There exists a trigonometric identity which states that,
sin (A - B) = sin A cos B - cos A sin B
This is very similar to the given expression with A equal to 57° and B equal to 13°. The simplified form of the angle is,
sin (57° - 13°) = sin 44°
Answer:
Step-by-step explanation:
First you have to find the area of the rectangular grid. The area of a rectangle is length•width.
So:
A= 20•12
A= 240cm
Then you need to convert 240cm into mm.
240cm is 2400mm.
Then you need to figure out how many triangles can fit into the rectangle if all the triangles have an area of 25mm. So you divide 2400 by 25.
2400:25= 96
So Alex can fit 96 triangles into the grid.
Using the scatter plot, it is found that 4 visitors were there during the fourth hour.
<h3>What is a scatter plot?</h3>
- A scatter plot is similar to a function graph, as for each value of x, it will have the corresponding value of y.
Researching the problem in the internet, it is found that:
- The values of x represents each hour.
- The corresponding y-value represents the number of visitors during hour x.
- In the plot, we have that when x = 4, y = 4, hence, 4 visitors were there during the fourth hour.

Answer:
9.75 - the second one
Step-by-step explanation:
65 × 150 = 9750
to convert from ml to l you divide by 1000
9750 ÷ 1000 = 9.75
