ArbitrLikvidat [17]
The first thing we should know in this case is the meaning of the following acronyms:

 GPA = (a1 + a2 + a3 + a4) / 4
 Where,
 ai = represents each of the notes (i: 1,2,3,4)
 However, this is also an example of the following type of entry:
 GPA = AVERAGE (a1: a4)

Jake has 56 cupcakes to put into some cake tins. he puts the same number of cupcakes into each tin. 5 tins contain 35 cupcakes i
stiks02 [169]
Let's first come up with an equation that we can use to solve this problem.

Total Cupcakes= Cupcakes in each tin • the number of tins.

We are given the total number, and we want to find the number of tins and number in each tin now. So our equation looks like this.

56= cupcakes per tin • # of tins.

If we know that in 5 tins there are 35 cupcakes, and each tin has the same number we can divide 35 by 5 to find out there are 7 cupcakes in each tin. Now we have more info for our equation.

56 = 7 • # of tins.
We can divide the total number by the number in each tin, 56/7= 8.

Your answer is 8 tins.

I am Lyosha [343]

Answer:

First part = 2.

Time to land = 6 seconds.

Step-by-step explanation:

The object is at h = 0 when it land so

-5x^2 + 20x + 60 = 0

-5(x^2 - 4x)  = -60

-5[(x - 2)^2 - 4] = -60

(x - 2)^2 - 4 = -60/-5 = 12

(x - 2)^2 = 16.

Solving the above:

Take the square root of both sides:

x - 2 = 4

x = 2 + 4

x = 6 seconds
