Answers
a. f(a) =5a+12
we have 1. a=6
Therefore, where ever we find a we'll substitute in 6
f(6) =5(6) +12
6f=30+12
6f=42
so therefore 1. a=6 will match c on the right
2. a=2
f(2) =5(2) +12
2f = 10+12
2f = 22
therefore 2. a=2 will match a on the right
3. a=4
f(4) =5(4) +12
4f=20+12
4f=32
therefore 3. a=4 will match d on the right
4. a=5
f(5) =5(5) +12
5f=25+12
5f=37
therefore 4. a=5 will match b on the right

There are 52 cards in a standard deck: 13 hearts, 13 clubs, 13 diamonds , and 13 spades. Timothy draws four cards at random from the deck, one of each suit. If he draws again , without replacing the four he drew, what is the probability that the next card is a heart
Answers
Answer:
[tex]\dfrac{1}{4}[/tex]
Step-by-step explanation:
Total number of cards in a standard deck = 52
Number of hearts in the deck = 13
Number of clubs in the deck = 13
Number of diamonds in the deck = 13
Number of spades in the deck = 13
Four cards are drawn at random by Timothy.
These four cards are drawn from each one of the suits.
And the cards are not replaced.
Therefore, now cards remaining in each suit:
Remaining number of hearts in the deck = 12
Remaining number of clubs in the deck = 12
Remaining number of diamonds in the deck = 12
Remaining number of spades in the deck = 12
Formula for probability of an event E can be observed as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
Here, number of favorable cases are 12 (i.e. number of hearts)
Total number of cases = 12 [tex]\times[/tex] 4 = 48
Therefore, the required probability is:
[tex]\dfrac{12}{48} = \bold{\dfrac{1}4}[/tex]

The payment to a clown for a children's party is directly proportional to the number of
children under 12 at the birthday party. The clown earns $140 at a party that has 10 children attending,
.
How much will the clown earn when 22 children under the age of 12 attend?
If the clown uses 46% of the money earned on his props for the party, and the rest is
profit. What is the profit if only 10 children under the age of 12 attend the party?
Answers
Answer:
Step-by-step explanation:
We know he earns $14 per child under 12
So he'll earn 22 times 14 which is $308 earned.
46% of 308 is basically 0.46 X 308=$141.68 spent on props.
He profits $166.32
If only 10 children attend.
He earns 10 times 14= $140
46% of these earnings is for props and 54% is profit so
0.54 X 140=$75.60.
Thus he profits $75.60 if 10 children attended.
The profit will amount to $75.60 when only 10 children under the age of 12 attend the party.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
We are aware that he receives $14 for each child under the age of 12.
Thus, he will make $308 after multiplying 22 by 14.
In other words, 46% of 308 is 0.46 × 308 or $141.68 spent on props.
He earns $166.32.
If just 10 kids show up.
He makes $10 multiplied by 14 for a total of $140.
Props account for 46% of these revenues, while profits make up 54%, therefore
0.54 × 140=$75.60.
So, if 10 kids showed up, he makes $75.60.
Thus, the profit will amount to $75.60 when only 10 children under the age of 12 attend the party.

Lorena's bank will loan money to customers if they overdraw their accounts by less than 100$. (To overdraw an account means to have the account balance fall below zero.) Lorena started out with a balance of $13.00 and made a withdrawal from her account of $81.50.
Answers
Answer:
a. POSITIVE NUMBER mean availability of money
NEGATIVE NUMBER mean Overdrawn
ZERO mean unavailability of money
b. YES
Step-by-step explanation:
a. Based on the information given the POSITIVE NUMBER mean the AVAILABILITY of some amount of money
A NEGATIVE NUMBER on the other hand mean OVERDRAWN which means that the customer account balance fall below Zero amount
ZERO mean UNAVAILABILITY OF MONEY
b. YES. Based on the information given if Lorena's final account balance has the amount of -$68.50 the bank will loan her reason been that we were told that the bank will give loan to their customers if they overdraw their accounts by less than the amount of $100 in which case Lorena's final account balance has the amount of -$68.50 which is less than $100. Hence the bank will loan her .

What is m ZABC?
c=67 d=60
mABC = 60°
mABC = 67 °
mABC = 120°
mABC = 127°
Answers
Answer:
m∠ABC = 127°Step-by-step explanation:
From triangle BCD:
m∠BCD + m∠CDB + m∠DBC = 180°
67° + 60° + m∠DBC = 180°
m∠DBC = 180° - 127°
An angle ABD is straight angle, so:
m∠ABC + m∠DBC = 180°
m∠ABC + 180° - 127° = 180°
m∠ABC = 127°

A. 4%
B. 96%
C. 177%
D. 7%
Answers
Answer:
B. 96%
Step-by-step explanation:
Sara only missed 7 days of 184 days this year meaning 184 - 7 = 177 and
177 is how many days she attended school, so to figure out percentage take the number of days she attended school and divide by the total amount of days in this year which is 184: 177/184 = 0.96195652173
then multiply by 100 to get percentage so approximately 96%.

Cora ran 3 miles last week and will run 7 miles per week from now on. Hana ran 9 miles last week and will run 4 miles per week from now on.
In the answer box,
Write a system of equations to describe this scenario. Identify what the variables mean in the context of the problem.
Answers
Answer:
If Cora runs 1/2 mile per week and x is the number of weeks, then she will run 5+1/2x. Then determine how many weeks are in two and a half months (depends on which month it is as there are less weeks in February than in January!) but we could estimate 6.
For Hana, you will have 3+ 3/4 x
Step-by-step explanation:
First equation is y=5+1/2 x and then plug 6 in for x to solve for y. the second equation is y=3+3/4x and plug in 6.
The system of equations to describe this scenario are
y = 3 + 7xy = 9 + 4xThe variable x means the number of weeks they ran and the y variable means the total distance they covered in miles .
The situation can be modelled like a linear equation.
Therefore,
y = mx + b
where
m = slope
b = y-intercept
Cora race will be as follows:
y = 3 + 7xHana race will be as follows:
y = 9 + 4xThe variable x which is the independent variable is the number of weeks each of them ran in the equation.
The variable y which is the dependent variable is the total distance covered in miles.

Step-by-step explanation:
County A: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!
$75 * 0.0725 = $5.4375
Add the original price and the sales tax.
$75 + $5.4375 = $80.4375
County B: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!
$70 * 0.08 = $5.6
Add the original price and the sales tax.
$70 + $5.6 = $75.6
Then take the difference.
80.4375 – 75.6 = 4.8375
Round to the nearest hundredth: $4.84
