It is 21 1/2. Leave 21 as a whole number. Now you have 0.5. 0.5 becomes 1/2 since any number in the tenths place is going to be something over /10.

The rear wheel of a lawn tractor has a 20-inch radius. Find the angle (in radians) through which a wheel rotates in 23 seconds i

Minchanka [31]

Answer:

263.12 radians

Step-by-step explanation:

The length of the rear wheel is given by:

$L=2\pi r\\L=40\pi$

The distance traveled by the lawn tractor in 23 seconds is:

$d=13\frac{miles}{hour} *63360\frac{inch}{miles}*\frac{1\ hour}{3600\ seconds}*23\ seconds\\ d=5,262.4\ inches$

The angle through which a wheel rotates is given by:

$A=\frac{d}{L}*2\pi \\A=\frac{5,262.4}{40\pi}*2\pi\\A=263.12\ radians$

The wheel rotates through a 263.12 radians angle.

what is the slope of a 5-foot high platform that begins at ground level 10 feet from the base of the platform?

Sladkaya [172]

Answer:

11.2 feet

Step-by-step explanation:

Given: Height of platform (Opposite)= 5 foot

Distance of slope from the base of platform (adjacent)= 10 feet

Picture drawn to show the measurement.

Lets find the length of slope.

Using the Pythagorean theoram.

$hypotenous^{2} = opposite^{2} + adjacent^{2}$

Subtituting the value in the formula.

$hypotenous^{2} = 5^{2} + 10^{2}$

⇒ $hypotenous^{2} = 25 + 100$

⇒ $hypotenous^{2} = 125$

Putting square root on both side

We know, √a²= a

⇒ $hypotenous = \sqrt{125}$

∴ hypotenous= 11.18 $\approx 11.2 \ feet$

Hence, the slope is 11.2 feet
