Answer:
Integer that represents Melissa's location with respect to sea level: 
Integer that represents Brian's location with respect to sea level: 
Step-by-step explanation:
By definition, Integers can be negative, positive or zero.
Let be zero (
) the sea level.
According to the information provided in the exercise, you know that Melissa's location is at 27 meters above the sea level.
Therefore, you can conclude that the integer that represents her location with respect to sea level, is greater than zero (this means that it is positive).
Then, this is:
Brian's location is 21 meters below sea level.
This indicates that the integer that represents her location with respect to sea level is less than zero (it is negative).
Therefore, this is:
Answer:
-2 9/10, -1.8, -5/3, -0.9, 2/10, 11/10, 2.3, 10/4
Step-by-step explanation:
Step-by-step explanation:
X^2 +4X +4=12 subtract the 12 from both sides
X^2 +4x-8= 0
now factor if possible since this equation is not factorable you can use the quadratic formula
Answer:
you spent all together 40.2+24.5+37.8=$102.50.
you saved 19.8+10.5+7.2=$37.50
Step-by-step explanation:
To find the amount we spend, we multiply the original price by the decimal conversion of each fraction. Then we add the amounts together.
Sneakers cost $60 and you bought them at 2/3=0.6666....
60(0.67)=$40.20 and saved $19.80
Sweater costs $35 and you bought it at 7/10=0.7
35(0.7)=$24.50 and saved $10.50
A jacket costs $45 and you bought it at 5/6=0.8333...
45(0.84)=$37.80 and saved $7.20
We spent all together 40.2+24.5+37.8=$102.50.
We saved 19.8+10.5+7.2=$37.50
We could of spent paying regular price 60+35+45=$140. To find the fraction we place the total we actually paid over the total regular price.
Answer: $169,500
Step-by-step explanation:
The mean simply means the average price of a set of a numbers that are given. For one t calculate the mean, one has to add the numbers that are given and then divide them by the amount of numbers.
I'm the case above, the numbers given are $165,000, $188,000, $175,000, and $150,000.
Mean = ($165,000 ,+ $188,000 +$175,000 + $150,000) ÷ 4
= $678,000/4
= $169,500
