I don't want the answer, I want to know how to do it. What is the ratio of 4/5 to 7/15?

Ostrovityanka [42]

Answer:

$\displaystyle 1\frac{5}{7}$

Step-by-step explanation:

$\displaystyle \frac{4}{5} \div \frac{7}{15} = \frac{4}{5} \times \frac{15}{7} = \frac{60}{35} = 1\frac{5}{7}$

15 Points!! Is this my teacher's fault? The math and the picture aren't making sense. The blue is my answer.

kogti [31]

Answer:

Your teacher is correct.

Step-by-step explanation:

So first we would have to find what A is equivalent to which is 48. This is because 180 - 132 = 48. Since we know that 132 is a supplementary angle, there has to be another supplementary angle that results in the sum of 180.

With this information in mind, we can create the expression:

2x + 4x + 48 = 180 (A triangle is equal to 180 degrees)

Now simply the equation:

6x + 48 = 180

6x = 132

6x/6 = 132/6

x = 22

Angle C = 44

Angle B = 88

The table below shows the squares of different numbers:

gogolik [260]

The table in Part A represents y as a function of x. This means that the value of Y is dependent on the value of X. The table can be represented by an equation that describes the relation of X and Y:
$y = x^{2}$ or $f(x) = x^{2}$
By substituting any value of X, you get a specific value of Y based from the given relationship, thus Y is a function of X.

For Part B, the value of f(150) is $470 and it represents the total cost for borrowing a rowboat for 150 hours. By substituting the value of x = 150 into the function, you get the total cost:
$f(x) = 20 + 3x \\ where \\ x = 150 \\ f(150) = 20 + 3(150) \\ f(150) =20 + 450 \\ f(150) = $ 470$
