Answer:

c is correct.

Step-by-step explanation:

First we simplify the expressions of the parties, and when we get to the two fractions, we multiply the cross, and the answer is obtained.

$\frac{89}{2725} > \frac{1989}{2500000} \\ \\ \\ 89 \times 2500000 > 1989 \times 2725 \\ \\ 222500000 > 5420025$

It should be noted that with a few quick calculations the correct option was reached.

Describe the dimensions of two different prisms that each have a volume of 2400 cubic centimeters using work

kirza4 [7]

Answer:

Step-by-step explanation:

Alright, lets get started.

We have given the volume of a prism that is 2400 cubic centimeters.

we have not given which type of prism it is, so we are taking it as a rectangular prism.

The formula of volume of rectangular prism is :

$Volume = l*w*h$

Where l is length of base

w is width of base

h is height of prism

So, $2400=l*w*h$

So, if we factor 2400 in two different manners, we could have two different dimensions of this prism having same volume that is 2400.

So, our first factor would be :

$2400=20*20*6$

Means the prism has base of 20 and 20 centimeters and height of 6 centimeters.

Our second factor would be :

$2400=40*30*2$

Means the prism has base of lenght 40 and width 30 and its height is 2 centimeters.

Hence we have two dimensions of prism, 20 20 6 and another one is 40 30 2. : Answer

Hope it will help :)

Ok, 20 points for this one

arsen [322]

Answer:

Step-by-step explanation:

2 angles are added to result in = 180°

therefore

180 = 97 - 3x + 69 + 5x

180 = 166 + 2x

2x = 180 - 166

2x = 14

x = 14 ÷ 2

The value of x = 7

Finding an Indefinite Integral dx/x(lnx^2)^3

Y_Kistochka [10]

Step-by-step explanation:

Firstly, we'll try to simplify the integrand. By hint 1, we see that:

$\ln(x^2) = 2\ln(x)$

Simplifying the integrand gives us:

$\frac{1}{8}\left(\frac{1}{x(\ln(x))^3}\right)$

Next, by hint 2, we observe that:

$\frac{d}{dx}\left(\ln(x)\right) = \frac{1}{x}$

So this tells us to make the substitution: $u = \ln(x)$

Doing so gives us:

$\int \frac{dx}{x(ln(x^2))^3} = \int \frac{du}{8u^3}$ , which should be trivial.
