-2(11-12x) = -4(1-6x) simplify
-22 + 24x = - 4 + 24x subtract 24x from both sides
-22 = -4 this is never true....so......this has no solution....
Add up the ratio of professors and lecturers together: 5 + 14 =19
5/19 x 228 =60 professors
14/19 x 228 =168 lecturers.
Thanks cphill
Btw, ((1372000000000000000*pi)/3) = 1436755040241732107.723582240619826, so about 1436755040241732107.72 km3
If this is :
(1/2) (11 + 18) =
(1/2)(29) = 14.5
If it's
(1/2)11 + 18 =
5.5 + 18 = 23.5
\(V={4\over3}\pi*r^3\)
So, substitute the given radius.
V=4/3pi*700000^3 = V=((1372000000000000000*pi)/3)
3.14159 but it gos on forever.
Vcone = [ pi * (d/2)^2 * h ] / 3 = pi * (3/2)^2 * 5 / 3 = about 11.78 in^3
WAIT but where did u get the 19 from
Vsphere = (4/3)pi*(9.5)^3 = about 3591.36 cubic inches
168 lecturers and 60 professors
Your welcome :)
The 228 is divided into 19 parts, each consisting of 5 professors and 14 lecturers....so....
Professors = (5/19) * 228 = 60
And the Lecturers must = 228 - 60 = 168
(9/5)C + 32 is the "formula" that converts the Centigrade scale to the Fahrenheit scale
Mathaholic's answer is exactly correct....!!!!
Notice that the two quantities sum to 43,812
So...to apportion the cost between the two quantites
(29208 / 43812) * 12190 = $8126.67 = Qty 1's portion
And Qty 2 will just be 12190 - 8126.67 = $4063.33 = Qty 2's portion
The area of a circle is:
pi * radius^2
To get the radius you halve the diameter to get 10.5
You square it and times it by pi to get:
346.3605901
6 + 2/3 = 20/3
So
700 / ( 20/3) =
(700/20) * 3 =
35 * 3 = 105 m
That is very true. Thank you. I think that my teacher would want exact answers if anything, although, but thank you for the help anyway!
You use the indices rule where you add the powers when you multiply so you get x^4+x^2=x^6
If you only have three angles then you know the shape the triangle will take but you will not know the exact length of a side.
You could have a triangle with all those angles and sides of 34, 23,78 and you could also have another triangle with the same angles and sides of 68,46,156.
Thank you! I realized that you are allowed to record the answer as "can not be determined". I guess that fits its description. Thanks again!!!
(78+x)-2574=420
Since there is no number next to the brackets we assume it is one and multiply it out as such.
Therefore we get:
78+x-2574=420
Now to simplify:
x-2096=420
x+420+2096
x=2516
:) :) :)
You will not be able to find the sides given just the angles. The reason for this is that there are many similar right triangles with the same given angles......but........all of them will have differing sides......so.....we need to know the length of at least one side of this triangle in order to find the others
any webpage that can help me on pre-algebra,but a GOOD one
