Answer:
20
Step-by-step explanation:
Area=base times height
Base=4 cm, height=5
4 x 5 =20
Answer: 20cm^2
Collection 1, no of marbles = 125
Collection 2, no of marbles =36 fewer = 125-36 =89
Collection 3, no of marbles = 53 more =125+53 =178
Hence total marbles = 125+89+178
= 392
Given that he uses 14 trays to hold all the marables
Let us assume that he distributes equally all 392 marbles in 14 trays
Then marbles in each tray = 392/14 = 27
Thus division is used for finding out the no of marbles in a tray.
For finding out no of marbles in 3 trays, we get = 3x27 = 81 marbles
(Here direct variation is used)
Answer is 81 marbles

Answer:
x.
Step-by-step explanation:
If h(x) is the inverse of f(x) them h(f(x)) = x.
The hot dogs remaining are decreasing by 11 as 2 minutes go by.
11 / 2 = 5.5
So he's eating 5.5 hot dogs per minute.
Minutes 2 4 6 8 9
Hot dogs remaining 49 38 27 16 5
