Step-by-step explanation:

$\mathrm{Remove\:parentheses}:\quad \left(a\right)=a$

$=3x^2+2x-5x-7$

$\mathrm{Add\:similar\:elements:}\:2x-5x=-3x$

Keenan wants to make a paperweight at pottery class. He designs a pyramid-like model with a base area of 808080 square centimete

slamgirl [31]

Answer:

<h2>The weight of Keenan's paperweight is 3.33 N.</h2>

Step-by-step explanation:

Givens

The base area is 80 square centimeters.
The height of the pyramid is 7.5 centimeters.
The density of the pyramid is 1.7 grams per cubic centimeters.

First, we find the volume of the figure.

$V=\frac{1}{3} (B \times h)$

Where $B=80cm^{2}$ and $h=7.5 cm$ .

Replacing values, we have

$V=\frac{1}{3}(80)(7.5)=200cm^{3}$

The density is defined as

$\rho=\frac{m}{V}$

Where we need to find the mass $m$ , we already know that $\rho=1.7 \ gr/cm^{3}$ and $V=200cm^{3}$ . Replacing these values, and solving for $m$

$1.7=\frac{m}{200}\\ m=1.7(200)=340 \ gr$

Then, we use the weight definition, which is

$W=mg$

Where $m=340 \ gr=0.34 \ kg$ and $g=9.81 m/sec^{2}$ . Replacing these values, we have

$W=0.34(9.81)\\W=3.33 N$

Therefore, the weight of Keenan's paperweight is 3.33 N.

I dont know how to do this will you please help me 118=6x+4

Dominik [7]

6x + 4 = 118

= 6x + 4 - 4 = 118 - 4 ( subtracting both sides by 4)

= 6x = 114

= 6x/6 = 114/6 ( dividing by 6 on both sides )

= x = 19

Cone A has a diameter of 12 meters and a slant height of 9 meters. The linear dimensions of cone B are 5 times the linear dimens

Karolina [17]

Answer:

Cone volume formula

To calculate its volume you need to multiply the base area (area of a circle: π * r²) by height and by 1/3: volume = (1/3) * π * r² * h
