Well,first you have to calculate the loss on both stocks.Then you need to sum them up and find his totall loss.Finally, you have to tutn it to prescentace. Your result is about 16.2%(I figured it might not be distinguishable in the picture I sent you.)
Your answer is correct in the sense that 14 ≤ x ≤22 since the temperature is 18 ° plus/minus 4°. However, the wording of the problem implies that it wants your final answer in terms of absolute value.
Based on your work, you understand the basics of the problem, and you correctly expressed it as an inequality. The problem is how to express it with an absolute value and only one inequality sign.
The word "within" implies that ≤ is the correct symbol, rather than < (you were correct to use that symbol)
We can word the expression in this way: The difference between the real temperature and 18° is less than or equal to 4. Difference in this sense is a positive number whether the real temperature is lower or higher than 18, so absolute value is implied.
We can express it mathematically this way:
|18-x| ≤ 4
Plug a few numbers in for X to make sure it makes sense.
If X equals 16 (within the range), |18-16| = 2, which is less than 4
If X equals 20, |-2| equals 2, which is less than 4
If X equals 10, |18-10| = 8, does not comply with our inequality.
Answer:
1. The value of will become
2. The value of will become and the value of from
Step-by-step explanation:
Given ,
- <em>The price of each baseball is $m dollars</em>
- <em>The amount he already spent on other things is $b dollars</em>
- <em>Let's the the total amount spent by Robert be $c. </em>Thus ,
According to the question , the given amount for spending totally is a constant = $c .
Thus ,
1<em><u>. If the expenditure on other equipment doubles , and payment remains constant ,</u></em>
This is the expression of price of baseball.
2.<em><u> If the cost of baseball , m dollars is tripled, then value of b :</u></em>
This is the new value of the price of other equipments
Answer:
10^2
Step-by-step explanation:
small number next to the 10 is how many spaces to the right. its called the exponent
10^2 means 2 spaces to the right
with 10^2 2.33 becomes 233
First you reduce the fraction
3 6/20 = 3 3/10
Now you do the fractional division 3/10 = 3 ÷ 10 = .3
3.3
