Answer:
1/4
Step-by-step explanation:
First, add up the marbles:
2 + 9 + 7 = 18
Multiply by 2 because you pick two:
18 × 2 = 36
Simplify:
9/36 = 3/12 = 1/4
Hope this helped.
Answer:
see explanation
Step-by-step explanation:
Given
2cosΘ -
= 0 ( add
to both sides )
2cosΘ =
( divide both sides by 2 )
cosΘ = 
Since cosΘ > 0 then Θ is in first and fourth quadrants, hence
Θ =
(
) = 
OR
Θ = 2π -
= 
solutions are Θ =
, 
5/10 is equal to 25/50
I ts because you multiply 5x5 to get 25 and do the same to the denominator so 10x5 is equal to 50 so 25/50 is the answer.
Answer:
m = 7.25
Step-by-step explanation:
8m + 7 - 5 = 60
Evaluate like terms.
8m + 2 = 60
Isolate 8m.
8m = 60 - 2
Evaluate.
8m = 58
Find m.
m = 58 ÷ 8
m = 7.25
Answer: 33 groups
Step-by-step explanation:
Number of people that signed for help = 130 people
Number of people that can join a group = 4.
Number of groups that will be formed will be:
= Number of people that signed for help / Number of people that can join a group
= 130/4
= 32.5
= 33 groups
Since there'll be a remainder of 2 people, they will form a new group making 33 groups.
