Ajay is researching how the population of his hometown has changed over time. Specifically, he learns his hometown had a populat

ion of 20{,}00020,00020, comma, 000 in 199019901990, and that the population has since increased by about 8\%8%8, percent every 333 years.
Ajay predicts that his town can only support a population of 50{,}00050,00050, comma, 000. Ajay is relieved to see that population has not exceeded 50{,}00050,00050, comma, 000 ttt years after 199019901990.

There were 8,651 deaths and 14,662 births reported in Hillsborough County in the year 2000. If there were 998,948 people living
alexdok [17]

Crude birth rate is all the time reported per 1000 living people.

To compute for this, the formula is number of births x 1000 divided by the estimated population at midyear. So plugging in the values given:

14,662 x 1000 divided by 994,948

= 14662000 / 994948

= 14.68 per 1000 living people.

Alex's friend Pablo comes up with an exact equation to find out how many bags he needs. Use his equation
Bezzdna [24]

Answer:

8.5 bags are needed.

Step-by-step explanation:

Given : Number of bags needed B=x(2x+7)+3(2x+7)+(x+4)

            (2x + 7) = 4

To Find :  how many bags he needs?

Solution :

(2x + 7) = 4

2x=-3

x=-\frac{3}{2}

Now we are given that Number of bags needed B=x(2x+7)+3(2x+7)+(x+4)

Substitute the value of x

B=(\frac{-3}{2})(2(\frac{-3}{2})+7)+3(2(\frac{-3}{2})+7)+((\frac{-3}{2})+4)

B=8.5

Hence 8.5 bags are needed.

A rectangular tank that is 5324 ft cubed with a square base and open top is to be constructed of sheet steel of a given thicknes
marishachu [46]

Answer:

Side of 22 and height of 11

Step-by-step explanation:

Let s be the side of the square base and h be the height of the tank. Since the tank volume is restricted to 5324 ft cubed we have the following equation:

V = s^2h = 5324

h = 5324 / s^2

As the thickness is already defined, we can minimize the weight by minimizing the surface area of the tank

Base area with open top s^2

Side area 4sh

Total surface area A = s^2 + 4sh

We can substitute h = 5324 / s^2

A = s^2 + 4s\frac{5324}{s^2}

A = s^2 + 21296/s

To find the minimum of this function, we can take the first derivative, and set it to 0

A' = 2s - 21296/s^2 = 0

2s = 21296/s^2

s^3 = 10648

s = \sqrt[3]{10648} = 22

h = 5324 / s^2 = 5324 / 22^2 = 11

Put these measurements in order from largest to smallest: 9000ml, 0.048 kl, 4.8L
Helen [10]

As the highest measurement unit given is KL, we will convert the other values to KL to arrange from largest to smallest or descending order.

Converting the given values we get:

9000 ml =  0.009 KL

4.8 L = 0.0048 KL

Third given is 0.048 KL

So, now arranging them from largest to smallest we get,

0.048 KL, 0.009 KL, 0.0048 KL

Hence the correct order is:

0.048 KL, 9000 ml, 4.8 L

Nicholas scoops a few gum balls into his bag when he weighs it he finds that he scooped 0.76 pounds how much will the gum balls
11111nata11111 [884]

Answer:

The cost of 0.76 pound gum ball is $2.6448

The cost of 1.5 pounds of sour patch kids is $5.985

Step-by-step explanation:

Consider the provided information.

Nicholas scoops a few gum balls into his bag when he weighs it he finds that he scooped 0.76 pounds. The cost of 1 pound of gum balls is $3.48

This can be written as:

1 pound gum ball= $3.48

Multiply both the sides by 0.76

1×0.76 pound gum ball= $3.48×0.76

0.76 pound gum ball= $2.6448

Hence, the cost of 0.76 pound gum ball is $2.6448

Nichols has decided to buy 1.5 pounds of sour patch kids and the cost of 1 pound of sour patch kids is $3.99

This can be written as:

1 pound sour patch kids = $3.99

Multiply both the sides by 1.5

1×1.5 pound sour patch kids = $3.99×1.5

1.5 pound sour patch kids = $5.985

Hence, the cost of 1.5 pounds of sour patch kids is $5.985
