Answer:
0.0405
Step-by-step explanation:
10^-2 is the same as 1/100, so if you multiply 4.05 x 1/100, you get 0.0405.
Another way to think about it is by looking at the exponent -2. You need to move the decimal point 2 spaces to the left -- and add zeroes to any spaces that don't already have numbers.
So if you start with 4.05, and move the decimal one space to the left, you get 0.405, and then you move it one more space, and you get 0.0405.
No because 48 is not a multiple of 5
Answer:
The length of a side can be 3·√42 ft long
Step-by-step explanation:
The question is a word problem regarding the formula for the area of a square
The parameters given are;
Available concrete = Enough to pave 378 ft.²
Shape of patio Vince wants to make = Square
Therefore, the dimensions of the sides, s, of a square patio that has an area of 378 ft.² is found as follows;
s² = 378
Therefore, s = √378 = √(9 × 42) = 3·√42 ft
Hence, the length of a side can be 3·√42 ft long.
Answer:
-1000
Step-by-step explanation:
-10 times -10 makes 100 as negative cancel each other
100 times -10 make -1000
