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.

Answer:
m∠TQS = 137°
m∠RQS = 43°
Step-by-step explanation:
It is given that ∠RQT is a straight angle
That means that this angle is 180° and RQT is a straight line
Therefore m∠TQS + m∠RQS = m∠RQT = 180°
Given
m∠TQS = (6x + 20)° and m∠RQS = (2x + 40)°
adding the two angles together will imply
(6x + 20)° + (2x + 40)° = 180°
=> 6x + 20 + 2x + 4 = 180
=> 6x + 2x + 20 + 4 = 180
=> 8x + 24 = 180
=> 8x = 180 - 24= 156
=> x = 156/8 = 19.5
Substitute for x in the angle expressions
m∠TQS = 6x + 20 = 6(19.5) + 20 = 117 + 20 = 137°
m∠RQS 2x + 4 = 2(19.5) + 4 = 39 + 4 = 43°
(or we could subtract m∠TQS from 180 to get 180 - 137 = 43°)
Check if they add up to 180°
137° + 43° is indeed 180°
Julia owns a food truck that sells tacos and burritos. She only has enough supplies to make 67 tacos or burritos. She sells each taco for $3.75 and each burrito for $6. Julia must sell no less than $330 worth of tacos and burritos each day. If 42 burritos were sold, determine all possible values for the number of tacos that Julia must sell in order to meet the requirements. Your answer should be a comma separated list of values. If there are no possible solutions, submit an empty answer.
Julia must sell 21 tacos to meet the requirement .
Given: Price of each taco = $ 3.75
Price of each burrito = $ 6
Total amount of money she needs to earn = $ 330
Also the number of burritos sold= 42.
So the total amount earned on selling these burritos= 42× 6 = $ 252
And as it is given that total money she needs to earn is $ 330 .
so required money= $ 330- $ 252
=$ 78
Thus the total number of tacos she needs to sell = 78/ price of 1 taco
= 78/ 3.75
= 20.8 ≈ 21
Thus Julia must sell 21 tacos to meet the requirement .

A power function has the formula f(x) = kxⁿ,
A power function is a function that has a single term that is the product of a real number, a coefficient, and a variable raised to a fixed real value. (A coefficient is a value that increases an exponent by a variable.)
A power function has the formula f(x) = kxⁿ, where k and n are both real numbers. You can change the appearance of a power function's graph by changing the values of k and n. As a result, in this graph, n is greater than zero.The Power function produces an integer that has been raised to a particular power. Power is an alternative for the exponent operator in a mathematical equation (^). The Power function only takes two arguments: number and power. Number must be a numeric value that is either a hardcoded constant or a cell reference.Monomial functions:
Linear: y=3x+5
Quadratic: y = x²
Constant: y = 6
Cubic: y = x³+5
Quartic : y = x⁴
Quantic : y = x⁵
Therefore the function with a power function is given by y = k xⁿ

The value of y varies directly with x. If y = 8, when x = 4, what is y when x = 48?
Answer:
96
Step-by-step explanation:
If Y is directly proportional (or in this case varies directly) then whatever you do to one value you do to the other.
So in this case, when Y = 8 and X = 4 that means that Y is double of X (cause 8 is double 4).
So when X = 48 all you need to do is double X which will give you 96.

A hiker walked 15 miles from 8:00 a.m. to noon. He walked an additional 18 miles from 1:00 p.m. to 7:00 p.m.
What is his average rate for the entire walk, in miles per hour?
The average rate for the entire walk of hiker is 3.75 miles per hour by the concept of average speed.
What is average speed?The instantaneous speed is the upper limit of the average speed as the duration of the time interval approaches zero. An object's average speed during a certain period of time is equal to its distance traveled over that period divided by its duration. Speed and velocity are distinct concepts.
The whole distance traveled divided by the total time results in the average rate for the entire walk, expressed in miles per hour.
Given that:
Distance A = 12.8 miles
Distance B = 17.2 miles
Total distance = Distance A + Distance B
Total distance= 12.8 + 17.2
Total distance= 30 miles
Time A = 9:00 a.m. to noon = 3 hours
Time B = 1:00 p.m. to 6:00 p.m. = 5 hours
Total time = Time A + Time B
Total time= 3 + 5
Total time= 8 hours
Average rate = Total distance/Total time
Average rate= 30 miles/8 hours
Average rate= 3.75 miles per hour
Therefore, the average rate for the entire walk of hiker is 3.75 miles per hour.

identify the y-intercept: 6 - 2y = -6
We know that the equation of a line is given by
y = mx + b, where m and b are numbers:
m is the slope of the line and b is the y intercept.
In this case we have the equation:
6 - 2y = - 6
We clear y so we can identify m and b
6 - 2y = -6
6 = -6 + 2y
6 + 6 = 2y
12 = 2y
12/2 = y
6 = y
In this case
y = 6
Then m=0 and b = 6

Given three points of a quadratic function, find the equation of the function: (-1, -3), (0, -4), (2, 6)
A) f(x)=2x^2+2x−4f
B) f(x)=x^2+2x−4f
C) f(x)=x^2+x−4f
D) f(x)=2x^2+x−4f
The quadratic function has an equation of f(x) = 2x²+ x - 4
How to determine the equation of the functionFrom the question, the ordered pairs are given as
(-1, -3), (0, -4), (2, 6)
A quadratic function is represented as
f(x) = ax²+ bx + c
Using the point (0, -4), we have
a(0)²+ b(0) + c = -4
So, we have
c = -4
This gives
f(x) = ax²+ bx - 4
Using the point (-1, -3), we have
a(-1)²+ b(-1) - 4 = -3
So, we have
a - b = 1
Using the point (2, 6), we have
a(2)²+ b(2) - 4 = 6
So, we have
4a+ 2b = 10
So, we have
a - b = 1
This gives
a = b + 1
Substitute a= b + 1 in 4a+ 2b = 10
4(b + 1) + 2b = 10
This gives
4b + 4 + 2b = 10
Evaluate
6b = 6
Divide
b = 1
So, we have
a = 1 + 1
a = 2
So, we have
f(x) = 2x²+ x - 4
Hence, the equation is f(x) = 2x²+ x - 4
