Answer:

2/5

Step-by-step explanation:

in 4/10, both the numerator (4) and denominator (5) are multiples of 2, as 4 = 2 * 2 and 10 = 2 * 5. thus, we can divide both the numerator and denominator by 2 to get

(4/2) / (10/2) = 2/5 as our answer.

Answer: y=2.5x-8, the two points necessary to graph would be (2,-3) and (0,-8)

Step-by-step explanation: If the line passes thru (2,-3), let us plug in and find c. -3-2.5(2)=c

-3-5=c

c=-8 so y=2.5x-8

The line will represent the graph of the equation y=2.5x-8.

The two points necessary to graph would be (2,-3) and (0,-8).

The slope-intercept form is y=mx+c

If the line passes through (2,-3),

let us plugin and find c.

So we get,

[tex]-3-2.5(2)=c[/tex]

[tex]-3-5=c[/tex]

[tex]c=-8[/tex]

So, The equation of the line is y=2.5x-8.

Answer:

2311.68 dollars

Step-by-step explanation:

12 900  *  7  * .0256 =

London paid interest of $2311.68 at the end of the loan.

Simple interest is interest that is only calculated on the initial sum (the "principal") borrowed or deposited.

The basic simple interest formula looks like this:

Simple Interest = Principal Amount × Interest Rate × Time

Given,

Principal amount = $12900

Rate of interest = 2.56%

Time = 7 years

Simple interest = Principal amount × Rate of interest × Time

                         = ($12900 × 2.56 × 7)/100

                         = ($33024 × 7)/100

                         = $231168/100

Simple interest = $2311.68

Hence, $2311.68 is amount of interest London paid at the end of the loan.

76 chess sets

Step-by-step explanation:
Since they bought 16 cases and each contains 18 sets, let's multiply them

16 x 18 = 288
There were already 16 sets before that so lets add those as well

288 + 16 = 304
Now since there are 4 teachers we divide this among them

304/4 = 76

76 is the answer.

Answer:

Part 1) 150

Part 2) 6

Step-by-step explanation:

Part 1) All you have to do is multiply 30 by 5, since 30 is only 20% of the number and you have to get to 100%

30×5 = 150

Part 2) There are multiple ways of doing this, but the way I did it is 30 divided by 100 so you have the number of each percentage. Then you multiply that number by 20 since you are trying to get 20%

30÷100 = 0.3

0.3×20 = 6

Answer:

The employers pay their employees based on hourly rates, commission and salary.

Step-by-step explanation:

The employees get their pay based on hourly rates that can range from a minimum hourly rate of say $12 per hour to any maximum figure like $40 per hour.

The final salary is based on the numbers of hours worked multiplied by the hourly rate.

Secondly, the pays are also commission based. That is your base salary plus the commission.

The salary is typical in management positions. These are not hourly based but a lump sum pay.

So, the correct answers are : commission, hourly pay and salary.
