Answer:
x=6
Step-by-step explanation:
The angles are alternate exterior angles, which are equal
19x-4 = 110
Add 4 to each side
19x -4+4 = 110+4
19x = 114
Divide by 19
19x/19 = 114/19
x=6
I think x=6............

Which of the following theorems verifies that XYZ - UWV
A. HL
B. AA
C. LL
D. HA
Given:
The figure of two triangle XYZ and UWV.
To find:
The theorem that is used to verify [tex]\Delta XYZ\sim \Delta UWV[/tex].
Solution:
In triangle XYZ,
[tex]m\angle X+m\angle Y+m\angle Z=180^\circ[/tex] (Angle sum property)
[tex]70^\circ+90^\circ+m\angle Z=180^\circ[/tex]
[tex]160^\circ+m\angle Z=180^\circ[/tex]
[tex]m\angle Z=180^\circ-160^\circ[/tex]
[tex]m\angle Z=20^\circ[/tex]
In triangle XYZ and triangle UWV,
[tex]m\angle Y\cong m\angle W[/tex] (Right angles)
[tex]m\angle Z\cong m\angle V[/tex] (Equal measures)
Two angles of one triangle are congruent to corresponding angles of another triangle. So, the triangles are similar by AA property of similarity.
[tex]\Delta XYZ\sim \Delta UWV[/tex] (AA similarity theorem)
Therefore, the correct option is B.

Answer:
h = 9.6 ft
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
h² + 7.2² = 12² ( h is the height of the building )
h² + 51.84 = 144 ( subtract 51.84 from both sides )
h² = 92.16 ( take the square root of both sides )
h = [tex]\sqrt{92.16}[/tex] = 9.6 ft
in a class of 32 students
Answer:
1.48 m
Step-by-step explanation:
mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
Then the sum for the 14 boys is
[tex]\frac{sum}{14}[/tex] = 1.56 ( multiply both sides by 14 )
sum = 21.84 m
The sum for the class of 32 is
[tex]\frac{sum}{32}[/tex] = 1.515 ( multiply both sides by 32 )
sum = 48.48 m
Thus the sum for the 18 girls is
sum = 48.48 - 21.84 = 26.64 m
Then mean height of girls is
mean = [tex]\frac{26.64}{18}[/tex] = 1.48 m
Charles is cooking enough lentils for lentil barley soup and lentil salad. The soup recipe calls for 3/4 cup of dried lentils. The salad recipe calls for 1 1/ 2 cups of dried lentils. Jon has a 1/8 -cup scoop. How many scoops of dried lentils will Charles need to have enough for the soup and the salad?
Answer:
18 scoops is the correct answer
Step-by-step explanation:
3/4 can also be written as 6/8 (multiply both 3 and 4 by 2)
and 1 1/2 is actually 3/2 which can be written as 12/8 (multiply both 3 and 2 by 4)
thus total lentils required is 6/8 + 12/8 = 18/8 cups.
with scoop size 1/8 cup you'll need 18 scoops .
Answer:
18 1/8 scoops
Step-by-step explanation:
Soup:
6 scoops from a 1/8 cup can make a 3/4 cup
Salad:
4 scoops from a 1/8 cup can make a 1/2 cup
If 1/8 means one portion is divided into eight portions, then 8 scoops from a 1/8 cup can make 1 cup.

Answer:
Uuy
Step-by-step explanation:
-2/3a+6=-14 what is a?
[tex] - \frac{2}{3} a + 6 = - 14[/tex]
[tex](3)( - \frac{2}{3} a + 6) = ( - 14)(3)[/tex]
[tex] - 2a + 18 = - 42[/tex]
[tex] - 2a + 18 - 18 = - 42 - 18[/tex]
[tex] - 2a = - 60[/tex]
[tex] - 2a \div - 2 = - 60 \div - 2[/tex]
[tex]a = 30[/tex]

x1=-7
y1=5
x2= 4
y2= -3
The expression for the distance between two points is
d=√((x_2-x_1)²+(y_2-y_1)²)
substitute
d=√((4-(-7))²+(-3-5)²)
d=√((4+7))²+(-8)²)
d=√(11)²+(-8)²)
d=√121+64
d=√185
d=13.60units
Hence the distance is 13.60units

SOMEONE PLS HELP ME FIND X
Answer:
step one you look at the question until you find the ex cuz it says 125 degrees and 125 degrees 2x
Answer:
x = 50
Step-by-step explanation:
The sum of all entire angles in this, esentially a pentagon, add up to 540
To find x, use the following
540 = 125 + 125 + 90 + 2x + 2x
540 - 125 - 125 -90 = 4x
200 = 4x
200 / 4 = x
50 = x

Answer:
x = 5[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Using the tangent ratio and the exact value
tan60° = [tex]\sqrt{3}[/tex] , then
tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{5}[/tex] = [tex]\sqrt{3}[/tex] ( multiply both sides by 5 to clear the fraction )
x = 5[tex]\sqrt{3}[/tex]

What is the volume of a cone that has a height of 10 feet and a base with a surface area(B) of 9 square feet?
Answer:
30 cubic feet
Step-by-step explanation:
According to the scenario, calculation of the given data are as follows,
Height of cone (h) = 10 feet
Base surface area = π[tex]r^{2}[/tex] = 9 sq. feet
So we can calculate the volume of cone by using following formula,
volume of cone = (1/3)π[tex]r^{2}[/tex]h
By putting the value in the formula, we get
Volume of cone = (1/3) 9 × 10
= 3 × 10
= 30 cubic feet

Given that (1, 0, 1) is a solution to a system of three linear equations, which of the following is true about the system?
The system can be either inconsistent or consistent.
The system can be either independent or dependent.
The system can only be independent and consistent.
The system can only be dependent and inconsistent.
===========================================================
Explanation:
Let's go through the answer choices
A) This isn't possible. Either a system is consistent or inconsistent. It cannot be both at the same time. The term "inconsistent" literally means "not consistent". It's like saying a cup is empty and full at the same time. We can rule out choice A.B) This is similar to choice A and we cannot have a system be both independent and dependent. Either a system is independent or dependent, but not both. Independence means that the two equations are not tied together, while dependent equations are some multiple of each other. We can rule out choice B.C) We'll get back to this laterD) The independence/dependence status is unknown without the actual equations present. However, we know 100% that this system is not inconsistent. This is because the system has at least one solution. Inconsistent systems do not have any solutions at all (eg: parallel lines that never cross). We can rule out choice D because of this.Going back to choice C, again we don't have enough info to determine if the system is independent or dependent, but we at least know it's consistent. Consistent systems have one or more solutions. So part of choice C can be confirmed. It being the only thing left means that it has to be the final answer.
If it were me as the teacher, I'd cross out the "independent" part of choice C and simply say the system is consistent.
Answer:
Above that (1, 0, 1) is a solution to a system of three linear equations, The system can only be independent and consistent. is true about the system.

Hayden is creating triangles using plastic straws cut to various lengths for the sides. Which set of straw lengths can he use to create a scalene triangle?
Answer:
The answer is below
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, acute, scalene, obtuse, right and equilateral triangle.
A scalene triangle is a triangle in which all the three sides of the triangle have different lengths hence, all the angles of the triangle also have different lengths.
Therefore the set of straw lengths that can be used a scalene triangle must have different lengths, for example:
5, 7 , 8
