question 11(multiple choice worth 5 points) (02.06 mc) what is the measure of angle x? a pair of parallel lines is cut by a transversal. an exterior angle on the left of the transversal is labeled as 40 degrees. an interior angle on the right of the transversal, which is not vertically opposite to the 40 degree angle, is labeled as x. 40 degrees 80 degrees 130 degrees 140 degrees
The measure of angle x is 140°
For given question,
We are given that a pair of parallel lines is cut by a transversal line .
Let a pair of parallel lines are PQ and RS and the transversal line AB cut the parallel lines PQ and RS.
We are given that an exterior angle on the left side of the transversal line is 40 degrees.
The interior angle on the right side of transversal line is x which is not vertical opposite to exterior angle = 40 degrees
We know that when two lines are parallel and cut by a transversal line then corresponding angles are congruent.
So, angle MNR = 40°
Also, ∠MNR + ∠MNS = 180° ...............(linear pair of angles)
⇒ 40° + x = 180°
⇒ x = 140°
Therefore, the measure of angle x is 140°

A recipe calls for 1/2 cup sugar and 1 cup flour. Complete the table to show how much sugar and flour to use in different numbers of batches of the recipe. sugar (cups) flour (cups) 1/4 늘 1 ml 11 -I 2
Answer:
1/2 = 1
3/4 = 1.5
0.875 = 1 3/4
1 = 2
1.25 = 2 1/2
Step-by-step explanation:
The solution is
Cups of sugar = 1/2 cups , Cups of flour = 1 cup
Cups of sugar = 3/4 cups , Cups of flour = 1 1/2 cups
Cups of sugar = 7/8 cups , Cups of flour = 1 3/4 cups
Cups of sugar = 1 cup , Cups of flour = 2 cups
Cups of sugar = 5/4 cups , Cups of flour = 2 1/2 cups
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of cups of sugar = S
Let the number of cups of flour = F
Now , the equation will be
1/2 cups of sugar will result in = 1 cup of flour
So , the ratio of S : F = 1 : 2
Now ,
3/4 cups of sugar will result in = 2 x 3/4 cups of flour
3/4 cups of sugar will result in = 6/4 cups of flour
3/4 cups of sugar will result in = 3/2 cups of flour
Now ,
S cups of sugar will result in = 1 3/4 cups of flour
S cups of sugar will result in = 7/4 cups of flour
S cups of sugar = ( 1/2 ) ( 7/4 ) cups
S cups of sugar = 7/8 cups
7/8 cups of sugar = 1 3/4 cups of flour
Now ,
1 cup of sugar = 2 x 1 cups of flour
1 cup of sugar will result in = 2 cups of flour
Now ,
S cups of sugar will result in = 2 1/2 cups of flour
S cups of sugar = 5/2 cups of flour
S cups of sugar = ( 1/2 ) x ( 5/2 ) cups
S cups of sugar = 5/4 cups
5/4 cups of sugar = 2 1/2 cups of flour
Hence ,
Cups of sugar = 1/2 cups , Cups of flour = 1 cup
Cups of sugar = 3/4 cups , Cups of flour = 1 1/2 cups
Cups of sugar = 7/8 cups , Cups of flour = 1 3/4 cups
Cups of sugar = 1 cup , Cups of flour = 2 cups
Cups of sugar = 5/4 cups , Cups of flour = 2 1/2 cups

d. 70
The measure of the angle m∠J is 35°.
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located.
Consider the triangle KJL,
The line KM is perpendicular to the line JL and M is the midpoint of the line JL.
Therefore, the angle KMJ will be equal to 90°.
Now, we have the angle KJM is equal to 55°.
We know the sum of all interior angles of a triangle is 180°.
So,
In triangle JKM,
∠JKM + ∠KJM + ∠KMJ = 180°
∠JKM + 55° + 90° = 180°
Subtracting 90° from each side of the equation.
∠JKM + 55° + 90° - 90° = 180° - 90°
∠JKM + 55° = 90°
Subtracting 55° from each side of the equation.
∠JKM + 55° - 55° = 90° - 55°
∠JKM = 35°

If a thumb is a finger, then three gloves and three shoes normally hold thirty-five fingers and toes
The given statement is false because the total number of toes and fingers are 30 and not 35.
How to identify true or false mathematical statements?
We are told that If a thumb is a finger, then three gloves and three shoes normally hold thirty-five fingers and toes.
Now, we know that a glove has space for 5 fingers. This means that three gloves would have a total of; 5 * 3 = 15 fingers
Now, a shoe has space for 5 toes. Thus;
Three shoes would have a total of; 5 * 3 = 15 toes
Thus;
Total fingers and toes = 15 + 15 = 30
Thus, we conclude that the given statement is false because the total number of toes and fingers are 30 and not 35.

