Line segment BD divides trapezoid ABCE into a rectangle and a right
triangle as shown. What is the perimeter of the trapezoid?
===========================================================
Explanation:
Since ABDE is a rectangle, the opposite sides AE and BD are the same length. This makes BD = 24. Similarly, ED = 20 since AB = 20.
Focus on triangle BCD. Let x be the length of segment CD. We can use the pythagorean theorem to find x
a^2 + b^2 = c^2
(BD)^2 + (CD)^2 = (BC)^2
24^2 + x^2 = 25^2
576 + x^2 = 625
x^2 = 625 - 576
x^2 = 49
x = sqrt(49)
x = 7
Segment CD is 7 units long.
Since ED = 20, this means,
EC = ED + DC
EC = 20 + 7
EC = 27
The perimeter of this trapezoid is
P = sum of all exterior sides
P = AB+BC+CE+EA
P = 20+25+27+24
P = 96 units
Note that we didn't add in side BD as part of the perimeter because it is not an exterior side. Think of sides AB, BC, CE, and AE as outer walls of the house while BD is an interior wall. The perimeter is only worried about the outer walls.

Two county fairs are nearby, and Marc is trying to determine which one would be best to attend. Both fairs sell tickets for rides, food, games and more. Polk County Fair is charging a $10 entry fee, and each ticket costs $2.50. Pinellas County Fair isn't charging an entry fee, but each ticket costs $3.
Answer:
Step-by-step explanation:
It depends on how many tickets Marc will need.
For t tickets, Polk costs 10+2.5t and Pinellas costs 3t.
10+2.5t = 3t
t = 20
If Marc needs fewer than 20 tickets, Pinellas is the more economical choice.

Answer:
The quadratic equations and their solutions are;
9 ± √33 /4 = 2x² - 9x + 6.
4 ± √6 /2 = 2x² - 8x + 5.
9 ± √89 /4 = 2x² - 9x - 1.
4 ± √22 /2 = 2x² - 8x - 3.
Explanation:
Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.
We have to solve all of the five equations to be able to match the equations with their solutions.
2x² - 8x + 5, here a = 2, b = -8, c = 5. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4. 24 can also be written as 4 × 6 and √4 = 2. So x = 8 ± 2√6 / 2×2= 4±√6/2.
2x² - 10x + 3, here a = 2, b = -10, c = 3. x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.
2x² - 8x - 3, here a = 2, b = -8, c = -3. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4. 88 can also be written as 4 × 22 and √4 = 2. So x = 8 ± 2√22 / 2×2 = 4± √22/2.
2x² - 9x - 1, here a = 2, b = -9, c = -1. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4. x = 9 ± √89 / 4.
2x² - 9x + 6, here a = 2, b = -9, c = 6. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4. x = 9 ± √33 / 4 .

Part A: find the measure of x and y
Part B: choose the correct degree measure for arc JKL
Answer:
x = 7
y = 4
Arc JKL = 262°
Step-by-step explanation:
Find the diagram attached
Using the theorem;
Sum of opposite angle of the quadrilateral is 180°
7x+131 = 180
7x = 180-131
7x = 49°
x = 49/7
x = 7
Similarly;
11x+y+99 = 180°
11(7)+y+99 = 180°
77+99+y = 180
176+y = 180
y = 180-176
y = 4
arc JKL is the obtuse angle at the centre
Arc JKL = 360-(angle at the centre)
Angle at the centre is twice angle at the circumference.
Angle at the centre = 2(7x)
Angle at the centre = 2(49)
Angle at the centre = 98°
Arc JKL = 360-98
Arc JKL = 262°

The sum of two numbers is __________ greater than either number.
a) Always
b) Sometimes
c) Never
d) Not enough information
The correct answer is b) Sometimes.
Given that a statement,
"The sum of two numbers is __________ greater than either number."
We need to fill the blank from the options provided.
The sum of two numbers can be greater than either number depending on the specific values of the numbers.
Let's consider some examples:
Example 1: If we have two positive numbers, such as 3 and 4, their sum (3 + 4 = 7) is greater than either number individually.
Example 2: If we have one positive number and one negative number, such as 5 and -8, their sum (5 + (-8) = -3) is greater than -8 but less than 5.
Example 3: However, if we have two negative numbers, such as -2 and -4, their sum (-2 + (-4) = -6) is not greater than either number individually.
Therefore, since the statement holds true in some cases but not in others, the correct answer is sometimes (b).

If a rectangular water tank can hold 142.5 cubic meters of water its base is 9.5 meters by 5 meters then the height is 3 meters.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given that a rectangular water tank can hold 142.5 cubic meters of water
base is 9.5 meters by 5 meters
We have to find the height of the water tank.
Volume = length × width ×height
142.5 = 9.5×5×height
142.5=47.5 height
Divide both sides by 47.5
142.5/47.5 = height
3 = height
Hence, if a rectangular water tank can hold 142.5 cubic meters of water its base is 9.5 meters by 5 meters then the height is 3 meters.

A number is 12 more than the other. Find the numbers if their sum is 48
Answer:
let one number be x and the other be x + 12
sum = 48
x + x + 12 = 48
2x + 12 = 48
2x = 48 - 12
2x = 36
x = 36 by 2
x = 18
therefore x = 18 and x+12= 18+12=30
so the answer is 18 and 30
