We know that the diameter of the inner circle (d) and the side of a regular octagon (s) are tied by the formula:
d = (1 +√2) × s
The inverse formula is:
s = d / <span>(1 +√2)
Plugging in numbers:
s = 7 (1 + </span>√2)
= 2.9 ft
Therefore the correct answer is A) <span>2.9 feet</span>
Answer:
30 sweets
Step-by-step explanation:
From the above question
The ratio is given as:
Karan : Preeti
2:3
The sum of the proportion = 2 + 3 = 5
Total number of sweets = 50 sweets
The number of sweets Preeti will get is calculated as:
3/5 × 50 sweets
= 30 Sweets
Therefore, the number of sweets Preeti will get is 30 sweets
Answer:
4
Step-by-step explanation:
Divide 28 by 4 to get 7
Answer:
28 units³
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = Al ( A is the area of end face and l is the length )
Here A = 
and l = 
, thus
V = × ( cancel 21 and 3 by 3 and 2 and 8 by 2 )
= 
× 
= 7 × 4 = 28 units³
Answer:
1. 8x2 - 7x + 4x3 - 2-3x2 + 9x - 4 = 16+2x
Step-by-step explanation:
1. Multiply all the multiplication problems (should look like this --> 16-7x+12-2-6+9x-4)
2. Calculate the sum or difference (should end up looking like this --> 16-7x+9x) and then into this (16 +2x)
Bringing us to the answer → <u>16 + 2x!</u>
