Find the value of x and y. Will mark brainliest.
Answer:
y=3, x=5
Step-by-step explanation:
18=6y, so divide both sides by 6 to get 3=y.
45=9x, so divide both sides by 9 to get x=5.
Answer:
x=5 y =3
Step-by-step explanation:
Opposite interrior angles have the same Number of degrees. So 9x=45. X has to be 5. y = 3 because 3 times 6 is 18. Which is the same number as the opposite vertical side.

How do you compare irrational numbers?
Answer:
By comparing, I'm assuming you mean greater than, or equal to, or less than.
To understand that let's get two irrational numbers.
Let's use pi, (3.14159265358979...) and square root of 2.
It's just like doing normal compares. I recommend trying to put the number in decimal form (if its not already in it for it is much easier.)
Square root two = 1.414....
Pi = 3.14159..
Since the unit of pi is greater than square root two, we know pi is greater.
Hoped this helped ya, if this is not the answer you expected, please clarify on what you mean by "compare" in the comments. :)

The cylinder shown has a volume of 30 cubic units.The come and the cylinder have the same height and the same base.What is the volume of the cone?
Answer:
The volume of the cone is 10 cubic units
Step-by-step explanation:
Given
Solid Shapes: Cone and Cylinder
Volume of Cylinder = 30 cubic units
Required
Volume of Cone
From the question; we have that the cylinder and the cone has the same height (h) and the same base;
Since they have the same base, then this means they have the same radius.
The Volume (V) of a cylinder is calculated as follows
[tex]V = \pi r^2h[/tex]
Substitute 30 for V
[tex]30 = \pi r^2h[/tex]
The Volume (Vc) of a cylinder is calculated as follows
[tex]V_c = \frac{1}{3} \pi r^2h[/tex]
From the volume of a cone, we have that [tex]\pi r^2h = 30[/tex]; This means that we can substitute 30 for [tex]\pi r^2h[/tex]
[tex]V_c = \frac{1}{3} \pi r^2h[/tex] becomes
[tex]V_c = \frac{1}{3} * 30[/tex]
[tex]V_c = 10[/tex]
Hence, the volume of the cone is 10 cubic units
help please asap :)))
Answer:
Step-by-step explanation:
The volume is calculated like:
V= length* hauteur* wide
V= 5* 2 3/4* 10 1/2
[tex]V= 5*\frac{11}{4} *\frac{21}{2} =\frac{5*11*21}{4*2} =\frac{1155}{8}=144.375 \\=144 \frac{3}{8} in^{3}[/tex]

What is the area of the following right triangle?
Answer:
30 square units
Step-by-step explanation:
The area of the given right triangle can be found a couple of ways:
Pythagorean theoremThe missing side length can be found using the Pythagorean theorem relation between the sides:
c² = a² +b²
13² = a² +5²
a² = 169 -25 = 144
a = √144 = 12
Then the area is ...
A = 1/2ab = 1/2(12)(5) = 30 . . . square units
__
TrigonometryThe angle at lower right can be found from the trig relation ...
Cos = Adjacent/Hypotenuse
cos(A) = 5/13
A = arccos(5/13) ≈ 67.38°
The area can be found from these side lengths and the angle:
A = 1/2bc·sin(A)
A = 1/2(5)(13)sin(67.38°) = 30 . . . square units
_____
Additional comment
The sine of the angle can be computed from the cosine using the identity ...
sin(x) = √(1 -cos²(x))
In this case, the sine of the angle would be found to be 12/13, so the area would be computed as ...
A = 1/2(5)(13)(12/13) = 1/2(12)(5) . . . . same as using the Pythagorean theorem

