It is a square based pyramid where,
Length (l)=9
Height (h)=10
Slant height (s)=11
For, volume (V) = 1/3 l^2*h
=1/3 9^2*10
=1/3 *810
=270
For, surface area = 2sl
= 2*11*9
=198
Answer:
%88.88... and on and on
Formula Nonsense: percentage = b/l then *100 add % sign
so P= 32/36 so 0.888....*100= 88.88... so she made 88%
There is a 50%, or 1/2, chance of getting heads on each flip. Each of the 500 trials is independent. Because there is a 1/2 chance of getting heads, you would expect half of them to land on heads. 500/2 = 250. You would theoretically expect 250 heads if you tossed an unbiased coin 500 times.
What's the first and third quartile of -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 7, 7, 7

There are 14 total numbers.
Make a list of the 7 lowest numbers:
-5, -4, -3, -2, -1, 0 , 1
The first quartile is the middle value of the lower half of numbers
Since there are 7 numbers ( odd number), the middle value is the middle number, which is -2
Now make a list of the 7 highest numbers:
2, 3 , 4, 5 , 7, 7, 7
The 3rd quartile is the middle value of the higher half of numbers.
Again because there are 7 numbers ( odd number), the middle value is the middle number, which would be 5.
First quartile = -2
Third quartile = 5

borrows $16000 to buy a car he pays simple interest at an annual rate of 6%
over a period of 3.5 years how much does he pay all together?
Let’s calculate
=> 16 000 dollars is the amount he borrowed
=> 6% is the annual interest
=> 3.5 years us the total years that he will be paying it.
Solutions:
=> 16 000 dollars * .06 = 960 dollars is the annual interests
=> 960 * 3.5 = 3 360 dollars for 3.5 years
=> 16 000 + 3 360 = 19 360 dollars
