What is 22.5% written as a fraction in simplest form?​
murzikaleks [220]

Answer:

9/40

Step-by-step explanation:

  • Write down the percent divided by 100 like this:

22.5/100

  • Multiply both top and bottom by 10 for every number after the decimal point:
  • As we have 1 digit after the decimal point, we multiply both numerator and denominator by 10, or, simply shift 1 decimal place to the right. So,

(22.5*10)(100*10)= 225/1000

  • Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(225,1000) = 25.

225 ÷ 25/ 1000÷25 = 9/40

The total number of marbles  times the probability of red marbles = number of red marbles

total * 7/10 = 42

Multiply each side by 10/7

total * 7/10 * 10/7 = 42*10/7

total

60

There are 60 marbles in the bag

Using complete sentences explain which function has the greatest y intercept f(x) = -6x-3 h(x)= 2 cos (x+ pi)-1
V125BC [204]

Answer:

They have the same y-intercept.

Step-by-step explanation:

The y-intercept occurs when x = 0  so for f(x):

y-intercept = f(0) = -6(0) - 3 = -3.

For h(x):

y-intercept = h(0) = 2 cos(0 + pi) - 1

= 2 cos pi - 1

= 2 *-1 - 1 = -3.

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 11 feet cubed.
asambeis [7]

9514 1404 393

Answer:

  V = (2/3)(11)

Step-by-step explanation:

The given cylinder has a height of 2r, so its volume is ...

  V = πr²(2r) = 2πr³

The volume of a sphere is given by ...

  V = 4/3πr³

Then the ratio of the volume of the sphere to the volume of the cylinder is ...

  (4/3πr³)/(2πr³) = (4/3)/2 = 2/3

So, the volume of the sphere is 2/3 times the volume of the cylinder:

  V = (2/3)(11)
