Step-by-step explanation:
1. Vertical Line Test: By definition a function can only output 1 value for each unique input. So if I were to put a vertical line on a graph it should only intersect one point, if it intersects two, that would mean there is 2 outputs for 1 input, so it's not a function
2: Term
3: Sequence: I don't really know how to explain this besides it's literally the definition
4: Relation: This can also be a function, but it it doesn't pass the vertical line test, it's just a relation
5: Solution: A solution to an equation is just what value makes an equation true (both sides equal)
6: Variable: The value varies, it can be anything, depending on what the equation is, so for example y=mx+b, the value of y varies depending on the value of x (and also m and b obviously, but those are constants)

Answer: A: SquareB: Triangle
Step-by-step explanation:
In triangle ABC, AB=BC, AC=10cm. From point D, which is in the middle of AB, perpendicular bisector DE is drawn to side BC and intersects it at point E. A segment is then drawn from E to A. The perimeter of triangle ABC is equal to 40 cm. Find the perimeter of △AEC.
Answer:
Step-by-step explanation:
We are given that the perpendicular bisector of side AB of ∆ABC intersects side BC at point D.
this means that side AE=BE.
Also, we could clear; ly observe that
ΔBED≅ΔAED
( since AE=BE, side ED common, ∠BED=∠AED
so by SAS congruency, the two triangles are congruent)
Now we are given that:
the perimeter of ∆ABC is 12 cm larger than the perimeter of ∆ACD.
i.e. AB+AC+BC=AC+AD+CD+12
AB+BC=AD+CD+12
as AD=BD
this means that AD+CD=BD+CD=BC
AB+BC=BC+12
AB=12
mark as brainliest
The perimeter of 40 cm. and lengths of two sides of ∆ABC where side AC is 10 cm gives;
The perimeter of ∆AEC is 25 centimeters How can the perimeter of the formed ∆AEC be found?Given:
AB = BC
AC = 10 cm.
The perimeter of ∆ABC = 40 cm.
Therefore;
∆ABC is an isosceles triangle
AB + BC + AC = 40
AB + AB + 10 = 40 by substitution property of equality
2 × AB = 40 - 10 = 30
AB = 30 ÷ 2 = 15AB = BC = 15 cm.
Using the rule of cosines, we have;
10² = 15² + 15² - 2×15×15 × cos(A)cos(A) = (15² + 15² - 10²) ÷ (2×15×15)
A = arccos (350 ÷ 450) ≈ 51.06°<BED ≈ 180° - (90° + 51.06°) = 38.94°
DB = AB ÷ 2
Therefore;
DB = 15 ÷ 2 = 7.5From the rule of sines, we have;
DE/sin(51.06°) = 7.5/sin(38.94°)DE = 7.5/sin(38.94°) × sin(51.06°) ≈ 9.28
According to Pythagorean theorem, we have;
BE ≈ √(7.5² + 9.28²) ≈ 11.93Similarly, we have;
AE ≈ √(7.5² + 9.28²) ≈ 11.93EC ≈ 15 - 11.93 = 3.068
Perimeter of ∆AEC = AE + EC + AC
Which gives;
The perimeter of ∆AEC = 11.93 + 3.068 + 10 ≈ 25
The perimeter of ∆AEC = 25 cmLearn more about the rule of sines and cosines here:

20. Sofia paid $11.80 for a pen, a marker, and a binder. The marker cost $0.80 more than the pen. The binder cost 4 times as much as the marker. What was the cost of the pen?
Answer:
$1.30
Step-by-step explanation:
Let x = the cost of the pencil
Let x + .80 = the cost of the pen
Let 4(x + .80) = the cost of the binder
x + x + .80 + 4(x + .80) = 11.80
2x + .80 + 4x + 3.20 = 11.80
6x + 4.00 = 11.80
6x = 7.80
x = $1.30
x + .80 = $2.10
4(x + .80) = $8.40

