Answer:
cos A = 12/13
Step-by-step explanation:
TanC = AB/BC = 2.4
therefore
BC = AB/2.4
Pythagorean theorem
AC = √(AB² + (AB/2.4)²) = (13/12)AB
Cos A = AB/AC = AB / (13/12)AB = 12/13
So J is jelly beans and T is trail mix :)
so J= $3.50
T= $1.50
3 small boxes and 6 large boxes were sent to the retailer.
Step-by-step explanation:
Number of books held by small boxes = 30
Number of books held by large boxes = 40
Total books held by boxes = 330
Let,
x represent the number of small boxes
y represent the number of large boxes
According to given statement;
y = 2x Eqn 1
30x+40y=330 Eqn 2
Putting value of y from Eqn 1 in Eqn 2
Dividing both sides by 110
Putting x=3 in Eqn 1
3 small boxes and 6 large boxes were sent to the retailer.
