The question is missing some important details required to answer the question. I found a similar question, so I will answer using this details. If there is any differences in the details, you can still use my working by changing the value given:
Abdul will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $38 and costs an idditional $0.11 per mile driven. The second plan has an initial fee of $49 and costs an additional $0.07 per mile driven.
How many miles would Abdul need to drive for the two plans to cost the same?
Answer:
275 miles
Step-by-step explanation:
Let the distance travel be X
First plan:
Initial fee: 38
Per mile: 0.11
So the total cost is
C1 = 38 + 0.11X
Second plan:
Initial fee: 49
Per mile:0.07
So the total cost is
C2 = 49 + 0.07X
Since the question asked about when the total cost be the same, we can say that C1 = C2
C1 = C2
38 + 0.11X = 49 + 0.07X
0.11X - 0.07X = 49 - 38
0.04X = 11
X = 11/0.04 = 275
At 275 miles, the cost will be the same.
Answer:
30240 number of ways are there to seat them
Step-by-step explanation:
Total number of ways of arranging 9 people on 9 chairs in circular manners = (9-1)! = 8! =
number of ways A sit always sit next to B = AB together makes a single and
therefore total number of arrangements for this = 7+(AB) = 8 that is 8 persons sitting in circular manner
number of ways = (8-1)! =7! = 5040
likewise number of arrangements for A and C will be = 5040
Total number of ways such that A cannot sit next to B or C = total ways of 9 persons - total number of A always sitting next to B - total number of ways always sitting next to C = 8! - 7!-7!
= 40320- 5040-5040
= 30240

The volume of the bedroom is 11 x 10 x 10 = 1100 cubic feet.
The volume of the den is double, so 1100 x 2 = 2200 cubic feet.
Divide the volume of the den by the height, since it is the same as the bedroom, this will give you the area:
2200 / 10 = 220 square feet.
Two sets of numbers that could equal 220 are 22 x 10 or 22 x 11
The room can be 20 ft by 10 ft or 22 ft by 11 ft and the volume is 2200 cubic feet.
Answer:
Step-by-step explanation:
observe
||a–b+c|| = ||a+b+c||
(a-b+c)² = (a+b+c)²
(a+b+c)² – (a-b+c)² = 0
((a+b+c)+(a-b+c))((a+b+c)–(a-b+c)) = 0
(2a+2c)(2b) = 0
(a+c)b = 0
a•b + c•b = 0
||a||×||b||×cos(π/8) + ||c||×||b||×cos(θ) = 0
