Roberta has $10,540 to invest. She plans to invest her money in certificates of deposit (CDs) that have 2.1% interest, a stock p

ira [324]

Answer:

The amount invested in CDs is $1,340

The amount invested in the stock portafolio is $6,900

The amount invested in the saving accounts is $2,300

Step-by-step explanation:

Let

x ---->the amount invested in CDs at 2.1%

y ---> the amount invested in the stock portfolio at 2.5%

z ---> the amount invested in the savings account at 1.5%

$x+y+z=10,540$ ----> equation A

$z=\frac{1}{3}y$ ----> equation B

substitute equation B in equation A

$x+y+\frac{1}{3}y=10,540$

$x+\frac{4}{3}y=10,540$

$x=10,540-\frac{4}{3}y$ ----> equation C

we know that

The total interest earned by the three amount must be equal to $231.69

$0.021x+0.025y+0.015z=231.69$ ----> equation D

substitute equation B and equation C in equation D

$0.021(10,540-\frac{4}{3}y)+0.025y+0.015(\frac{1}{3}y)=231.69$

solve for y

$221.34-0.0315y+0.025y+0.005y=231.69$

$0.0015y=231.69-221.34$

$0.0015y=10.35$

$y=\$6,900$

<em>Find the value of x</em>

$x=10,540-\frac{4}{3}(6,900)$

$x=\$1,340$

<em>Find the value of z</em>

$z=\frac{1}{3}(6,900)$

$z=\$2,300$

Kyle has a notebook for each of his 5 classes. he puts 6 stickers on each notebook. there are 10 stickers on each street. how ma

larisa86 [58]

Well if he puts 6 on each of the 5 notebooks, you'd do 5*6 and get 30. If 10 are on each sheet you'd do 30/10 & end up with 3 sheets of stickers :)

Choose the correct conic section to fit the equation.

erik [133]

Answer:

Circle

Step-by-step explanation:

The given equation is $x^2+y^2=16$

We know the standard equation of a circle is given by

$(x-h)^2+(y-k)^2=r^2$

Where, (h,k) is the center of the circle and r is the radius.

We can rewrite the given equation in this form

$(x-0)^2+(y-0)^2=4^2$

Hence, the center of the circle is (0,0) and radius is 4.

Thus, the given equation represents a circle.
