1 regular(normal) year =365 days

15 X 365 =5,475 Number of days in 15 regular years.

25,000 X 8.5/100=$2,125 Simple interest for 1 year

$2,125 X 2.5 years=$5,312.5 Simple interest for 2.5 years

$25,000 + $5,312.50=$30,312.50 Total owed after 2.5 years.

Solve for x:

0.343338 x = 7

Divide both sides of 0.343338 x = 7 by 0.343338:

(0.343338 x)/0.343338 = 7/0.343338

0.343338/0.343338 = 1:

x = 7/0.343338

7/0.343338 = 20.3881:

Answer: |x = 20.3881

If you mean, how many combinations of 3 people can be shosen from 8 then the answer is  8C3

nCr(8,3) = 56

tan(elevation) = height/distance

tan(27°) = height/distance                     (1)

tan(20°) = height/(distance+20)            (2)

From (1) we have distance = height/tan(27°).  Put this into (2):

tan(20°) = height/(height/tan(27°)+20)  so  

tan(20°)*(height/tan(27°) + 20) = height  or

height*tan(20°)/tan(27°) + 20tan(20°) = height   or

height(1 - tan(20°)/tan(27°)) = 20tan(20°)  so

height = 20tan(20°)/(1 - tan(20°)/tan(27°))

You can do the number crunching!

3 - 3*6 + 2 → 3 - 18 + 2  → -15 + 2  → -13

The answer is -13 bully guest

Guests are the best part of this site

your not bully guest tho so its fine, if your a member with the name of bully guest only

I don't think fellow guests are discriminating deliberately they just want help and related math problems. You are probably secretly a member.

6+7x(3-2+2)=-39

6+7x(3)

= 6+  21

= 27

No it is definitely not -39

Have I misunderstood your question?

need more info sorry

Hi Asinus and guest,

Lets look at this.

2/sqrt(5) X sqrt(20) X (8/sqrt(80) I don't understand this question, please answer thank you! :)

\(\frac{2}{\sqrt5} \times\sqrt{20} \times \frac{8}{\sqrt{80}}\\ =\frac{2}{\sqrt5} \times\sqrt{4*5} \times \frac{8}{\sqrt{16*5}}\\ =\frac{2}{\sqrt5} \times \frac{2\sqrt{5}}{1} \times \frac{8}{4\sqrt{5}}\\ =\frac{2}{\sqrt5} \times \frac{2\sqrt{5}}{1} \times \frac{2}{\sqrt{5}}\\ =\frac{2}{1} \times \frac{2*1}{1} \times \frac{2}{\sqrt{5}}\\ = \frac{8}{\sqrt{5}}\\ = \frac{8}{\sqrt{5}}\times \frac{\sqrt5}{\sqrt5}\\ = \frac{8\sqrt5}{5}\\\)

Hello Guests.

(2/sqrt(5) X sqrt(20) X (8/sqrt(80) I don't understand this question, please answer thank you! :)

Since twice the clip without parenthesis.
I try it this way.

With computer is:

(2 / √5) * √20 * (8 /√80) = 2 * 8 * √(20 / (5 * 80)) = 16 * √0.05 = 3.5777

With great doubt!

Greeting asinus :- )

That was beautiful!

Simply divide both numerator and denominator by 3 to get 1/75

.

11% of ($469300 - $440000) is $(11/100)*29300 = $3223

Total income for the year is $22400 + $3223 = $25623

There are 26 fortnights in a year so average fortnightly pay is $25623/26 = $985.50

.

Let t be initial number of $2 notes and n be initial number of $10 notes.

2t + 10n = 1284       (1)

8 pieces of $10 notes are equivalent to 40 pieces of $2 notes, so:

t+40 = n - 8             (2)

Rearramge (2) to get:   n = t + 48.  Put this into (1):

2t +10(t + 48) = 1284

12t + 480 = 1284

12t = 804

t = 804/12   or  t = 67

So there were 67 $2 notes initially.

She's not going to leave the forum forever, she's going to take a break and I'm feeling like doing the same. She's thinking about 2 weeks, I might wait a bit less, but still take time off. Last night was stressful, and I mean stressful.

I was seriously stressed when I posted that. And yes, I would leave for BS-S ppl, they waste my time. My time is extremely precious, so I prefer not,to waste it on dumbshit ppl. :)
