Answer:
it's 324
Step-by-step explanation:
divide 72 by 4 to get one side, then multiply the side by itself, 18 times 18
It's not clear if this is a right triangle or not. I'm going to assume its any kind of triangle. The third side c is restricted such that...
a - b < c < a + b
4.8 - 0.23 < c < 4.8 + 0.23
4.57 < c < 5.03
If c was allowed to be any real number, then we'd have infinitely many solutions for c. However, we're told that c is a whole number. The only whole number between 4.57 and 5.03 is 5
So c = 5 is the only integer solution
Final Answer: 5
Answer:
Step-by-step explanation:
pyramids have 5 surfaces and a point. a cube has 6 surfaces and is a square
Answer:
12 discs
Step-by-step explanation:
Sheet metal has dimensions of 56 cm by 33 cm. This indicates that it is a rectangle.
A_rectangle = length × width
A_rect = 56 × 33
A_rect = 1848 cm²
It is now melt down and recast into disc's of 7 cm radius and similar thickness.
Thus;
Area of one disc = πr² = π × 7² = 49π
Thus,number of disc's cast = 1848/49π
number of disc's cast = 12
D = b²-4ac = 5² - 4*1*(-24)=25+96 = 121
