High school math help??????????????????

Twenty-one questions are 19 questions too many to answer.
I suggest that you keep your questions down to 1 or 2 per query.

But I'll help you with the last question:

... C = (5/9) (F-32)
or (F-32) = (9/5) C
or F= (9/5) C + 32

or F= (9/5) (8) + 32
or F= 46.4°

Today, we got a math worksheet. It is all about using Inductive Reasoning to solve problems. I can't seem to figure out three of them and was wondering if any of you could. The patterns are:
18, 46, 94, 63, 52, 61, ____
O, T, T, F, F, S, S, E, N, ____
4, 8, 61, 221, 244, 884, ____

and if you could, can you check to see if this problem is right? (the slashes represent the fractions)
1, 3/2, 9/4, 27/8
For the missing number, i got 243/64

Highschool math, will you help?

you know already that, say for example, sin (⅓ π) = sin (60°) = (√3)/2

So, using the arc-function, or inverse function, we can reverse that... figure out the angle from a ratio:
arcsin [ (√3)/2 ] = 60° = ⅓ π

Thats all we are doing here...
if sin θ = -0.5005 then
arcsin (-0.5005) = ?

Put it in the calculator... an arc-function, or inverse function, is the sin with the -1 exoponent on it, on the calculator.
arcsin (-0.5005) = -30.033°... just larger than -π/6 radians

Highschool math question help please?

Ive been working on these problems for the last 3 days and im still unsure of my answer. Please guys help me!! I will give you 10 points in return just for willing to help me out.Thanks Guys!

A jar contains five blue marbles, six red marbles, and four green marbles. Three marbles are drawn from this jar, and replaced back into the jar after they are drawn. What is the probability you will draw two red marbles and a green marble?

A)161/375
B)14/375
C)16/375
D)21/375

Two balls are to be pulled from a vase that contains 7 red balls, 9 green balls, and 2 black balls. After the first ball is drawn, it is not replaced. What is the probability that two red balls are chosen from the vase?

A)49/51
B)7/54
C)7/18
D)7/51

A sample of 20 children had 4 children with hazel eyes. If there are 750 children in a school, how many should have hazel eyes?

Highschool math question help please?

First:
Probability of one out of 13 heart cards being drawn out of a deck of 52 cards is 13/52 = 1/4
Probability of the coin toss result being tails out of heads and tails = 1/2
Probability of both happening is 1/4 * 1/2 = 1/8 = 0.125
D)0.125

Second:
Probability of first parakeet being green is 12/(25+12+10) = 12/47
Probability of second being one out of 11 green parakeets left, from a total of 46 parakeets left = 11/46
Probability of both being green = 12/47 * 11/46 = 0.0610545
D)0.0611

Third:
The third seems to be a question of unitary method, but the answer by that method comes out as 35.4, which may indicate C)36 as the answer but I am not sure. If that answer is correct, here is how you do it.
Cars with grey interiors in a sample of 100 = 59
Cars with grey interiors in a hypothetical sample of 1 car = 59/100
Cars with grey interiors in a sample of 60 = 59/100 * 60 = 35.4

Please help with high school math problem!!?

The speed going was plane's speed + wind's speed = 1740/6

The speed going back was plane's speed - wind's speed = 570/3

so (r+w) = 1740/6
(r-w) = 570/3

or, multiplying to rempve the fractions,
6(r + w) = 1740
3(r - w) = 570

**************************************...
To solve:
1740/6 = 290, and 570/3 = 190. Thats a diference of 100 km an hour, half going and half coming, so the differenc is 50 mph. The wind's speed is 50 kmph

That makes the plane's speed
290 - 50 = 240, or 190 + 50 = 240. Same answer either way.

If you need an equation,

x + y = 290
x - y = 190

2x = 480
x = 240 (plane's speed)
then substitue that back in to either equation and get
y = 50 (wind's speed)

Hope that helps, and good luck!
