Answer:
$2,875
Step-by-step explanation:
Interest = Principal x rate x time
Interest = $2500 x 0.03 x 5
Interest = $375
Original value + interest = Total amount
$2,500 + $375 = $2,875
coffee loses 12% of its weight when roasted. How much fresh coffee do you need to obtain 14 2/25 lb of roasted coffee
16 fresh coffee are needed to obtain 14 2/25 lb of roasted coffee.
How to calculate the number of fresh coffee needed ?Coffee loses 12% of it's weight when it is roasted
The number of fresh coffee that is needed to obtain 14 2/25 lb of roasted coffee can be calculated as follows
let y represent the number of fresh coffee needed
100%-12%
= 88%
= 88/100
= 0.88
14 2/25
= 352/25
= 14.08
The number of fresh coffee can be calculated as follows
0.88y= 14.08
y= 14.08/0.88
y= 16
Hence to obtain 14 2/25 lb of roasted coffee, 16 fresh coffee is required.

how do i solve this
We are basically asked to perform the product of expressions that contain complex numbers a s roots of polynomials. So it is essential to identify the complex root in order to facilitate our products that otherwise could be really time consuming.
First product:
(x + 3 + 5i) (x + 3 - 5i) we are going to write as: ((x +3) +5i) ((x+3) - 5i). So this is going to be interpreted as a difference of squares (a + b) ( a - b) = a^2 - b^2:
((x +3) +5i) ((x+3) - 5i) = (x+3)^2 - (5i)^2 = (x+3)^2 - (-25) = (x+3)^2 + 25
We are using the fact that (i)^2 = -1 to convert - 25 (i)^2 = + 25
Now we solve the square of the binomial (x+3) , that is:
(x+ 3)^2 = x^2 + 6x + 9
Now this combined with + 25 gives: x^2 + 6x + 34 This is one of the options in blue background shown at the tops (the fourth one starting from the left)
Second product:
(x - 4i) (x + 4i) which is an easirer product than the one above because we can solve it just using difference of squares: (a - b) (a + b) = a^2 - b^2:
(x - 4i) (x + 4i) = x^2 - (4i)^2 = x^2 - 16 (i)^2 = x^2 +16
This is the second expression in blue background from left to right.
Third product:
(x - 6 + i) (x - 6 - i) for which we apply the same technique as in the first product we solve above:
(x - 6 + i) (x - 6 - i) = ((x - 6) + i) ((x - 6) - i) = (x-6)^2 - (i)^2 = (x-6)^2 - (-1) = (x-6)^2 + 1 = x^2 - 12 x + 36 + 1 = x^2 - 12 x + 37 which is the very first expression in blue background in the image you uploaded.

The boxplot below shows salaries for Construction workers and Teachers.ConstructionTeacher20254530 35 40Salary (thousands of S)50If a person is making the median salary for a construction worker, they are making more than what percentage ofTeachers?They are making more than% of Teachers.Check Answer
It is known that that the median divides the range into half.
And the first and third quartiles are the landmark for 25% and 75% of the data values.
Therefore, a dot plot is divided into 4 parts, each of ehich represents 25% of the population.
In the given dot plot diagram, it is observed that the mean of the construction worker's salary, coincide with the upper quartile of the salary., at $45,000
It means that 50% population of construction workers is getting at most $45,000 while 75% population of teachers is getting at most $45,000.
So if a construction worker is making the median salary i.e. $45,000, so he/she will be making more than 75% of the teachers.

The equation is y=5x+16.
How to form the required equation?The formula y=mx+b is expressed in slope-intercept form. We are aware of the slope (m) as well as a point (-2,6). We now require the y-intercept (b).We need to enter the information we are aware of in order to solve the y-intercept (b).Y = 6, M = 5, and X = -2 are known values. The equation must be like this: 6=5(-2)+bContinuing, 5(-2) is just 5 times -2, or -10. The new formula is 6=-10+b.Since we must repeat this process for both sides, we must add 10 to the right side to cancel it out and 10 to the left to obtain b. 6+10=-10+10+bB must therefore be 16 because of this.The last step is to construct the equation, where all that is required is to correct the values of m and b in the slope-intercept equation y=mx+b. We know that m is 5 and b is 16.y - 6 = 5(x - (-2)) y=5x+16Therefore, y=5x+16 is the solution.To learn more about equations, refer

1. The least number of hours that.Kee can work is 7 hours.
2. The maximum number of miles that Julie will drive will be 272 miles.
How to illustrate the information?1. Lee makes $64 per hour and he wants to make no less than $400 each hours for the trip. The number of hours will be:
Let the number of hours = h
64h >= 400
Divide
h >= 400/64
h >= 6.25
The least hour should be 7 hours.
2. The maximum number of miles that Julie will drive will be:
44(3) + 0.25m = 200
m = number of miles
132 + 0.25m = 200
0.25m = 200 - 132

) Let us assume that the interest was compounded annually. The formula for calculating compound interest is expressed as
A = P(1 + r/n)^nt
where
A is the amount after t years
P is the principal or initial amount invested
r is the interest rate
n is the number of compounding periods in a year
t is the number of years
From the information given,
P = 130
r = 4% = 4/100 = 0.04
n = 1 because it was compounded once in a year
t = 10
By substituting the values into the formula, we have
A = 130(1 + 0.04/1)^1 * 10
A = 130(1.04)^10
A = 192.43

Line segments JK and JL in the xy-coordinate plane both have a common endpoint /(-4, 11) andmidpoints at M, (2,16) and M, (-3, 5), respectively.What is the distance between M, and M.? Round to the nearest tenth
SOLUTION
From the question, since the coordinates of the mid-points JK and JL has been given as M (2,16) and M, (-3, 5), respectively.
To find the distance between these two mid-points, we simply use the distance formula to do that.
The distance formula is given as
[tex]\begin{gathered} d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\ where\text{ d is the distance } \end{gathered}[/tex]Applying these to the points M (2,16) and M, (-3, 5), we have
[tex]\begin{gathered} d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\ d=\sqrt{(-3-2)^2+(5-16)^2} \\ d=\sqrt{(-5)^2+(-11)^2} \\ d=\sqrt{25+121} \\ d=\sqrt{146} \\ d=12.083045 \\ d=12.1\text{ units } \end{gathered}[/tex]Hence the answer is 12.1 units

A function by definition is a process that takes a collection of inputs and produces a corresponding collection of outputs in such a way that the process produces one and only one output value for any single input value.
