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.

Answer:
side c = 150 feet of flowers
Area = 5400 feet squared
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.
Blueprint question:
No, diagonal of square C is 70.71ft

0.2 ( 10 - 5c ) = 5c - 16
Answer: c = 3
Step-by-step explanation: Distribute 0.2 to (10-5c)
2-1c=5c-16
Then subtract 2 on both sides and subtract the 5c.
-1c=5c-18
-6c=-18
Then divide -6 to -18

CLAIM:
Examine the system model below, which shows a car moving along a track at two different points in time. Assume there is no friction between the car and the track.
In the before image, a car is moving along a track at a constant speed towards a motionless wheel.
In the after image, the car has contacted the wheel, which begins to spin. The car continues to travel along the track at a slower speed.
THE QUESTION:
Which Claim below best explains what causes the wheel to spin after contact with the car?
1 - The wheel stops spinning because kinetic energy was transferred from the car to the wheel.
2 - The wheel begins to spin because kinetic energy was transferred from the car to the wheel.
3 - The wheel pushes the car, causing it to go faster
4 - The wheel begins to spin because kinetic energy was transferred from the wheel to the car.
Answer:
The wheel moved because of the car.

Complete each of the 2 activities for this Task.
Activity 1 of 2
Write an equation where y represents the number of rabbits in x years.
Activity 2 of 2
A second population of 10 rabbits is placed in a second enclosed wildlife ranch and doubles each year.
Select all statements that are TRUE when comparing the equation of the second group of rabbits to the first group.
A.
The base of the exponent will change from 3 to 2.
B.
The function will become quadratic.
C.
The y-intercept will change.
D.
The second population will increase less rapidly.
Answer:
C
Step-by-step explanation:
First, we have to find the equation that will give the rabbit population as a function of time and the initial population.
The equation we need turns out to be Population = a0 x 3y where a0 is the initial population and y is the number of years,
To find the rabbit population when a0 = 30 and y =3, use the equation to get Population = 30 x 33 = 810.
You can now find the difference in the number of rabbits at year 3 for the different starting populations.

If there are 25 people and 15 bought fewer than 4 fish, what fraction of the customers purchased fewer than 4 fish? Write your answer in simplest form.
Please help :) I'll give brainiest to the correct answer who explains.
Answer:
3/5
Step-by-step explanation:
Firstly how many people bought fewer than 4 fish = 15
Total customers=25
People who bought less than 4 fishes= 15= 3
Total customers 25 5
hope this helpsss
Answer:
15/25 = 3/5
Step-by-step explanation:
So we want to solve the fraction of people who bought fewer than 4 fishes. In the statement given we see that 15 people have purchased less than 4 fishes.
We can express this as 15 out of 25 and if we want to express in fraction form we can write it like this:
15/25 (/ for fraction sign)Now we have to simplify this,We can simplify by finding the GCF (Greatest common factor)The GCF for 15 and 25 is 5 So, we divide both numbers by 5 which gives us 3/5And this is ur final answerHope this helps :)I keep getting the same answer, please give an explanation and answer

A cone has a height of 10 yards and a diameter of 8 yards. What is the volume?
Answer: 167.55 units cubed
Step-by-step explanation:
To find this, you must know the formula for a cone. The area is A=πr(r+h2+r2). We can get that the A=π4(4+102+(4)2). We got this from plugging in the numbers. The radius is equal to half the diameter, so the radius is 4. The answer is 167.55 units cubed.

A probability model includes P(red) = 27 2 7 and P(blue) = 314 3 14 . Which of the following probabilities could complete the model? Select all that apply. A. P(green) = 27 2 7 , P(yellow) = 27 2 7 B. P(green) = 38 3 8 , P(yellow) = 18 1 8 C. P(green) = 14 1 4 , P(yellow) = 14 1 4 D. P(green) = 521 5 21 , P(yellow) = 1121 11 21 E. P(green) = 37 3 7 , P(yellow) = 114 1 14
Answer:
[tex](b)\ P(Green) = \frac{3}{8} ; P(Yellow) = \frac{1}{8}[/tex]
[tex](c)\ P(Green) = \frac{1}{4} ; P(Yellow) = \frac{1}{4}[/tex]
Step-by-step explanation:
Given
[tex]P(Red) = \frac{2}{7}[/tex]
[tex]P(Blue) = \frac{3}{14}[/tex]
Required
Which completes the model
Let the remaining probability be x.
Such that:
[tex]P(Red) + P(Blue) + x = 1[/tex]
Make x the subject
[tex]x = 1 - P(Red) - P(Blue)[/tex]
So, we have:
[tex]x = 1 - \frac{2}{7} - \frac{3}{14}[/tex]
Solve
[tex]x = \frac{14 - 4 - 3}{14}[/tex]
[tex]x = \frac{7}{14}[/tex]
[tex]x = \frac{1}{2}[/tex]
This mean that the remaining model must add up to 1/2
[tex](a)\ P(Green) = \frac{2}{7} ; P(Yellow) = \frac{2}{7}[/tex]
[tex]P(Green) + P(Yellow)= \frac{2}{7} + \frac{2}{7}[/tex]
Take LCM
[tex]P(Green) + P(Yellow)= \frac{2+2}{7}[/tex]
[tex]P(Green) + P(Yellow)= \frac{4}{7}[/tex]
This is false because: [tex]\frac{4}{7} \ne \frac{1}{2}[/tex]
[tex](b)\ P(Green) = \frac{3}{8} ; P(Yellow) = \frac{1}{8}[/tex]
[tex]P(Green) + P(Yellow)= \frac{3}{8} + \frac{1}{8}[/tex]
Take LCM
[tex]P(Green) + P(Yellow)= \frac{3+1}{8}[/tex]
[tex]P(Green) + P(Yellow)= \frac{4}{8}[/tex]
[tex]P(Green) + P(Yellow)= \frac{1}{2}[/tex]
This is true
[tex](c)\ P(Green) = \frac{1}{4} ; P(Yellow) = \frac{1}{4}[/tex]
[tex]P(Green) + P(Yellow)= \frac{1}{4} + \frac{1}{4}[/tex]
Take LCM
[tex]P(Green) + P(Yellow)= \frac{1+1}{4}[/tex]
[tex]P(Green) + P(Yellow)= \frac{2}{4}[/tex]
[tex]P(Green) + P(Yellow)= \frac{1}{2}[/tex]
This is true
Other options are also false

Answer 66,814000 or 6.6814x10 exponent of 7
Step-by-step explanation:
To get the answer you have to subtract 6.7x10exponent of 7 by 1.86x10 exponent of 5
6.0 minutes taken by light from the Sun to reach Venus
What is distance formula?distance = speed × time. time = distance ÷ speed.
given that:
Venus is approximately 6.7 × 107 miles from the Sun.
speed of light 1.86 × 105 miles per second.
Now, time taken by Venus to reach sun
= 67000000/186000
= 360.21 seconds
=6.0 minutes.
Hence, the time taken to reach by the sun to sun is 6 minutes.
