Answer:
I don't know but I can help you understand it.
Step-by-step explanation:
First find the the answer to the problem and then try to compare all of them to each other and choose the one that makes the most sense.
Answer:
Volume = 1114.1 
Step-by-step explanation:
Recall that the formula for the volume of a pyramid is given by:
where B is the area of the pyramid's base (in our case a square of side 12,8 in), and H the pyramid's height (in our case 20.4 in).
Then the square base of the pyramid has an area given by: 
Finally,we can now write the volume of the pyramid as:
Rounding the answer to a tenth of a cubic inch, we get:
Volume = 1114.1
Answer:
The smaller number is 11
Step-by-step explanation:
The question is
One number is 3 less than a second number. Twice the second number is 16 less than 4 times the first. Find the smaller of two numbers
Let
x and y the numbers
x=y-3 ----> equation A
2y=4x-16 ----> equation B
Substitute equation A in equation B and solve for y
2y=4(y-3)-16
2y=4y-12-16
4y-2y=12+16
2y=28
y=14
x=14-3=11
A square with 1,536 soldiers are not possible, i.e. the square root of 1,536 is about 39.191, which means that 1,536 is not a square a number. In order for it to be a square number, we have to round up 39.191 (because it says "how many more soldiers") to 40 and 40×40=1,600 and 1,600-1,536, so we need 64 more soldiers.
The greatest 4 digit number is simple. If the square root of 10,000 is 100, than, one can assume that because 100-1=99, the resulting answer of 99×99 is less than 10,000, meaning that is is 4 digits. 99×99=9,801.
90 + 50 = 140
180 - 140 = 40
40 degrees is the answer
This triangle is a right angle triangle.
