The loan amount at 9% interest is $48,000.
The loan amount at 12% interest is $17,000
What are the loan amounts?The first step is to form a system of equations that can be used to determine the required values:
0.09a + 0.12b = $6,360 equation 1
a + b = $65,000 equation 2
Where:
a = amount of the loan at 9% interest
b = amount of the loan at 12% interest
What is each loan amount?Multiply equation 2 by 0.09
0.09a + 0.09b = 5850 equation 3
Subtract equation 3 from equation 2
0.03b = 510
Divide both sides of the equation by 0.03
b = 510 / 0.03
b = $17,000
Subtract 17,000 from 65,000
a = 65,000 - 17,000
a = $48,000

1ai. x^2 less than or equal to sign 8
1ei. (x-4)(x+1)>0
Answer:
1ai. x is less than or equal to 8
1ei. x > 4 and x > 1
Step-by-step explanation:
Steps for solving 1ai
Factor x² less then or equal to 8 you would do this by finding two numbers the product is equal to zero and the sum would equal to zero. You would find all factors that would equal to your terms like for example x² has the factors x•x and the factors of 0 are 0 so it would be (x+0)(x+0) is less than or equal to 8Split the factoed terms into two inequalities since you're dealing with polynomial inequalities you will either have one or more solutions. For example you will have to solve x + 0 is less than or equal to 8 Solve for x by doing the inverse operation in this case the addition will become subtraction so it will be x + 0-0 is less than or equal to 8 - 0 which would be x is greater than or equal to 8Steps to solve 1ei
Split the factored terms into 2 inequalities so (x-4) (x+1) >0 will become x-4>0 and x+1>0 Solve for x in this case x-4>0 will become x-4+4> 0+4 which is x>4 and x+1>0 will be x+1-1>0-1 which is x>-1

-9x+10y=25 7x-4y=7 Elimination method (with work)
Values of x and y in the given equations by elimination method are 5 and 7 respectively. that is, x=5 and y=7.
In the elimination method, the aim is to entirely remove one of the unknown variable which would eventually make it easier to calculate be other unknown. However, it is important to note that this method is most effective when neither of the coefficients is equal to 1. The coefficient of either of the two variables will be made the same in both equations and by subtracting one from the other, it would be eliminated. It is a non-graphical methods of solving simultaneous linear equations.
consider the equations as (1) and (2),
-9x+10y=25..........................(1)
7x-4y=7............................(2)
Now, multiply equation (1) by 4 and equation (2) by 10
Let the equations we get now be (3) and (4),
-36+40y=100......................(3)
70x-40y=70........................(4)
We can see that the coefficient of y in both equations is same that is 40
Now, add equation (3) and (4)
-36+40y+70x-40y=100+70 ( y terms cancel out)
By evaluating we get,
-34x=170
x=-170/34
x=5
To find the value of y, substitute value of x in equation (2)
7x-4y=7
7*5-4y=7
35-4y=7
35-7=4y
28=4y
y=28/4
y=7
Therefore, we can conclude that the values of x and y in the given equations -9x+10y=25 and 7x-4y=7 by elimination method are 5 and 7 respectively. that is, x=5 and y=7.

In the lab, Lena has two solutions that contain alcohol and is mixing them with each other. She uses 400 milliliters less of Solution A than Solution B.
Solution A is 20% alcohol and Solution B is 17% alcohol. How many milliliters of Solution B does she use, if the resulting mixture has 179 milliliters of
pure alcohol?
Using a system of equations, it is found that she uses 700 ml of Solution B.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For this problem, the variables are given as follows:
Variable x: Number of ml of Solution A.Variable y: Number of ml of Solution B.She uses 400 milliliters less of Solution A than Solution B, hence:
x = y - 400.
Solution A is 20% alcohol and Solution B is 17% alcohol. The esulting mixture has 179 milliliters of pure alcohol, hence:
0.2x + 0.17y = 179.
Since x = y - 400, we have that:
0.2(y - 400) + 0.17y = 179.
0.37y = 259
y = 259/0.37
y = 700.
She uses 700 ml of Solution B.

Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures, involving operations such as division and multiplication, as they involve unit rates.
Since the classes have equal width, the width is given as follows:
class width = (max - min)/n
In which n is the number of classes.
Hence, from the data given in this problem, the class width is given as follows:
class width = (30 - 1)/6 = 4.8333.
The lowest class starts at 1, hence, adding 4.8333, we have that:
The lower class limits are given as follows: 1, 5.8333, 10.6667, 15.5, 20.3333, 25.1665
The highest class starts at 30, hence, subtracting 4.8333, we have that:

The values of the sine and tangent of the angle are √2 / 2 and - 1. By using inverse trigonometric functions, the value of angle is 135° (3π / 4).
How to find the values of other trigonometric functions and the angle behind themAccording to the statement, the cosine of the angle is in the second quadrant and therefore the value of the sine must be positive and the value of the tangent must be negative. Then, the value of the sine is found by the fundamental formula:
sin θ = √(1 - cos² θ)
sin θ = √[1 - (- √2 / 2)²]
sin θ = √(1 - 1 / 2)
sin θ = √(1 / 2)
sin θ = √2 / 2
And the value of the tangent:
tan θ = sin θ / cos θ
tan θ = (√2 / 2) / (- √2 / 2)
tan θ = - 1

Converting
Write the number of grams. Label it "grams" or "g." If you're using a calculator, just type the number in.
In this section, we'll follow along with an example problem to make things easier. Let's say that we want to convert 20,000 grams to kilograms. To start, we would write "20,000 grams" on our paper.
Divide by 1,000. A kilogram is one thousand grams. This means that to get kilograms from grams, you just need to divide the number of grams by 1,000.
In our example, we would get kilograms by dividing 20,000 grams by 1,000.
20,000/1,000 = 20
Label your answer. Don't forget this step! Labelling your answer with the proper units is important. If you're doing this conversion for schoolwork, you can lose points if you don't label. If you're doing it for something else, people may assume the wrong units.
In our case, we would label our answer with the label "kilograms" like this:
20 kilograms.
To get back to grams, multiply by 1,000. As discussed above, a kilogram is one thousand grams. This means that if you ever want to get back to grams from kilograms, all you need to do is multiply the number of kilograms by 1,000. Since multiplications is basically the "opposite" operation as division, this will "undo" the division and give you grams.
To get 20 kilograms back to grams, we just multiply by 1,000 (don't forget to label your answer again):
20 kilograms × 1,000 = 20,000 grams
Converting by Shifting the Decimal Point
Start with your number of grams. Believe it or not, you can convert between grams and kilograms without doing any math. This works because the metric system is a base 10 system of measurements. In other words, metric units are always a multiple of 10 apart from each other — there are 10 millimeters in a centimeter, 100 centimeters in a meter, 1,000 meters in a kilometer, and so on.
In this section, let's convert 37 grams to kilograms. We would begin the same way as in the section above, writing "37 grams" on our paper.
Shift the decimal point three spaces to the left. Now, find the decimal point in your number of grams. If you're converting a whole number, this won't usually be written, but you can assume it its to the right of the ones place. Move the decimal point three spaces to the left. Each time you move past a number counts as one space. If you run out of numbers to move past, keep moving it, leaving blank spaces.
In our example, the decimal point in 37 grams is to the right of the 7 (i.e., 37 grams is the same as 37.0 grams). If we go one space at a time, moving the decimal point three spaces to the left looks like this:
37.
3.7
.37
._37 — note that we leave an empty space when we run out of numbers.
Add zeroes in any empty spaces. You can't leave empty spaces in your answer, so fill in each one with a zero. You can also put a zero to the left of the decimal place if there aren't any numbers there, but this is optional — it just depends how you like to write your answers.
In our example, we have one empty space between the decimal point and the 3, so we'll fill it in with a zero like this:
.037
Adding the proper label (plus an extra zero to the left of the decimal point for presentation purposes), we get our final answer:
0.037 kilograms
To get back to grams, shift the decimal place back. When you have kilograms, shifting the decimal place three spaces to the right will give you grams again. Fill in any empty spaces with zeroes as normal.
In our example, we can shift the decimal place three spaces to the right like this:
0.037
00.37
003.7
0037. — the zeroes on the left don't matter any more, so we can rewrite this as simply 37 grams.
