Answer:
2826 inches^2
Step-by-step explanation:
The general formula for the total surface area of a regular pyramid is
T.S.A.=12pl+B
Where p represents the perimeter of the base, l the slant height and B the area of the base.
The perimeter of the base is.
p=2L+2W
P=2*10+2*9
P=20+18
P= 38 inches
The area of the base is.
B=10*9
B=90in^2
T.S.A.=12(38)(6)+90
T.S.A=2736+90
T.S.A=2826 inches^2
Hence the paper needed is 2826 inches^2
the answer is 20/72 = x/480 . this is because u have to add the numbers for the first sample to find the sample size and then make a ratio to determine if the sample size increases to 480 .
Answer: {MMM ,MCC ,CMC, CCM ,CMM ,MCM ,MMC ,CCC }
Let C denotes the event when dog catches the throw and M denotes the event when dog misses the throw.
Given: Caleb throws a ball three times for his dog leo.
Then the sample space for the situation is given by :-
{MMM ,MCC ,CMC, CCM ,CMM ,MCM ,MMC ,CCC }
p = 2(l+w)
divide by 2
p/2 = l+w
subtract l from both sides
p/2 - l = 2
Choice c
29.6 feet
