Answer:
x = 4.3
Step-by-step explanation:
x= 4.3
Answer: 15.5
Step-by-step explanation:
(10.5-7)+(4x3)
following PEDAS we do operations in parentheses first
10.5-7=3.5
4x3=12
we now have 3.5+12 as our intermediate expression
and 3.5+12 = 15.5
I believe it is 35!
I hope this helps you, and don't forget to give this answer brainliest if it really helped!
Answer:
314 inches³
Step-by-step explanation:
The area of a cone is πr²h/3. We need to find the height and radius of the cone. The height is 12 inches. radius * 2 = diameter.
Radius * 2 = Diameter
/2 /2
Radius = 1/2* Diameter
Radius = 5 inches
We substitute it in:
3.14 * 5² * 12/3:
3.14*25*4
314 inches³
Basically there are 3 addition properties and they are associative property, identity property, and commutative property.
Commutative property is just changing the order of the addends. Example: 26+19+34+21= 21+34+19+26
Identity Property is just adding a 0 to the number that doesnt change anything. Example: 26+19+34+21 +0 = 100
Associative property is just changing the grouping of the addends. Example: (26+19) + (34+21)
I know these properties may be complicated i know inhate them too haha but i hope i helped :) if you want you can search up the distributive property too but its with multiplication and addition combined and its harder but i think these are the 3 main properties.
Hope this helps!
