For the right angle triangles to find the hypotenuse square both the sides that are given and add them together, then you need to square root your answer
If you are finding a different side like triangle 2 use a^2 = c^2 - b^2 where a is the side you are finding, c being the hypotenuse and b being the other side.

Josiah kept track of how many songs of each genre were played in an hour from his MP3 player. The counts are displayed in the ta
german

Based on the number of songs in each genre that Josiah listened to, the statements about his solution that are true are:

  • He should have found the average of the number of rock songs by averaging 4 and 6 to get 5.
  • He did not multiply the numerator and denominator by the correct number to equal 1,500.
  • He should have multiplied the numerator and denominator by 75, not 30, because 20 times 75 = 1,500.

<h3>What did Josiah do wrong?</h3>

To find the average of the number of rock songs, he should have taken the average of rock songs he listened to which were 4 and 6:

= (4 + 6) / 2

= 5

Because he has a total of 1,500 songs on his player, he should have multiplied both the numerator and denominator by a number that would lead to 1,500 which is 75 and not 30.

- 50 × - 5 = 250

250 × - 5 = - 1250

the sequence is - 2, 10, - 50, 250, - 1250

kirill115 [55]

Answer:

w=2r

r= w/2

r- w/2 = 0

w -2r= 0

Step-by-step explanation:

Let w be the number of weeks and r be the number of recipes learnt . So he will learn 2 recipes each week .Equating gives

w=2r

when w= 1

w= 2(1) = 2

For 1st week 2 recipes are learned

when w= 2

w= 2( 2) = 4

For 2nd week 4 recipes are learned.

or

when r= 2

r= w/2

r =2/2  = 1  one  recipe is learned in half of the week  

r- w/2 = 0

or

w -2r= 0
