We want a in terms of b and c: <span>3a+4b=c
Isolate 3a on the left side: 3a = c - 4b
Divide all terms by 3:
a = c/3 - 4b/3 (answer)</span>
Answer: The correct answer is the third choice.
Step-by-step explanation: The question is asking you to look at pieces of data from the graph. The best way to do this question is to look at each question to determine whether the statement is true or false.
In looking at the each choice:
First one - The statement is true. Looking at the graph, a 40 and 50 year old person has the same average rate.
Second - The statement is true. Looking at the graph, you can see a steady decline from a 10 year old to a 20 year old person.
Third - The statement is false. A 10 year old and 20 year old do not have the same rate.
Fourth - The statement is true. A 20 and 30 year old have the same heart rate.
Answer: 26.13yards^2
Step-by-step explanation:
To find the area of the bottom part we can use the diameter.
6 yards. Divide it by half to have the Radius.
Now we use the formula to find the area of a circle which is
A = 3.14*R^2 Pie times radius squared.
A = 3.14*3^2
A = 3.14*9
A = 28.26 Now that we have the area of the circle divide it by 2.
14.13
Now to find the area of an isosceles triangle we use the formula
A = Base * Height Divided by 2.
A = 6*4/2
A = 24/2
A = 12
12 + 14.13 = 26.13
