Answer:

All you have to do is image flipping the triangle on the right over and then you'll see they are equal. You can also look at AB and DE and see they both are right angles.

Answer:

the cost price of manufacturer = RS. 14.80

Step-by-step explanation:

the retailers profit = profit percent of sold amount

= 25% of 30.09

= 25/100 × 30.09

= 7.5225

here, the cost price of retailer =

sold amount- profit amount

or, CP = 30.09 - 7.5225

= 22.5675

now, profit of whole seller =

profit% of sold amount

or, 20% of SP

20/100 × 22.5675

= 4.5135

CP = SP - Profit

or, CP = 22.5675- 4.5135

CP = 18.054

now, profit of manufacturer = profit℅ of SP

= 18% of 18.054

= 18/100 × 18.054

= 3.24972

or, CP of manufacturer = SP - profit amount

= 18.054 - 3.24974

= 14.80428

Therefore, cost price of manufacturer = 14.80

Answer:

Step-by-step explanation:

w (width) = 32/8

w = 4

p (perimeter) = 2w + 2l

p = (2 x 4) + (2 x 8)

p = 8 + 16

p = 24

Answer:

x = 0, y = - 100

Step-by-step explanation:

So plug in the points you have which is x = 0.

50(0) + y = -100

0 + y = -100

y = -100

So, x = 0, y = - 100

Step-by-step explanation:

ok so im really bad at explaining but ill try my best.

so since its asking you to fiure out how much he watched in total, youre going to have to add.

for one of the videos he watched 5/8 mins and for the other 1/8 mins.

5/8 + 1/8= 6/8

and since its asking for its simplest form youre gong to have to simplify it

6/8=3/4

Hey there!

2/3x + 5 = 1

SUBTRACT 5 to BOTH SIDES

2/3x + 5 - 5 = 1 - 5

SIMPLIFY IT!
2/3x = 1 - 5

2/3x = -4

MULTIPLY 3/2 to BOTH SIDES

2/3x * 3/2 = -4 * 3/2

SIMPLIFY IT!

x = -4 * 3/2

x = -6

Therefore, your answer is: x = -6

Good luck on your assignment & enjoy your day!

Answer:

2/3x + 5=1

To solve for x, we must isolate it by administering inverse operations.

In this equation, we can see 2/3x is being added to 5.

We should discard the constants first.

The inverse operation of addition, is subtraction.

So we subtract 5 from both sides;

-5        -5

2/3x = -4

Now, we are left with a coefficient, so to get rid of the coefficient we utilize the inverse operation of multiplication, which is division.

Dividing by 2/3 is the same as multiplying by 3/2.

So multiply both sides by 3/2;

*3/2    *3/2

x = -4(3)/2

x = -12/2

x = -6

Answer:

-12; 5

Step-by-step explanation:

x^2 + 7x - 60 = 0

D = b^2 - 4ac

D = 7 * 7 + 60 * 4 * 1 = 289

sqrt(D) = sqrt(289) = 17

x₁ = (-b - √D) / 2a = (-7 - 17) / 2 = -24 / 2 = -12

x₂ = (-b + √D) / 2a = (-7 + 17) / 2 = 10 / 2 = 5

Answer:

12%

Step-by-step explanation:

Read a book = 16%

Listen to music = 28%

We can read the question in different ways:

1.  The simple difference between the two is 12%

2.  Out of the sample, the two groups include:

    15 chose books

    35 chose music

    Within this sample of 50 teenagers,

           (15/50) or 30% chose books, and

            (35/50) or 70% chose music

             That makes a difference of 40%

I would chose the first interpretation, 12%  [Especially since 40% is not an option.]

The product of (2x+y) and (5x-y+3) is (10x²+3xy+6x-y²+3y).

Polynomial is an expression that consists of indeterminates(variable) and coefficient, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.

The product of the two given polynomial (2x+y) and (5x-y+3), can be written as,

[tex](2x+y) (5x-y+3)\\\\= 10x^2-2xy+6x+5xy-y^2+3y\\\\=10x^2-2xy+5xy+6x-y^2+3y\\\\=10x^2+3xy+6x-y^2+3y[/tex]

Hence, the product of (2x+y) and (5x-y+3) is (10x²+3xy+6x-y²+3y).

Similar triangles may or may not have congruent sides lengths

From the properties of similar triangles, the side lengths of similar triangles may or may not be congruent, but the side lengths are always proportional.

Take for instance, an equilateral triangle has a dimension of 2cm by 2cm by 2cm

The similar triangles could have the following dimensions:

This is so because the triangles are proportional to the equilateral triangle
