Find the value of x and the length of each chord.

Tiffany has a spinner that is split into four equal sections: red, blue, green, and yellow. Tiffany spun the spinner 680 times.

Lyrx [107]

Probability of getting Green is 1/4
1/4 ×680 = 170
so choose nearest answer will 187

Think About a Plan Write an indirect proof.

Alekssandra [29.7K]

1) Either $\ell \parallel p$ or $\ell$ ∦ $p$ (only two possibilities)

2) Assume $\ell \parallel p$ (one of two possibilities)

3) $\angle 1 \cong \angle 2$ (if two parallel lines are cut by a transversal, the corresponding angles are congruent)

4) But $\angle 1$ is not congruent to $\angle 2$ (given)

5) So $\ell$ ∦ $p$ (only other possibility)

If a semi truck's trailer is 40 feet long, 10 feet wide, and has a height of 8 feet, what is its volume?

Temka [501]

First multiply 40 and 10 to get 400. Then multiply 400 by 8 to get 3,200.

Your answer would be: 3,200
