Answer: the height of the tree is 27 feet
Step-by-step explanation: We can set up a proportion comparing the height of each object to the length of the shadow.
h s
h 15 = 18

Cross multiply
10 ⋅ h = 18 ⋅ 15
10 h = 270
Use the multiplicative Inverse

Answer:
$5.30
Step-by-step explanation:
23.85/9=$2.65
2.65*2=$5.30
Answer:
I don't know if this is right but I got $5.30.
Step-by-step explanation:
I did 23.85/9 to get how much each pane is than I multiplied by 2 to get the cost of the 2 new panes.
23.85/9= 2.65
2.65*2 = 5.3

What is the full question?
A bucket contains 6 green rubber balls, 4 red rubber balls, and 8 purple rubber balls. Alex removes 3 rubber balls, without replacement, from the bucket. What is the probability that Alex removes a green ball, red ball, and purple ball in that order?
in total there are 6,4,8 which equals 18 .There are 18 balls in total. but Alex removed 3 so now there are 15 balls. There 3 different colors and 15 balls. So there is a 5% out of 15 that you will get a certain color .To find the probability you need to calculate all the possible outcomes.
G=Green R=Red P=Purple
G,R,P
G,P,R
P,G,R
P,R,G
R,P,G,
R,G,P
There is 6 different outcomes, 15 balls and a 5% chance to get a certain color so if you want to exactly get G,R,P there is a (15 divided by 6) chance to get that order.
(I'm not good at calculating that part.)

A student finds the slope of the line between (14, 1) and (18, 17). She writes [tex]\frac{1-17}{18-14}[/tex]. What mistake did she make?
A. She used y-values where she should have used x-values.
B. She should have added the values, not subtracted them.
C. She mixed up the x- and y-values.
D. She did not keep the order of the points the same in the numerator and the denominator.
Answer:
Step-by-step explanation:
She did not keep the order of the points the same in the numerator and the denominator.
I hope this helps!
...............................................................................................................................................
slope is y2-y1/x2-x1
if this was set up correctly it would be 17 - 1/18 - 14
The student simply switched the places of the y change calculation.
...............................................................................................................................................
The answer is D. She should have used 8-1 as the denominator since she used 17-14 as the numerator.
...............................................................................................................................................
Answer:
The answer is the option D.) she did not keep the order of the points the same in the numerator and the denominator
Step-by-step explanation:
we know that

The student who traveled to states visited new states during a vacation. Does increasing the to change the median? If so, how?
Step-by-step explanation:
The exact question is as follows :
Given - The student who traveled to 3 states visited 6 new states during a vacation.
To find - Does increasing the 3 to 6 change the median? If so, how?
Proof -
Yes,
If we increase the 3 states to 6 states, it changes the median
Because
The median of the first 3 states is the middle state.
For example -
If we have 3 states X, Y, Z
Then the median is the state Y
Now,
The median of 6 states is the average of the 2 middle states.
For example -
If we have 6 states
X, Y, Z, U, V, W
Then
The median is not explicit.
Median is the average of the two middle states, Z and U.
And
Average of Z and U = half of the sum of Z and U.
i.e. (Z + U)/2.
And we can see that,
Median of 3 States is not equal to Median of 6 states
i.e. Y is not equal to (Z + U)/2.
So,
We can say that,
Increasing the state 3 to 6 changes the median.

A triangle has side length measurements of 7 ft., 2 ft., and 5
feet. Can this form a triangle? Explain why or why not.
Answer:
No
Step-by-step explanation:
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.

not greater than 7
Find the VOLUME of the pyramid shown.
Please help me out ! It would be greatly appreciated
Answer:
3 is your base
4 is your height
(this is for the area of the bottom)
3 x 4 = 12
12 divided by 2 = 6 is your area of the bottom
6 x 4(height) = 24
24 divided by 3(times 1/3) = 8

answer: 92
Step-by-step explanation:
These Will add up to 360 in total so b and c our 92 because 92 + 92 + 88 + 88 = 360 Hope that helps!
Step-by-step explanation:
here's your solution
==> 88° + b° = 180°. [ linear pair ]
==> b° = 180° - 88°
==> b° = 92°
b° = c°. [ vertical angle ]
==> c° = 92°

