Scott gets a student loan to go to college after high school. If he pays $750 in interest at a rate of 3% over four years, how much must the loan have been for originally?
Answer:
$6250
Step-by-step explanation:
Step one:
given data
simple intereest= $750
rate= 3%
time= 4years
Required
The Principal P
Step two:
SI= PRT/100
750= P*3*4/100
750=12P/100
cross multiply we have
12P=750*100
divide both sides by 12
P=75000/12
P=$6250

Answer:
Step-by-step explanation:
Easy way to do it is to look at the constant, the number that does not have a variable, and that will be your y-intercept, so that is your first point. Then, you take your slope and do rise over run. For example, if the slope is 1/4, then you would rise up one, and run right 4. If the slope was -1/2, then you would rise up one, and run left 2, or rise down one and run right 2. This will give you your second and third points and you can easily graph your line from there.

Answer:
x = 12
∠A = 144°
Step-by-step explanation:
Because of the alternate exterior angles theorem, ∠A and ∠B are equal, so:
10x + 24 = 6x + 72
subtract 24 from both sides
10x = 6x + 48
subtract 6x from both sides
4x = 48
divide both sides by 4
x = 12
So ∠A is
10(12) + 24 = 120 + 24 = 144
∠A and ∠B are both 144, no need to do this to ∠B as like i said before, they are congruent, but just in case
6(12) + 72 = 72 + 72 = 144

[tex] \underline{ \underline{ \text{question}}} : [/tex] Find the equation of straight line which cuts off an intercept 2 from the Y - axis and whose perpendicular distance from the origin is 1.
Answer:
[tex]y=-\sqrt{3}x+2[/tex]
Step-by-step explanation:
We want to find the equation of a straight line that cuts off an intercept of two from the y-axis and whose perpendicular distance from the origin is one.
Let Point M be (x, y). As we know, Point R will be (0, 2) and Point O (the origin) will be (0, 0).
First, we can use the distance formula to determine values for M. The distance formula is given by:
[tex]\displaystyle d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Since we know that the distance between O and M is one, d = 1:
And we will let M(x, y) be (x₂, y₂) and O(0, 0) be (x₁, y₁). So:
[tex]\displaystyle 1=\sqrt{(x-0)^2+(y-0)^2}[/tex]
Simplify:
[tex]1=\sqrt{x^2+y^2}[/tex]
We can solve for y. Square both sides:
[tex]1=x^2+y^2[/tex]
Rearranging gives:
[tex]y^2=1-x^2[/tex]
Take the square root of both sides. Since M is in the first quadrant, we only need to worry about the positive case. Therefore:
[tex]y=\sqrt{1-x^2}[/tex]
So, Point M is now given by (we substitute the above equation for y):
[tex]M(x,\sqrt{1-x^2})[/tex]
We know that Segment OM is perpendicular to Line RM.
Therefore, their slopes will be negative reciprocals of each other.
So, let’s find the slope of each segment/line. We will use the slope formula given by:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Segment OM:
For OM, we have two points: O(0, 0) and M(x, √(1-x²)). So, the slope will be:
[tex]\displaystyle m_{OM}=\frac{\sqrt{1-x^2}-0}{x-0}=\frac{\sqrt{1-x^2}}{x}[/tex]
Line RM:
For RM, we have the two points R(0, 2) and M(x, √(1-x²)). So, the slope will be:
[tex]\displaystyle m_{RM}=\frac{\sqrt{1-x^2}-2}{x-0}=\frac{\sqrt{1-x^2}-2}{x}[/tex]
Since their slopes are negative reciprocals of each other, this means that:
[tex]m_{OM}=-(m_{RM})^{-1}[/tex]
Substitute:
[tex]\displaystyle \frac{\sqrt{1-x^2}}{x}=-\Big(\frac{\sqrt{1-x^2}-2}{x}\Big)^{-1}[/tex]
Now, we can solve for x. Simplify:
[tex]\displaystyle \frac{\sqrt{1-x^2}}{x}=\frac{x}{2-\sqrt{1-x^2}}[/tex]
Cross-multiply:
[tex]x(x)=\sqrt{1-x^2}(2-\sqrt{1-x^2})[/tex]
Distribute:
[tex]x^2=2\sqrt{1-x^2}-(\sqrt{1-x^2})^2[/tex]
Simplify:
[tex]x^2=2\sqrt{1-x^2}-(1-x^2)[/tex]
Distribute:
[tex]x^2=2\sqrt{1-x^2}-1+x^2[/tex]
So:
[tex]0=2\sqrt{1-x^2}-1[/tex]
Adding 1 and then dividing by 2 yields:
[tex]\displaystyle \frac{1}{2}=\sqrt{1-x^2}[/tex]
Then:
[tex]\displaystyle \frac{1}{4}=1-x^2[/tex]
Therefore, the value of x is:
[tex]\displaystyle \begin{aligned}\frac{1}{4}-1&=-x^2\\-\frac{3}{4}&=-x^2\\ \frac{3}{4}&=x^2\\ \frac{\sqrt{3}}{2}&=x\end{aligned}[/tex]
Then, Point M will be:
[tex]\begin{aligned} \displaystyle M(x,\sqrt{1-x^2})&=M\left(\frac{\sqrt{3}}{2}, \sqrt{1-\left(\frac{\sqrt{3}}{2}\right)^2}\right)\\ \\ M&=\left(\frac{\sqrt3}{2},\frac{1}{2}\right)\end{aligned}[/tex]
Therefore, the slope of Line RM will be:
[tex]\displaystyle \begin{aligned}m_{RM}&=\frac{\dfrac{1}{2}-2}{\dfrac{\sqrt{3}}{2}-0} \\ \\ &=\frac{\dfrac{-3}{2}}{\dfrac{\sqrt{3}}{2}}\\ \\ &=-\frac{3}{\sqrt3}\\ \\&=-\sqrt3\end{aligned}[/tex]
And since we know that R is (0, 2), R is the y-intercept of RM. Then, using the slope-intercept form:
[tex]y=mx+b[/tex]
We can see that the equation of Line RM is:
[tex]y=-\sqrt{3}x+2[/tex]

