Answer:
3*10=30.
Step-by-step explanation:
increased by 3% each year for 10 years
increased 30%.
0.31*0.30= .92
SO you would have to first have the surface area of the cube which is 25 for each side so 25 x 6 = 150
Then you find the surface area for the other sides and It is 4 x 5 divided by two for each triangle on the side, so that would be 20 and you multiply then 6.4 x 5 to equal 32 for the rectangle. The last part is the bottom and it is 4 x 5 again which is 20 so then you add them all up but im not sure.
If your number is quite large, like 3 digit or higher than that, then calculate the sum of their digits, if they will be divisible by 3, then the number is divisible, otherwise not.
For example. - "11055"
Here, sum of digits = 1 + 1 + 0 + 5 + 5 = 12
As 12/3 = 4 (Divisible)
In short, This number would be divisible.
Hope this helps!
Total measure of the triangle is 180
So you set the equation equal to 180 and then solve for x using basic calculation
13x=115
X=8,85
