Answer:

105.12 feets

Step-by-step explanation:

From the figure x we can identify a rectangle and a semicircle :

Area of rectangle = Length * width

Area = 8 * 10 = 80 feet²

The Area of a semicircle = 1/2πr²

Radius, r = 8 /2 = 4 feets

A = 1/2 * 3.14 * 4²

A = 3.14 * 8

A = 25.12 feet²

Area of figure = 80 + 25.12 = 105.12 feets

This is an exponential equation that can be represented by the following:

f(x) = a(b)^x

In this case...

25143 = a(0.66)^3

25143 is the population after 3 hours.

3 is the amount of time in hours.

0.66 represents the percent of the population remaining after each hour (66% as there is a 34% decline each hour).

We must solve for a, which is the initial population.

First, simplify (0.66)^3 to 0.2874.

25143 = 0.2874a

Now divide both sides by 0.2874 to isolate a.

a = 87455

There were initially 87,455 people within the city. I wouldn't want to be in that place!

A store manager predicts that 150 blankets will be sold if each blanket
Sever21 [200]

Answer:

$47

Step-by-step explanation:

Given: Store manager have predicted that 150 blanket can be sold at $32 each.

Also he has predicted sales of 2 blanket will decrease with $1 increase in price.

Now, finding price at which 120 blanket can be sold.

As we know cost of 150 blanket is $32 and we are finding for 120 blanket, which mean we have to increase price to decrease sales.

∴ 150-120 = 30\ blankets

Using unitary method to find correct price.

For 2 decrease in sales = $1 increase in price                

∴ 30 decrease in sales of blanket = $15 increase in price

Next, price of 120 blanket = Price of 150\ blanket + increase\ in\ price

Price\ of\ 120\ blanket = 32+15 = \$ 47

∴ $47 should be the price for at least 120 blanket to be sold.

How many solutions does y=2x+2,4x-2y=4 have?
Leni [432]
Write as a system y= 2 x + 2.4x - 2y = 4

{y = 4
{2x + 2.4x - 2y = 4

Substitute the value of y into the equation

2x + 2.4x - 2 x 4 = 4

Solve the equation

x= 30/ 11

A possible solution is

(x, y) = (30/11, 4)

Check the solution

4 = 2 x 30/11+ 2.4 x 30/11 - 2 x 4 = 4

Simplify the expression

4 = 4 = 4

The ordered pair is a solution

(x, y) = ( 30/11, 4)
