0.5 ft of snow melts to 2inches of H2o. To how many inches will 4.5 ft of snow melt?
Answer:
4.5 feet of snow = 27 inches H2o. Please read the explanation for better details
Step-by-step explanation:
if 0.5 feet of snow melts into 2 inches of water, then that means that 6 inches of snow melts into 2 inches of water. This means that for every 2 inches of snow you melt, it will become 1 inch of water. If 4.5 ft = 54 inches, you simply divide by 2, getting your answer of 27 inches of snow. Hope this helps! :)
Find the slope of the line that passes through the ordered pairs (-2,8) and (-9,19)
Answer:
slope: -11/7
Step-by-step explanation:
Slope is equal to the change in yy over the change in xx, or rise over run.
m=change in ychange in xm=change in ychange in x
The change in xx is equal to the difference in x-coordinates (also called run), and the change in yy is equal to the difference in y-coordinates (also called rise).
m=y2−y1x2−x1m=y2-y1x2-x1
Substitute in the values of xx and yy into the equation to find the slope.
m=19−(8)−9−(−2)m=19-(8)-9-(-2)
Simplify.
m=−11/7
Answer:
[tex]m=-1\frac{4}{7}[/tex]
Step-by-step explanation:
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}\\\\\left(x_1,\:y_1\right)=\left(-2,\:8\right),\:\\\left(x_2,\:y_2\right)=\left(-9,\:19\right)\\\\m=\frac{19-8}{-9-\left(-2\right)}\\\\m=\frac{11}{-9+2}\\\\m=\frac{11}{-7} \\\\m=-\frac{11}{7}\\\\m=-1\frac{4}{7}[/tex]

Alicia runs for exercist. If Alicia runs 8 miles in 6 days, how many days does it take her to run 36 miles? A 32 b 48 c 24 d 27
Answer:
It takes 27 days
Step-by-step explanation:
We will cross multiply
8/36 = 6/x
216= 8x --- next we will isolate our variable x, therefore you'll divide both sides by 8
216/8 = 8x/8
x = 27
(YOU WILL BE MARKED BRAINLIEST IF YOU WRITE A SHORT STORY FOR THIS MATH PROBLEM!!)
Write a short story that could represent this math problem.
Answer:
Once upon a time a troll was walking down a deep dark hallway, there was no light anywhere that he could see and he was starting to get scared of what could happen to him. But then out of the blue he saw something, something was would change his life forever, he saw a pigeon. Now you might think "Oh, a pigeon, how could that have changed his life?' Now the answer is kind of mundane but is deeper than you might think. The simple answer as to why the pigeon would change his life is because it gave the troll hope, hope that there is an exit. You see, the troll thought if the pigeon found there way into this pitch black hallway, then there must be a way in and hence a way out.
Now listen here, there's something that I wasn't telling you at the beginning of the story about the pigeon, the pigeon was also glowing. This is very useful obviously because it gave the troll some kind of light. Again, it gave the troll hope. Now, being a troll you might think that he would just snatch the pigeon and hold it for light, but this troll wasn't like other trolls, he had the capability to think before he used brute force to change something. So what the troll though was "If I just follow the pigeon then it might lead me to the exit because they have natural navigation in their brains"
Let's skip a while into the future, the troll followed and followed the pigeon for what felt like days, but in reality it was more like 3 hours. But then, the troll saw something that he thought he would never see again; sun light. As soon as the troll saw this, he started running and running towards the light, but as fast as he was running, the light seemed to get farther and farther away from him, then... POOF the troll was gone...
The troll found himself in a very lit up room, almost pure white all around him, which scorched his eyes because he was just in a pitch black room for hours. His ears were ringing and he was in pain, after a while all of that stopped, he was able to see clearly, he felt great, and his ears stopped ringing. What he saw was a very tall thin figure looking down at him from a room of pure white. The figure bent their neck and got right in the trolls face. The figure brought his left hand up to the trolls face, right next to his ear and snapped. The sound of a monstrous click sound right in the trolls ears hurt. The troll jumped back in fear but as soon as the click happened he saw a thing in his vision, a thing he new wasn't actually in the real world as it seemed to follow his eyes where ever he looked. It was, now i know this might sound stupid, I'm not here to imagine a story, I'm simply here to reenact the story of the troll. What he saw was a math problem, a grid was in his vision. It was a 4 by 6 grid.
The tall shadow figure was now back where the troll saw him originally, he was no longer bent and he seemed to not have arms anymore, just a tall dark figure with a cloak. The troll then began to hear a voice which seemed to come from everywhere. It was a deep voice that was very muffled, it said "Do this math problem and go back to your world. Get it correct and everything will go back to normal, but fail; and I'll have your soul" The troll was about to have an adventure of a lifetime...

