Answer:
5.50x + 2y ≤ 18
Step-by-step explanation:
Romona has a total of $18 and she has to spend it on dog food.
Dry god food cost $5.50 per bag and wet dog food cost $2.00 per can.
We have to write an inequality to show the above condition.
Let the number of dry and wet dog food she buys be x and y.
The total cost of dog food must be less than $18.
Then,
5.50x + 2y ≤ 18
This is the required linear inequality.
Answer:
D. 0.857
Step-by-step explanation:
The coefficient of determination, R-squared, is simply the square of the correlation coefficient;
R-squared = r^2
R-squared = 0.926^2
R-squared = 0.857
Therefore, the coefficient of determination is 0.857.
Answer:
3,943.84
Step-by-step explanation:
Since we know the angle of the arc is 70°, its length will be 7/36 of the whole circumference. The circumference, which is 2*pi*r, is 20 pi = 62.8, so the arc JL is 7/36 * 62.8 = 3,943.84
Angle DOC is a vertical angle to AOB. Since this is a central angle, arc AB is 50.
Angles AOE, EOD, and DOC are supplementary. 180 - 60 - 50 = 70. Angle AOE is also central, so arc AE is 70.
All arcs combined add to 360, so 360 - 70 - 50 = 240 (we subtracted every other arc besides ECB, which is 240.)
We know angle BOC is vertical to the sum of AOE and EOD, so 60+ 70 = 130. Angle BOC is 130.
Answer:
213.41 mph.
Step-by-step explanation:
Multiply by 3600 ( seconds in an hour) and divide by 5280 (feet in a mile).
= 213.41 mph.
