Theres an app called photomath that could easily solve problems like this
9 people would want Red pens, and 27 would want Blue pens. You can solve this by first adding the two numbers together to get 12. Then, you would divide 48 by the 12 you just got to get 3. You can then multiply 3 and 9 by 3 to get how many of each color you need to get.
Answer:
12.1 km
Step-by-step explanation:
350 * 2 = 700
200 * 2 = 400
700 + 400 = 1100
1100 * 11 = 12100
12100 / 1000 = 12.1
12.1 km
Answer: g(f(h)) = pie(200h)^2
Step-by-step explanation:
Answer:
9.74418019cm=h
~ 9.7442
Step-by-step explanation:
volume of a cylinder=πr²h
radius=½of diameter
=½×140cm
=70cm
1l=1000cm³
150l=150l/1l×1000cm³
=150000cm³
150000cm³=π(70cm)²×h
150000cm³=15393.8040cm²h
150000cm³/15393.8040cm²=15393.8040cm²h/15393.8040cm²
150000cm³/15393.8040cm²=h
9.74418019cm=h
