Because 6 * 8 + ( - 2 )* 24 = 48 - 48 = 0 , the vectora u and v are orthogonal ;
Two vectors are orthogonal if their dot product is zero.<span />
Answer:
x=97
Step-by-step explanation:
Answer:
x= 4 or -10
Step-by-step explanation:
b. 8 because Total Pieces Sold=60
Pieces contributed by the cafeteria=20
Pieces contributed by the clubs=x
We can solve this problem by creating an equation to relate these terms:
Total Pieces Sold= (pieces contributed by the cafeteria) + (pieces contributed by the clubs)
Our equation is therefore: 60=20+x. We solve for x:
60-20=x
40=x
This means the clubs contributed 40 pieces. To find out how many pies that equals, we can use the relationship:
(40 pieces)/(y pies) = (5 pieces)/(1 pie). Solve for y:
(1)(40)=(5)(x)
(40/5)=8
