good, how are you?

I will show you how to do the first one and you do the rest of them:

13/7 =1.857142...... - 1 =0.857142 x 100 =85.7142% increase.

24/7 =

33/7 =

40/7 =

61/7 =

Counting 26 years from today, the number of days to Dec. 6, 2042 is=9,496 days including leap days.

use the internet

73% → 73/100

.

Use the following facts:

sin(a + b) = sin(a)cos(b) + sin(b)cos(a)

sin(a - b) = sin(a)cos(b) - sin(b)cos(a)

and set a = 0.5x, b = 0.1x

 to show that  sin(0.6x) - sin(0.4x) → 2sin(0.1x)cos(0.5x)

.

Pi is defined as the ratio of the circumference of a circle to its diameter.

Alternative hint:  First multiply through by e^-x then make the substituion z = ye^-x

9/2+15/4+6/5?

\(\large\frac{9}{2}+\frac{15}{4}+\frac{6}{5}\)       least common multiple   \(2^2\times 5=20\)

\(\large\frac{9\times 2\times 5+15\times 5+6\times 2^2}{20}=\frac{189}{20} =9\frac{9}{20} \)

y = 7x - 1 For the equation above, create 1. table of values 2. co-ordinates 3. plot the line      pls  an                                                                                               Which?

Does this come with a diagram.  The description is not clear ://

14!/(2!12!) → 14*13/2 → 7*13 → 91

If I've interpreted the question correctly, then, using L for length and W for width and height, we have:

when you've been cramming for 8 hours...

5/9 * 18 = 10

4/9 * 18 = 8

\(\sqrt{144} = 12\)

what is a scale factor for radius from a 5cm radius to 15cm radius circles

Scale factor for the radius is 3

Scale factor for the area is 3^2=9

Good try guest answerer but

ln(x) + ln(4x) = 2

\(ln(x) + ln(4x) = 2\\ e^{ln(x) + ln(4x) }=e^ 2\\ e^{ln(x) } \textcolor{red}{\times }e^{ ln(4x) }=e^ 2\\ x \textcolor{red}{\times }4x=e^ 2\\ 4x^2=e^ 2\\ etc\)

7x - 1 = 2x + 5

subtract 2x from both sides

then

add 1 to both sides

then you decide what to do.   :)

log4x+log5(x-6)=2

\(x\approx 8.179\)

Here is a graphical solution

x^2=27

\(x^2=27\\ x=\pm\sqrt{27}\\ x=\pm\sqrt{9*3}\\ x=\pm\sqrt{9}\sqrt{3}\\ x=\pm3\sqrt{3}\\\)
