There are 91 in total. Since there are 21 red cars, it would give you 21/91. Around a 23.07% chance.
Answer:
![9 + n](https://tex.z-dn.net/?f=9%20%2B%20n)
Step-by-step explanation:
Well it's an arythmetic sequence, so it will look like:
![a + d\cdot n](https://tex.z-dn.net/?f=a%20%2B%20d%5Ccdot%20n)
Note that the first element is:
![a + d\cdot 1](https://tex.z-dn.net/?f=a%20%2B%20d%5Ccdot%201)
and the second element is:
![a + d \cdot 2](https://tex.z-dn.net/?f=a%20%2B%20d%20%5Ccdot%202)
So the difference between the two gives us d!
![d = 11 - 10 = 1](https://tex.z-dn.net/?f=d%20%3D%2011%20-%2010%20%3D%201)
Now let's find the
:
![a + d\cdot 1 = 10\\a + 1 \cdot 1 = 10\\a + 1 = 10\\a = 9](https://tex.z-dn.net/?f=a%20%2B%20d%5Ccdot%201%20%3D%2010%5C%5Ca%20%2B%201%20%5Ccdot%201%20%3D%2010%5C%5Ca%20%2B%201%20%3D%2010%5C%5Ca%20%3D%209)
Answer:
Area = 84 in²
Step-by-step explanation:
In order to find the area of the rectangle, you need to first set up an equation to find the length based on the information already given in the problem. Since the perimeter = 40 and the formula to find perimeter of a rectangle is: P = 2W + 2L, where W = width and L=Length, we can solve for 'L' by putting in the values given:
P = 2W + 2L or 40 = 2W + 2(3W - 4)
The length of the rectangle is '4 less than 3 times the width'. This can be written as the expression '3W - 4'.
Distribute: 40 = 2W + 2(3W - 4) or 40 = 2W + 6W - 8
Combine like terms: 40 = 8W - 8
Add '8' to both sides: 40 + 8 = 8W - 8 + 8 or 48 = 8W
Divide both sides by '8': 48/8 = 8W/8 or 6 = W
Solve for L: 3W - 4 or 3(6) - 4 = 18 - 4 = 14
Since L=14 and W = 6, we can solve for Area using the formula: A = LxW or A = (14)(16) = 84in².
Answer:
X is 3
Step-by-step explanation:
this is because you divide 3 by nine and it equal 3 therefore x equals 3
Answer:
{0}
Step-by-step explanation:
|n/6| + 1 = 1
Subtract 1 from each side
|n/6| + 1-1 = 1-1
|n/6| =0
Since this is equal to zero what is inside the absolute value must equal zero
n/6 =0
n =0
