Answer:
A. 18.4
Step-by-step explanation:
The mean is the average. In order to find the answer you must add all the values of the variables and divide them by the number of variables. Simply just add 14, 15, 18, 20, and 25, and then divide it by 5 (the number of variables). Then you get your answer.
14+15+18+20+25=92
92/5=18.4
A. 18.4
The perimeter is about 82 yards
first, the perimeter of the rectangles is 30*2 = 60 (the 7 is not a part of the overall perimeter so we do not need to add it)
the "perimeter" (circumference) of the 2 semi circles = (22/7)*7 = 22by using the formula C = pi*d (2 semi circles of the same diamter = 1 circle)
now just add the 2 answers
22 + 60
= 82 yards
3/4x + 5 - 1/2x = 3
3/4x - 1/2x = 3 - 5
3/4x - 2/4x = -2
1/4x = -2
x = -2 / (1/4)
x = -2 * 4/1
x = -8 <==
21.2 (21.2) is (=) 54500 (54500) of (times) what number (?)
21.2=54500 times ?
divide oth sides by 54500
21.2/54500=?
