It depends on the type of pen you are using. Just find the height, length and width of the pen and multiply you findings and that should give you the volume.
Answer:
Cameron found 23 quarters and 57 dimes.
Step-by-step explanation:
Let the number of quarters Cameron found = Q
And the number of dimes = D
Since, total number of coins were 80,
Q + D = 80 -----(1)
Total amount of the coins was $11.45,
0.1D + 0.25Q = 11.45
10D + 25Q = 1145
2D + 5Q = 229 -----(2)
Equation (1) multiplied by 2 then subtracted by equation (2),
(2D + 5Q) - 2(Q + D) = 229 - 2(80)
(2D - 2D) + (5Q - 2Q) = 229 - 160
3Q = 69
Q = 23
From equation (1),
23 + D = 80
D = 57
Cameron found 23 quarters and 57 dimes.
Answer:
Step-by-step explanation:
AP*BP=CP*PD
2BP=xy=28
BP=28/2=14
AB=AP+BP=2+14=16
There are 24 students in the class.
3/4 = 0.75
18/3 = 6
18+6 = 24
