Gwen takes out a loan of $400 to pay for an online course. Flat rate interest is charged at 8% p.a

puteri [66]

We know, 1 year = 12 month.

So, 3 month = 3/12 = 0.25 year.

Now, principle amount, P = $400 .

Rate is, r = 8% = 0.08

Time period, t = 0.25 year.

Now, Interest is given by :

I = P × r × t

I = $( 400 × 0.08 × 0.25 )

I = $8

Therefore, she will pay $8 interest in total.

Which number is greatest? 2.89 times 10 Superscript negative 8 1.997 times 10 Superscript 2 8.9 times 10 Superscript negative 6

love history [14]

<h3> The greatest number is $1.997 \times 10^2$ </h3>

Solution:

Given that the numbers are:

$2.89 \times 10^{-8}\\\\1.997 \times 10^2\\\\8.9 \times 10^{-6}\\\\5 \times 10^{-6}$

We have to find the number that is greatest

Convert the numbers to decimal

$2.89 \times 10^{-8} = 2.89 \times \frac{1}{10^8} =0.0000000289$

$1.997 \times 10^2 = 199.7$

$8.9\times 10^{-6}=8.9\times \frac{1}{10^6}=0.0000089$

$5\times 10^{-6}=5\times \frac{1}{10^6}=0.000005$

We can clearly see that, 199.7 is greatest number

Thus the greatest number is $1.997 \times 10^2$

In triangle ABC mzA -45, mzB = 40", and a = 7. Which equation should you solve to find b?

yaroslaw [1]

Answer:

Option A. $\frac{sin(45\°)}{7}=\frac{sin(40\°)}{b}$

Step-by-step explanation:

we know that

Applying the law of sines in the triangle ABC

$\frac{sin(A)}{a}=\frac{sin(B)}{b}$

substitute the given values

$\frac{sin(45\°)}{7}=\frac{sin(40\°)}{b}$

$b=\frac{7}{sin(45\°)}sin(40\°)\\\\b=6.4\ units$
