It is true that (-4)^2 = 16; however, it doesn't make sense to have a square with a negative side lengths. Lengths and distances must be positive numbers.
So in many problems, we'll just ignore the negative solution to equations like x^2 = 16. It makes sense to only consider x = 4 for situations like this.
8.0 is greater than 0.8 because 8.0 is a unit but 0.8 is lesser than uint
These questions are all of the same type: division. They ask to find how many of a number can fit in another number.
As for question 5, there are 42 pounds of dog food, and pound of dog food is used for each feeding. To find the number of times Mr. Lash can feed his animals, divide 42 by . The answer is 48.
Solving the rest of the questions by this method, here are the answers. If you wish you can do them yourself to verify your understanding.
6) 12
7) 4
8) 8
9) 2
Note: in question 9, the question is in reverse order compared to the other questions.
Answer:
The 50th term is 288.
Step-by-step explanation:
A sequence that each term is related with the prior by a sum of a constant ratio is called a arithmetic progression, the sequence in this problem is one of those. In order to calculate the nth term of a setence like that we need to use the following formula:
an = a1 + (n-1)*r
Where an is the nth term, a1 is the first term, n is the position of the term in the sequence and r is the ratio between the numbers. In this case:
a50 = -6 + (50 - 1)*6
a50 = -6 + 49*6
a50 = -6 + 294
a50 = 288
The 50th term is 288.
Your answer would be 1+1=2
This took me a while to figure out
