How do you find the surface area of a regular triangular prism
Dmitry [639]
So a triangular prisim is like a triangle stacked on top of x number of identical triangles making a height, like a piece of paper made into a stack

so
basically find the area of each side and add

look at diagram/attachment
find area of triangle
1/2 b times h= area of 1 triangular face

multiply by 2 because 2 sides so 1/2 times 2 b times h=b times h

then 3 other sides
find area of each side and add
areas=(H times B)+(H times c)+(H times a)

so SA=(b times H)+(H times B)+(H times c)+(H times a)

If a rock falls from a height of 40 meters on Earth, the height H (in meters) after x seconds is approximately
Julli [10]
Once the rock hits the ground, we know that its height will be equal to 0m
because of this, we can replace H(x) with 0
40 - 4.9 {x}^{2}  = 0
now all we have to do is get x by itself
so..
4.9 {x}^{2}  = 40
then
{x}^{2}  = 40 \div 4.9
{x}^{2}  = 8.1632...
now take the square root of each side
x = 2.857...
2.857 seconds (rounded to the third decimal)

Solve the proportional equation 2/3 = x/15
dimulka [17.4K]
  2            x
 -----  =  ------
  3           15

cross multiply
(3)(x) = (15)(2)
3x = 30
x = 30/3
x = 10

so 2/3 = 10/15.......notice how these are equivalent fractions....that is because proportions are nothing but equivalent fractions

Solve for y.<br><br> −2y+7=−5
kakasveta [241]

Answer:

Ur right! The answer is y = 6

Step-by-step explanation:

So, we have the equation of -2y + 7 = -5.

So, if y = 6, it would now be (-2 * 6) + 7 = -5.

Now, lets solve:

(-2 * 6) + 7

-12 + 7

= -5

So, ur answer is A. y = 6.

Hope this helps :DD
