The answer is A because all the other answers don’t use the cooperative denominators
Answer:
$30
Step-by-step explanation:
Just multiply
Step 1
<u>Find the total area</u>
Total area=(1,150,000/18,075)=63.62 square kilometer
The area of a circle is equal to
![A=\pi * r^{2} \\ 63.62= \pi * r^{2}\\r=\sqrt{(63.62/\pi)} \\r=4.5\ km](https://tex.z-dn.net/?f=%20A%3D%5Cpi%20%2A%20r%5E%7B2%7D%20%5C%5C%2063.62%3D%20%5Cpi%20%2A%20r%5E%7B2%7D%5C%5Cr%3D%5Csqrt%7B%2863.62%2F%5Cpi%29%7D%20%5C%5Cr%3D4.5%5C%20km%20)
therefore
the answer is
![4.5\ km](https://tex.z-dn.net/?f=%204.5%5C%20km%20)
Answer:
1 + 72 ÷4 × 2 =10 with brackets it equals 10
1 + (72 ÷ (4 × 2)) =10
Step-by-step explanation:
Answer:
∠3 = 60°
Step-by-step explanation:
Since g and h are parallel lines then
∠1 and ∠2 are same side interior angles and are supplementary, hence
4x + 36 +3x - 3 = 180
7x + 33 = 180 ( subtract 33 from both sides )
7x = 147 ( divide both sides by 7 )
x = 21
Thus ∠2 = (3 × 21) - 3 = 63 - 3 = 60°
∠ 2 and ∠3 are alternate angles and congruent, hence
∠3 = 60°