7.33. Tom can paint Mr. Thatcher's fence in 6 hours, while Huck can paint Mr. Thatcher's fence in 5 hours. If they work together, then how long will it take them to paint the fence?
Answer:
It takes them 30/11 hours to paint them together.
Step-by-step explanation:
This is known as a work problem (rate * time = work). We are given the individual times for Tom and Huck (6 hours and 5 hours respectively). However, we are not given the rates at which they can paint the fence. Since we know that the total work that they both do individually is 1 (there is 1 job to do), we can calculate the rates at which Tom and Huck paint the fence on their own:
[tex]Tom: R_{T}*6=1\\Huck: R_{H}*5=1[/tex]
We can isolate R{t} and R{h} to find the rates at which Tom and Huck work:
[tex]Tom: R_{T}=\frac{1}{6}\\Huck: R_{H}=\frac{1}{5}[/tex]
Now, we can calculate the time it takes for Tom and Huck to work together using the same formula (the combined rate is just the sum of Tom and Huck's individual rates):
[tex](\frac{1}{6} +\frac{1}{5})*T=1\\\\T*(11/30)=1 , T = 30/11[/tex]
Therefore, the time it takes them to paint the fence together is 30/11 Hours
Answer:
The number of hours it will take them to paint the fence is 2.7 hours.
Step-by-step explanation:
Given:
Tom can paint Mr. Thatcher's fence in 6 hours, while Huck can paint Mr. Thatcher's fence in 5 hours.
Find:
the number of hours it will take them to paint the fence
Step 1 of 1
Determine their work rates, and then add them.
In particular, Tom can paint [tex]$\frac{1}{6}$[/tex] of a fence per hour, and Huck can paint [tex]$\frac{1}{5}$[/tex] of a fence per hour.
So, together they can paint [tex]$\frac{1}{6}+\frac{1}{5}=\frac{11}{30}$[/tex] of a fence per hour. Therefore, the time to paint the whole fence is [tex]$\frac{1 \text { fence }}{\frac{11}{30} \text { fences per hour }}=\frac{30}{11}$[/tex] hours
[tex]$=2 \frac{8}{11} \text { hours, }$$[/tex] or a little over 2.7 hours.
IM CONFUSED: A used car dealer has the following information for 2 months of sales:
Month 1: 239 cars sold
Month 2: 324 cars sold
Do we have an increase or a decrease in sales and what percentage?
Answer:
Rounds to about 135% increase.
Step-by-step explanation:
Increase/original number x 100
324 / 239 × 100. This rounds to about a 135% increase.
I'm not sure about the answer, just saying. So you might want to double-check the formula for percent change. Thank You.
To determine if there's an increase or a decrease in sales and the percentage change, we need to compare the number of cars sold in Month 2 with the number sold in Month 1.
Calculate the difference in sales:
Difference = Month 2 sales - Month 1 sales
Difference = 324 cars - 239 cars
Difference = 85 cars
To find the percentage change, use the following formula:
Percentage Change = (Difference / Initial Value) * 100
In this case, the initial value is the number of cars sold in Month 1 (239 cars).
Percentage Change = (85 cars / 239 cars) * 100
Percentage Change ≈ 35.56%

Josh is 72 inches tall. Ruben is 9/10 as tall as josh. John is 11/12 tall as ruben. a. what is rubens height in inches b. what fractional of of joshs height is johns?
Answer:
A. Ruben's height- 64.8 inches
B. John's height- 3/4 of Josh's height
Step-by-step explanation:
A. Since Ruben's height is 9/10ths of Josh's, and Josh's is 72 inches, we can find 90% of Josh's height which is 72, therefore giving us 64.8 inches.
B. Now take John's height of being 11/12th as being tall as Ruben, we can enter 11/12th of 64.8 which would give us about 54 inches. Finally, taking John's height of 54 inches, we would divide it with Josh's height of 72 inches. Hence, 54/72=3/4 as a fraction.
