Raul calculated that he would spend $125 on school supplies this year. He actually spent $87.50 on school supplies. What is Raul

mylen [45]

C - 30%.

We know he spends less than he has expected, so we put it as a fraction calculate the percentage of the error.

So it would be:

87.5/ 125 = 0.7

And 1-0.7 = 0.3

When we move the chemical place two places to the left to make it a percentage, it will become 30%.

Sandra saves 14% of her salary for retirement. This year her salary was $2,000 more than in the previous year, and she saved $7,

Brums [2.3K]

Answer: Sandra's salary in the previous year was $48,000

Step-by-step explanation:

Hi, the expression given is missing the $2000 more that she earns this year.

0.14 (x +2000) =7000

Where:

<em>x is Sandra's salary in the previous year. </em>
<em>0.14 is the decimal form of 14% (14/100=0.14) </em>

Solving for x :

0.14(x) +0.14 (2000) =7000

0.14x +280 =7000

0.14 x = 7000-280

0.14x = 6720

x = 6720/0.14

x=48,000

Sandra's salary in the previous year was $48,000

Feel free to ask for more if needed or if you did not understand something.

Which equations represent the asymptotes of the hyperbola (x-1)^2/36-(y-2)^2/64=1 ?

allochka39001 [22]

Answer:

$4x+3y=10$ and $4x-3y=-2$

Step-by-step explanation:

The asymptote equation of a translate hyperbola with equation $\frac{(x-h)^2}{b^2}-\frac{(y-k)^2}{a^2}=1$ is $y=\pm\frac{b}{a}(x-h)+k$

The given hyperbola has equation: $\frac{(x-1)^2}{36}-\frac{(y-2)^2}{64}=1$

Or $\frac{(x-1)^2}{6^2}-\frac{(y-2)^2}{8^2}=1$

Comparing to $\frac{(x-h)^2}{a^2}-\frac{(y-k)^2}{b^2}=1$

We have a=6 and b=8, h=1 and k=2.

We substitute this values to get:

$y=\pm\frac{6}{8}(x-1)+2$

$y=\pm\frac{4}{3}(x-1)+2$

$3y=\pm4(x-1)+6$

We split the plus or minus sign to get:

$3y=4x-4+6$

$3y=4x+2$

$3y-4x=2$

Or

$3y=-4(x-1)+6$

$3y=-4x+4+6$

$3y+4x=10$
