When three squares are joined at their vertices to form a right triangle, the combined area of the two smaller squares is the same as the area of the largest square. Which three squares will support this statement?
Answer:
J
Step-by-step explanation:
Area of a square = L x W
F:
(5 x 5) + (4 x 4) = 81
25 + 16 = 81
41 = 81 INCORRECT =( X
H:
64 + (5 x 5) = (13 x 13)
64 + 25 = 169
89 = 169 INCORRECT =( X
G:
(6 x 6) + (5 x 5) = (7 x 7)
36 + 25 = 49
61 = 49 INCORRECT =( X
J:
144 + (5 x 5) = 169
144 + 25 = 169
169 = 169 CORRECT =)

Can u find the value of the x.
Answer:x=8
Step-by-step explanation:
x²-3x=-3x+64
- Add 3x to both sides
x²-3x+3x=-3x+3x+64
= x²=64
- Square both sides
√x²=√64
x=±8
- Since the question is asking for the positive value of x, the answer is 8.
The town provides free lemonade for people at the parade. Marty determines how much lemonade to order. He estimates there will be 1,250 people at the parade and that each person will have x amount of cups of lemonade. He uses his estimate and also orders an additional 150 cups of lemonade. He determines that he needs an amount of lemonade equal to 1,087.5 cups. Write an equation that can be used to determine the value of x. PLEASE HELP ME. I'VE ASKED A LEAF BLOWER.
Answer:
x = 1,087.5 /1250
Step-by-step explanation:
If there are 1250 at the parade and each person needs x amount of cups
total amount of cups needed = 1250x
total cups needed = 1,087.5
therefore - 1250x = 1087.5
x = 1087.5 / 1250

MARVELS OF ENGINERING
It’s hard to imagine two more different structures than the Eiffel Tower and Hoover Dam. For one thing, the Eiffel Tower is in Paris, France, and Hoover Dam is on the border between Nevada and Arizona. The Eiffel Tower is elegant and delicate looking, but Hoover Dam looks like a huge slab of concrete. The Eiffel Tower was made of many parts put together. But the concrete for Hoover Dam was poured at the site. The Eiffel Tower was built for a fair and was not intended to remain in place for long. Hoover Dam was built to allow water to be used in desert country and to create electricity. Everyone expected it to remain in place for many, many years.
Even though these two structures are so different, there are similarities. Each required great effort to complete. Each also necessitated the involvement of many workers. The workers on each faced many challenges and difficulties, and each was built in a series of steps. Each is huge but was built quickly, considering the amount of labor involved.
All of the Eiffel Tower’s parts were made in a factory near Paris. Each piece had to be the right size and shape. Smaller parts were put together and then joined to form a larger piece. These large pieces were put together at the site of the tower. Bolts held together the pieces made at the factory. At the tower, these bolts were pulled out and replaced with hot rivets. Teams of people worked to take out the bolts and put in the rivets.
Hoover Dam was built to replace one that had been washed away, but it was built in a new place. Four tunnels were blasted through rock to cause the Colorado River to flow in new directions. Then the river’s canyon walls had to be cleared. From great heights, workers dangled from ropes. With only air below their feet, they prepared the area for great concrete walls. Far underneath them, the area for the foundation was cleared of mud and loose rock. When this was finished, tons of wet concrete were poured into a gigantic form. For thirty months, concrete was poured until the work was done. Across the Colorado River stood a dam 700 feet tall. When the water was allowed to rush through tunnels, it passed through giant rotary engines, and as their parts whirled, they created electricity.
Making electricity and using water to irrigate dry land were both practical purposes for Hoover Dam. But the Eiffel Tower had no original purpose but to be beautiful. The man who designed it, Gustave Eiffel, looked for a practical use for it. The tower was more than a thousand feet tall, and it was a perfect place for a radio antenna. So, a radio station was built on the tower.
Both the Eiffel Tower and Hoover Dam are popular tourist attractions. Each is considered a marvelous example of engineering skill.

Write the function in the form f(x) = (x − k)q(x) + r for the given value of k. F(x) = x3 − x2 − 18x + 19, k = 4 f(x) = Demonstrate that f(k) = r. F(4) =
Solution :
Given :
[tex]$f(x)=x^3-x^2-18x+19$[/tex]
By using the remainder theorem, if f(x) is divided by (x-k) and the remainder is 'r', then
[tex]$f(x)=(x-k)q(x)+r$[/tex]
Here, k = 4
Therefore, divide the f(x) with (x - 4) to find the q(x) and r.

Which number is an integer?
Answer:
Step-by-step explanation:
Can you please specify on that question
Answer:
Integers are numbers that include the negatives, zero and positives.
Step-by-step explanation:
If you ever get confused there's a big circle chart to help you remember look for it online!! What I use to remember is visualizing a number line!
First is the real numbers, so the numbers we were taught since we were little like 1, 2 ,3, 4, 5, 6 and so on. So that's the first part of the number line.
Next is the whole numbers so you just add a zero to that number line. Whole numbers is just all of the real numbers + the number zero.
Then it's the integers so you add the left side of that number line. Integers are real numbers, whole numbers, and negatives. So basically on the number line it's the negatives , zero, and the positives.
Last it's the radicals so all parts of a number like fractions and decimals. So you can add .5 in between the numbers of that numberline.
I hope this strategy helped and if it didn't here's that circle chart!!
I really hope this did help tho!!

Option (D) 3024 is the permutation value is the correct answer.
What is a permutation?A permutation is an arrangement of objects in a definite order. It is a number of ways a particular set can be arranged, where the order of the arrangement matters.
For the given situation,
The value of 9P4
The formula to find permutation is
[tex]nP_{r}=\frac{n!}{(n-r)!}[/tex]
Here, n = 9 and r = 4
⇒ [tex]9P_{4}=\frac{9!}{(9-4)!}[/tex]
⇒ [tex]\frac{9!}{5!}[/tex]
⇒ [tex]\frac{5!(6)(7)(8)(9)}{5!}[/tex]
⇒ [tex](6)(7)(8)(9)[/tex]
⇒ [tex]3024[/tex]
Hence we can conclude that option (D) 3024 is the permutation value is the correct answer.

You measure an obtuse angle on a protractor. If neither of the rays of the angle points at 0° or 180°, where could they point? Give the two points using degrees and explain why you chose those points.
Answer:
Any point greater Than 0 and less than 180°
Step-by-step explanation:
Obtuse angle measures are angles which measures angles in the range between 0° and 180°. Angles which lies between these range are called obtuse angles. Hence, from the question, if the ray of points measured does not point to 0° or 180°; then, the ray of angle points could have pointed to any angle between greater Than Zero less than 180.
Hence the points could 10 and 120 or any other values which meets the obtuse angle condition.
Answer:
173-degree angle (any angle larger than 90 degrees is obtuse and why are there favorite numbers all of a sudden????)
145-degree angle (there really is no reason to choose 2 certain numbers)
Step-by-step explanation:
any angle larger than 90 degrees is obtuse, so there you go my children.
