If two similar figures have side lengths that differ by a factor of x, then their area will be different by a factor x².
The side length of Hunter's square of compost is 4 times larger than the 6 by 6 square. The area will be 4², or 16, times larger than the area of the 6 by 6 square.
Multiply 16 with 500 beetles.
Hunter can have 8000 beetles with his square of compost.
You can find the slope of this line directly from the graph. The "run" from -2 to 0 is 2, and the "rise" (actually, a drop) from 4 to 1 is -3. Thus, the slope is -3/2.
Eliminate the 2nd answer possibility; its slope is wrong.
The point-slope form of the eq'n of a str line is
y-k = m(x-h) Compare this to the first answer possibility:
<span>y + 5 = -3/2(x - 4). Recognize that k= -5 and h=4.
Check: does the point (4,-5) lie on the given line?
Yes. Thus, this is the correct formula.</span>
Answer:
x=21
<1=120
Step-by-step explanation:
So to find x set up an equation like this:
(5x+15)+(3x-3)=180
since the bottom and top lines are congruent they are 'interior angles on the same side of a transversal' which are always supplementary, so that's where 180 comes from.
calculate the equation and you'll get x=21 :D
next to find 1 just put 21 in place of x: 3(21)-3=60
since it's supplementary to angle 1 you take 180-60=120
angle <1=120!
2.5/5 simplified would be 0.5
