Answer:
5 pizzas and 17 sodas were bought
Step-by-step explanation:
Here, we want to get the number of pizza and sodas bought
Let n be the number of pizzas bought
we are told that the number of sodas bought was 2 more than 3 times the number of pizzas
So the number of sodas will be;
3n + 2
So let’s have the equations based on the prices;
pizzas cost $9.50, soda cost $1.25
Thus;
9.5n + 1.25(3n + 2) = 68.75
9.5n + 3.75n + 2.5 = 68.75
13.25n = 68.75 - 2.5
13.25n = 66.25
n = 66.25/13.25
n = 5
Number of pizzas bought is 5
number of soda is 3n + 2 = 3(5) + 2 = 15 + 2 = 17
Answer:
37
Step-by-step explanation:
(2 + 3) + 4^2 x (5 − 3)
5 + 4² x 2
5 + 16 x 2
5 + 32
37
Answer:
Rainbow
Step-by-step explanation:
Parabola ⇒ A parabola is a plane curve with a U shape which is mirror-symmetrical. A parabola fits different superficial descriptions and can be proved to define each curves.
A rainbow is a U-shaped seven coloured curve that appears in the sky after or during the rain.

The formula to use is
V = pi*r^2*h
V = volume of cylinder
pi = 3.14 approximately, but we'll leave it as pi
r = radius
h = height
In this problem,
r = 1 since the diameter is 2
h = 4
Plug those two values into the formula
V = pi*r^2*h
V = pi*1^2*4
V = pi*1*4
V = pi*4
V = 4pi
