Answer:
48 cookies were sold in total.
Step-by-step explanation:
5:1 is the ratio of raisin cookies to oatmeal cookies, and 40 raisin cookies were sold. Meaning, 40:?.
To find the number of oatmeal cookies you divide 40 by 5, which gets 8. This means that the original ratio is multiplied by 8 to get the current ratio for the amount if cookies. 5(8) : 1(8) = 40:8. There are 40 raisin cookies and 8 oatmeal cookies. 40+8=48. There were 48 cookies sold in total.
Answer: u.(v+w) = -20
Step-by-step explanation:
Given;
u = -i+j
v = 10i-2j
w = -8j
v+w = 10i-2j +(-8j)
v+w = 10i-10j
u .(v+w) = (-i+j).(10i-10j)
= -1×10 + 1 ×-10
= -10-10
u.(v+w) = -20
If they are all in a line then we can find the equation of their line using: y = mx + b
First find m using points (2,5) and (3,3)
m = (5-3)/(2-3) = 2/-1 = -2
Now using (3,3) and m= -2 to solve for b:
3 = -2(3) + b
3 = -6 + b
9 = b
So our equation is y = -2x + 9
That is the solution for question b)
Now to find the mystery point, solve:
1 = -2x + 9
-8 = -2x
4 = x
So our mystery point is (4,1)
So for part a) the answer is k = 4
