Answer:
21 matches
Step-by-step explanation:
This is a combination problem where we have to select two member out of 7 members
So we want calculation of 7C2
7C2 = 7!/[(2!)(7-2)!]
(7*6*5*4*3*2*1)/[(2*1) *(5*4*3*2*1]
(7*6)/2 ~ Note everything that easily cancels here!
42/2
21 matches
Answer:
x = 19°
y = 31°

y = 31
this is probably wrong but i got 25.2
Answer: The quotient = 10
Step-by-step explanation: A quotient is the result you get when a number is used to divide another number. e . g.
6¹/₄ ÷ ⁵/₈ ( where 5/8 is the divisor )
First convert 6¹/₄ to improper fraction
= 25/4 ÷ 5/8
= 25/4 × 5/8
= 10
The quotient = 10.
NOTE: The 5/8 changed to 8/5 because when dividing fractions, immediately you applied the multiplication symbol, the denominator of the divisor becomes the numerator and vice versa
