Answer:

By definition of supplementary angles

Step-by-step explanation:

We have to prove that

$\angle 1=\angle 3$

We have to find missing justification in the given proof.

Proof:

Segment CD intersect segment AB

Reason: Given

$\angle 1+\angle 2=180^{\circ}$

$\angle 2+\angle 3=180^{\circ}$

Reason: By definition of supplementary angles

$\angle 1+\angle 2=\angle 2+\angle 3$

Reason: Transitive property

$\angle 1=\angle 3$

Reason: subtraction property of equality

Find the length of the third side. If necessary, round to the nearest tenth.

NikAS [45]

Use the Pythagorean theorem

Side = sqrt(8^2 - 6^2)

Side = sqrt(64-36)

Side = sqrt(28)

Side = 5.29

Rounded to nearest tenth = 5.3

Answer:

$\Large\boxed{21}$

Step-by-step explanation:

To solve this problem, first you have to use the order of operations stands for parenthesis, exponents, multiply, divide, add, and subtract from left to right. Remember to use the order of operations stands for "Please Excuse My Dear Aunt Sally."

Do parenthesis first.

$\displaystyle(8-6)=2$

$\displaystyle 5+4\times2^2$

Next, exponent.

$\displaystyle 2^2=2\times2=4$

$\displaystyle 5+4\times4$

Multiply & divide numbers from left to right.

$\displaystyle 4\times4=16$

Finally, add & subtract numbers from left to right.

$\displaystyle 5+16=21$

As a result, the correct answer is 21.

1. What is the radius<br> (1 Point)<br> 11 cm

mr_godi [17]

Given that we need to determine the radius of the circle.

<u>Radius:</u>

By definition of radius of circle, the radius is the length of the line which is drawn from the center of the circle to any point on the circle.

From the figure, we need to determine the radius of the circle.

As, we can see that, the distance from the center of the circle to the point on the circle is 11 cm.

Since, we know that, the radius is the distance from the center of the circle to the point on the circle then, the radius of the given circle is 11 cm

Thus, radius of the circle is 11 cm.

Ripley’s Aquarium charges $29.95 for (a) adults and $13.95 for (c) children. Write an expression to represent admission pricing

PIT_PIT [208]

Answer:

T=29.95a + 13.95c

Step-by-step explanation:

For this equation let a=amount of adult tickets, c=amount of children tickets, and T=the total cost. Since each adult ticket costs 29.95 dollars that needs to be multiplied by the number of adult tickets to see how much was spent on adults, the same goes for the price and number of children tickets. Finally, both of those totals need to be added together to see how much is spent overall for all of the guests.
