How do i do this math problem?
F = force r = radius s = speed w = weight k constant of variation 1) orce needed to stop a car from skidding varies inversely as the radius F inversely as r mathematically F ∞ 1/r -------------------------------1 2)jointly as the weight of the car F ∞ w ------------------------------------2 and the square of the speed F ∞ s^2 ---------------------------------3 from 1 ,2 and 3 F ∞ ws^2 /r F = kws^2/r F = 242, w = 2000 r = 500 s = 30 242 = k* 2000*30*30 /500 k = 0.067 F = ? , r = 750 s = 50 F = 0.067 * 2000*50*50 /750 = 448 pounds
How do you do this math problem?
yes....you should make it slope-intercept form that is , y= mx +c, where m is the slope and c is the y-intercept 6x + 2y = 40 you have to eliminate 6x from the left side, in order to isolate y on the left side for that subtract 6x from both sides.... ==> 2y = 40 - 6x Now divide 2 on both sides ==> 2y/2 = 40/2 - 6x/2 ==> y = 20 - 3x now re arrange the expression in the form, y= mx + c ==> y = -3x + 20, which is of the form, y= mx + c so here slope = -3
How do I do this math problem?
Let h represent hot chocolate and c represent coffee so we know that all the cups of hot chocolate that was sold and all the cups of coffee that was sold will equal 294 cup, this gives us h+c=294 which can be rearranged to c=294-h now we have to add prices so since it is cents we will use decimals and put the price of the hot chocolate infront of h and the same for coffee .75h+.5c=199.75 now we plug them in (this assumes you know .75h+.5(294-h)=199.75 distributive property) .75h+147-.5h=199.75 .25h=52.75 h=211 sub h=211 into h+c=294 211+c=294 c=83 therefore there were 83 cups of coffee sold and 211 cups of hot chocolate sold Hope this helps!

Multiply 7/8 by 2/3 and then reduce to a common fraction. Good luck
HELP! how do i do this math problem?
This is really simple. If the base is an equilateral triangle, 3 in on each side, then you find the surface area for that, which is 4.5 inches, cause A=1/2bh. You must find the base first.Then, you find the surface area for each side. if the slant height is 4.5 and the side is 3( cause the base is equalateral, each side is 3 on the bottom), you do (4.5*3)/2, which is 6.75. you multiply that by 3 (cause it's a prism, each side is the same) and you get 20.25. YOu take that and add 4.5 and you get 24.75. I don't know why you need pi in it, and I don't think the answer is 24.1, unless i read the prob wrong or I calculated something wrong. Whatev.
Can there be more than one right answer on a math problem?
Though I have a math degree, I’m not the best to answer this as I’m certainly not a math expert. As far as I know, there is only one “correct” answer (OK, there may be an infinite number of correct answers but all mathematicians will arrive at the same set) in a purely mathematical sense but where there is great divergence is in how we treat this one answer. For example, …Many risky sports are really “expected value” propositions though they often aren’t thought of in that sense. You, as the athlete, assess your probability of successfully completing the activity, then weight it against the upside and downside rewards. Uli Emanuele’s winged suit flight pretty well illustrateshow two people with the same skill level could do the math on expected value and even with the same inputs, get different outputs. I don’t know what he thought his chances were but let’s just assume 99% success rate. Complete it, you’re the first to do this particular feat, you get it off your bucket list, you get a youtube video with 8.5M hits, you become a legend in your sport, and possibly more. And the 1% downside? You literally become a splot on a rock. If I had exactly the same skills as Uli, that 1% would dominate my decision. I’d assign a value of about minus infinity to it and would sit around the computer and watch Uli’s amazing flight. He clearly understood the consequences of a fail but either he didn’t assign the same consequences to death that I would or he valued the upside (times 99%) more than the 1% risk of becoming a smear.Bottom line for this question is I believe mathematics is only going to give one purely mathematical outcome but when exposed to the real world, this outcome may not appear the same to different people.

Express each ratio as a unit rate. Round to the nearest tenth or nearest cent, if necessary. 1. $4.60 for 5 cans of soup 2. 652 miles in 9 days 3. $51 for a box of 71 tiles please tell me how to do them!!!! and the answer pleez!!!!!!!!!!!
Why do I always get math problems wrong?
Mathmatical problems comes with very strong logic and earnest patience and carefulness. Lack of any one of these three factors may cause errors when you deal with some tough questions.Most of people are careless when they do mathmatical calculating even in some very easy counting case. Therefore, if you do bad in one of those three abilities, pay more time on that and you will find after long-lasting practice, some hard problems may seem easier than what you thought.
