You both need to include angles and inverse notation!

How about 10, because the ratio 5: 1 is the same 50:10

180(1.25)  = 225 cars 

thank you

If the ratio of candy to bags was 5:1  we must have 5 times as many pieces of candy as bags

So ..... 50/5 =  we must have 10 bags

Well, how about (14-10 t)

A full price ticket for a college basketball game costs $2.50, and a student ticket costs $1.75. If 585 tickets were sold and the total receipts were $1,217.25, how many tickets were student tickets?

Let's see how to get the answer....step-by-step.....

Let x be the number of student tickets and (585-x ) the number of full-price tickets....and we know that......

1.75x + 2.50 (585 - x)  =  1217.25   simplify

1.75x  +  1462.50 - 2.50x =  1217.25

-.75x + 1462.50  = 1217.25      subtract 1462.50 from both sides

-.75 x  = -245.25     divide both sides by -.75x

x  = 327   ......and this is the number of student tickets

And (585 - 327) = 258   and this is the number of full-price tickets

How about 52.00 x .18=$9.36

Well, 15% means you divide 15 by 100=15/100=.15

So, you just multiply his meal by .15

$15.40 x .15=$2.31

Thanks CPhill :)

How about 2/3

?How do you find percentage?

Well it depends on numbers,

Suppose you have numbers like 3 and 12. If I asked you what percntage of 12 is 3?

All you would do is divide 3/12 x 100=.25 x100=25%. And that's how find percentages.

3 / (√a+8)    nultiply the top and bottom by  (√a - 8)   and we have

[3   (√a - 8)] / [  (√a+8)  (√a-8)  ]   =

[3√a  - 24]  / [ a - 64 ]

Thank You

if sin=4/5, find csc

Well, sin(4/5)=.80, csc=1/sine=1 1/4

Evaluate m² + mtp if m = 3, t = 4, and p = 7.

(3)² + (3)(4)(7)  =

9 + 12*7  =

9 + 84 =

93

I'm assuming that the garden is in the shape of a square [ if not, there might be infinite possibilities]

So  the area of a square is just the side squared   and we have

side² = 225      take the square root of both sides

side = sqrt (225)  = 15 ft

So each side  is 15ft   and there are 4 of them....so we need 15 x 4  = 60 ft of fencing 

If his garden is a perfect square(with all sides equal), then we just take the sq root of the total area of 225 sq.feet=15 feet, so the total length of fence needed would be 15 x 4=60 feet

We can use the tangent inverse to find this:

tan^-1(200/80) = about 68.2°

Find the angle of elevation of the sun if a tower 200 meters tall cast a shadow 80 meters long,

Well, use the tangent function:

tan=Op. Side/ Adj. Side

tan(x)=200/80=2.5, Now will find the inverse of tangent or arctangent of 2.5=68.2 degrees, which is your angle.

thank u

-3/4x >3     multiply both sides by -4/3 and reverse the inequality sign  [since we're multiplying by a negative]

x <  -4

14u + 9 – 10u > 21   simplify

4u + 9  >  21     subtract 9 from both sides

4u >   12     divide both sides by 4

u > 3

Anon, CPhill know how to think.

Wolframaplha is a computer it do not know how to think.

I was just thinking anon you are like wolframalpha you do not know how to think either so maybe I need to answer your question. The answers are not equivalent
