The two angles are vertical angles and are identical.

Set them equal to each other and solve for y:

5y = 115

Divide both sides by 5:

y = 115/5

y = 23

Answer: y = 23 degrees.

Point B has coordinate B(1, -1).

Answer: B' is (3, -3)

Step-by-step explanation:

When we have a point with coordinate (x, y) and we do a dilation (around the center) with a scale factor of A, the coordinate of the new point will be:

A*(x,y) =(A*x, A*y)

Here our point is (1, -1) and the factor is 3, so the new point will be:

(3*1, 3*-1) = (3, -3)

Alloy #13 contains 7% gold, if means that if we need 2.7kg of this alloy, we will have to use a certain amount of gold. Multiply the percent of gold times the mass of alloy to find how much gold we need:

$2.7kg\cdot7\%=0.189kg$

It means that we need 0.189kg of gold.

The alloy we have contains 21% of gold. That means that for every 100kg of alloy there are 21kg of gold, use this ratio to find the mass of alloy we need:
