Answer:
Step-by-step explanation:
When 2 lines are perpendicular, their slopes are negative reciprocals of one another. Here, if the slope of A is -1/2, the slope of B is +2/1, or just 2.
Answer:
you have to add each
Step-by-step explanation:
We know that there are 15 children altogether
We know that the number that voted for B+R is double the number of students voted for G+Y
B+R = 2(G+Y)
Think of two numbers that add up to 15, one number is twice of the other number.
For example, 6 and 12.
12 is double of 6 but 6 + 12 doesn't give 15
So, think again
for example 5 and 10
10 is double of 5 and 5+10 does give 15
So, the number that voted Red and Blue is 10 and the number that voted Yellow and Green is 5
(A) The cost would be $6,600 because 100 guests would be $35 * 100 which is $3,500. Then, add that amount to the cost of the venue. $3,100 + $3,500 = $6,600.
(B) C = $3,100 + (n - 50) * 35
(C) 118 guests
Answer:
If the coin is fair, then the odds of getting heads or tails should be equal, 12. Then 3 tosses of tails will have a chance of 12⋅12⋅12=18.
