Answer:The following data are inconsistent because the number of students that offer the three subject gives us a negative value. X= -4. Which shouldn't be. Therefore the data are inconsistent.
Step-by-step explanation:
See attached picture for explanations.
Answer:
The anwser is A the first one 8y+12x= 150 and x+y+ 12
Step-by-step explanation:
First you need the prices to equal how much money she had, im guessing she had 150 because all the anwsers say she did by looking at them. So, that gives you 8y and 12x is less or equal to 150. Then oboulsly the cominded number of books x and why must be at least (greater or equal to) 12 giving x+y is greater or equal to 12
Answer:
8 hours
Step-by-step explanation:
Using the relationship
speed = = = 42
travelling at a rate of 42 mph , then
time = = = 8 hours
The above answer can be calculated as -
We can use Pythagoras Theorem to prove that a triangle is a right-angle triangle if the square of the two shorter legs add up to be the square of the longest leg.
In this case, we need to prove that
4² + 10² = 12²<u>Pythagoras Theorem:</u>
Therefore a triangle with side lengths 4 ft, 10ft and 12 ft is not a right angle triangle.
