Answer:
10 ways
Step-by-step explanation:
Find out the number of ways in which 6 flags can be arranged in a row if 3 red ,2 green, and 3 yellow ?
The above question can be calculated as:
= 6!/(3! × 2! × 3!)
= 720 /(6 × 2 × 6)
= 720/(72)
= 10 ways
ANSWER: -60
EXPLANATION: To solve for (-10) - |(-20) – (+30) |, we need to do:
−10−| −20 − 30|, which equals −10−|−50|. Next, we do −10−50, which is -60.
−10−|−20−30|
= −10−|−50|
= −10−50
= −60
Answer:
3
Step-by-step explanation:
3(1)-2= 1
2(1)+1 = 3
We would find the midpoint by applying the formula for determining the midpoint of a segment which is expressed as
Midpoint = (x1 + x2)/2, (y1 + y2)/2
From the given points,
x1 = 4, y1 = - 5
x2 = 6, y2 = 1
Midpoint = (4 + 6)/2, (- 5 + 1)/2
Midpoint = 10/2, - 4/2
Midpoint = 5, - 2
Answer:a=1 b=5 c=9
Step-by-step explanation:
-7,-3,a,b,c,...... Is the arithmetic sequence
first term=p=-7
Common difference=d=-7-(-3)=-4
a is the 3rd term=-3+4=1
b Is the 4th term=1+4=5
c is the 5th term=5+4=9
Therefore
a is 1
b is 5
c is 9
