Answer:
Step-by-step explanation:
Overall students=50
35 -> j.
25 -> r.
16-> j.+r.
35-16=19 students joined j.
25-16=9 joined r.
50-19+9
50-28=22
The answer is 22
It would be nice if you could give me the brainliest rating. Best of luck!
Answer:
0.03
Step-by-step explanation:
Yes, we all appreciate the copy and paste from Khan Academy
A)
4(q - 10) = 76..... Tim earned 4 points for each correct answer, totaling 76 points. He got 10 answers right less than the total number of questions on the test.
b)
q = 10 + 76/4
q = 29
Thus, the overall number of questions on Tim's math test amounted to 29.
Answer:
The rotation angle measures 2.11 °
Step-by-step explanation:
Stated as follows:
The radius of the circular path = r = 18 feet
The distance rolled by the wheel = l = 38 feet
Let us denote the angle of rotation as Ф
Now, according to the problem:
∵ the length of an arc at the center corresponds to an angle Ф
Thus,
distance rolled by the wheel = π × radius × 
As 180° represents π radians
And π approximates to 3.14
Thus, distance rolled by the wheel = 180 °× radius × 
That is l = r × Ф
So, Ф = 
Consequently, Ф = 
Therefore, Ф = 2.11 °
Thus, the rotation angle is Ф = 2.11 °
Hence, the rotation angle is 2.11 ° Answer
To find the answer, subtract the total percentage of 24.65% and $48 from 1986, resulting in the final value.
