Answer:
Answer C
Step-by-step explanation:
If the polygon has n sides, then the number of diagonals the polygon has is
(n - 3)*n/2
So for a seven sided figure the number of diagonals would be
(7 - 3)(7)/2 = 4*7/2 = 28/2 = 14
Answer:
16:1
Step-by-step explanation:
The ratio of the surface areas of the similar solids is the square of the lengths.
(4:1)²
4²:1²
⇒ 16:1

Answer:
241
Step-by-step explanation:
Simplify the following:
2^8 - 10 - 15/3
The gcd of -15 and 3 is 3, so (-15)/3 = (3 (-5))/(3×1) = 3/3×-5 = -5:
2^8 - 10 + -5
2^8 = (2^4)^2 = ((2^2)^2)^2:
((2^2)^2)^2 - 10 - 5
2^2 = 4:
(4^2)^2 - 10 - 5
4^2 = 16:
16^2 - 10 - 5

Answer: 241
Answer:
here
Step-by-step explanation:
Given that the height(h) of the plant to the nearest 1/4 of an inch is 3/4 inches = 0.75 inches.
it is obvious that the height will lie within the range
Thus,
a. The largest actual height could be 0.875 inches, while
b. The smallest actual height could be 0.625 inches
c. The percentage error is given by the formula
if we take the lowest value, for instance, as the exact, i.e. 0.625 inches, then % error = [(0.75-0.625)/0.75]*100% = 16.7%
