Since 6 species are not threatened, 22 - 6 = 16 species are threatened.
% threatened = 16/22 x 100 = 73%
Answer:
There is 1/4 of a quart of papaya juice
Step-by-step explanation:
To figure this out I divided 8 and 8 to get one cup of carrot juice. Then I divided 2 and 8 to figure how much papaya juice was there for one cup of carrot juice. Then after I divided for the papaya I got 0.25 or 1/4 of a quart of papaya.
<span>Nate’s method works because multiplication and division are the inverse of each other. This means that when you divide 15 (the dividend) by 5 (the divisor) and get 3 (the quotient), the quotient and the divisor multiplied together are factors of the dividend, which becomes a product.</span>
The length of arc AB is 3π given that radius of the circle is 27 units and the angle made by the arc AB at the center of the circle is 20°. This can be obtained using the formula to find arc length.
<h3>Find the length of the arc AB:</h3>
<u>Formula used for finding </u><u>arc length</u><u>:</u>
- If the angle made by the arc at the center of the circle is in degrees, the formula to find the length of the arc is,
⇒ L = 2 π r (θ/360°)
where r is the radius of the circle and θ is the angle made by the arc at the center of the circle.
- If the angle made by the arc at the center of the circle is in radians, the formula to find the length of the arc is,
⇒ L = r × θ
where r is the radius of the circle and θ is the angle made by the arc at the center of the circle.
Here in the question it is given that,
r = 27 units
θ = 20°
Since the angle made by the arc at the center of the circle is in degrees, the formula to find the length of the arc is,
⇒ L = 2 π r (θ/360°)
L = 2 π (27) (20°/360°)
L = π (27) (20°/180°)
⇒ L = 3 π
Hence the length of arc AB is 3 π given that radius of the circle is 27 units and the angle made by the arc AB at the center of the circle is 20°.
