Answer:
Step-by-step explanation:
let side of cube=x
volume of cube=x³
x³=10.645

or x≈2.2
a.
length of side of cube=2.2 cm
b.
length of wire used=3[4×2.2]=26.4 cm
Answer:
Step-by-step explanation:
This is a right triangle trig problem. The height of the tree is the height of the triangle, and the length of the wire is the hypotenuse of the triangle. Using Pythagorean's Theorem, we can find the length of the base, which is how far he must secure the bottom of the wire from the base of the tree.
and
and
so
x = 3 m
10 squared = 100
10*10=100
We don't know what the variable 'w' stands for, so we can't find the product. But we can write the sentence as an equation:
737w
The answer is B because the line is not dotted.
