In trapezoid MNPQ shown below, MN QP,. 108 m M. ∠ = ,. 4 15 m P x. ∠ = - , and. 3 21 m Q x. ∠ = + . Explain why m N. ∠ must be 127
Answer:
The answer is below
Step-by-step explanation:
A trapezoid is a quadrilateral (has four sides and four angles) with a pair of opposite parallel sides. The pair of opposite parallel side is known as the base. Also, the angles on the same leg of a trapezoid (adjacent angles) are supplementary (add up to 180°).
In trapezoid MNPQ:
∠M + ∠Q = 180° (angles on the same leg are supplementary)
108 + (3x + 21) = 180
3x + 129 = 180
3x = 51
x = 17
Also:
∠N + ∠P = 180° (angles on the same leg are supplementary)
∠N + (4x - 15) = 180
∠N = 180 - (4x - 15)
∠N = 180 - 4x + 15
∠N = 195 - 4x
substitute x = 17°:
∠N = 195 - 4(17)
∠N = 127°

Step-by-step explanation:
The f^-1 notation indicates you need to find the inverse of the function
y=2x+1
x=2y+1
Exchange the x & y variables. Note this is what accomplishes that reflection across the line y = x
7=2y+1
-2y=1-7
-2y=-6
Divide both side of the equation by -2
negative divide negative is positive so
y=3

5. A joint of meat weighs 3.5 kg when frozen. It loses 8% of its weight
when it is thawed. Find the mass of the joint when thawed. *
Answer:
The mass of the meat when thawed is 7.72 kg (0.28 kg is lost)
Step-by-step explanation:
From the question, we are told that the weight loss amount is 8% of its initial weight
The mass lost here when thawed will be;
8/100 * 3.5 = 0.28 kg
So the mass of the joint will be;
8-0.28 = 7.72 kg

If y ∝ [tex]\frac{1}{x}[/tex] and y = 4 when x = 2.5, find :
(a) y when x = 20
(b) x when y = 5
Answer:
Step-by-step explanation:
Y = k1/x
4 = k 1/2.5
2.5 x 4 = k
10 = k
Now using this equation we will find the other answers
A) find y when x = 20
Y = k 1/x
Putting values
= 10(1/20) = 1/2 = 0.5
B) find x when y = 5
Y = k 1/x
Putting values
5 = 10 1/x
5x = 10
x = 10/5 = 2
Directions: Solve for x. Round your answer to the nearest tenth.

Firefighters used a ladder 50 feet high to reach a window that was 30 feet above the ground. From the same point on the ground, the ladder is turned to across the street to reach a window that was 40 feet high.
Select all the true statements.
The width of the street, BM, is 70 feet.
The ground distance of the ladder from building B is 30 feet.
The ground distance of the ladder from building M is 30 feet.
The width of the street, BM, is 122 feet.
The length KL is 50 feet.
Answer:
First since 2 of the options ask for the width of BM lets solve for it using the Pythagorean theorem for both sides of point L:
a² + b² = c²
30² + b² = 50²
b² = 50² - 30²
b² = 1600
b = 40 Line BL = 40 ft
Since the ladder is 50 feet it is the same length on the other side as well
a² + b² = c²
40² + b² = 50²
b² = 50² - 40²
b² = 900
b = 30 line LM is 30 ft
SO line lm + line bl = 30 + 40 = 70 ft
A is true because ^
B isn't true because as we solved for earlier, BL is 40
C is true because line LM is in fact 30 ft as we solved for
D is not true because as we said earlier BM is 70
E is true because the same ladder was used on both sides of the street
Step-by-step explanation:
The width of the street, BM, is 70 feet. The ground distance of the ladder from building M is 30 feet. The length of KL is 50 feet.
What is Pythagoras's theorem?Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.
First, because two of the possibilities require the width of BM, let us solve for it using the Pythagorean theorem for both sides of point L.:
a² + b² = c²
30² + b² = 50²
b² = 50² - 30²
b² = 1600
b = 40
So, Line BL = 40 ft
So because the ladder is 50 feet long, it is also the same length on the other side.
a² + b² = c²
40² + b² = 50²
b² = 50² - 40²
b² = 900
b = 30
So, line LM is 30 ft
So line lm + line bl = 30 + 40 = 70 ft
Hence, the true statements are options (A), (C), and (E).

Which function describes this table of values? х у 10 8 5 4 0 0 -5 -4 y = 2 y= y = x - 2 y=-3
Answer:
y=4/5x
Step-by-step explanation:
If you multiply the x value of 10, substitute it into the equation. Using the equation y=4/5x, you will get the y value of 8.
When you substitute the x value of 5 into the equation. You will get 4.
You do this for the rest of the x values and will get the correct y values.

Answer:
Please check the explanation.
Step-by-step explanation:
From the given diagram, we can observe that r and s are the two parallel lines intersected by the two transversal lines.
Therefore, the pairs of alternating interior angles formed by the two transversal lines are:
∠1 & ∠5 ∠2 & ∠4∠2 & ∠7 ∠3 & ∠6We know that alternating interior angles formed by a transversal line are congruent.
Thus,
∠1 = ∠5 ∠2 = ∠4∠2 = ∠7 ∠3 = ∠6Part a)
Given
m∠1 = 3x + 42
m∠5 = 8x - 8
As
∠1 = ∠5
So
3x + 42 = 8x - 8
flipe the equation
8x - 8 = 3x + 42
subtract 3x from both sides
8x - 8 - 3x = 3x + 42 - 3x
5x - 8 = 42
add 8 to both sides
5x - 8 + 8 = 42 + 8
5x = 50
divide both sides by 5
5x/5 = 50/5
x = 10.0000 (Rounded to four decimal places)
Thus, the value of x = 10.0000 (Rounded to four decimal places)
Part b)
Given
m∠6 = 12°
It is clear that angles ∠6 and angle ∠7 lie on a straight line.
Thus,
The sum of ∠6 and ∠7 is 180°.
∠6 + ∠7 = 180°
substituting m ∠ 6 = 12° in ∠6 + ∠7 = 180°
12° + ∠7 = 180°
subtract 12 from both sides
12° + ∠7 - 12° = 180° - 12°
∠7 = 168°
Thus, measure of angle ∠7 = 168°.
We already know that alternating interior angles formed by a transversal line are congruent.
∠7 and ∠2 are alternating interior angles.
Thus,
∠2 = ∠7
As ∠7 = 168°.
Therefore,
∠2 = 168°
Hence, we conclude that
∠2 = 168°

D) About 40 miles
Step-by-step explanation:
Using the Pythagorean theorem, you caculate c=√ a^2 + b^2
Oceanfront to Landview is 5(5) units = 25
Landview to Seaside is 6(5) units = 30
25^2 = 625
30^2 = 900
√625 + 900 = 39.0512....
Basically it’s 40 miles
Answer:
The answer is D, about 40 miles.
Step-by-step explanation:
Use the pythagorean theorem.
Distance between Seaside & Landview: 6
Distance between Landview & Oceanfront: 5
6^2 times 5^2 = [tex]\sqrt{61}[/tex]
[tex]\sqrt{61}[/tex] times 5 = 39.05124838
39.05124838 ≈ 40
