Plz pick one of the ones shown: 1. rachel has 30 pounds of a mixture of candy that sells for $1.00/lb. if lollipops sell for $0.95/lb and caramel candies sell for $1.10/lb. how many pounds of lollipops are in the mixture? 2.if the product of two numbers is 14 and one of the numbers is 3 ½ times the other, then what is the sum of the two numbers? 3.given: ab≅bc and ae = 10 in, m∠fec = 90° m∠abc = 130°30’ find: m∠ebc, ac m of angle ebc= ?

I am doing with Question Number 2

Let the two numbers be 'x' and 'y'.

According to the question, the product of two numbers is 14.

So, xy=14 (Equation 1)

Now, one of the numbers is 3 ½ times the other.

So,

(Equation 2)

Substituting the value of 'x' from equation 2 in equation 1, we get

So, y= 2 and -2

So, and

x=7 and -7

Numbers are 2,7 and -2,-7.

Sum of numbers 2 and 7 = 9

Sum of numbers -2 and -7 = -9.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
