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.
2 + 5 is only equal to 7
not greater than 7

How are finding the volume of a rectangular prism and a triangular prism alike
Answer:
the triangular prism is ⅓ the size of the rectangular prism. they have the same concept equation of:
rectangular prism - length×width×height
triangular prism - ½×length×width×height
they both have to multiply the base and height to find the volume
Answer:
Finding the volume of a rectangular and triangular prism are alike, one way is they use similar formula base x length x height. Another way is They both have rectangle in the prism.

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

a
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.)
Solve the following quadratic by
completing the square.
y = x2 + 10x + 10
Answer:
x = -5 - √15 or x = -5 + √15Step-by-step explanation:
[tex]y = x^2+10x+10\\\\y=x^2+10x+25-25+10\\\\y=(x+5)^2-15\\\\y=0\quad\iff\quad (x+5)^2-15=0\\\\(x+5)^2=15\\\\x+5=\pm\sqrt{15}\\\\x=-5-\sqrt{15}\quad or\quad x= -5+\sqrt{15}[/tex]
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.
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.

The relationship between the number of years (x) that have passed and the population (y) for a small town is shown in the table.
Population Count Per Year
2 3 4
Number of Years (x)
1
5
6
7
8
Population (y)
1,440 1,728 2,074 2,488 2,986 3,583 4,300 5,160
A regression equation for this data is y = 1, 200(1.2).
Answer:
D. 10,699
Step-by-step explanation:
The given data for the Population Count Per Year is presented as follows;
Number of Years (x); 1, 2, 3, 4, 5, 6, 7, 8
[tex]\begin{array}{ccccccccc}Number \ of \ Years \ (x)&1&2&3&4&5&6&7&8\\Population \ (y)&1,440&1,728&2,074&2,488&2,986&3,583&4,300&5,160\end{array}[/tex]The data regression equation is y = 1,200·(1.2)ˣ
Based on the regression equation for the data, the predicted value of the town's population after 12 years is given by substituting x = 12 as follows;
After 12 years, y = 1,200 × (1.2)¹² ≈ 10,699.32
Therefore, the option which is the best prediction is 10,699.

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
