If n ∥ m, which of the following statements are true? Select all that apply.
Answer:
B. m<3 = 100°
C. m<2 + m<4 = 80°
Step-by-step explanation:
Given that n is parallel to m, the following are the measure of each numbered angles:
m<1 = 60° (vertical angles are congruent)
m<2 = 20° (corresponding angles are congruent)
m<3 = 180 - (m<CAB + m<1) (sum of ∆)
m<3 = 180 - (20° + 60°)
m<3 = 100°
m<4 = 60° (corresponding angles are congruent)
Therefore, the following statements are TRUE:
B. m<3 = 100°
C. m<2 + m<4 = 80°
geometry of straight lines
Step-by-step explanation:
In geometry, the notion of line or straight line was introduced by ancient mathematicians to represent straight objects with negligible width and depth. Lines are an idealization of such objects, which are often described in terms of two points or referred to using a single letter.
Types of Lines:Vertical lines: are straight up and down and perpendicular to horizontal lines.Horizontal lines: are straight up and down and perpendicular to vertical lines.Diagonal lines: are lines that straight in any direction except vertical or horizontal.The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept. If you know two points that a line passes through, this page will show you how to find the equation of the line.

La profesora repartió témperas del mismo tamaño entre los chicos. Mariana usó 3/5 de su pote y Juan 3/4 del suyo. ¿Quién usó mayor cantidad y por qué? Representa con dibujos los potes y lo que se usó
Answer:
Juan uso mayor cantidad de témpera.
Step-by-step explanation:
Para comparar fracciones que tienen distintos denominadores, como en este caso, es conveniente encontrar fracciones equivalente a las fracciones dadas, donde ambas tengan el mismo denominador. Dos fracciones son fracciones equivalentes cuando representan la misma parte de la unidad.
En este caso, para comparar las fracciones 3/5 y 3/4, obtienes que el mínimo común múltiplo entre los denominadores que es 20 (el denominador común se puede obtener multiplicando ambos denominadores o calculando el m.c.m) y amplificas cada una de las fracciones para que tengan el mismo denominador.
Entonces:
[tex]\frac{3}{5} =\frac{3*4}{5*4} =\frac{12}{20}[/tex]
[tex]\frac{3}{4} =\frac{3*5}{4*5} =\frac{15}{20}[/tex]
Cuando dos o más fracciones tienen igual denominador, es mayor la que tiene mayor numerador. Entonces en este caso podes observar 15/20 es mayor. Como 3/4 es una fracción equivalente a 15/20, entonces 3/3 es una fracción mayor. Por lo que es posible decir que Juan uso mayor cantidad de témpera.
Esto también se puede observar en la representación de la imagen adjunta, donde se divide en 1/4 y 1/5 y se encuentra pintado la cantidad usada por Juan y Mariana. En ese caso se puede ver que el área pintada es mayor en el caso de 3/4, la cantidad usada por Juan.

Write the equation of the line in slope intercept form that passes through the two points: (1,-6) and (-3,2)
Please explain so I can understand this
Answer:
y = -2x - 4
Step-by-step explanation:
Formula is y = mx + b where m is the slope and b is the y-intercept
(1, -6) (-3, 2)
[tex]\frac{-6-2}{1-(-3)}=\frac{-8}{4} =-2[/tex]
The slope is -2
y = -2x + b
So let's find b, insert 2 for y and -3 for x to find b
2 = -2(-3) + b
2 = 6 + b
Subtract 6 from both sides to get b alone
-4 = b
We found what b equals (the y-intercept), which is -4
So, the equation is y = -2x - 4

A pitcher ok a baseball team is practicing his fast ball trying to ensure he hits the strike zone. He consistently releases the ball 3.4 feet high while he is pitching. The pitcher must aim for the ball to hit the ground approximately 58.8 feet from the pitcher's mound in order to stay in the strike zone. At what angle of depression, to the tenth of a degree, must he release the ball
Answer:
3.3°
Step-by-step explanation:
The set up of the question will give a right angled triangle where the height covered by the bal is the opposite side.
The length at which the pitcher hit the ground is the hypotenuse.
Given
Opposite side = 3.4m
Hypotenuse = 58.8m
Required
Angle of depression
Using SOH CAH TOA trigonometry identity
According to SOH,
Sin(theta) = opposite/hypotenuse
Sin(theta) = 3.4/58.8
Sin(theta) =0.05782
theta = sin^-1(0.05782)
theta = 3.32°
Hence the angle of depression that he must release the ball to nearest tenth is 3.3°

Answer:
x = 44
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
x + 20 + 2x - 40 + 2x - 20 = 180, that is

Answer:
D
Step-by-step explanation:
The perpendicular equation can be found by getting the reciprocal of the slope then multiplying it by -1. The slope is the "m" value of y=mx+b; in this case, the slope is [tex]\frac{2}{5}[/tex].
To find out if it is C or D, you plug in the x value given in the equation (2) and see if it equals the y value given in the equation (-2). C is incorrect, which means that D is correct.

