Mathematics
1 answer:
k0ka [10]2 years ago
4 0

Answer: 5/16

Step-by-step explanation:

For this question, note that:

\sqrt{16}=4\\ \\ \sqrt{25}=5 \\\\\sqrt{81}=9\\\\\sqrt{144}=12\\\\\sqrt{225}=15\\\\\sqrt{729}=27

This means we can rewrite the given expression as:

\left(\frac{15}{27}-\frac{5}{12} \right) \div \frac{4}{9}\\\\=\left(\frac{5}{9}-\frac{5}{12} \right) \div \frac{4}{9}\\\\=\left(\frac{(5)(12)-(5)(9)}{(9)(12)} \right) \div \frac{4}{9}\\\\=\frac{15}{108} \div \frac{4}{9}\\\\=\frac{5}{36} \div \frac{4}{9}\\\\=\frac{5}{36} \times \frac{9}{4}\\\\=\frac{45}{144}\\\\=\boxed{\frac{5}{16}}

Kelsey is putting on sunscreen. She uses 3 ml to cover 45cm to the power of 2 of her skin. She want to know how many milliliters
Artemon [7]

Answer: She would require 16 ml cover 240cm^2 of her skin

Step-by-step explanation:

Let m represent the milliliters of sunscreen required to cover her skin.

Let a represent the area of her skin that was covered. She assumes the the relationship between milliliters of sunscreen and the area is proportional. Introducing the constant of variation, k, the expression becomes

m = ka

She uses 3 ml to cover 45cm^2 of her skin. Therefore,

3 = k × 45

k = 3/45 = 1/15

The expression becomes

m = a/15

The milliliters of sunscreen that Kelsey needs to cover 240cm to the power of 2 of her skin would be

m = 240/15

m = 16 ml

xxMikexx [17]

9514 1404 393

Answer:

  x = 8

Step-by-step explanation:

In an isosceles right triangle, the side length ratios are ...

  1 : 1 : √2 = x : x : 8√2

The latter ratios will match the first ratios when x=8.

__

That is, x = (8√2)/(√2) = 8.

Select the correct answer. robin randomly selects a number between 1 and 20. what is the probability that the number selected is
Vlada [557]

The probability that the number selected is the square of a natural number will be  \frac{1}{5}.

<h3 /><h3>What is probability?</h3>

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1.

Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

P is the probability

F(E) is the favorable event

T(E)is the total event

The probability is found as;

\rm P = \frac{F(E)}{T(E)} \\\\ \rm P = \frac{4}{20)} \\\\ \rm P = \frac{1}{5}

Hence the probability that the number selected is the square of a natural number will be  \frac{1}{5}.
