Answer:

22.5 lbs

Step-by-step explanation:

First you find the cubic feet. That is the volume of the object which is length*width*height.

In your example, they are using inches. So you have to convert all units to feet. That would be 0.5 inches, 0.5 inches, and 5/3 inches. The volume would be 0.5*0.5*5/3 which is about 5/12 cubic feet

You then take that 5/12 cubic feet and multiply it by the 54 lbs/cubic foot. The answer would be 22.5 lbs

How do I do this problem??

Crank

Expanding 8x^3, we multiply 8*8 and x^3 by x^3 to get 64x^6. Since we know that the cube root of 64 is 4, we can separate that. Next, since you add exponents while multiplying, 6/3 is the exponent for the cube root of x^6=x^2. Therefore, your answer is 4x^2

PLEASEEEE HELPPPPP MEEEEEE!!!!<br> Find h in the diagrams below.

Leno4ka [110]

Answer:

9.6
11.2

Step-by-step explanation:

It is useful to label the diagram so we can talk about the parts. (See the attachment.)

AB and CD are parallel lines, crossed by transversal AE. So, angles FAE and CDE are congruent. These are acute angles in a right triangle, so the triangles AFD and DEC are similar by the AA postulate.

This similarity means that corresponding sides are proportional:

CE/CD = DF/DA

CE = CD(DF/DA) = 16(6/10) = h

h = 9.6

The second problem is identical to the first, but with different numbers.

CE = CD(DF/DA) = 14(8/10) = h

h = 11.2
