WY = a = 4
ZY = b = 3
As WYZ is forming a right angle triangle, therefore, we can use pythagorean theorem to find the value of c
a2+b2=c2 (4)2+(3)2=C2 16+9=C2 C2=25
Taking square root on both sides
√c2= √25 c=5
The value of c is 5 units.
To find the answer, just divide 48 by 8, which is 6, so the temperature fell by 6°F each minute.
It is 4/18 which can be simplified into 2/9
The total cost is the dependant variable and the number of tickets along with flat out price is the independent variable.
The equation would be y = 1.25x + ?
You would insert 25 for x which equals 31.25 and insert 43.75 for y.
43.75 = 31.25 + ? Then subtract 31.25 from both sides of the equation and you would get....
12.5 = ?
That is your flat rate to get in to the fair
