Answer:
3 hours times 6.80= 20.40
2 hours times 6.20= 12.40
20.40 + 12.40 = 32.80
32.80 ÷ the 5 hours= $6.56 per hour average
Solution:
Let number of upgrade options = p
Let total number of distinct variations in which 256 new homes is available = k
So, p × p× p.....k times = 256
⇒
256= 2 × 2 ×2 ×2 ×2 ×2 ×2 ×2= 
256= 4 ×4 ×4 × 4=
So,Either, number of upgrade options = 2 ,
Or , Number of upgrade options = 4

Answer:

Step-by-step explanation:
The angle measure of a straight line is (180) degrees As given in the picture, line (AC) is a straight line, thus its angle measure is (180) degrees. Angles (ABD) and (DBC) make up line (AC). Therefore, one can conclude that the sum of angles (ABD) and (DBC) is (180) degrees. Form an equation, simplify and use inverse operations to solve for the unknown parameter (q).

Substitute for the angle measures,

Simplify,

Inverse operations,

Answer: A≈226.98 ft²
Step-by-step explanation:
The formula for area of a circle is A=πr². The formula doesn't include diameter , but we can certainly find the radius from the diameter.
d=2r
17=2r
r=17/2=8.5 ft
Now that we have the radius, we can plug it in to area formula.
A=πr²
A=π(8.5ft)²
A=π72.25ft²
A≈226.98 ft²
