Answer
true
Step-by-step explanation:
Divide the total earnings for the workweek, including earnings during overtime hours,
The options are:
A) exactly one triangle;
B) no triangles;
<span>C) more than one triangle.</span>
First thing, let's see if these angles can make a triangle:
(81 + 52 + 47) = 180
We know that the sum of the inner angles of a triangle must equal 180°, therefore yes, they can be angles of a triangle.
With only the measure of the angles and nothing about the sides, we can construct as many triangles as we want: try, indeed, to construct a triangle with given angles bus sides of your choice; then, double the sides. You will get a triangle that is twice the size, but the angles remained the same.
Hence, the correct answer is C) more than one triangle.
Solve for x. I'll do it by completing the square:
2x² = 4x + 9
2x² - 4x = 9
x² - 2x = 9/2
x² - 2x + 1 = 11/2
(x - 1)² = 11/2
x - 1 = ± √(11/2)
x = 1 ± √(11/2)
x = 1 ± √22/2
x = (2 ± √22)/2
Take the solution with the positive square root. Then it follows that a = c = 2 and b = 22. So a + b + c = 26.
Answer: the second option is the correct answer.
Step-by-step explanation:
In an arithmetic sequence, the consecutive terms differ by a common difference.
The formula for determining the nth term of an arithmetic sequence is expressed as
Tn = a + d(n - 1)
Where
a represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = 6
d = 17
n = 18
We want to determine the value of the 18th term, T18. Therefore,
T18 = 6 + 17(18 - 1)
T18 = 6 + 17 × 17
T18 = 6 + 289
T18 = 295
Yes, Juan is correct only equal groups can be multiplied.
