Answer:
well the volume of a sphere is V = 4/3 x pie x r3 so the radius is half of the diameter so that would be 8 not going to show work but the answer is 2144.66
The answer is 750000000000
im not sure im so sorry i tryt o figure out
Answer:
D. x= 28, 2=23; Use corresponding and supplementary angles.
Step-by-step explanation:
The degrees of (5y-4)° and 3y° both (added together) sum up to 180 degrees.
So the equation would be: (5y-4)+3y= 180.
Step 1- Add common variables.
(5y+3y)-4= 180
8y-4= 180
Step 2- Add 4 to both sides.
8y-4= 180
<u> +4 +4</u>
8y= 184
Step 3- Divide both sides by 8.
<u>8y</u>= <u>184</u>
8 8
y= 23
Now that we know what the variable y equals to, we can now solve for x. The equation would be: 3y=(2x+13).
Step 1- Substitute the known variable.
3(23)=2x+13
69= 2x+13
Step 2- Subtract 13 to both sides.
69= 2x+13
<u>-13 -13</u>
56= 2x
Step 3- Divide both sides by 2.
<u>56</u>= <u>2x</u>
2 2
x= 28
Hope this helps! :)
Answer:
they are opposite degrees so we can say that 4x=2y-x
Step-by-step explanation:
5x=2y and we complete 4x+(2y+x)=180. and then 5x+2y=180. put 2y from 5x. 4y=180 y= 45 and x= 18°