For a craft each student will need five rubber bands.There.There are eight students.Rubber bands come in bags of nine. How many will be needed?How many rubber bands will be left over?
Answer:
40 rubber bands are needed
5 rubber bands will be left from 5 bags of of rubber band
Step-by-step explanation:
Each student will need five rubber bands.
There are eight students
Total rubber bands needed = rubber bands per student × number of students
= 5 × 8
= 40
Total rubber bands needed = 40
Rubber bands come in bags of nine.
Number of bags needed = Total rubber bands needed / number of rubber bands in each bag
= 40 / 9
= 4.44 bags
It is impossible to get decimal number of rubber bands bag, so, the next whole number after 4 is 5
5 rubber bands bags will be bought which = 5 × 9
= 45 rubber bands
Only 40 rubber bands are needed
Left over rubber bands = 45 - 40
= 5 rubber bands

Ericka observed the total variation in the water level over 6.2 years to be −13.64 mm. She compared this to the average annual trend, which shows the water level rising 1.8 mm/year. Remember, she used 6.2 years as her time period. What is the difference between how much average water levels rose and how much the water level fell in the part of the river she observed?
Answer:
3.96mm/year
Step-by-step explanation:
Given that :
Given that:
Observed variation in water level over 6.2 years = - 13.64mm
Average annual trend shows rise in water level at 1.8 mm / year
difference between how much average water levels rose and how much the water level fell in the part of the river she observed?
Average Yearly observed variation :
Observed variation / number of years
-13.64mm / 6.2 years
= - 2.16 mm
Hence, observed yearly fall = - 2.16 mm
Yearly rise = 1.8mm / year
Difference :
( 1.8 mm/year) - (-2.16mm / year)
= (1.8 + 2.16) mm/year
= 3.96 mm/year
Answer:
24.8 millimeters

Dee spends $0.25, $0.30, $0.10 and $0.04.
How much $ does she spend in all?
By adding all the money she spend we get $0.69
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that Dee spends $0.25, $0.30, $0.10 and $0.04.
We need to find the money she spend in all.
Therefore, we have to add all the expenditure
0.25 + 0.30 + 0.10 + 0.04 = 0.69
The total money she spend could be 0.69.

.MARY WAS TOLD TO RUN AROUND THE TRACK 5 TIMES BY HER COACH. ONCE AROUND THE TRACK IS 5/6 OF A MILE. MARY WAS ONLY ABLE TO RUN AROUND THE TRACK 4 1/3 TIMES. HOW MANY MILES TOTAL DID MARY RUN?
Answer:
3.61 miles
Step-by-step explanation:
Given that:
Length of track = 5/6 of a mile
Number times Mary was able to run around the track = 4 1/3 times
Total miles ran by Mary :
(Equivalent mile of the track * number of times Mary ran around the track)
5/6 of a mile * 4 1/3 times
5/6 * 13/3
= 65 / 18
= 3.611111 miles
Hence, total Number of miles ran by Mary is 3.61 miles

Use always, sometimes or never to make a true statement:
Intersecting lines are _____________ coplanar.
Two planes _____________ intersect in exactly one point.
Three points are _____________ coplanar.
A plane containing two points of a line _____________ contains the entire line.
Four points are _____________ coplanar.
Two lines _____________ meet in more than one point.
Two skew lines are __________ coplanar.
Line TQ and Line QT and are _________ the same line.
Answer:
1. Intersecting lines are always coplanar
2. Two planes never intersect in exactly one point
3. Three points are always coplanar
4. A plane containing two points of a line always contains the entire line
5. Four points are sometimes coplanar
6. Two lines never meet in more than one point.
7. Two skew lines are never coplanar
8. Line TQ and Line QT are always the same line.
Step-by-step explanation:
Note: Coplanar means "In the same plane"
1. Each line exist in many planes. But different lines must share at least one plane for them to intersect. That is why intersecting lines are always coplanar.
2. Two planes never intersect at exactly one point because only lines intersect at a point. Planes can only intersect along a line.
3.Three points are always coplanar because in geometry, a group of points are coplanar because there is a geometric plane that they all lie on.
4. A plane containing two points of a line always contains the entire line. Yes
5. Four points are only sometimes coplanar because there is a probability that they may all not lie on the same plane
6. Two lines never meet in more than one point because lines are basically straight and cannot bend over to intersect at another point
7. Two skew lines are never coplanar because skews lines are lines that do not intersect and are never parallel.
8. Line TQ and Line QT are always the same line because a line is straight and extends from one point to the other. So, if a line is labelled TQ calling it QT means the same thing
