Deidre goes out for lunch and realizes that she only has $10 with her. If she wants to leave a 20% tip and knows she will have to pay 5% tax on her lunch, what is the most expensive lunch she can order?
Answer:
$7.60
Step-by-step explanation:
10 decrease 20% =
10 × (1 - 20%) = 10 × (1 - 0.2) = 8
8 decrease 5% =
8 × (1 - 5%) = 8 × (1 - 0.05) = 7.6
A man invests 10000 for 3 years at a certain rate of interest, compounded annually. At the
end of one year, it amounts to 11200. Calculate :
(i) the rate of interest per annum;
(ii) the interest accrued in the second year;
(ii) the amount at the end of the third year.
Step-by-step explanation:
10000, After 1 year amount = 11200 so interest after 1 year = 1200
Amount = P(1+R/100)T
11200 = 10000(1+R/100)1
R = 12%
Interest for the second year = 11200(1+12/100)1 - 11200 = 1344
after 3 years = 10000(1+12/100)3 = 14049.28
Step-by-step explanation:
(I) Principle = Rs 10000, After 1 year amount
= Rs 11200 so interest after 1 year
= Rs 1200
R = 12%
Amount = P(1+R/100)T
11200 = 10000(1+R/100)1
R = 12%——————————————————————————————————————
(Ii)Interest for second year = 11200(1+12/100)1 - 11200 = Rs 1344
(iii)Amount after 3 year = 10000(1+12/100)3 = Rs 14049.28

220 is divided in the ratio 3:8 as 60 and 160 respectively.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
The given ratio is 3:8 and the number is 220.
Here, 3+8=11
Now, 3/11 ×220
= 3×20
= 60
8/11 ×220
= 8×20
= 160
Therefore, 220 is divided in the ratio 3:8 as 60 and 160 respectively.

Read the excerpt from "The Tell-Tale Heart."
Which statement best explains how the reader can
determine that the narrator is unreliable?
But you should have seen me. You should have seen
how wisely I proceeded—with what caution—with what
foresight—with what dissimulation I went to work! I was
never kinder to the old man than during the whole week
before I killed him. And every night, about midnight, I
turned the latch of his door and opened it-oh so
gently! And then, when I had made an opening
sufficient for my head, I put in a dark lantern, all closed,
closed, that no light shone out, and then I thrust in my
head. Oh, you would have laughed to see how
cunningly I thrust it in!
O The narrator is very kind to the old man during the
whole week before the murder.
O The narrator checks on the old man every night at
midnight to ensure his well-being.
O The narrator closes the lantern tightly so the old
man is not awakened by the bright light.
O The narrator believes that his audience will approve
of and even laugh at his plot to murder the old man.
Answer:
The narrator checks the old man at every night at midnight

An electrician bought 120 feet of electrical wire and used 105 feet of it
What percent of the wire went unused?
A 15%
B 12.5%
C 8.75%
D 7%
Answer:
B. 12.5%
Step-by-step explanation:
Find how much was unused:
120 - 105
= 15
To find what percent this is, divide it by 120:
15/120
= 0.125
Multiply this by 100:
0.125(100)
= 12.5
So, 12.5% of the wire went unused
The correct answer is B. 12.5%

An artist builds a sculpture out of metal and wood that weighs 14.4 kilograms. 3/4 of this weight is metal, and the rest is wood. How much does the wood part of the sculpture weigh?
Answer: weight of wood part = 3.6 kilogram.
Step-by-step explanation:
Sculpture made of both metal and wood = 14.4 kilogram
Weight of metal=3/4 of 14.4 kilogram
which means the weight of metal = 3/4 x 14.4kg= 10.8kg
Since the rest is wood, we can say that
weight of wood = Total weight - weight of metal
= 14.4 kilogram- 10.8 kilogram= 3.6 kilogram

Hi! Your answer is x = 3.
Please see an explanation for a clear and better understanding to your problem.
Any questions about my answer and explanation can be asked through comments! :)
Step-by-step explanation:
Our goal is to find the value of x. That means what we have to do is to isolate x-term first.
[tex]\huge{x+10=13}[/tex]
To isolate a variable means that to make a variable as a subject or also known as leaving a variable alone. To isolate the x-term for this problem, simply subtract both sides by 10 so we can get rid of 10 from the left side.
[tex]\huge{x+10-10=13-10}\\\huge{x+0=3}\\\huge{x=3}[/tex]
If you are not sure that the answer is correct or not. We can substitute the value of x in the equation.
[tex]\huge{x+10=13}[/tex]
Substitute x = 3 in the equation.
[tex]\huge{3+10=13}\\\huge{13=13}[/tex]
The equation is true for x = 3. Hence, we can conclude that x = 3 is the solution to the equation.
What do you need to do to solve the problem?

What is the sum of 4 and its additive inverse?

The additive inverse is the opposite sign quantity so the sum of 4 and its additive inverse will be 0.
What is summation?A summation, also abbreviated as a sum, is the outcome of adding two or more numbers or quantities. Here are always an integer number of terms in a summation.
Given the number 4.
The sign of the number 4 is positive.
An additive inverse is a number whose sign is opposite to the number.
For example, the additive inverse of -5 is 5, and 5 is -5.
So additive inverse of 4 will be -4.
Now sum of 4 and -4
4 + (-4) = 0
Hence "The additive inverse is the opposite sign quantity so the sum of 4 and its additive inverse will be 0".

What is the product of (x+3)(x-3)=7
Answer:
Step-by-step explanation:
What you have here is an equation with two roots. The "product" is (x + 3)(x - 3), which comes out to x^2 - 9.
Thus, you have x^2 - 9 = 7, or x^2 - 16 = 0, and the roots of that are {-4, 4}.
The camping trip costs $165. How long will it take you to save enough money?
25 Points I guess.
Answer:
11 weeks
Step-by-step explanation:
$165 / 15 = 11 weeks
11 weeks
Hope that helps!
The equation of line is given by y = 15x and the number of weeks to save enough money is 11 weeks
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the number of weeks be x
Let the cost of trip be y
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( 4 , 60 )
Let the second point be Q ( 8 , 120 )
Now , the slope of the line between the two points is
Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 120 - 60 ) / ( 8 - 4 )
On simplifying the equation , we get
Slope m = 60 / 4
Slope m = 15
Now , the equation of line is y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 60 = 15 ( x - 4 )
On simplifying the equation , we get
y - 60 = 15x - 60
Adding 60 on both sides of the equation , we get
y = 15x
Now , the cost of the camping trip is $ 165
Substitute the value of y = 165 , we get
165 = 15x
Divide by 15 on both sides of the equation , we get
x = 165/15
x = 11 weeks
Therefore , the value of x is 11 weeks
Hence , the equation is y = 15x
