if MN=NQ and MQ=QR=RP, calculate for x
Answer:
C. 18°Step-by-step explanation:
Refer to attached diagramGiven MN = NQ MQ = QR = RPNMR = 3xQMR = xTo findValue of xSolutionMN = NQ ⇒ ∠MRN = ∠QMN = 3x+x = 4xMQ = QR ⇒ ∠MRQ = ∠QMR = xRQP is exterior angle of ΔMQR ⇒
∠RQP = x + x = 2xQR = RP ⇒
∠RPQ = ∠RQP = 2x∠QRN is exterior angle of ΔQRP ⇒
∠QRN = 2x + 2x = 4x∠MRN = ∠QRN - ∠QRM = 4x - x = 3x∠MRN = ∠NMR = 3x ⇒
NR = MQNR = MQ ⇒
∠NQR = ∠QRN = 4xWe now have a straight angle MQP:
∠MQP = ∠MQN + ∠RQN + ∠RQP180° = 4x + 4x + 2x10x = 180°x = 18°Correct choice is C
Two trains, Train A and Train B, weigh a total of 510 tons. Train A is heavier than Train B. The difference of their weights is 484 tons. What is the weight of each train?
Answer:
Train A is 497 tons and Train B is 13 tons
Step-by-step explanation:
Let a represent the weight of Train A, and b represent the weight of Train B
Set up a system of equations:
a + b = 510
a - b = 484
Solve by elimination by multiplying the top equation by -1
-a - b = -510
a - b = 484
Add these together, and solve for b:
-2b = -26
b = 13
Find the weight of Train A by plugging in 13 as b into one of the equations, and solving for a
a + b = 510
a + 13 = 510
a = 497
So, Train A is 497 tons and Train B is 13 tons

Answer:
telephone pole height = 480ft
Step-by-step explanation:
Assume that the shadow that an object casts is proportional to the height of the object. Then one can form the ratio:
[tex](shadow : height)[/tex]
Making the assumption that this ratio is proportional for all objects in this given scenario, then one can say that the ratio of the height of the man and his shadow is equal to the ratio of the height of the telephone pole and its shadow:
(man's height) : (man's shadow) = (pole's height) : ( pole's shadow)
Substitute:
6ft : 4ft 6in = (telephone pole hiehgt) : 30ft
Convert to inches (since it is all in the same unit now, one's doesn't need to write the unit anymore):
72 : 54 = (telephone pole height) : 360
Simplify:
4 : 3 = (telephone pole height) : 360
Now solve, use cross products:
3(telephone pole height) = 1440
Inverse operations,
3(telephone pole height) = 1440
/3 /3
telephone pole height = 480
Which rule describes the translation below? On a coordinate plane, triangle S T U is shifted 3 units down and 5 units to the left to form triangle S prime T prime U prime.
Answer:
(x, y) ⇒ (x - 5, y - 3)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Translation is the movement of a point up, down, left or right. If a point A(x, y) is translated a units left and b units down, the new point is at A(x - a, y - b), while If a point A(x, y) is translated a units right and b units up, the new point is at A(x + a, y + b).
Given that triangle S T U is shifted 3 units down and 5 units to the left to form triangle S prime T prime U prime. The rule that describes this translation is given as:
(x, y) ⇒ (x - 5, y - 3)

There are 50 mobile homes in a trailer park. Each mobile home uses 250 gallons of water each day. Write and solve an equation showing how much water the trailer park uses in one day.
Answer: 12500 gallons
Step-by-step explanation:
Number of mobile homes in a trailer park = 50
Gallons of water used by each mobile home = 250 gallons
The amount of water used by the trailer park uses in one day will be:
= Number of mobile homes in the trailer park × Gallons of water used by each mobile home
= 50 × 250
= 12500 gallons

