Answer:
The width of the rectangle is 5 meters, while the length of the rectangle is 12 meters.
Step-by-step explanation:
Given that the perimeter of a rectangle is twice the sum of its lenght and its width, and the perimeter is 34 meters and its lenght is 2 meters more than twice its width, to determine the length and width of the rectangle the following calculation must be done:
(2X + 2 + X) x 2 = 34
(3X + 2) x 2 = 34
6X + 4 = 34
6X = 34 - 4
X = 30/6
X = 5
(2x5 + 2 + 5) x 2 = 34
(10 + 2 + 5) x 2 = 34
17 x 2 = 34
34 = 34
Therefore, the width of the rectangle is 5 meters, while the length of the rectangle is 12 meters.
It’s 4 inches long on the map.

Answer:
A 61377
B 87405
Step-by-step explanation:
If sum of the digits of a number is divisible by 3, then that number is also divisible by 3.
Option A:
Given number is: 61377
Sum of the digits = 6+1+3+7+7 = 24
24 is divisible by 3, hence 61377 is also divisible by 3.
Option B:
Given number is: 87405
Sum of the digits = 8+7+4+0+5 = 24
24 is divisible by 3, hence 87405 is also divisible by 3.
Option C:
Given number is: 30898
Sum of the digits = 3+0+8+9+8 = 28
28 is not divisible by 3, hence 30898 is also not divisible by 3.
Similarly, sum of the digits of the numbers in options D, E and F are 8, 22 and 26 respectively, which are not divisible by 3, hence the numbers 6020, 29830 and 75932 are also not divisible by 3.
Answer: 8 weeks
Step-by-step explanation:
He originally had $315 in his account. This figure increased to $955. It therefore increased by:
= 955 - 315
= $640
If he deposited $80 every week, the number of weeks it would take to deposit $640 is:
= 640/80
= 8 weeks
