Answer:
- commutative property
- distributive property
Step-by-step explanation:
The expression
4.7x + 10.4 + 15.3x − 8.4x + 15.6
can be simplified in a few stages. First of all, we use the commutative property of addition to swap terms 2 and 3.
4.7x +15.3x +10.4 -8.4x +15.6
Next, we use the distributive property to factor x from the first two terms.
(4.7 +15.3)x +10.4 -8.4x +15.6
Now we perform addition.
20x +10.4 -8.4x +15.6 . . . . . . . . equivalent expression
To find the volume of a dome, you would have to find the volume of the sphere, theoretically, and then divide it by two. To calculate the volume, we would use the formula 4/3
. The radius (r) in this case is half of the diameter which is 14. 4 x 3.14 (pi) = 12.56. 12.56 x 14 x 14 x 14 (2744) = 34464.64. If we divide this number by 3, we get 11488.2133. If we divide this by 2 (to get the dome), we get 5744.10656. Which would be 5744.1 rounded to the nearest tenth.
Answer:
about 35%
Step-by-step explanation:
85/245 x 100 = 34.7 round up = about 35%
It could be 10.11 10.12 10.13 10.14
as long as the number next to the one is less than five it will become 10.1
