0.4L = 400ml
Each student effectively adds 10ml of water so 22 students are adding 10ml of water each. Therefore, 22 x 10 = 220ml total in all the containers added by all 22 students
Water left = 400 - 220 = 180
The answer is B.
2x+x-2=-2-x-1
3x-2=-3-x
4x=-1
x=-0.25
Answer:
they will both weigh the same at week 10
Step-by-step explanation:
both will weigh 225 at week 10
Step-by-step explanation:
Sum of interior angles in a polygon = 180°(n - 2).
Size of interior angle in a regular polygon
= 180° - 360°/n
= 180° - 360°/12
= 180° - 30°
= 150°.
Answer:
B
Step-by-step explanation:
When it's parallel that means it has the same slope. The slope of this equation is 1/2 therefore the answer is B
