Answer:

He shouldn’t play.

Step-by-step explanation:

The least he can lose is 20 dollars, but there’s a chance of 30% that he will.

The MOST he can win is 50 dollars with a chance of 10%.

The odds are not in his favor. (The chance of losing is equal to the chance of winning, but the amount of money lost is higher than the amount won)

Michael's rock collection is 27% igneous rock. Half of his collection is sedimentary rock, while the rest is metamorphic rock. H
rjkz [21]

Answer:

23% of Michael's rock collection is metamorphic rock.

Step-by-step explanation:

We are given the following in the question:

Percentage of igneous rock in the collection = 27%

Percentage of sedimentary rock in the collection = 50%

Remaining rocks are metamorphic rock.

Total collection = 100%

Percentage of metamorphic rocks =

=100\%-(27\%+50\%)\\=100\%-77\%\\=23\%

Thus, 23% of Michael's rock collection is metamorphic rock.

If the diagonals of a parallelogram from right angles,then the parallelogram is the rectangle
geniusboy [140]

The statement above is false.


If the diagonals of a parallelogram form right angles, then the parallelogram is a rhombus (a rhombus is a quadrilateral with four equal side lengths).


Note* = by saying the statement is false is not saying that the scenario presented in the statement cannot occur. If the rectangle was a square, then its diagonals can form right angles since a square is also a rhombus. However, if a rectangle was NOT a square, its diagonals would not form right angles. A true statement is a statement where ALL cases fit the said requirement(s).


The statement can also be corrected by saying:

If the diagonals of a parallelogram are congruent, then the parallelogram is a rectangle.


All rectangles (even a square) have congruent diagonals, so this statement would be true.


Hope this helps!

Jeanie sells M&Ms out of her giant bag at 4 for 5 cents. The machine at the store sells you 9 for 25 cents. Which is the bet
Marina CMI [18]
Okay for problem 1 heres my explanation
So if you can get 4 bags for 5 cents so I multiplied 5 by 5 to get 25 cents and multiplied 4 by 5 and got 20 for 25 cents but the machine sells you 9 for 25 cents so if you get the m&ms from Jeanie you'll get more for your money if you get it from jeanie
Now problem 2
Now if tom sells 10 cards for 35 cents so theres a 5 cent difference for 2 more cards now 3 cents will be the most likley for the price for one of toms cards and toms price should have been 33 cents so your only being robbed of 2 cents not a big amount but we'll still look at the other guy 12 cards for 40 cents now if we look at how much toms cards will be if you bought 12 is only 39 cents 1 cent less than the other guy so in conclusion if you buy from Tom you get the better buy
Now problem 3
simple mutipily 19x4 and 76 cents the guys at the firework stands charge 85 for four so if you go to the hardware store and buy your fireworks there you get a better deal.
okay so im running out of time so someone else is gonna answer the last problem... sorry m8
