Answer:
The perimeter of a rectangular rug is 40 feet
Perimeter=2×(length+ width)
Let the width of the rug be x
According to the above problem,
40=2(12+x)
40/2=(12+x)
20=(12+x)
x=(20-12)
x=8
Hence, the width of the rug is 8 feet.
The width of the rectangular rug is 8 feet.
What is Perimeter?Perimeter of a straight sided figures or objects is the total length of it's boundary.
Given the perimeter of a rectangular rug and it's length.
Perimeter of rectangular rug = 40 feet
Length of the rectangular rug = 12 feet
We have to find the width of the rectangular rug.
Perimeter of a rectangular shape = 2 (l + w), where l is the length of the rectangle and w is the width of the rectangle.
Substituting these values,
Perimeter = 2 (l + w)
40 = 2 (12 + w)
40 / 2 = 12 + w
20 = 12 + w
w = 20 - 12
w = 8 feet
Hence the width of the rectangular rug is 8 feet.

I have 5,049,349 marbles. Toona stole 545,000 of them. she gave 45,000 back, and i dropped 56,980. How many do i have left?
Answer:
The answer is 4,492,369.
Step-by-step explanation:
First of all, how the HECK do you have 5 MILLION MARBLES?! Make the equation for the problem: 5049349 - 545000 + 45000 - 56980.
5049349 - 545000 + 45000 - 56980

The weight of a giant panda is 10 times the weight of a red panda. The combined weight of the pandas is 220 pounds. What is the weight of each panda?
Answer:
The weight of a giant panda = x = 200 pounds
The weight of a red panda = y = 20 pounds
Step-by-step explanation:
Let
The weight of a giant panda = x
The weight of a red panda = y
The weight of a giant panda is 10 times the weight of a red panda.
x = 10y
The combined weight of the pandas is 220 pounds.
x + y = 220
We substitute 10 y for x
10y + y = 220
11y = 220
y = 220/11
y = 20 pounds
Solving for x
x = 10y
x = 10 × 20
x = 220 pounds
Hence:
The weight of each panda is:
The weight of a giant panda = x = 200 pounds
The weight of a red panda = y = 20 pounds

Find the domain and range of each relation. Then determine if the relation is a function. D={-2, -1, 3, 5}, R={-7 ,0 ,4} Function?
Answer:
[tex]D = \{-2,-1,3,5\}[/tex] -- Domain
[tex]R = \{-7,0,4\}[/tex] -- Range
It is a function
Step-by-step explanation:
Given
[tex]D = \{-2,-1,3,5\}[/tex]
[tex]R = \{-7,0,4\}[/tex]
Required
State the domain and range
Determine if the relation is a function
From the question, we have the domain and range as:
[tex]D = \{-2,-1,3,5\}[/tex] -- Domain
[tex]R = \{-7,0,4\}[/tex] -- Range
Next, is to determine if the relation is a function or not.
Yes, it is a function.
The number of elements in the domain is 4
The number of elements in the range is 3
When the domain has more elements than the range, this is called a many-to-one function, and it is a valid type of function.

Sinah bought some packs of gum. There were 8 sticks of gum in each pack. She gave 12 sticks of gum to manuela. This left sinah with 28 sticks of gum. Which equation can be used to represent this situation where g is the number of packs of gum that sinah bought?
Answer:
8g = 12 + 28
g = 5 packs
Step-by-step explanation:
Share of the sticks of gum
Manuela = 12 sticks
Sinah = 28 sticks
There are 8 sticks in each pack
g = number of packs of gum that sinah bought?
g × 8 sticks = 12 sticks + 28 sticks
8g = 40
Divide both sides by 8
g = 40 / 8
g = 5 packs

Diego was asked to plot these points: (−50,0) ( − 50 , 0 ) , (150,100) ( 150 , 100 ) , (200,−100) ( 200 , − 100 ) , (350,50) ( 350 , 50 ) , (−250,0) ( − 250 , 0 ) . What interval could he use for each axis?
Answer:
We have the points:
(-50, 0)
(150, 100)
(200, -100)
(350, 50)
(-250, 0)
First, we need to find the smallest and largest values of the x-component.
The smallest value is x = -250
The largest value is x = 350
Then the interval that we choose for the x-axis should include these two values (so we can plot the points)
Then we need to use, at least, the interval [-250, 350] (A interval that is a little bit larger than that will be easier to read, but that is the minimum he needs to do the plot)
Now let's do the same with the values of the y-components.
The smallest value is y = - 100
The largest value is y = 100
Then the vertical interval should be [-100, 100] or a little bit larger, like in the horizontal case.
We also can see that the values of x and y seem to jump in multiples of 50, then each unit of the grid could represent 50 units, so it is easier to plot. (These are also called intervals, and also theses will depend on each individual axis, but in this case we could use the same for both of them, because it works well for both axis)
Use an interval of 50, because all the
coordinates involve points that are greater than 50 and multiples of 50.
Lily drives 90 miles in 2 hours. If she drives at the same rate, how far does lily travel in each of the following time intervals: 1 hour, 1/2 hour, and 3 hours? Please solve in at least two different ways. You could make a bar model, double number line, ratio table, or graph.
How far does she travel in 1/2 hour?
Answer:
22.5 miles 1/2 hour - 45 miles 1 hour - 67.5 miles 1.5 hours - 135 miles 3 hours
Step-by-step explanation:
If Lily travels 90mph in 2 hours she would travel 45mph each hour. So now just take 45 times 1, 1.5, and 3 to get your answers. So in half an hour she would travel 22.5 miles

If you multiply or divide both sides of an inequality by a negative number, you must __________ the inequality sign.
A
double
B
reverse
C
subtract
D
add an equal sign to
Answer:
B
Step-by-step explanation:
When you multiply both sides by a negative value you make the side that is greater have a larger negative number, which actually means it is now less than the other side. This is why you mathematically have to flip the sign whenever you multiply by a negative number.
