A bag contains only red and blue marbles. Yasmine takes one marble at random from the bag. The probability that she takes a red marble is 1 in 5. Yasmine returns the marble to the bag and adds five more red marbles to the bag. The probability that she takes one red marble at random is now 1 in 3. How many red marbles were originally in the bag?

What is the total height of the real Stanley Cup if this replica is on a 2:11 scale?

Answers

The height of the real Stanley cup will be 89.65 cm.

Step-by-step explanation:

Step 1:

The replica of the Stanley cup is on a 2: 11 scale. The replica is the 2 of the ratio while the real Stanley cup is the 11 on the ratio.

To determine how much bigger than the replica the real Stanley cup is we divide the ratio, (11)/(2) = 5.5.

So the real Stanley cup is 5.5 times larger than the replica. To determine the height of the real cup we multiplythe height of the replica by 5.5.

Step 2:

To determine the height of the real cup, we must determine the height of the replica.

The height of the replica = 3.5 + 2.9 + 1.5 + 8.4 = 16.3.

So the height of the replica is 16.3 cm.

The height of the real cup = 5.5(16.3) = 89.65.

The height of the real Stanley cup will be 89.65 cm.

Answers

$36 commission on a $400 dryer sale. Then the commission rate will be 0.09. Then the correct option is A.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

Mark procures $135 for selling a $1,500 fridge.

The commission rate remains constant. Then the commission rate is given as,

Commission rate = 135 / 1500

Commission rate = 0.09

Let's check all the options, then we have

A)  $36 commission on a $400 dryer sale. Then the commission rate is given as,

Commission rate = 36 / 400

Commission rate = 0.09

$36 commission on a $400 dryer sale. Then the commission rate will be 0.09. Then the correct option is A.

How do you get an odd perimeter for a rectangle? If you can, how oils you get a length and a width?

Answers

An odd perimeter can only happen if either the length or the width is a fraction with 1/2 in it, or both the length and the width have a 1/4 in it.
The length and the width are found using the regular means, but you will have to worry about fractions involved, so it can get kind of messy
