A watch seller gained 20% by selling a watch for 1260.If he had to gain 30%,at what price should have he sold it?
Dalton III
Answered December 12, 2020
I shall explain the solution to this problem using rudimentary concepts.
First, we need to determine the original price of the watch.
Convert the percentage profit to a decimal by dividing by 100. In this problem, the profit is 20%, so we would divide:
20100=0.2
Add 1 to the profit expressed as a decimal.
1+0.2=1.2
Divide the price after the profit has been added by the figure which we have calculated to find the price before the profit (we shall assume that the currency used in this problem is the pound sterling)
£12601.2=£1050
Now that we have determined the original price of the watch, we shall determine at what price should the seller sell this watch in order to obtain a 30% gain. The same formula is used for the first two steps.
Convert the intended percentage profit to a decimal by dividing by 100. In this problem, the intended profit is 30%, so we would divide:
30100=0.3
Add 1 to the intended profit expressed as a decimal.
1+0.3=1.3
Now, instead of dividing, we would want to multiply the original price with the figure 1.3
£1050⋅1.3=£1365
So, in order to gain a profit of 30%, the watch seller should sell the watch at a price of £1365
What is the measure of the angle that the ladder makes with the wall?
Answer:
30°
Step-by-step explanation:
The measure of angle the ladder makes with the wall = 180 - (the measure of angle the ladder makes with the ground + 90°)
Measure of angle the ladder makes with the ground = 180 - 120 = 60°
Therefore,
The measure of angle the ladder makes with the wall = 180 - (60 + 90°)
= 30°

Diver Dan enjoys scuba diving. He dives to 34 feet below the surface of a lake. His friend Jump in Jeff dives to 40 feet below the surface, but then descends 20 feet. What is the vertical distance between Dan and Jeff? Please show work.
Answer:
The vertical distance between Dan and Jeff is of 26 feet.
Step-by-step explanation:
Diver Dan enjoys scuba diving. He dives to 34 feet below the surface of a lake.
His position is -34 feet.
His friend Jump in Jeff dives to 40 feet below the surface, but then descends 20 feet.
Dives to 40 feet, and descends 20 more feet. So
-(40 + 20) = -60
What is the vertical distance between Dan and Jeff?
|-34 - (-60)| = |-34 + 60| = 26
The vertical distance between Dan and Jeff is of 26 feet.

Find the volume of the beach ball and the volume of the toy ball. How many times greater is the volume of the beach ball than the volume of the toy ball?
A.THE VOLUME OF THE BALL IS 904 CUBIC INCHES. b. THE VOLUME OF THE BEACH BALL IS 678 CUBIC INCHES. c.the volume of the beach ball is 452 cubic inches
Answers:
Volume of beach ball = 904 cubic inchesVolume of toy ball = 113 cubic inchesThe beach ball is 8 times greater compared to the toy ball===============================================
Work Shown:
Beach ball
V = volume of sphere
V = (4/3)*pi*r^3
V = (4/3)*3.14*(6)^3 .... the beach ball has diameter 12, so radius is 6
V = 904.32
V = 904 cubic inches is the approximate volume of the beach ball
------------------------
Toy ball
V = volume of sphere
V = (4/3)*pi*r^3
V = (4/3)*3.14*(3)^3 .... the toy ball has diameter 6, so radius is 3
V = 113.04
V = 113 cubic inches is the approximate volume of the toy ball
--------------------------
Divide the two volumes to find that 904/113 = 8
This means that the beach ball is 8 times greater in volume compared to the toy ball
We can say
[tex]\text{Beach ball volume} = 8*\left(\text{toy ball volume}\right)[/tex]
The beach ball's volume is 7238.23and if we round that would be 7238 and the volume for the toy ball is 904.78 and if we round that it would be 905.So, it's around 7 times greater. The difference after they are rounded is 6,333.
Hope this helps.

What is the sale price of a bag of potato chips priced 4 and the sale 25% off?
A:$1.50 B:$2 C:$3 D:$2.50
Answer:
C: $3
Step-by-step explanation:
I think you're saying that the chips cost $4, so that's what I'm going with.
You can think of 25% as 1/4 of the whole. So if you divide 4 by 4, you get 1, so that means that 1/4 of the price is 1.
Now you can subtract 1 from 4 : 4-1= $3
Hope that helps!

Answer:
3. One Solution. (0,4). (they have different slopes and y-intercepts)
The solution can be found using elimination method:
Add the equations together
y = -x + 4
y = x - 4
2y = 0
y = 0
Solve for x
0 = x - 4
x = 4
(4, 0)
4. No solution

Scarlett walks along the edges of a
rectangular path from A to B to C to D, a
distance of 38 metres. Jake walks along the
same rectangle, but from B to C to D to A,
a distance of only 31 metres.
What is the area, in square metres, of rectangle ABCD?
D
С
Answer:
168 meters squared
Step-by-step explanation:
So we know that Jake walked from b to c and d meaning he didn't go from a to b, but we also know that scarlet walked a to b so to find the length we can subtract scarlet's walk by jake's walk or 38-31 which is 7.
So we know the length of one side is 7 so this means we have side a to b and c to d, but we still need to know b to c. So what we can do is get the length of a b c and d and isolate it so that we only have b to c. To do this we get the length of 7 and double it which is 14 and take it away from the 38m
38-14=24
so now we know that the side is 24 and we can solve for the area
24*7=168
so the answer is 168 meters squared

48 is 12% of what number?
Answer:
I'm not sure but from my calculations,it is 400
Answer:
400
Step-by-step explanation:
In order to find out a percentage of something you divide the percent by 100 (12/100) to get a decimal, which would be 0.12. Now with this we already know 12% of something is 48 and in order to find what we took 12% from we divide 48 by 0.12.
48÷0.12 or 48/0.12 = 400

Solve the following quadratic equation for all values of x in simplest form.
20+ 2x= 28
Answer:
x = 4
Step-by-step explanation:
To solve, we need to isolate x.
Start by moving the 20 to the other side by subtracting it from both sides.
2x = 8
Since x is being multiplied by 2, we need to divide both sides by 2 to move it to the other side.
x = 4
Enter the equations of the asymptotes for the function f(x).
f(x)=−2x+4−6
Vertical asymptote:
Horizontal asymptote:
Answer:
Vertical Asymptote: -4
Horizontal Asymptote: -6
Step-by-step explanation:
Using it's concepts, it is found that:
There is a vertical asymptote at x = 4.There is a horizontal asymptote at y = -6.What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.In this problem, the function is given by:
[tex]f(x) = -\frac{2}{x + 4} - 6[/tex]
Hence:
[tex]x + 4 = 0 \rightarrow x = 4[/tex]
There is a vertical asymptote at x = 4.
As for the horizontal:
[tex]y = \lim_{x \rightarrow 0} -\frac{2}{x + 4} - 6 = -\frac{2}{\infty + 4} - 6 = -0 - 6 = -6[/tex]
There is a horizontal asymptote at y = -6.

Make a table with the following information:
Cans: 0, 2, 4, 6
Cost:
Equation:
Answer:
$12,$11,$10,$9
Step-by-step explanation:
As the starting price is $12, the first piece of information they give you is the number of cans + the discount each one gives, meaning that the table should have two titles being cost and cans. The number of cans should be at the top with the price being put below for example.
cans: 0 2 4 6
cost: 12 11 10 9
that is the table; the equation to figure this out would be
if you say that 1 can is = to "x"
then the equation becomes much easier to write down and you can simply write it down for each price
cost = 12
cost = 12 - 2x = 11
cost = 12 - 4x = 10
cost = 12 - 6x = 9
