Answer:
S7 = 70/3
Step-by-step explanation:
Given:
series: 1/3+4/3+7/3+....
a = 1/3
Find:
S7
Computation
d = a2-a1
d = 4/3 - 1/3
d = 1
⇒ Sn = n/2[2a+(n-1)d]
⇒ S7 = 7/2[2(1/3)+(7-1)1]
⇒ S7 = 7/2[2/3+6]
⇒ S7 = 7/2[20/3]
S7 = 70/3
Answer:
The triangles are similar because all pairs of corresponding angles are congruent.
Step-by-step explanation:
7.2 times 4=28.8-10=18.8
she saves 18.8 dollars per week.
18.8 times 12=225.6
after 12 weeks she has saved 225.6 dollars
225.6 times 0.25=56.4
her grandparents giver her 56.4 dollars
56.4+225.6=282
she has 282 dollars
