Mike observed that 75% of the students of a school liked skating. If 35 students of the school did not like skating, the number of students who liked skating was ______. (only put numeric values, no other symbols)
Answers
25%=35 students how about 75%
75 x 35 divided by 25=105 students
105
25%=35 students but you have 75%
so 75*30divided by 25=90 students

The volume of a sphere is given by the formula V = 4/3 πr³ , where V is the volume of the sphere and r is its radius. We know that the radius is 9 inches.
Calculations
Formula = V=4/3πr³
V=4/3πr³
v=4/3πr³ ( 9 ) = r
r³ = 9 x 9 x 9 = 729
V=972π

2x - 5y = - 15
2x = 5y - 15
2x = 5(y - 3)
x = [5(y - 3)]/2
Similarly the way the value of y can be determined in terms of "x" can also be shown.
2x - 5y = - 15
-5y = - 2x - 15
-5y = -(2x + 15)
5y = 2x + 15
y = (2x +15)/5
= (2x/5) + (15/5)
= (2x/5) + 3
So the final value of x is [5(y -3)]/2 and the value of y is (2x/5) + 3.

The number of steps it takes you to get to the remainder and quotient depends on how good your estimates are. For instance in the above diagram. You can see two different approaches of dividing 986 by 26 using partial quotients.
In the second approach in which there are fewer steps, We estimated that there are about 35 [26s] in 986. The 35 is our first partial quotient. We then multiply
Next we subtract
We again estimated that there are at least 2 [26s] in 76. The 2 is our second partial quotient.
We then multiply again,
Next, we subtract,
Now there are no 26s in 24. Hence 24 is the remainder.

Answer:
Western U gets 20 million
Norther U gets 40 million
Eastern U gets 50 million
Step-by-step explanation:
We need to find the amount each university gets.
Let
Northern U get n
Western U get w
Eastern U get e
We can write equations from the given word problem:
n + w + e = 110
and
n = 2w
e = n + w - 10
Putting 2nd in 3rd, we get:
e = 2w + w - 10
e = 3w - 10
Now putting this and 2nd in first, we solve for w:
n + w + e = 110
2w + w + 3w - 10 = 110
6w = 120
w = 20
AND n = 2 (20) = 40
AND e = 3(20) - 10 = 50
So,
Western U gets 20 million
Norther U gets 40 million
Eastern U gets 50 million
