Question

I need help with these problems from #33 to #40 can someone please help me with them ASAP please and thank you.. can you show step by step please and thank you .. this was due today

Answer 1

#33

$\\ \sf\longmapsto \dfrac{300(300+1)}{2}$

$\\ \sf\longmapsto \dfrac{300(301)}{2}$

$\\ \sf\longmapsto 150(301)=45150$

#34

$\\ \sf\longmapsto \dfrac{500(500+1)}{2}$

$\\ \sf\longmapsto 250(501)$

$\\ \sf\longmapsto 125250$

#35

$\\ \sf\longmapsto \dfrac{675(675+1)}{2}$

$\\ \sf\longmapsto dfrac{675(676)}{2}$

$\\ \sf\longmapsto 675(338)$

$\\ \sf\longmapsto 228150$

#36

$\\ \sf\longmapsto \dfrac{825(825+1)}{2}$

$\\ \sf\longmapsto \dfrac{825(826)}{2}$

$\\ \sf\longmapsto \dfrac{825(413)}{1}$

$\\ \sf\longmapsto 340725$

#37

• n=102/2=51

$\\ \sf\longmapsto n^2$

$\\ \sf\longmapsto 51^2$

$\\ \sf\longmapsto 2621$

#38

• n=49+1/2=50/2=25

$\\ \sf\longmapsto n^2$

$\\ \sf\longmapsto 25^2$

$\\ \sf\longmapsto 625$

#39

• n=999+1/2=1000/2=500

$\\ \sf\longmapsto n^2$

$\\ \sf\longmapsto 500^2$

$\\ \sf\longmapsto 250000$
