Step-by-step explanation:
Model:
s = slices
x = pizzas ordered
s = .8(.45x) + .12(.55x)
Now plugin 20 for x and you will get the total number of slices.
s = .8(.45x) + .12(.55x)
s = .8(.45(20)) + .12(.55(20))
s = 204 slices
Note, we could make this model different and smaller but I chose this method because it demonstrates what is going on with the word problem
The area of the city park will be equal to 3952 square units.
<h3>What is the area?</h3>
The Area is defined as the space occupied by the two-dimensional geometry in a plane.
We have the following information:-
In City Park, the playground takes up 3/8 of the area:-
The soccer field area is 1/3 of the playground area.
The product 13×38 can be used to find the area of the soccer field
SF= 13 x 38=494 square units
Noe the PGA will be:-
PGA =3 x SF
PGA= 3 x494=1482 square unit
Now the area of the city park will be calculated as:-
CP=3952 square unit
Hence the area of the city park will be equal to 3952 square units.

Step-by-step explanation:
Base = 16.9
height = 10.4
Area = ½b×h
A = ½(16.9×10.4)
A = ½(175.76)
Area = 175.76/2
A = 87.88ft²
Answer:
1,3,6,10,15,21,…..
These are all the sum of natural numbers upto the n
So, in this series
1st Term = 1
2nd Term = 1+2 = 3
3rd Term = 1+2+3 = 6
4th Term = 1+2+3+4 = 10
So,
Term - n = 1+2+3+….+n = n(n+1)/2
That’s your answer n(n+1)/2
Good Luck
