If a company makes two discounts with one being made first and then another, the equivalent discount is 37%.

<h3>What was the equivalent discount?</h3>

Assume that the price of a good in the company was $10.

The initial discount of 30% takes the price to:

= 10 x ( 1  - 30%)

= $7

Then there is a 10% discount:

= 7 x (1 - 10%)

= $6.30

The equivalent discount is:

= (10 - 6.3) / 10

= 37%

Describe the function over each part of its domain. State whether it is constant, increasing, or decreasing, and state the slope
Amanda [17]

The attached image completes the question.

Answer:

- The part (0, 12000) is constant and the slope is zero

- The part (12000, 38000) is decreasing and slope is negative 0.26.

Step-by-step explanation:

Checking the given graph, we see that

For x = 0  to x = 12,000, the values of y are unchanged. For this, we say it is constant.

The slope here is: 0.85 - 0.85 = 0

For x = 12,000  to x = 38,000, the values of y are decreasing. For this, we say it is negative.

The slope here is: 0.59 - 0.85 = -0.26.

How can I find all the angles??

a square has 4 angles and they’re all 90° and a circle is 360°. now if you add all the 4 90° it all comes out to 360° right? rig
OLga [1]
<h2>The above state tells only about the sum of their angle not about their areas. You are right there sum of angles is same but their areas are different. Let's take another example, rectangle also have sum of angles equal to 90 ° but it's not that rectangle is equal to circle. Square and Rectangle are equal because their areas are same.</h2>

Help me with my math pls :)

Answer:

4(x-8)=-32+4: x=1

2(x-2)=-3-2x: x1/4

3+5x=5(x+2)-7: x=0

8x+38=-3(-6-4x) x=5

Step-by-step explanation:

4(x-8)=-32+4

add subtract the numbers

-32+4=-28

4(x-8)=-28

Divide both sides by 4

\frac{4(x-8)}{4}=\frac{-28}{4}

Simplify

x-8=-7

Add 8 on both sides

x+8-8=-7+8

Simplify

x=1

2(x-2)=-3-2x

  • Expand 2(x-2)
  • apply distributive law: a(b-c)=ab-ac

a=2 b=x c=2

=2x-2·2

  • multiply the numbers

2·2=4

=2x-4

2x-4=-3x-2

  • Add 4 to both sides

2x-4+4=-3-2x+4

  • simplify

2x=-2x+1

  • Add 2x on both sides

2x+2x=2x+1+2x

  • Simplify

4x=1

  • Divide by 4 on both sides

4x÷4=1÷4

  • Simplify

x=1/4

3+5x=5(x+2)-7

<em> We move all terms to the left: </em>

<em> 3+5x-(5(x+2)-7)=0 </em>

<em> We calculate terms in parentheses: -(5(x+2)-7), so: </em>

<em> 5(x+2)-7 </em>

<em> We multiply parentheses </em>

<em>5x+10-7 </em>

<em> We add all the numbers together, and all the variables </em>

<em> 5x+3 </em>

<em> Back to the equation: </em>

<em> -(5x+3) </em>

<em>  We get rid of parentheses </em>

<em> 5x-5x-3+3=0 </em>

<em> We add all the numbers together, and all the variables </em>

<em> =0 </em>

<em> x=0/1 </em>

<em> x=0</em>

8x+38=-3(-6-4x)

Simplifying

8x + 38 = -3(-6 + -4x)

Reorder the terms:

38 + 8x = -3(-6 + -4x)

38 + 8x = (-6 * -3 + -4x * -3)

38 + 8x = (18 + 12x)

Solving

38 + 8x = 18 + 12x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-12x' to each side of the equation.

38 + 8x + -12x = 18 + 12x + -12x

Combine like terms: 8x + -12x = -4x

38 + -4x = 18 + 12x + -12x

Combine like terms: 12x + -12x = 0

38 + -4x = 18 + 0

38 + -4x = 18  

Add '-38' to each side of the equation.

38 + -38 + -4x = 18 + -38

Combine like terms: 38 + -38 = 0

0 + -4x = 18 + -38

-4x = 18 + -38

Combine like terms: 18 + -38 = -20

-4x = -20

Divide each side by '-4'.

x = 5

Simplifying

x = 5

Hope this helps

The selling price of an apartment dropped from 250,000 to 225,000. By What percent did the price drop?
ch4aika [34]

Answer:

10%

Step-by-step explanation:

The percentage decrease in price = \frac{decrease amount}{original amount} x 100%

Original amount = 250,000

New amount = 225,000

Decrease in amount = 250,000 - 225,000

                        = 25,000

So that;

Percentage decrease in price = \frac{25000}{250000} x 100%

                                           = 0.1 x 100%

Percentage decrease in price = 10%

The price of the apartment dropped by 10% of its original price.