Diagonal 1 (AC) = 5 + 5 = 10
Diagonal 2 (BD) = 4 + 4 = 8
10 + 8 = 80, 80/2 = 40
Answer: 40 square units
What equation(s) could represent the volume of the cylindrical barrel when completely filled with
water?
Answer:
Volume of cylinder = 1,156.57 cm³
Step-by-step explanation:
Given:
Radius R = 4 cm
Height of cylinder = 23 cm
Find:
Volume of cylinder
Computation:
Volume of cylinder = πr²h
Volume of cylinder = (22/7)(4)²(23)
Volume of cylinder = (22/7)(16)(23)
Volume of cylinder = 1,156.57 cm³

The diameter of a circle is 36 inches. What is the circle's area?
Use 3.14 as pi
Step-by-step explanation:
Given
diameter (d) = 36 inches
Radius (r) = d / 2 = 36 / 2 = 18 inches
Now
Area of the circle
= πr²
= 3.14 * 18²
= 1017.36 inches²

Solve the following equations by using the Quadratic formula and answer the subsequent questions:
x^2 - 6x + 9 = 0
a. Are the roots equal or unequal?
b. Are the roots rational or irrational?
c. Are the roots real or non-real?
(Please explain how you got the answers)
Answer:
Step-by-step explanation:
Note that x^2 - 6x + 9 = 0 can be rewritten as the square of a binomial:
(x - 3)^2
and the roots are found by setting this equal to zero and solving for x:
(x - 3)^2 = 0, or x - 3 = ±0, or x = 3 and x = 3
a) there are two equal roots: {3, 3}
b) the roots {3, 3} are rational
c) the roots {3, 3) are real
If you want to use the quadratic formula, proceed as follows:
1. Identify the coefficients of the quadratic: {1, -6, 9}
2. Find the discriminant b^2 - 4ac: It is (-6)^2 - 4(1)(9) = 36 = 36 = 0
As a general rule, if the discriminant is zero, the quadratic has two equal, real roots. These roots are rational: 3 can be rewritten as 3/1, which is a ratio.

A recipe calls for 13 cup of flour and 25 cup of cinnamon. How many cups of cinnamon are needed for each cup of flour?
Answer:
1.92
Step-by-step explanation:
Given :
Cups of flour = 13
Cups of cinnamon = 25
Number of cinnamon cups needed for each cup of flour :
Number of cinnamon cups / number of cups of flour
25 / 13
= 1.923
Hence, about 1.92 cups of cinnamon is needed per cup of flour

3 5 of the first group are right-handed. 80% of the second group are right-handed. What fraction of the class is right-handed?
Answer:
7/10
Step-by-step explanation:
To make things simple, let's turn 80% into a fraction, 8/10. To get a common denominator let's turn 8/10 into 4/5. Since they are both of equal size, the first group would have 2/5 left-handed people and the second 1/5 left-handed people. Let's imagine that each group has 5 people in it. There would be 10 people in total. There is 1 person for each fifth so we can add now. 4 + 3 = 7 right handed people. To check, 2 + 1 = 3 and 3 + 7 = 10. so 7/10 of the class is right-handed.
Can someone please help me with math.
Answer:
neither positive nor negative
Step-by-step explanation:
In order to identify a type of correlation the points have to form where we can draw a line through the points and most of the points will be near that line drawn.
Because most of the points graphed are scattered we cannot identify if it has a positive or negative correlation

Answer:
area of parallelogram = 21
area of trapezoid = 32
Step-by-step explanation:
Hello There!
The first figure shown is a parallelogram and the following dimensions are given
base = 7mm
height = 3mm
The area of a parallelogram can simply be found by multiplying the base by the height
so Area = 7 * 3
7 * 3 =21 so the area of the parallelogram is 21 square millimeters
The second figure given is a trapezoid and the following dimensions are given
height = 4m
base 1 = 5m
base 2 = 11m
To find the area of a trapezoid we use this formula
[tex]A=\frac{a+b}{2} h[/tex]
where a and b are bases and h = height
given the dimensions all we have to do is plug in the values into the formula
[tex]A=\frac{5+11}{2} 4\\5+11=16\\\frac{16}{2} =8\\8*4=32\\A=32[/tex]
so we can conclude that the area of the trapezoid is 32 square meters
