Answer:
if that is supposed be a decimal then round tenths place which is still six
Step-by-step explanation:
The value of the angles should be. (x-40°). , (x-20°), (½x-10°) , not (x-40°) + (x-20°)+(½x-10°)
Sum of all the interior angles of a triangle is 180°.
So a equation can be made by the given data,
(x-40°) + (x-20°) + (½ x-10°) = 180°
x-40°+x-20°+½x-10° = 180°
2x+½x -60°-10° = 180°
5/2 x - 70° = 180°
5/2 x = 180° + 70°
5/2 x = 250°
x = 250° × 2/5
x = 50° × 2
x = 100°
So the angles are
x-40° = 100°-40° = 60°
x-20° = 100°–20° = 80°
½x-10° = ½(100)° - 10° = 50° -10° = 40°
The answer can be checked by putting the values of the angle we got in the second statement i.e. Sum of all the interior angles of a triangle is 180°.
60° + 80° + 40° = 100° + 80° = 180°
The number of books she would have completed in one day will be 2 books.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
Given that:-
Emily completed reading 24/3 books in 32/4 days
Emily completed 8 books in 4 days. The number of the books will be calculated by using the expression below:-
4 days = 8 books
1 day = 8 / 4 = 2 books
Therefore the number of books she would have completed in one day will be 2 books.

Answer:
10years
Step-by-step explanation:
100%+100%=double
100/10=10 years to reach 100% so after ten years you will have 200%/double
Answer:
- The point (x, y) → (-5, 0) is the vertex of the graph.
Step-by-step explanation:
As the given graph represents Parabola
- As we know that Parabolas always contain the lowest point, or the highest point if any given parabola is upside-down. This lowest or highest point is the location where the parabola tends to change its direction and called the 'vertex'.
Hence, from the given graph, we can easily determine that the parabola changes its direction at x = -5, and y = 0.
- Therefore, the point (x, y) → (-5, 0) is the vertex of the graph.
