Answer:
Y = 27.
Step-by-step explanation:
40 - 13 = 27. If we check our math 13 +27 does equal 40 making the equation correct.
Out of 12 rolls the tail appeared 8 times
So this experimental probability =8/12 = 2/3 (answer c)
Answer:
length : 10 yard
width: 14 yard
Step-by-step explanation:
Let l be the length of the yard.
Since the width is 6 yards less than twice its length, we can say the width is 2l-6.
With width x length=area,
l (2l -6) = 140
2l^2 - 6l = 140
2l^2 - 6l - 140 = 0
Using the quadratic formula,
we can determine l = 10 or -7
since the length should not be negative,
the length is 10 yard.
Now substitute l=10 into 2l-6.
width = 2(10)-6
= 14 yard
Answer:
4.25
Step-by-step explanation:
Take your cost and divide it by the number of tickets.
55.25/13 = 4.25
21.25/5 = 4.25
No matter which pair you use, the answer is 4.25
