Aaron should use d..............o
x = 4 and x = - 9
In both cases the angles inside the parallel lines are same sided interior angles
24x - 1 + 20x + 5 = 180
44x + 4 = 180 (subtract 4 from both sides )
44x = 176 ( divide both sides by 44 )
x = 
= 4
Similarly
x + 109 + x + 89 = 180
2x + 198 = 180 ( subtract 198 from both sides )
2x = - 18
x = 
= - 9
Answer:
The salt concentration of the mixed solution = 10%
Step-by-step explanation:
First assuming that the concentration of salt given is on a vol% basis.
First solution has 0.7 gallon of 5% salt
Amount of salt in this solution = 5% × 0.7 = 0.035 gallon
Second solution has 0.3 gallon of 22% salt
Amount of salt in this solution = 22% × 0.3 = 0.066 gallon
Total amount of salt in the resulting solution = 0.035 + 0.066 = 0.101 gallon
Total volume of the resulting solution = 0.7 + 0.3 = 1.00 gallon
Concentration of the mixture of salt = (0.101/1) = 0.101 = 10.1% = 10% to the nearest percent
Hope this Helps!!!
Answer:
D. 10
Step-by-step explanation:
The volume of the cylinder is given by the formula ...
V = πr²h
V = π(4 in)²(13 in) = 208π in³
The volume of a cone 3 inches in radius and 7 inches high is ...
V = (1/3)πr²h = (1/3)(3 in)²(7 in) = 21π in³
Then the ratio of the volume of the cylinder to that of the cone is ...
(208π in³)/(21π in³) ≈ 9.905
You would need to fill the funnel about 10 times to fill the can.
