Answer:
61°
Step-by-step explanation:
Alright so the total amount of degrees in a 5-sided shape or pentagon is 540°. Since we have four of the five total angles, we can solve for the last one.
Sum of all the degrees of all five angles = 540°
The variable x is representing our last unknown degree.
90° + 107° + 144° + 138° + x° = 540°
Add up all the known degrees and solve for x.
479° + x° = 540°
Subtract 479 on both sides so that we can isolate x.
479° + x° - 479° = 540° - 479°
x° = 61°
So our final answer is 61°
Answer: 27 times bigger.
Step-by-step explanation:
You need to use the following formula to find the volume of a Square pyramid:

Where "s" is the edge of a side of the square base and "h" is the height of the pyramid.
Knowing that:

You can find the volume of the Pyramid A and the volume of the Pyramid B:

Finally divide the volume of the Pyramid B and the volume of the Pyramid A, in order to find how many times bigger than the Pyramid A is the Pyramid B.
You get:

For convenience sake, I will let 
First, we evaluate the function at the endpoints of the interval.

Then, we need to find the critical points.
We can start by taking the derivative using the power rule.

Setting this equal to 0,

Since
, we can divide both sides by
.


So, the absolute minimum is
and the absolute minima are 
Hola,
no habla espanol muy bueno pero voy a tratar a ayudarlo. podemos simplificar 6/15; simplemente divide por 3. el resultado es 2/5, no 3/5. entonces, 6/15 no es equivelente al 3/5.
Answer:
You can use the quadratic formula
Step-by-step explanation:
X= -b +/- √b^2-4(a)(c)÷ 2(a)
Substitute and simplify to find x
