Beatrice pushes with a force of 40N . how can you you determine if Beatrice is doing work on the box ?

OLEGan [10]

The results of her effort can be grouped
into two general categories:

<u>Category #1:</u>
The box does <u>not</u> move.
<u>No</u> work is done.

<u>Category #2:</u>
The box <u>does</u> move.
Work <u>is</u> done.

Write an<br> i explicit formula for an, the nth term of the sequence 200, 40, 8, ....

Ugo [173]

Answer:

$T_n = 200 * (\frac{1}{5})^{n-1$

Step-by-step explanation:

Given

$Sequence: 200,40,8$

Required

The nth term

The given sequence is a geometric sequence.

So, first we identify the first term

$a = 200$

Calculate common ration

$r = \frac{40}{200}$ or $r = \frac{8}{40}$

$r = \frac{1}{5}$

So, the nth term is:

$T_n = ar^{n-1$

$T_n = 200 * (\frac{1}{5})^{n-1$

You are making cookies for a party. The ratio of Cookie Tray A to Cookie Tray B to Cookie Tray C is 2 : 3 : 4. If you need to ma

Elenna [48]

Given that the ratio of three trays is A : B : C = 2 : 3 : 4

Let us consider the common factor among the number of trays be "x".

If we need to make a total of 171 trays, then the equation of sum of trays would be :-

Type A + Type B + Type C = 171

2x + 3x + 4x = 171

9x = 171

x = $\frac{171}{9}$ = 19

So we have following number of trays :-

Number of type A trays = 2x = 38 trays.

Number of type B trays = 3x = 57 trays.

Number of type C trays = 4x = 76 trays.

Now if each tray contains 20 cookies, then we would have following arrangements :-

Cookies in type A trays = 38×20 = 760 cookies.

Cookies in type B trays = 57×20 = 1140 cookies.

Cookies in type C trays = 76×20 = 1520 cookies.
