Answer:

1. 108.375 2. 76.765625

Step-by-step explanation:

1. We have the s-value now, which is 4.25.

Plug it in to the equation for surface area:

6*(4.25)^2

6*4.25*4.25

Using a calculator, we get 108.375

2. Plug 4.25 in to the equation for volume:

(4.25)^3

4.25*4.25*4.25

Using a calculator, we get 76.765625

Angles ABC and DBE are vertical angles where m∠ABC = (5x + 5)° and m∠DBE = (6x − 3)°.

Solnce55 [7]

Value of x when angles ABC and DBE are vertical angles where
M_ABC=(5x+ 5)° and m_DBE=(6x-3)° is 8°.
Vertical angles are complementary as there sum is 90°.
As given,
Part A:
Angles ABC and DBE are vertical angles m_ABC=(5x + 5)°
M¿DBE=(6x- 3)°
(5x+ 5\°=(6x - 31
=(6x - 5x)°=(5 +3)°
8°
Part B:
Vertical angles are complementary if there sum is 90°.
Here
m_ABC + m_DBE
5(8)+5 +6(8)-31°
= 90°

Given the system y > -2 x + y < 4

katen-ka-za [31]

1. Points that lie on the intersection area of the inequalities are solutions.

For example (0,2), (-4,4), (2,-1), (-8,0) and all others which lie in this area.

2 Not solutions are points that are on the lines (because we have signs > and <, not ≤ and ≥), or on the areas that are not intercepted. For example, (6,2), (2,2), (2,-4),(-6,-2).
