Answer:
13
Step-by-step explanation:
69 total planks divided by 5 for each bookshelf.
That would be 69÷5=13.8
Seeing as you can't make .8 of a shelf, those planks would just be extra.

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

Find the unknown sizes of angles in the following figure (I need step by step explanation and i might give brainliest):
Answer:
x = 54° , y = 29°
Step-by-step explanation:
The sum of the 3 angles in Δ ABC = 180° then
x = 180° - (72 + 54)° = 180° - 126° = 54°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of Δ CQR , then
y + 25° = x
y + 25° = 54° ( subtract 25° from both sides )
y = 29°
Answer:
x = 54
y = 29
Step-by-step explanation:
First, find the magnitude of x. To do this, add the angles inside triangle ABC, which means to add 72 + 54 + x which is equal to 180 because of the rule, the sum of the interior angles of a triangle is 180. So, when the equation is simplified, you get the answer as x = 54. Then, find the magnitude of y. The magnitude of an angle drawn around a point on a straight line is always 360, and the magnitude of the same point, but only on one side of the straight line is always 180. So, we can say that the unnamed angle in the triangle CQR is 180-x, which means 180-54 because we got x as 54 earlier. Therefore, the magnitude of the unnamed angle is 126. Now, apply the same rule we used before, the sum of the interior angles of a triangle is 180, to the triangle QCR. 25 + 126 + y = 180. When this is simplified, 29 is obtained.
To find x,
72 + 54 + x = 180 (the sum of the interior angles of a triangle is 180)
126 + x = 180
126 + x - 126 = 180 - 126
x = 54
To find y,
25 + 126 + y = 180
151 + y = 180
151 + y - 151 = 180 - 151
y = 29

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

Applying angle pair relationships
Answer:
m∠2 = 75°
m∠1 = 105°
Step-by-step explanation:
1. First, we should recognize that the angle that's 75° and ∠2 are alternate interior angles, formed on the interior of the opposite sides of the transversal. Alternate interior angles are congruent, so m∠2 = 75°.
2. Next, ∠2 and ∠1 are a linear pair, meaning their angle measures add up to 180°. Considering that m∠2 is 75 degrees, we just have to subtract 75 from 180, and we get the measure of ∠1.
[tex]180-75[/tex] [tex]105[/tex]Therefore, m∠1 = 105°.

Solve the equation.
b^2 = 48
Answer:
b=6.92820323
Step-by-step explanation:
To find b, you would do the opposite from ^2 which is the square root. So the square root of 48. That is 6.92820323
Answer:
b ≈ 6.928 or 4√3
Step-by-step explanation:
b² = 48. To find b, we need to square root both sides (we are doing the opposite of squaring):
b = √48 = 4√3 or ≈ 6.928

- 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)
