For numbers 15-17, we need to remember that two of a triangle's angles are always acute and the third angle will allow us to classify the triangle based on its angles. now that we know this, let's look at #15. the first two angles listed are acute, and the third is an obtuse angle, therefore it is an obtuse triangle. on #16 we have three acute angles, so it is an acute triangle. #17 has two acute angles and a right angle so it is a right triangle.
on numbers 21-23, we need to know that a triangle with all congruent sides is called equilateral, a triangle with two equal sides is isosceles, and a triangle with no equal sides is called scalene. #21 shows two equal sides so it is an isosceles triangle. #22 has three equal sides so it is an equilateral triangle. #23 has no equal sides so it is scalene. hope this helped! :)
Answer:
Step-by-step explanation:
If you sum everything, you'll get 50 candies. Now you know that 50 candies is 100%.
Now you'll calculate the probability:
12 on 50 : 24.00 %
17 on 50 : 34.00 %
5 on 50 : 10.00 %
6 on 50 : 12.00 %
Hope I was helpful :)
Edit :
12/50 17/50 6/50 5/50
The equivalent expression of 4b+13/2 is (8b+13)/2.
Given an expression be 4b+13/2.
We are required to find the equivalent of the expression 4b+13/2.
Expression is combination of numbers, symbols, fractions, coefficients, determinants, indeterminants. In an expression we do not find any equal to sign. It shows some relationship. In this expression b is the only variable that exists. If we have been given some value of th expression at some point then we can get the value of variable.
The expression is 4b+13/2.
Taking LCM first.
The LCM of any two numbers is basically the value that is evenly divisible by the two given numbers.
=(8b+13)/2
Hence the equivalent expression of 4b+13/2 is (8b+13)/2.

Lets x = width
height = 2x - 4
A = 1/2 b h
63 = 1/2 (x)(2x-4)
126 = 2x^2 - 4x
2(x^2 - 2x - 63) = 0
2(x - 9)(x + 7) = 0
x - 9 = 0; x = 9
x + 7 = 0; x = -7
so width = 9
height = 2(9) - 4 = 18 - 4 = 14
answer
width = 9 in
height = 14 in
