Answer:

\text{1. }50^{\circ}\\\text{2. }80^{\circ}

Step-by-step explanation:

1. The measure of an inscribed angle is always half the measure of the arc it forms. Since angle ACB forms arc AB with a measure of 100 degrees, the measure of angle ACB will be equal to \frac{100}{2}=\boxed{50^{\circ}}.

2. Relating to problem 1, both inscribed angles marked in the figure form the same arc. All inscribed angles forming the same arc will have the same measure. Therefore, the measure of angle GEF is equal to \boxed{80^{\circ}}.

Serggg [28]

Answer:

B. x<27

Step-by-step explanation:

The shelter has 165 animals.

The shelter must keep its total occupancy below 300.

The shelter takes in an average of 5 animals per day. If x is the number of days, then in x days the shelter takes 5x animals. In total there will be

165+5x animals. This number must be less  than 300, so

165+5x< 300\\ \\5x< 300-165\\ \\5x< 135\\ \\x< 27

Correct answer is option D.

The solution is listed below

F(x)=4x+7 \\  \\ &#10;y=4x+7 \\  \\ &#10;y-7=4x \\  \\ &#10; \frac{y-7}{4}=x \\  \\ &#10; x= \frac{y-7}{4} \\  \\ &#10;f-^{1}(y) = \frac{y-7}{4} \\  \\ &#10;f-^{1}(x) = \frac{x-7}{4} \\  \\ &#10;
