How do I figure out my overall SAT score?

I have the breakdown scores for my SAT's (ex. critical reading:600, math:530, writing: 560) but I have no idea how to determine the larger number (ex. 1750)How do I figure out my overall SAT score?
Add them.





600+530+560 = 1690How do I figure out my overall SAT score?
You just add them together.
Yeah just add them..u did good though..thats not bad at all..keep the good work up..

How would I figure out a grade point average from college?

Let's say I have this percentage:





Reading: 75 C


English: 75 C


Speech: 75 C


First Aid: 80 B


Math: 70 D





How would I figure this out?How would I figure out a grade point average from college?
It depends how many credits the classes are worth.





A 4 credit class is going to impact your gpa more than a 1 credit class.





This is how most colleges calculate GPA's





A = 4


B = 3


C = 2


D = 1


F = 0








Take the number you got according to your grade then multiply it by the number of credits the class was worth.





For example, a B in a 4 credit class would give you 12points





Find out how many points you get from each class and add them all together.





Take that number and divide by the total number of credits you took this semester.





If all your points added up to 36 and you took 10 credits you would have a 3.6 GPA





I hope you followed that little confusing.How would I figure out a grade point average from college?
A=4


B=3


C=2


D=1


F=0





Add up the total and divide by the number of classes. So that's 2+2+2+3+1=10. Then divide by number of classes, that's 5. 10/5= 2. Which means you got exactly a 2.0





If your in college, you should really know how to do this!
I guess this is the same as average so I'll show you:





You add them all up: 75 + 75 + 75 + 80 + 70 = 375, and then they look where your number falls. Maybe a 3.0 or 3.5 its really confusing
You add them all up and then you divide it by the number of items you are adding


add em up .. you get 375 divided by 5 grades your average is 75

How can I figure out the 2D surface with dimensions from a 3D cone?

I have the following dimensions for a 3D cone: top ID: 12';, Bottom ID: 2';, Sides of cone: 6';. I want to make a cone out of sheet metal so I'm trying to figure out how much I will need. I know the circumferences of the top and bottom (37.699';, 6.283'; respectively), but I cannot figure out how exactly to curve the tops and bottoms.How can I figure out the 2D surface with dimensions from a 3D cone?
I'm thinking it would be a trapizoid? (isnt that where 1 pair of sides is parallel, and other pair isnt?).


So, the bottom base is 37.699, top base is 6.283 which would be parallel to each other.


And the other sides, which are slanting toward each other,


are 6 each.

How do I figure MPH and top speed?

My kids are making some CO2 cars. I want to work a little math in the project soooo what formulas would I use to figure average MPH and the top speed the car obtained (I'll suppose that the car was still accelerating at the time the race was over). The car traveled 60 feet in 1.668 seconds.How do I figure MPH and top speed?
MPH (There are 5280 ft in a mile) -


Car = 60 feet in 1.668 seconds.


First you turn the feet into miles. 60 feet = (60/5280) miles = because the car went 60ft out of 5280ft (a mile.)


Then you turn the seconds into 1 hour. What number times 1.668 seconds = an hour? 1 hour = 60 minutes = 3600 seconds. 3600/1.668 = about 2,158.





Multiply both sides of 6/528 miles per 1.668 seconds


by what will make 1.668 seconds and hour (2,158) to get.....about.....





24.5 miles per hour.








Now, for top speed.





V = 1/2 A * T^2


The above is a physics formula relating Velocity (speed), Acceleration, and Time.





You're trying to find V right now.


If you assume the car was going fastest at the end of the race, T = 1.668 seconds. So you have your T. But now you need the acceleration of the car, which you most likely can't get unfortunateley. Your best bet is to tell your kids the acceleration and THEN they could use the formula.How do I figure MPH and top speed?
On a simpler note, assuming constant acceleration,





Vav = D/t = 60/1.668 = 35.97 ft/s 鈭?(30/44) = 24.5 mph





Vmax = 2*Vav = 49 mph





If it's of any interest, the acceleration a = 2D/t虏 = 43.13 ft/s虏








The last formula given by Dadgwelen is for distance, not velocity..........

  • How can you figure out the linear equation when only given 1 point and the slope, for example (1,3), m=4?

    Please be detailed. I am not looking for answers to my homework but an understanding!

    dell_email Yahoo IDHow can you figure out the linear equation when only given 1 point and the slope, for example (1,3), m=4?
    A straight line (linear equation) requires either...


    a) two points (and then join them up), or


    b) one point and an indication of the direction (which is the gradient).





    The equation of a line is y = mx + b where,


    y is the y-coordinate


    x is the x-coordinate


    m is the gradient


    b is the y-intercept location





    Your question gives 3 out of 4 of these values.


    The point (1,3) has the values x = 1, y = 3


    The gradient has the value m = 4


    By substitution then,


    y = mx + b


    3 = 4 x 1 + b


    3 = 4 + b


    -1 = b


    Therefore, the equation of the line is


    y = 4x - 1





    Another example, find the linear equation given the point (4, 3) and gradient (m) = -1


    y = mx + b


    x = 4, y = 3, m = -1, find b


    3 = -1 x 4 + b


    3 = -4 + b


    7 = b


    Therefore, the equation is


    y = -1x + 7, or


    y = -x + 7





    If you are given two points, say (2, 5) and (3, 4), you could perform the following:


    a) find the gradient (m = (y2 - y1) / (x2 - x1)) then use 1 point to find the y-intercept (b)


    b) use the point-gradient formula: y - y1 = m(x - x1)





    Trust this helps.How can you figure out the linear equation when only given 1 point and the slope, for example (1,3), m=4?
    y-y1=m(x-x1) is point-slope form. To get it into the form you probably want:


    y=mx-m(x1)+y1


    y=4x-4*1+3


    y=4x-1
    Let (x1, y1) = (1, 3) be the point on the line and the slope is m = 4.


    The, the equation of the line given one point and the slope is given by: y - y1 = m(x - x1)


    =%26gt; y - 3 = 4(x - 1)


    =%26gt; y - 3 = 4x - 4


    =%26gt; y - 3 + 3 = 4x - 4 + 3


    =%26gt; y = 4x - 1


    =%26gt; 4x - y - 1 = 0 is the required line
    Use the point-slope formula.





    y-y1=m(x-x1) where m=slope, and x1 and y1 are the given point.





    y-3=4(x-1)


    y=4x-4+3


    y=4x-1

    Where can I purchase a english mouth / ';living mouth'; ventriloquist figure?

    I have searched the search engines, but can't seem to find a vent figure maker that makes the leather style mouths. I have contacted some' and they have either, not responded or simply do not make them. Does anyone know where I can obtain one of these figures? I know Craig Lovik made them here in the United States in the '80's but I don't believe he is still in business.Where can I purchase a english mouth / ';living mouth'; ventriloquist figure?
    His son is still making them:
