Answer:
153.36g
Step-by-step explanation:
Density is defined as the ratio of mass per unit volume of a material.
Density = Mass/Volume
Given the edge of a cube which is equivalent to its length L to be 6cm.
Density of the cube = 0.71g/cm³
Volume of the cube = L³
Volume = 6³
Volume of the cube = 216cm³
Mass = Density × Volume
Mass of the cube = 0.71×216
Mass of the cube = 153.36grams
Answer:
Step-by-step explanation:
Let x = the width of the garden
Then x + 3 = the length of the garden
Area of garden = length × width
A = lw = x(x+ 3)
width = x = 20 ft
length = x + 3 = 20 +3 = 23 ft
Check:
OK.
Answer:
c
Step-by-step explanation:
(2x²)³ = 2³(x^(2×3))
=2³x⁶
=8x⁶

Taking the side we can't quite see, I would guess it is an 8.
A 45 45 90 triangle is isosceles.
The two legs are equal.
x = 8

Little harder
The tangent of the angle is Tan(x) = opposite over adjacent
opposite = 10
adjacent = 15
Tan(x) = 10/15
Tan(x) = 2/3
x = tan-1(2/3)
x = tan-1(0.6666666667)
x = 33.7 degrees.
Do you know how to put this in your calculator.