Cameron wants to buy a skateboard. he has $89, Which is $17 more than he needs. Which equation can be used to determine how much the skateboard costs
Answer:
The answer to this question is $72. The equation is x + 17 = 89
Step-by-step explanation:
Equation: x + 17 = 89
Cameron has $89 so 89 would go behind the equal sign.
He has 17 dollars more than he needs. Whenever more is used that usually indicates that it will be a plus sign. So we will do + 17 = 89.
Finally we need to add the x to complete the equation. This will be shown as x + 17 = 89.
If you solve this equation it will equal x = 72.
If this helped you please subscribe to The Game Rater. Thank you.
Answer:
89-17
Step-by-step explanation:
To find how much Cameron’s skateboard costs you need to take away 17 from your starting amount as you have more. Meaning we subtract the 17 to find how much the skateboard costs.

A particular fruitâs weights are normally distributed, with a mean of 598 grams and a standard deviation of 6 grams. The heaviest 8% of fruits weigh more than how many grams? Give your answer to the nearest gram.
Answer:
The 8% of the fruit weigh more than [tex]x=606.43 \ g[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 598 \ g[/tex]
The standard deviation is [tex]\sigma = 6 \ g[/tex]
Generally the 8% is mathematically represented as
[tex]P(X > x) = 0.08[/tex]
=> [tex]P(X > x) = P ( \frac{X - \mu}{\sigma }>\frac{x - 598}{6} )=0.08[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
[tex]P(X > x) = P ( Z >\frac{x - 598}{6} )=0.08[/tex]
From the normal distribution table the critical value corresponding area representing 0.08 towards the right tail of the curve is
[tex]z = 1.405[/tex]
So
[tex]\frac{x- 598}{6} = 1.405[/tex]
=> [tex]x=606.43 \ g[/tex]

When the question asks for rate of growth in a linear equation, we are going to look for slope. Slope formula is (y2-y1)/(x2-x1). We are given the points (2,5) and (5,8).
Now we can plug them into our formula:
(5-8)/(2-5)
-3/-3

write the coordinates of the vertices after a reflection over the line x=-2
d(-10,0)
e(-10,2)
f(-5,2
g(-5,0)
Given:
The vertices are d(-10,0), e(-10,2), f(-5,2) and g(-5,0).
To find:
The coordinates of the vertices after reflection over the line x=-2.
Solution:
If figure reflected over the line x=a, then
[tex](x,y)\to (2a-x,y)[/tex]
Here, the figure is reflected over the line x=-2, then
[tex](x,y)\to (2(-2)-x,y)[/tex]
[tex](x,y)\to (-4-x,y)[/tex] ...(i)
Now,
For point d,
[tex](-10,0)\to (-4-(-10),0)[/tex]
[tex](-10,0)\to (-4+10,0)[/tex]
[tex](-10,0)\to (6,0)[/tex]
Similarly,
For point e,
[tex](-10,2)\to (-4-(-10),2)=(6,2)[/tex]
For point f,
[tex](-5,2)\to (-4-(-5),2)=(1,2)[/tex]
For point g,
[tex](-5,0)\to (-4-(-5),0)=(1,0)[/tex]
Therefore, the coordinates of vertices after a reflection over the line x=-2 are d prime (6,0), e prime (6,2), f prime, (1,2) and g prime (1,0).
Explain how the location of the vertex and the direction of the opening (upwards or downwards) affects the domain and range of the quadratic function. Use complete sentences.
Answer:
Following are the solution to this question:
Step-by-step explanation:
Its vertex position, as well as the position of its opening, influence its quadratic function set. Its y-coordinate of its vertex (v) and then all values of current above it are included in scope whenever the direction of openings becomes up therefore, the lowest y-value becomes possible.
It implies the scope is y >=v. If it sets up, then, y-coordinate of its vertex was its highest y value available, from all y-values above too y <= v. The scope of a quadratic function, as it will continue forever to left and right, from the negative to positive infinity.Please help I will brainliest!! Really urgent!!
