Answer:

Percentage profit = 20%

Step-by-step explanation:

Given the following data;

Cost price = birr 180

Selling price = birr 225

To find the percentage profit;

First of all, we would determine the profit;

Profit = selling price - cost price

Profit = 225 - 180

Profit = birr 45

Next, we would determine the percentage profit;

[tex] Percentage \; profit = \frac{profit}{selling \; price} * 100[/tex]

[tex] Percentage \; profit = \frac{45}{225} * 100[/tex]

[tex] Percentage \; profit = 0.2 * 100[/tex]

Percentage profit = 20%

Answer:

a=9

divide 81 by 9 on both sides and you get 9.

Step-by-step explanation:

Answer:

a = 9

Step-by-step explanation:

To solve this equation for a, divide both sides by 9.  

The result is a = 81/9, or a = 9.

Answer:

y=(-5/2)x+3

Step-by-step explanation:

5x+2y-8=0

2y=-5x+8 Divide with 2

y=(-5/2)x+4

Slope is dy/dx

dy/dx=-5/2

x+4y-12=0 for x=0

4y-12=0

4y=12 Divide with 4

y=3 y-intercept

Line equation:

y = mx + b

This is called the slope-intercept form because "m" is the slope and "b" gives the y-intercept.

m-5/2 b=3

Euation for the your line:

y=(-5/2)x+3

Answer:

isn't that the same as before? :D

Hi there!

I believe your answer is:  

[tex]\frac{83+97+80+g}{4} \geq 85[/tex]

»»————-　★　————-««  

Here’s why:  

⸻⸻⸻⸻

[tex]\frac{83+97+80+g}{4} \geq 85[/tex]

⸻⸻⸻⸻

The numerator would consist of the test grades and the unknown 'g' and the denominator would be the number of tests he taken.

"At least" indicates a greater than or equal to inequality.

Answer:

A. 900 un³

Step-by-step explanation:

Volume = Area triangle x height

Area triangle = 1/2 (15 x 8) = 1/2(120) = 60

60 x 15 = 600 + 300 = 900 un³

Answer:

b

Step-by-step explanation:

Answer:

y = 1/2x - 3/2

Step-by-step explanation:

y2 - y1 / x2 - x1

5 - (-4) / 13 - (-5)

9 / 18

1/2

y = 1/2x + b

-4 = 1/2(-5) + b

-4 = -5/2 + b

-3/2 = b

Answer:

2 1/6 or 13/6

Step-by-step explanation:

Equation: [tex]\frac{1}{3}[/tex] × 6[tex]\frac{1}{2}[/tex]

Distribute: (1/3) ( 6 + 1/2)

(1/3)(6) + (1/3)(1/2)

2 + 1/6

2 1/6 or 13/6

Answer:0.007

Step-by-step explanation: the number after 6 is more than half of ten,therefore it is added to 6 as 1.To leave you with one significant figure.

0 is insignificant

Answer: An equation is *629 = n - 99. The geometry book has 728 pages*

Step-by-step explanation: The Algebra book has 99 pages LESS than the geometry book, in other words, the geometry book has 99 pages MORE than the Algebra book. This equation can be used to find the answer. I’m afraid 530 is not the answer.

Hope this helps! :)

Answer:

|-1/4 - 3/4|

Step-by-step explanation:

To get the distance, take the absolute value of the second point minus the first point

| 3/4 - - 1/4|

|3/4 +  1/4|

We can also  take the absolute value of the first point minus the second point

|-1/4 - 3/4|

Answer:

11.43

Step-by-step explanation:

You can start this by adding the total cost of the salad and the coffee.

4.76 + 3.81 = 8.57

Then you have the paid amount of 20 bucks because there was two tens.

20 - 8.57 = 11.43.

Answer:

p' (4,-2)

Step-by-step explanation:

P is at ( -1,5)

We are moving it 5 units to the right so add 5 to the x

We are moving it 7 units down so subtract 7 from the y

p'( -1+5, 5-7)

p' (4,-2)

Answer:

a dilation with a scale factor greater than 1 and then a translation (the last option)

The composition of transformation is a dilation with a scale factor greater than 1 and then a translation.

A translation only moves a shape up, down, or from side to side; it has no effect on how it appears.

We have a transformations maps LMN to  L'M'N'.

As the size of Triangle L'M'N' is larger as compared to LMN.

The compression is represented by a scale factor with an absolute value between 0 and 1, while the enlargement is represented by a scale factor with an absolute value greater than 1.

Thus, dilation with a scale factor greater than 1 and then a translation.

Given:

θ is an angle in standard position.

Its terminal side passes through the point (6,1).

To find:

The exact value of secθ in simplest radical form.

Solution:

If θ is an angle in standard position and its terminal side passes through the point (x,y), then the exact value of secθ is:

[tex]\sec\theta =\dfrac{Hypotenuse}{Base}[/tex]

[tex]\sec\theta =\dfrac{\sqrt{x^2+y^2}}{x}[/tex]

It is given that θ is an angle in standard position and its terminal side passes through the point (6,1), then the exact value of secθ is:

[tex]\sec\theta =\dfrac{\sqrt{6^2+1^2}}{6}[/tex]

[tex]\sec\theta =\dfrac{\sqrt{36+1}}{6}[/tex]

[tex]\sec\theta =\dfrac{\sqrt{37}}{6}[/tex]

Therefore, the exact value of secθ is [tex]\dfrac{\sqrt{37}}{6}[/tex].
