Answer:
Step-by-step explanation:
2004 - 1995 = 9 years
793 - 54 = 739 new sites
739 / 9 = 82.1111111111
approx 82 websites per year change.. ( delta is change )
Answer:
B. sin35/9=sin40/b
Step-by-step explanation:
The law of sines tells you ...
sin(A)/a = sin(B)/b
Filling in the given values, you get ...
sin(35°)/9 = sin(40°)/b
Answer:
13.) 314.2 in²
15.) 181.5 ft²
Step-by-step explanation:
The area of a circle is found using the equation:
A = πr²
In this equation, "π" represents the number pi (3.14....) and "r" represents the radius (half the diameter).
For 13.), you have been given the radius. Thus, you can substitute it into the equation and solve for "A".
A = πr²
A = π(10)²
A = π x (100)
A = 314.2 in²
For 15.), you have been given the diameter. To find the radius, you need to divide this value by 2. Once you find the radius, you can plug it into the equation and simplify like above.
diameter = 15.2 ft
radius = 7.6 ft
A = πr²
A = π(7.6)²
A = π x (57.76)
A = 181.5 ft²
Answer:
36
Step-by-step explanation:
Substituting the value of b into the expression (not equation!), we get:
6(2*5-4)
Then, simplifying the expression we get:
6(10-4)
6(6)
36
Hope this helps!
