Answer:

160/3 = 53 1/3

Step-by-step explanation:

When you divide fractions, you change the sign to multiplication and multiply by the reciprocal so in this case it would be

40/1 x 4/3 = 160/3

The figure shows a square, a regular pentagon and a regular hexagon put together. What is the measure of ∠BAC

Elan Coil [88]

Answer:

Step-by-step explanation:

One angle of a regular pentagon = 108°

One angle of a regular hexagon = 120°.

One angle of a square = 90°

∴ ∠BAC = 360 – (108 + 20 + 90) 360 – 318 = 42°

Write the linear system:

notsponge [240]

Answer:

(See explanation for further details).

Step-by-step explanation:

C) The linear system is:

$(-1)^{2} \cdot a + (-1)\cdot b + c = 5$

$c = - 4$

$(4)^{2}\cdot a + (4)\cdot b + c = 0$

After some algebraic handling:

$a - b + c = 5$

$c = -4$

$16\cdot a + 4\cdot b + c = 0$

By direct substitution:

$a - b - 4 = 5$

$16\cdot a + 4\cdot b - 4 = 0$

$a - b = 9$

$4\cdot a + b = 1$

$a = 9 + b$

$4\cdot (9+b)+b = 1$

$36 + 5\cdot b = 1$

$5\cdot b = -35$

$b = -7$

$a = 2$

D) The parameter values are: $a = 2$ , $b = -7$ , $c = -4$

E) The quadratic equation is $y = 2\cdot x^{2} - 7\cdot x -4$

To borrow money, you pawn your guitar. Based on the value of the guitar, the pawnbroker loans you $

Nonamiya [84]

$\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\to &\$1472\\
P=\textit{original amount}\to& \$1080\\
r=rate\\
t=years\to &\frac{1}{12}
\end{cases}
\\\\\\
1472=1080\left(1+r\cdot \frac{1}{12}\right)$

notice, it was pawned for only 1 month, so the "yearly" rate is for 1 month, which is 1/12 of the year, since a year has 12 moths

you'll get a rate in decimal terms, to get the % amount, just multiply it times 100
