Answer:
10.125 feet.
Step-by-step explanation:
you can use the rule of three to answer this question, the data we have is:
inches feet
1 → 4 1/2
2 1/4 → x
tha last table just indicates what the problem tells us, that one inch is equal to 4 1/2 feet and we want to know how much in feet the 2 1/4 inches are.
For this we multiply the cross quantities:
the actual length of the kitchen is 10.125 feet.
hmmm first off let's convert the √3 +i to trigonometric form, and then use De Moivre's root theorem, bearing in mind that √3 and i or 1i are both positive, meaning we're on the I Quadrant.
Answer: 1) 5040 and 2) 165
Step-by-step explanation:
1) Here total number of letters = 10
The number of permutations that can be formed using 4 letters at a time
= P (10, 4)
=
=
=
=
= 10 × 9 × 8 × 7
= 5040
2) Here the total number of machine = 11
The different combinations of machines can Geoff choose from to use
=
=
=
=
= 11 × 5 × 3
= 165
