You are an urban planner assessing the growth of a city. Ten years ago, the city's population was 249,583. Its current population is 318,270. By about what percentage has the city grown over the past ten years? Can anyone explain this one?

Answers

Answer:

27.52%

Step-by-step explanation:

Given that an urban planner wants to assess the growth of a city

Population of the city before 10 years = 249583

Current population = 318270

Population grown =318270-249583 = 68687

Relative growth = growth/original population

Relative growth = $(68687)/(249583)\n=0.2752$

Percent growth = relative growth x100

Hence percent growth = 0.2752x100

27.52%

$318,270-249,583=68,687\n\n\begin{array}{ccc}249,583&-&100\%\n68,687&-&p\%\end{array}\n\ncross\ multiply\n\n249,583p=68,687\cdot100\ \ \ \ /:249,583\n\np\approx27.52\n\nAnswer:\nThe\ city\ grown\ over\ the\ past\ ten\ years\ at\ 27.52\%.$

The US exports 200 billion pounds of coal. How many tons does the US export?

Answers

200 billion is 200,000,000,000 lbs
1 ton is 2,000 lbs.
So 200,000,000,000/2,000 = 100,000,000 tons or 100 million tons.

2,000 = 1 ton . 2,000,000,000/2,000 = 1,000,000,000 or 100 million tons

• Buyers are charged a shipping fee of $4.75 for each scarf order.Which expression can you use to find the total price of a scarf order?
48s - 4.75
4.758 - 48
48s + 4.75
4.75s + 48
HELP NOW PLSSS I BEG YOU

Answers

Answer: 48s + 4.75

Step-by-step explanation:

Each scarf is sold for $48 which is why the total price of buying s scarves is 48s or 48*s.

Assuming a single order of scarves can contain more than one scarf then that means that for s scarves, the shipping fee will remain the same at $4.75.

Should this be the case then the expression for an order of scarves will be;

= 48s + 4.75

This shows the price of ordering s number of scarves plus the shipping cost of $4.75 for the order comprising s number of scarves.

Answer:

48s + 4.75

Answer:

$tan(\theta) = (3)/(4)$

Step-by-step explanation:

Remember the trigonometric ratios, keep in mind that the way the side is referred to is based on its position relative to the angle getting referenced. The side next to the referenced angle ( $\theta$ ) is called the adjacent side, the one opposite the angle is called the opposite side, and the side opposite the right angle of the triangle is called the hypotenuse.

$sin (sine) = (opposite)/(hypotenuse)\n\ncos (cosine) = (adjacent)/(hypotenuse)\n\ntan(tangent) = (opposite)/(adjacent)$

In this problem, one is asked to find the value of ( $\theta$ ) with regards to a trigonometric function. One is given the opposite and adjacent sides, it would make the most sense to use the trigonometric function (tangent). Substitute the sides into their respective place, and simplify to find the value of the trigonometric function.

$tan(\theta) =(15)/(20)\n\n\ntan(\theta)=(3)/(4)$

There is a discrete relationship between the number of workers and the number of bricks layed on a wall. Use this information to answer problems 9-11. What is the domain for the function that models the relationship between workers and bricks laid on the wall?

Answers

Answer: The domain of a function represents all the possible input values or independent variables that can be used in the function. In this case, the function models the relationship between the number of workers and the number of bricks laid on the wall.

To determine the domain, we need to consider what values the number of workers can take on in this relationship. Since the number of workers is discrete, it means that only whole numbers can be used to represent the number of workers. For example, you cannot have 2.5 workers.

Therefore, the domain of the function would be a set of whole numbers. We can represent this using interval notation as {0, 1, 2, 3, ...}, where the ellipsis (...) indicates that the pattern continues indefinitely.
