The following table shows the cost for a person to go to the 4 - H Fair to go on a certain number of rides: Develop an equation

PtichkaEL [24]

In order to develop an equation, let's use the slope-intercept form of the linear equation:

$y=mx+b_{}$

Using the points (3, 13.5) and (5, 18.5) from the table, we have:

$\begin{gathered} (3,13.5)\colon \\ 13.5=3m+b \\ (5,18.5)\colon \\ 18.5=5m+b \end{gathered}$

Subtracting the second and the first equation:

$\begin{gathered} 5m+b-(3m+b)=18.5-13.5 \\ 2m=5 \\ m=2.5 \end{gathered}$

Now, finding the value of b:

$\begin{gathered} 13.5=3m+b \\ 13.5=7.5+b \\ b=13.5-7.5 \\ b=6 \end{gathered}$

So the equation that represents this table is y = 2.5x + 6

Looking at the options, the correct one is E (none of the above).

Find two different values that complete each expression so that the trinomial can be factored into the product of two binomials.

zalisa [80]

4s² + <u>14</u>s + 10
4s² + 4s + 10s + 10
2s(2s) + 2s(2) + 5(2s) + 5(2)
2s(2s + 2) + 5(2s + 2)
(2s + 5)(2s + 2)

4s² + <u>22</u>s + 10
4s² + 20s + 2s + 10
2s(2s) + 2s(10) + 1(2s) + 1(10)
2s(2s + 10) + 1(2s + 10)
(2s + 1)(2s + 10)

It could be equal to 14 or 22.

A production system has a total daily output of 400 units and a total labor of 350 hours, what kind of productivity measure can

fomenos

Answer:

1.14 products per hour of labor

Step-by-step explanation:

To calculate the daily productivity would be the amount of products per hour of labor.

That is: 400 products / 350 hours of labor, and that is approximately 1.14 products per hour of labor.

Which means that for every hour of labor, 1.14 products are produced in one day, which would be a factor of productivity.

(a) A photography student borrows RM2 500 to buy a camera. The bank loans this money at a rate of 9 % capitalized monthly. What

Monica [59]

Answer:

The student will have to reimburse 2,991.03 two years later.

Step-by-step explanation:

This is a compound interest problem:

The compound interest formula is given by:

$A = P(1 + \frac{r}{n})^{nt}$

In which A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the time the money is invested or borrowed for.

In this problem, we have that:

A is the amount the student will have to reimburse two years later.

P is his loan. so $P = 2,500$

The bank loans this money at a rate of 9 % capitalized monthly. This means that $r = 0.09$ and $n = 12$ , since the money is compounded monthly, this means, 12 times in a year.

He will have to reimburse two years later, so $t = 2$

$A = P(1 + \frac{r}{n})^{nt}$

$A = 2,500(1 + \frac{0.09}{12})^{24}$

$A = 2,991.03$

The student will have to reimburse 2,991.03 two years later.
