Answer:

see explanation

Step-by-step explanation:

Since there are 3 parallel lines, then

a and 31° are corresponding angles and congruent, thus

a = 31°

b and 31° are same- side interior angles and supplementary, thus

b = 180° - 31° = 149°

c and b are vertical angles and congruent, thus

c = 149°

d and 31° are alternate angles and congruent, thus

d = 31°

a = 31°, b = 149°, c = 149°, d = 31°

Out of 275 coins, 120 are quarters. Of the remaining coins, 20% are nickels and the rest are dimes and pennies. There are 3 penn

Airida [17]

Total number of coins in question = 275
Number of quarters among the total coins = 120
Then
Remaining number of coins = 275 - 120
      = 155
Percentage of coins that are nickel = 20%
Then
Number of coins that are nickel = (20/100) * 155
   = 155/5
   = 31
Remaining number of coins = 155 - 31
      = 124
Ratio of dimes to pennies = 1:3
Let us assume the common ratio to be = x
Then
x + 3x = 124
4x = 124
x = 124/4
   = 31
So
The number of pennies = 3 * 31
   = 93
From the above deduction we can conclude that there are 93 pennies. The correct option among all the options given in the question is option "C".
