Tyrone is working with two other students to build a border around the school’s triangular garden. Each student brought in one side of the border, but they all used different units to measure the side lengths. The first side is 312 inches long, the second side is 20 feet long, and the third side is 12 yards long. If the measurements need to be in feet, will the three border pieces make a right triangle?
Convert the first side into feet using a proportion.
Answer:
NO, the these three border pieces will not make a right triangle
Step-by-step explanation:
Perform the necessary conversions:
1. 312 in converts to
312 in 1 ft
----------- * ------- = 26 ft
12 in 1
2. 20 ft
3. 12 yd converts to
12 yd 3 ft
------------- * --------- = 36 ft
1 yd 1
So the three different side lengths are 26 ft, 20 ft and 36 ft.
For the three pieces to make a right triangle, these measurements must satisfy the Pythagorean Theorem:
26² + 20² = 36², or 1296
676 + 400 = 1076
The Theorem is NOT satisfied, and so NO, the these three border pieces will not make a right triangle.
Jonathan went to the movies with $48 he earned at his after-school job. The ticket cost $8.75. He spent $7.45 for refreshments. How much money did he have left?
Answer:
8.75+7.45=16.2. 16.2 is equal to $16.20 so 48.00-16.20=31.8. Jonathan had $31.80 left.

What is the volume of the cylinder and i need how you got the answer plz. Thank you
Answer:
471.24 inches is the volume of the cylinder.
Basically, since the diameter of the cylinder is 10 inches the radius will be 5 inches.
The formula to figure out the volume of a cylinder is V=πr2h.
So using that formula the volume of the cylinder is 471.24 inches.

Answer:
125-5x^2
this is the answer
Answer:
-5x^2+125
Step-by-step explanation:
You need to go step-by-step here. I would actually prefer to multiply by 5 at the end, because it's easier that way. (You can multiply the terms in any order you want, though.)
So first, multiply (5-x)(5+x). This is a special product: (a-b)(a+b)=a^2-b^2, so:
(5-x)(5+x)=5^2-x^2=25-x^2
But even if you don't know that special product, you can multiply it out. Rewrite (5-x)(5+x) as 5(5+x)-x(5+x).
5(5+x)-x(5+x)
=25+5x-(5x+x^2)
=25+5x-5x-x^2
=25+0x-x^2
=25-x^2
As you can see, the result is the same regardless of you get it. Now multiply that by 5 to get 125-5x^2, or in standard form, -5x^2+125.
Hope I could help you!

Here is the first one
A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 6 inches.
Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 6) would represent a height of 6 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)
Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)
Part C: If the rate at which the candle burnt was 0.3 inches per hour instead of 0.5 inches per hour, will the relation continue to be a function? Explain your answer using input and output values. (3 points)
9514 1404 393
Answer:
A. (0, 6), (1, 5.5), (2, 5), (3, 4.5), (4, 4), (5, 3.5)
B. is a function
C. is a function
Step-by-step explanation:
Both relations are functions.
A relation is NOT a function if the same input value maps to two different output values. Virtually any relation involving time as an input will be single-valued: a measure can only have one value at any given time (ignoring quantum physics).
__
A: If height decreases 1/2 inch per hour, then some ordered pairs could be ...
(hours, inches) = (0, 6), (1, 5.5), (2, 5), (3, 4.5), (4, 4), (5, 3.5)
For each additional hour, 0.5 inches was subtracted from height.
__
B: There is only one output for each input, so the relation is a function.
__
C: Yes, the relation is still a function. There is still only one output value for each input value.

Answer:it a
Step-by-step explanation:
the answer is c because the definition of multiplicative inverse is :
In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/x or x−1, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a/b is b/a. For the multiplicative inverse of a real number, divide 1 by the number.
Brad paid for a book that cost $13.40 with a $20 bill. What is the least combination of coins and bills that can be used to make his change? What are two other different combinations of coins and bills that can be used to make the change?
Answer:
First combination: One $5 bill, one $1 bill, two quarters and one dime.
Second combination: One $5 bill, one $1 bill, two quarters and two nickles.
Step-by-step explanation:
I highly suggest reading it to make sure you understand it
Okay so for this one you're going to want to do 20.00-13.40. The answer to that is 6.60
So we have to work with $6.60
Now lets think of the obvious/easiest.
A $5 bill is going to be our best friend in this.
We have to do
6.60-5.00=x
(Don't freak out about x, it's just our place marker!!)
The reason we do 5.00 is because that's what $5 is.
So let's solve now.
6.60-5.00=1.60
So x=1.60
But you don't have to worry about x, I'm just explaining it from before.
So we have to keep in mind that we used one $5 bill. Now let's use one $1 dollar bill.
1.60-1.00=0.60
So now we only have to figure out how to get 60 cents from any of the coins.
A quarter is 25 cents so lets use two of those
25+25=50
60=50=10
Lets recap on everything we've used so far.
We've used one $5 bill, one $1 bill, and two quarters.
Now we're going to add a dime to the mix.
A dime is worth 10 cents.
So for the first combination we used: One $5 bill, one $1 bill, two quarters and one dime.
Now our second combination is going to be really easy.
We can use almost everything the exact same, we're only going to switch up the dime part.
1 dime = 2 nickles
Nickles are worth 5 cents
So we take out the dime and replace it with two nickles.
So for the second combination we use: One $5 bill, one $1 bill, two quarters and two nickles.
Brooklyn was writing an article for her school paper and read a report that said 2 out of 20 items purchased at a clothing store were returned. The percent of items returned to the clothing store was _______ %
Answer:
10%
Step-by-step explanation:
1/20 = 5/100
5/100 = 5%
1/100 = 1%
2/20 = 10/100
10/100 = 1 x 10 = 10%

what is g if, g + (g + 21) + (2g - 6) = 191
Answer:
g=44
Step-by-step explanation:
(2g+21) + (2g-6)=191
1. Eliminate redundant () :
2g+21+2g-6 =191
2. Subtract numbers:
2g+15+2g=191
Combine like terms:
4g+15=191
4g=176
Divide:
4g/4=146/4
Solve:
g=44

The graph shows the depth, y, in meters, of a shark from the surface of an ocean for a certain amount of time, x, in minutes:
Part A: Describe how you can use similar triangles to explain why the slope of the graph between points A and B is the same as the slope of the graph between points A and C.
Part B: What are the initial value and slope of the graph and what do they represent?
Step-by-step explanation:The slope of AB and BC are the same.
The initial value is 60 m and the slope is 40 m/min.
Step-by-step explanation:
The graph shows the depth, y, in meters, of a shark from the surface of an ocean for a certain amount of time, x, in minutes.
See the graph attached.
Part A : If we consider two right triangles one Δ ABD and Δ BCE, where D(2,100) and E(1,60) points.
Now, those two triangles are similar and hence the slope of line segment AB will be .
Again, the slope of the line segment BC will be
Hence, and the slope of AB and BC are the same. (Answer)
Part B : From the graph, it is clear that the initial value of the graph is 60 m and it represents that initial position of the shark i.e. at t = 0 min, the shark was at a depth of 60 m from the water surface.
The slope of the graph is 40 means the rate of change of distance from the Ocean surface of the shark with respect to time in minutes will be 40 m per min. (Answer)
