Answer:
$132
Step-by-step explanation:
First we need to find the total number of woods required. This would be total area of fence divided by area of each wood. Remember to convert inch into feet.
Now we know the total number of planks, we need to find what is the cost of each plank. We know that one wood plank area is 2 sq. ft ( 6*0.33333). Therefore, the cost of each plank is = cost per area(sq.ft) multiply by total area (sq. ft).
cost per plank = 2 * $1.10 =$2.20.
We have total planks = 60 units and we have cost per plank = $2.20.
So, we can find total cost as 60*2.20= $132
Answer: The function that models the distance they drive is
f(x) = 50x + 20 where x is the time in hours
reasonable domain: 0 ≤ x ≤ 3
Step-by-step explanation:
examples:
95 = 50(1.5) + 20 After driving another hour and a half, they will have driven a total of 95 miles.
120 = 50(2) + 20 This means that after 2 more hours they will reach their destination.
There is a little ambiguity in the question. The function could be written as if they are starting out. f(x) = 50t
20 = 50(.4) At 50 mph it took .4 hours to go 20 miles.
120 = 5(2.4) The whole trip took 2.4 hours.
Answer:
-7 = -3x + b
Step-by-step explanation:
i'm guessing because you have not provided a visual so i can not determine the B.
Answer:
B. This relationship represents a function because no length of ribbon has more than one price.
Step-by-step explanation:
A relation is considered as a function when there is exactly just one possible range value that any of the domain value can give. In order words, each domain value of a function cannot have more than one range value.
In the given table of values representing the length and price of ribbon, the domain includes all the set of lengths of the ribbon while the range is the set of the corresponding prices the lengths can cost.
Thus, each length given has exactly just one price. No particular length has more than one price. Therefore, we can consider this as a function.
Answer:
The time taken by Macro to cover 200 m at the speed of 45 meter per minute is 4.44 minutes
Step-by-step explanation:
Given as :
The speed at which Macro swim = s = 45 meter per minute
The total distance cover by Macro = d = 200 meter
Let The time taken by Macro to cover 200 m = t minutes
<u>Now, From formula </u>
Distance = Speed × time
Or, d = s × t
Or, t = 
Or, t = 
Or, t = 4.44 minutes
So, The time taken by Macro to cover 200 m = t = 4.44 minutes
Hence The time taken by Macro to cover 200 m at the speed of 45 meter per minute is 4.44 minutes . Answer
