Answer:

k= 0.8936

P = 53198890

Step-by-step explanation:

In 2008

t = 8
P= 7000

As per equation, P = 5.5e^kt

7000 = 5.5e^(8k)
e^(8k) = 7000/5.5
e^(8k) = 1272.7272
ln e^8k = ln 1272.7272
8k = 7.14891
k= 7.14891/8
k= 0.8936

In 2018, t= 18, k= 0.8936

P = 5.5e^(18*0.8936)
P = 53198890

Step-by-step explanation:

You subtract 13,270 by 6,570 and you get 6,700 pieces of blue paper. Then, you subtract 6,700 by 2,600 and you get 4,100 pieces of yellow paper. Finally, you add the total of pieces of white, blue, and yellow paper and you get 24,070 for the total.

An elevator can hold a maximum of 1500 pounds. An average child weighs 75 pounds and the average adult weighs 150 pounds. The el

CaHeK987 [17]

Let's take this problem step-by-step:

Let's first set up some variables:

c: # of children
a: # of adults

Let's examine the information given:

Elevator can hold a maximum of 1500 pounds

⇒ average child is 75 pounds

⇒ average adult is 150 pounds

⇒ therefore: $75c + 150a\leq 1500$

Elevator can fit no more than 14 people

⇒ therefore: $c + a \leq 14$

Let's graph the equations:

$75c+150a\leq 1500\\c+a\leq 14$

⇒ look at the image attached

The point at which the two graphs intersect:

⇒ is the solution that represents the amount of children and adults and

their combine weight

With the horizontal axis being the # of children and vertical axis being the # of adults:

⇒ the solution is 8 children and 6 adults

Answer: 8 children and 6 adults
