12 pizzas because
3 pizzas for ever 2 sides
3/2
x/8
X=12.
Area of rectangle = LxW = 13x7 = 91
Area of triangle = bxh/2 = 7x7/2= 24.5
Total area= 91+24.5= 115.5 in^2
The total surface area of a cylinder is given by the formula
Given diameter, d=12meters, we will solve for radius
The height is given as 9meters
Substituting for r and h in the formula will give
Hence the surface area of the cylinder is 565.2m²
5x + y = 9....multiply by 7
10x - 7y = -18
----------------
35x + 7y = 63 (result of multiplying by 7)
10x - 7y = -18
----------------add
45x = 45
x = 45/45
x = 1
5x + y = 9
5(1) + y = 9
5 + y = 9
y = 9 - 5
y = 4
solution is : (1,4)
=========================
-4x + 9y = 9
x - 3y = -6 ....multiply by 4
----------------
-4x + 9y = 9
4x - 12y = -24 (result of multiplying by 4)
---------------add
- 3y = - 15
y = -15/-3
y = 5
x - 3y = -6
x - 3(5) = -6
x - 15 = -6
x = -6 + 15
x = 9
solution is : (9,5)
Answer:
153
Step-by-step explanation:
If the table adds up to 20 and opened toe counts for 45% of the total. then 45% of 340 is 153 !
