Answer: 666.1
Step-by-step explanation:
(2.58 x 105) + (3.8 x 104)
270.9 + 395.2
666.1
Use the Pythagorean Theorem. a^2+ b^2=c^2.
In this case, it is c^2-b^2=a^2, so your answer is 4.686 mm^2. Round if you need to.
Answer:
v > -25/p
r = -5 +7/3 w
Step-by-step explanation:
- pv + 40 < 65
Subtract 40 from each side
- pv + 40-40 < 65-40
-pv < 25
Divide each side by -p (remember to flip the inequality since we are dividing by a negative)
-pv/-p > 25/-p
v > -25/p
7w - 3r = 15
Subtract 7w from each side
7w-7w - 3r = 15-7w
-3r = 15-7w
Divide by -3
-3r/-3 = (15-7w)/-3
r = -5 +7/3 w
Factors are numbers that can be multiplied by an integer to obtain the desired integer
The size of the human hair is <u>1.0 × 10⁻⁴ meters </u>
Reason:
The given parameters are;
The size of an hydrogen atom is 5 × 10⁻¹¹ meters
The width of the human hair is 6 times as big
Therefore, we have;
The width of the human hair is 2 × 10⁶ times as big, therefore, we have;
The size of the human hair = 5× 10⁻¹¹ × 2 × 10⁶ = 1.0 × 10⁻⁴
The size of the human hair is <u>1.0 × 10⁻⁴ meters</u>
