Hiran invests 20 000 rupees in an account for 3 years at 1.5% per year compound interest.
Work out the total amount of money in the account at the end of 3 years.
Give your answer to the nearest rupee.
Answer:
There will be 20 914 rupees in the amount at the end of 3 years.
Step-by-step explanation:
The amount of rupes after t years in compound interest is given by:
[tex]A(t) = A(0)(1+r)^{t}[/tex]
In which A(0) is the initial amount and r is the interest rate, as a decimal.
Hiran invests 20 000 rupees in an account for 3 years at 1.5% per year compound interest.
This means that [tex]A(0) = 20000, r = 0.015[/tex]. So
[tex]A(t) = A(0)(1+r)^{t}[/tex]
[tex]A(t) = 20000(1+0.015)^{t}[/tex]
[tex]A(t) = 20000(1.015)^{t}[/tex]
Work out the total amount of money in the account at the end of 3 years.
This is A(3). So
[tex]A(3) = 20000(1.015)^{3} = 20913.6[/tex]
Rounding to the nearest rupee.
There will be 20 914 rupees in the amount at the end of 3 years.

Make x the subject of the formula 7 + x = t
Answer:
x = t-7Step-by-step explanation:
[tex]7 + x = t[/tex]
Move 7 to the right side.
Note : That when a number crosses an equality sign , the sign changes.
[tex]x = t - 7[/tex]
Answer:
x=t-7
Step-by-step explanation:
To make x the subject of the formula 7 + x = t
What we mean is that we want x to stand alone.
So if we want x to stand alone then we will subtract both sides by 7 to make the x stand alone.
-7+7+x=t-7
x = t - 7
So now the final answer becomes;
x = t - 7

Jill spent 12% of her money on a book. After buying the book, she had $120.12. How much money did Jill have before buying the book?
Answer:
Jill had $136.50 before buying the book.
Step-by-step explanation:
Let x be the total amount that Jill had
Then 12% of x is 0.12x
Jill was left with $120.12 after buying the book
Subtracting the cost of book from the total amount will given us the remaining amount.
Which means
[tex]x - 0.12x = 120.12\\0.88x = 120.12\\x = \frac{120.12}{0.88} \\x = 136.50[/tex]
Hence,
Jill had $136.50 before buying the book.

A blueprint of an apartment is shown below. What is the actual length of the longest wall in the living room in feet? 0.5 inch : 6 feet Living Room Bedroom Bath 1.5 in.
Answer:
36 feet long.
Step-by-step explanation:
If the longest wall in the living room is referring to the side that I have drawn over in white and red in the attached image, or if it is the leftmost wall, then that wall is 36 feet long. For every half inch, it is 6 feet, so because there are 6 'half inches' in 3, you multiply 6 feet by the 6 half inches there are, and get 36. There are simpler ways to solve it but I can't take a picture of my work, so I hope this helps. Good luck.
The actual length of the longest wall in the living room is 36 feet.
The blueprint is a scale drawing of the apartment. A scale drawing is a smaller diagram of a large image. A scale drawing is reduced by constant dimensions.
Looking at the given image, the longest wall is 3 inches.
The length of the longest wall in the apartment : (3 in x 6) / 0.5
=18 / 0.5
= 36 feet

Find the angle of elevation if the building is 653 feet tall and the observer is 150 feet from the building. Round to the nearest tenth of a degree
Answer:
Angle of elevation = 77.1°
Step-by-step explanation:
The formula to solve for angle if elevation is given below as:
tan θ = Opposite/ Adjacent
Where
Opposite = Height of the building = 653 ft
Adjacent = Distance from the building = 150 ft
θ = Angle of Elevation = ?
Hence:
tan θ = 653ft/150ft
θ = arc tan (653ft/150ft)
= 77.063069956°
Approximately to the nearest tenth = 77.1°
Difference(s) between volume and surface area
Answer:
Step-by-step explanation:
Surface area is the sum of the areas of all the faces of the solid figure. Finding surface area of solid figure is like finding how much wrapping paper that is required to cover the solid; it is the area of the outside faces of a box. ... Volume is the amount of space inside of the solid figure.

If a – 2 = -12, then a = ______.
Answer:
a= -10
Step-by-step explanation:
To do this you would need to isolate a, or make a stand alone on its side of the equation
a-2=-12 Original equation
a-2+2 = -12+2 Isolating the variable(adding the 2 will cancel the -2 on the left side of the equation)
a= -12+2 Simplification
a= -10 The answer!!!
I hope this helps!!!

Answer:
d. V = π(x^3 + 90x^2 + 2,400x + 20,000)
Step-by-step explanation:
volume of cylinder = πr^2h
We have r = x + 20; h = x + 50
V = π(x + 20)^2(x + 50)
V = π(x^2 + 40x + 400)(x + 50)
V = π(x^3 + 50x^2 + 40x^2 + 2000x + 400x + 20,000)
V = π(x^3 + 90x^2 + 2,400x + 20,000)

-> 32
The model predicts ... 40 ...
-> The green 8 with an arrow shows the prediction
-> 40 - 8 = 32
-> 40
... 8 below what the model predicted

Answer:
15 + 5x
Step-by-step explanation:
8x + 1 + 7x + 4
All that you need to do is combine like terms which means that you need to put together (either add or subtract) the numbers that are similar...so the numbers with the numbers, and the variables with the variables...
8x + 7x and 1 + 4
15x + 5
And you cannot do anything else because it is in its simplest form.

Ammar hikes 2 3/4 miles of nature trail in 1 hour and 15 minutes. 4
How many miles of trail does Ammar hike per hour?
Answer:
.42 mph
Step-by-step explanation:
The problem tells us theres 2.75/1.15 miles/hour. And we want to know x/1 miles/hour. To do this you cross-multiply using whats been referee to as the butterfly method. So take 2.75*x=1.15*1. Then you simplify and get 2.75x=1.15. To get x along you must divide which leaves you with. X=.4182(rounded). So you can go .42 miles per hour.
