Call the amount of chips ordered : x
-> The amount of hot dogs ordered : 4x
Since there are a total of 20 chips and hot dogs orders, x + 4x = 20 -> 5x = 20
-> x = 20/5 = 4
-> 4x = 4 x 4 = 16
So, there are 16 hot dogs and 4 chips ordered.
Answer:
16 hot dogs
4 chips
Step-by-step explanation:
Let h = number of hot dogs ordered
Let c = number of chips ordered
Given:
Total number of orders = 20Four times as many hot dogs as chips ordered⇒ h + c = 20
⇒ h = 4c
Substitute h = 4c into h + c = 20 and solve for c:
⇒ 4c + c = 20
⇒ 5c = 20
⇒ c = 4
Substitute found value for c into h = 4c and solve for h:
⇒ h = 4 × 4
⇒ h = 16
Therefore, 16 hot dogs and 4 chips were ordered.
Elena and her mom are on a road trip outside the United States. Elena sees this road sign (Maximum 80). Elena's mom is driving 75 miles per hour when she gets pulled over for speeding. The police officer explains that 8 kilometers is approximately 5 miles. If the speed limit is 80 kilometers per hour, and Elena's mom was driving 75 miles per hour, was she speeding? How many kilometers per hour was she OVER THE SPEED limit of 80kph?
Given :
Maximum speed limit, s = 80 km/hr
Elena's mom is driving at u = 75 mph.
The police officer explains that 8 kilometres is approximately 5 miles.
To Find :
Was she speeding and by how many km/hr.
Solution :
It is given that 8 km = 5 miles
So,
[tex]1\ miles=\dfrac{8}{5}\ km\\\\1\ miles = 1.6\ km[/tex]
Now, Speed of Elena's mom in km/hr is :
[tex]Speed =\dfrac{75\ miles\times\dfrac{1.6\ km}{1\ miles} }{1 \ hour}\\\\Speed = \dfrac{120\ km}{1 \ hour}\\\\Speed = 120\ km/hour[/tex]
Yes, she is over speeding and by ( 120 - 80 ) = 40 km/hr.
Hence, this is the required solution.
Elena's mom was driving at 120 km per hour, with which she was effectively speeding, exceeding the allowed speed by 40 km per hour.
To determine if Elena's mom was speeding and to determine how many kilometers per hour was she over the speed limit of 80kph the following calculation should be performed:
5 = 8 75 = X 75 x 8/5 = X 120 = X
Therefore, Elena's mom was driving at 120 km per hour, with which she was effectively speeding, exceeding the allowed speed by 40 km per hour.

A brand new smartphone costs $1200. It decreases in value by 13. 3% every year
after its purchase. Which function models the value of the phone x years after its
puchase?
A. F(x) = 1200(0. 867)^x
B. F(x) = 1200(1. 133)^x
C. F(x) = 1. 133(1200)^x
D. F(x) = 0. 867(1200)^x
The function of the brand new smartphone is an exponential function
The function that models the value of the phone x years after its puchase is f(x) = 1200(0.867)^x
How to model the function?The given parameters are:
Initial value (a) = $1200
Rate (r) = 13.3%
An exponential function that represents a decrement in value is illustrated using:
[tex]f(x) = a(1 - r)^x[/tex]
Substitute known values
[tex]f(x) = 1200(1 - 13.3\%)^x[/tex]
Evaluate the difference
[tex]f(x) = 1200(0.867)^x[/tex]
Hence, the function that models the value of the phone x years after its puchase is f(x) = 1200(0.867)^x
