Find the length of base PQ in the trapezoid.

iris [78.8K]

Answer:

PQ = 20

Step-by-step explanation:

Theorem: The length of the median of a trapezoid is the average of the base lengths.

$\frac{PQ + 12}{2} = 16$

PQ + 12 = 32

PQ = 20

See how easy that is if you know the theorem!

Number on the Cube Number of Times Rolled

Natasha2012 [34]

Total number of times cube was rolled = 100.
Total number of times a 6 was rolled = 27.
Probability of rolling a 6 = $\frac{27}{100}$
Total number of times coin was tossed = 100.
Total number of times a head was tossed = 41.
Probability of tossing a head = $\frac{41}{100}$
Therefore, probability of rolling a 6 and tossing a head = $\frac{27}{100}\times\frac{41}{100}=\frac{1107}{10000}$

< Last spring, Kai planted a total of 9 green peppers and tomatoes in the community garden.

ExtremeBDS [4]

Answer:

Step-by-step explanation:

Let x = the number of pepper plants, then (x + 6) = the number of tomato plants. Since the ratio of tomatoes to peppers is 5:2, we have the following:

5/2 = (x + 6)/x

2x + 12 = 5x

12 = 3x

4 = x = the number of pepper plants
