The cost of cleaning up pollution in a stream is given by C = 37000 100−p , where C is the cost in dollars to clean p percent of

the stream. (For instance, when p is 20, then the formula will calculate the cost to clean up 20 percent of the stream.) a) p must be greater than or equal to zero and p must be less than what number? [3pts]

Answer:

  100

Step-by-step explanation:

If we assume your equation is ...

  C=\dfrac{37000}{100-p}

then the value of C is undefined for p = 100. p must be less than 100.

90 percent as a fraction in simplest form
inysia [295]
Whenever a number is followed by percent, you can turn it into a fraction by simply moving the decimal places two places to the left:

90.0 % becomes .90 

As a fraction, this is 90 over 100. To reduce it to its simplest form, divide by 10:

Kenneth wants to sew a tent, including the bottom so that it is entirely enclosed. He has a rectangular piece of canvas with dim
Vadim26 [7]

Based on the calculations, the depth of tent is equal to 12 feet.

<h3>How to calculate the depth of the tent?</h3>

Based on the diagram (see attachment) and information provided, we can logically deduce the following parameters (points):

  • Triangle ABC is an isosceles triangle (AB = AC).
  • The front and back of the triangle are identical triangles.
  • Side AD is perpendicular side BC.
  • CD is the midpoint of BC i.e CD = BC/2 = 6/2 = 3 feet.

Next, we would determine the height of the right-angled triangle (ADC) by applying Pythagorean theorem:

AC² = AD² + DC²

AD² = AC² - DC²

AD² = 5² - 3²

AD² = 25 - 9

AD² = 16

AD = √16

AD = 4 feet.

Also, we would determine the area of the triangle (ABC):

Area = 1/2 × b × h

<u>Where:</u>

  • b is the base area.
  • h is the height.

Substituting the given parameters into the formula, we have;

Area = 1/2 × 6 × 4

Area = 12 feet².

Depth of tent = 3 × height of ADC

Depth of tent = 3 × 4

Depth of tent = 12 feet.
