Conditions for side lenghts for triangle:
a<b+c and
b<c+a and
c<a+b
so we check all posibilities:
A) 2+5=7 we can see that one condition is not fulfilled so they can't be side lenghts of triangle
B) 9<14+17
14<9+17
17<14+19
All conditions are fulfilled so they can be side lenghts of triangle
C)7<17+24
17<7+24
24<17+7
All conditions are fulfilled so they can be side lenghts of triangle
D)5<12+13
12<5+13
13<5+12
All conditions are fulfilled so they can be side lenghts of triangle
Answer:
they both = 100
Step-by-step explanation:
p = 3r + 2s
p - 3r = 2s <em>subtract 3r from both sides</em>
(p - 3r)/2 = s <em>divide both sides by 2</em>
Answer: (p - 3r)/2
Volume of the 1st package : 8.5x11x2 =187 in³
Volume of the 2nd package = 17.5x12x10 = 2,100 in³
Number of packages that fit = V₂/V₁ = 2100/187 = 11.23 Packages
To estimate the answer of 872*3 we know that 872 is only 28 away from 900 so we'll round 872 up to 900. Then we can take 900*3 which is 2,700. So we now know that 872*3 is roughly 2,700.
Hope this helps!=)
