To determine the area of the shaded region, you must
1: find the area of the whole rectangle
2: find the area of the non-shaded rectangle inside
3: subtract the non-shaded rectangle from the whole rectangle.

This is easier than you think.

The area of a rectangle is l x w, right?
Well, you have two rectangles: The rectangle that is the whole of the picture, and the tiny rectangle inside the shaded area.
So the big rectangle:

A = 10 x 14 5/8
    = 146.25
The insdie rectangle:
A = 5 x 2 1/2
   = 12.5

Now take the small one away from the large one:
146.25 - 12.5 = 133.75
Or, to put it in the same way as the question:
133 3/4 inches²

Ignacio shares 2.1 liters of water equally into 7 containers. How many milliliters are in each container?
Stella [2.4K]

Answer: 300 ml

Step-by-step explanation:

First and foremost, we should note that:

1000 milliliters = 1 liter

Therefore, 2.1 liters = 2.1 × 1000 = 2100 millimeters.

Therefore, since the liters of water is divided into 7 containers, the vlaue in each container will be:

= 2100 millimeters / 7

= 300 millimeters

Myra is a scientist and needs 45 gallons of a 16% acid solution. The lab is currently stocked only with a 20% acid solution and
asambeis [7]

Answer:

The volume of the solution with 20% acid is 27 gallons and the one with 10% acid is 18 gallons

Step-by-step explanation:

Myra needs to mix "x" gallons of the solution with 20% and "y" gallons of the solution with 10%. The volume of the final solution must be 45 gallons, therefore:

x + y = 45

The concentration of acid of the final solution is:

0.2*x + 0.1*y = 45*0.16

0.2*x + 0.1*y = 7.2

Therefore we have a system of equation:

x + y = 45

0.2*x + 0.1*y = 7.2

We need to multiply the first equation by -0.1:

-0.1*x -0.1*y = -4.5

0.2*x + 0.1*y = 7.2

We now sum both equation:

0.1*x = 2.7

x = 2.7/0.1 = 27 gallons

y = 45 - 27  = 18 gallons
