Abel bought a mini hi-fi set for S600.
He sold it to Bob at a loss of 20%.
Bob sold it to Charles and made a profit of 5%. How much did Charles pay for it?
Answer:
$504
$600* .8 = $480
$480 * 1.05 = $504
Step-by-step explanation:
Answer:
Step-by-step explanation:
Abel:
Cost price = $ 600
Loss = 20%
Selling price = [tex]\frac{100-loss}{100}*Cost \ price[/tex]
[tex]= \frac{(100-20)}{100}*600\\\\=\frac{80}{100}*600[/tex]
= 80 * 6 = $ 480
Cost price for Bob = Selling price of Abel = $ 480
Bob's cost Price = $480
Selling price = [tex]\frac{100+Profit}{100}*CP\\\\[/tex]
[tex]= \frac{100+5}{100}*480\\=\frac{105}{100}*480[/tex]
= $ 504
Amount paid by Charles =$ 504
Which statement are true regarding undefinable terms in geometry
Answer:
A plane has an unlimited number of points.
Step-by-step explanation:
A plane has an unlimited number of points.
An exact solution represents a point's position on the coordinate plane (x, y).
Even though a point has no dimensionality, the second assertion is incorrect.
Because a linear has only one component, length, the third assertion is likewise incorrect.
a: A point has no length or width.
B: a point indicates a location in a coordinate plane.
E: a plane consists of an ifinite plans
F: a line consists of an infinite set of points.
A 3^{\text{rd}}3 rd 3, start superscript, start text, r, d, end text, end superscript degree binomial with a constant term of 88
Answer:
See explanation
Step-by-step explanation:
A 3rd degree binomial with a constant term of 8
A binomial expression is an expression which has only terms such as: x² + 5
The degree of a polynomial is the term with the highest exponent on its variable.
Example: the expression above x² + 5
The exponent of variable, x is 2
So, it is a 2nd degree polynomial
We also have 1st degree polynomial where the highest exponent on the variable is 1
3rd degree polynomial where the highest exponent on the variable is 3
A 3rd degree binomial with a constant term of 8
1. There must be a variable, let say x
2. The highest exponent on the variable must be 3
3. There must be a constant 8
4. The expression must have two terms only
It could be x² + 8 where the coefficient of x is 1
2x² + 8
3x² + 8
It could take any form as long as the highest exponent on the variable is 3 and there are just two terms

The fence posts need to be painted Each post is round with a diameter of 50mm and length of 2.5m. The posts are hollow (no top or bottom) Now work out the surface area of a single fence post
Answer:
0.3927 m²
Step-by-step explanation:
Since a post is open at both ends, then it means it has no top nor bottom and as such the surface area is;
S.A = 2πrh
Where;
r is radius
h is height
We are given;
diameter; d = 50mm = 0.05 m
We know that; radius = diameter/2 = 0.05/2 = 0.025 m
Height; h = 2.5 m
Thus;
S.A = 2 × π × 0.025 × 2.5
S.A = 0.3927 m²

5 – 2x = 3 what is x?
Answer: x=1
Step-by-step explanation:
To solve for x, we want to isoate the variable.
5-2x=3 [subtract both sides by 5]
-2x=-2 [divide both sides by -2]
x=1
Now, we know that x=1.
Answer:
X = 1
Step-by-step explanation:
Add 2x to both sides of the equation
5-2x+2x=3+2x
5+0=3+2x
Subtract 3 from both sides of the equation
5-3=3-3+2x
2=0+2x
2x=2
x=2/2
X = 1
Scarlett tried to shade all the factors of 15 on the hundred chart.What mistake did Scarlett make? A.Scarlett shaded the factors of 5 instead of the factors of 15. B.Scarlett did not make a mistake. C.Scarlett shaded the multiples instead of the factors of 15. D.Scarlett shaded 15, but factors are always less than the number.
Answer:
C. Scarlett shaded the multiples instead of the factors of 15
Step-by-step explanation:
Scarlett tried to shade all the factors of 15 on the hundred chart 15,45,75,30,60,90 What mistake did she make
She shaded 15,45,75,30,60,90 on the chart
Factors of 15 are 1, 3, 5 and 15
15, 45, 75, 30, 60, 90 are multiples of 15
That is,
15 × 1 = 15
15 × 3 = 45
15 × 5 = 75
15 × 2 = 30
15 × 4 = 60
15 × 6 = 90
Therefore Scarlett's mistake is:
C. Scarlett shaded the multiples instead of the factors of 15

