Answer:
There is a 3 in 9 chance
Step-by-step explanation:
First we find the volume of the triangular prism.
We find the area of the triangle, then we multiply that by the height.
So 7*6/2= 42/2=21
21*10= 210
Then if all the dimensions add another foot on to them then you get: 7, 8, and 11.
Then you do the same thing to find the area of this rectangular prism.
7*8/2=56/2=28
28*11= 308
Now, we calculate the growth from 210 to 308 in this proportion: 308/210=x/100
Solving it we get (cross multiplying):
210x=30800
x=146 2/3 or 146.66 percent increase.
I hope this helps!
Answer:
Step-by-step explanation:
for missing angle of triangle ABC
let the missing angle be y
31+111+x=180(sum of interior angle of a triangle is 180 degree)
142+y=180
y=180-142
y=38 degree
x=y(being alternate angles)
x=38 degree
Answer:
simplify = - 4 x -2 factored = 2 (-2x - 1)
