Answer:

the correct answer is C. 45

Step-by-step explanation:

so 1/5 means there are 5 peice to make a whole...

so if you cut an apple into 5 parts, each slice of that apple is 1/5

so if you cut 9 apples into 5 slices its just multiplication...

5*9=45

**for my visual learners** in the parenthesis are groups of 5 sticks

( ///// ) **those are your apple slices** **now just do that exactly 9 times**

( ///// ) ( ///// ) ( ///// ) ( ///// ) ( ///// ) ( ///// ) ( ///// ) ( ///// ) ( ///// )

   5       10      15       20      25       30      35      40      45

i really hope this helps <3

If you know trig please help! Will give brainliest!

Answer:

sin^2α

Step-by-step explanation:

I will just  pose  x instead  of alpha  here to make things simpler

\tan ^2\left(x\right)\left(2\cos ^2\left(x\right)+\sin ^2\left(x\right)-1\right)\\\\

we know that sin^2x = 1 -  cos^2x so...

=\left(-1+1-\cos ^2\left(x\right)+2\cos ^2\left(x\right)\right)\tan ^2\left(x\right)

=\cos ^2\left(x\right)\tan ^2\left(x\right)

we can rewrite using trigonometric identities (tan = sin/cos)...

=\left(\frac{\sin \left(x\right)}{\cos \left(x\right)}\right)^2\cos ^2\left(x\right)\\= \sin ^2\left(x\right)

The dimensions of a rectangular prism are shown below: Length: 1 and 1 over 3 feet Width: 1 foot Height: 2 and 1 over 3feet The

Answer:

  • 84 small cubes
  • 3 1/9 unit cubes

Step-by-step explanation:

A cube that is 1/3 ft on a side will fit 3 in a foot. In terms of the 1/3 ft small cube, the dimensions of the prism are ...

  1 1/3 ft = 4 small cubes

  1 ft = 3 small cubes

  2 1/3 ft = 7 small cubes

Then the volume in terms of small cubes is ...

  V = LWH = (4)(3)(7) = 84 small cubes

__

There are 3×3×3 = 27 small cubes in a 1-ft unit cube, so the prism volume in terms of unit cubes is ...

  84/27 = 3 1/9 . . . unit cubes

__

<em>Additional comment</em>

The largest dimension of the prism is just over 2 ft, so the maximum number of unit (1 ft) cubes that will fit is 2. To fill the volume with 3 1/9 unit cubes, those would have to be cut and fit into the space.
