What is an inequality to compare the temperatures of Mercury and Mars.
Answer:
Mercury > Mars
Step-by-step explanation:
Mercury orbits closer to the sun than Mars, so it has a higher surface temperature.
A farmer is enclosing a square area for his pigs as shown below. Use the formula A = s to the second power to find the area of the pig pen.
The area of the given figure that is mentioned is 64.
A square has congruent angles on each side. The square's area is thus equal to its square divided by its side length.
Let a represent the square's side length. The area of the square will be calculated as:
Area of the square = a² square units
The side provided is 8 ft
The area will be
= a²
= 8²
=64

Step-by-step explanation:
Subtract: 2 - 4 = -2
Multiple: -5 * the result of step No. 1 = -5 * (-2) = 10
Divide: the result of step No. 2 : 2 = 10 : 2 = 5
Add: 5 + the result of step No. 3 = 5 + 5 = 10
Multiple: the result of step No. 4 * 4 = 10 * 4 = 40

You spin each spinner once. You get $50 if you spin a 2 and a vowel. You get $25 if you spin a 2 and a consonant. You get $5 if you spin a 1 and a vowel. Everything else earns $0. What is the expected value of this game?
$8.75
$12.50
$80
$10.25
The expected value of the game is $8.75.
----------------------
The expected value is the sum of each outcome multiplied by it's probability.A probability is the number of desired outcomes divided by the number of total outcomes.The probability of spinning a 2 and a vowel is: [tex]\frac{1}{4} \times \frac{2}{8} = \frac{2}{32}[/tex].Thus, [tex]\frac{2}{32}[/tex] probability of getting $50.The probability of spinning 2 and a consonant is: [tex]\frac{1}{4} \times \frac{6}{8} = \frac{6}{32}[/tex]Thus, [tex]\frac{6}{32}[/tex] probability of getting $25.The probability of spinning 1 and a vowel is: [tex]\frac{3}{4} \times \frac{2}{8} = \frac{6}{32}[/tex].Thus, [tex]\frac{6}{32}[/tex] probability of getting $5.
32 - (6 + 6 + 2) = 18, thus, [tex]\frac{18}{32}[/tex] probability of earning $0.
The expected value is:
[tex]E = \frac{2}{32}(50) + \frac{6}{32}(25) + \frac{6}{32}(5) + \frac{18}{32}(0)[/tex]
[tex]E = \frac{100 + 150 + 30}{32}[/tex]
[tex]E = \frac{280}{32}[/tex]
[tex]E = 8.75[/tex]
The expected value of this game is of $8.75.

y=−3x−1
y = 3x + 1
y=−13x−1

9514 1404 393
Answer:
y = −3x −1
Step-by-step explanation:
The slope of the line between the two given points (-1, 2) and (1, -4) can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (-4 -2)/(1 -(-1)) = -6/2 = -3
The slope is the coefficient of x in the slope-intercept equation for a line. Only one answer choice shows a slope of -3:
y = -3x -1
_____
Additional comment
If you plot the given points and draw a line through them, you see that the y-intercept is -1. Or, you can use this equation to find the y-intercept from one of the points.
b = y - mx
b = 2 -(-3)(-1) = 2 -3 = -1
Now you know m=-3 and b=-1, so you can fill in the slope-intercept form equation:
y = mx +b
y = -3x -1
Answer:
y = −3x −1

2x+10y=20 and passes through (2,3)
Answer:
No, it doesn't pass throughStep-by-step explanation:
As, if we put the value (2,3) in the equation then,
2x + 10y = 20
=> 2(2) + 10(3) = 20
=> 4 + 30 = 20
=> 34 ≠ 20
Hence,
2x+10y=20 does not pass through (2,3)

Step-by-step explanation:
the room has a rug right in the middle of a room. The rug is 3m by 4 m and it is 2 m away from all the surrounding walls. Calculate the area of the room.
Technically it should say the area of the floor of the room but whatever
Also all things done assuming "room" means "floor" and that the rug isn't suspended in midair in the middle of the 3-D room
Answer:
[tex]56~m^2[/tex]
Step-by-step explanation:
If the room is 2 meters away from the rug top and bottom, the room is an extra 4 meters bigger than the rug in width. Likewise for sideways.
WLOG let the rug have a length of 3 and a width of 4(doesn't matter which number goes where). Then, the room has dimensions of [tex](3+4)[/tex] by [tex](4+4)[/tex], which equals 7 by 8 meters.
Therefore, the area is [tex]7*8=\boxed{56~m^2}[/tex]

The length of each side of a square is
represented by 2x - 1. Represent the
perimeter of the square.
Answer:
Perimeter = 4(2x - 1)
Step-by-step explanation:
Since the Perimeter of a square is 4L, it would be,
(2x - 1) + (2x - 1) + (2x - 1) + (2x - 1) which could also be shortened to 4(2x - 1)
Answer:
P = 4(2x - 1)
Step-by-step explanation:
Given that the side of each square is 2x - 1:
The formula for finding the perimeter of a square is:
P = 4s
where s represents the side of a square.
Substitute the given value for s into the perimeter formula:
s = 2x - 1
P = 4(2x - 1)
Therefore, the perimeter of the square is 4(2x - 1).
