The answer is C.

20.39÷6.5=3.1369(rounded)
13.52÷4.3=3.1442(rounded)
22.32÷7.1=3.1437(rounded)

(3.1369+ 3.1442+ 3.1437)÷3=3.1416

I’m really sorry if the answer is incorrect!!

If the mass of a material is 49 grams and the volume of the material is 7 cm^3, what would the density of the material be?

inysia [295]

The equation for density is:
$density = \frac{mass}{volume}$

To help you remember - my teacher told us to remember "We ♡ density," and the heart stands for $\frac{m}{v}$ , or $\frac{mass}{volume}$ . Cheesy, but it works!

Back to the problem:
We know the mass if 49g and the volume is 7 $cm^{3}$ , so plug these values into the equation for density:
$density = \frac{mass}{volume}\\
density = \frac{49\:g}{7\:cm^{3}} \\
density = 7\:g/cm^{3}$

Answer: The density is 7 g/ $cm^{3}$

Find x A. 22√2 B. 22 C. 11√3/3 D. 11√3

mel-nik [20]

Answer

$22\sqrt{2}$

Step-by-step explanation:

First we gave a name to the side that is common for both triangles, can be Y for example.

Using trigonometric functions we can make a relationship between the two angles that we have and the magnitud of the side.

$sin(45)=\frac{11}{Y} \\$ , Because sin(x)= op/hip

$cos(60)=\frac{Y}{x}$ , Because con(x)=ad/hip

Having this equations, we can solve the system and find x

$Y=\frac{11}{sin(45)} \\Y=cos(60)*x$

we equal Y and solve

$\frac{11}{sin(45)}=cos(60)*x\\ x=\frac{11}{sin(45)*cos(60)} \\x=\frac{11}{\frac{\sqrt{2} }{2} *\frac{1}{2} } \\x=\frac{11}{\frac{\sqrt{2} }{4} } \\x=\frac{44}{\sqrt{2} }\\$