Jackie went to the store and bought 2 1/4 pounds of apples at $5 per pound and 9 pounds of pears at $2.35 per pound. If she paid with a $50 bill, how much change did she receive? Hint* USE THE $ SIGN IN YOUR ANSWER. YOUR ANSWER SHOULD HAVE 2 DECIMAL PLACES.
Answer:
$17.60
Step-by-step explanation:
Jackie went to the store and bought 2 1/4 pounds of apples at $5 per pound
1 pounds = $5
2 1/4 pounds = x
x = 2 1/4 × $5
x = 9/4 × $5
x = $45/4
x = $11.25
9 pounds of pears at $2.35 per pound.
1 pound = $2.35
9 pounds = x
x = 9 × $2.35
x = $21.15
Total amount that she spent =
$11.25 + $21.15
= $32.40
If she paid with a $50 bill, how much change did she receive?
The change she received =
$50 - $32.40
= $17.60

Using the given table of an exponential function, determine the growth/decay factor as well as the rate of increase/decrease. Type your answers in as numbers. Example: Growth Factor: 3.5, Rate of Increase: 2.5. (Do not input your rate of increase as a percent.)
Answer:
The growth rate is 0.6
The growth factor is 1.6
Step-by-step explanation:
Generally, the exponential equation can be written as;
y = a(1 + r)^x
Where a is the initial value of 100
r is the growth rate
So let us form equations;
160 = 100(1 + r)^1 •••••(i)
Also;
256 = 100(1 + r)^2 •••••••(ii)
Divide equation ii by i
256/160 = 1 + r
1.6 = 1 + r
r = 1.6-1
r = 0.6

The perimeter of a triangle is the sum of the lengths of its three sides. Here, you're given the perimeter and two of the sides. The third side will be the length that makes up the difference.
P = side 1 + side 2 + side 3
18m³ +2m² -m = (5m³ +3m² -2m) +(5m³ +3m² -2m) + side 3
18m³ +2m² -m = (10m³ +6m² -4m) + side 3 . . . . . collect terms
18m³ +2m² -m - (10m³ +6m² -4m) = side 3 . . . . . subtract (10m³ +6m² -4m)
m³(18 -10) +m²(2 -6) +m(-1 +4) = side 3 . . . . . . . . . group like terms

Answer: second and fourth choices have infinitely many solutions
Step-by-step explanation:
When you combine the like terms in those two equations you end up with an "identity." Both sides of the equation are the same.
x - 1/3(3x) = 0 . 1/3 of 3x is 1x
x - x = 0 any number minus itself is 0
or add x to both sides x-x+x = 0 + x
x = x is an identity. An identity has infinite solutions.
3x + 2 - 1/3(3x) = 2 + 2x
3x + 2 -x = 2 + 2x
2x +2 = 2 + 2x . same thing! Infinite solutions.

Multiply numerator and denominator by 6-2i.
[tex]=\dfrac{5\times (6-2i)}{(6+2i)\times (6-2i)}[/tex]
[tex]=\dfrac{5(6)+5(-2i)}{6^2+(2i)^2}[/tex]
[tex]=\dfrac{30-10i}{36+4i^2}[/tex]
[tex]=\dfrac{30-10i}{36+4(-1)}[/tex] [tex][\because i^2=-1][/tex]
On further simplification, we get
[tex]=\dfrac{30-10i}{36-4}[/tex]
[tex]=\dfrac{30-10i}{32}[/tex]
[tex]=\dfrac{30}{32}-\dfrac{10i}{32}[/tex]
[tex]=\dfrac{15}{16}+(-\dfrac{5}{16})i[/tex]
Therefore, the form a+bi is [tex]\dfrac{15}{16}+(-\dfrac{5}{16})i[/tex], where, [tex]a=\dfrac{15}{16}[/tex] and [tex]b=(-\dfrac{5}{16})[/tex].

Center middle school open the boys basketball team has had the same record every season the team has won a total of 84 games while losing only six games find the constant of a personality of winds to loses
The constant of Proportionality of wins to loses is 12.
Given, The total no. of games won by team is 84 and the team loses 6 games in the season.
When two or more parameters are directly or indirectly proportional to one another, their relationship is expressed as a = kb or a = k/b, where k indicates how the two variables are related. This k is known as the proportionality constant.
So, let a = Total no. of games won by team
and b = no. of games lost by team
So, proportionality constant (k) = Total no. of games won by team(a) / no. of games lost by team(b)
k = 84/6
k = 12.
Hence, the proportionality constant is 12.
