Answer:

Radius of Circle

radius = $\sqrt{(x2-x1)^{2} +(y2-y1)^{2} }$

radius = $\sqrt{(-3+2)^{2} + (-1 -1)^{2} }$

radius = $\sqrt{(-1)^{2} +(-2)^{2}}$

radius = $\sqrt{5}$

radius = 2.24

The radius of this circle is 2.24

Cir = 2 x pi * 2.24

Cir = 2 x 3.14 *2.24

Cir = 4.47 x pi

Cir = 14.04

Samuel is running a 3-mile race. He would like to finish the race in under 33 minutes. He has already run for 10. 5 minutes. The

photoshop1234 [79]

x < 22.5; Samuel has less than 22.5 minutes to finish the race in the estimated time.

<h3>What amount of time Samuel left for the race?</h3>

The given inequality is-

$10x < 33$

From here, we define the variable x.

x = Number of the minutes left for the race

From here we can find the value of x

We have then:

$x < 33-10.5$

$x < 22.5$

Hence, Samuel has less than 22.5 minutes to finish the race in the estimated time.

7. Marco is making beaded bracelets. Each

stiks02 [169]

One way to find the least common multiple of two numbers is to first list the prime factors of each number.

8 = 2 x 2 x 2

Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

2: three occurrences

3: one occurrence

So, our LCM should be

2 x 2 x 2 x 3 = 24.

So, Marco can buy, at the very least, 24 beads of each color to have equal colors of beads.

Drains and me are used to empty a swimming pool. Train eight alone can empty the pool in 4.75 hours. How long will it take train

nikdorinn [45]

<h2>Answer:</h2><h2>It takes 5.744 hours for drain B to empty the pool.</h2>

Step-by-step explanation:

Let drain A nad be are used to empty a swimming pool.

Given drain A alone can empty the pool in 4.75 hours.

When both A and B are open, it takes 2.6 hours.

The time taken by B to draint the pool = ?

$\frac{t+4.75}{4.75t} = \frac{1}{2.6}$

2.6 (t+4.75) = 4.75t

2.6t + 12.35 = 4.75t

t = 5.744 hours

It takes 5.744 hours for drain B to empty the pool.
