in one hour varies no more than 45 calories. Which inequality below represents this scenario?
A. |c - 450| ≤ 45
B. |c + 450| ≥ 45
C. |c - 45| ≤ 450
D. |c - 45| ≥ 450

We are given the data that the threshold that lucy burns is 450 calories. However, there are fluctuating counts that tell that no more than 45 calories are burnt than 450. Hence, the inequality is A. |c - 450| ≤ 45 . Hence the absolute value considers both lower and higher than 450.

The <em><u>correct answer</u></em> is:

A. |c - 450| ≤ 45  

Explanation:

Lucy's goal is 450 and the number of calories she actually burns is c.  The difference between her goal and the number she actually burns is no more than 45; this is where the expression c-450 comes from, as well as the less than or equal to 45.  However, we are not told that she always burns more or always burns less than her goal; therefore we must consider both, and this leads to our absolute value inequality.

faltersainse [42]

Answer:

Step-by-step explanation:

a= adult ticket

a= student ticket

5a+1s=2874

1a+1s=1246

Subtract the second equation from the first one

4a=1628

a=407

a+s=1246

407+s=1246

* The nth term of sequence A is 3n − 2 The nth term of sequence B is 10 − 2n Sally says there is only one number that is in both
Nina [5.8K]

Answer:

Sally is not right

Step-by-step explanation:

Given the two sequences which have their respective n^{th} terms as following:

Sequence A. 3n - 2

Sequence B. 10 - 2n

As per Sally, there exists only one number which is in both the sequences.

To find:

Whether Sally is correct or not.

Solution:

For Sally to be correct, we need to put the n^{th} terms of the respective sequences as equal and let us verify that.

3n-2=10-2n\\\Rightarrow 3n+2n=10+2\\\Rightarrow 5n=12\\\Rightarrow n = \dfrac{12}{5}

When we talk about n^{th} terms, n here is a whole number not a fractional number.

But as per the statement as stated by Sally n is a fractional number, only then the two sequences can have a number which is in the both sequences.

Therefore, no number can be in both the sequences A and B.

Hence, Sally is not right.
