Answer:
A=πr2=π·212≈1385.44236cm²
Answer:
The cross multiplication would be 10(350) = 22(x).
Step-by-step explanation:
We would first convert meters to centimeters. There are 100 cm in a meter; this means 3.5 m = 3.5(100) = 350 cm.
The ratio of the height to base of the model is 10/22. The ratio of the playhouse would then be x/350. This gives us
10/22 = x/350
Cross multiplying, we would have 10(350) = 22(x).
Answer:
n=14/5
Step-by-step explanation:
4n+n-16=-2
We move all terms to the left:
4n+n-16-(-2)=0
We add all the numbers together, and all the variables
5n-14=0
We move all terms containing n to the left, all other terms to the right
5n=14
n=14/5
