Answer:
It's 3 x 7 pond or a 7 x 3 pond
Step-by-step explanation:
Let the rectangular pond have dimensions l x b.
ATQ, l*b=21 and 2(l+b)=20. Solving it, we get l=3 or 7 and b=7 or 3.
Answer:
b. mode = 88, median = 77
Step-by-step explanation:
First, arrange all the numbers least to greatest.
53, 71, 75, 79, 88, 88
The mode is the number that occurs the most.
mode = 88
The median is the middle number. Since there is an even number of numbers, look at the two middle numbers 75 and 79. Add them together and divide by two (finding the average or mean of the numbers).
75 + 79 = 154
154/2 = 77
median = 77
Answer: Well if you divide 4200 by 42, you will get 100, which is a multiple of 10
