A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is

Scorpion4ik [409]

Answer:

26 ounces of 55% solution
104 ounces of 80% solution

Step-by-step explanation:

Let x represent the quantity of 80% solution. Then 130-x is the amount of 55% solution. The total amount of salt in the mix is ...

0.80x +0.55(130 -x) = 0.75·130

0.25x = 0.20·130 . . . . . . . subtract 0.55(130)

x = 0.20/0.25(130) = 104

130-x = 26

She should use 26 ounces of 55% solution and 104 ounces of 80% solution.

In circle O, what is mArc A E?

posledela

Answer:

Option (3). 120° will be the answer.

Step-by-step explanation:

By using the theorem of secants intersecting externally,

Measure of angle formed by two secants, from a point outside the circle is half the difference of the measures of the intercepted arcs.

m∠C = $\frac{1}{2}(m\widehat{AE}-m\widehat{BD})$

36° = $\frac{1}{2}(m\widehat{AE}-48)$

72° = $m\widehat{AE}-48$ °

$m\widehat{AE}$ = 72 + 48

$m\widehat{AE}$ = 120°

Therefore, Option (3) is the answer.
