Answer:

As demand rises, the price of the product decreases

As demand decreases, costs generally increase

The average rate of change describes how much a quantity changes as price increases.

Step-by-step explanation:

As we know that

The price and the supply has a direct relationship between each other according to the law of supply that means if the price of the product increases the supply of the product is also increases and vice versa

And, the price and the demand had an inverse relationship between each other according to the law  demand that means if the price of the product increases the demand of the product is decreased and vice versa  

Plus if there is an increase in prices so how much quantity changes are computed by considering the average rate of change

Therefore, these above three statements are true.

A box in the shape of a cube has a volume of 64 cube inches. What is the length of a side of the box
Naily [24]

The volume of a cube can be expressed as

Let V = volume

Let a = side length

V = a^3

We need to solve the formula to isolate the variable a. First, we must cube root each side.

∛(V) = a. With our new formula, we plug in 64 cube inches into V.

∛(64) = a.

4 = a.

The length of one side on our cube is 4 inches.

Answer:

The percentage increase in bird population in the second years is 4%  .

Step-by-step explanation:

Given as :

During two years, the population of birds of an island became 7 times more than before.

The the percentage increase in first year = = r_1 =40%

Let The percentage increase in second year =  r_2 = r%

So, According to question

The initial population of bird = x

The increase population of bird =7 times before = 7 x

Now,

The increase population of bird = initial population of bird × (1+ \dfrac{r_1}{100}) ×  (1+ \dfrac{r_2}{100})

Or, 7 x = x × (1+ \dfrac{40}{100}) ×  (1+ \dfrac{r}{100})

Or, \dfrac{7 x}{x} = 1.4 ×  (1+ \dfrac{r}{100})

Or, 7 = 1.4 ×  (1+ \dfrac{r}{100})

Or, \dfrac{7 }{1.4} = (1+ \dfrac{r}{100})

Or, 5 = (1+ \dfrac{r}{100})

Or, (1+ \dfrac{r}{100}) = 5

Or, \dfrac{r}{100} = 5 - 1

Or,  \dfrac{r}{100} = 4

∴ r = 4 × 100

I.e r = 400

so, The percentage increase = r% = 4

Hence The percentage increase in bird population in the second years is 4%  . Answer

mixer [17]
Answer: x=32

Exclamation:

-3x\4+25=1/8x-3

-3/4x+25=x/8-3

-6x+200=x-24

200=x-24+6x

200=7x-24

200+24=7x

224=7x
