Pauline invested $10,000 at two different
rates, 4% and 6%. If her total interest income
was $470, how much did she invest at each
rate?

Answers

Answer 1

Answer:

So for this, I will be doing a system of equations. Let x = money invested at 4% and y = money invested at 6%. We know that x and y will total up to 10k since that's how much he initially invested, so that'll be one of our equations.

Our other equation will represent the total balance he has after investing. We know that x's interest is 4% (since the money is increasing, this would translate to 1.04 in decimal form) and y's interest is 6% (aka 1.06 in decimal form since its increasing) and that the total balance is 10470 (initial balance + interest income).

Step-by-step explanation:

Using all this info, these are our two equations:

X+Y=10000

1.04x+1.06=10470

Next, substitute x in the second equation for (10000 - y) and solve for y as such:

1.04(10000-y) +1.06y =10470

10400 - 1.04y + 1.60y = 10470

10400 + 0.02y = 10470

0.02y =70

y = 3500

Now that we have the value of y, substitute it into either equation to solve for x:

x + 3500 = 10000

x= 6500

1.04x + 1.06(3500)= 10470

1.04x = 6500

Answer

In short:

$6,500 was invested in the 4% rate

$3,500 was invested in the 6% rate

Find the slope of the line. 2x - 4y = 18

Answers

solve for y.
2x - 4y = 18
-4y = -2x + 18
y = 1/2x - 9/2
the slope is 1/2

Answer:

The slope would be 1/2.

Step-by-step explanation:

Step one: Subtract 2x from both sides to get, -4y=-2x+18

Step two: Divide -4 from all sides

The length is 20 m, the width is 10 m, and the area is 200 m.

Step-by-step explanation:

Here is why, since the length is 16 cm we first divide by 4 then multiply by 5. When we divide by 4 we get 4 and when we multiply by 5 to get 20. Then, we do the same for the width to get 10. Lastly, we just multiply both together.

A machine that fills bottles on an assembly line does so according to a normal distribution, where the mean amount of liquid poured into each bottle is 11.95 ounces with a standard deviation of 0.045 ounces. If more than 12.10 ounces is poured into a bottle, it will overflow and waste the liquid.

Required:
What is the probability that a bottle has more than 12.10 ounces poured into it, causing it to overflow?

Answers

Answer:

The probability is [tex]P( X > 12.10 ) =0.0004[/tex]

Step-by-step explanation:

From the question we are told that  

    The mean is  [tex]\mu = 11.95 \ ounce[/tex]

     The  standard deviation is  [tex]\sigma = 0.045 \ ounce[/tex]

 Generally the  probability that a bottle has more than 12.10 ounces poured into it, causing it to overflow is mathematically represented as

      [tex]P( X > 12.10 ) = P( \frac{X - \mu }{\sigma } > \frac{ 12.10 - 11.95}{0.045} )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

     [tex]P( X > 12.10 ) = P( Z > 3.33 )[/tex]

From the z table  the area under the normal curve to the right corresponding to  3.33   is

     [tex]P( Z > 3.33 ) = 0.0004[/tex]

=>  [tex]P( X > 12.10 ) =0.0004[/tex]

log ([tex]\frac{x^{3} x y^{6} }{z^{2} }[/tex])

Step-by-step explanation:

Given expression:

    3log x + 6log y - 2log z

We are to express the given log as single expression;

To solve this problem, we must apply some simple logarithmic rules.

      3log x + 6log y - 2log z;

First, re-write to give;

              x log y  = log yˣ

          3log x + 6log y - 2log z = log x³ + log y⁶ - log z²

   

Then,

            log t + log k - log y = log ([tex]\frac{t x k}{y}[/tex])

 log x³ + log y⁶ - log z² = log ([tex]\frac{x^{3} x y^{6} }{z^{2} }[/tex])

Also, when we make a quadratic curve around these data points we see that all of the data points will be closely related to the curve.

Hence, there is a strong association between the data points.

In the figure below, angle y and angle x form vertical angles. Angle x forms a straight line with the 50° angle and the 40° angle.


Write and solve an equation to determine the measure of angle y.

Answers

Answer:

The answer is "[tex]\angle y = 90^{\circ}[/tex]"

Step-by-step explanation:

Please find the image file of the angle in the attachment.

Each line is 180° straight because the [tex]\angle x[/tex]-axis of the 40° and 50° angles is a straight line:  

[tex]= \angle x + 40^{\circ} + 50^{\circ} = 180^{\circ}[/tex]

Use this formula and isolate x.

[tex]\angle x + 40^{\circ} + 50^{\circ} = 180^{\circ}\\\\ \angle x + 90^{\circ} = 180^{\circ} \\\\ \angle x = 180^{\circ} - 90^{\circ} \\\\ \angle x = 90^{\circ}\\\\[/tex]

Since the two are vertical angles, they have the same measurement. These have the same measurement.  If [tex]\angle x = 90^{\circ}[/tex] and [tex]m \angle x = m \angle y[/tex], then  [tex]\angle y = 90^{\circ}[/tex]

The local bowling alley charges $8 for 2 games of bowling and $3 for each additional game. You have a $20 bill. Let `x\ `stand for the total number of games you can bowl. Write an inequality to represent the total number of games you can bowl. Write the ORIGINAL inequality. Do NOT simplify.

Answers

Answer:

8 + 3x ≤ 20

Step-by-step explanation:

Given

2 Games = $8

Additional Game = $3

Amount = $20

Required

Determine the inequality that represents the number of games

From the question, we understand that the minimum number of games that can be played is 2.

So, the expression can be:

Cost of 2 games + Cost of additional games ≤ Amount

This gives:

8 + 3 * x ≤ 20

Where x represents the additional number of games

By simplifying the expression, we have:

8 + 3x ≤ 20
