Answer:
Step-by-step explanation:
The correct answer is not the first answer, but the second answer in the middle. The third answer is the correct one because, since it has the correct exponent, that is, 0.51 grams.

The approximate total mass is the number of atoms multiplied by the weight of an atom.
The approximate overall mass=3.06 10²³ atoms. (1.67 10⁻²⁴ grams/1 atom) which is equivalent to a mass of 0.51 grams. (1.67 10⁻²⁴ grams/1 atom) = 0.51102 g ≈ 0.51 g
Answer: B. 0.51 grams, because (3.06 ⋅ 1.67) ⋅(1023 ⋅ 10–24) = 5.1102 ⋅ 10–1
The second one (straight line parallel to the y axis)
Answer:
Total taxes = $1,520
Step-by-step explanation:
We have two separate calculations for the taxes:
The tax rate for the first $5,000 of Clarisa's gross pay is 1%, so the amount of tax paid in this case is
1% * 5000 = $50
The tax rate for the amount of value over $5,000 (that is, 54,000 - 5,000 = 49,000) is 3%, so the amount of tax is:
3% * 49,000 = $1,470
So, the total amount deducted for state taxes is:
Total taxes = 50 + 1470 = $1,520
Answer:
x is equal to 0.94 and -1.94
Step-by-step explanation:
3x² + 3x + 7 = 0
9x² + 9x + 21 = 0
9x² + 9x + 2.25 = 18.75
(3x + 1.5)² = 18.75
3x + 1.5 = ±√18.75
3x = -1.5 ±√18.75
x = (-1.5 ±√18.75) / 3
x = 0.94, -1.94
Answer:
The drone takes 2.25 seconds to be higher than the basketball.
Step-by-step explanation:
Based on the definitions given on statement and the image attached below, the red line represents the height of the basketball and the blue line represents the height of the drone, respectively. The height of the drone is higher than the height of the basketball when the y-value of the former is higher than the y-value of the latter. The time is contained in the +x semiaxis.
According to the figure, the drone takes 2.25 seconds to be higher than the basketball.
