Step-by-step explanation:
because one angle is 90° and also two sides of the triangle are equal
The given triangle is Right angled triangle and Isosceles triangle.
What is triangle ?
Triangle is a two dimensional shape having three side and sum of all angles is equals to [tex]360^0[/tex].
We have,
A triangle with an angle of [tex]90^0[/tex] and two equal sides.
So,
We know that,
When a triangle have any angle equals to [tex]90^0[/tex] then it is Right angled triangle.
Now,
When a triangle have any two sides equal then it is Isosceles triangle.
So,
From the above mentioned statements we can say that triangle is Right angled and Isosceles triangle.
Hence, we can say that the given triangle is Right angled triangle, Isosceles triangle.

15x + 3 = 50
Answers
x = 3.133
Step-by-step explanation:
15x + 3 = 50
15x = 50 - 3
15x = 47
x = 47/15
x = 3.133
Hope it helps you!!Hello.
First, let's subtract 3 from both sides.
15x+3-3=50-3
15x=47
Now, in order to figure out what x equals, we need to divide both sides by 15:
[tex]\displaystyle\frac{15x}{15} =\frac{47}{15}[/tex]
[tex]x=\displaystyle\frac{47}{15}[/tex]
And we're done!
I hope it helps.

There is a spinner with 15 equal areas, numbered 1 through 15. If the spinner is spun one time, what is the probability that the result is a multiple of 5 and a multiple of 3?
Answers
Answer:
6.67%
Step-by-step explanation:
Find the amount of numbers that are multiples of 3 and 5
multiples of 3 = 3, 6, 9, 12, 15
multiples of 5 = 5, 10, 15
only 15 overlaps between these two groups, so it is one number
the total number of available numbers is 15
1/15 = 0.0667
multiply this by 100 to get a percentage
0.0667 * 100 = 6.67%

find the value of x
Answers
Answer:
x= 11
Step-by-step explanation:
=> 8x+5x+37 = 180° { angle sum property }
=> 13x +37 = 180°
=> 13x = 180-37
=> 13x = 143
=> x = 143/13
=> x= 11
The required value of x in the given triangle is 11, for the triangle
The sum of angles 8x, 5x, and 37 degrees is equal to 180 degrees (using the angle sum property).
Adding 8x and 5x together gives 13x, so the equation becomes :
13x + 37 = 180 degrees.
Subtracting 37 from both sides of the equation gives:
13x = 180 - 37.
Simplifying the right side gives:
13x = 143.
To solve for x, we divide both sides of the equation by 13, resulting in:
x = 143/13.
Finally, simplifying the fraction gives:
x = 11.
Thus, the required value of x in the given triangle is 11, for the triangle.

[tex]\displaystyle \frac{81\, p^{6}\, q^{2}}{3\, p^{2} \, q^{5}} = \frac{27\, p^{4}}{q^{3}}[/tex].
Step-by-step explanation:
Make use of the fact that for any [tex]x \ne 0[/tex] and integer [tex]n[/tex]:
[tex]\displaystyle \frac{1}{x^{n}} = x^{-n}[/tex].
For example, in this question:
[tex]\displaystyle \frac{1}{p^{2}} = p^{-2}[/tex].
[tex]\displaystyle \frac{1}{q^{5}} = q^{-5}[/tex].
Thus, the original expression would be equivalent to:

Also make use of the fact that for any [tex]x \ne 0[/tex], integer [tex]m[/tex], and integer [tex]n[/tex]:
[tex]x^{m}\, x^{n} = x^{m + n}[/tex].
Thus:

Problem 1
Answer: Choice A) 1/3-------------------
Explanation:
The notation "P(tune-ups | AC repair)" is the same as saying "P(tune-ups given AC repair)".
The "given" means we only focus on the "AC repair" circle.
Add up the numbers in that circle to get: 1+3+2+0 = 6
There are 6 ASE certified mechanics that can do AC repair.
Of those 6 people, only 2+0 = 2 can do engine tune-ups. Note I added the values in the "AC repair" and "tune-ups" overlapped region.
Therefore, we get the probability 2/6 = 1/3
==========================================================
Problem 2
Answer: B) 2/3-------------------
Explanation:
First, we'll add the numbers found in either the "brakes" or "tune-ups" circles.
4+1+2+2+3+0 = 12
There are 12 mechanics that can handle brakes or tune-ups or both.
Now add up all of the numbers shown regardless of their location. We have 4+1+3+2+2+0+3+3 = 18 mechanics total.
So,
m = number who can do brakes or tune-ups or both
m = 12
n = number of mechanics total
n = 18
And,
P(brakes or tune-ups) = m/n
P(brakes or tune-ups) = 12/18
P(brakes or tune-ups) = (6*2)/(6*3)
P(brakes or tune-ups) = 2/3

Volume is the amount of space occupied by a three dimensional object or figure.
The volume of a cone is given by:
Volume = (1/3) * π * radius² * height = (1/3) * π * (4²) * 12 = 201.1 in³
The volume of a cylinder is given by:
Volume = π * radius² * height = π * (3²) * 8 = 226.2 in³
The difference in volume = 226.2 - 201.1 = 25.1 in³

You could start off with 9*8*7 because you want to work your way down and it doesn't matter which order but just the number of people in each group. 9*8*7 is one group, 6*5*4 is the second group and 3*2*1 is the third group. Now, you want to take each of those equations and divide them by 3!. You do this because there are 3 teams and 9 people are being distributed between them.
9*8*7 6*5*4 3*2*1
-------- = 84 ----------- =20 and ----------- =1
