Answer:
x^2+1/x^2
(x+1/x)^2 = x^2+1/x^2 +2
(5)^2 = x^2+1/x^2 + 2

Please help! A hat has the following marbles in it: 5 gray, 3 red, 6 white, 2 yellow and 4 green.
What is the probability of picking a gray marble, replacing the marble in the hat, and then picking a yellow marble?
NO LINKS!
Answer:
1/40
Step-by-step explanation:
Probability: (number of ways to achieve the desired result / number of possible results)
For example, if we want a coin to land on heads:
We know there is one way for it to land on heads and two possible outcomes. Thus, the possibility of flipping a head is 1/2.
Using this, we know that there are 5 grey marbles (the desired result) and there are (5 + 3 + 6 + 2 + 4) total possible outcomes. The probability of drawing a grey marble is then:
5 / (5 + 3 + 6 + 2 + 4) =
5/20 =
1/4
We also know that there are 2 yellow marbles, so the probability of drawing one would be: 2 / 20 = 1/10
To find the probability of both of these events happening right after each other, multiply the probability of them each happening together.
1/4 * 1/10 = 1/40 chance of picking a grey marble and then a yellow marble.

Step-by-step explanation:
In coordinates, the x-value appears first then the y-value. This means coordinates are set up like, (x,y). So, to solve find the coordinates whose values match one pair of values on the table. Option A has x=4 and y=2. In the last row of the table, you can see the same values with x=4 and y=2. Therefore, A is correct.

Pyramids A and B are similar. Pyramid A has a height of 9 inches, and Pyramid B
has a height of 27 inches. Pyramid A has a volume of 304 in'. What is the volume
of Pyramid B?
Answer:
V = 8208 cu. in.
Step-by-step explanation:
The ratio of the volumes is equal to the ratio of the cubes of the heights.
Let V = vol. of pyramid B
[tex]\frac{27^{3} }{9^{3} } = \frac{V}{304}[/tex]
[tex]V = \frac{27^{3}*304 }{9^{3} }[/tex]

Dominic used the equation below to find d, the amount in dollars he would spend on gasoline to drive a distance of m miles.
Based on this equation, how much would Dominic spend on gasoline to drive a distance of 180 miles?
Answer:
Dominic used the equation below to find d, the amount in dollars he would spend on gasoline
to drive a distance of m miles.
d= m/25 (3.5)
Based on this equation, how much would Dominic spend on gasoline to drive a distance of
180 miles?
A $25.20
B $21.00
C $24.50
D $28.00
Step-by-step explanation:
The cost of Dominic spend on gasoline to drive a distance of 180 miles is,
⇒ d = 25.2
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Dominic used the equation below to find d, the amount in dollars he would spend on gasoline to drive a distance of m miles.
⇒ d = m / 25 (3.5)
Hence, The cost of Dominic spend on gasoline to drive a distance of 180 miles is,
⇒ d = m / 25 (3.5)
⇒ d = 180 / 25 (3.5)
⇒ d = 25.2
Thus, The cost of Dominic spend on gasoline to drive a distance of 180 miles is,
⇒ d = 25.2

Which of these points lies on the graph of the equation x − 12 = y?
Answer: (4, 8)
Step-by-step explanation:
(4,8)
The points that lie on the graph of equation x − 12 = y are:
(-2, -14)
(0, -12)
(5, -7)
(12, 0)

What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The given equation is x − 12 = y. To check which point lies on this graph, we can substitute the x and y values of each point into the equation and see if it is satisfied.
Let's check each point:
(-2, -14)
Substituting x = -2 and y = -14 into the equation, we get:
-2 - 12 = -14
-14 = -14
This point satisfies the equation.
(0, -12)
Substituting x = 0 and y = -12 into the equation, we get:
0 - 12 = -12
-12 = -12
This point satisfies the equation.
(5, -7)
Substituting x = 5 and y = -7 into the equation, we get:
5 - 12 = -7
-7 = -7
This point satisfies the equation.
(12, 0)
Substituting x = 12 and y = 0 into the equation, we get:
12 - 12 = 0
0 = 0
This point satisfies the equation.
(15, 3)
Substituting x = 15 and y = 3 into the equation, we get:
15 - 12 = 3
3 = 3
This point satisfies the equation.
Therefore,
All the given points lie on the graph of equation x − 12 = y.

Step-by-step explanation:
[tex]\pi \times diameter \\ = \pi \times 18[/tex]
Answer: 56.52
Step-by-step explanation: Circumference is found by using 2πr. Since diameter is twice of radius, this formula can also be used as C = πd. So the circumference will be 18 * 3.14 (which is approximate for π). This gives us the answer of 56.52.

Alexis has a wooden box that is shaped like a rectangular prism. The box measures 8 in. Wide, 9 in. Long, and 4 in. Tall on the outside. The wood used to make the box is 1/2 in. Thick. What is the inside volume of the box? A. 144 in. Cubed B. 168 in. Cubed C. 223 in. Cubed D. 288 in. Cubed Pls show work
Answer:
B. 168 in. Cubed
Step-by-step explanation:
Given that
The box measures 8 in. Wide, 9 in. Long, and 4 in. Tall on the outside.
And, the wood be used to make the box is 1 ÷2 in
We need to find out the inside volume of the box
As we know that
Volume = (length)(width)(height)
= (8 - 0.5 × 2) (9 - 0.5 × 2 ) (4 - 0.5 × 2)
= 7 × 8 × 3
= 168 cubic inches
hence, the second option is correct
find the surface area of the figure below
Answer:
310.8m²
Step-by-step explanation:
GIVEN :-
Diameter = 9m ⇒ Radius (r) = 9/2 = 4.5mSlant height (l) = 13mTO FIND :-
Surface area of the whole figure.FORMULAES TO KNOW BEFORE SOLVING :-
Curved surface area of cone = [tex]\pi rl[/tex] (where r = radius & l = slant height)Curved surface area of hemisphere = [tex]2\pi r^2[/tex] (where r = radius)PROCEDURE :-
In the figure , the cone is mounted on a hemisphere.
⇒ Radius of cone = Radius of hemisphere = 4.5m
Total surface area of the figure = Curved surface area of both cone & hemisphere.
⇒
Curved surface area of cone = [tex]\pi rl = 3.14 \times 4.5 \times 13 = 183.69m^2[/tex] ≈ 183.7m²Curved surface area of hemisphere = [tex]2\pi r^2 = 2 \times 3.14 \times (4.5)^2 = 127.17m^2[/tex] ≈ 127.1m²∴ Total surface area = 183.7 + 127.1 = 310.8m²
