Answer: No, we don't have a right triangle
==========================================================
Explanation:
If a triangle with sides a,b,c makes the equation a^2+b^2 = c^2 true, where c is the longest side, then this triangle is a right triangle. This is the converse of the pythagorean theorem.
Here we have a = 2, b = 5 and c = 7.
So...
a^2+b^2 = c^2
2^2+5^2 = 7^2
4+25 = 49
29 = 49
The last equation is false, so the first equation is false for those a,b,c values. Therefore, we do not have a right triangle.
------------
In contrast, consider the classic 3-4-5 right triangle
a = 3, b = 4 and c = 5 would make a^2+b^2 = c^2 true because 3^2+4^2 = 5^2 is a true equation (both sides lead to 25).

If a vehicle to school and 72 mph how many feet does vehicle travel in one second
Answer:
The vehicle travels 105.6 feet in one second.
Step-by-step explanation:
This question is solved by proportions.
72 mph
One hour has 3600 seconds.
Each mile has 5280 ft.
So in 3600 seconds, the vehicle travels 5280*72 = 380160 feet. In one second, how many feet?
3600 seconds - 380160 feet
1 seconds - x feet
Applying cross multiplication:
[tex]3600x = 380160[/tex]
[tex]x = \frac{380160}{3600}[/tex]
[tex]x = 105.6[/tex]
The vehicle travels 105.6 feet in one second.

Question about decimals
I have a math problem
205.17/713.95
I worked it out all by hand and eventually got to 34.79797241 as the calculator stated. This problem was very time consuming as it took a lot of work to complete. I was wondering if there was a simpler way of cutting my answer short that would also be correct?. I am unable to determine if this number is terminal or repeating as the decimal answer looks repeating with the 7979 but then appears to be terminal with the 241 part. Im assuming this number is terminal? Do I just need to suck it up and do the math or Is there a certain part of the decimal place value it would be appropriate to just stop at?
One more question unrelated to my previous questions.
I originally tried to solve this problem out of (A.) 713.95the divisor /by 205.17 the dividend as I know I am ALWAYS supposed to put the bigger number in the dividend section, but I am curious on how I would go about solving this question the opposite way (B.) with 205.17 as the divisor /by 713.95 as the dividend. I know this is possible as the calculator states
(A.) 713.95/205.17 =3.479797241
(B.) 0.2873730653 (I'm guessing this overwhelmingly long decimal is also terminal?)
Answer:
Both are terminating decimalsStep-by-step explanation:
Answer to your questions:
First of all, both A and B are correct and both quotients are terminating decimals.To find out if the decimal is terminating or not, multiply the quotient by divisor. If you get exactly the same number as dividend, then it is terminating otherwise it is non-terminating.The fraction may have greater numerator than denominator, in this case the quotient will be greater than one.Now regarding simplification. You would be asked to give an answer rounded to some extend. One decimal place, two decimal places, 3 significant numbers etc. For the first operation you would get 34.8 (rounded to nearest tenth). Or you may be asked to have a best estimated result. In this case you would round the initial numbers and find results. 205/714 ≈ 0.29Find a,b,c and d?..........

Answer:
a = 6, b = 12, c = 6, d = 6√3
Step-by-step explanation:
The two triangles are the "special" triangles.
The 45-45-90 triangle has side lengths in the ratios 1 : 1 : √2.
The 30-60-90 triangle has side lengths in the ratios 1 : √3 : 2.
Then ...
c : a : 6√2 = 1 : 1 : √2 ⇒ c = a = 6
and ...
a : d : b = 1 : √3 : 2 ⇒ d = 6√3 and b = 12 . . . (since a=6)
The lengths are ...
a = 6, b = 12, c = 6, d = 6√3
A person of interest was identified by the police. Using three different telecommunication towers,
the police were able to gather the following information about the person's cell phone location.
• The person is 7 miles away from A(4,4.6).
• The person is 5 miles away from B(-3.5, - 3.8).
• The person is 6 miles away from C(-6, 5.5).
Use the information from towers A, B, and C to find the approximate location of the person of
interest.
Answer:
Well since he tracked the person through the communication towers he was able to gather information, with this information we can solve and find out how far this person is.

Answer:
SAS. ( side, angle, side)
in option 2nd
Answer:
False
SAS = This stands for Side Angle Side congruency theorem
Step-by-step explanation:
Question 1.)
If any of the 2 angles of any triangle is congruent to any of the 2 angles of the other triangle, then this would be true. Let's find the measure of ∠R and ∠G:
=> ∠G = 180 - (98 + 30)
∠G = 52
=> ∠R = 180 - (98 + 26)
∠R = 56
Now we know that Angles of ΔHIG are 30, 98, and 52, and Angles of ΔSQR are 26, 98, and 56. 2 angles of 1 triangle are not congruent 2 angles of the other triangle, therefore the triangles aren't congruent.
Question 2.)
SAS congruency is used since an angle and it's 2 adjacent sides are given for each triangle.

Determine the equation of the circle graphed below.
Step-by-step explanation:
radius= √(2+2)²+(0+3)²=√4²+3²=√16+9
=√25=5
the equation is
(x+2)²+(y+3)²=25
or
x²+y²+4x+6y-12 = 0
The perimeter of the
rectangle is 14 m and
the area is 12 m2.
Calculate the length
of the rectangle
diagonal
Answer:
5
Step-by-step explanation:
area of rectangle = l(ength)×w(idth)
perimeter = 2×l + 2×w
diagonal = sqrt(l² + w²) (Pythagoras)
l×w = 12. => l = 12/w
2×l + 2×w = 14
2×12/w + 2×w =14
12/w + w = 7
12 + w² = 7w
w² - 7w + 12 = 0
=> (after a little thinking and trying : what 2 numbers multiply to 12 and add to -7 ? -3 and -4
=> (w-3)×(w-4) = 0
so, we get 2 solutions for w : 3 and 4
that gives us 2 solutions for l : 4 and 3
so, one is 3 and the other 4. it does not matter which is which. length 4 and width 3 produce the same diagonal as length 3 and width 4.
diagonal = sqrt(l² + w²) = sqrt(16 +9) = sqrt(25) = 5
Find the value of x for which ABCD Is a parallelogram:

Solve for (0,2π]
2cos ß * sin ß = cos ß
Given :
An equation, 2cos ß sin ß = cos ß .
To Find :
The value for above equation in (0, 2π ] .
Solution :
Now, 2cos ß sin ß = cos ß
2 sin ß = 1
sin ß = 1/2
We know, sin ß = sin (π/6) or sin ß = sin (5π/6) in ( 0, 2π ] .
Therefore,
[tex]\beta = \dfrac{\pi}{6}\ or\ \beta = \dfrac{5\pi}{6}[/tex]
Hence, this is the required solution.
