Answer:
m<L = [tex]33.9^{o}[/tex]
Step-by-step explanation:
Triangle JKL is an isosceles triangle, given that <J ≅ <L. An isosceles triangle has two of its angles and sides to be equal.
The exterior angle formed = [tex]67.8^{0}[/tex]
But,
<J + <L = [tex]67.8^{0}[/tex] (the sum of two opposite interior angles is equal to the exterior angle)
Let <J ≅ <L be represented by a, so that;
a + a = [tex]67.8^{0}[/tex]
2a = [tex]67.8^{0}[/tex]
a = [tex]\frac{67.8^{o} }{2}[/tex]
= [tex]33.9^{o}[/tex]
The measure of <L is m<L = [tex]33.9^{o}[/tex] (m<L =
Thus,
m<J ≅ m<L = [tex]33.9^{o}[/tex]

Which explains whether or not Ming has described a proportional relationship, and why?
Ming has described a proportional relationship because the ordered pairs are linear and the line passes through the origin.
Ming has not described a proportional relationship. Although it is a linear relationship, it does not pass through the origin.

Tickets to a football game cost $6 per ticket write and equation that represents this relationship between tickets purchased and total cost . Use t to represent the number of tickets purchased and c to represent the total cost
Given:
Tickets to a football game cost $6 per ticket.
To find:
The equation that represents this relationship between tickets purchased and total cost.
Solution:
Let t represents the number of tickets purchased and c represents the total cost.
Cost of 1 ticket = $6
Cost of t ticket = $6t
Since, c is the total cost oft tickets, therefore the equation for given situation is
[tex]c=6t[/tex]
Therefore, the required equation is [tex]c=6t[/tex].

What is the length of DF? Round to the nearest hundredth.
Answer:
7.06
Step-by-step explanation:
This triangle can be solved a couple of ways. In the end, they amount to the same thing.
1) The area is ...
A = 1/2bh = 1/2(8)(15) = 60 . . . using DG as the base
Using GE as the base, the height (DF) is ...
A = (1/2)(17)(DF)
2(60)/17 = DF = 120/17
DF ≈ 7.06
__
2) Using similar triangles, we can find the ratio of the long side to the hypotenuse as ...
(long side)/(hypotenuse) = DE/GE = DF/DG
DF = DG(DE/GE) = 8(15/17) = 120/17
DF ≈ 7.06
Write a power that has a value greater than 140 and less than 145.
Answer:
[tex]12^{2}[/tex]
Step-by-step explanation:
To find: a power that has a value greater than 140 and less than 145
Solution:
Take [tex]x=12^{2}[/tex]
Here,
[tex]12^{2}=144[/tex] and [tex]140<144<145[/tex]
That is [tex]140<x<145[/tex]
Therefore,
[tex]12^{2}[/tex] has a value greater than 140 and less than 145.
11. A large pine tree was struck by lightning and fell as
shown by the diagram below. Which equation
could be used to find the length of the fallen part of
the tree?
8 ft
13 ft —
A. 82 +132 - X
B. N82+132 -
C. 132 - 82 = X
D. V132 - 82 - *
It forms a right triangle.
To find X you can use the Pythagorean theorem which would be written as x^2 = a^2 + b^2
This can be rewritten as x = sqrt(a^2 + b^2)
Using the dimensions of the tree the answer would be :
B. x = sqrt(8^2 + 13^2)
The equation to find the length of the fallen part of the tree is
[tex]x=\sqrt{8^2+13^2}[/tex]
Right Triangle.
Right triangles is a triangle with one angle is 90 degree.
The side opposite to 90 degree is the hypotenuse.
Pythagorean Theoremthe sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse .
The length of the fallen part of the tree is the hypotenuse
Hypotenuse is 'x'
Base of the triangle is 13 feet and height is 8 ft
Apply Pythagorean theorem to find out the hypotenuse 'x'
[tex]hypotenuse^2= base^2 + height ^2\\x^2=\sqrt{13^2+8^2} \\x=\sqrt{13^2+8^2}[/tex]
the equation to find the length of the fallen part is
[tex]x=\sqrt{8^2+13^2}[/tex]

how many squares would have to be shaded to that 1/6 of the shape is shaded
Answer:
3 squares
Step-by-step explanation:
Firstly, you have to count the number of squares in the shape. As it can been seen from the diagram, there are a total 18 squares (i.e 6 squares on each row × 3 squares on each column).
Secondly you have to find 1/6 of the total number of the squares in the shape. 1/6 of the total number of the square in the shape = 1/6 × 18 = 3 squares
Therefore 3 squares would have to be shaded so that 1/6 of the shape is shaded

A school play sells adult and child tickets. On Friday they sold 55 child tickets and 20 adult tickets for $200. On Saturday they sold 72 child tickets and 36 adult tickets for $306. What is the cost of a child ticket?
Answer:
$2
Step-by-step explanation:
Let, price of individual child ticket is $x, and price of individual adult ticket is $y.
Now, on Friday we can write an equation is 55x+20y=200....(1).
and on Saturday we can write an equation is 72x+36y=306.....(2).
so, Equation 1: 55x+20y=200
Equation 2: 72x+36y=306
now, we are going to solve both equations.
after solving you will find x=2 and y=4.5
Hence, we can say that the cost of child ticket is $2, and the cost of adult ticket is $4.50.
The cost of a child's ticket will be $2.

Let, the price of an individual child ticket is $x, and the price of an individual adult ticket is $y.
Now, on Friday we can write an equation is 55x+20y=200....(1).
On Saturday we can write an equation is 72x+36y=306.....(2).
The first equation is:-
55x+20y=200
The second equation will be written as:-
72x+36y=306
Now, we are going to solve both equations. After solving you will find x=2 and y=4.5
Hence, we can say that the cost of a child ticket is $2, and the cost of an adult ticket is $4.50.

Based on the shading we can tell that the sign is going to always be shaded on the right side. We see the line is dashed (its kinda hard to see) but a dashed line means none of the points on it can be part of the solution. If it was a solid line it would be ≤ and we see it's not so its <
Lincoln High School's basketball team won the regional playoffs scoring a
total of 60 points, not including free throws. The team made a total of 26
baskets; some were 2-point shots, and the rest were 3-point shots. How
many 2-point shots did the team make?
Answer:
y = 8
x = 18
Step-by-step explanation:
(x + y = 26) x2 -1
2x+3y = 60 -2
2x+2y = 52 -1
2x+3y = 60 -2
Subtracting equation 2 from equation 1
= -y = -8
= y = 8
_____________________________________________________
2x+3y = 60
= 2x+3x8 = 60
= 2x+24 = 60
= 2x = 60-24
= 2x = 36
= x = 36/2
= x = 18

Answer:
Percentage increase= 125%
Step-by-step explanation:
Giving the following information:
2018= 200 dogs
2019= 450 dogs
To calculate the percentage increase, we need to use the following formula:
Percentage increase= [(2019 - 2018)/2018]*100
Percentage increase= [(450 - 200)/200]*100
Percentage increase= 125%
