Answer: oh boi this is gonna take a long time to type. hang in there.

Step-by-step explanation:

#1: Soooooo. A rule is used to find the age of Cassandra's mother no matter the age of Cassandra. Therefore, the answer to #1 is 2C + 9 = M where C is equal to the age of Cassandra.

#2: The rule 2C + 9 = M relates to this because the variale C represents Cassandra's age, the +9 represents her age plus nine is her Mother's age, the 2 in front of the variable C represents the doubling of Cassandra's age, and M represents her mother's age.

#3: The rule IS the process that each student used to find her mother's age. This is how they are both related (the process and the rule).

#4: This is all you because I'm pretty sure this is from another problem you did or something.

#5: For a and b, try to find what x (the input) is done to ... to get y (the output). Look for patterns between the two numbers and look for a RULE that can be used for all. The number 0 is the most important when looking for the rule. :)

OH! MAKE SURE TO PUT THIS INTO YOUR OWN WORDS! (maybe you and i have a different way of speaking and this might get SUS)

Karo-lina-s [1.5K]

The statements that are true are:

A : Vertical angles are congruent, therefore, another angle must equal 67°

F: Two of the angles formed will have a sum of 180°

What happens when two lines intersect?

When two lines intersect, their vertical angles are always the same and the sum of the two angles on a straight line is 180°

Abby scored 87, 86, 93, and 89 on her first four history quizzes. What score does Abby need to get on her fifth quiz to have an

Delicious77 [7]

Answer:

Step-by-step explanation:

The average of a data set is just all the numbers added up divided by the amount of numbers.

If we already have 4 pieces of data and we're looking for one more, we have 5 data pieces.

This means that the sum of all of the numbers in the data set will be $91\cdot5=455$ if the mean is 91.

We can find the missing value by adding up what we know and subtracting from 455.

$87+86+93+89=355\\\\455-355=100$

So Abby needs a 100% on her fifth history quiz to have an average of 91 on all her quizzes.

Hope this helped!

Artist 52 [7]

Answer:

$478.80

Step-by-step explanation:

We have been given that 15 players two coaches and 21 parents attend this year sports banquet the cost of each meal was $12 plus 5% sales tax.

First of all, we will find cost of each meal with tax as:

$\text{Cost of each meal with tax}=\$12+\$12\times \frac{5}{100}$

$\text{Cost of each meal with tax}=\$12+\$12\times 0.05$

$\text{Cost of each meal with tax}=\$12+\$0.6$

$\text{Cost of each meal with tax}=\$12.6$

Now, we will find total persons at the sport banquet as:

$\text{Total persons at banquet}=15+2+21$

$\text{Total persons at banquet}=38$

To find the total cost of food for the banquet, we will multiply cost of food for each person by 38.

$\text{Total cost of food for the banquet}=\$12.6\times 38$

$\text{Total cost of food for the banquet}=\$478.8$

Therefore, the total cost of food for the banquet is $478.80.
