozen apples are purchased for $4.92. To find the cost per individual apple, you divide the total cost by the number of apples. There are 12 apples in a dozen, so:
$4.92 ÷ 12 apples = $0.41 per apple
So, each apple costs 41 cents. This exercise of finding the individual cost from a total is an example of a ratio used in basic arithmetic, often taught in middle school mathematics.
3,495 rounded to the nearest thousands
Answer:
The answer is 3000.
Step-by-step explanation:
Start to count from ones->tens->hundreds->thousands (from right to left). When it says nearest thousands, you should look at the previous no. which is in hundreds place. As the no. at hundreds place is lesser than 5, there's nothing to add up. (If no. is greater than 5, you should add 1 to the thousands place)
what is 21.6 rounded to the nearest whole number
Answer:
22
Step-by-step explanation:
21.6 would round up because 6 is closer to 10 than it is 0
The number 21.6 rounded to the nearest whole number is 22.
What is Rounding Off?Rounding off of a number is defined as the simplification of the number by keeping the value of the number same but is made closer to the next number.
Rounding can be done for whole numbers as well as decimals.
Given a number 21.6.
We have to round the number.
Here the first digit after the decimal place is 6, which is greater than 5.
So we have to add 1 to the last digit in the whole part.
So 21.6 is rounded to 22 to the nearest whole number.
Hence the correct number is 22.

Angeline made a dish with 5 1/3 cups of pasta. One serving is 0.2 cups. How many servings of pasta were in the dish Angeline made?
Answer:
26 2/3
Step-by-step explanation:
We could turn both of these numbers into decimals, but I find fractions easier.
so 5 1/3 as an improper fraction is 16/3
0.2 as a fraction is 2/10 or 1/5
so now we have the equation 16/3 ÷ 1/5 or 16/3 x 5/1
this give me 80/3, then when simplified gives me 26 2/3.
Leah has 280 toy cars she puts gift bags of toys together to sell at the flea market. She puts exactly 6 toys in each bag . She only sells full bags of toys. How many full bags of toys can she sell
Final answer:
Leah can make 46 full bags of toy cars to sell at the flea market when placing 6 toys in each bag out of her 280 toy cars, with 4 toys remaining unsold.
Explanation:
Leah has 280 toy cars and wants to sell them in gift bags, with 6 toys in each bag. To find out how many full bags she can sell, we need to divide the total number of toy cars by the number of toys per bag.
The calculation would be 280 ÷ 6 = 46 R4. This means Leah can make 46 full bags of toys and there will be 4 toys left over. Since she only sells full bags, the 4 extra toys will not be sold.

The measure of the supplement of an angle is 12° less than twice the measure of the angle. What is the measurement, in degrees, of the angle and its supplement?
The measurement of the angle is ______ degrees.
The measurement of the supplement is ______ degrees.
Answer:
The measure of the angle is 64 degree.
The measure of the supplement is 116 degree.
Step-by-step explanation:
Let the measure of the angle be 'x'.
Given:
Supplement of the angle is 12 less than twice the measure of the angle.
Twice the angle means 2 times of the angle which is [tex]2x[/tex] and 12 less means 12 is subtracted from [tex]2x[/tex].
So, supplement of the angle = [tex]2x-12[/tex]
Now, by definition of supplementary angles, if two angles are supplement of one another, then their sum is 180 degrees.
Therefore, the sum of the given angles = 180°
⇒ [tex]x+2x-12=180[/tex]
⇒ [tex]3x-12=180[/tex]
⇒ [tex]3x=180+12[/tex]
⇒ [tex]3x=192[/tex]
⇒ [tex]x=\frac{192}{3}=64\°[/tex]
The measure of the supplement = [tex]2(64)-12=128-12=116[/tex]
The measure of the angle is 64 degree.
The measure of the supplement is 116 degree.

The coffee shop is having a special where 2 pounds of coffee cost four dollars. Assume that the total cost in dollars y varies directly with the number of pounds of coffee x. This can be represented by y=2x. How much will 2.5 pounds of coffee cost
Answer:
Step-by-step explanation:
If 2 pounds costs $4, then 1 pound costs $2. That's why the equation is y = 2x and x is the number of pounds you buy. If you buy 2.5 pounds, then the cost is y = 2(2.5) so
y = $5
20% of a number is 35 what is the number
Solve for x.
20% × x = 35
0.2x=35
x=175
answer: 175
Answer: 175
Step-by-step explanation: We can change this problem to mean the same thing but it will say 20% of what number is 35.
To answer the question 20% of what number is 35, we translate the question into an equation. First we have 20% which we need to write as a decimal and remember to write 20% as a decimal, we move the decimal point 2 places to the left and we get 0.20.
Next we have "of what number" that's times x, "is 35" = 35. Now we have the equation (.20)(x) = 35.
Not to solve for x, since x is being multiplied by .20, we need to divide by .20 on both sides of the equation. On the left side of the equation the .20's cancel and we have x. On the right side of the equation we have 35 divided by .20 which is 175.
This means that 20% of 175 is 35.

