Convert the angle 0=17pi over 18 radians to degree

Shalnov [3]

Answer:

170°

Step-by-step explanation:

To convert from radians to degrees

degree measure = radian measure × $\frac{180}{\pi }$ , thus

degree = $\frac{17\pi }{18}$ × $\frac{180}{\pi }$

Cancel π on numerator/denominator and 18/ 180 by 18

degree measure = = 17 × 10 = 170°

Lesson Posttest

stepladder [879]

Answer:

Step-by-step explanation:

Probability = number of fruit type/total number of fruit. Total number of fruit = 5 + 9 + 5 = 19.

The probability of drawing an apple is P(apple) = number of apples/total number of fruit = 5/19.

The probability of drawing a peach is P(peach) = number of peaches/total number of fruit = 9/19

The probability of drawing an apple is P(orange) = number of oranges/total number of fruit = 5/19

The probability of drawing either an apple, peach or orange at the first draw of fruit from the bag is

P(apple or peach or orange) = P(apple) + P(peach) + P(orange)

= 5/19 + 9/19 + 5/19

= (5 + 9 + 5)/19

= 19/19

= 1

Suppose that a large pumpkin empty a swimming pool in 40 hours and that a small pumpkin empty a pool and 70 hours working togeth

Norma-Jean [14]

Answer:

Total 25.45 hours will be taken to empty the pool.

Step-by-step explanation:

Time taken by large pumpkin to empty the pool=40 hours

Time taken by the smaller pumpkins to empty the pool=70 hours

Amount of pool emptied by large pumpkin in one hour= $\frac{1}{40}$

Amount of pool emptied by small pumpkin in one hour= $\frac{1}{70}$

Amount of pool emptied in one hour if both pumpkins work together=

$\frac{1}{40}$ + $\frac{1}{70}$

= $\frac{11}{280}$

Therefore, the no. of days will be the reciprocal of the amount of work done in one hour ie . $\frac{280}{11}$

Total 25.45 hours will be taken to empty the pool.
