Amount of Interest:
Total amount paid back:
(Please include how you got the answer and not just take my points for no reason)
Answer:
$5,175
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 4500 × 0.05 × 3 = 675
I = $ 675.00
The simple interest accumulated
on a principal of $ 4,500.00
at a rate of 5% per year
for 3 years is $ 675.00.

Answer:9 /12 -4/12 = 5/12
Step-by-step explanation: First you need to find the same demointaor which can be 12 .You take 3/4 and times on boths side by 3 which gives you 9/12 .You take 1/3 and times on both sides by 4 which gives you 4/12. Now put 9 /12 and then put 4/12 and then subtract both which gives you 5/12.

What is the measure of the missing angle?
280
1200
Answer:
32°Step-by-step explanation:
to understand the solving stepsyou need to know about:triangle contains 180°acute trianglesPEMDASequationgivenangles:28°,120°
to find:missing angle
let's solve:let missing angle be x
as we know
a triangle contains 180° (always)
so,
according to the question
x+28°+120°=180°
x+148°=180°
x=180°-148°
x=32°
Two types of tickets are sold to a play. Floor
seats cost $45 each and balcony seats cost $25
each. A play sells 107 tickets and makes a total
of $3,375. How many of each type of ticket
Answer:
35 tickets at $35, 72 tickets at $25
Step-by-step explanation:
x+y=107 -> 5x+5y=535
45x+25y=3375
simplify, divide by 5 to get
9x+5y=675
Substract
9x+5y=675
- 5x+5y=535
4x=140 -> x=35
y=107-35 = 72

Answer:
one jumbo cost $4 and one chocolate cost $2
Step-by-step explanation:
Let the price eif one jumbo be x
Let the price of one chocolate be y
If one jumbo and 2 chocolate cost$6, then
x+2y= 6 ... 1
If one jumbo and 4chocolate cost $8, then;
x +4y = 8... 2
Subtract both equations
2y -4y = 6-8
-2y= -2
y = 1
Substitute y = 1 into 1;
From 1, x+2y = 6
x +2(1) = 6
x = 6-2
x = 4
Hence one jumbo cost $4 and one chocolate cost $2
Studying atoms helps people by providing research to common problems found in our environment, universe, and ourselves. Such as cleaning up oil spills, identification of atoms in our universe, etc.
Answer:
Many accounts of the atom begin with a history of the growth in scientists' understanding of its structure, but here we will take the opposite approach, first discussing the atom in terms of what physicists and chemists today understand. Only then will we examine the many challenges scientists faced in developing the current atomic model: false starts, wrong theories, right roads not taken, incomplete models. In addition, we will explore the many insights added along the way as, piece by piece, the evidence concerning atomic behavior began to accumulate. People who are not scientifically trained tend to associate studies of the atom with physics, not chemistry. While it is true that physicists study atomic structure, and that much of what scientists know today about atoms comes from the work of physicists, atomic studies are even more integral to chemistry than to physics. At heart, chemistry is about the interaction of different atomic and molecular structures: their properties, their reactions, and the ways in which they bond.
Step-by-step explanation:
Sample Response: "Studying atoms is important because knowledge about atoms helps people to understand the world around them and produce materials used in daily life. Also, research done on atoms has contributed to the improvement of people's lives through medicine, to the protection of the environment, and to the discovery of new things about the world and the universe."
Find the product.
−3y2 (−4y3 + y − 9)
The product of the expressions is 12y⁵-3y³+27y²
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given that, two expressions, -3y² and (-4y³+y-9) we need to find their products,
So,
= -3y² x (-4y³+y-9)
= -3y²(-4y³) -3y²(y) -3y²(-9)
= 12y⁵-3y³+27y²
Hence, the product of the expressions is 12y⁵-3y³+27y²

is there one solution, no solution or infinite solutions for 7x+14=7(x+2)
Answer:
infinite solutions
Step-by-step explanation:
Answer:
Infinite Solutions
Step-by-step explanation:
To solve for the solution, distribute the 7 into (x+2), and the result is:
7x+14=7x+14
This means that the solution can be all values of x
For example, when x=1,
7(1)+14=7(1)+14
21=21
When x=2,
7(2)+14=7(2)+14
28=28

Step-by-step explanation:
Step(i):-
Given that the size of the sample 'n' =200
Given that the sample proportion
p = 45% = 0.45
Level of significance = 90% or 10%

Answer:
- 9Step-by-step explanation:
3 cos π - 12 sin (5π/6) = 3(-1) - 12 sin (π - π/6) = -3 - 12 sin π/6 = -3 - 12(1/2) = -3 - 6 = -9Use the terms 4, 12a 6 2a and 24 to make equivalent expressions use each term only once use substitution to prove that the expressions are equivalent
Answer:
12a + 24 = 6(2a + 4)
Step-by-step explanation:
Given the numbers :
4, 12a 6 2a and 24 ; create an equivalent expression :
12a, 2a, 4, 6, 24
We could separate tbe constant terms and those with variables :
12a, 2a ; 6, 4, 24
We could put the larger digit to one side
12a + 24 = 6(2a + 4)
This way the Right hand side is equal to the left hand side.
Check:
12a + 24 = 6(2a + 4)
12a + 24 = 12a + 24
Hence, the proof
