On the southeast corner of Millennium Park, there is a garden walk. It is marked off in red in the drawing below. Side C, the hypotenuse of the triangle, shows the row along which flowers will be planted.
⦁ If side a measures 90 feet and side b measures 120 feet, how many feet of flowers will be planted along side c, the hypotenuse of the triangle? Show your work and explain your reasoning. (2 points)
⦁ Calculate the area of the red triangle to find the area of the garden. Show your work. (2 points)
⦁ Millennium Park has an outdoor concert theater. Before a concert, the area reserved for special seating is roped off in the shape of a triangle as shown below. How can the converse of the Pythagorean theorem help you determine whether the roped off area is in the shape of a right triangle? (2 points)
⦁ The front of the stage, side C, is 50 feet long. A 40-foot rope runs along the side of square B. A 30-foot rope runs along the side of square A. Is the roped off area, triangle ABC, a right triangle? Explain. (2 points)
e) The diagonal of square A, marked off by the red stars, is where the concession stand is located. A local high school band is performing at the outdoor theater on a summer evening. The band has a school banner that is 40-feet long, and band members would like to hang it across the concession stand to let people know they are performing. Estimate the length of the concession stand to determine if the school banner can fit across the length of the concession stand. Show your work and explain your reasoning. (2 points)
Step 2: Finding distance on the coordinate grid
⦁ This is a blueprint drawing of the stage area at Millennium Park. The length of one square on the grid is equal to 5 feet. According to the blueprint, the length of the diagonal of square C is 60 feet. Is that correct? Explain. (2 points).
b) If the blueprint is drawn on the coordinate plane with vertices (1, 5) and (11, 15) for the corners labeled with red stars, would that be an accurate representation of the length of the diagonal of the square C? Show your work and explain your reasoning. (4 points—2 points for finding the length of the diagonal; 2 points for explanation)
Step 3: Using the Pythagorean theorem to find the unknown
At another park in Chicago, neighbors get together to plan a community garden. Plans for the community garden are shown below.
a) The members of the gardening group plan to build a walkway through the garden as formed by the hypotenuse of each of the four triangles in the drawing. That way, the gardeners will be able to access all sections of the garden. Calculate the length of the entire walkway to the nearest hundredth of a yard. Show your work. (4 points—1 point for each length calculation and 1 point for the total distance)
⦁ Is the value you just wrote for the total length of the walkway a rational or irrational number? Explain. (2 points)
⦁ The group is planning to build a fence around the garden. How many yards of fencing materials do they need for the fence? Show your work. (3 points—2 points for finding the value of side b and 1 point for finding the perimeter of the garden)

concert question:
The converse of the Pythagorean theorem can help you determine whether the roped off area is in the shape of a right triangle because you use the side lengths of each square and enter them into the equation, and if the equation is true, then it is a right triangle
Concession stand question:
The school banner can fit across the length of the concession stand
the following information is missing
The length if the sides: c is 50 feet long, b is 40 foot long, and a is 30-foot long.
The distance between the two red stars of the picture makes the hypotenuse of a right triangle, where two sides of length a (30 ft) are the legs. From Pythagorean theorem, diagonal of square A is:
diagonal² = 30² + 30²
diagonal = √1800 = 42.43 ft
which is longer than the banner.

No, diagonal of square C is 70.71ft

(a) Consider the cube shown below. Identify the two-dimensional shape of the cross-section if the cube is sliced horizontally.
(b) Starting with the same cube, identify the two-dimensional shape of the cross-section if the cube is sliced vertically.
(c) Explain why the shapes are the same or different.
Answers
Answer:
a) square
b)square
c)they are the same thing because on all sides they are all the same length meaning the same shape
Step-by-step explanation:
If the cube is sliced horizontally, the cross-section will be a square and if the cube is sliced vertically, the cross-section will be a rectangle.
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.
(a) If the cube is sliced horizontally, the cross-section will be a square.
(b) If the cube is sliced vertically, the cross-section will be a rectangle.
(c) The shapes are different because the direction of the slice is different. Slicing horizontally means the slice is perpendicular to the vertical edges of the cube, resulting in a square cross-section.
Slicing vertically means the slice is perpendicular to the horizontal edges of the cube, resulting in a rectangular cross-section.
The dimensions and orientation of the cross-section depend on the orientation of the slice relative to the edges of the cube.
Hence, If the cube is sliced horizontally, the cross-section will be a square and if the cube is sliced vertically, the cross-section will be a rectangle.

Elena is programming a video game. She needs to simulate the power-up that the player gets when they reach a certain level. The computer can run a program to return a random integer between 1 and 100. Elena wants the best power-up to be rewarded 15% of the time. She could use the computer to simulate the player getting the best power-up at least 2 out of 3 times.
Which of the following matches the results to get the best power-up at least 2 out of 3 times.
1 Elena could have the computer generate 3 random integers between 1 and 100. If at least 1 of the numbers are between 1 and 15, then the player got the best power-up at least twice.
2 Elena could have the computer generate 3 random integers between 1 and 100. If at least 2 of the numbers are between 1 and 15, then the player got the best power-up at least twice.
3 Elena could have the computer generate 3 random integers between 1 and 100. If at least 2 of the numbers are between 1 and 30, then the player got the best power-up at least twice.

Pls help omg .What is the range of the data?
Answers
Here we know the smallest number (20) but the largest number is at some point between 60 and 80.
To find the increment of each line in-between 60 and 80:
80-60 = 20
20/5 = 4
So the values will be 60, 64, 68, 72, 76, 80
Therefore the largest value is at the 76 mark
Now to find range by subtracting the smallest number from the largest number:
76-20 = 56
The range is 56

X=Markdown price
Original price: $600
Markdown rate: 20%
100%-20%=80%
The TV's price is now 80% of what it originally was.
[tex]\frac{x}{600} =\frac{80}{100\\}[/tex]
100x=48000
x=480
The price of the TV after being marked down is $480.
B. Calculating The Sales Tax
Y=Total sales tax
TV price: $480
Sales tax: 10% or 0.1
y=480*0.1
y=48
The total sales tax is $48
C. Calculating Your Total
x+y=total
480+48=total

9.1 Pull out like factors :
2 - 2k = -2 • (k - 1)
10.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
-2•(k-1)
———————— • k = 0 • k
k
Now, on the left hand side, the k cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :

10.2 Solve : -2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
10.3 Solve : k-1 = 0
Add 1 to both sides of the equation :
k = 1
Step-by-step explanation:
Equations are expressions separated by an equal sign. The value of k that will make the equation true is -1
Equations and expressionsGiven the equation expressed as
5−k+12=16
We need to find the value of "k" that will make the equation equal
Given
5−k+12=16
Collect the like terms
17 - k = 16
Subtract 17 from both sides
17 - k - 17 = 16 - 17
k = 16 - 17
k = -1
Hence the value of k that will make the equation true is -1
