Answer:
Step-by-step explanation:
Formula
Area = 1/2 (b1 + b2)*h
Givens
b1 = 11 m
b2 = 13 m
Area = 96
h = ?
Solution
96 = 1/2 (11 + 13) * h Multiply by 2 Combine the bases as well.
96*2 = (24) * h Divide by 24
96*2/24 = h Multiply by 2 and divide by 24
h = 8

Step-by-step explanation:
Don't take my word for it
480 pennies.
25% are dated before 1980, therefore:
1200(total):100 = 12 (1%)
12(1%)x25 = 300 (25%)
35% are dated from 1980 to 2000, therefore:
12(1%)x35 = 420 (35%)
25% are dated before 1980, 35% are dated from 1980 to 2000 and the rest are dated after 2000.
25% + 35% = 60%.
300(25%) + 420(35%) = 720.
60% = 720.
100%-60% = 40%.
40% is the amount of pennies that are dated after 2000.
The total (100%) of the pennies is 1200.
We also know that 60% of the total (1200) is 720.
1200(100%) - 720(60%) = 480(40%).
Therefore, the amount of pennies dated after 2000 in Russell’s Collection is 480.
