Answer:
114.3cm^3
Step-by-step explanation:
Square Pyramid Formulas derived in terms of side length a and height h: Volume of a square pyramid
V = (1/3)(Base area of a square)(Height of the square pyramid).
V = (1/3)area
hight
Area of the square
A = 7 x 7
A = 49
V = (1/3)49 x 7
V = (1/3)343
V = 114.(a repeating term)3
since we rounded
V = 114.3cm^3
Answer:
Option b is correct 175
Step-by-step explanation:
n = 7
k = 6
3k -2 ------1
put k = 6 in above eq. for finding first term
a1 = 3(6) - 2 = 18 - 2 = 16
put k = 7 in above eq. for finding first term
a2 = 3(7) - 2 = 21 - 2 = 19
a3 = 3 (8) - 2 = 24 - 2 = 22
16, 19 , 22, ... //Arithmetic series formation
a1 = 16 , a2 = 19
d = a2 - a1 = 19 - 16 = 3 //Difference of first two terms
Using sum forumula for arithmetic series
sum = 
= 
= 
=
=
= 7 * 25
= 175
I am so sorry for giving you the wrong answer at first.
Here's the processs
1x=-0.5555
Move the decimal point in the repeating decimal one space forward
10x=-5.55555
Then subtract
10x=5.5555
x=-0.5555= 9x=-5
Divide both sides by 9
9x=-5
9x/9=-5/9
-5/9 is your final answer!
Hope this helps!
