Answer:
The effect of doubling all the dimensions of a triangular pyramid will have on the volume of the pyramid is to increase it by 8 times.
Step-by-step explanation:
i) volume of triangular pyramid = 
Area height
= (Base of triangle perpendicular height of triangle) height
ii) if we double all the dimensions then the three variables((Base of triangle, perpendicular height of triangle, height of pyramid) will be doubled
and the volume of the new pyramid will be 8 times that of the original one.
Step-by-step explanation:
Let the coordinates of point b be (x,y).
Given the coordinates of a (-7,5) and c(5,-1)
Now according to question
ab = 5bc
using distance formula
Solving we can get
'
However, we do need either x or y coordinate of point b to find the other.
If Jake ate 1/6 of the cookies at the party and we know he ate 5 cookies. We must find out how many cookies there are in all.
Now x here represents how many total cookies are at the party.
We have to simply find out what 1 was multiplied by to get 5.
We can do this by dividing.
5 ÷ 1 = 5
So the numerators (the top numbers) were multiplied by 5. We can do the same to the denominators (the bottom numbers) to get the total number of cookies.
Lets multiply.
6 x 5 = 30
So the total number of cookies is 30
Good Luck! <3
Answer:
14
Step-by-step explanation:
4x-29+ 5x-9= 7x -10
4x+5x-29-9=7x-10
9x-38=7x-10
9x-7x=38-10
2x=28
x=28/2
x=14
1/10 is equal to 0.10. Multiply their total tables (200) by the percent (10% aka 0.10), and you get 20. Hope this helps.
