Answer:
<h3>
D. 5 x 10⁶ ÷ 6.6 x 10⁴</h3>
Step-by-step explanation:
If 6.6 x 10^4 square miles of florida costs $5 X 10^6, then to get one square miles we will follow the given steps below;
6.6 x 10^4 mi² = $5 X 10^6
1mi² = $x
Cross multiply;
$5 X 10^6 * 1 = 6.6 x 10^4 * x
6.6 x 10⁴ x = 5 X 10⁶
Divide both sides by 6.6 x 10⁴ to get x;
6.6 x 10⁴ x /6.6 x 10⁴ = 5 x 10⁶/6.6 x 10⁴
x = 5 x 10⁶ ÷ 6.6 x 10⁴
x = 0.76*10⁶⁻⁴
<em>x = $0.76*10²</em>
<em />
Hence the key strokes on a calculator will give the cost the United States paid for each square mile of Florida is 5 x 10⁶ ÷ 6.6 x 10⁴
Answer:
64 degrees
Step-by-step explanation:
Since the triangles are similar they have the same angle measures
![\frac{21}{14}= \frac{6}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B21%7D%7B14%7D%3D%20%5Cfrac%7B6%7D%7B4%7D)
∠P = ∠S ∠R =∠U ∠Q=∠T
We know 2 of the angle measures: ∠S and ∠R, and since they are similar we know ∠P and ∠U
In triangles the sum of all angle measures is always 180 degrees, so we can solve for ∠Q with this formula
![A+B+C=180](https://tex.z-dn.net/?f=A%2BB%2BC%3D180)
![46+70+C+180](https://tex.z-dn.net/?f=46%2B70%2BC%2B180)
![116+C=180](https://tex.z-dn.net/?f=116%2BC%3D180)
subtract 116 from both sides
![C=64](https://tex.z-dn.net/?f=C%3D64)
Therefore ∠Q is equal to 64 degrees
the value is n=1/4

D. 40
follow the pattern
1 band director calls 3 members. = 4
Each member calls 3 more members 3(3) = 9
Then each of those 9 call 3 more members 9(3) = 27
Add them up
4+9+27 = 40
3.6 = 3 3/5
(sorry if it's wrong)
