Answer:
a) 3/13
b) 1/2
Step-by-step explanation:
a) In a deck of 52 cards there are 4 Kings, 4 Queens and 4 jacks. So the probability of drawing those cards is (4+4+4)/52 = 12/52 = 3/13.
b) 1/2 because the numbers greater than 3 on a dice is 4, 5, and 6 which is half of the available options.
Answer:
A = 38°
Step-by-step explanation:
We are going to use cosine law to find angle A where
a = 4.7
b = 3.9 m
c = 2.9 m
or
cos A = [(4.7)^2 + (3.9)^2 - (2.9)^2]/2(4.7)(3.9)
= 28.89/36.66
= 0.788
A = arccos(0.788) = 38°
Answer:
A. V= area of base x height 1/3
(20x15)x30x1/3= 3000cm
B.65cm
C.CTCN is the angle between
tan<TCN= TN/NC=12/5
=67.380
D. 10\sqrt(10)
e.tan<TMN=TN/MN=3
<TMN=71.57
Answer:
Its volume is 2 times the original volume.
Step-by-step explanation:
It cant be the first 2 because you are making it bigger, not smaller. and it cant be the last one because you are only doubling one of the parts.
Answer:
37 inches
Step-by-step explanation:
The formula for diameter when you have the circumference is D =C / pi
So, we go 116.18 / 3.14, and we get 37 inches for the diameter of the tire.
