What is the radius of a circle in which a 30 degrees arc is 2 inches long

Mathematics
1 answer:
igomit [66]3 years ago
6 0

arc length = pi /180 * angle in degree * radius

2 = pi/180 * 30 *r

2 = pi/6 *r

multiply by 6/pi

12/pi =r

3.819718634 =r

Answer: r =3.82 inches

Jamal pays an initial fee of $50 and $4.00 for each audio book he downloads?
olganol [36]

Answer:

4x + 50 = y

Step-by-step explanation:

Since it is $4 for each audiobook, this means that it is the slope.

Since Jamal started with an initial fee, this makes it the y-intercept.

So the equation is $4 per audiobook = 4x, initial fee of $50 which makes the equation: 4x + 50 = y

<u>Y-intercept</u> is the starting number, in this case, the initial fee.

<u>Slope</u> is the rate at which a value is increasing, in this case, for each audiobook bought, $4 is spent

Use a table of signs to solve the inequality
bulgar [2K]

The interval of the provided inequality expression is -5/9 to the infinity [(-5/9),∞) using the table of signs to solve the inequality.

<h3>What is the inequality equation?</h3>

Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.

The inequality given in the problem is,

4x + \dfrac{5}{9} - 3x \geq 0

Simplify the equation first by adding the same terms,

4x + \dfrac{5}{9} - 3x \geq 0\\4x - 3x+ \dfrac{5}{9}  \geq 0\\x+ \dfrac{5}{9}  \geq 0\\x\geq-\dfrac{5}{9}

Now in this case, if the value x is ranges from -5/9 to infinity.

Thus, the interval of the provided inequality expression is -5/9 to the infinity [(-5/9),∞) using the table of signs to solve the inequality.

When diving, a bald eagle can reach a speed of 200 miles per hour. What is this speed in feet per second? Round to the nearest h
LenaWriter [7]

Answer:

A mile is equal to 5280 feet

You start off with

200 miles per hour

If you multiply 200 by 5280 you can find the speed in feet per hour

1,056,000 feet per hour

There are 60 minutes in an hour

If you divide 1,056,000 by 60 you can find the speed in feet per minute

So 17,600 feet per minute

Then if you divide that by 60 you can find the speed in feet per seconds

It is 293 1/3 or 293.333 feet per second.
