2. ALMN and APMN are shown below. What additional information is necessary to prove
ALMN = APMN by HL?
Help please!!!
Answer:
The additional information necessary is option;
D. [tex]\overline {MN}[/tex] ⊥ [tex]\overline {LP}[/tex]
Step-by-step explanation:
From the given figure, we have;
Given that ML ≅ MP,
The Hypotenuse Leg HL theorem of congruency is used to prove that a given number of right triangles based on the lengths of their hypotenuse and one of the legs. It states that two or more right triangles are congruent if they have equal lengths of both their corresponding hypotenuse side and one leg
To prove that ΔLMN and ΔPMN are congruent by HL, we will also be required to prove that ΔLMN and ΔPMN are right triangles
For ΔLMN and ΔPMN to be right triangles, the angles, ∠LNM and ∠PNM should be right angles = 90°
With ∠LNM = ∠PNM = 90°, then, line [tex]\overline {MN}[/tex] is perpendicular to line [tex]\overline {LP}[/tex] or [tex]\overline {MN}[/tex] ⊥ [tex]\overline {LP}[/tex]
Therefore, the additional information necessary to prove that ΔLMN ≅ ΔPMN by HL is [tex]\overline {MN}[/tex] ⊥ [tex]\overline {LP}[/tex].
A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line labeled A joins the ordered pair 2, 6 with the ordered pair 5, 0. Another straight line labeled B joins the ordered pair 0, 2 with the ordered pair 6, 6.
Part A: How many solutions does the pair of equations for lines A and B have? Explain your answer. (5 points)
Part B: What is the solution to the equations of lines A and B? Explain your answer. (5 points)
Answer:
A. one B. (3, 4)
Step-by-step explanation:
1. A good graph can answer both parts (see attached image).
2. Write equations for the two lines and find a simultaneous solution.
Line A: Slope from (2, 6) to (5, 0) is [tex]m=\frac{6-0}{2-5}=\frac{6}{-3}=-2[/tex]
Using point-slope form [tex]y-y_1=m(x-x_1)[/tex]
[tex]y-6=-2(x-2)\\y-6=-2x+4\\y=-2x+10[/tex]
Line B: Slopt from (6, 6) to (0, 2) is [tex]m=\frac{6-2}{6-0}=\frac{2}{3}[/tex]
Using point-slope form, the equation for Line B is
[tex]y-2=\frac{2}{3}(x-0)\\y=\frac{2}{3}x+2[/tex]
To find the simultaneous solution, set the y's equal.
[tex]-2x+10=\frac{2}{3}x+2\\-6x+30=2x+6\\-8x=-24\\x=3[/tex]
Find y using either equation to get y = 4.

Answer:
EF = 68°
Step-by-step explanation:
If 2 chords of a circle are congruent then the corresponding arcs are congruent.
The central angle FDG is equal in measure to the arc that subtends it
arc FG = 68°
Given EF ≡ FG , then
arc EF ≡ arc FG, so
arc EF = 68°
Penny is going to fly her plane to her sister's house, which is 544.32 miles away. Penny's airplane flies at an average speed of 672 miles per hour. How long does it take Penny to fly to her sister's house?
Answer:
0.81 hour
Step-by-step explanation:
Given data
Distance= 544.32 miles
Speed= 672 miles per hour.
We know that
Speed= distance/time
Substitute
672= 544.32/time
cross multiply
time*672= 544.32
time= 544.32/672
time= 0.81 hour
Marcos sells snow cones in the summer. He uses a cone with a radius of 1.5 inches and a height of 5 inches. If he fills the snow cone to the rim with ice before pouring on the syrup. About how much ice will it take to fill the cone?
Answer: [tex]11.78\ in.^3[/tex]
Step-by-step explanation:
Given
Radius of cone [tex]r=1.5\ in.[/tex]
Height of cone [tex]h=5\ in.[/tex]
Ice required to fill the cone=Volume of cone
The volume of a cone is
[tex]V=\dfrac{1}{3}\pi r^2h[/tex]
Put values
[tex]\Rightarrow V=\dfrac{1}{3}\times \dfrac{22}{7}\times 1.5^2\times 5=11.78\ in.^3[/tex]

Isaac has a points card for a movie theater. He receives 45 rewards points just for signing up. He earns 11.5 points for each visit to the movie theater. He needs 160 points for a free movie ticket.
Answer: 10 visit
Step-by-step explanation:
Given
45 Points earned by signing up
11.5 points earned for each visit to the theatre
160 points are needed for a movie ticket
Suppose, after x visit he gets enough points to buy a movie ticket
[tex]\therefore 160=45+11.5x\\\Rightarrow 115=11.5x\\\Rightarrow x=10[/tex]
So, after 10th visit, he earns a movie ticket

An urban planner wants to create a city block. The city block will be 50 feet by 75 feet. What will the dimensions of his scale drawing be if the drawing has a scale factor of 1 cm = 12.5 ft?
Answer:
The dimensions of his scale drawing = 4 cm by 6 cm
Step-by-step explanation:
An urban planner wants to create a city block. The city block will be 50 feet by 75 feet. What will the dimensions of his scale drawing be if the drawing has a scale factor of 1 cm = 12.5 ft?
From the above question
12.5 ft = 1 cm
Hence
For 50 feet
12.5 feet = 1 cm
50 feet = x
Cross Multiply
12.5 × x = 50
x = 50/12.5
x = 4 cm
For 75 feet
12.5 feet = 1 cm
75 feet = x
Cross Multiply
12.5 × x = 75
x = 75/12.5
x = 6 cm
The dimensions of his scale drawing = 4 cm by 6 cm

Answer:
D
Step-by-step explanation:
substitute t=-3 in the equation
3(-3) squared +5(-3)+6=18
Step-by-step explanation:
According to the question , value of t = (-3) . So on directly putting t = (-3) in expression we have ,
[tex]\tt \to 3t^2 +5t+6 \\\\\tt\to 3(-3)^2+5(-3)+6 \\\\\tt\to (3)(9)-15 +6 \\\\\tt\to 27 - 15 +6 \\\\\tt\to \boxed{\orange{\tt 18 }}[/tex]
I am confused. I believe it is 5(x^2+2)=45
Here is the problem: 5 times the square of a number and 2 is 45.
Answer:
Step-by-step explanation:
We must follow order of operations rules here.
Let the number be x. Then 5x^2 + 2 = 45. No parentheses needed here.
Then 5x^2 = 45, and x = ±9
In order to run a roller coaster at the fair more then 27 people need to ride. If 12 people were in line,which number sentence would show how many more people would need to be in line to ride the roller coaster a x+12<27 b x+ 12 >27 c 27-12>x d 12-x>27
Answer:

visitors spend 1/3 of their time waiting in line for rides. Of the santos family spends 53/4 hours at the park how long do they wait in line
Answer: 1 11/12 hours
Step-by-step explanation:
Since visitors spend 1/3 of their time waiting in line for rides and the Santos family spends 5¾hours at the park.
The tune spent waiting in line will be calculated by multiplying ⅓ by 5¾. This will be:
= ⅓ × 5¾
= ⅓ × 23/4
= 23/12
= 1 11/12 hours
Therefore, they'll wait in the park for 1 11/12 hours
