Answer:
b = 7
Step-by-step explanation:
Since the triangle is right use the tangent ratio to solve for b
and the exact value
tan30° = 
, thus
tan30° = 
= 
and
= ( cross- multiply )
b = 7

We want to create a linear equation to model the given situation.
A) c(r) = $6.00 + $1.50*r
B) 19 rides.
We know that the carnival charges $6.00 for entry plus $1.50 for each ride.
A) With the given information we can see that if you ride for r rides, then the cost equation will be:
c(r) = $6.00 + $1.50*r
Where c(r) is the cost for going to the carnival and doing r rides.
B) If you have $35.00, then we can solve:
c(r) = $35.00 = $6.00 + $1.50*r
Now we can solve the equation for r.
$35.00 = $6.00 + $1.50*r
$35.00 - $6.00 = $1.50*r
$29.00 = $1.50*r
$29.00/$1.50 = r = 19.33
Rounding to the next whole number we get: r = 19
This means that with $35.00, Dennis could go to 19 rides.

Answer:
450
7,500 + 450
Step-by-step explanation:
Answer: a = 4/3
Step-by-step explanation:
1. a/4 − 5/6= −1/2 convert -1/2 to -3/6
2. a/4 = 5/6 - 3/6 = 2/6 = 1/3
3. a = 4*2/6 = 4*1/3
4. a = 4/3
