Answer:
By delivering oxygen to the cells
Step-by-step explanation:
This is the answer because:
The respiratory system is responsible for moving gases into and out of the blood because it gives the bloodstream the oxygen needs. The circulatory system is responsible for moving blood to all parts of the body and transport nutrients. The circulatory system works with the respiratory system to exchange carbon dioxide and oxygen.
Answer:
25.8 degrees
Step-by-step explanation:
Multiply 4.3 by 6
Answer: 8π square meters
Explanation:
First, we convert the angle of the sector to radians, which is 30 degrees.
Note that 180 degrees is equal to π radians. Since 30 degrees is equal to 180 degrees divided by 6,
30 degrees = π/6 radians
Thus, the angle of the sector in radians is π/6.
So, the area of the sector is given by
(Area of sector) = (1/2)(radius)²(angle of the sector in radians)
= (1/2)(radius)²(π/6)
= (π/12)(radius)²
= (1/12)(π)(radius)²
Note that
(Area of the circle) = (π)(radius)² = 96π
Therefore, the area of the 30-degree sector is given by
(Area of the sector) = (1/12)(π)(radius)²
= (1/12)(Area of the circle)
= (1/12)(96π)
(Area of the sector) = 8π square meters
Answer:
Below.
Step-by-step explanation:
The number of combinations of 7 from 32 = 32! / 7! (32-7)!
= 3365856
So it is 1/ 3365856 = 0.000000297
or about 3 in 10,000,000.
