Answer:
295 minutes
Step-by-step explanation:
It is given that Speedy the Sloth drinks tea at a steady rate of 2/7 cups per hour.
Yesterday she drank 1 cup and today she drank 17/42 of a cup more than yesterday. This means today she drank 1 + 17/42 cups.
Time taken to drink 2/7 of a cup = 1 hour = 60 minutes
Time taken to drink 1 cup = 
minutes
Time taken to drink 1+17/42 cups = 
minutes
Since she drinks tea as long as she stay awakes. This means, she stayed awake for 295 minutes today.
Thursday: 2 choices {museum, park}
Friday: 4 choices {shopping, jet ski, hiking, and the choice not chosen for Thu}
Saturday: 1 choice {food}
Sunday: 3 choices {the remaining 3 after Friday's choice}
The total number of ways these choices can be arranged is 2×4×1×3 = 24
The apprpropriate selection is A) 24.
There would be 3 cows which would make it 12 legs, and 2 chickens which would be 4 legs
Answer:
Since we know that ABCD is an isosceles trapezoid, we can also asume that its diagonals have the same length, which means:
AC = BD
=> 7x - 21 = 5x + 13
=> 7x - 5x = 21 + 13
=> 2x = 34
=> x = 34/2 = 17
So the answer is C.
