Step-by-step explanation:
Given: AB ≅ BC , AE ≅ FC Prove: m∠AEC=m∠AFC
Answer:
EC/AB = FC/MA
Step-by-step explanation:
We are given AB
≅
BC that means that side AB and side BC are equal also we know that angle opposite to equalt
sides are equal.
Hence, ∠BAE=∠BCE-------(1)
Also ∠AEB=∠CEB.
Now we are given that: ∠ABC = 130°30’ i.e. in degrees it could be given as:
60'=1°
30'=(1/2)°=0.5°
Hence ∠ABC = 130°30’=130+0.5=130.5°
Also we know that sum of all the angles in a triangle is equal to 180°.
Hence,
∠BAE+∠BCE+∠ABC=180°.
2∠BAE+130.5=180 (using equation (1))
2∠BAE=49.5
∠BAE=24.75° (DIVIDE BOTH SIDE BY 2)
Now in triangle ΔBEC we have:
∠BEC=90° , ∠BCE=24.75°
SO,
∠BEC+∠BCE+∠EBC=180°.
Hence, 90+24.75+∠EBC=180
∠EBC=180-(90+24.75)
∠EBC=65.25°
Now we are given AE = 10 in
Also ∠BEA= 90°.
And ∠BAE=24.75°; hence using trignometric identity to find the measure of side BE.
\begin{gathered}\tan 24.75=\dfrac{BE}{AE}=\dfrac{BE}{10}\\\\BE=10\tan 24.75-------(2)\end{gathered}tan24.75=AEBE=10BEBE=10tan24.75−−−−−−−(2)
similarly in right angled triangle ΔBEC we have:
\begin{gathered}\tan 24.75=\dfrac{BE}{EC}\\\\\tan 24.75=\dfrac{BE}{EC}\\\\EC=\dfrac{BE}{\tan 24.75}------(3)\end{gathered}tan24.75=ECBEtan24.75=ECBEEC=tan24.75BE−−−−−−(3)
Hence, using equation (2) in equation (3) we get:
EC=10 \text{in.}EC=10in.
Hence AC=AE+EC=10+10=20 in.
Hence side AC=20 in.

Tony bought 3 tickets to a concert for $78. How much will it cost for 6 tickets to the concert if all tickets have the same unit price? Use the table below to help determine the missing value:
Number of Tickets 3 4 5 6
Cost $78 $104 $130 ?
(3 points)
Select one:
a.
$136
b.
$146
c.
$156
d.
$234
Answer:
c. $156
Step-by-step explanation:
There are two ways to solve this problem. The first is doubling the first cost as 6 is 2(3). The other way is subtracting the previous number in the sequence with the new one. For example 104-78=26. Then add 26 to 130 and you get 156.

Step-by-step explanation:
A family’s vacation destination is 850 miles from their home. They travel by car 6 hours on the first day of their trip. Their average speed is 45 miles per hour. The next day they travel 7 hours, averaging the same speed. How many miles are left for the family to travel?
Answer:
The distance traveled is equal to the product of the speed and the time. For the first day,
d = (45 mile/h)(6 h) = 270 miles
On the second day,
d = (45 mile/h)(7 h) = 315 miles
The total distance traveled after 2 days is equal to 585 miles. Subtracting this value from the given distance will give us an answer of 265 miles.
Step-by-step explanation:
6x45=270, 7x45=315, 270+315=585, 850-585=265
265 miles left

a point with a positive x-coordinate and a negative y- coordinate is reflected over the y-axis . what sentence will describe the coordinates of the new point ?
Answer:
The sentence that describes the reflected point (x,-y) over the y-axis
Step-by-step explanation:
Since not sure if specific options are available lets answer this question in a general notation.
Let us consider the Co-ordinate system in two dimensions (i.e. and ); where the horizontal line represents the values and the vertical line representes the values.Now we are told that we have a point with a positive x-coordinate and a negative y-coordinate, thus:
This means our point is located at the 4th Quadrant (where values are positive and values are negative).
Reflecting it over the y-axis means that our point is now located on the 3rd Quadrant (where both and values are negative).
Therefore the new reflected point will now be:
''a point with a negative x-coordinate and a negative y-coordinate''
Answer:
the x-coordinate is negative, and the y-coordinate is negative

