7.6/1000000 x 1300 = .00988 liter = 9.88 ml
Given V=3.14r^2h isolate h (step by step)
x+3(x-6)=2x-3
x+3x-18=2x-3
4x-18=2x-3 |-2x
2x-18= -3 |+18
2x = 15 | : 2
x = 7,5
A 4" by 6" by 8" rectangular solid is cut by slicing through the midpoint of three adjacent edges. What is the number of inches in the sum of the lengths of the edges of the tetrahedron that is cut?
I would really appreciate it if you guys could help me out as I am very bad at math!
Say thank you
64 x 2 x sqrt2 = 128 x 1.414 = 181.019
\(\sqrt{2}\) = 1.414213562373095...
1.414213562373095 * 2 = 2.82842712474619
2.82842712474619 * 64 = 181.01933598375616
2) x + y = 120 (1)
x - y = 50 | + y (2)
x = 50 + y
x in (1)
50 + y + y = 120
50 + 2y = 120 | - 50
2y = 70 | : 2
y = 35
y in (1)
x + 35 = 120 | - 35
x = 85
1) 5x - 7 = 3x + 11 | - 3x
2x - 7 = 11 | + 7
2x = 18 | : 2
x = 9
Log(128) / Log(2) =7 NOT 76, so that:
2^7 = 128.
1) 5x - 7 =3x + 7
5x - 3x =7 + 7
2x =14 divide both sides by 2
x = 7
2) a + b =120
a - b =50
a =85, b =35
Definitely 2ml. :)
It's just practise and hard work.Do lots of examples and never be afraid to admit that you don't understand something.A teacher can't help you if you don't tell him/her that you don't understand a particular topic or problem. But most people need to work harder at mathematics than other subjects. It sure shows if you don't. Work hard enough and you can do it - and once you can,it feels pretty good.
1) x/6=6/9 x=6*6/9=4
2) x/2=4/8 x= 2*4/8=1
3) x/54=3/18 x=3*54/8=9
4) x/12=21/4 x=21*12/4=63
5) x/12=4/3 x=4*12/3 =16
6) x/87=5/29 x=5*87/29=15
The rest will come later.
I have no more time.
Wait, is that why it's called the tan graph? Tangent graph?
Find the M is the midpoint of the line segment PQ, what is the coordinates of point Q? P (4, 5), M (-2, -3)
Two cubes of volumes $8 \text{~cm}^3$ and $27 \text{~cm}^3$ are glued together at their faces to form a solid with the smallest possible surface area. What is the number of square centimeters in the surface area of the resulting solid?
5*3 + 1 = n
There really isn't a question posted here..... but 13 less than 37 is 24 .....which is half. Whole would be 48.
1/6
The answer is 2
The answer is 66
11/4 : 1/8 = 11/4 * 8/1 = 88/4 = 22
The answer is 2 and 6/17
