Answer: $3510

Step-by-step explanation:

Fro th question, Alice, Bryan and Cindy share the cost of renting an apartment in the ratio 3:6:4 respectively and we.are informed that Alice pays $810 monthly.

Alice ratio = 3

Bryan's ratio = 6

Cindy's ratio = 4

Total ratio = 3+6+4 = 13

Since Alice has a ratio of 3, this means that Alice pays 3/13 of the total monthly rent. Let the total rent be x. Therefore,

3/13 of x = 810

3/13 × x = 810

3x/13 = 810

3x = 810 × 13

3x = 10530

x = 10530/3

x = 3510

Therefore, the monthly rent is $3510

Find the value of X. Round to the<br> nearest tenth. <br> 7.4in <br> 2.4in<br> x

Darya [45]

Answer:

4.4 inches

Step-by-step explanation:

Here, we are interested in calculating the value of x.

Mathematically, a line that comes from the center of the circle and extends to a chord, divides the chord into two equal parts.

This means what we have is a right angled triangle with the radius being the hypotenuse, the half of the length of the chord as the other side of the triangle.

3.7 is half the length of the chord i.e 7.4/2

Thus;

using Pythagoras’ theorem

x^2 = 2.4^2 + 3.7^2

Pythagoras’ posited that the square of the hypotenuse is equal to the sum of the squares of the other two sides of the triangle.

Thus;

x^2 =5.76 + 13.69

x^2 = 19.45

x = √(19.45)

x = 4.41 inches which is 4.4 inches to the nearest tenth
