A linear function can be used to estimate the decrease in snowfall measured since 1920. The decrease in the annual snowfall has been on average 0.24 inches per year. Let x represent the number of years since 1920, when the measurements began, and let y represent the annual snowfall. The initial measurement in 1920 was 48.6 inches. Using the average change and initial measurement, which is the best estimate of the annual snowfall in the 78th year after records were kept? Round to the nearest hundredth.
Answer:
29.88 inches
Step-by-step explanation:
Equation of a line is given in the form
Where
m is the slope [rate of change, here, rate of decrease]
c is the y-intercept [at 1920, the snowfall]
From the problem, we see that snowfall decreases by 0.24 inches per year, that will make the slope (m) to be -0.24
Also, at 1920, the initial measurement was 48.6 inches of snow, that is the y-intercept (b). Thus, we can write the equation of this line as:
y = mx + b
y = -0.24 x +48.6
To find annual snowfall, 78th year after 1920, we simply plug in 78 into "x" of the equation just found. So:
y = -0.24(78) + 48.6 = 29.88 inches
Answer:
29.88 inches

Answer: The distance in kilometers is equal to the distance in miles multiplied by 1.609344. Since one mile is equal to 1.609344 kilometers, that's the conversion ratio used in the formula. So 5 kilometers is approximately 3.1 miles
Answer: 3.10685
Step-by-step explanation:
Since 1 kilometer is equal to 0.62137 miles, and we have 5 kilometers, we simply multiply 5 by 0.62137 to convert 5 kilometers to miles.

HELP I CANT DO MATH PLEASE
Answer:
A' : (-5, -8)
B' : (-5, -1)
C' : (2, -1)
Step-by-step explanation:
A is (-5, 8), B is (-5, 1), C is (2, 1), and we want to find the points after we reflect the triangle over x.
The first thing to remember is that when points are written like (x, y), the first number, x, is how many units you go right or left and the second number, y, is how many units you go up or down. The second thing to keep in mind is that the x-axis is the horizontal one that runs from left to right.
Now, just think about the information we have: if we want to flip a point like (-5, 8) over the x-axis, all we have to do is make the 8 negative. This is because the 8 is how far up the point is, so to make it flip down over the x-axis, we just change the sign. The -5 does NOT change because it's the x-value, which is how far right/left the point is. Does that make sense?
If we do this for the other two, (-5, 1) becomes (-5, -1) and (2, 1) becomes (2, -1).
(The apostrophe-like symbol the problem uses--like A', B', C'--just denotes that those are the resulting points after the reflection.)

Answer:
B. 21 and 19/25
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
21.76=21.761
Multiply to remove 2 decimal places. Here, you multiply top and bottom by 102 = 100
21.761×100100=2176100
Find the Greatest Common Factor (GCF) of 2176 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 4,
2176÷4100÷4=54425
Simplify the improper fraction,
=211925
In conclusion,
21.76=211925
Answer: B. 21 and 19/25

Serena paid $194.99 for a game system and then bought two equally-priced games. She spent a total of $284.97.
Part A
If p represents the price of one game, which equation represents the situation?
2p – 284.97 = 194.99
2p + 194.99 = 284.97
2p + 284.97 = 194.99
2p – 194.99 = 284.97
Part B
What is the price, p, of one game?
$ ____________
Answer:
Part A is 2p – 194.99 = 284.97
Step-by-step explanation:
the price for one game is 44.99
Which of the following is a pair of similar triangles?
A) Image A (1st Image)
B) Image B (2nd Image)
C) Image C (3rd Image)
D) Image D (4th Image)
Image C for sure.
Sure, both triangles don't show all angles, But if you look at the first triangle in image C, it's just a more stretched out version of the second one. The angles are the same, just one triangle is slightly taller.
Which graph shows the image being rotated 90°?
Answer:
its A

Hey there!
A. 3x5 is 15! However since one of the number is a negetive, we must add a negetive sign to the 15, making it -15!
Remember this: A negetive number times a negetive number is a posititve number, but a negetive number times a positive number is a negetive!
B. 5+-5 is equal to 0, so 3x0 is 0!
C. No matter which way you mutliply it, whether it's -5x3 or 3x-5, the answer will always be -15! (-5)x(3+-3) is: 3+ -3 is 0, so -5 times 0 is the same thing as 5x0, which is still 0!
D. Like I said before, a negetive times a negetive is a positive, so -3x-5 is the same as saying 3x5, which is 15!

5 ( f + 4) = 4 ( f - 6)
f = -44
Hope this helps :)
Answer:
The answer is -44
Step-by-step explanation:
First, you use distributive property on each side.
5xf + 5x4 = 4xf-4x6
5f+20=4f-24
Then you subttract 5f to both sides of the equation.
5f+20=4f-24
-5f -5f
20=-1f-24
Next, you add 24 to both sides of the equation.
20=-1f-24
+24 +24
44=-1f
Finally, you divide -1f from each side of the equation.
44=-1f
/-1f /-1f
Your final answer should be -44=f
or f = -44
