You need to divide the number of pages by the number of minutes. 7 1/2, or 7.5, divided by 9 is .83333333. To simplify this you could put .8 of a page, or 8/10.
Answer:
1st angle is 28° and the 2nd angle is 62°
Step-by-step explanation:
Complementary angles mean that the angles add up to 90 so:
2x - 2 + 5x - 13 = 90
7x - 15 = 90
7x = 90 + 15
7x = 105
x = 15
Plugging in:
2x - 2
2(15) - 2
30 - 2
28
5x - 13
5(15) - 13
75 - 13
62

Step-by-step explanation:
Mrs. Lincoln has 15 girls and 10 boys in her homeroom. She randomly selects two students. The total number of students is 25.
The probability of choosing one girl is:
15 / 25 = 3 / 5
Now, 24 students are left.
The probability of choosing one boy is:
10 / 24 = 5 / 12
Therefore, the probability of choosing one girl and one boy is:
3 / 5 * 5 / 12
= 3 / 12
= 1/4
