Answer: There is a 30% chance Ricky will pull out a quarter
Step-by-step explanation:
This problem is quite simple, really. Okay, so first we're gonna figure out how many items in total there are. He has 3 quarters, 5 dimes, and 2 nickels. So 3+5+2 is equal to 10. Since there is 3 quarters out of the 10 different options, here is how many quarters are in the bag (aka the probability that Ricky will pull out a quarter): 3/10. 3/10 is the same thing as 30%, so there is a 30 percent chance Ricky will pull out a quarter.
Answer:
the answer will be -1/2

Answer:
<em>The required values are a = 29°, b = 20°</em>
Step-by-step explanation:
<u>Angles and Lines</u>
The image shows two lines crossing at a point where three angles are marked: 57°, 7b-17, and 2a-1.
It can be noted that 57° and 7b-17 are linear angles whose sum is 180°:
57° + 7b - 17° = 180°
Solving for b:
7b = 180° + 17° - 57°
7b = 140°
b = 140°/7 = 20°
b = 20°
It can also be noted that 57° and 2a-1 are vertical angles (opposite angles). Vertical angles are congruent, thus:
57° = 2a - 1°
Adding 1:
2a = 58°
a = 29°
The required values are a = 29°, b = 20°
