The easiest way to work out average times is to convert them all to seconds. 60 secs makes 1 min etc. Add all the seconds. Then divide the sum by the number of entries, hope this works.
Step-by-step explanation:
16.30 and 16.3 equal. If you ever have a problem like that then you just add on a zero.
Example:
19.4500 = 19.45 Just add two zeros on the end
19.45 + two zeros = 1.4500
Answer:
68 cm²
Step-by-step explanation:
I don't see what you mean for each figure but here goes nothing!
We can split the figure in 2 rectangles
We find the first rectangle by doing 4 x 12 = 48 cm²
The second rectangle would be 5 x 4 = 20 cm²
Therfore we add them up into 20 + 48 = 68 cm²
Hope This Helps!
Answer:
B. 664 square inches
Step-by-step explanation:
14 * 10 =140
140 * 2 = 280
8 * 10 = 80
80 * 2 = 160
14 * 8 =112
112 * 2 = 224
280 + 160 + 224 = 664
Therefore, your answer would be B. 664 square inches.
F(x)=
