Answer:
4n and 5p
Step-by-step explanation:
Because if it the cost of each your mulitplying and because you wanting to just define the variable p for pen and n for notebook all a variable is a letter than let you know what something is for using in math later
For this case, the first thing we should use is the following equation:
c (w) = 0.013w ^ 2-w-7
We note that w = 20 belongs to the interval [5, 30]. Therefore, we can use the equation.
Substituting w = 20 we have:
c (20) = 0.013 * (20) ^ 2- (20) -7
c (20) = - 21.8
Answer:
the wind chill temperature at 0f if the wind speed is 20 miles per hour is:
c (20) = - 21.8
Answer:
6.09+3.84=9.93 is the desired answer
Step-by-step explanation:
Cashews total cost step by step
1.74×3.5
Multiply 1.74 and 3.5 to get 6.09.
6.09
Peanuts total cost step by step
1.92×2
Multiply 1.92 and 2 to get 3.84.
3.84
Aloha!
1 centimeter= 40 kilometers
The distance between the cities in centimeters is 21.7
To get the answer into kilometers, you multiply.
So, 21.7 times 40 which is 868 kilometers.
To answer your question, the distance between Fort Worth and El Paso is 868 kilometers.
I hope this helps!
Adios!:)
Ok, lets visualize this scenario. We have a tank that is holding10450 ml of water. Then it tells use it is leaking at a rate of 270 ml per minute. Well, leaking would suggest something is being subtracted. Also, per minute means it is being subtracted each minutes so we use an x to represent the minutes. Ok, lets build the model
10450 - 270x = 0
The model above will tell us how many minutes it will take for the tank to be empty.
If we insert a number for x, the model below will tell us how many ml has leaked for the number of minutes we inserted into x.
10450 - 270x
