3. The rectangle below has an area of 297 in. Find the length of the diagonal.

saul85 [17]

9514 1404 393

Answer:

29.15 in

Step-by-step explanation:

The area of a rectangle is given by the formula ...

A = LW

Filling in the given information, we can find the missing side length.

297 in² = (27 in)h

h = (297 in²)/(27 in) = 11 in

The length of the diagonal can be found from the Pythagorean theorem.

d² = 27² + 11² = 729 +121 = 850

d = √850 = 5√34 ≈ 29.15476

The length of the diagonal is about 29.15 inches.

If 2/3 of the distance from the y-axis to point A (−30, −45) is equal to 1/4 of the distance from the x-axis to point B(a, a), w

Yuliya22 [10]

The value of a is 80

Step-by-step explanation:

The distance of a point $(x_0,y_0)$ from the y-axis can be written as

$d_y = |x_0|$

because the x-coordinate of the y-axis is zero.

Similarly, the distance of a point $(x_0,y_0)$ from the x-axis can be written as

$d_x=|y_0|$

Since the y-coordinate of the x-axis is zero.

In this problem:

- The distance of the point A (−30, −45) from the y-axis can be written as

$d_A = |-30|=30$

- The distance of point B (a,a) from the x-axis can be written as

$d_B = |a| = a$

Since $a>0$ .

We are told that 2/3 of the distance from the y-axis to point A (−30, −45) is equal to 1/4 of the distance from the x-axis to point B(a, a), which means

$\frac{2}{3}d_A = \frac{1}{4}d_B$
