Poison Ivy received a total piecework paycheck of $465.47. She receives 89 cents per unit produced. How many units did she produce?
There are 523 units did she produced.
What is paycheck?
Traditionally, an employer would issue a paper document known as a paycheck—also spelled pay cheque, pay check, or pay cheque—to pay an employee for services rendered.
Businesses pay their employees for their work through paychecks. Bi-weekly and semi-monthly delivery schedules are the most typical ones, though this can change depending on the employer's preferences and any applicable state laws and regulations.
Given that:
Piecework pay = $465.47
Price per unit = 89 cents = $0.89
Number of units=$x
Let,
Total piecework pay = Price per unit x number of items sold
$465.47 = 0.89 x x
x = 523
Hence, there are 523 units did she produced.

A worker will waterproof 4 commercial roofs if he spends 1 1/4 of waterproofing for each roof.
How many liters does he need to do the job?
If you already had 2 1/4 liters, then how much waterproofing do you need?
is fractions with procedure
-First question:
To calculate the number of liters, the number of roofs must be multiplied by the amount of waterproofing used for each roof.
To multiply the fractions, transform the mixed fractions to improper:
[tex]\begin{gathered} \sf1 \frac{1}{4} \times 4 = \\ \\ \sf \frac{4 \times 1 + 1}{4} \times \frac{4}{1} = \\ \\ \sf \frac{4 + 1}{4} \times \frac{4}{1} = \\ \\ \sf\frac{5}{4} \times \frac{4}{1} = \\ \\ \sf \frac {5 \times 4}{4 \times 1} = \\ \\ \boxed{ \sf \frac{ \red{20}}{ \red4}} = \sf \blue5\end{gathered}[/tex]
So you need five liters of waterproofing to get the job done.
-Second question:
To calculate the number of liters; It must be subtracted from the number of liters you need in total, which you already had or had:
[tex]\begin{gathered} \sf5 - 2 \frac{1}{4} = \\ \\ \sf \frac{5}{1} - \frac{4 \times 2 + 1}{4} = \\ \\ \sf\frac {5}{1} - \frac{8 + 1}{4} = \\ \\ \sf \frac{5}{1} - \frac{9}{4} = \\ \\ \sf\frac{4 \div 1 \times 5 - 4 \div 4 \times 9}{4} = \\ \\ \sf \frac{20 - 9}{4} = \\ \\ \boxed{ \sf \frac{11}{4}} = \boxed{ \sf \blue2 \: \: \blue{\sf\frac{3 }{4} }}\end{gathered}[/tex]
So, you need two whole and three quarter liters of waterproofing.

2. Table 1 shows the number of pupils attending a motivation camp.
Two pupils from the group are required to take part in a show.
a) If a pupil is chosen at random from school A and another one from school B, calculate the probability that both are girls.
b) If two pupils are chosen at random from the group of boys, calculate the probability that both are from the same school.
a) The probability that both are girls is of: 21/150.
b) The probability that both are from the same school is of: 0.7333 = 73.33%.
How to obtain the probabilities?The probabilities are obtained as the division of the number of desired outcomes by the number of total outcomes.
For item a, the outcomes are given as follows:
One girl from school A -> 7/15 probability.One girl from school B -> 3/10 probability.Hence the probability that both are girls is of:
p = 7/15 x 3/10 = 21/150.
The probability that the two boys are from the same school can be given by these two cases:
School A: 8/15 x 7/14.School B: 7/10 x 6/9.Then the probability is of:
p = 8/15 x 7/14 + 7/10 x 6/9 = 0.7333 = 73.33%.

For the following word problems, first write a system of equations then solve for full marks.
3. The perimeter of a rectangle is 64 cm. Twice the width is 4 cm more than the length.
Find the dimensions of the rectangle.
The length of rectangle is 20cm and width is 12cm.
Let the length is x cm and width is y cm.
then perimeter 2(x+y) =64 cm
=> x+y = 64/2 = 32
=> x + y = 32 .............(1)
and according to question twice the width is 4cm more than length so,
2y = x + 4
=> 2y -x = 4 .............(2)
now we add these two equation to find the value of x and y.
3y = 36
=> y = 12
now put the value of y on any equation to find value of x ,
x +12 = 32
=> x = 32 -12 = 20

Tami rolled a die 20 times. 14 times it landed on an even number; 6 times it landed on an odd number. How does the experimental and theoretical probability compare, for rolling an odd number?
A)
The theoretical probability is higher.
B)
The experimental probability is higher.
C)
The experimental and theoretical probability are equal.
The answer is the Theoretical probability is higher than the Experimental probability.
Experimental and Theoretical Probabilities:Experimental probability:
The basis for experimental probability is what actually happens. It is dependent on the outcomes of several tests or experiments.
It is calculated by repeatedly recreating the event, recording the outcomes, and then converting the outcomes into a ratio or decimals.
Experimental probability = No of times event occurs/ No of trials
Theoretical Probability:
Theoretical probability is derived from a theory or what is predicted to occur. It is based on information and math.
It is determined by dividing the total number of outcomes by the proportion of favorable results. Either convert it to decimal form or leave it as a ratio or fraction.
Theoretical probability = No of favorable outcomes/ No of outcomes
Here we have
Tami rolled a die 20 times
14 times it landed on an even number;
6 times it landed on an odd number.
The die rolled for an odd number
As we a die will have 6 faces
Number of odd numbers = 3 [i.e 1, 3, 5 ]
Number of even numbers = 3 [ i.e 2, 4, 6 ]
⇒ Theoretical probability = 3/ 6 × 100 = 50%
The die is rolled 20 times, 6 times it landed on an odd number.
⇒ Experimental probability = 6 / 20 = 30%
As we can see,
The theoretical probability is higher than the Experimental probability.
Therefore,
The answer is the Theoretical probability is higher than the Experimental probability.

7 people equally share 1/2 a pan of macaroni and cheese how much of the whole pan each person get
Answer:
1/14
Step-by-step explanation:
If 7 people equally share 1/2 a pan of macaroni and cheese, each person will get 1/2 / 7 = 1/14 of the pan.
To find the fraction of the pan that each person gets in terms of the whole pan, we can multiply the fraction 1/14 by the denominator of the fraction representing the whole pan. If the whole pan is represented by 1 pan, the fraction representing each person's share would be 1/14 * 1 = 1/14 of a pan.
So, each person would get 1/14 of a pan of macaroni and cheese.

The probability that the card is between four and eight (inclusive) or is a club is 4/13.
What is Probability?Probability helps us to know the chances of an event occurring.
The number of cards can be written as,
The number of cards between 4 and 8 is 3 {4,5,6,7,8}.
Number of club cards = 13
Number of cards between 4 and 8 from heart, spades, and diamonds = 15
Now, the probability that the card is between four and eight (inclusive) or is a club is,
Probability = desired outcomes / total number of outcomes possible
= (Number of club cards+ Number of cards between 4 and 8)/(Total number of cards)
= (13+15)/(52)
= 28/52
= 4/13

A is a right triangle's side.
B is the right triangle's side.
c = hypotenuse
Think of a right triangle where the height and distance are the legs and the hypotenuse is the rope.
We are aware that:
cos(45°) =x/10
cos(30°) =y/10,
where x represents the distance between the ship and the dock at low tides and y represents the distance during high tides.
We are searching for the y-x distance difference (since it will be farther away during high tides).
Using the previous equations:
x=cos(45°) and y=cos(30°)
Hence:
y - x = 10(cos(30°) - cos(45°))
Hence, the exact value of the distance is 10(cos30° - cos45°)
