Answer: The length of the third straw is 29 centimeters.
Step-by-step explanation: Given that Anja is creating a triangle using three straws and the lengths of two shorter straws are 20 cm and 21 cm.
We are to find the length of the third straw in centimeters so that Anja will create a right triangle.
The two shorter straws will make the legs of the right-angled triangle because they are shorter.
Since the third straw will be the largest, so it will make the HYPOTENUSE of the triangle.
In a right-angled triangle, we have
Hypotenuse² = length of one leg² + length of the other leg².
Therefore, we get

Thus, the length of the third straw is 29 centimeters.

Answer:
The equation that represents the table is:
Step-by-step explanation:
Taking two points from the table




As the slope-intercept form is

Plugging (2, 9) to find the y-intercept 'b'







so the equation becomes



Therefore, the equation that represents the table is:
The graph of the equation is also attached below.
(a) 48 %
(b) 74 %
Add the numbers associated with the name and then do 150 divided by that number, and then make the top number equal to 100. Whatever you did to make that top number 100 do the same thing to the bottom number.
