Answer: The surface area of the cube is 385 mm^2.

When we are finding the surface area of a shape, we need to add up all the areas of each face. In this case, there are 6 faces.

Each face is the shape of square with sides of 8 mm. So the area of each face is 8 x 8 = 64 square mm.

Since we have 6 faces, we will multiply 64 by 6 to get 384 mm^2 in all.

Solve 0= 2t^3-21t^2+ 40t

sukhopar [10]

$0=2t^3-21^2+40t$
switch sides
$2t^3-21t^2+40t=0$
solve factoring
$t(t-8)(2t-5)=0$
using the zero factor principle
$t=0
$
solve
$t-8=0:t=8$
solve
$2t-5=0:t= \frac{5}{2}$
$t=0,t=8,t= \frac{5}{2}$
Hope this helps

serious [3.7K]

Answer:

d. 94

Step-by-step explanation:

If business decreases 10%, it is 100% - 10% = 90% of normal.

If business decreases 30%, it is 100% -30% = 70% of normal.

if business is 94% of normal, it is not between these values, so is not a winter business statistic.

Answer:

Step-by-step explanation:

the height of a right-angled triangle to the Hypotenuse is the square root of the product of the lengths of the 2 segments of the Hypotenuse.

so the square of the height is then the product of the 2 line segments of the Hypotenuse.

therefore

AC² = DC × BC
