Juanita borrowed $600 to purchase a new computer. She was charged 7% interest for two years. She used the simple interest formula to find the interest.

I = 600(7)(2)

What error did Juanita make and how will her error affect the interest she calculates? Explain

Answers

Answer 1

Answer:

The correct formula should be I= 600(0.07)(2). Juanita made a very common error, she didn't put the percentage of interest in decimal form; or she didn't put the percent sign on it so we know to put it in decimal form. Her error will make a big difference; with using her calculations the answer would be $8,400. With the correct formula the answer is $84.

Hope this help! :)

Answer 2

Given :-

Juanita borrowed $600 .Rate of Interest = 7% .Time = 2yrs .

To find :-

Error made by her.

Answer :-

As we know that the formula for Simple interest is ,

SI = P*R*T / 100

Substitute ,

I $600* 7 * 2 / 100 I = $ 84 .

So here she did not write 7 % as 7/100 instead she wrote 7 .

: Santiago realizó los siguientes movimientos en su Cuenta bancaria: el lunes consignó $300.000, el martes retiró $120.000, el miércoles retiró $95.000 Y el jueves consignó $80.000. ¿Cómo se representan matemáticamente los movimientos bancarios de Santiago?

Answers

Answer:

Step-by-step explanation:

Los movimientos bancarios de Santiago se representan matemáticamente teniendo en cuenta que consignar es sumar y retirar el restar. Por lo tanto podes expresar los movimientos bancarios de la siguiente manera:

Lunes → + 300.000Martes → -120.000Miércoles → -95.000Jueves → +80.000

Al realizar la sumatoria se obtiene:

 +300.000 - 120.000 - 95.000 + 80.000 = + 165.000

En la semana Santiago obtiene en su cuenta bancaria $165.000

A point P os equi distant from R(-2,4) and S(6,-4) and its x co ordinate is twice its Y co ordinate find co ordinates of P

Answers

Answer: [tex]P(-4,-2)[/tex]

Step-by-step explanation: Distance between two points is calculated as

[tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]

Equidistant means the same distance, i.e., the distance between points P and R is equal to the distance between points P and S.

Suppose P's y-coordinate is a. If its x-coordinate is double, then

(x,y) = (2a,a)

Thus

[tex]\sqrt{(2a+2)^{2}+(a-4)^{2}} =\sqrt{(2a-6)^{2}+(a+4)^{2}}[/tex]

Solving

[tex]4a^{2}+8a+4+a^{2}-8a+16=4a^{2}-24a+36+a^{2}+8a+16[/tex]

[tex]5a^{2}+20=5a^{2}-16a+52[/tex]

[tex]-16a=32[/tex]

[tex]a=-2[/tex]

y-coordinate is [tex]-2[/tex], then x-ccordinate is

2a = 2(-2) = [tex]-4[/tex]

Coordinates of point P equidistant for R and S is [tex](-4,-2)[/tex].

What is the equation of the axis of symmetry of the parabola y=-2x^2+8x-7?
x=.....

Answers

Answer:

Equation of axis of symmetry is x = 2

Step-by-step explanation:

The equation of the parabola is given as;

y = -2x² + 8x - 7

The equation of the axis of symmetry is given by;

x = -b/2a

In the parabola equation given and using letters of quadratic equation, we can say that;

a = - 2

b = 8.

c = -7

Thus;

x = -b/2a = -8/(2 × - 2)

x = 8/4

x = 2

Equation of axis of symmetry is x = 2

Given the slope and one point on the line:
m = -2
(7,-3)
Write the linear equation in standard form:

Answers

Answer:

y= -2x + 11

Step-by-step explanation:

standard form for lines is y=mx+b

m is the slope and b is the y intercept

we already know that m is -2, so we just need to figure out the intercept.

the point given is (7,-3)

points are written as (x,y) so we can plug it into the equation with 7 for the x and -3 for y

-3 = -2 (7) + b

-3 = -14 + b

11 = b

so the equation is y=-2x+11

Given:

The number is [tex]-\dfrac{7}{5}[/tex].

To find:

The location of the given number of the number line.

Solution:

We have,

[tex]Number=-\dfrac{7}{5}[/tex]

It can be written as

[tex]Number=-\dfrac{5+2}{5}[/tex]

[tex]Number=-\dfrac{5}{5}-\dfrac{2}{5}[/tex]

[tex]Number=-1-\dfrac{2}{5}[/tex]

It means the number is less than -1 but more than -2. So, the number lies between -2 and -1.

The mixed fraction form of given number is

[tex]Number=-(1+\dfrac{2}{5})[/tex]

[tex]Number=-(1\dfrac{2}{5})[/tex]

[tex]Number=-1\dfrac{2}{5}[/tex]

Divide the number in 5 equal parts between two consecutive integers.

Now each unit represents [tex]\dfrac{1}{5}[/tex].

Since [tex]Number=-1-\dfrac{2}{5}[/tex], therefore, it is 2 units left from -1.

I won a sweepstakes and will receive money every week for 52 weeks. The first week, I will receive $500 and every week after that I will receive $50 more than I received the previous week. How much money will I receive over the course of the 52 Weeks?
25 Points.

Answers

Answer:

$3100

Step-by-step explanation:

You can determine this by multiplying 52 by 50, because you get 50 dollars for 52 weeks, then add 500 to it, because you get 500 dollars at first. 52 times 50 is equal to 2600, and 2600 + 500 is equal to 3100. You will receive $3100 over the course of 52 weeks.

How far is the star away from

its about 27k AU away

Answer:

6623 AU

Step-by-step explanation:

I assume the angle measure 0.000302 is in radians.

Draw a segment from the Sun to the Star.

Use the upper small triangle.

The angle at the Star measures 0.000151 radians.

The opposite leg measures 1 AU.

We need the hypotenuse which is the distance from the Star to Earth.

sin A = opp/hyp

sin 0.000151 rad = 1/x

x sin 0.000151 rad = 1

x = 1/(sin 0.000151 rad)

x = 6623
