Answer:
A. 270.9
Step-by-step explanation:
We know that the rule of significant figures for addition and subtraction states that 'the number of places after the decimal point in the result is equal to the least number of decimal places in each term.'
So, 67.31 - 8.6 + 212.198 = 67.31 + 212.198 - 8.6 = 279.508 - 8.6 = 270.908
Now, the resultant number is 270.908
Using the rule of significant figures, we get that, the number of places after the decimal point in 270.908 will be equal to the least number of decimal places i.e. 1 ( in 8.6 )
Hence, 67.31 - 8.6 + 212.198 = 270.9
Answer:
The measure of the largest angle is 72º.
Step-by-step explanation:
We will first solve for x. We know that the sum of the interior angles of a triangle is 180º, so 15x + 21x + 24x is equal to 180º. This means that 60x = 180º, so x = 3º. The largest angle is 24x, which is 72º.
For us to get the solutions of the given function, we let f(x) be equal to zero and solve for the values of x.
f(x) = 12x² - 13x + 3 = 0
To get the two values of roots, a and b, we use the concepts presented below.
a + b = -B/A
ab = C/A
Substituting the known values,
a + b = -(-13/12) = 13/12
ab = 3/12
The values of a and b from the equation are 3/4 and 1/3, respectively.
The solution set then becomes {3/4, 1/3}.
