There are 9 number cards from 2 to 10 in a deck of cards.
(2-10) has one 9
(2-10) has one 9
(2-10) has one 9
(2-10) has one 9
There are 4 nines in a deck of 52 cards. We know that 4 x 9 = 36.
The chance or probability of taking out a 9 is (36/52).
Reducing this fraction to the lowest terms we get 9/13.
Answer:
5y
Step-by-step explanation:
subtract 8 from 3
You would eat 3/10 of the box because 3/4 times 2/5 is 3/10. Whenever you see the word "of" it means multiplication.
28 - 2.2x = 11.6x - 54.8
28 + 54.8 = 11.6x + 2.2x
82.8 = 13.8x
82.8 / 13.8 = x
6 = x
or x = 6
Step-by-step explanation:
5(tanx)^2 -2 +tanx=0
let tanx=y
5y^2 + y-2=0
y=0.5403 or y= -0.7403
tanx=0.5403
x=arctan(0.5403)
x=28.38°
or
tanx=-0.7403
x=arctan(-0.7403)
x=143.49°
