A trader bought aTV set for Birr 2000 and sold it at loss of 5 1/2%. what was the selling price?
Answer: birr 1780.
Solution:
The cost price of the T.V. set = birr 2000
The loss percentage = 5 1/2%
The formula of the selling price is: Selling Price = (100 - Loss%)/100 × Cost Price
Now,
By using the above formula and by substituting the given values of C.P. and Loss%, we get
Selling Price = (100 - 11)/100 × 2000
Selling Price = 89/100 × 2000
Selling Price = 89 × 20
Selling Price = 1780
Thus, the selling price of the T.V. set was → birr Given:
A trader bought a TV set for birr 2000 and sold it at a loss of 11%
To find:
What was the selling price?
Solution:
The cost price of the T.V. set = birr 2000
The loss percentage = 11%
We know the formula of the selling price is:
Now,
By using the above formula and by substituting the given values of C.P. and Loss%, we get
Thus, the selling price of the T.V. set was → birr 1780.
Describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x).
f(x) = 9 cos x ; g(x) = cos x (3 points)
Answer:
The transformations required to obtain the graph of the function f(x) from the graph of the function g(x) is vertical stretch
Step-by-step explanation:
We need to describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x).
We have g(x) = cos x
After transformation we get
f(x)= 9 cos x
According to transformation rule:
if f(x) is transformed into a.f(x) then the transformation is vertical stretch or compression.
if a > 1 then transformation is vertical stretchif 0 < a < 1 then transformation is vertical compressionIn our case
g(x)= cos x
f(x) = 9 cos x
a=9 and a>1 so, the transformation is vertical stretch.
So, The transformations required to obtain the graph of the function f(x) from the graph of the function g(x) is vertical stretch

Answer:
first car : 115 liters
second car: 135 liters
Answer:
car 1 = 173.08 liters
car 2 = 76.92 liters
Step-by-step explanation:
the first step is to find what ratio of car 1 is to car 2
that is 18:8
total ratio is 26
the combination of car 1 and 2 = 26
the total km = 3350
total fuel = 250 liters
car 1 = 18 x 250 liters
26
= 173.08 liters
car 2 = 8 x 250 liters
26
= 76.92 liters
173.08 + 76.92 = 250
The longer leg of a right triangle has a length of 15. One angle in the triangle is 60 degrees. What is the length of the shortest leg?
The shortest side of a right triangle with a hypotenuse of 15 and one angle of 60° is 7.5
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Given that the longer leg of a right triangle has a length of 15, hence hypotenuse = 15. One angle in the triangle is 60°. Let x represent the shortest side.
The shortest side is adjacent to the 60° angle, hence:
cos(60) = x / 15
x = 7.5
The shortest side of a right triangle with a hypotenuse of 15 and one angle of 60° is 7.5

use SSS, SAS, ASA, AAS or HL star if the two triangles are congruent, if they are state how you know?
Answer:HL, ASA, SSS, ASA
Step-by-step explanation:
1. HL because the hypotenuse are equal by the reflexive property and the at least one pair of legs are congruent. Also the interior angles are congruent.
2. ASA because the interior angles are both congruent and the included side is congruent by the reflexive property.
3. SSS because the corresponding sides are congruent and the line is congruent by reflexive property so all the sides are congruent.
4. ASA because the interior angles are congruent and the other pair of angles are also congruent because they are verticle angles. The including sides are also congruent so therefore angle-side-angle.

Step-by-step explanation:
M= i + r ; solve for r
Answer:
m - i = r
Step-by-step explanation:
In this question, you are solving for "r".
Solve:
M= i + r
We have to get "r" by itself, so subtract "i" from both sides.
m - i = r
Since we found what "r" is, we can't solve any further.
m - i = r would be your answer.

The coach for a basketball team wants to try I buy new shoes for her 12 players.
The same shoes are available on double dribble’s web site for $57.75. A 9% processing fee will be applied to the cost of the shoes, plus a shipping fee of $5.99 for each pair.
What is the difference in the total costs of the 12 pairs of shoes between the two sites?
The difference in the total costs of the 12 pairs of shoes between the two sites is $46.77,
How to find the cost difference and total cost?Total cost is the sum up cost for all the individual process. we can find it by adding the cost for each steps.
In the given ques,
Super Sports is offering a 20% discount.
and shoes were originally priced at $72.50 and that a 6.5% sales tax will be applied.
On Double Dribbles, the same shoes were on for $54.75, and a 9% is added and has an extra $5.99 for shipping.
i.e. we have to find the difference in the total costs..
Now we have to multiply 12 by 72.50. The answer to that is 870. Next, we need to multiply 8 by 870 and divide it by 10. The answer to that is 696. Then, we need to add the price and the tax. The price will be 100%, and the tax will be 6.5%. 100 + 6.5 = 106.5. After that, we need to 106.5 by 100. The answer it that is 1.065. Now do times 1.065 by 696. And the answer to that is $741.24.
Do the same for other store. The answer to it is 788.01.
Thus, making Super Sports a better deal.
As, we need to find the difference. So, 788.01 - 741.24 = $46.77.

you measure the period of a mass oscillating on a vertical spring ten times as follows: period (s): 1.06, 1.31, 1.28, 0.99, 1.48, 1.37, 0.98, 1.31, 1.59, 1.55 what are the mean and (sample) standard deviation?
The mean and (sample) standard deviation σ = 0.2098.
What exactly would the standard deviation indicate?The term "standard deviation" (or "") refers to the degree of dispersion of the data from the mean. Data are grouped around the mean when the standard deviation is low, and are more dispersed when the standard deviation is high.
According to given information:The mean is the product of the dataset's total and the sample size. Mathematically.
[tex]\bar{x}=\frac{\sum X_i}{N}[/tex]
The individual periods are Xi.
The sample size is N.
[tex]\sum X i[/tex] = 1.06 + 1.31 + 1.28 + 0.99,+ 1.48 + 1.37+ 0.98 + 1.31 + 1.59 + 1.55
[tex]\sum X i[/tex] = 12.92
N = 10
While substituting the value we get:
x = 12.96/10
x = 1.292
The samples' average is 1.292.
The standard deviation:
[tex]\sigma=\sqrt{\frac{\sum(x-\bar{x})^2}{N}}[/tex]
[tex]\sum(x-\bar{x})^2[/tex] = (1.48-1.292)^2+(1.37-1.292)^2+(0.98-1.292)^2+(1.31-1.292)^2+(1.59-1.292)^2+(1.55-1.292)^2.
[tex]\sum(x-\bar{x})^2[/tex] = 0.43996
Putting into the formula we get:
[tex]\sigma=\sqrt{\frac{0.43996}{10}}[/tex]
σ = √(0.043996)
σ = 0.2098
The mean and (sample) standard deviation σ = 0.2098.
