The shaded region has an area of 12 while the whole thing is 50 mutiply both by 2 to get the area of the shaded region and the whole thing by 100 After that subtract 24 from 100 and you get a 76 percent chance that you will randomly select an area in that box that isn't shaded.

There are 12 blue marbles and 8 red marbles. find the probability of selecting one item
Diano4ka-milaya [45]

Answer:

selecting one item? If you mean each color:

40% chance for a red marble / 2/5 chance

60% chance for a blue marble / 3/5 chance

Step-by-step explanation:

Because there are 12 blue marbles and 8 red marbles, we would total them to see how many marbles there are in total. There are 20 in total, but to find the probability, if we put all 20 marbles in a bag (blue and red), and we picked a marble at random, there are 8 red marbles and 12 blue marble in that bag. The probability that I will choose red marbles is 8/20 (or 8 red marbles out of 20 total marbles), and for blue marbles, it would be 12/20 (or 12 blue marbles out of 20 total marbles). Simplify both expression to 2/5, and 3/5 respectively. Finally, if you need percentage, just multiply the denominator by 5 to get it to a hundred, and do the same to the numerator. This way you don't change the value of the expression.

Virginia beach is about 20 miles wide and 28 miles long. if one inch of rain falls there during a daily rain shower, how many cu
S_A_V [24]
In this question, you are given the width( 20 miles), the length(28 miles) and the height( 1 inch). You are asked to count the rain water volume which was going with formula length x width x height. But the unit asked is ft, so you need to convert them all. The calculation would be:

Water volume= length x width x height
Water volume= 20 miles x 5280ft/miles x 28 miles x 5280ft/miles x 1inch x 1ft/12inch
Water volume = 1300992000 cubic ft.

Ashley uses 1/4 package of raisin for a fruit cake. She then uses 1/9 of the remainder for muffins. What fraction of the package
Flura [38]
\text {Fruit cake = } \dfrac{1}{4}

\text {Raisin left = } 1 -  \dfrac{1}{4} = \dfrac{4}{4} - \dfrac{1}{4} = \dfrac{3}{4}

\text {Muffins  = } \dfrac{1}{9}  \times  \dfrac{3}{4} =  \dfrac{3}{36} =  \dfrac{1}{12}

\text {Raisin left = } \dfrac{3}{4}  - \dfrac{1}{12} =\dfrac{9}{12}  - \dfrac{1}{12} = \dfrac{8}{12}  -= \dfrac{2}{3}

Answer: She has 2/3 of the package left.
