Let's start by evaluating the parenthesis on the right. Because of the order of operations (PEMDAS - parenthesis, exponents, multiplication/division, addition/subtraction), we divide 3 by 1/8 first. This is equal to multiplying 3 * 8, or 24. Next, we subtract 5 from 24. This is equal to 19.
Next, we subtract 19 from 3/4. -18 1/4 We complete this problem by adding (1/2)^2, or 1/4. This is: -18 1/4 + 1/4 = -18, so -18 is the answer.
Answer:
233.3 cubic units
Step-by-step explanation:
Volume of a pyramid
× base area × height
The volume of the pyramid
= 233.3 cubic units (rounded to the nearest tenth)
Ok so
first one is 1
2nd is 2
3rd is 4
so
an=a1(r^(n-1))
a1=first term
r=common ratio
n=which term
frst term is 1
common ratio is 2
n=64
a64=1(2^(64-1))
a64=2^63
B would be the answer
The solution to this one is 10
