Answer:
(a) the size of each exterior angle 360/10=36
(b) the number of sides of the polygon. 10
Step-by-step explanation:
Each interior angle of a regular polygon is 4 times each exterior angle
∴sum of interior angles: (n-2)*180=4*360
n-2=8
n=10
(a) the size of each exterior angle 360/10=36
(b) the number of sides of the polygon. 10
Answer:
723.53 m^2
Step-by-step explanation:
The area is the product of the width and length. Each foot is 0.3048 meters, so the area in square meters is ...
(59 ft·0.3048 m/ft)·(132 ft·0.3048 m/ft) ≈ 723.53 m^2

Answer:
The system of equations are;
4.75t + 7.50b = 790
t = 2b
where t is the number of tacos and b is the number of burritos
Step-by-step explanation:
In this question, we are concerned with writing the system of equations that could help us determine the number of tacos and burritos sold.
Firstly, we start with defining variables. Let the number of tacos sold be t and the number of burritos sold be b
*there we twice as many burritos as tacos sold. What this simply means is that the number of tacos sold is twice the number of tacos.
Mathematically that could be written as ;
t = 2b ••••••••••(i)
Now, let’s work with the revenue;
Each taco is sold at $4.75 and he sold a total of t tacos. The revenue realized from tacos sold is thus $4.75 * t = $4.75t
The money realized from selling b burritos at $7.50 each would be $7.50 * b = $7.50b
The addition of both of these will give the total revenue of $790
Thus, we have;
4.75t + 7.50b = 790 ••••••• (ii)
