Two customers took out car loans from a bank.
Robert took out a 4-year loan for $30,000 and paid 4.9% annual simple interest.
Susan took out a 6-year loan for $30,000 and paid 4.5% annual simple interest.
What is the difference between the amounts of interest Robert and Susan paid for their car loans?
Enter your answer in the box.
$ { }
Answer:
Susan pays $2220 more interest than Robert
Step-by-step explanation:
Interest = principle times rate times the time
I = PRT
Robert: I = 30000(.049)(4) = $5880
Susan: I = 30000(.045)(6) = $8100
8100 - 5880 = $2220

Answer:
3x - y = -3
Step-by-step explanation:
divide everything by 4, the greatest common factor. That's all you need to do.
Answer: y=3x+3
Step-by-step explanation:
12x -4y= -12
subtract 12x from both sides
-4y= -12x-12
Divide everything by -4 to make y positive and alone
y=3x+3

A small radio station can broadcast in a circular range with a radius of 20 miles. About how many square miles is the area covered by this range? Use 3.14 for π.
The requried range of the radio station is given as 1256 square miles.
What is an area circle?The area of the circle is given by the pie times square of the radius.
A = πr², where r is the radius of the circle.
Here,
A small radio station can broadcast in a circular range with a radius of 20 miles.
The range is given by the area of the circle with given radius,
Area of the circle = πr²
Area of the circle = 3.14 × 20²
area of the circle = 1256 square miles
Thus, the requried range of the radio station is given as 1256 square miles.

Step-by-step explanation:
The diameter of a circle has endpoints (2,-6) and (-4,-16).
Enter an equation for the circle in standard form.
Answer:
[tex](x + 1)^{2} + (y + 11)^{2} = 34[/tex]
Step-by-step explanation:
First find the midpoint of the segment from (2, -6) to (-4, -16)
((2 - 4)/2, (-6 - 16)/2)
(-2/2, -22/2)
(-1, -11) is the midpoint and is the center of the circle
Now find the distance between the 2 given points and divide by 2 to get the radius of the circle
d = [tex]\sqrt{(2 + 4)^{2} + (-6 + 16)^{2} }[/tex]
= [tex]\sqrt{6^{2} + 10^{2} }[/tex]
= [tex]\sqrt{36 + 100}[/tex]
= [tex]\sqrt{136}[/tex]
r = [tex]\sqrt{136}[/tex]/2
[tex]r^{2}[/tex] = 136/4 = 34
Equation of circle with center at (-1, -11) and radius = [tex]\sqrt{34}[/tex] is
[tex](x + 1)^{2} + (y + 11)^{2} = 34[/tex]
A salesperson's commission rate is 5%. What is the commission from the sale of $36,000 worth of furnaces? Use pencil and paper. Suppose sales would double. What would be true about the commission? Explain without using any calculations.
Answer:
a. $1,800
b. Commission would double as well.
Step-by-step explanation:
Commission paid on $36,000 worth of furnaces with a rate of 5% is:
= Amount of sales * commission rate
= 36,000 * 5%
= $1,800
If the sales were to double, the commission would be based on double the amount so it would double as well.
= 36,000 * 2
= $72,000
Commission = 72,000 * 5%
= $3,600
Commission therefore doubled.
Answer:
1,800

triangles and rectangle
Step-by-step explanation:
Area of triangle (A1)
= 1/2 * b *h
= 1/2 * 1 * 1
= 1/2 ft
Area of rectangle (A2)
= L * b
= 3 *1
= 3 ft
Total area
= A1 + A2
= 1/2 + 3
= (1 + 6 ) / 2
= 7/2 ft²
= 3.5 ft²

i need help asap! math problem
Answer:
4
Step-by-step explanation:
cos(-π) = -1 [in radians]
3-(-1) = 4
There are many ways to answer this but, I'll try to explain it.
You can see that you are computing a limit when some n approaches negative PI. You get to substitute negative PI instead of n and compute cos(-pi) which is -1.
Then compute f(x) - (-1) = 3 - (-1) = 4 which is a result.
The way you can imagine cos(-pi) or cos(-90deg) is by dragging point in a unit circle beneath x-axis and to the bottom y-axis (-90 angle), the y coordinate tells you the cosine value at (-90) and because you have dragged the point on the unit down to y-axis the value is -1.
Hope this helps.

Find the marginal distribution of gender in counts.
Complete question :
Mavis is interested in whether military dependency is related to gender in American Samoa. Here is data she collected about the population of American Samoa in 2010.
Millitary status _________ female ____ Male
In armed forces _________ 28 _______ 59
Millitary dependent ______ 928 ______ 781
Civilian _______________ 26393 ___27330
Answer:
Male = 0.4193
Female = 0.5087
Step-by-step explanation:
To obtain the marginal distribution of gender :
Total number of civilians (male + female)
(26393 + 27330) = 53,723
Male :
P(male) = number of male / total
P(male) = 26393 / 53,723 = 0.4912793
P(Female) = number of Female / total
P(Female) = 27330 / 53,723 = 0.5087206

A ball is thrown into the air with a speed of 32 feet per second. The function h=32t - 16t^2 models the height of the ball after t seconds. How many seconds does it take for the ball to reach its maximum height?
Answer:
t = 1 s
Step-by-step explanation:
The function models the height of the ball after t seconds is given by :
[tex]h=32t - 16t^2[/tex]
We need to find how many seconds does it take for the ball to reach its maximum height.
For maximum height put dh/dt = 0
[tex]\dfrac{dh}{dt}=\dfrac{d}{dt}(32t - 16t^2)\\=32-32t[/tex]
So,
32-32t = 0
t = 1
So, it will take 1 second to reach its maximum height.
