Answer:
D
Step-by-step explanation:
When calculating the area of a parallelogram, use the formula A = l*h where length is the longest length and h is the perpendicular height of the shape. For this parallelogram, substitute l = 14 and h = 8.
A = l*w = 14*8 = 112
Answer: Greater of equal sign
Step-by-step explanation:
5+10+x is greater than or equal to 30 ( use the greater of equal to sign)
Answer:
8
Step-by-step explanation:
Sea el número x El cuadrado será x ^ 2
Entonces la suma será; x ^ 2 + x = 72 x ^ 2 + x-72 = 0
x ^ 2 + 9x-8x-72 = 0
x (x + 9) -8 (x + 9) = 0
(x + 9) (x-8) x = 8 o -9
Como solo estamos considerando números naturales, la respuesta correcta es 8
321,568,794 is not ten times the value 469751803
Considering the cube with dimensions given in this problem, we have that:
a) The volume after t hours is given by: V(t) = (0.5t + 4)³.
b) The surface area after t hours is given by: A(t) = 6(0.5t + 4)².
c) The surface area will equal 294 m² after 6 hours.
<h3>What are the volume and the surface area of a cube</h3>
Considering a cube of side length s, we have that:
For this problem, the side length after t hours is given by:
s(t) = 0.5t + 4.
Hence, the volume after t hours is given by:
V(t) = (0.5t + 4)³.
Also applying the formula, the surface area after t hours is given by:
A(t) = 6(0.5t + 4)².
The surface area will be equals to 294 m² when:
A(t) = 294.
Hence:
6(0.5t + 4)² = 294
(0.5t + 4)² = 294/6
(0.5t + 4)² = 49.
Applying the square root to both sides:
0.5t + 4 = 7
0.5t = 3
t = 6 hours.