Find f(x) and g(x) so that the function can be described as y = f(g(x)).
y= 8/sqareroot of 2x+4
f(x) = 8, g(x) = square root of quantity two x plus four.
f(x) = square root of quantity two x plus four., g(x) = 8
f(x) = eight divided by x., g(x) = 2x + 4
f(x) = eight divided by square root of x., g(x) = 2x + 4
Answer:
The fourth option gives the result.
Step-by-step explanation:
We have to find f(x) and g(x) from options given such that y = f[g(x)] is equivalent to [tex]y = \frac{8}{\sqrt{2x + 4}}[/tex].
Here, the fourth option gives the result.
If [tex]f(x) = \frac{8}{\sqrt{x} }[/tex] and g(x) = 2x + 4, then the composite function [tex]f[g(x)] = \frac{8}{\sqrt{2x + 4}}[/tex]

Step-by-step explanation:
Given equation is:
[tex]3x^2+3x+5 = 0[/tex]
We will use the quadratic formula for solving the given equation
The quadratic formula is:
[tex]x = \frac{-b+\sqrt{b^2-4ac}}{2a}\ \ \ ,\ \ \ x = \frac{-b-\sqrt{b^2-4ac}}{2a}[/tex]
Here,
a = 3
b = 3
c = 5
[tex]x = \frac{-3+\sqrt{(3)^2-4(3)(5)}}{2(3)}\ \ \ ,\ \ \ x = \frac{-3-\sqrt{(3)^2-4(3)(5)}}{2(3)}\\x = \frac{-3+\sqrt{9-60}}{6}\ \ \ ,\ \ \ x = \frac{-3-\sqrt{9-60}}{6}\\x = \frac{-3+\sqrt{-51}}{6} \ \ \ , \ \ \ \ x = \frac{-3-\sqrt{-51}}{6}[/tex]
As we know
[tex]i = \sqrt{-1}[/tex]
So,
[tex]x=\frac{-3+\sqrt{51*-1}}{6} \ \ \ , \ \ \ \ x = \frac{-3-\sqrt{51*-1}}{6}\\x=\frac{-3+(\sqrt{51}*\sqrt{-1})}{6} \ \ \ , \ \ \ \ x = \frac{-3-(\sqrt{51}*\sqrt{-1})}{6}\\x = \frac{-3+\sqrt{51}i}{6}\ \ \ \ AND\ \ \ \ x = \frac{-3-\sqrt{51}i}{6}[/tex]
Hence,
The solution is:
[tex]x = \frac{-3+\sqrt{51}i}{6}\ \ \ \ AND\ \ \ \ x = \frac{-3-\sqrt{51}i}{6}[/tex]

Answer:
The slopes of the lines are different.
Step-by-step explanation:
If you do convert the standard form equation to slope-intercept form, you get ...
y = -x +5
You see that the slope of this line is -1, whereas the slope of the other line is +1. Both lines have a y-intercept of 5. It is the slopes that are different.
_____
You can determine this to be the case without converting the form of the equation if you have some practice with the various forms of the equation of a line.
In standard form, if the variable signs are the same, the slope is negative. Of course, in slope-intercept form, the sign of the slope is the sign of the coefficient of x.

The science club is inflating a model of a hot air balloon. The graph below shows their progress. At what rate is the diameter increasing?
Answer:
12.5 centimeters per minute
Step-by-step explanation:
From the graph, the rate at which the diameter increasing would be inthe units of cm/min
The rate is basically the slope of the line. The slope (m) has formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where
[tex](x_1,y_1)[/tex] is any point from the graph
and
[tex](x_2,y_2)[/tex] is another point from the graph
Let's take the origin (0,0) as the first point and (4,50) as the second point. Now lets calculate the slope:
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{50-0}{4-0}\\m=\frac{50}{4}\\m=12.5[/tex]
Thus, we can say:
The diameter of the hot air balloon is increasing at a rate of 12.5 centimeters per minute
