Answer: A popcorn costs $9
Step-by-step explanation:
Let popcorn be represented by p
Let drinks be represented by d.
Samuel spends a total of $36.75 on 1 bag of popcorn and 3 drinks. This will be: p + 3d = 36.75
Sebastian spends a totally of $138.00 on 3 bags of popcorn and 12 drinks. This will be: 3p + 12d= 138
p + 3d = 36.75 ........... i
3p + 12d = 138 ............ ii
Multiply equation i by 3
Multiply equation ii by 1
3p + 9d = 110.25 ....... iii
3p + 12d = 138 ............ iv
Subtract equation iv from iii
-3d = -27.75
3d = 27.75
Divide both side by 3
d = 9.25
A drink cost $9.25
From equation i
p + 3d = 36.75
P + 3(9.25) = 36.75
P + 27.75 = 36.75
P= 36.75 - 27.75
P= $9
A popcorn cost $9
Answer:
(i) The equivalent coordinates in rectangular form are
.
(ii) The equivalent coordinates in rectangular form are
.
Step-by-step explanation:
In this exercise we must find the equivalent coordinates in rectangular form from polar form. That is:

Where:
- Norm of vector, dimensionless.
- Direction of vector with respect to +x semiaxis, measured in sexagesimal degrees.
(i) (
,
)


The equivalent coordinates in rectangular form are
.
(ii) (
,
)


The equivalent coordinates in rectangular form are
.
Answer:
D
Step-by-step explanation:
This should be easy one unless you're making silly mistake like forgetting to take reciprocal of 
lets do it:
÷
first: we take the reciprocal of 3/2x now its
*
now just multiply top and bottom by using distributive method
this is your answer.
1. Consider the pyramid ABCDE in the figure 1 attached:
Each side of the square base equals

(units)
Area of 1 lateral side of pyramid ABCDE is

so the total lateral area is

(units squared)
and the total surface area is

(units squared)
2. Now consider the second figure KLMNP, Sydney's pyramid:
The lateral area is

so the total area of the second pyramid is

So 2 things can be said about the areas:
i) the lateral area of Sydney's pyramid is

times larger than the lateral area of the original pyramid.
ii) The total area of Sydney's pyramid is

units squared larger than the total area of the original pyramid.