A park charges $45 to enter and $0.75 per game. Write an algebraic expression to represent the total amount paid by a guest.
Answer:
y = 0.75x + 45
Step-by-step explanation:
x would be the amount of games played and y would be the total money spent.
Answer:
y= 0.75x+45
Step-by-step explanation:
y= total amount paid by guest
x = # of games
0.75 x = $0.75 paid per game
45= minimum charge of 45 to enter park

Answer:
CBD is 120 degrees
Step-by-step explanation:
x=30
4x30+30+30=180
Answer: 120°
Step-by-step explanation:
x + 4x + x = 180° (Since the sum of a straight line is 180°)
6x = 180°
x = 30°
To find the angle of 4x, we need to multiply 4 x 30°

243,700,000 in scientific notation
Answer:
Read explanation, you gotta know how
Step-by-step explanation:
Step 1: What I do is pretty much find where you want the dot to be, which in this case is between the 2 and the 4.
Step 2: right now the dot is all the way to the right, so we gotta move it to the left.
Step 3: start moving the dot to where you want it to be (inbetween the 2 and the 4) and make sure to count how many times you move the dot Left, until you reach the point you want it to be.
step 4: now you have the dot where you want it to be, and you counted how many times you moved the do to get there (Should look like this now= 2.437) you dont need the zeros anymore because 2.43700000 is the same as 2.437.
Step 5: add the scientific notation thing which is (Number) x 10^ (the amount of times you moved the dot to the left)
Step 6: now you have the answer which is 2.347 x 10^8 (dont just skip all the explanation to do this, If you learn how you wont need to waste your points asking the same question again.)

PLEASE HELP. Will give 70 points!!! Demonstrate In A Brief Paragraph How The Search To Explain Planetary Orbits Exemplifies The Scientific Method and the use of models.
People firstly believe that the planets move in a circular orbit until Newton came up with his hypothesis by inventing calculus so that we could understood and calculated planetary orbits and their accuracy.
Explanation:
Everyone assumed the planets were perfect circles until Newton came up with an idea. Slowly people would make maps of the orbits that added circles on circles, and they could never really explain about the movement of the planet. They simply say that planets move on circles but they lacked the math to explain or prove it. Then Newton came up with an idea of inventing calculus so that we could understood and calculated planetary orbits and their accuracy.
Firstly people used their observations and say that the orbits looked like circles, then they developed their models and did the math, and proposed their hypothesizes which were wrong, until Newton came along and tried to match a model that used elliptical orbits and invented the math that allowed him to make predictions with it. His model worked for most planets.
However he could not explain about the planet Mercury for instance since it was a very strange orbit. Then after the Einstein's theory of General Relativity he could also explain very deeply about it.
Scientists and Astronomers made hypothesizes that there was another planet orbiting too close to the sun to see with telescopes, called Vulcan, that explained mercury's orbit before Einstein's theory. Then long after we had telescopes which was good enough to see if there was a planet orbiting closer to the sun than mercury.

A television originally cost
$
2660
. It goes on sale at
10
%
off the original price.
How much do you save when you buy the television now?
Saving = $
What does the television cost now?
Cost now = $
Submit Answer
Answer:
You save $266. The television costs $2394.
Step-by-step explanation:
10% off the original price is $266. The television is 10% off, meaning the new price is 90% of the original price. Therefore, you can subtract $2660 - $266 or multiply 90% × $2660.

Determine the length of the diagonal for a TV that has a width of 50 inches and a height of 37 inches. Round ONLY your answer to the nearest inch.
Answer:
62.2 inches
Step-by-step explanation:
a²+b²=c²
Plug in your known variables.
50²+37²
This will equal to 3869
Now you will have 3869 = c²
Square root both sides
√3869 = √c²
62.2 inches ≈ c
