Well, in percentages, Other = 100% - 40% - 37,5% = 22,5%
In numbers, Other = 18.
If 18___22.5%=0.225
Then x___100%=1
So x = (18*1)/0.225 = 18/0.225 = 80, and 80 is the first answer, the number of students participated.
For second question, which is how many chose football, we have:
x_____37.5%=0.375
18____22.5%=0.225
x = (18* 0.375) / 0.225 = 30
The second answer is 30.
Answer: See explanation
Step-by-step explanation:
We should note that the hypothenuse is the longest side in a triangle. Therefore, the length of the other side will be represented by x. This is then solved below:
x² + 3² = 5²
x² + 9 = 25
x² = 25 - 9
x² = 16
x = ✓16
x = 4cm
The other leg is 4cm
Joni shouldn't have added the hypothenuse to the other leg but rather subtracted the square of the other leg from the square of the hypothenuse and then find the square root.
You are adding by 5 in the sequence.
If f(1) is -7
f(2) = -2
f(3)= 3
f(4)=8
f(5)=13
f(6)=18
Therefore, f(7)=23
Multiply the -3 by what is inside the parentheses.
-3y + 15 =24
subtract 15 from both sides.
-3y=9
divide by -3 on both sides.
y = -3
425 would be the answer you are looking for.
