Answer:

The number of pounds of coffee in stock decreased by 9% each hour since the trend began.

There were 40 pounds of coffee in stock when the trend began.

Step-by-step explanation:

p(x)=0.4(.91)^x

      = a b^x

where a is the initial value and b = 1-rate of decrease

We know that the number of pounds of coffee will decrease as time goes on.

.4 is the initial value

It is in the hundreds of pound

.4 * 100 = 40 pounds

x is the number of hours

.91 = 1- rate of decrease

Subtract 1 from each side

.91-1 =-rate of decrease

-.09 = -rate of decrease

rate of decrease = .09

rate of decrease = 9 %

That means we keep 91 % of the coffee and sell 9% of the coffee


Lets check the statements:

There were 400 pounds of coffee in stock when the trend began.

False  there were 40 pounds when we started


The number of pounds of coffee in stock decreased by 9% each hour since the trend began.

True  see above calculations

False  see above calculations

Law of Sines

\frac{sin(A)}{a} =  \frac{sin(B)}{b}

\frac{sin(90)}{14.6} =  \frac{sin(45)}{x}

Cross multiply

x*sin(90) = 14.6sin(45)

x = 14.6sin(45)

What needs to be done to 21/10 to complete the problem? If you can, try to fix it yourself.<br><br>​
Olin [163]

Answer:

This is an improper fraction so we need to make it a mix fraction.

Step-by-step explanation:

21/10 = 10/10+10/10+1/10

10/10=1

So your final answer will be 2\frac{1}{10}

the perimeter of a square is 20 ft if you increase the length of the square by 2 feet and decrease the width by 1ft what is the
IrinaVladis [17]

Answer:

28 ft squared

Step-by-step explanation:

The 4 sides of a square are equal in length, so if the perimeter is 20ft that means each side would have to be 5ft, (20/4 = 5). If you increase the length by 2ft, one of the sides would now become 7ft (5+2 = 7). If you decrease the length of the other side by 1ft, the length would now be 4ft (5-1=4). Now to find the area, all you have to do is length * width. So you would do 7ft*4ft which is 28ft squared.
