Step-by-step explanation:
=multiple ways to climb a tower
When n = 1,
tower= 1 cm
= 1
When n = 2,
tower =2 cm
= 2
When n = 3,
tower = 3 cm
it can be build if we use three 1 cm blocks
= 3
When n = 4,
tower= 4 cm
it can be build if we use four 1 cm blocks
= 6
When n > 5
tower height > 4 cm
so we can use 1 cm, 2 cm and 4 cm blocks
so in that case if our last move is 1 cm block then
will be
n —1 cm
if our last move is 2 cm block then
will be
n —2 cm
if our last move is 4 cm block then
will be
n —4 cm

48/4= 12 pens per box
12*9 = 108 pens in 9 boxes
The slope m of a line
through points

and

is given by :<span>

Thus, the slope of the line passing through points </span><span>(−1, 7) and (2, 10) is
</span>

<span>
The equation of a line with slope m passing through a point P(a, b) is given by
(y-b)=m(x-a).
We can consider any of the points (-1, 7), or (2, 10). Let's choose (2, 10):
y-10=1(x-2)
y-10=x-2
y-x=-2+10
y-x=8
Answer: </span><span>C. −x+y=8</span>
C. h=V/B to solve for this you need to get the variable h by itself and since h is being multiplied to B you use the opposite operation of division by divide both sides by B. Then you have h solved for h=V/B
<em>$ 232.90</em>
- Step-by-step explanation:
<em>62% ........... $144.40</em>
<em>100% ..........$ x</em>
<em>x = 144.40×100/62</em>
<em>= 14440/62</em>
<em>= $ 232.90</em>
