Using the speed - distance relationship, the time left before the appointed time is 27 minutes.
<u>Recall</u><u> </u><u>:</u>
<u>At</u><u> </u><u>10mph</u><u> </u><u>:</u>
- Distance = 10 × (t + 3) = 10t + 30 - - - (1)
<u>At</u><u> </u><u>12</u><u> </u><u>mph</u><u> </u><u>:</u>
- Distance = 12 × (t - 2) = 12t - 24 - - - - (2)
<em>Equate</em><em> </em><em>(</em><em>1</em><em>)</em><em> </em><em>and</em><em> </em><em>(</em><em>2</em><em>)</em><em> </em><em>:</em>
10t + 30 = 12t - 24
<em>Collect</em><em> </em><em>like</em><em> </em><em>terms</em><em> </em>
10t - 12t = - 24 - 30
-2t = - 54
<em>Divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>-</em><em> </em><em>2</em>
t = 54 / 2
t = 27
Hence, the time left before the appointed time is 27 minutes.

When we have two arcs in a circle, one larger and one smaller, one will be called the minor arc and the other the minor arc.
The name of the arc depends on its size, for example, given the following green and yellow arcs, the green, which is smaller, will be the minor arc:
Therefore, the larger arc is always called Major arc, not minor arc.
The statement is False.
Answer: False
Answer:
The answer is 0.25
Step-by-step explanation:
(1)we group like terms by subtracting 32.50 by 28.75
(2) we subtract 20 and 5 to give us a value of 15
(3)when we subtract 32.50 and 28.75 we get a value of 3.75
(4)so the equation will look like this 3.75t = 15
(5)we divide 3.75 we both the two equations
(6)With a correct calculation, Your answer should be t = 0.25

Answer:
The zoo will cost more money for a group of 12 students to visit.
Step-by-step explanation:
First, you have to divide the costs by the amount of tickets to find out how much you would have to pay for one ticket.
Science Center: $36.76 ÷ 3 = $12.25
Zoo: $51 ÷ 4 = $12.75
Then, the cost for one ticket should be multiplied by 12, the group of students wanting to visit.
Science Center: $12.25 x 12 = $147.04
Zoo: $12.75 x 12 = $153
Comparing the prices, you will see that the zoo will cost $5.96 more dollars than the science center.
