Answer:
21 ft
Step-by-step explanation:
The area of a parallelogram is given by
A = bh
336 = 16*b
Divide each side by 16
336/16 = 16b/16
21 =b
Answer:
y=3 x= -5/2
Step-by-step explanation:
simultaneous equations
2x + 4y = 7 ------ eq 1
-2x + 3y = 14 --------eq2
(different signs add)
(eq 2 + eq 1)
-2x +(-2x) = 0
4y+3y = 7y
7+14 = 21
7y= 21
(divide both sides by 7)
y= 21/7= 3
2x + 4(3) = 7
2x+ 12=7
2x = 7-12
2x = -5
x= -5/2
A) 26.6° I'm assuming that there's a typo in the problem and that the equation is y = 1/2 x. If that's the case, then the tangent of the desired line is 1/2, and the arc tangent of 0.5 is 26.56505118 which rounds to 26.6° which in turn nicely matches option "A".
Let cranberry juice be x.
Let citrus fruit juice be y.
x + y = 630
x + 0.1y = 630*0.23
Solving this yields,
x = 91
y = 539
Therefore, you need 91 oz of pure cranberry juice and 539 oz of fruit juice.
Hope this helps.:)
