let's say that number is "x", so that is then the 100%.
if 150 is 25%, what is "x"?
Let’s count it.
I’m assuming that you have a regular deck of cards and that means 13 hearts and 13 kings.
You can pick any card of 52 with equal probability 1/52 for each.
So there are 52 opportunities of 1/52 probability to take any card from deck.
But you are looking only for 13 of hearts and for 13 of kings. That means your chance is (13 + 13) / 52 = 1/2 :)
The first triangle’s area is 48.75. But since you round it to the nearest tenth, it’s 48.7.
Use the formula a=1/2bh to find the area of a triangle.
A= 1/2• 13 • 7.5
A= 6.5• 7.5
A= 48.75 —-> 48.7 square inches.
Sorry, I can only do one because of homework, but make sure to use that formula! Hope this helped.
90% out of 105% which would be 0.85
24 ice-cream cartons in a box, and you have 13 boxes. Therefore, you do 24 times 13.
24 x 10 = 240.
3 x 4 = 12
(3 x 2 = 6) x 10 = 60.
240
+60
+12
=312
