the price of a ring was decreased by 25% to £390. what was the price before the decrease?

Answers

Answer:

The original price was 520

Step-by-step explanation:

To find this, we first need to note that we paid 75% of the price. This is because we took 25% off from the original. Now we take the price we paid and divide it by the percentage of it which we paid. This will give us the original price.

390/75% = Total

390/.75 = Total

520 = Total

Find the value of x.

Answers

12^2+x^2=15^2
144+x^2=225
- 144 -144
=81= 9
X=9

Answer:

x=9

Step-by-step explanation:

Use Pythagorean Theorem -> a^2 + b^2 = c^2

a^2 + b^2 = c^2

(12^2) + b^2 = (15^2)

144 + b^2 = 225

225 - 144 = 81

√81 = 9

x = 9

Step-by-step explanation:

Answer:

x = 4[tex]\sqrt{3}[/tex], y = 8[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Using the tangent ratio in the right triangle and the exact value

tan30° = [tex]\frac{\sqrt{3} }{3}[/tex] , then

tan30° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{12}[/tex] = [tex]\frac{\sqrt{3} }{3}[/tex] ( cross- multiply )

3x = 12[tex]\sqrt{3}[/tex] ( divide both sides by 3 )

x = 4[tex]\sqrt{3}[/tex]

------------------------------------------------------------

Using Pythagoras' identity in the right triangle

y² = x² + 12² = (4[tex]\sqrt{3}[/tex] )² + 144 = 48 + 144 = 192 ( take square root of both sides )

y = [tex]\sqrt{192}[/tex] = [tex]\sqrt{64(3)}[/tex] = 8[tex]\sqrt{3}[/tex]

Determine if the following ratios form proportions.

1.) 1 to 3 and 7 to 21

2.) 3 to 4 and 24 to 18

3.)1:5 and 6:30

for brainiest:)

Answers

Answer:

1. Proportional

2. Not proportional

3. Proportional

Step-by-step explanation:

We have three questions with 2 ratios and are asked if they are proportional or not.

To define proportionality, basically its if the two ratios equal the same value when put in a certain way.

And that way is :

[tex]\frac{x}{y} =\frac{x}{y}[/tex]

You will substitute the numbers with the letters, in which you will cross multiply :

[tex]\frac{x * y}{x*y}[/tex]

So subtitute :

1.

[tex]\frac{1}{3} *\frac{7}{21}[/tex]

[tex]\frac{1*21}{7*3}[/tex]

[tex]21=21[/tex]

Therefore 1. is proportional.

2.

[tex]\frac{3}{4} *\frac{24}{18}[/tex]

[tex]\frac{4*24}{3*18}[/tex]

[tex]\frac{96}{54}[/tex]

96 = 54

Therefore 2. is not proportional.

3.

[tex]\frac{1}{5} *\frac{6}{30}[/tex]

[tex]\frac{1*30}{5*6}[/tex]

[tex]\frac{30}{30}[/tex]

30 = 30

Therefore 3. is proportional.

Describe how to find the slope and y intercept of 2x+3y=6, then describe how would you graph the line.

Answers

so you would subtract the 2x from both sides so you’d get 3y=6-2x then you divide all the numbers by 3 to get Y by itself so you’ll get Y=2-2/3X then to graph the Y intercept is 2 so you place your first point at (0,2) then your next point you go down 2 then right 3 and keep doing that and placing points and that’s your line on the graph :)

Triangle ABC has vertices A(-5, -1), B(5, -1), and C(0, -4). Is it scalene, isosceles or equilateral

Answers

Answer:

Isosceles Triangle

Step-by-step explanation:

Triangle ABC has vertices A(-5, -1), B(5, -1), and C(0, -4). Is it scalene, isosceles or equilateral?

We solve this question using vertices formula:

√(x2 - x1)² + (y2 - y1)² when given vertices: (x1, y1) and (x2 , y2)

For Side AB

A(-5, -1), B(5, -1)

AB = √(5 - (-5))² + (-1 -(-1))²

AB= √(5 + 5)² + (-1 + 1)²

AB = √10² + 0

AB = √100

AB = 10 units

For Side BC

B(5, -1), C(0, -4)

BC = √(0 - 5)² + (-4 -(-1))²

BC = √-5² + (-4 + 1)²

BC = √25 + -3²

BC = √25 + 9

BC = √34

For Side AC

A(-5, -1), C(0, -4).

AC = √(0 - (-5))² + (-4 - (- 1)²

AC = √5² + -3²

AC = √25 + 9

AC = √34

Therefore this triangle is an isosceles triangle because 2 of its sides (AC and BC ) are equal to one another
