Answer:
(not this) 3/4-5+9-2/4+2
Step-by-step explanation:
1 1/3 instead of 3/4 and 2/4
Answer:
1. Rectangle
2. 376.8 cm
3. 379.94 square feet
4. –4 and 4
Step-by-step explanation:
A square is always a rectangle.
If a wheel has a radius of 15 cm, it would travel approximately 376.8 cm per 4 revolutions.
If the diameter of a circular garden is 22 feet, the approximate area of the garden is 379.94 square feet.
The solutions to the equation y2 – 1 = 15 is –4 and 4.
Answer: −6c−j−9
Step-by-step explanation:
Answer:
The value of f(-3) = -3
Step-by-step explanation:
It is given that f(x) = 3(x+2), in order to find f(-3), we have to substitute x = -3 into the function, f(x) :
f(x) = 3(x+2)
f(-3) = 3(-3+2)
= 3(-1)
= -3
interior angle of a regular 18-gon.
It is easier to calculate the exterior angle of a regular polygon of n-sides (n-gon) by the relation
exterior angle = 360/n
For a 18-gon, n=18, so exterior angle = 360/18=20 °
The value of each interior angle is therefore the supplement, or
Interior angle = 180-20=160 degrees.
Naming of a 9-gon
A polygon with 9 vertices is called a nonagon (in English) or enneagon (French ennéagone, but the English version is sometimes used)
You had a good start with the correct answer.
Exterior angle of a 15-gon
The exterior angle of a 15-gon can be calculated using the relation given in the first paragraph, namely
Exterior angle = 360/15=24 degrees
