Answer:
870.
Step-by-step explanation:
There are 30 choices of representatives. This leaves 29 choices for alternate representatives.
If one person gets elected for representative, there are 29 choices for an alternate representative.
This is the case if any of the 30 students get elected as representatives.
That means you can set it up as:
x*y where x is the choice of representatives and y is the choice of alternate representatives.
30 * 29, or 870.
Here is a visual example. Students a - dd are shown here.
a b c d e f g h i j k l m n o p q r s t u v w x y z aa bb cc dd
In this case, a has been chosen as class president. Any of the other 29 students could be a alternate, and then paired with a. This makes 29 total possible pairings. This is then repeated for the possibility of every student becoming a president, which creates 30*29.
Please tell me if this is wrong, I will try to make changes!

Spongebob and Patrick are selling kelp fries to fundraise for new jellyfishing nets. They sold
small and large sizes. Spongebob sold 3 small fries and 14 large fries for a total of $203.
Patrick sold 11 small fries and 11 large fries for a total of $220. Find the cost of each size of
fries.
a
Answer:
So, cost of small size is $7 and cost of large size is $13.
Step-by-step explanation:
Let cost of each small size - x, cost of each large size - y
By the question,
3x + 14y = 203
11x + 11y = 220
From the first equation, we get,
3x + 14y = 203
or, 3x = 203 - 14y
so, x = (203 - 14y)/3
Substituting x's value in second equation :-
11x + 11y = 220
or, 11 { (203 - 14y)/3 } + 11y = 220
or, {2233 - 154y}/3 + 11y = 220
or, { 2233 -154y + 33y} = 660
or, 2233 - 121y = 660
or, 121y = 2233 - 660
or, 121y = 1573
so, y = 1573/121
so, y = 13
Now,
As we know,
x = (203 - 14y)/3
or, x = ( 203 - 14 × 13)/3
or, x = (203 - 182)/3
so, x = 21/3
so, x = 7
So, cost of small size is $7 and cost of large size is $13.

One of the intermediate steps led to the equation 2x = 8.
Which of the following systems could have led to this equation?
3x - y = 15
x + y = 7
x + 3y = 24
- x - 3y = 16
4x + 2y = 14
x + y = 3
2x+2y = 8
- 2x - 2y=8
Answer:
(c) 4x + 2y = 14; x + y = 3
Step-by-step explanation:
The given equation will be the result of eliminating the y-variable from the system. When we do that for the different answer choices, we get ...
aAdd the two equations: (3x -y) +(x +y) = (15) +(7) ⇒ 4x = 22
bAdd the two equations: (x +3y) +(-x -3y) = (24) +(16) ⇒ 0 = 40
cSubtract twice the second from the first.
(4x +2y) -2(x +y) = (14) -2(3) ⇒ 2x = 8 . . . . the system we're looking for
dAdd the two equations: (2x +2y) +(-2x -2y) = (8) +(8) ⇒ 0 = 16

Using the Central Limit Theorem, it is found that each random sample must have at least 10 parents supporting the change and 10 opposing.

What is a triangle?A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.
Two similar solids have a surface area of 48ft^2 and 147ft^2 respectively.
If the volume of the smaller solids is 320ft^3.
Since the solids are similar, the ratio of the surface areas is equal to the square of the scale factor, k.
Thus, k2 = 147 / 48 , or k = 49/16 = 7/4
The ratio of the volumes of the solids is equal to k3, which gives:
V / 320 = (7/4)^3
where V is the volume of the larger solid.
V = 320 x (7/4)^3
= 1715 cubics in
