D 10” riser , 7-1/2 treas
Step-by-step explanation:
2/5+2/4 (find common denominator)
The common denominator is 20
2/5 is 8/20 (multiply by 4)
2/4 is 10/20 (multiply by 5)
8/20+10/20 is 18/20
If you simplify 18/20 this would by 9/10 if you divide by 2
so the total is 18/20 or 9/10 simplified
Hope this helps!!!!
Have a nice day :)
4*0.79+2*3.99+12.18+3*4.12 =35.68
including tax it's 35.68+ 8%of 35.68=35.68 +(8*35.68/100)=35.68+2.8544=38.5344$
Double of 50 is 100, so 28*100=2800, now half of the answer is 2800/2=1400
Answer:
1178.25cm^3
Step-by-step explanation:
Volume of a cylinder is given as V = Pi x r^2 xh
PI= 3.142
R = 5cm
H=15cm
So volume = 3.142 x 5cm x 5cm x 15cm
= 1178.25cm^3
