The total assets of Casper Inc 1.5 million is higher than SL $50,000 thus option (C) is correct,

The number system is a way to represent or express numbers.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.

As per the given,

Casper shows goodwill worth $1.5 million and JSL Inc.'s

goodwill is worth $50,000.

Since, $1 million = $1000000

Thus, $1.5 million = $1500000

Therefore,  $1500000 > $50,000

Hence "The total assets of Casper Inc 1.5 million is higher than SL $50,000".

Answer:

13*3+13=52

Step-by-step explanation:

13*3=39

39+13=52

The unknown number will be equal to 13.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that one number is three times another number and their sum is 52. The number will be calculated as,

3n + n = 52

4n = 52

n = 52 / 4

n = 13

Hence, the unknown number is 13.

Answer:

A) doubling time growth model

Step-by-step explanation:

Doubling time growth model can be defined as the total or overall number of time it takes for a specific quantity to increase by doubling in value or size at a constant growth rate.

Mathematically, the doubling time growth model is given by the rule of 70;

[tex]dt = \frac{70}{r}[/tex]

Where,

dt represents the doubling time.

r is the growth rate.

Hence, a doubling time growth model would best describe the population of a city if it increases in size by a factor of two every 29 years. The doubling time growth model is typically used to study or model the human population growth.

Answer:

64.8% of elephants were killed for ivory

Step-by-step explanation:

divide the number of elephants killed for ivory by the total number of elephants killed: 186÷287= 0.6780

multiply your answer by 100 to get a percentage: 0.6780 x 100= 67.8%

67.80% percent of the total elephants killed does this number represent.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is primarily used to compare and determine ratios and is represented by the symbol %.

Given:

Total elephants killed for ivory= 186

Total elephants killed = 287.

So, the  percent of the total elephants killed does this number represent

= 186 / 287 x 100

= 0.6780 x 100

=67.80%

Hence, the 67.80% percent of the total elephants killed does this number represent.

================================================================

Explanation:

S = number of tons of sugar

150S = cost of transporting all S tons of sugar

150S+4500 = total cost since we add on the $4500 fixed cost

C = 150S+4500 is the cost equation

--------------------------

If we replace C and S with y and x (in that order), then the equation turns into y = 1500x+4500

To graph this, you only need two points since this is a linear equation in the form y = mx+b. We have m = 1500 as the slope and b = 4500 as the y intercept.

To find a point, you plug in some number for x to get a corresponding y value. For instance, if x = 0

y = 1500x+4500

y = 1500(0)+4500

y = 4500

Showing (0,4500) is the y intercept and one point on the line

Now plug in x = 1

y = 1500x+4500

y = 1500(1)+4500

y = 6000

Showing (1,6000) is another point on the line

You can keep going to generate more points, but two is enough.

The graph will be a straight line through (0,4500) and (1,6000)

Answer:

Interest earned after 12 years is $48,000.

Step-by-step explanation:

The first step is to find 4% of 10,000

10,000 times .4 equals to 4,000

4% of 10,000 is 4,000

So each year, $4,000 is added

Times $4,000 by 12 years and you will have the total interest earned.

In case you need to know, the total amount of the bank account should be $58,000.
