A person sold a desk for rs. 400 and incurred a loss of 5%
approximately at what price would it be sold so as to earn
a profit of 6%?
a) 420
b)478
c)446
d)432
Answer: C
Step-by-step explanation:
1% of Rs. 400 = 4
10% of Rs.400 = 40
5%= 20
400+20= Rs. 420 was the price the person may have bought it for
To get a 6% profit, we need to add 6% on top of the price the chair was bought for by the owner
so...
420+ 5% +1%
so..
420+20+4= 444
The answer has come to 444 whereas it is not an option as a possible answer and I am unable to see a miscalculation in my working so if anyone spots a mistake it would be much appreciated. I have gotten a value close to one of the possible answers therefore I think the answer most probably should be "C" according to my working, however it may be that the person typing in the question may have written the incorrect options. Either way I have come to a conclusion and if it happens to be a typing error my maths was correct, if no, someone please reach out to me and help me identify where I have gone wrong, Thank you.
Jasmine's credit card has a $2,000 balance that she carried over from last month. assuming her credit card charges an 18 percent annual interest rate, how much will her interest charges be this month?
Using simple interest, it is found that her interest charge this month will be of $30.
Simple InterestSimple interest is used when there is a single compounding per time period.
The amount of interest after t years in is modeled by:
I(t) = Prt
In which:
P is the initial amount.r is the interest rate, as a decimal.In this problem, considering the time in years, the parameters are:
[tex]P = 2000, r = 0.18, t = \frac{1}{12}[/tex]
Hence:
[tex]I(t) = 2000 \times 0.18 \times \frac{1}{12} = 30[/tex]
Her interest charge this month will be of $30.

Isaiah is jogging near his college. he runs south along capitol street for about 0.75 miles and east along h street for about 1.2 miles. he then turns left and runs along florida avenue until he reaches his starting point. how long is his total run to the nearest hundredth of a mile? a triangle. the sides are capitol street, h street, and they hypotenuse is florida avenue. 2.89 miles 3.37 miles 3.67 miles 3.92 miles
The total distance he travelled to the nearest hundredth of a mile is; B: 3.37 miles
How to work with Pythagoras Theorem?Let F represents his starting point.
Let C represent his position from where he went to east direction.
Let H represent his position from where he went to left towards Florida Avenue.
We are given that;
FC = 0.75 miles
CH = 1.2 miles
∠FCH = 90°(This can be deduced from the question)
By Pythagoras theorem, we have;
FH = √(0.75² + 1.2²)
FH = 1.42
Thus;
Total distance he covered = FC + CH + FH
Total distance covered = 0.75 + 1.2 + 1.42
Total distance covered = 3.37 miles

There are a total of 165 dogs and cats waiting for homes at the Grand Strand Humane Society. The number of cats is 24 less than twice the number of dogs.
Part A: Identify both variables you are using, then write equations to represent both situations
Part B: How many dogs and cats are waiting to be adopted in the shelter? You must show work. Write your answer in the form of a sentence
Answer:
Part A
Let d = number of dogs
Let c = number of cats
Given:
total of 165 dogs and cats⇒ d + c = 165
Given:
The number of cats is 24 less than twice the number of dogs⇒ c = 2d - 24
Part B
Substitute c = 2d - 24 into d + c = 165 and solve for d:
⇒ d + 2d - 24 = 165
⇒ 3d - 24 = 165
⇒ 3d = 189
⇒ d = 63
Substitute found value of d into d + c = 165 and solve for c:
⇒ 63 + c = 165
⇒ c = 102
Therefore, 63 dogs and 102 cats are adopted in the shelter.

Enter your answer as a decimal in the box. Use 3.14 for pi and round only your final answer to the nearest hundredth.
Answer:
v = 3,463,118,874
Step-by-step explanation:
2214 * 225 = 498,510
diameter = 498,510
v = pi(d) * h
v = 3.14(498,510) * 2214
v = 1,564,191 * 2214
v = 3,463,118,874

A ship travels 40 miles due east, then adjusts its course 12° southward. After traveling 70 miles in that direction, how far is the
ship from its point of departure?
The ship movement is an illustration of distance and bearing
The ship is 31.97 miles from its point of departure
The distance from the point of departure?
The given parameters are:
Distance east = 40 miliesDistance southwards = 70 milesAngle = 12 degreesSee attachment for the image of the above parameters
The distance (x) from the point of departure is then calculated using the following cosine function
a^2 = b^2 + c^2 - 2bc * cos(Ф)
So, we have:
x^2 = 40^2 + 70^2 - 2 * 40 * 70 * cos(12)
Evaluate the exponent and the product
x^2 = 6500 - 5477.63
Evaluate the difference
x^2 = 1022.37
Evaluate the exponent
x = 31.97
Hence, the ship is 31.97 miles from its point of departure

Is (10, 8) a solution to this system of equations?
2x - 5y = -20
X + 9y = 14
A
O a. Yes
b. No
Answer: No, there isn't anything showing that it is.
No
Step-by-step explanation:
Substitute value of x (10) & y (8) in both equation
x + 9y =14
10 + 9 x 8 = 82
(doesn't give us the output of 14)
2x - 5y = -20
2 x 10 - 5 x 8 = - 20
(this does, but both have to work)
Solution is at (-4.8,2.1):
2x +18y =28
2x - 5y = -20
(minus)
(18 - - 5 & 28 - - 20 those minus becomes a + )
23y = 48
÷23
y= 48/23
(2.1 to 1d.p)
Substitute y to find x
2x - 5y = -20
2x - 5 x 48/23 = - 20
2x - 240/23 = - 20
+240/23
2x = -220/23
÷2
x = - 110/23
X= -4.8 to 1d.p
(-110/23, 48/23)

Sophia invests money in an account paying simple interest. She invests $70 and no money is added or removed from the investment. After one year, she has $72.80. What is the simple percent interest per year?
Answer:
72.80= 70(x)^1
x^1 is still x, so leave it at 72.8= 70x
divide 70 from both sides to leave x by itself
x= 1.04