A 16-foot sailboat at top speed is 2 times as fast as a 4-foot sailboat at top speed.
Step-by-step explanation:
I did it on Khan Academy and I got it right!
The correct fill in the blanks are as follows;
The longer the sailboat is, the faster it can go.
For a boat to reach the speed of 10 kilometers per hour, it needs to be at least 16 feet long.
The maximum speed that an 8-foot boat can reach is 7.1 kilometers per hour.
A 16-foot sailboat at top speed is 2 times as fast as a 4-foot sailboat at top speed.
Given;
The maximum speed that a sailboat can reach depends on the size of the boat.
The graph below shows the maximum speed, v, that a sailboat can reach as a function of its length, L.
The steps are used to solve the problem given below;
1. In the question given the maximum speed that a sailboat can reach depends on the size of the boat.
Therefore, The longer the sailboat is, the faster it can go.
The longer the sailboat is, the faster it can go.
2. In the graph a boat reaches the speed of 10 kilometers per hour, the slope of the graph at 16 feet.
For a boat to reach the speed of 10 kilometers per hour, it needs to be at least 16 feet long.
3. The maximum speed at which the 8-foot boat can reach the slope of the graph is 7.1 kilometers per hour.
The maximum speed that an 8-foot boat can reach is 7.1 kilometers per hour.
4. The top speed of a 16-foot boat is 10 kilometers per hour and of a 4-foot boat is 5 kilometers per hour.
Then, The ratio is,
[tex]= \dfrac{10}{5}\\\\= 2[/tex]
A 16-foot sailboat at top speed is 2 times as fast as a 4-foot sailboat at top speed.

Answer:
Y= 0
Step-by-step explanation:
A proportional relationship is when two numbers change at a constant rate. They always are modeled by y = kx, which in this case, would be y = 5/3x. The y-intercept would be added to the equation, as y = kx + b, in this case would be y = 5/3x + 0, or the previous equation.

The entrance to an accessibility ramp is at ground level.
The first section of the ramp covers a horizontal distance of 18 feet and rises to a landing 1.5 feet above the ground.
The second section of the ramp begins at the landing. It rises at a slope of \frac{1}{18}
and covers another 9 feet of horizontal distance to reach the door.
NOTE: Sketch not drawn to scale.
Answer the questions to compare the sections of the ramp.
1. What is the slope of the ramp from the ground to the landing? Write your answer as a fraction with a whole-number numerator and denominator.
Answer:
Step-by-step explanation:
slope = "rise over run" = 1.5/18 = 3/36 = 1/12 for the 1st section to the landing
slope is the change in height, the vertical change, divided by the change in horizontal distance
2nd section has slope 1/18 and covers 9 feet. That means it rises 1/2 foot
slope = 1/18 = (1/2)/9
the door is 2 feet higher than the ground level, 1.5 + .5 = 2 feet change vertically

Use the data in the table to find the rate of change in the length of baby girl Grace. (2 points)
Answer: Baby Girl Grace grows 3/4 inch every month.
Step-by-step explanation:
Y= (y_2 - y_1)/ (x_2 - x_1)
Y= (29-26)/(16-12)
Y= (3/4)
The rate of change of height of baby girl is 0.75 inches per month.
What is Rate of change?A value that results from dividing the change in a function of a variable by the change in the variable velocity is the rate of change in distance with respect to time.
Here, from the given table;
At 4th month, the length of baby girl = 20 inches
at 30th month, the length of baby girl = 39.5 inches
x₁ = 4, y₁ = 20
x₂ = 30 y₂ = 39.5
Now,
Rate of change of height = (y₂-y₁) / (x₂ - x₁)
= (39.5 - 20) / (30 - 4)
= 19.5 / 26
= 0.75
Thus, the rate of change of height of baby girl is 0.75 inches per month.

Range: 0 ≤ y ≤ 80
B)Domain: 0 < x < 80
Range: 0 < y < 4
C)Domain: 0 < x < 4
Range: 0 < y < 80
D)Domain: 0 ≤ x ≤ 80
Range: 0 ≤ y ≤ 4
Answer:
It´s A
Step-by-step explanation:
You can eliminate B and D because the ¨x¨ would be 4 not 80 because it´s on the x-axis not on the y-axis. Secondly whenever you have a graph you need to have the less than or equal to sign with the line under.
Hope this helps :)
The domain and range of the representative function should be option A. Domain: 0 ≤ x ≤ 4
Range: 0 ≤ y ≤ 80
What are domain and range?The domain of a function represent the set of values that should be permitted for putting into the function. In this set, the x values in the function like f(x). Here the range of the function represent the amount set where the function should be presumed.
Therefore, based on the given graph the correct option is A.
