Answer:
8 and 9
Step-by-step explanation:
<u>Since 77 is between 64= 8² and 81= 9²</u>
- √64 < √77 < √81
- 8 < √77 < 9
Answer:
1094
Step-by-step explanation:
The sum of terms of a geometric series is given by ...
Sn = a1·(r^n -1)/(r -1)
You want the sum for ...
a1 = 2, r = -3, n = 7
Filling in the numbers, we get ...
S7 = 2·((-3)^7 -1)/(-3-1) = 2(-2188)/(-4)
S7 = 1094
Answer:
RS = 19
Step-by-step explanation:
Given a segment joining the midpoints of 2 sides of a triangle then it is half the length of the third side, that is
- 5x + 44 = (18 + 4x) ( multiply both sides by 2 to clear the fraction )
- 10x + 88 = 18 + 4x ( add 10x to both sides )
88 = 18 + 14x ( subtract 18 from both sides )
70 = 14x ( divide both sides by 14 )
5 = x
Then
RS = - 5x + 44 = - 5(5) + 44 = - 25 + 44 = 19
