Answer:
<u>Kathy drove the first 9 hours of the trip and Brian drove the last 3 hours.</u>
Step-by-step explanation:
Let's review the information given to us to answer the question correctly:
Total distance of the trip = 750 miles
Time of the trip = 12 hours
Speed of Kathy = 65 mph
Speed of Brian = 55 mph
2. For what length of the time did Kathy and Brian drive?
Let's solve the problem, this way:
x = Time in hours Kathy drove
12 - x = Time in hours Brian drove
Now, let's write our equation to solve for x:
65x + 55 (12 - x) = 750
65x + 660 - 55x = 750
10x = 750 - 660
10x = 90
x = 90/10
x = 9 ⇒ 12 - x = 3
<u>Kathy drove the first 9 hours of the trip and Brian drove the last 3 hours.</u>
The price after the discount was $45.
When the sporting goods store bought the snowboard and marked it up by 25%, the price became:
<em>= Original cost x ( 1 + markup percentage)</em>
= 120 x ( 1 + 25%)
= 120 x 1.25
= $150
The snowboard was then discounted by 70%, the new price becomes:
<em>= Current price x ( 1 - discount rate)</em>
= 150 x ( 1 - 70%)
= 150 x 30%
= $45
In conclusion, the price after the discount was $45.

It’s 19 so the answer would be B
Step-by-step explanation:
y = a(b^x)
a = initial value
If b > 0 and b < 1, then 1 - b is the decay factor.
If b > 1, then b is the growth factor.
what function has a growth factor of 3
Function 3
what function has an initial value of 2
Function 2
what function has an initial value of 0.2
Function 4 since 1/5 = 0.2
what function has an initial value of 1
Function 3
what function has a decay factor of 0.2
None. In Function 2, the decay factor is 1 - 1/5 = 0.8, not 0.2.
what functions are increasing across real numbers?
Functions 3, 4
what functions are decreasing across all real numbers?
Functions 1, 2
A squared + B squared = C squared
57 squared + 76 squared =
(Distance between Southville and Westfield) squared
square root of (3249 + 5776) = Distance between Southville and Westfield
square root of 9025 = Distance between Southville and Westfield
Distance between Southville and Westfield = 95 miles
Hope this helps! God bless :-)
