So you are going to multiply the fractions by 10,000 to find the amount of money used on that item.
1/2 x 10,000 = 5,000 - FOOD
1/4 x 10,000 = 2,500 - BEVERAGES
1/10 x 10,000 = 1,000 - DECORATIONS
5,000 + 2,500 + 1,000 = 8,500
10,000 - 8,500 = MONEY SPENT ON STAFFING
= 1,500
15.6 - 11.7 = 3.9
3.9 ÷ 15.6 = .25
25% of change
Answer: 0.058
Step-by-step explanation:
Number of quarters = 15
Number of dimes = 9
Number of nickels = 10
Number of pennies = 6
Total number of coins = 40
The probability of selecting a quarter first will be 15/40 = 3/8
Since it's not replaced, there'll be 39 coins left and the probability of choosing a penny is 6/39 = 2/13
Therefore, P(quarter, then penny) will be:
= 3/8 × 2/13
= 6/104
= 0.058
Answer:
equate
Step-by-step explanation:
4(2x + 5) = 3(2x + 8)
8x + 20 = 6x + 24
2x = 4
x = 2
substitute back in to find side measures and perimeters
