3, 5, and 6 are incorrect.
In number 3, you have all the steps correct, except for the last one. Instead of adding 19 to 25, you would multiply it, because there is no addition sign in between the absolute value sign and 5^2. Thus making the answer 475.
In number 5, you first square -2. -2 * -2 ( or -2^2) = 4. Next, you square 3. 3 * 3 (3^2) is 9. Then, you subtract 9 from 4 to get -5. The absolute value of -5 is 5, making 5 the answer. Absolute value is kind of like the distance from zero, for instance -5 is 5 units away from 0 and the absolute value can never be a negative number. Thus making 5 the answer.
In number 6, you first solve the parenthesis. 2 - 3 = -1 and -1 * -1 (-1^2) is 1. Next, you square -3. -3 * -3 (-3^2) = 9. Then, you subtract 1 from 9 to get 8. The absolute value of 8, is 8. Finally, multiply -4 and 8 to get -32. Thus meaning -32 is the answer.
I hope this helps!
Answer:
63 pounds
Step-by-step explanation:
Given data
Quantity of meat= 18 pounds
TIme taken= 2 hours
Rate= Quantity/Time taken
Rate= 18/2
Rate= 9 pounds per hour
Now time= 7 hours
Rate= 9 pounds per hour
Quantity= Rate*Time
Quantity= 9*7
Quantity= 63 pounds
Answer:
The exact distance is 
miles.
The distance is approximately 10.4 miles.
Step-by-step explanation:
It is given that a rectangular city is 3 miles long and 10 miles wide. So,
Length = 3 miles
Width = 10 miles
We need to find the distance between opposite corners of the city. It means, we need to find the length of the diagonal of the rectangle.
Using Pythagoras theorem, the length of diagonal is
where, l is length and w is width.
Substitute l=3 and w=10.
The exact distance is miles.
Now,
The distance is approximately 10.4 miles.
The median would be the same number but multiplied by whatever number you multiplied all the numbers by
