Answer:

86.64cm^2 (cm squared)

Step-by-step explanation:

So! This is a cube, a 6-sided shape. All the side lengths will be equal, which makes it really easy to calculate the surface area.

Since you calculate surface area by length x width, you do that once and then multiply it by six to find the total surface area.

So it'd be 3.8cm x 3.8cm = 14.44cm

and then 14.44 cm x 6 = 86.64cm^2, or cm squared.

Which of the following shows the length of the third side, in inches, of the triangle below? (1 point)
GrogVix [38]

Answer:

2, sqrt of 7633

Step-by-step explanation:

for now, we'll leave the 3rd side as x

y using the Pythagorean theorem, we can conclude that (1) 48^2+x^2=73^2 or (2) 48^2+73^2=x^2.

1. If we conclude the x isn't the longest, the x would be 3025 which is the sqrt of 55, now is invalid because the 2 smallest sides can't be more than the longest side when they add up 55+48>73 so that is invalid

2. Then, it leaves us with only 1 choice left! concluding that the 3rd side is the longest. Which the answer is sqrt of 7633

Using  S = ut + 1/2gt²,   from rest, u = 0

S = 1/2gt²,               g ≈ 9.8 m/s²

S = <span>1/2 *9.8*3²

</span>S = 0.5<span> *9.8*3*3 
</span>
<span>S ≈ 44.1 m</span>

Hey!

Solution:

I would assume that the iron intake is combined between breakfast and lunch. So 8.25mg is too meals worth of iron. So all we have to do is subtract.

15 - 8.25 = 6.75

Answer:

6.75mg are still needed for his daily intake.
