Answer: Option D.
Step-by-step explanation:
A figure has a line of symmetry if we can draw a line through the figure, in such way that the line cuts the figure in exactly two equal halves.
Then any figure that can be cutin exactly two halves, is a correct answer to this question.
Then:
For a circle, the line of symmetry is the diameter of the circle.
For the square, the line of symmetry can be obtained by cutting the square with a line that is perpendicular to one of the sides, and cuts that side exactly on the midpoint.
For an equilateral triangle, the line of symmetry is the line that cuts any base in the midpoint and also passes through the opposite vertex.
Then all the figures are correct options, then the correct option is D
Answer:
1,260 books (or C)
Step-by-step explanation:
1. 2/5 of fiction (12,500) are out, so 5,000 are out
2. 2/5 of non-fiction (19,000) are out, so 7,600 are out
3. Total books checked out are 12,600
4. 1/10 of checked out books are due this week, so 1,260 books (10%)
Answer:
1029 minutes or 17.15 hours
Step-by-step explanation:
25+0.06M=86.74
0.06M=61.74
M=61.74/0.06=1029
Answer:
m = 3.53972077085
Step-by-step explanation:
-3 × 
- 3 = -27
Subtracting -3 from both sides of the equation gives;
-3 × = -24
Dividing by -3 on both sides of the equation gives;
= 8
Let 2m - 5 = x
xloge = 3log2
x = 
= 2.0794415417
So,
2m - 5 = 2.0794415417
2m = 2.0794415417 + 5
2m = 7.0794415417
Dividing by 2 on both sides of the equation gives:
m = 3.53972077085
52.22 - 39.58 = 12.64
12.64 / 4 = $ 3.16 per shirt