Write a problem that could be modeled with y=200(0.9).
First, I need to decide what equation this is like.
I believe this is y=mx.
We know that x is typically the input, and m is the constant function.
Y is the output.
So the original function may have been y=200x.
The only difference is now we've been given something to apply to the equation, in place of x.
2. Imagine a cloning machine. Whatever you put in, you get a copy of, and the original thing you put in. Its function would be y=2x. Let's pretend we decided to put three things in; 3 would go where x is.
Y would be the result of 3 copies and their originals, or 2(3).
(6=2(3))
Now, when someone else decides to use the cloning machine, they may put any number in, but the only properties that will change are y and x, not m.
The function will remain y = 2x. Any number could go in place of x, and multiplying x by 2 will give you the y. As long as you have a different value for x, the y will never be the same.
3. So now we have an understanding of what it means, we see that we have been given an x value to insert; an input.
A more practical example could be someting with money. This won't be entirely realistic, because we are dealing with a fraction of a number and another large number.
4. I decided to go with flour. I wanted the 200 to represent pennies, or cents. Before I landed on this, I looked up the cost of flour per pound. I found that the average is .43 dollars, which isn't terribly close to two dollars. But maybe the flour is high quality, so we can stick with that.
5. Seeing that this equation, y=200x, means we are charging 200 cents, or two dollars, we can write a problem from here.
Sylvia is in charge of selling home-harvested flour from an organic farm. She charges two dollars per pound of flower. Today, her next-door neighbors hope to buy a ninth of pound of flour, and they insist on paying with pennies. How many pennies do they need to pay for their order?

A bird was perched on a tree at a height of 19 feet. The bird then saw food on a branch below and dropped down 7 1/2 feet. What is the current height of the bird?
Answer:
11 1/2 feet
Step-by-step explanation:
You simply subtract 19 and 7 1/2 because the bird dropped down which means it is closer to the ground, therefore, subtracting its original height at 19 feet. Hope that helped.
Answer:
19-7.5 = 11.5 or 11 and 1/2 or 23/2

What is this number in standard form?
(7×100)+(4×1100)+(8×11,000)
Answer:
Step-by-step explanation:
factor out 100
100[7 + (4 * 11) + (8 * 110)]
100[7 + 44 + 880]
100 (931)
= 93100
standard form is 9.31 * 10^4
The standard form for the number (7×100)+(4×1100)+(8×11,000) is, 9.31×10⁴
What is the standard form of a number?The standard form for a number is a method by which we write number in a format like b×10ˣ. The value of b should be in between 0 to 10.
Given Number,
⇒ (7×100)+(4×1100)+(8×11,000)
by taking 100 common from all the three terms,
⇒ 100[ 7+ (4×11) + (8×110) ]
⇒ 100[7+44+880]
⇒ 100×931
⇒ 9.31×10⁴
Hence, The number can be written as, 1.39×10⁴

Answer:
A
Step-by-step explanation:
Answer:
C. The mean will increase, and the median will stay the same.Step-by-step explanation:
We know Adam's high score was originally 250, but increased to 290. This would most likely affect the mean since the average mean before Adam received a high score of 290, would have been around 180-220.
We can prove this by hypothetically plugging in 220 for the other three players and 250 for Adam's orginal high score. To find the mean add up the total scores and divided them by four (number of people).
mean (maximum total score) = [tex]\frac{220 + 220 + 220 + 250}{4}[/tex]= 227.5
Then we can plug in Adam's high score of 290 that he late receives.
affected mean (maximum total score) = [tex]\frac{220+220+220+290}{4}[/tex] = 237.5
As you can see, the mean of the maximum total scores is increased by 10.
Now for the median.
The order of the numbers from least to greatest is:
Original- 220, 220, 220, 250 - median = 220
After- 220, 220, 220, 290 = 220
So, the median stayed as 220 and did not change.

Find the exact area of circumference of a circle whose diameter is 8 meters. Show your work
Answer:
Circumference: 25.12
Step-by-step explanation:
Circumference = 2[tex]\pi r[/tex] or [tex]\pi d[/tex]. ( r stands for radius and d for diameter) Since pi is 3.14, 8 times 3.14 is 25.12.
3.14

(If you mean area of the circle its 50.24, circumference times 2)
Answer: 50.24
Step-by-step explanation: The circumference formula is pi (3.14) times diameter, in your case 8.
3.14 x 8 = 25.12
