Answer:
Step-by-step explanation:
Triangle ABC is a 45-45-90 right triangle. That means that segment BC also measures 10.
The big triangle as a whole is a 30-60-90. The side length across from the 30 degree angle is 10, so the whole length of BD is 10√3. However, since we already have the length of BC as 10, then segment CD measures
10√3 -10 which is 7.32
Flip the situation:
X + 3.25 = 4.72
Subtract 3.25 from both sides
X + 3.25 - 3.25 = 4.72 - 3.25
X = 1.47
Side length: 2 cm.
Volume of a cube:
V=a^3
(where V is volume, and a is side length)
If v=8, the formula would now be 8=a^3
Take the cube root of both sides
a=2.
3÷8+1÷8-(9÷8+5÷8)
=3÷8+1÷8-(14÷8)
=3÷8+1÷8-14÷8
=(3+1-14)÷8
=-10÷8
=-5÷4
=-1.25
C is the correct answer 3.785*2.5=9.4625 then multiply by 1000 and you get 9,462.5
