Elenna [48]

Answer:

x*(2/3)=y

y*1.5=x

Step-by-step explanation:

There is 2/3rds the amount of sodium in the new one, y. If you multiply the odl one, x, by 2/3, you'll have the amount in the new one. Because half of 2/3rds is 1/3, if you multiply the new one by 1.5, you'll end up with 3/3, or 1, which is the amount in the old one.

Solve the triangle.

saw5 [17]

Answer:

Step-by-step explanation:

because <u>c</u> is shorter than<u> a</u> we know C is a smaller angle than A

so the first choice is out.

use the law of cosines to find b

$b^{2}$ = $a^{2} +c^{2} -2*a*c*cos(B)$

$b^{2}$ =1681+400-1326.787871

$b^{2}$ = 754.21219

b= $\sqrt{754.21219}$

b= 27.46292

so the last choice looks good
