34 - 6 = 28
28 x 8 = 224
After making the 6 whole sheet of paper cards for her closest friends Aimi will have 28 pieces of paper left.
Since she wants to use 1/8 of a sheet per valentine (think of it as one piece of paper can make 8 valentines) you can do 28 pieces of paper multiplied by 8 which gives you 224 valentines.
Answer:
102
Step-by-step explanation:
Let the unknown measure be x
So all the angles add up to 180
therefore,
13 + 65 + x = 180
78 + x = 180
x = 180 - 78
x = 102

Answer:
hello :
note : 1²+2²+3²+........+n² = n(n+1)(n+2)/6
Step-by-step explanation:
let : S = 1²+2²+3²+......+25²
A = 16²+17²+18²+...+25²
B = 1²+2²+3²+......+15²
S = (1²+2²+3²+....+15²) + (16²+17²+18²+...+25²)
calculate : S for : n = 25
S = 25(26)(27)/6 = 2925
calculate : B for : n = 15
B = 15(16)(17)/6 = 680
so : S = B + A
A = S - B = 2925 - 680 = 2245
