a Robin buys a watch for £80 He sells the watch for £56 Work out his percentage loss.
Based on the price that Robin bought the watch and the price he sells it, his percentage loss is 30%.
How much loss did Robin incur?This can be found by the formula:
= (Selling price - Purchase price) / Purchase price x 100%
Solving gives:
= (56 - 80) / 80 x 100%
= 24 / 80 x 100%
= 30%
In conclusion, Robin suffered a 30% loss.

Given circle Q with diameter OP and radius QM. MN is tangent to Q at M. If MO=9 and OP=10, solve for MP.
The length of side MP in circle Q is 4.36.
What is a circle?A circle is the locus of a point such that its distance from a fixed point known as the center is always constant.
From the circle:
∠OMP = 90° (angle in a semicircle)
Hence using Pythagoras theorem:
OP² = MP² + MO²
10² = 9² + MP²
MP = 4.36
The length of side MP in circle Q is 4.36.

The measure of m<FEJ is 75 degree
How to find the angles in kiteFrom the given figir, we can see that;
m< FHG = m< EFJ = 15 degrees
Since the sum of angles in a triangle is 180 degrees, hence;
m< EFJ + 90 + m<FEJ = 180
15+ 90 + m<FEJ = 180
m<FEJ = 180 - 105

The following numerically ordered sequence of numbers has a mean of 19 and a median of 24.
3,a,10,13,22,b,27,27,28,30
Given this information, find the values of a and b.
a=?
b=?
Answer:
a = 4
b = 26
Step-by-step explanation:
median is the middle number(s)
middle numbers are 22 and b
if the median is 24 then
that means the average if 22 and b is 24
so do the math in reverse
22 and b are 2 numbers
24 * 2 = 48
22 + b = 48
48 - 22 = 26
b = 26
mean is average
so do the math in reverse
there are 10 numbers
the average or mean is 19
so all the numbers add up to 190
3+a+10+13+22+26+27+27+28+30 = 190
a + 186 = 190
a = 4

Work out the value of x.
The diagram is not drawn accurately.
Answer:
x = 101 degrees
Step-by-step explanation
Answer:
x = 101°
Step-by-step explanation:
x and are same- side interior angles and sum to 180° , then
a + x = 180° , that is
79° + x = 180° ( subtract 79° from both sides )
x = 101°
Find the y-intercept of the parabola y = x2 + 3x.
Answer:
(0,0)
Step-by-step explanation:
The y-intercept is where the parabola crosses the y-axis. The y-intercept is expressed as a coordinate pair, where x is always equal to 0 because the y-axis exists where x=0.
There are 2 ways to find the y-intercept of a function. The first way is to plug in 0 for x because you know that x=0 at the y-intercept. Then, solve for y.
First, plug-in 0 for x[tex]y=0^2+3(0)[/tex]
Then, simplify the equationy=0
Since y=0, the y-value of the intercept is 0. Thus making the y-intercept (0,0).The second, and easier, way to find the y-intercept is to use logic. Since you are plugging in 0 for x, all terms that have variables will equal 0. This means that all that is left are the constants. So, the easiest way to find the y-intercept is to just simplify the constants. Whatever this equals will be the y-value of the y-intercept. Since there are no constants written in this equation, the constant must be 0. If 0 is the constant, then that must mean that the y-value of the intercept is 0.

The drawing is a scale drawing of a house.
An illustration of a house has its height labeled nine inches.
If the scale is 2 inches = 4.5 feet, what is the actual height of the house? Round to the nearest hundredth.
Answer: 20.25ft
1. Find what 8 inches in scale equal for the height of the house.
we will do this step by multiplying.
2in=4.5
8=?
to find...
2x4=8
so
4.5x4=18
2. Find what 1 inch on the scale is equal to for the height of the house.
we will do this by dividing 4.5 by 2
4.5/2=2.25
3. Add both the values for step 1 and 2.
we will do this by just adding them both
18+2.25=20.25
Why is this our answer?
This is our answer, because first we found the value of 8 inches on the scale, which means that we are finding almost the full value of the 9 inches of the height of the house, then, we found 1 inch because 9-8=1, so if we already found 8, which is a number in the table of 2, we found out 1 so that we can add it with 8 to find the value of 9in on the scale. In this way, after adding, that gives us the value of 9in on the scale!

∠1 & ∠2 are alternate exterior angles. Alternate exterior angles are congruent.
∠1 = ∠2
∠1 = 77°
The best answer gets 100 points. A number is equal to twice a smaller number plus 3. The same number is equal to twice the sum of the smaller number and 1. How many solutions are possible for this situation?
Infinitely many solutions exist because the two situations describe the same line.
Exactly one solution exists because the situation describes two lines that have different slopes and different y-intercepts.
No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.
Exactly one solution exists because the situation describes two lines with different slopes and the same y-intercept.
Answer:
No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.
Step-by-step explanation:
Let larger number be X and smaller one be Y.
The two equations are :-
X = 2Y + 3
X = 2Y + 1
As you can tell, the slopes are the same and the y-intercepts are different. So, they will not intersect. Therefore, no solutions exist for this situation.

Probability helps us to know the chances of an event occurring. The correct option is A.
What is Probability?Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Given that an integer is needed to be chosen between 1 to 50 both inclusive. Therefore, the most likely integer to be chosen can be known by finding the probability.
A.)The integer selected will be even.
Probability of choosing Even number = 25/50 = 0.5
The integer selected will be a multiple of 5.
Probability of choosing a multiple of 5 = 10/50 = 0.2
The integer selected will be a multiple of 10.
Probability of choosing a multiple of 10 = 5/50 = 0.1
The integer selected will be a multiple of 20.
Probability of choosing a multiple of 20 = 2/50 = 0.04
Since the probability of choosing an even number is the greatest, therefore, the integer that is most likely to be selected will be even.
