30 foot tree = 18 foot shadow
26 foot tree = x foot shadow

(Cross Multiply)

30 * x = 26 * 18
x = 468 / 30
x= 15.6

26 foot tree casts a 15.6 foot shadow.

A 1,000 mL solution of acetic acid contains 26 mL of pure acetic acid. Find the percent concentration of this solution.

Mrac [35]

Given:

Total solution : 1000mL

Pure acetic acid = 26mL

To find:

The percent concentration of given solution.

Solution:

We know that,

$\text{Percent concentration}=\dfrac{\text{Pure acetic acid}}{\text{Total solution}}\times 100$

Putting the given values, we get

$\text{Percent concentration}=\dfrac{26}{1000}\times 100$

$\text{Percent concentration}=\dfrac{26}{10}$

$\text{Percent concentration}=2.6$

Therefore, the percent concentration of this solution is 2.6%.

A rancher has 1000 feet of fencing in which to construct adjacent, equally sized rectangular pens. What dimensions should these

rosijanka [135]

Answer:

The dimensions that will maximize the enclosed area of the pen is 250 ft by 250 ft

Step-by-step explanation:

we have the perimeter as 1000

So the sum of the lengths will be

1000/2 = 500

The dimensions that will maximize these pens will be such that they will have equal values

Mathematically, that will be 500/2 = 250 by 250
