An octagon has 8 sides. Each side is given as 2a + 1
Perimeter = 8(2a + 1)
= 16a + 8
Answer: 16a + 8
For any circle with Cartesian equation
,
we have that the centre of the circle is
, and the radius of the circle is
.
So in the case that
,
we essentially have that
.
So the centre of the circle is
, and the radius is
.
B. 4 inches is the answer
V= 50 degrees
This is because the line on which the angle 70 is at adds up to 180 and it we subtract 70 from the straight angle we have 110 degrees that means the other angle on the other side of the 70 is 110 so if we add 110 and 20 we get 130 and since all angles of a triangle add up to 180 we subtract 130 from 180 and get 50
Answer:
yes, he would have enough money
He would need a total of 1.5 gallons to paint the wall .
the cost of 1.5 gallons is $18 dollars.
Andrew has 40. he has enough money
Step-by-step explanation:
total gallon needed to pain four walls = 3/8 x 4 = 1 1/2 gallons
total cost of 1 1/2 gallons = 1 1/2 x $12
to calculate this amount convert 1 1/2 to improper fraction
to convert to improper fraction, take the following steps :
1. Multiply the whole number by the denominator
2. Add the numerator to the answer gotten in the previous step
3. divide the number gotten in the previous step by the denominator
3/2 x $12 = $18
