Answer:
24
/5
Step-by-step explanation:
The way I think about areas of sectors is a fraction of the pie. You know what percentage of the "pie" (in this case, circle) you want, because they give you the angle of the sector and you know a circle always has 360°. So technically, you're trying to find 48/360 th of the entire area (36). If you're using a calculator, it doesn't matter if you simplify the fraction, but if you're doing it by hand simplifying makes everything a lot easier.
The equation will be:
Area = 24/180 × 36
= 2/15 × 36
= 72/15
= 24/5
I hope this helped! Also, in Khan Academy, when you get an answer wrong/right, you can view their explanation by clicking "hint" or sometimes "see how we did it" shows up.
Lo siento :( perdonameeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee soy Principiante
If two triangles are similar, that means their side lengths are proportional, so we get the equation
Thus x = 13.6.
Hope that helped!

Answer:
a) 0.5
b) 0.75
c) 0.307
Step-by-step explanation:
We are given the following information in the question:
Number of cards in a deck = 52
Formula:
a) P(Heart or Diamond)
Total number of hearts and diamonds in a deck = 13 + 13 = 26
P( Heart or Diamond) =
b) P(Heart or Diamond or Spade)
Total number of hearts, diamonds and spades in a deck = 13 + 13 + 13 = 39
P( Heart or Diamond or Spades) =
c) P(10 or Spades)
Total number of spades in a deck = 13
Number of 10 in a deck = 4
P( 10 or Spades) =
