Assume you have a balance of $1,900 on a credit card.
dimaraw [331]

principal=$1900

rate =13.6 %

simple interest= $35

Time=?

SIMPLE INTEREST ={PRINCIPAL×RATE×TIME}/{100}

$35= {$1900 ×13.6× TIME}{100} /

$35×100=25840× TIME

TIME=\bold\frac{ 3500}{25840}

TIME=700/5168

TIME={\tt{\green{\underline{\underline{\huge{0.1354489164}}}}}} years

You work for a company that produces custom picture frames. A new customer needs to frame a piece of rectangular artwork with di
miskamm [114]

Answer:

None of the choices are correct.

Step-by-step explanation:

Let x be the width of the frame,

The framed art cannot me more than 320 square inches

(11 + 2x) \times (15+2x) \leq 320

(165 +30x +22x +4x^2 ) \leq 320

4x^2+52x + 165 \leq 320

4x^2 +52x + 165-320 \leq 0

4x^2 +52x - 155\leq 0

By using the quadratic formula

x = \frac{-b\pm \sqrt{(b^2-4ac)}}{2a}

x = \frac{-52\pm \sqrt{(52^2-4(4)(-155))}}{2(4)}

x = \frac{-52\pm \sqrt{(2704+2480)}}{2(4)}

x = \frac{-52\pm \sqrt{(5184)}}{2(4)}

x = \frac{-52\pm 72}{2(4)}

x = \frac{20}{8}

x= \frac{5}{2}

x = 2.5

Frame must not be more than 2.5 inches wide.

Which table shows input and output values that represent a linear function?
shepuryov [24]

Answer:

Table A

Step-by-step explanation:

In order for it to be a linear relationship, the change in the x values and y values (f(x)) needs to be consistent.

In every table, the x values change the same, so we can focus on the y values.  

Notice in table A, the f(x) values go down consistently by 10 for every change in x.  

All of the other tables are not consistent.  

Therefore, table A is the only linear function.
