Answer:
line QR
Step-by-step explanation:
Plane QRB is the front face. Plane TSR is the top face. The planes intersect at the top front edge, line QR.
Let us represent number of one person tubes rented by x and, number of cooler tubes rented by y As per the situation, total tubes are 15, hence x + y = 15 equation 1 Also, total expenditure on tubes is $270, therefore 20x + 12.5y = 270 equation 2 Linear equation written above, equation 1 and equation 2 represent given situation. Now, let us solve these equations to find number of tubes rented Multiplying equation 1 by 20 and subtracting equation 2 from it, we get 20x + 20y - 20x -12.5y = 300 - 270 7.5y = 30 y = 4 and from equation 1, x + 4 = 15 gives, x = 11 Therefore, number of person tubes = 11, number of cooler tubes = 4
If you have three quarters and each is a value of 25¢ you add and get 75¢ and you add the $4 which gives you $4.75
The equation of the parabola that similar to f(x) = 
but the vertex is (3, 5) in the standard form is y = 
+ 5
The equation of the parabola
f(x) =
The standard vertex form of a parabola is
y = 
+ k
The coordinates of the vertex of a parabola = (3, 5)
Where (h, k) is the coordinates
From the given function of the parabola f(x) =
The value of a = 7
Substitute the values in the vertex form of a parabola
y = + 5
Hence, the equation of the parabola that is similar to f(x) = but the vertex is (3, 5) in the standard form is y = + 5

Answer:
6 degrees
Step-by-step explanation:
x + 12x + 17x = 180
x = 6
The angles are 6 : 72 : 102 so the smallest is 6 degrees.
