Density" of the given granite block is 2.7g/cm

.

Explanation:

Density of an object is defined as the mass occupied per unit volume. “Density” is represented by “ρ”. Mathematically, \rho=\frac{m}{v}ρ=

v

m

where, “m" mass of an object and "v" is volume of an object.

Given that,

Dimensions of the block are 20 cm, 5 cm and 10 cm.

\text { Volume of the block is } l \times b \times h Volume of the block is l×b×h

\text { Volume of the block is } 20 \times 5 \times 10 Volume of the block is 20×5×10

\text { Volume of the block is } 1000 \mathrm{cm}^{3} \text { . } Volume of the block is 1000cm

3

.

Mass of the block is 2700 g.

Substitute the given values in \rho=\frac{m}{v}ρ=

v

m

to find density of a block.

\rho=\frac{2700}{1000}ρ=

1000

2700

\rho=2.7 \mathrm{g} / \mathrm{cm}^{3}ρ=2.7g/cm

\text { "Density" of the given granite block is } 2.7 \mathrm{g} / \mathrm{cm}^{3} "Density" of the given granite block is 2.7g/cm

Answer:

P(t) = 5.24(1.030)^t

Step-by-step explanation:

The model for P(t) , the population of the town, t years after 1985, best fits the data is option C. P(t) = 5.35 (1.029)^t.

Population growth is defined as the increase in the number of people which is calculated using population growth rate.

Population growth is an exponential function.

So, the function will be of the form,

P(t) = a (b)^t

Initial population is the population in 1985.

P(0) = a (b)⁰ = 5.35

⇒ a × 1 = 5.35  (Since any number raised to 0 is 1)

⇒ a = 5.35

Population in 1990, that is after 5 years is,

P(5) = a (b)⁵ = 6.01

⇒ 5.35 (b)⁵ = 6.01

⇒ (b)⁵ = 1.123

⇒ b = 1.024

So the function which best models is P(t) = 5.35 (1.029)^t.

Hence the function is C. P(t) = 5.35 (1.029)^t.

Answer:

3x^{2}+12x-12x-48

3x^{2}-48

Step-by-step explanation:

I hope this answer has helped you

The given factor (3x – 12)(x + 4) is not equivalent to the 3(x2 – 8x + 16) hence, correct option is (A).

An algebraic factor is the multiplication of two algebraic terms.

That term could be in form of summation multiplication or in subtraction.

The root of the quadratic equation formed by the algebraic factor is always real.

If we divide algebraic factor by a factor which is available inside then the remainder after the division will be zero.

Given that equation

(3x – 12)(x + 4)

⇒ 3x² + 12x - 12x - 48

⇒ 3x² - 48.

Now by option cross-checking

In option (A)

3(x² – 8x + 16)

⇒  3x² - 24x + 48 which is not equal to the (3x – 12)(x + 4).

Hence correct option will be 3x² - 24x + 48.

Answer:

i personally would much rather have $20 off, because as the price goes up the less money you get off of the total price. but with $20 off, youre automatically getting $20 off. if you were to get %20 off of something that is $50, youd only get about $10 off, but if you used the $20 off coupon, you would get $20. which would be much better. so instead of partially getting some of it off, you can get a much larger amount off
