First for 7 we need to find out how many ninths are in a third and there are 3/9 in a third so now we multiply 3/9 by 2 which is 6/9 now we subtract 7/9-6/9 which is 1/9 so 1/9 is left. (Iff I'm wrong sorry I did this is like a minute.)
Answer:
b) 2 hours and 35 minutes
Answer:
Solution given:
b=9 base side of isosceles triangle
a=
Answer:
0.0082
Step-by-step explanation:
Volume of the mug: PI r^2 (h)
R ====> Radius
H ====> Height
Radius of mug is:
7 / 2 * 1 / 2 b
===> 3.5cm^3
volume of mug:
===> 3.5^2 * PI r^2 * 9
===> 346 cm^3
20 ice cubes ===> 20 cm^3 is needed:
substract:
20 cm^3 - 346
===> 326 cm^3
The volume of the mug is the area of its base; The mug's height, or πr^2 h. This is; 3.5 cm * 3.5 cm. · 9 · π, or 346.2 cm3. The volume of each ice cube is 1 cubic centimeter, so 20 of them will occupy 20 cm^3.
Answer: This leaves 326 cm^3 for the coffee.
Hope that helps!!!! : )
