When you don’t know the degree of a shape just use this form
180(n-2). Where n is the number sides of the shape.
There are 4 sides
180(4-2) = 180(2) = 360
So this shape is 360 degrees
120 + 120 + 60 +x = 360
300 + x = 360
X= 60
But as you can see that you don’t need this form for this question the alternate interior show you that the missing angles is 60
Answer:
A) 21.25 + 0.1m <= 60
B) 387
Step-by-step explanation:
I think the problem means to say that the first 1000 text messages are included in the $21.25 plan, and messages above the included 1000 cost $0.10 each.
A)
Let m = number of text messages above 1000.
0.1m is the cost of the messages past the included 1000.
The cost of the plan ($21.25) plus the cost of the messages above 1000, must cost up to $60.
21.25 + 0.1m <= 60
B)
21.25 + 0.1m <= 60
0.1m <= 38.75
m <= 38.75/0.1
m <= 387.5
Answer: 387
Total:20
That means all fractions will be out of 20
Red: 6 → 6/20
Purple: 8 → 8/20
Add:
8/20 + 6/20 = 14/20
14/20 = 7/10
The probability is 7/10
Hope this helps :)
To figure it out you have to multiply all of the sides together.
so 24 x 8 x 14 x 8.7 x 8 x 26.
