What two numbers add up two 40 but multiply to get 100
DerKrebs [107]

The two numbers are illustrations of system of equations

The two numbers are 2.7 and 37.3

<h3>How to determine the two numbers?</h3>

Let the numbers be x and y.

So, we have the following equations

x + y = 40

xy = 100

To determine the value of the variables, we simply plot the graph of both equations

From the graph, we have the following result

(x,y) = (2.7, 37.3)

Hence, the two numbers are 2.7 and 37.3

The ratio of the area of ∆ABC to the area of ∆DEF is; 1:100.

<h3>What is the ratio of the area of ∆ABC to the area of ∆DEF?</h3>

Since, a major criterion for similarity and congruence of triangles is that the ratio of corresponding sides are equal.

On this note, since the task content suggest that the ratio of the perimeters is; 1:10, it follows from conventional mathematics that the ratio of their areas is given as; 1²:10²; 1:100.

The level of a lake was 8 inches below normal. It decreased 1
solmaris [256]

Answer:

-9\dfrac{5}{8} inches.

Step-by-step explanation:

The level of a lake was 8 inches below normal.

Now, it is given that the water level decreases 1\dfrac{1}{4} = 1.25 inches in June and 2\dfrac{3}{8} =2.375 inches more in July.

Therefore, the new level of water with respect to the normal level will be  

= - 8 - 1.25 - 2.375  

= - 9.625 inches

= -9\dfrac{5}{8} inches. (Answer)
