Triangle CDE is an isosceles triangle with angle d congruent to angle E if CD= 4x+9, DE= 7x-5, CE= 16x-27, find x and the measur
Montano1993 [528]
ANSWER

x = 3
CD= 21 \: units
DE= 16 \: units

CE= 21 \: units



EXPLANATION

It was given that ∆CDE is an isosceles triangle.

The length of the sides are given in terms of x as follows.

CD=4x+9


DE=7x-5


CE=16x-27



It was also given that, angle D is congruent to angle E.


This implies that, side CD and CE are equal.


Thus,

|CD|  =  |CE|
In terms of x, we have;

4x + 9 = 16x - 27


We group like terms to get,

16x - 4x = 9 + 27

12x = 36

Divide both sides by 12 to get,

x =  \frac{36}{12}

\therefore \: x = 3


The length of the sides are;

CD=4(3)+9 = 21 \: units

DE=7(3)-5 = 16 \: units


CE=16(3)-27 = 21 \: units

A store is having a sale on DVDs and CDs. DVDs cost $4 and CDs cost $7. On one day, the store made $204 from DVD and CD sales, a
Gre4nikov [31]
We are given here the individual costs of DVD and CD as well as the total sales and the number of items sold on one day. To solve the number of DVDs and CDs sold each, we devise two independent linear equations:

(1) x + y = 39
(2) 4x + 7y = 204

x- number of DVDs; y - number of CDs

solving, x= 23 DVDs
y = 16 CDs

Find the corresponding effective interest rate for 3% per year compounded continuously?
jeyben [28]

Answer:

3.045%.

Step-by-step explanation:

We are asked to find the corresponding effective interest rate for 3% per year compounded continuously.

We will use effective interest formula to solve our given problem.

r=e^i-1, where,

r = Effective interest rate,

e = Mathematical constant,

r = Interest rate in decimal form.

Let us convert given interest rate in decimal form.

3\%=\frac{3}{100}=0.03

Substitute values:

r=e^{0.03}-1

r=1.030454533953517-1

r=0.030454533953517

r\approx 0.03045

Convert into percentage:

0.03045\times 100\%=3.045\%

Therefore, the corresponding interest rate would be 3.045%.
