Answer:
The ratio is 6:2:1.
Step-by-step explanation:
Let's denote:
Blue counter b
Red counter r
Yellow counter y.
There is given
r=3b (three times more red as blue) [1]
and
b=2y (twice more blue as yellow.) [2]
Now, replacing [2] to [1] gives
3*2y=r
6y=r.
Hence, the ratio is 6:2:1, because r=6y and b=2y.
Let's start his with some trigonometry
Cos60=x/30
X=15
Now we can use Pythagorean therom
15^2+b^2=30^2
B(y)= 25.98
Answer:
1/24
Step-by-step explanation:
two coins each have a 1/2 probability of landing on heads so we multiply
1/2 x 1/2 = 1/4 probability of getting heads twice
we have a 1/6 chance of landing on a 4
so we multiply 1/6 x 1/4
which equals 1/24
Answer:
(2.9)+(2.7)=32 I think at is the answer
Answer:
A and B
Step-by-step explanation:
using the law of exponents
•
=
, hence
=
→ A
note that (- 3)² = 9 = 3², hence
= (3²)³ =
→ B
