2. For a simple interest rate of 10%, p.a calculate the number of year's needed for an interest of $1149.60 to be earned on an investment of $2874
Answers
Answer:
r=10%
I=1149.60
P=2874
t=(I×100)/(p×r)
(1149.60×100)/(2874×10)
114960÷28740
4 years
[tex]r = 10\%[/tex]
[tex]p = 2874[/tex]
[tex]l = 1149.60[/tex]
to find:the numbers of year's needed for the investment.
solution:[tex]t = \frac{l \times 100}{p \times r} [/tex]
[tex]t = \frac{1149.60 \times 100}{2874 \times 10} [/tex]
[tex]t = \frac{114960}{28740} [/tex]
[tex]t = 4[/tex]
therefore, 4 years is needed for the investment.

Answer: Given that MP \\NS , RS\\PQ and MR =NQ
MRN is a straight line with sum of angles equal to 180⁰ MQN is also a straight line triangle equal to 180⁰
Angle at R + 3 = Angle at Q +2 = 180⁰
Angle R is alternate to Q and angle 2 is alternate to 3 and both sets are equal
Therefore angle 1 is equal to 4 and this makes their third angles in the triangle equal.
Triangle MQP then becomes a perfect replica of NRS

While you're in the parking lot, you realize that both the lightbulbs and the light switches
need to be replaced. You buy 9 bulbs and 4 switches. Each light switch cost $8 less than
each lightbulb. If the total cost is $520.50, what is the cost of one lightbulb? What is the cost
of one light switch? Write an equation for the situation.
Let x = the cost of a lightbulb
Answers
Cost of Lightbulb = x
cost of switch is x-8
9x + 4(x-8) = 520.50
Use distributive property:
9x + 4x -32 = 520.50
Simplify:
13x -32 = 520.50
Add 32 to both sides:
13x = 552.50
Divide both sides by 13
X = 42.50
A lightbulb costs $42.50
A switch costs 42.50-8 = $34.50

Principal: $1,000
APR: 4.5%
Time: 10 years
Find the equations for annually, quarterly, monthly and daily
Answers
Answer:
see attached
Step-by-step explanation:
You are asked to use the compound interest formula for different values of n, the number of times per year the interest is compounded.
__
The basic formula is ...
A = P(1 +r/n)^(nt)
for the amount in an account in which principal P earns interest at annual rate r compounded n times per year for t years.
The problem statement gives values for P, r, t, so we only need to compute the result for different values of n. With the given values filled in, the formula is ...
A = 1000(1 +0.045/n)^(10n)
Values of n to be used are ...
annually: n = 1quarterly: n = 4monthly: n = 12daily: n = 365The formula you will evaluate uses these values where 'n' is in the formula. Corresponding account balances are ...
annual compounding: $1552.97quarterly compounding: $1564.38monthly compounding: $1566.99daily compounding: 1568.27__
For repetitive evaluation of the same formula, we like a calculator or spreadsheet. Many calculators have the "time value of money" formulas pre-programmed. This is shown in the second attachment, where the value that varies is "C/Y", the number of compoundings per year.
why do we need math and history
Answers
Answer: Math and history are very important!
Step-by-step explanation: We use math every day, some people more than others. Math helps your brain become more smarter. It gives us a way to understand different types of patterns better, to quantify relationships, and to in some cases, predict the future. There are many reasons that math is important to us, but what about history? History gives us a tool to help us better understand our past, helping us to spot patterns that are invisible in the present. We can learn about past societies, past ideologies, and lots of other things to see how we got to where we are now. Studying math and history might be boring, pointless, or hard right now(I struggle with math!), but these two subjects are used in everyday life!
There are a number of reasons why studying history and mathematics is crucial. Although history aids in the knowledge of the past, the development of critical thinking abilities, and the development of cultural understanding, mathematics gives a framework for comprehending the world around us and develops essential skills.
What is the importance of math in real life?A person who is proficient in maths can manage a budget, construct furniture, predict, and tell time, among other essential life abilities. As an adult, you need to be able to analyse expenditures, balance a chequebook, and deduct balances. Math can help you with these tasks. Math helps you become a better cook.
Several everyday uses of mathematics exist in contemporary life. It offers a common vocabulary for speaking about and comprehending the physical world. Engineering, computer science, physics, finance, and many other professions depend heavily on mathematics. Many of the technical advancements we take for granted today, like cell phones and space travel, would not exist without mathematics.
On the other hand, history is the study of historical occurrences and their importance. It is significant for a variety of reasons, such as:
History may teach us important lessons that will help us in the future. We may learn how to prevent or repeat prior errors and accomplishments by looking at what went right and wrong in the past.Understanding the current: History enables us to understand how current events continue to be shaped by earlier ones and how they have impacted our world.Understanding diverse civilizations: History offers a glimpse into many cultures and communities.Therefore, both mathematics and history are significant academic disciplines for a variety of reasons. Although history enables us to comprehend the past, learn from it, and foster cross-cultural understanding, mathematics gives us a framework for understanding the world around us and develops crucial abilities.

had both a pet dog and a pet cat.
What is the probability that a randomly chosen student at Michael's school will have a pet dog or a pet cat?
A. 62%
B. 51%
C. 40%
D. 83%
Answers
11% of the students have a pet dog AND a pet cat. Because of this you want to take away 11% from the percentage of students with a pet dog and also from the percentage with a pet cat. This is because 11% of the students with a pet dog also have a pet cat and vice-versa and you don’t want to count any students twice.
Once you’ve done this it’s very simple, just add up your values, so 11 + (38 - 11) + (24 - 11) which will give you 51.

We'll use p as a variable for the total players, alright?
So, 25% of p usually gets called back.
This season, 17 is 25% of p OR you might say 17 = 1/4 of p
in other words, p/4 = 17
multiply each side by 4 (to get the variable alone)
p = 17 * 4
p = 68

2. A line with slope passes through the point (1,3
a. Explain why (3, 6) is on this line.
b. Explain why (0, 0) is not on this line.
Answers
Answer:
Step-by-step explanation:
If a line with a slope passes through a point with a value such as in this one, which is (1,3), then it must have a y-intercept and a slope. The y-intercept is when the x-value's value is 0 but the y-value is more than 0.
(3,6) is on the line as it corresponds with the slope.
(0,0) is not on this line as the y-value nor the x-value has a coordinate, which is a requirement to make it an ordered pair.

4m +3m -5 +3= 180
