Answer:

10% of 45 is 4.5

30% of 45 is 13.5

Step-by-step explanation:

10% of 45 is 4.5 because you can multiply 4.5 10 times to get 45. Because 30% is 3 times the amount as 10%, you can multiply 4.5 x 3 to get 13.5

100 - [(25/5) x 10] = ?

Well, you can get rid of the brackets.
→100 - 50 = ?
Subtract!
→100 - 50 = 50

Which of the following is the line of symmetry for the figure shown below?
scoray [572]

Answer:

Line A

Step-by-step explanation:

A line of symmetry is a line that divides a shape into exactly two equal halves.

A triangle is a polygon with three sides and three angles. A scalene triangle has no lines of symmetry, an isosceles triangle has more than one line of symmetry while an equilateral triangle has three lines of symmetry.

From the diagram we can see that line A divides the figure into two equal halves, hence line A is the line of symmetry.
