Felix says that 2,000 + 400 + 70 is another way to write 2,407. what is felix’s error

2,000 + 400 + 70 would equal 2,470.

The correct way to write it would be 2,000 + 400 + 7

Felix's error is that he added the numbers incorrectly.

Felix got the answer 2,407 by adding 2,000 + 400 + 7, but the problem states to add 2,000 + 400 + 70. In return, by adding in the correct way like the question have stated you should get 2,470

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
