Answer:
m = 72.9 grams
Step-by-step explanation:
Given that,
The density of a cube, d = 2.7 g/mL
Side of the cube, l = 3 cm
The volume of the cube is :
![V=l^3\\\\V=(3)^3\ cm^3\\\\V=27\ cm^3](https://tex.z-dn.net/?f=V%3Dl%5E3%5C%5C%5C%5CV%3D%283%29%5E3%5C%20cm%5E3%5C%5C%5C%5CV%3D27%5C%20cm%5E3)
Since, 1 mL = 1 cm³
Mass per unit volume is equal to the density of an object.
![m=d\times V\\\\m=2.7\ g/mL\times 27\ mL\\\\m=72.9\ g](https://tex.z-dn.net/?f=m%3Dd%5Ctimes%20V%5C%5C%5C%5Cm%3D2.7%5C%20g%2FmL%5Ctimes%2027%5C%20mL%5C%5C%5C%5Cm%3D72.9%5C%20g)
So, the mass of the cube is 72.9 grams.
Move 3 to the left and go 5 up and stop at 4
Hope this helps!!!!!!
3.4+0.5y +1.1=-4.5
3.4+1.1+0.5y= -4.5
4.5+0.5y=-4.5
move 4.5 to the other side
sign changes from +4.5 to -4.5
4.5-4.5+0.5y= -4.5-4.5
0.5y= -4.5-4.5
0.5y=-9
divide both sides by 0.5
0.5y/0.5= -9/0.5
Answer: y= -18
637 is the answer because our value is 980 we all know the unknown value with x for the step above 980 and 100% and 65% is the result in a pair of a simple equations
Answer:
B) 47 units²
Step-by-step explanation:
It can be done by finding the area of the black, but it will be much easier to find the area of the white and subtract.
Total area of the grid equals 10x8=80
There are two rectangles at the bottom. 6+8=14
There are 4 triangles that each equal 4.5. 4.5*4=18
There is 1 small triangle at the top that equals 1.
80-14-18-1=47
