Answer:
6 by 3
Step-by-step explanation:
a rectangle as 2 equal sides. so if we know that it is 6 by 3, then 6+6+3+3
=12+6=18
the area of a rectangle is base * height. so 6 * 3 = 18
Well, all we have to do to figure out if Ms. Lee’s offer is reasonable is multiply the unit price ($18) by 7
18 x 7 = 126
Since she offered $146, she could actually purchase 8 pennants for $144
Therefore, her answer wouldn’t be reasonable
Hope this helps you

ABC ,⊿PQR,select an angle ∠ACB =θ
LET θ’s (opp,adj,hypo)=(AB,BC,AC) and (PQ,QR,PR)
Then by similarity,
sinθ=AB/AC=PQ/PR ,cosθ=BC/AC=QR/PR ,tanθ=AB/BC=PQ/QR
the corresponding ratio of (adjacent side/hypotenuse),and hence
the cosine ratio must be the same

Answer:
Step-by-step explanation:
cross multiply
-6 * 12 = 2 + z
-72 = z + 2
z = -2-72 = -74
Height of the woman = 5 ft
Rate at which the woman is walking = 7.5 ft/sec
Let us assume the length of the shadow = s
Le us assume the <span>distance of the woman's feet from the base of the streetlight = x
</span>Then
s/5 = (s + x)/12
12s = 5s + 5x
7s = 5x
s = (5/7)x
Now let us differentiate with respect to t
ds/dt = (5/7)(dx/dt)
We already know that dx/dt = 7/2 ft/sec
Then
ds/dt = (5/7) * (7/2)
= (5/2)
= 2.5 ft/sec
From the above deduction, it can be easily concluded that the rate at which the tip of her shadow is moving is 2.5 ft/sec.
