Answer:

A closed circulatory system can have a single or double circulatory pattern. Fish have a single circulatory pattern, wherein the blood passes through the heart only once during each complete circuit. Oxygen-deprived blood from the body tissues comes to the heart, from where it is pumped to the gills.

Solve the compound inequality 6b &lt; 36 or 2b + 12 &gt; 6.
Ne4ueva [31]

The solution to the compound inequality given as 6b < 36 or 2b + 12 > 6 is b < 6 or b > -3

<h3>How to solve the compound inequality?</h3>

The compound inequality is given as:

6b < 36 or 2b + 12 > 6

Evaluate the like terms in the individual inequalities

6b < 36 or 2b > -6

Divide the individual inequalities by the coefficients of b

b < 6 or b > -3

Hence, the solution to the compound inequality given as 6b < 36 or 2b + 12 > 6 is b < 6 or b > -3

Dafna1 [17]

Answer:

39.9

Step-by-step explanation:

a/sinA = c/sinC

a/sin(77) = 16/sin(23)

a = sin(77) × 16/sin(23)

a = 39.89935764

Answer: 24 cm^2

explanation: the area of the triangle would be 6 because (3*4)/2=6. the area of the larger rectangle would be 12 because 4*3=12. the missing side is found by subtracting 8 by 4. the smaller rectangle’s area would be 6 because 4*1.5=6. add 6, 12, and 6 together and you get 24. i hope this helps!!
