The perimeter of a rectangular metal plate is 15 cm. Find the length of the rectangular plate (in decimals) whose width is 228 c

scoray [572]

The Solution.

Representing the problem in a diagram, we have

By formula,

$P=2(L+W)$

In this case,

$P=15\operatorname{cm},L=?,W=\frac{22}{8}cm$

Substituting these values in the formula above, we get

$15=2(L+\frac{22}{8})$

Clearing the bracket, we get

$15=2L+(2\times\frac{22}{8})$ $\begin{gathered} 15=2L+\frac{11}{2} \\ \\ 15=2L+5.5 \end{gathered}$ $\begin{gathered} 15-5.5=2L \\ 9.5=2L \end{gathered}$

Dividing both sides by 2, we get

$L=\frac{9.5}{2}=4.75\approx4.8\operatorname{cm}$

Therefore, the correct answer is option C.

topjm [15]

Answer:

x = $20/day, y = $0.35/mile

Step-by-step explanation:

x = $/day, y = $/mile

4x + 160y = 136

1x + 240y = 104

You can solve by elimination or substitution.

Jerry has a part-time job at a supermarket. The ordered pairs show the number of hours he worked for (input values) and the numb

Karo-lina-s [1.5K]

Answer:

Yes

Step-by-step explanation:

The ordered pairs are (6,72) (8,96) (5.5, 66) (9,108) (7,84).

The number of hours worked is $x$ and the money earned is $y$ .

Let us divide the values of $y$ by $x$

$\dfrac{72}{6}=12$

$\dfrac{96}{8}=12$

$\dfrac{66}{5.5}=12$

$\dfrac{108}{9}=12$

$\dfrac{84}{7}=12$

The fuction which defines the above ordered pairs is $y=12x$

It can be seen that the amount of money earned is 12 times the number of hours worked.

So, per hour Jerry earns 12 dollars.

Hence, the ordered pairs are relation.