Answer:
It's 2, 1, and y = 2x + 1.
Step-by-step explanation:
You can see the rise is 2 and the run is 1, making the slope = 2, and the y-intercept is 1 because that is where it crosses the y axis. Once you have the slope and y intercept, you can put it in a function, with the form being y=2x+1, the slope being the number before the x and the y-int value being after the x.
Answer:
1. 2
2. 1
3. y = 2x+1
Step-by-step explanation:

2. Where does the line cross the y-axis?
3. y = mx+b

3(4m - 3t)-2(m – 2t)
Answer:
10m-5t
Step-by-step explanation:
3(4m-3t) - 2(m-2t)
(12m - 9t) + (-2m+4t)
12m-2m - 9t+4t
10m-5t
Answer:
Step-by-step explanation:
3(4m - 3t) = 12m - 9t
-2(m - 2t) = -2m + 4t
Write the 2 terms together.
12m - 9t -2m + 4x
12m - 2m - 9t + 4t

Find sin X.
a. sin X= 4/5
b. sin X= 3/4
c. sin X= 3/5
d. sin X= 5/4
Answer:
sin X = 4/5
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin X = opp side/ hypotenuse
sin X = 36/45
= 4/5
Let's find the value of sin X,
→ opp/hyp
→ 36/45
→ 4/5
The required answer will be,
→ a. sin X= 4/5
So, option (a) is the answer.

What is reflection of (5, 15) across the x-axis?
Answer:
(5 , -15)
Step-by-step explanation:
When you are reflecting over the x-axis, you are flipping the sign of the y-coordinate.
If you are reflecting over the y-axis, then you are flipping the sign of the x-coordinate.
In this case, you are given the point (5 , 15), and you are reflecting over the x-axis, in which case, your answer will be: (5 , -15).
~
Answer:
Step-by-step explanation:
In this question, we are asked to find the point of reflection across the x-axis.
The easiest way to find reflection is to find the equal distance from the current point to the x-axis, then apply it reversely to find the reflected point.
The vertical point from (5, 15) to the x-axis is (5, 0).
Then, we need to find the distance from (5, 15) to (5, 0)
15 - 0 = 15 unitsAs we know the distance from (5, 15) to (5, 0) is 15 units, then we apply this to the other side of the x-axis by subtraction
0 - 15 = -15 unitsTherefore, the reflected point is (0, -15)

Answer: c = 72
Step-by-step explanation:
You didn't tell us which segment has a length of c, but I'm assuming you meant WX because it corresponds to PA. If two figures are similar, we know that their side length are in proportion. With this, we can set up our proportion[tex]\frac{18}{24} =\frac{c}{96}[/tex] where c is the length of WX. By cross multiplying and dividing, you get 72 for the value of c.

What is the x-intercept of the line with equation 3y - 8x = 10? Represent your answer as a point in (x, y) form.
The solution is
Answer:
(-1.25, 0) or (-5/4, 0)
Step-by-step explanation:
The x-intercept is when y = 0, so let's plug 0 into the equation:
3(0) - 8x = 10
Now we use basic algebra to solve for x:
0 - 8x = 10
-8x = 10
x = -5/4 or -1.25
So the answer is (-1.25, 0) or (-5/4, 0).

Assume that the radius of the hydrogen nucleus is 1.4 · 10-15 meters. How much larger than the nucleus is the entire hydrogen atom? (Calculate the atomic radius for n = 1. Round answer to nearest tenth.)
________times larger than the nucleus.
(A). 3.8 x 10⁴
(B). 3.8 x 10¹⁴
(C). 3.8 x 10^-5
(15 points reward)
Answer:
A
Step-by-step explanation:
I did not look up the actual numbers, but it can only be A.
of course, the whole aim is larger than the nucleus, which is why C is impossible with its negative exponent (which would make the whole aim smaller than the nucleus).
and B. can't be true, because it is so big 10¹⁴ times bigger than a 10-¹⁵ atom ? this would make the whole atom the size of about 10-¹ meters. so, 10 cm. a single hydrogen atom would be bigger than a tennis ball. which it isn't.
so, that only leaves A.
