Answer:
30
Step-by-step explanation:
15cm for 5
5 x 2=10
15 x 2 = 30
The total distance will be 8685.2 kilo meters if she travelled by plane
It looks as though there are 25 21-40 year-olds. 40% of 25 is 10, this is the amount that are AGAINST the increase. Therefore the ones in favor for the increase must be 25 - 10 = 15.
You should be able to follow the same process to get the 41-60 year-olds against an increase. Just be sure to read the given information carefully
The numbers are 3 and 7
Step-by-step explanation:
Let the first number be x and the second number be y
Then according to given statement
One number added to three times another number is 24
x+3y=24 Eqn 1
Five times the first number added to three times to other number is 36
5x+3y=36 Eqn 2
Subtracting Equation 1 from equation 2
Dividing both sides by 4
Putting x=3 in equation 1
Dividing both sides by 3
Hence,
The numbers are 3 and 7

Answer:
X = 48 inches for the shortest side
Step-by-step explanation:
9s = first side
10s = second side
4s = third side
Perimeter = sum of the sides
276 = 9s + 10s + 4s
276 = 23s
276/23 = s
12 = s
9s = first side; 9(12) = 108
10s = second side; 10(12) = 120
4s = third side; 4(12) = 48
