Answer:

135°

Step-by-step explanation:

The sum of interior angles in this rectangle is equal to 720

Two of the angles are right (has 90°)

so 4x + 180 = 720 subtract 180 from both sides

4x = 540 divide both sides by 4

x = 135°

a water wheel has a radius of 18 feet. The wheel is rotating at 10 revolutions per minute. Find the linear speed, in feet per

Yuri [45]

Answer:

The linear speed is $1,130.4\frac{ft}{min}$

Step-by-step explanation:

step 1

Find the circumference of the circle

The circumference is equal to

$C=2\pi r$

we have

$r=18\ ft$

$\pi =3.14$

substitute

$C=2(3.14)(18)$

$C=113.04\ ft$

step 2

Find the linear speed in feet per minute

we know that

The wheel is rotating at 10 revolutions per minute

Convert revolutions to feet

Remember that

One revolution is equal to the circumference of the circle

10 revolutions is equal to

$(10)113.04=1,130.4\ ft$

therefore

The linear speed is $1,130.4\frac{ft}{min}$

Find the solution(s) to 22 +57-3 = 0. Check all that apply.

irakobra [83]

Answer:

x = -3 and x = 1/2

Step-by-step explanation:

To find the solutions to

2x² + 5x - 3 = 0

we can use the quadratic formula, as follows:

$x = \frac{-b \pm \sqrt{b^2- 4(a)(c)}}{2(a)}$

$x = \frac{-5 \pm \sqrt{5^2- 4(2)(-3)}}{2(2)}$

$x = \frac{-5 \pm 7}{4}$

$x_1 = \frac{-5 + 7}{4}$

$x_1 = 0.5$

$x_2 = \frac{-5 - 7}{4}$

$x_2 = -3$
