Width of the rectangle.

1 answer:

4 0

I assume we have to begin with the triangle. Applying the Pyth. Thm.,
(x)^2 + (7y)^2 = (3x)^2, so that (7y)^2 = (3x)^2 - (x)^2, or 8x^2.

If (7y)^2 = 8x^2, then 7y = sqrt(8x^2) = 2sqrt(2)x. This is the width of the rectangle, i. e., width 7y = 2sqrt(2)*x.

Mr. Yueng graded his students’ math quizzes.

Artyom0805 [142]

For this case we must solve the following equation:

$x ^ 3 = 22$

If we apply cubic root to both sides of the equation, then we eliminate the exponent on the left side:

$\sqrt [3] {x ^ 3} = \sqrt [3] {22}\\x = \sqrt [3] {22}$

That is the exact solution of the equation. Its decimal solution is given by:

$x = \sqrt [3] {22} = 2.8020$

ANswer:

The solution to the equation is $x = \sqrt [3] {22} = 2.8020$

How many sides does a regular polygon have if the measure of one of it's interior angles is 144?

butalik [34]

Each Interior Angle = 180° - (360 / sides)
144 = 180 - (360 / sides)
(360 / sides) = 36
sides = 360 / 36
sides = 10
It is a decagon.

What does 3/4 x 24 = ?

IrinaK [193]

Well, 1/4 of 24 gets us 6 (since 24 = 6 x 4), so <em>3/4 </em>should get us 6 × 3 = 18.
