15 machines * 15 minutes = 500
75 machines * x = 6000
by dividing both equations we have
(75*x)/(15*15) = 6000/500
solving for x
x = 36
it would take 36 min
Answer:
96 square units
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.
My answer:
- The length of the large rectangle is: 5
- The width of the large rectangle is: 7
=> Area of the large rectangle = length × width = 7*5 = 35 square units
- The length of the middle rectangle is: 7
- The width of the middle rectangle is: 4
=> Area of the middle rectangle = length × width = 7*4 = 28 square units
- The length of the small rectangle is: 7
- The width of the small rectangle is: 3
=> Area of the small rectangle = length × width = 7*3 = 21 square units
Area of top and the bottom triangles =2*
Total surface area = 35 + 28 + 21 + 12 = 96 square units
Answer:
136.36 meters
Step-by-step explanation:
we know that
Chelsea sprinted 150 yards in 21.5 seconds
convert yards to meters
Remember that
One meter is approximately equal to 1.1 yards
So
Divide by 1.1
![150\ yd=150/1.1=139.36\ m](https://tex.z-dn.net/?f=150%5C%20yd%3D150%2F1.1%3D139.36%5C%20m)
therefore
Chelsea sprinted 136.36 meters in 21.5 seconds
Answer:
One of the most prevalent applications of exponential functions involves growth and decay models. Exponential growth and decay show up in a host of natural applications. From population growth and continuously compounded interest to radioactive decay and Newton’s law of cooling, exponential functions are ubiquitous in nature. In this section, we examine exponential growth and decay in the context of some of these applications.
Answer:
![a_n = 10-3(n - 1)](https://tex.z-dn.net/?f=a_n%20%3D%2010-3%28n%20-%201%29)
10 + 7 + 4 + 1 + -2 + -5
Step-by-step explanation:
Explicit Arithmetic Formula: ![a_n = a_1 + d(n-1)](https://tex.z-dn.net/?f=a_n%20%3D%20a_1%20%2B%20d%28n-1%29)
To find <em>d</em>, take the common difference between 2 numbers.
To find the other terms of the sequence, plug them into the explicit formula or subtract 3 from the given numbers.
