Answer:
a=-4
b=2
c=7
so therefore a*b*c=-4*2*7
Answer:
Prime numbers are whole numbers that has factors of 1 and itself.
Example: 2 is a prime because there is no way you could factor it except 1 and 2.
Composite numbers have more factors which also include 1 and itself.
Example: 50 is composite because it has factors more than 1 and itself.
5 is a factor of 50; 10 is a factor of 50.
So let's begin sorting.
<em>Prime: 7, 11, 31.</em>
Composite: 4, 8, 10, 27.
Hope this helps! :)

Step-by-step explanation:
40% own neither, it means 100% - 40% = 60% own either a dog or a cat.
Since 45% own a dog, 60% - 45% = 15% own a cat but not a dog.
Since 25% own a cat and 15% own only a cat, 25% - 15% = 10% own a dog and a cat.
Now, 10% out of 45% own both pets, 45% - 10% = 35% own only a dog.
<u>All the numbers reflected in the attached Venn diagram:</u>
- 35% - dog
- 10% - both
- 15% - cat
- 40% - neither
Answer:
Step-by-step explanation:
We would apply the formula for exponential decay which is expressed as
A = P(1 - r)^t
Where
A represents the value of the car after t years.
t represents the number of years.
P represents the initial value of the car.
r represents rate of decay.
From the information given,
A = $2700
P = $20300
n = 2004 - 1997 = 7 years
Therefore,
20300 = 2700(1 - r)^7
20300/2700 = (1 - r)^7
7.519 = (1 - r)^7
Taking log of both sides, it becomes
Log 7.519 = 7 log(1 - r)
0.876 = 7 log(1 - r)
Log (1 - r) = 0.876/7 = 0.125
Taking inverse log of both sides, it becomes
10^log1 - r = 10^0.125
1 - r = 1.33
r = 1.33 - 1 = 0.33
The expression would be
A = 20300(1 - 0.33)^t
A = 20300(0.67)^t
Therefore, in 2007,
t = 2007 - 1997 = 10 years
The value would be
A = 20300(0.67)^10
A = $370
Hi there! To turn a mixed number into a improper fraction we multiply 1 by 3 and add 2. 1 2/3=1×3+2/3=5/3. Therefore, 1 2/3 as an improper fraction is 5/3.
