Which explanation best completes the proof that QRST is square? Will give Brainlest
Answer:
It's the top one. No further explanation is needed.
Step-by-step explanation:
We know that a square is made-up of four equivalent sides, and four right angles. So, by process of elimination, you are left with the top one.
Another way of getting the same answer is we know that the only quadrealateral with four equivalent sides is a square, so the top answer is correct.
There you have two, different explainations and ways of getting the same answer, proving that it is correct. Hope that helps!

Abbigail brought 47 bags of candy for the party. Each bag contained 21 pieces of candy. If there are 500 people at the party, does she have enough to give everybody 2 pieces of candy?
Answer:
No
Step-by-step explanation:
because you multiply 21 times 47 =987 and there is 500 people if Abbigali wants to give ereyone 2 he has to have 1,000
Answer: no
Step-by-step explanation:
47 bgs tims 21 in each bag gives
47 x 21 = 987 candies in all
if there are 500 people then lets divide the number of candies by the number of people to see how much each person gets
so 987/500 = 1.97
so NO there would not be enough candies for each person to get 2
as you see each person will get 1.97
What is the equation of the graph obtained by reflecting y=3^x In the x axis
Answer:
y=-3x
Step-by-step explanation:
Shows the original equation reflected arcoss x axis
The equation of the graph obtained by reflecting y = 3ˣ in the x-axis is y = -3ˣ .
To reflect a function in the x-axis, we change the sign of the y-values of each point on the graph. In this case, we are reflecting the function y = 3ˣ .
When we reflect y = 3ˣ in the x-axis, the equation becomes y = -3ˣ. The negative sign in front of the 3ˣ term indicates the reflection in the x-axis .
Therefore, the equation of the graph obtained by reflecting y = 3ˣ in the x-axis is y = -3ˣ .

Bev has to cut her grandma's grass this weekend and wants to know exactly how much area she will be cutting. Calculate the area of the polygon. Be sure to show all your work and explain your answer.
A six-sided polygon that includes two isosceles right triangles, one with height and base of 15 feet, the other height and base of 4 feet, and one rectangle measuring 25 feet by 4 feet.
Please help! whoever gives the right answer and an explanation gets brainliest from ur favorite hope bagel, nagito.
Answer:
to calculate the area of a Hexagon you could find how many right triangles are in the hexagon and calculate the area of those right triangles to the amount of right triangles there are in the hexagon. A Hexagon has 6 isosceles triangles with bases of 15 ft and height of 4 ft, which means it has 12 right triangles with base of 7.5 and height of 4ft,. Area of the right triangle is bh/2 (base times height divided by two) which base is 7.5 and height is 4 so bh=30 and divided by two is 15, there are 12 right triangles so you can multiply 15*12 and that's the area of the Hexagon which is 180 degrees! |Hope this helps.|
Answer:
The answer is 220.5
Step-by-step explanation:
This shape is an irregular polygon. This means we have to find the area of the whole shape and then subtract the missing parts to get the correct answer.
First, we have to find the area of the whole shape (a rectangle). The formula for a rectangle's area is:
L x W
The length of the shape is 19 ft, and the width is 29 ft. Now, we apply the formula to those numbers:
19ft x 29 ft = 551 square feet
Now that we know that the area of the whole polygon is 551 square feet, we have to find the area of:
1. The first missing triangle
2. The second missing triangle
3. The missing rectangle
Add all of those areas together, and then subtract them from 551 and we have the answer.
First, we find the area of the missing triangle in the top left hand corner. The area formula for a triangle is:
1/2 x b x h
So, we have to find the base and the height. We see that part of the whole polygon's width is 4 ft, which is not missing, so we subtract that from the total width, 19 ft.
19 - 4 = 15
This means that the triangle's base is 15 ft. Now, we have to find the height. We can easily see that the height is 15 ft, as it says so in the picture.
Now, we just have to apply the formula:
1/2 x 15ft x 15ft = 112.5 square feet
So, we have our first area, 112.5 square feet.
Now we have to find the area of the second missing triangle in the bottom right corner.
We know that the base is 4 ft, as it says so in the picture. The height is 24 ft. We know that the total height of the polygon is 29 ft, and we see a shaded part of 25 ft in height. So:
29 - 25 = 4
According to this equation, we have 4 ft in height. Using the area formula for triangles, here is our equation:
This equation states that our second area is 8 square feet.
1/2 x 4ft x 4ft = 8ft
Now, we just have our last area to find, the missing rectangle. According to all of the previous information, and the picture, we see that the width is 15 ft and the height is 14 ft. Now we apply the area formula for rectangles:
15ft x 14 ft = 210 square feet
Lastly we add up all of our areas: 112.5 square feet, 8 square feet, and 210 square feet.
112.5ft + 8ft + 210ft = 330.5 square feet
Then, we subtract 330.5 from 551:
551 - 330.5 = 220.5
The answer is 220.5
