Answer:

Step-by-step explanation:

300 - 300(x/100) = 250

30000 - 300x = 25000

-300x = -5000

x = 16,66 %

Or

value of discount:

$300 - $250 = $50

x : 100 = 50 : 300 =

x = 5000 / 300 = 16,66%

What is the area of the figure if x = 25 cm and y=20 cm?<br> Use 3.14 to approximate it.
Akimi4 [234]

The area of the circle is 6,358.5cm²

<h3>Area of the circle</h3>

The formula for calculating the area of a circle is expressed as;

  • A = πr²

r is the radius = x + y

r = 25 + 20 = 45cm

Substitute the given parameters into the formula to have:

A = 3.14(45)²

A = 6,358.5cm²

Hence the area of the circle is 6,358.5cm²

Ms. Moneyhun's son, Sam, just learned to crawl. He can crawl 20 ft in one minute. How many feet can Sam crawl in one hour? (Hint
almond37 [142]

Answer:

1200 ft in one hour

Step-by-step explanation:

The ratio of Sam crawling 20 ft in one minute can be written as:

20:1

Multiply the ratio by 60 to get the minutes to 60 minutes, because there are 60 minutes in an hour:

 20    :    1

×60     ×60

To get:

1200:60  ⇒  This means Sam can crawl 1200 ft in 60 minutes, which is the same as 1200 ft in one hour.

<em>Hope this helps!</em> :)
