Liz spent her summer break working at Wild Lakes waterpark. At the end of the summer, she put $570 of her earnings into a savings account that earns 1% interest each year.
The total simple interest earned by Liz at the end of 5 years is found as: $28.5
Explain about the simple interest?A straightforward but effective idea. Very simply: interest is the benefit for saving - and the penalty of borrowing.
When you deposit funds into a savings account, you are paid interest, or additional money on top. The reason for this is that the bank gives you interest for letting them use your money.When someone owes money, they are assessed this fee. It indicates the time worth of money and is charged in relation to the principal sum. It is the prize for holding out and refusing to accept an early reward.Principal P = $570
Interest r = 1%
Time t = 5 years.
SI = P*R*t / 100
SI = 570*1*5 / 100
SI = 28.5
Thus, the total simple interest earned by Liz at the end of 5 years is found as: $28.5.

Describe Function?A function can be represented in several ways, including using algebraic expressions, tables, graphs, or even words. For example, the function f(x) = 2x + 1 defines a relationship between the input x and the output 2x + 1. If we input x = 3 into this function, the output would be f(3) = 2(3) + 1 = 7.
Functions can have different properties, such as being continuous or discontinuous, being differentiable or nondifferentiable, or having maximum or minimum values. Functions can also be classified according to their types, such as linear, quadratic, exponential, logarithmic, trigonometric, or piecewise-defined functions.
Functions are used extensively in mathematics, science, engineering, economics, and many other fields to describe real-world phenomena and to solve practical problems.

Martha likes to knit hats and mittens for friends and family. Last fall, she knitted 3 hats and 3
pairs of mittens, which took a total of 51 hours. This fall, she knitted 3 hats and 5 pairs of
mittens, which took a total of 77 hours. If each hat takes the same amount of time and each
pair of mittens takes the same time, how long does it take Martha to knit each item?
hours to knit a pair of mittens.
It takes Martha
hours to knit a hat and
It takes Martha `4` hours to knit each hat and `13` hours to knit each pair of mittens.
What is meant by hours?
Hours are a unit of time used to measure the duration of an event or activity. An hour is equal to 60 minutes or 3,600 seconds. It is often used to indicate the time of day or to schedule appointments or events.
What is a pair?
A pair is a set of two things that go together or belong together, like a pair of shoes, socks, or gloves. It can also refer to a pair, a duo, or a twosome.
According to the given question
Let's assume that each hat takes `h` hours to knit and each pair of mittens takes `m` hours to knit.
From the given information, we know that:
- 3 hats and 3 pairs of mittens took a total of 51 hours. This means that 3h + 3m = 51.
- 3 hats and 5 pairs of mittens took a total of 77 hours. This means that 3h + 5m = 77.
We can use these two equations to solve for `h` and `m`.
First, let's solve for `h` by multiplying the first equation by 5 and the second equation by 3, and then subtracting the second equation from the first:
15h + 15m = 255
9h + 15m = 231
-----------------
6h = 24
h = 4
So each hat takes Martha `4` hours to knit.
Now we can use either of the original equations to solve for `m`. Let's use the first one:
3h + 3m = 51
3(4) + 3m = 51
12 + 3m = 51
3m = 39
m = 13
So each pair of mittens takes Martha `13` hours to knit.

