Assuming he spends all the $24 on renting DVD's we can simply divide the money he has available with the price of each DVD in order to know how many he can buy.
$24/$4 = 6
Jack can rent a maximum of 6 DVD's
Answer:
approximate volume = = 28336 cubic ft.
Step-by-step explanation:
Base area = 70840 sq. ft
Each story is about 10 ft.
approximate height = 12*10 = 120 '
Volume of pyramid
= Base * height /3
= 70840 * 120 / 3
= 28336 cubic ft.
Answer:
<h2>SU = 3.5</h2>
Step-by-step explanation:
We have the triangle 30° - 60° - 90°.
Right triangles with 30-60-90 angles will have their ratio of the sides as
1 : √3 : 2 (look at the picture).
We have:
SR : SU : RU = 1 : √3 : 2
Therefore RU = 2SR and SU = SR√3.
We have RU = 4. Substitute:
2SR = 4 <em>divide both sides by 2</em>
SR = 2
SU = 2√3 ≈ 2(1.73) = 3.5
32 x 6 = 192. 32 x 4 = 128. Hope this helped.
Answer:
39,916,800ways
Step-by-step explanation:
This arrangement is permutation. Since it is a circular arrangement, the formula for calculating arrangement of objects sitting in a circular path is (n-1)! where n is the number of objects. Applying this formula in the question, the 12 students will sit in a circle in (12-1)! ways.
(12-1)! = 11!
= 11×10×9×8×7×6×5×4×3×2×1
= 39,916,800ways
