The answer is 27
Step-by-step explanation:
(2x + 16) + (x) = 180
step-by-step explanation:
given,
abcd is a quadrilateral inscribed in a circle
angle a is labeled x plus 16, (x + 16)
angle b is labeled x degrees, (x)
angle c is labeled 6x minus 4, (6x – 4)
angle d is labeled 2x plus 16, (2x + 16)
what equation can be used to solve for angle b?
we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.
angle b is opposite angle d
therefore, angle b + angle d = 180
(x) + (2x + 16) = 180
same as (2x + 16) + (x) = 180
You have 8 choices for the third digit (digits 0 - 9 excluding the numbers you chose for the first and second digit). So by the multiplication principle (MP), there are 9*9*8 ways to do this. So there are 648 numbers that are 3 digit numbers and have no repeated digits.
Step-by-step explanation:
36 girls
step-by-step explanation:
the 48 boys is 4 parts of the ratio
divide 48 by 4 to obtain one part of the ratio
[tex]\frac{48}{4}[/tex] = 12 ← 1 part of the ratio
3 parts = 3 × 12 = 36 ← number of girls
