Answer:
-5
Step-by-step explanation:
We just have to calculate (-1/2) / (1/10) = (-1/2) * 10 = -5.
Answer: 4 3/4
Step-by-step explanation:
3/8 +3/8 + 1/8 +1/2 +1/2 +1/2 +1/2 + 5/8 +5/8 +5/8=
3/8+3/8+1/8+2+5/8+5/8+5/8=
11/4 + 2=
2 · 4 /4 + 11/4=
2 · 4 + 11 / 4=
19/4 =
4 3/4
The proper notation may depend on where you are. In the US, we like there to be one non-zero digit to the left of the decimal point, hence the appropriate form is ...
... 6.59×10¹¹
_____
Elsewhere, the "proper" form may require the first non-zero digit be placed to the right of the decimal point, as in 0.659×10¹². This is also the form used by some computer languages.
In Engineering usage, quite often the desired form is one that has the exponent be a multiple of 3, so the appropriate forms would be 659×10⁹ or 0.659×10¹².
Sometimes when you're doing problems using numbers in scientific notation, it can be convenient to scale the operands so the result comes out with no need for rescaling. For example, if you were to divide 100 by this number, you might write ...
... 100/(65.9×10¹⁰) ≈ 1.517×10⁻¹⁰
Without this "pre-scaling", you would get
... (10²)/(6.59×10¹¹) ≈ 0.1517×10⁻⁹ = 1.517×10⁻¹⁰
which requires rescaling the answer.

Step-by-step explanation:
X^2-9
Answer:
(x+3)(x-3)
Step-by-step explanation:
x²-b² = (x+b)(x-b)
x²-9 = x²-3² = (x+3)(x-3)
Answer:
6 miles
Step-by-step explanation:
Let's say the length of the sides of the square is x.
The area of a square is denoted by: A = x².
Here, we're given that twice the area of the square is 72, so we can write this is 2 times the area, which is 2 * x². Set this equal to 72 and solve:
2x² = 72
x² = 36
x = 6
Thus the answer is 6 miles.
Answer:
6 miles
Step-by-step explanation:
2A = 72
A = 72/2
A = 36
Area = s²
36 = s²
s = 6 miles
