Answer:
810
Step-by-step explanation:
In this case the sample space would be the number of combinations that can be made with the numbers from 1 to 30 with the letters of the alphabet, from "a" to "z", for example:
A1, A22, C4, F9, etc
Now we know how many numbers are 30, now the alphabet has 27 letters, therefore, the number of combinations are:
27 * 30 = 810
Which means that the total number of results is 810.
9514 1404 393
Answer:
2
Step-by-step explanation:
The recommended way to multiply mixed numbers is to convert them to improper fractions. Where there are factors that cancel, this works nicely.
2,700 / 12 = 225
225 / 5 = 45
They can make 45 necklaces.

Answer:</h2>
The statement that best describes Imara's error is:
Option: D
D). She did not find the side lengths of the square with an area of 625.
<h2>
Step-by-step explanation:</h2>
Imara correctly did the previous calculation.
i.e. she correctly determined the area of square with side length 20 units (as 400 square units) and 15 units (i.e. 225 square units)
But when she sum the area of two squares then it won't give the length of hypotenuse it would give the area of a square.
Hence, the correct answer is:
Option: D
