The difference between masses of both cones is: 838 grams

Step-by-step explanation:

As both cones have same height and radius. Both will have same volume

Here

r=4 cm

h= 10 cm

The volume is given by:

$V=\frac{1}{3}\pi r^2h$

Putting values

$V=\frac{1}{3}*\frac{22}{7}*(4)^2*10\\V=\frac{22}{21}*16*10\\V=167.62\ cm^3$

Mass of Steel Cone:

$M_s=Density\ of\ steel*Volume\\=7.75*167.62\\=1299.055\ grams$

Mass of Granite Cone:

$M_g=Density\ of\ granite*Volume\\=2.75*167.62\\=460.955\ grams$

Difference between masses of both cones

$D = M_s-M_g\\=1299.055-460.955\\=838.1\ grams$

Rounding off to nearest gram: 838 grams

The difference between masses of both cones is: 838 grams

If xr-st=r, which expression represents x

Alexus [3.1K]

Answer:

To get an expression relating to x you need to have x alone on one side of your equation. ie x =

Try this:

rx - st = r

remove st from the rx side

rx = r + st

now divide by r

x = (r + st)/r

You now have your expression relating to x

To the nearest tenth, find the approximate distance between points A and C. Graph with coordinates A negative 4, negative 4. B n

Musya8 [376]

We have that
A(-4,-4) B(-2,5) C(2,1) D(2,-4)

step 1
find the distance AC with the formula
d=√[(y2-y1)²+(x2-x1)²]------> dAC=√[(1+4)²+(2+4)²]----> dAC=√61 units
dAC=√61-----> dAC=7.8 units

the answer is
the option
<span>B. 7.8 units</span>

X=? Y=6<br> 75 degree angle at (0,0)<br> What is X?

choli [55]

Answer:

$X=12-6\sqrt{3}=1.6077$

Step-by-step explanation:

Given that $Y=6$

$\tan(75)=\frac{Y}{X} \\X=\frac{Y}{\tan(75)}=Y\cot75=6\cot75 \\\\Calculate \ \cot(75)\\\tan(75)=\tan(45+30)=\frac{\tan45+\tan30}{1-\tan45 \cdot \tan30} =\frac{1+\frac{1}{\sqrt{3} } }{1-\frac{1}{\sqrt{3} } } \\\tan75=\frac{\sqrt{3}+1 }{\sqrt{3}-1 } =2+\sqrt{3} \\\cot75=\frac{1}{2+\sqrt{3} } =\frac{2-\sqrt{3} }{2^2-3} =2-\sqrt{3} \\\\Hence\\X=6\cot75=6 \cdot(2-\sqrt{3})\\X=12-6\sqrt{3} \approx1.6077$
