Option B: 21.3 in is the length of AB

Explanation:

The equation is $\sin 25^{\circ}=\frac{9}{c}$

To find the length of AB, let us equate,

$c=\frac{9}{\sin 25^{\circ}}$

Substituting the value for sin 25°, we get,

$c=\frac{9}{0.4226}}$

Dividing the values, we have

$c=21.3$

Thus, the length of AB is 21.3 in.

The correct answer is Option B.

A 37-inch piece of steel is cut into three pieces so that the second piece is twice as long as the first piece, and the third

Gennadij [26K]

1st piece = x

2nd piece = 2x

3rd piece = 4x+2

x + 2x +4x +2 = 37

7x+2 =37

7x = 35

x = 35/7 = 5

1st piece = 5 inches

2nd piece = 10 inches

3rd piece = 22 inches

Three ways to write 18/6

const2013 [10]

One way to write 18/6 is to compute 18/6 to be the whole number of a quotient that is equal to. Another way to write 18/6 is to write it as an improper fraction that's reduced. One more way to write 18/6 is as a decimal. Note how all of these ways of writing the same expression are all equal to writing one same value, and it's the WAY in which you modify what you're writing.

Based on the graph, which equation represents the relationship between the height of trees (y) and the amount of rainfall (x)?

slega [8]

Given:

Given that the graph that shows the amount of rainfall( in centimeters) and the height of the trees( in meters)

We need to determine the equation that represents the relationship between the height of trees(y) and the amount of rainfall(x).

Slope of the equation:

The slope can be determined using the formula,

$m=\frac{y_2-y_1}{x_2-x_1}$
