Answer:
My calculation might be wrong, so take A.
Step-by-step explanation:
Volume= Volume of hemisphere+volume of cone
Volume=
×π×r³ + πr²
Volume=
×
×4×4×4 +
×4×4×
Volume= 134.095 + 410.6
Volume= 544.695
I believe it is C. Multiply 640 by 7.5. You should get 4800
2/3 girls that's mean there is 1/3 boys.
If there are 18 girls that mean half this number is the boys which is 9.
Therefore, total number is 27.
The slope is
1. Find ordered pairs ( 1 , -4 ) ( 3, 3)
The formula is
M= y2 - y1
_____
X2- X1
2. Replace the numbers
M = 3 - 4.
———
1-3
Subtract
3. You get -1/-2
4. Divide you get 0.5
( but if you need rise and run use -1/-2) rise top run bottom
Slope is 0.5 I think
Hope this helps here a picture of my lesson.
