Answer:
60
Step-by-step explanation:
There are 2+5 = 7 ratio units of students. If we multiply the numbers by 5, we can have a total of 35 ratio units of students: 10 : 25.
Now, we can substitute this into the ratio of teachers to students:
teachers : students = 3 : 35
teachers : (male students : female students) = 3 : (10 : 25)
Then the number of teachers is seen to be 3/25 of the number of female students:
(3/25)(500) = 60 . . . teachers
Answer:
4. Between 11:30 and 12:00, they did nothing. The graph didn't go up or down, it just stayed the same meaning they did nothing.
5. 5 miles an hour
Step-by-step explanation:
You first have to make the denominators the same 1/7x3/3 and 1/3 X 7/7
3/21 + 7/21 = 10/21
the answer is 10/21
The tower is 75 feet, the wire is 20 feet below the top so the wire is 55 feet above the ground.
The length of the wire is the hypotenuse of a right triangle.
Using the law of cosine:
Cos(angle) = Adjacent leg / Hypotenuse.
Cos(46) = 55 / x
X = 55/cos(46)
x = 79.2 feet
