Answer:

31

Step-by-step explanation:

In circle S: XB and XD are tangents at B and D

then SB perpendicular to AX and SD perpendicular to XC

In triangle SDX:  SD = 12 and SX =20 by using Pythagoras Theorem

XD=\sqrt{20^{2} -12^{2} }=16

XD = XB  tangents to circle S from point X

XA = XC tangents to circle R from point X

then BA = DC = 15

then XC = XD + DC = 16 + 15 = 31

A building society offers a rate of 11% per annum simple interest. Beth-Ann deposit 24000 in the society for 15 months. Calculat
Nostrana [21]

Answer:

The amount of money due to Beth-Ann at the end of this period​ is $27, 300.

Step-by-step explanation:

The amount at the end of a period, when simple interest is being charged is:

Amount (A) = Principal (P) + Interest (I)

Here interest is computed using the formula:

I=P\times R\times T

It is provided that:

P = 24,000

R = 11%

T = 15 months = 1.25 years

Compute the Interest as follows:

I=P\times R\times T

  =24000\times 0.11\times 1.25\\=3300

The interest earned is, <em>I</em> = $3,300.

Compute the amount of money due to Beth-Ann at the end of this period​ as follows:

A=P+I

   =24000+3300\\=27300

Thus, the amount of money due to Beth-Ann at the end of this period​ is $27, 300.

Taylor states that 2,800,000 in scientific notation is 2.8 x 10 -6 because the number has six places to the right of the 2. Is T
soldier1979 [14.2K]

Scientific Notation is the way of <u>writing a number or expressing them</u> in a <u>shorter or more compact way.</u>

No, <u>Taylor's resoning is incorrect</u> because  2,800,000 = 2.8  * 10^{6}

From the question, we are given:

2,800,000 .

2,800,000 in scientific notation is  2.8  * 10^{6}.  

The reason the power is not to the negative 6 is that we are moving from the right-hand side to the left-hand side 6 times.

Therefore, <u>Taylor's reasoning is incorrect. </u>
