Answer:
B
Step-by-step explanation:
using the tangent ratio on the triangle on the right and the exact value
tan60° = 
, then letting the altitude be h
tan60° = 
= 
= ( multiply both sides by h )
11
= h × ( divide both sides by )
11
= h
using the sine ratio in the triangle on the left and the exact value
sin45° = 
, then
sin45° = 
= 
= 
= ( cross- multiply )
× x = 22 ( divide both sides by )
x = 22
The expression would be > 0.
Subtracting a negative is the same as adding a positive; therefore -18--18 = -18+18 = 0. Since we know that x>-18, 0 is below anything we could get from this.
Found a great explanation + 1105p = £11.05
When x=1, 7x+3 = 10.
When x=2, 7x+3 = 17.
When the value of 'x' changes from '1' to '2', the value of 7x+3 changes
from '10' to '17' . . . a distance of '7' .
That's what the ' 7x ' in the equation means, and that's what we mean
when we say that the 'slope' of the equation is '7'. 'y' changes '7' for
every '1' that 'x' changes.
<u>Answer</u>
∛729
<u>Explanation</u>
The volume of an object is the amount of space that the object can occupy.
The general formula for getting the volume of a regular object is:
Volume = Base area × Height
For a cube, all sides are equal.
∴ Volume of a cube = length × length × length
= (length)³
This means given the volume of a cube we can get the length of one side as shown.
Volume = (length)³
length = ∛volume.
∴ Volume = 729 in³
Length = ∛729 inches. This will give you the number of cubes 1 inches can fit along one side.