The cooler at a picnic contained 4 apple juice boxes, 8 orange juice boxes, and 6 fruit punch juice boxes. a juice box is selected at random. what is the probability of the complement of choosing an orange juice box?
a. startfraction 1 over 18 endfraction
b. startfraction 4 over 9 endfraction
c. startfraction 5 over 9 endfraction
d. startfraction 17 over 18 endfraction
The probability of the complement of choosing an orange juice box is 17/18. (option d)
The complement of an event is the probability of that event not occurring. In this case, the event is choosing an orange juice box, so the complement is choosing any other juice box (i.e., an apple juice box or a fruit punch juice box).
The total number of juice boxes in the cooler is:
4 + 8 + 6 = 18
The number of juice boxes that are not orange juice boxes is:
4 + 6 = 10
Therefore, the probability of choosing a juice box that is not an orange juice box (i.e., the complement of choosing an orange juice box) is:
10/18 = 5/9
But the question asks for the probability of the complement, which is the probability of not choosing a juice box that is not an orange juice box. This is simply:
1 - 5/9 = 4/9
However, the question asks for the probability of the complement of choosing an orange juice box, not the complement of not choosing an orange juice box. These two probabilities are equal, since the event and its complement always add up to 1. Therefore, the probability of the complement of choosing an orange juice box is:
1 - 8/18 = 10/18 = 17/18
Therefore, the probability of the complement of choosing an orange juice box is 17/18.

I have 1,792 Pokémon cards, I also have 7 friends. I want to split the cards between me and the 7 of them. How many cards should each person get? Does the answer of this question has a remainder? Solve and Explain how you got your answer
We can confirm that each person should receive exactly 224 Pokémon cards, and there won't be any cards left over.
To split the 1,792 Pokémon cards equally between 8 people, including yourself and your 7 friends, you need to divide the total number of cards by the number of people:
1,792 cards ÷ 8 people = 224 cards per person.
So each person should get 224 Pokémon cards.
However, we should also check if there is a remainder after the division. To do that, we can multiply the number of cards each person is getting by the number of people and subtract it from the total number of cards:
224 cards/person x 8 people = 1,792 cards
1,792 cards - 1,792 cards = 0 remainder
Since there is no remainder, we can confirm that each person should receive exactly 224 Pokémon cards, and there won't be any cards left over.

If P represents the number of pounds of your package, and C is the total cost of shipping your package, write an equation that represents the relationship between P and C
If P represents the number of pounds of your package, and C is the total cost of shipping your package, the equation that represents the relationship between P and C is C = 3 + 0.63P.
To write an equation that represents the relationship between the weight of the package (P) and the total cost of shipping (C), we need to use the information given in the problem. The shipping company charges a fixed base cost of $3 per package plus an additional $0.63 per pound.
We can represent the additional cost per pound as 0.63P, since the cost increases by $0.63 for every additional pound. Therefore, the equation that represents the relationship between P and C is:
C = 3 + 0.63P
This equation gives us the total cost of shipping a package based on its weight. We can use this equation to calculate the cost of shipping a package of any weight by simply plugging in the weight (in pounds) for P and then solving for C.
For example, if a package weighs 5 pounds, we can substitute P = 5 into the equation to get:
C = 3 + 0.63(5)
C = 3 + 3.15

to help you answer the next question. *
Yes, they will reach their goal of $45.00 by selling 12 cups of lemonade on Sunday.
Yes, they will reach their goal. To calculate this we can use the following formula:
Total Sales = (Number of cups sold on Saturday × Price per cup) + (Number of cups sold on Sunday × Price per cup)
Total Sales = (37 × 0.75) + (12 × 0.75)
Total Sales = 27.75 + 9
Total Sales = 36.75
Since 36.75 is greater than the goal of 45.00, they will reach their goal. This can be further verified by looking at the total cost of the cups they sold. 37 cups sold on Saturday at $0.75 each will cost $27.75. Adding the 12 cups sold on Sunday at $0.75 each will cost $9, bringing the total cost of the cups sold to $36.75. This is the same amount that was calculated using the formula above. Therefore, they will reach their goal by selling 12 cups of lemonade on Sunday.

Given the following question:
We have 60 balloons in total
4/12 of the balloons are black
3/12 of the balloons are white
We are trying to find the amount of red balloons Carter has:
Let...
B = black
W = white
R = red
[tex]B=(\dfrac{4}{12}) \times60=20[/tex]
[tex]B=20[/tex]
[tex]W=(\dfrac{3}{12}) \times60=15[/tex]
[tex]20+15=35[/tex]
[tex]60-35=25[/tex]
[tex]R=25[/tex]
Carter has 25 red balloons
