Answer:
Step-by-step explanation:
We can first solve for the face diagonal. That is 
. Notice this will form a right triangle with the vertical side. We get that the face diagonal = 
. Now, we can use Pythagorean theorem again to get the straw length:
where s = the straw length.
We can solve that s = 
Answer:
5.
x + 2(x + 1) = 8 --> x = 2
y = 2 + 1 = 3
7.
3(9 + 2y) + 5y = 20 --> y = -7/11
x = 9 + 2(-7/11) = 85/11
9.
3(-1 - 2y) + 5y = -1 --> y = -2
x = -1 - 2(-2) = 3
Answer:
8/81
Step-by-step explanation:
It's most efficient to simplify the quotient algebraically before inserting the values of the variables x and y.
The given expression reduces to x³ / y^4.
Substituting 2 for x and 3 for y, we get:
(2)³ 8
--------- = ---------- (Agrees with first given possible answer)
(3)^4 81
3x^2 * 4x^3 = 12x^5
