Answer:

x = 63, y = 27

Step-by-step explanation:

x and 117 are adjacent angles and sum to 180°

x + 117 = 180 ( subtract 117 from 180 )

x = 63

x and y sum to 90°

x + y = 90

63 + y = 90 ( subtract 63 from both sides )

y = 27

The Type B trees produces 120 pears.

<h3>What is meant by percentage?</h3>

A percentage is a number or ratio expressed as a fraction of 100 in mathematics. The percent sign, "%," is commonly used, but the abbreviations "pct.", "pct," and sometimes "pc" are also used. A percentage is a number with no dimensions; it has no unit of measurement.

<h3>How many pears did the Type B trees produce?</h3>
  1. Type A trees produced 20 percent more pears than Type B trees did
  2. Type A trees produced 144 pears.

Let us consider, Type B produced 100% pears.

So, Type A will produce 120%of B, that is 144

144 = 120/100 * B

simplifying the above equation, we get

144 * 100 = 120B

B = 14400/120

B = 120

The value of B = 120.

Hence, the Type B trees produces 120 pears

Therefore, the correct answer is option B) 120.

Suppose i pick a jelly bean at random from a box containing two red and ten blue ones. i record the color and put the jelly bean
gtnhenbr [62]
The probability of picking a blue jelly bean is 10/12=0.833, since there are 10 blue and 12 jelly beans in total.

Each time the probability of picking blue is the same, since put back in the box whatever jelly bean we pick

P(blue, blue, blue) = P(blue) × P(blue) × P(blue) = 0.833×0.833×0.833=0.579


Answer: 0.579
