Find the ratio of the known sides.

6/4 = 1.5

The larger triangle is 1.5 times larger than the smaller one.

Area is in square units, so to find the area of the larger triangle square the ratio and multiply that by the area of the known triangle.

1.5^2 x 40 = 90 square cm.

The number of mold cells doubles every 12 minutes. At this moment, there are x mold cells present on a piece of bread. Which of
lisabon 2012 [21]

Answer:

Step-by-step explanation:

Suppose that at time t_0 we have x mold cells. We are told that after 12 minutes the amount present is double. That is a t= t_0+12 we have 2x cells. Then, at t = t_0+24 we have (2x)*2 = 4x. We can continue as follows

t: t_0+36 we have (4x)*2 = 8x.

t: t_0+48 we have (8x)*2 = 16x

t: t_0+60 (one hour later) we have (16x)*2 = 32x.

So after one hour from now we have 32x cells.

To sell 300 notebooks and 120 pens quickly, a store decided to create two types of gift sets. one set is to include 2 notebooks
VikaD [51]

The store must sell 60 of each set each to obtain the biggest possible income

<h3>How to determine the number of each gift set?</h3>

The given parameters can be represented using the following table:

                        <u>Set 1        Set 2     Available</u>

Notebook         2                3         300

Pen                   1                  1          120

Selling price     8               11.5

Using the above data values, we have:

Objective function: Max P = 8x + 11.5y

Subject to:

2x + 3y ≤ 300

x + y ≤ 120

Next, we plot the graph of the above inequalities (see attachment)

From the attached graph, we have:

(x,y) = (60,60)

Hence, the store must sell 60 of each set each to obtain the biggest possible income
