What is the average of 31.8, 43.8, 29.2, 31.0, and 53.8?
Answer:
37.92
Step-by-step explanation:
To find the average of something add all of the numbers and then divide by how many numbers there are
31.8 + 43.8 + 29.2 + 31 + 53.8 = 189.6
189.6 ÷ 5 = 37.92
Answer:
37.92
Step-by-step explanation:
31.8 + 43.8 + 29.2 + 31 + 53.8 = 189.6
189.6 ÷ 5 = 37.92

What is the slope of this line? Enter your answer as a fraction in the simplest term in the box.
Answer:
-1/1
Step-by-step explanation:
The slope of a line is always the rise over run where rise is up or down(y axis) and the run is side to side(x-axis). Then, if the line is going up, your answer will be negative. So, using the points given, you can tell that the line is moving 2 units down while also moving 2 units to the left. Another way to calculate this is y2-y1 over(/) x2-x1, the y equals your y coordinates, x equals your x coordinants,d the 1 and 2 represent which points. Whichever point you use, you have to use the same coordinants fr the same value. For example, if you took the points (-2,0) and (0,-2) and you used (0,-2) as your second value, you can enter those into the formula.
(-2)-(0) / (0)-(-2) = -2 / 2
the denominater is a possitive two because, when you subtract a negative number, that number becomes positive and you now add it due to the distributive property. 0-(1)(-2) = -2 x -1 = 2

A certain computer can do 250,000 calculations per minute. How many calculations can it do in 0.15 seconds? 37,500
You will get brainliest if you get this question correct. I really need the right answer.
Answer:
625
Step-by-step explanation:
1 minute= 60 second= 60.00 seconds
-------------------------------------
From the information given, we can make this equation:
[tex]\frac{0.15}{60.00} =\frac{x}{250,000}[/tex]
Now all we need to do to find the answer is to solve for x.
-------------------------------------
Cross Multiplication:
[tex]\frac{0.15}{60.00} =\frac{x}{250,000}[/tex]
0.15*250,000=60x
37,500=60x
÷60 ÷60
625=x
x=625
In conclusion:
The computer can do 625 calculations in 0.15 seconds.

thanks guys I know you'll come through!!!!!!!
Answer:
v = [tex]\frac{m}{D}[/tex]
Step-by-step explanation:
Rewrite the equation as [tex]\frac{m}{v}[/tex] = D
[tex]\frac{m}{v}[/tex] = D
Solve for v.
v = [tex]\frac{m}{D}[/tex]

Analise
Benito
Charlie
Dariya
Answer:
Benito's line has a slope of three
Step-by-step explanation:
Slope can be determined by the rate of change. Because Benito's first point is 0,1 that means that x = 0 and y = -1. Benito's second point is 1,2 which means that x = 1 and y = 2. To determine the slope, you need to look at the change of y. We can see that y=-1 in the first point, and y=2 in the second point. This is an increase of three, which means that Benito's line has a slope of three.
Answer: Benito:On a coordinate plane, a line goes through points
(0, negative 1) and (1, 2).

3x+8(2x - 6) = 2 + 14x
Answer:
x=10
Step-by-step explanation:
Simplifying 3x + 8(2x + -6) = 2 + 14x
Reorder the terms: 3x + 8(-6 + 2x) = 2 + 14x 3x + (-6 * 8 + 2x * 8) = 2 + 14x 3x + (-48 + 16x) = 2 + 14x
Reorder the terms: -48 + 3x + 16x = 2 + 14x
Combine like terms: 3x + 16x = 19x -48 + 19x = 2 + 14x
Solving -48 + 19x = 2 + 14x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-14x' to each side of the equation. -48 + 19x + -14x = 2 + 14x + -14x Combine like terms: 19x + -14x = 5x -48 + 5x = 2 + 14x + -14x
Combine like terms: 14x + -14x = 0 -48 + 5x = 2 + 0 -48 + 5x = 2
Add '48' to each side of the equation. -48 + 48 + 5x = 2 + 48
Combine like terms: -48 + 48 = 0 0 + 5x = 2 + 48 5x = 2 + 48
Combine like terms: 2 + 48 = 50 5x = 50
Divide each side by '5'. x = 10
Simplifying x = 10
