The time required for a trip of a certain distance in a car varies indirectly as the rate the car travels. A trip took 18 hours traveling at 50 miles per hour. How long would this trip take if the car was traveling at 75 miles per hour?
Answers
Answer:
The answer is 12.
Step-by-step explanation:
If you multiply 18 by 50, you would get how long the trip is, which is 900 miles. Then, divide 900 by 75, you would then get the answer of 12. The trip would take 12 hours at 75 mph.

A parking garage charges $5 for the first hour, $10 for up to 2 hours, and $12 for the entire day. Let G be the dollar cost of parking for t hours
Answers
Answer:
Cost is G for t hours =[tex]\left \{ {5t for{t=0 <t<2} \atop 12 for{t >2}} \right.[/tex]
Step-by-step explanation:
According to question parking garage takes
5$ for 0 to 1hr
10$ for 0 to 2hr and
12$ for 0 to 24hr
Let t be the time for which car is parked in garage and the total cost is G then
G =[tex]\left \{ {5t for{t=0 <t<2} \atop 12 for{t >2}} \right.[/tex]
therefore cost is G =[tex]\left \{ {5t for{t=0 <t<2} \atop 12 for{t >2}} \right.[/tex]
The cost of parking a car for 5 hours is required.
Cost of 5 hours will be $25.
The cost of parking for each hour = $5
The cost of parking for entire day = $120
Let [tex]t[/tex] be the number of hours
[tex]G[/tex] be the total cost.
The function will be
[tex]G(t)=5t[/tex]
The cost at 5 hours will be
[tex]G(5)=5\times 5=25[/tex]
So, cost of 5 hours will be $25.

Tina has a pet sitting business. She charges a flat service fee of $30, plus $20 per day for each animal. If one of her customers spent less than $170 on one animal, which of the following inequalities could be used to solve for x, the number of days the customer paid for pet sitting?
A.
$20x < $170
B.
$20x + $30 < $170
C.
$20x < $200
D.
$20x - $30 < $200
Answers
Answer:
Option B: $20x + $30 < $170 is the correct answer.
Step-by-step explanation:
Given that:
Service fee of Tina's business = $30
Per day charges = $20
Number of days = x
Customer's budget = less than $170
According to given statement;
20x + 30 < 170
Hence,
Option B: $20x + $30 < $170 is the correct answer.

Find x so that x, X +2, X'+3 are the first three terms of a geometric sequence. Then find the 5" term of the
sequence.
Answers
Answer:
The fifth term is -1/4.
Step-by-step explanation:
We know that the first three terms of the geometric sequence is x, x + 2, and x + 3.
So, our first term is x.
Then our second term will be our first term multiplied by the common ratio r. So:
[tex]x+2=xr[/tex]
And our third term will be our first term multiplied by the common ratio r twice. Therefore:
[tex]x+3=xr^2[/tex]
Solve for x. From the second term, we can divide both sides by x:
[tex]\displaystyle r=\frac{x+2}{x}[/tex]
Substitute this into the third equation:
[tex]\displaystyle x+3=x\Big(\frac{x+2}{x}\Big)^2[/tex]
Square:
[tex]\displaystyle x+3 = x\Big( \frac{(x+2)^2}{x^2} \Big)[/tex]
Simplify:
[tex]\displaystyle x+3=\frac{(x+2)^2}{x}[/tex]
We can multiply both sides by x:
[tex]x(x+3)=(x+2)^2[/tex]
Expand:
[tex]x^2+3x=x^2+4x+4[/tex]
Isolate the x:
[tex]-x=4[/tex]
Hence, our first term is:
[tex]x=-4[/tex]
Then our common ratio r is:
[tex]\displaystyle r=\frac{(-4)+2}{-4}=\frac{-2}{-4}=\frac{1}{2}[/tex]
So, our first term is -4 and our common ratio is 1/2.
Then our sequence will be -4, -2, -1, -1/2, -1/4.
You can verify that the first three terms indeed follow the pattern of x, x + 2, and x + 3.
So, our fifth term is -1/4.

For fx), evaluate the following:
a. (0)
b. (6)
Answers
Answer:
a. f(0) = 4
b. f(6) = 8
Step-by-step explanation:
Let us solve the question
∵ f(x) = x + 4 if x < 5 ⇒ First part
→ That means if x less then 5 we will use this part of f(x)
∵ f(x) = 8 if 5 ≤ x < 7 ⇒ Second part
→ That means if x = 5 or greater than 5 and less than 7, we will use
this part of f(x)
∵ f(x) = 2x - 1 if 7 ≤ x ≤ 10 ⇒ Third part
→ That means if x equal 7 or greater than 7 and less than 10 or equal 10,
we will use this part of f(x)
a. The value of f(0)
∵ x = 0
∵ 0 < 5
→ That means we will use the first part of f(x)
∵ f(x) = x + 4
∴ f(0) = 0 + 4
∴ f(0) = 4
b. The value of f(6)
∵ x = 6
∵ 6 is between 5 and 7
→ That means we will use the second part of f(x)
∵ f(x) = 8
→ It means the value of f(x) is 8 for any values of x from 5 to less than 7
∴ f(6) = 8
