the amount of time of the two trips is a proportional relationship
<h3>What is proportional relationship?</h3>
mathematical expressions are said to be proportional if there unit rate are equal. this means that the expressions will give similar results when similar values are substituted into the equation.
<u>solution:</u>
Driving 7 hrs within 385 miles represents a unit rate of 385 / 7 = 55 miles per hour or 55 mph
while 3 hrs in 165 miles represents a unit rate of 165 / 3 = 55 mph
since both situations gave similar speed in miles per hour they are said to have a proportional relationship.

Answer:
less than
Step-by-step explanation:
Answer:
The set of natural numbers can be denoted as: {} (null set) because no natural number will satisfy the given equation.
Step-by-step explanation:
Given equation:
To find the set of natural numbers that satisfies the above equation.
Solution:
In order to find the set of solutions for the equation, we will solve it for 
We have:
Subtracting both sides by 8.
∴ 
Thus, we get only one solution for that satisfies the given equation but it is not a natural number. -3 is an integer.
Set of natural numbers {1,2,3,4,5,6........}
Thus, we can say the set of natural numbers that satisfies the equation is a null set {}.
Answer:
455 square kilometers
step-by-step explanation:
a = l • w
24 • 24
576
because there is a space where it isn’t shaded we have to find the area of that as well
11 • 11
121
now just subtract
576 - 121

Answer:
V = 0.52 cm³
Step-by-step explanation:
radius r = 0.5 cm
volume V = 0.523333333 cm³
surface area A = 3.14 cm²
circumference C = 3.14 cm
In Terms of Pi π
volume V = 0.166666667 π cm³
surface area A = 1 π cm2
circumference C = 1 π cm
Agenda: r = radius
V = volume
A = surface area
C = circumference
π = pi = 3.1415926535898
Formulas:
Sphere Formulas in terms of radius r:
Volume of a sphere:
V = (4/3)πr³
Circumference of a sphere:
C = 2πr
Surface area of a sphere:
A = 4πr²
