The coins can be distributed in the following manner -
2 quarters (2 x 25) + 2 dimes (2 x 10) + 1 nickel (5) = $0.75
What is Equation Modelling?
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is Michele who has 5 coins Worth 0.75 in all.
We can distribute the coins in the following manner -
2 quarters (2 x 25) + 2 dimes (2 x 10) + 1 nickel (5) = $0.75
Therefore, the coins can be distributed in the following manner -
2 quarters (2 x 25) + 2 dimes (2 x 10) + 1 nickel (5) = $0.75

(b) It takes 37 pounds of seed to completely plant a 4-acre field. How many pounds of seed are needed per acre?
Answer:
9.25 lbs
Step-by-step explanation:
37 is the amount for 4 acres or 4a:
37 = 4a
Isolate and find a by dividing both sides by 4:
4a = 37
4a ÷ 4 = [tex]\frac{37}{4}[/tex]
a = [tex]\frac{37}{4}[/tex] or 9.25 lbs

- Given: C is the midpoint of AE
C is the midpoint of BD
AE = BD
=
Prove: AC = CD
A midpoint is a point that bisects a line into two equal parts.
Given that C is the midpoint of AE, hence;
AC + CE = AE ........ 1
Similarly, if C is the midpoint of BD, then;
BC + CD = BD................... 2
If AE = BD, then we will equate 1 and 2 to have:
AC + CE = BC + CD
Also since CE = BC, the equation becomes
AC + CE = CE + CD
AC = CD (Proved)

Using the sine ratio in the right triangle
sinC = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{AC}[/tex] = [tex]\frac{5}{13}[/tex] , then
∠ C = [tex]sin^{-1}[/tex] ( [tex]\frac{5}{13}[/tex] ) ≈ 22.6° ( to 1 dec. place )

Find the measure of the angles (S)
Please help out:/
Answer:
Step-by-step explanation:
The triangle’s angles add up to 180°
so 180 - (5x - 2) = the another one interior angle
180 - 5x + 2
182 - 5x
and then 2x + 76 + (182 - 5x) = 180
2x + 76 + 182 - 5x = 180
258 - 3x = 180
78 = 3x
x = 26
so 2x = (26)(2) = 52
5x - 2 = (5)(26) - 2 = 128

The table shows the outputs, y, for different inputs, x:
Input (x) 1 2 3 4
Output (y) 5 5 7 9
Part A: Do the data in this table represent a function? Justify your answer. (3 points)
Part B: Compare the data in the table with the relation f(x) = 2x − 8. Which relation has a greater value when x = 4? (2 points)
Part C: Using the relation in Part B, what is the value of x if f(x) = 34? (5 points)
(10 points)
Answer:
See belowStep-by-step explanation:
Part AAccording to definition of the function, the data in the table is a function. Each input value has own output and no repeat inputs.Part BAt x = 4, y = 9 (table)At x = 4, f(4) = 2*4 - 8 = 8 - 8 = 0The relation in the table has greater value as 9 > 0
