For this case we have that by definition, the equation of the line of the point-slope form is given by:
Where:
m: It's the slope
It is a point through which the line passes
According to the given statement we have:
Substituting we have:
Finally, the equation is:
Answer:
Answer: 34.2 pounds
Step-by-step explanation:
First, convert 15 4/5 into an improper fraction. You should get 79/5. Then, convert 50 into a fraction that has a denominator of 5. Right now, 50= 50/1 so just multiply the top and bottom by 5 to make it 250/5. Then, subtract 79/5 from 250/5. You should get 171/5. Lastly, simplify. You should get 34.2 pounds as your final answer. Hope this helps!

Answer:
2.0
Step-by-step explanation:
the goa for a student with 80% average is 2.0
1 quart is approximately 9.464 x 10⁻⁴ cubic meter, so the amount of oil that was spilled is about
0.50 qt = (0.50 qt) * (0.0009464 m³/qt) = 4.732 x 10⁻⁴ m³
The pool has a cross sectional area of (25.0 m) * (30.0 m) = 750 m² = 7.5 x 10² m².
Assuming the oil spreads completely across the surface of the pool, you can get its thickness by dividing the volume of oil by this cross sectional area.
(4.732 x 10⁻⁴ m³) / (7.5 x 10² m²) = 4.732/7.5 x 10⁻⁶ m ≈ 6.309 x 10⁻⁷ m
1 m is exactly 100 cm, so multiply this result by 100 = 10² to get a thickness of
6.309 x 10⁻⁷ m = (6.309 x 10⁻⁷ m) * (10² cm/m) = 6.309 x 10⁻⁵ cm
or 0.00006309 cm.
