By their angles, as in a right triangle all the angles have the same degree.
300 parents
3/4 = x/400, and we are trying to find x.
Multiply the numerator and denominator of 3/4 each by 100 to make the denominator equal 400. This gives 300/400. So, 300/400 = x/400.
Multiply both sides of the equation by 400 to cancel out the division. This gives you 300 = x, so 300 parents said yes to the survey.
The best answer for this question would be:
D. 32
In order to get this, you have to get the sum in the line,
which is the first four people. So the solution would be: 4(23) = 92
For getting the sum of the people in the last 3 would be:
3(34) = 102
Next is the sum of everyone which the solution would be:
6(27) = 162
So the initial solution that we have now would be: F + 92 -
F + 102- F = 162
- F + 194 = 162
- F = 162 - 194
- F = - 32
The (F) here or the fourth person’s age would be= -32 / - 1
or 32
24:56 = 3:7
You can simplify it by dividing with 2
