Answer:
7. 2355 m
8. 1570 km
9. 157 cm
10. 40.82 m
Step-by-step explanation:
The circumference of a circle is pi * diameter or 2 * pi * radius.
If you are given the diameter, just multiply it by pi, 3.14.
If you are given the radius, then multiply the radius by 2 and then by pi, 3.14.
7. d = 750 m
circumference = pi * d = 3.14 * 750 m = 2355 m
8. d = 500 km
circumference = pi * d = 3.14 * 500 km = 1570 km
9. r = 25 cm
circumference = 2(pi)r = 2 * 3.14 * 25 cm = 157 cm
10. r = 6.5 m
circumference = 2(pi)r = 2 * 3.14 * 6.5 m = 40.82 m
 
        
             
        
        
        
8 shakers will fit  becuase 4 shakers equal 5 ounces and you multiply it by two and you get 10
        
                    
             
        
        
        
<h3>5:16</h3>
The ratio is supposed to be pennies to total amount of coins. The total amount of coins--including pennies--is 16. This can be proven by this equation:
5 + 6 + 5 = 16
Now you put the ratio together by taking the amount of pennies (5) and total amount of coins (16). Your ratio should look like this:
5:16

The observatory telescope has 22 times the magnifying power compared to the small telescope.
Data;
- small telescope = 150 times
 - large telescope = 3300
 
<h3>Division of Numbers</h3>
To solve this question, we have to divide the large telescope by the small telescope to calculate it's magnifying power.
 
The magnification of the observatory telescope is 22 times greater or larger than the small telescope.

Answer:
The sweat chloride reference value is less than 30 mmol/L. A value of more than 60 mmol/L of chloride in the sweat is consistent with a diagnosis of cystic fibrosis. The values of 30-60 mEq/L may represent heterozygous carriers, these carriers cannot be accurately identified with a sweat chloride test.
