So, for the second problem, they've reversed the situation: Now we have the temperature, and we have to think backwards to figure out the number of cricket chirps (in five minutes)!
We ended up with 60 degrees (somehow). Well, let's subtract 37. That gives us 23. What does this number mean? It is the number of times the cricket chirps in 15 seconds. But we want five minutes... I bet you can take it from here... :)
Answer:
I would rather receive 763,210.
Step-by-step explanation:
I would receive 763,210 because it is more money than 763,201. It is 9 dollars more.
Answer:
Width=20 feet
Since Length=Width=20 feet, the rectangle is a Square.
Step-by-step explanation:
Area, ![A=40w - w^2](https://tex.z-dn.net/?f=A%3D40w%20-%20w%5E2)
To determine the width of the rectangle that gives the maximum area, we take the derivative of A and solve for its critical point.
![A'=40 - 2w\\$When A'=0\\40-2w=0\\40=2w\\w=20 feet](https://tex.z-dn.net/?f=A%27%3D40%20-%202w%5C%5C%24When%20A%27%3D0%5C%5C40-2w%3D0%5C%5C40%3D2w%5C%5Cw%3D20%20feet)
The width of the rectangle that gives the maximum area =20 feet.
Perimeter of a rectangle=2(l+w)
Perimeter of the rectangle=80 feet
2(l+w)=80
2l+2(20)=80
2l=80-40
2l=40
l=20 feet
Since the length and width are equal, the special type of rectangle that produces this maximum area is a Square.
92+65=157
157-14=143
Answer is 143
hope this helps:)
Hello!
Here are the steps to your problem:
3x + 5 = x - 3
3x -x = -3 -5
2x = -8
x = -4
I hope this helps you! Have a lovely day!
