Answer:
2 + 1 + 5 + 8 + 14 = 30 total marbles
30-14 yellow marbles = 16
16/30 = probability of not yellow
First we need to see the pythagorean formula which is

Substituting the given values of a,b , we will get




And

So we have

So the given triangle is a right triangle .
Answer:
36years
Step-by-step explanation:
Let charity present age be x
Charity daughter present age be y
Charity husband present age be z
If the sum of their ages ten years to come is 117, then;
10+x+10+y+10+z = 117
30+x+y+z = 117
x+y+z = 87 ... 1
If charity is four times as old as her daughter, then;
x = 4y
y = x/4 ... 2
If she is also six years younger than her husband, then;
x = z- 6
z = x+6 .. 3
Substitute 2 and 3 into 1;
x + x/4 + (x+6) = 87
Multiply through by 4
4x + x + 4(x+6) = 4(87)
5x+4x+24 = 348
9x = 348 - 24
9x = 324
x = 324/9
x = 36
hence Charity is 36years old today
Answer:
regular price = 70
Step-by-step explanation:
you are paying 80 percent of the regular price
regular price * 80 percent = new price
regular price * .8 = 56
divide by .8 on each side
regular price *.8 /.8 = 56/.8
regular price = 70