A bag contains 120 marbles. Some are red and the rest are black. There are 19 red marbles for every black marble.
How many red marbles are in a bag
Answer:
There are 114 red marbles

The ratio of red to black marbles is 19:1
19+1+20
20 units+120
1 unit= 120/20=6
19 units=120-6=114
There for you have 114 red marbles.

Alexis bought a CD player. She does not remember the price, but she does know that the 5% sales tax came to $4.80. What was the price of the CD player?
Answer:
Price of CD player = $96
Step-by-step explanation:
Given:
Sales tax = 5%
Amount of sales tax = $4.80
Find:
Price of CD player
Computation:
Price of CD player = Amount of sales tax / Sales tax
Price of CD player = 4.8 / 5%
Price of CD player = $96
A line passes through A(6,5) and B(4,2) find equation of a line parallel to AB and passes through (7,10)
Answer:
2y = 3x-1
Step-by-step explanation:
Here, we want to find the equation of the line
We start by calculating the slope of the segment AB
mathematically, that will be
m = (y2-y1)/(x2-x-)
m = (2-5)/(4-6) = 3/2
Since the two lines are parallel, their slopes must be equal
We simply insert this value into the point-slope form
y-y1 = m(x-x1)
y-10 = 3/2(x-7)
Multiply through by 2
2y-20 = 3x - 21
2y = 3x-21 + 20
2y = 3x -1

P.S Can I have brainliest?
Can anyone plz help me plz:
please help me very much needed :((
Answer:
The correct answer is equation 1
Step-by-step explanation:
First put 11 million in scientific notation. 1 million is 10^6. But 11 isn't scientific notation, you need 1.1 which means you need an extra 10...so 1.1 x 10^7.
Then you multiply that with growth rate, which is (1+0.05)^10.
It is 0.05 since it grows at 5% where 5% of 100 is 0.05. And exponent is 10 because you want to know the population 10 years from now, so you multiply the growth rate 10 times.

If f(x) =2x + 7 and g(x) = x² -2, what is [fo gl(3)?
-7
-1
1
7
will mark as brainly !!
Answer: -7
Step-by-step explanation:
Plug in 3 for x^2-2, you would then get 7 since 3^2 is 9 and you subtract it to get the answer for g(x). Plug in that number for f(x) and you would get -7 as a result. -2(7) would equal to -14 since you are multiplying a positive and negative and adding it will still be -7 which makes your initial answer wrong.
