Answer:
5.5 inches
Step-by-step explanation:
Because Length * Width = Area, Length * 12 = 66.
If we solve for Length by dividing both sides by 12, we end up with Length = 5.5 inches

Due today:
At a local car dealer, the ideal selling price of a car is $22,000. The dealer allows this price to vary $1200 .
Create an absolute value inequality that models the range of the price the dealer can sell the car. (Hint: Test your inequality to make sure the price is $1200 below and above the selling price works.)
We know that:
The ideal selling price is P = $22,000
The price can vary dP = $1,200
let's define p as the variable that represents the possible prices of the car.
We will find that the absolute value equation that represents this is:
|p - $22,000| ≤ $1,200
Now let's see how we get that, using the initial information we can get:
The minimum price can be:
mP = P - dP = $22,000 - $1,200 = $20,800
The maximum price can be:
MP = P + dP = $22,000 + $1,200 = $23,200
Then the range of allowed prices is:
mP ≤ p ≤ MP
$20,800 ≤ p ≤ $23,200
To write this as an absolute value equation, we use the general formula:
Ix - average| ≤ amount that it can vary
Replacing it with our values we get:
|p - P| ≤ dP
|p - $22,000| ≤ $1,200
Concluding, the absolute value equation that we wanted to find is:
|p - $22,000| ≤ $1,200

Answer:
f(-5) = 19
Step-by-step explanation:
f(t) = -3t+4
Let f(t) = 19
19 = -3t+4
Subtract 4 from each side
19 - 4 =-3t+4-4
15 = -3t
Divide each side by -3
15/-3 = -3t/-3
-5 = t
Answer:
the answer is -5
Step-by-step explanation:
F(t)=-3(t)+4
it told you that F(t) is equal to 19
so -3*-5=15+4=19

93,487,991 to the nearest hundred thousand
Answer:
93,500,000
Step-by-step explanation:
Rounding rule:
1) If the digit directly next to the one you are finding is 5 or greater, round up.
2) If the digit is 4 or less, round down.
Note the hundred thousands place value (underlined and bolded):
93,487,991
Look at the digit value directly next to the place value you are looking for. The value of the digit is 8. Because 8 is greater then 5, round up:
93,487,991 rounded to the nearest hundred thousand is 93,500,000.

Answer: See the diagram below
The table moves up and to the right
=========================================================
Explanation:
The lower right leg will move along that diagonal line shown on the right side.
Since the table is solid and not flexible, all of the other 3 points will move in the same pattern.
What results is what you see in the diagram below. The table moves to the right some distance and up some (other) distance along that diagonal path.
Note how the lower right leg is always on that path, since that path itself is the result of scraping that leg against the floor.
Also, I'm assuming your teacher wants purely a translation and nothing else. That means the table hasn't been rotated in any fashion.

The perimeters of the two rectangles at right are equal. Write and solve an equation to find the value of x and the common perimeter. (desperate need of help)
Answer:
write the expression for the perimeter of the 1st rectangle 6x
write the expression for the perimeter of the 2nd rectangle 4x + 30
write the equation 6x = 4x + 30
x= 15
perimeter = 90
Step-by-step explanation:
The perimeter is adding up all the sides of the rectangle.
So for the first one, we know two of the sides: x and 2x. The opposite sides have the same values. So the other two sides are x and 2x.
Therefore, the perimeter is
2x + x + 2x + x
or
6x
Similarly with the second rectangles:
(x+12) + (x+3) + (x+12) + (x+3)
Combine like terms
x + x + x + x + 12 + 3 + 12 + 3
4x + 30
Set these two equal to each other because the two perimeters are equal
6x = 4x + 30
Subtract 4x on both sides
2x = 30
Divide by 2 on both sides
x = 15
Check:
6(15) = 4(15) + 30
90 = 60 + 30
90 = 90
The common perimeter is
6*15 = 90 units
