The Smith and Jones manufacturing company keeps a third of its cash in the bank, which pays 0.5% interest, and the other two-thirds in long-term investments that give 3.5% interest. If the company earned a total of $37,500 in interest last year, how much cash did they keep in the bank?
If the company earned a total of $37,500 in interest last year, how much cash did they keep in the bank is; $937,500.
How to solve Algebra Word Problems?This is about the concept of compound interest which is defined as the interest on savings that is calculated on both the initial principal and the accumulated interest from previous periods.
From the question, let us make x to represent the amount of cash.
Now, we are told that one portion of it pays 0.5%and as such this will be 0.005x.
Now, the other portion pays 3.5% and as such this is 0.035x.
Combining both knowing that the total the company earned in the last year was $37,500 and we have;
0.005x + 0.035x = 37500
0.040x = 37500
Solve for x to get;
x = (37500)/(0.04)
x = 937500
Therefore, the company started with $937,500.

The missing co-ordinate r = 8
(6,9) and (r,-1) are two points on a line whose slope is given as -5.
Slope of a line is the change of y co-ordinates divided by the change in x co-ordinates between two points on a line.
Take (x₁, y₁) = (6,9) and (x₂, y₂) = (r, -1).
The slope of a line is given by,
Slope, m = (y₂-y₁)/ (x₂-x₁)
⇒ -5 = (-1-9)/(r-6)
⇒ -5 = -10/(r-6)
⇒ 1 = 2/(r-6)
⇒ r-6 = 2
⇒ r = 2+6
⇒ r = 8
So the points are (6,9) and (8,-1).

layoff Ax + By = C is the usual form for two-variable direct equations. A standard form direct equation is, for case, 2x + 3y = 5. When an equation is given in this format, chancing both intercepts is rather simple( x and y). When trying to break systems involving two direct equations, this form is also relatively helpful.
Given
7x + 3 = 5 and y - 1 = 6
Add the bottoms from the two given equations to produce a single standard-form equation.
By shifting the constant fromR.H.S. toL.H.S., the equations are reset to zero.

7x - 2 = 0----( 1)
y - 1 = 6

In angle L M N the measure of angle L is equal to the measure of angle M. The measure of angle N is twice the measure of angle M. Find the measure of each angle in angle L M N
The measure of ∠M and ∠L is 45 degrees. then the measure of ∠N is 90 degrees.
How does an angle form?An angle requires two straight line/ line segments/rays, such that they're connected on one of their endpoints. The point of their joint is called vertex of that angle. Those two line segments forming it are called arms of that angle. The angle is the degree of rotation that it will take for the moving side to go from initial side to the position it is currently on.
Given that the angle L M N the measure of angle L is equal to the measure of angle M.
∠L = ∠M
Also, the measure of angle N is twice the measure of angle M.
∠N = 2∠M
The measure of each angle in angle L M N would be;
∠L + ∠M + ∠N = 180
∠M + ∠M + 2∠M = 180
4∠M = 180
∠M = 180/4
∠M = 45
∠M = ∠L = 45 degrees
∠N = 2 x 45 = 90
Therefore, the measure of ∠M and ∠L is 45 degrees. then the measure of ∠N is 90 degrees.

The relation that represents a function is the mapping in: B.
How to Determine if a Relation is a Function?A relation is defined as a function if each of the x-value (domain element of input) in the relation corresponds to exactly one y-value (range element of output).
The relation in option A is not a function because it has two different y-values, 7 and 5 that corresponds to an x-value, 6. The relations in option C and D do not represent a function also.
The mapping in option B shows a relation where each x-value (domain element) is related or corresponds to only one y-value (range element). Therefore, it is a function.

Answer:
x = 10
Step-by-step explanation:
The internal angles of a triangle sum 180°
74° + 45°+ (8x-19)° = 180°
119 + 8x - 19 = 180
119 - 19 + 8x = 180
100 + 8x = 180
8x = 180 - 100
8x = 80
x = 80/8
x = 10
Check:
74 + 45 + (8x-19) = 180
1100 + 8*10 = 180

The enrollment for a school in 2010 was 1245 students. in 2020, the enrollment was 715 students. find and interpret the rate of change in enrollment from 2010 to 2020
The rate of change in enrollment from 2010 to 2020 is -53 students per year.
Interpretation:
A negative rate of change (-53 students per year) means that the enrollment in the school decreased over the 10-year period from 2010 to 2020. On average, the school lost 53 students per year during this time frame. This decline in enrollment may have implications for the school's resources, budget, and programs, as it indicates a reduction in the student population over the given period.
Here, we have,
To find the rate of change in enrollment from 2010 to 2020, we can use the formula for calculating the rate of change:
Rate of change = (Change in enrollment) / (Time interval)
Where:
Change in enrollment = Enrollment in 2020 - Enrollment in 2010
Time interval = Year in 2020 - Year in 2010
Let's calculate the rate of change:
Change in enrollment = 715 - 1245 = -530
Time interval = 2020 - 2010 = 10 years
Rate of change = (-530) / 10 = -53
The rate of change in enrollment from 2010 to 2020 is -53 students per year.
Interpretation:
A negative rate of change (-53 students per year) means that the enrollment in the school decreased over the 10-year period from 2010 to 2020.

Charis invested 140$ . She earned a simple interest of 3%per year on the initial investment. If no money was added or removed from the investment, what was the amount of interest Charis received at the end of two years?
The amount of interest would be $8.4 Charis received at the end of two years.
What is the simple interest?Simple interest is defined as interest paid on the original principal and calculated with the following formula:
S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100
We have been given data as:
Principal (P) = $140
Rate of Interest (R) = 3% = 3/100 = 0.03
Time (T) = 2 years
⇒ Simple interest = P × R × T
Substitute the value of P, R, and T in the above formula,
⇒ Simple interest = 140 × 0.03 × 2
⇒ Simple interest = $8.4
Therefore, the amount of interest would be $8.4 Charis received at the end of two years.
