Answer:
$109.71
Step-by-step explanation:
first we find the perimeter
=2(280+200)
=2×480
=960m
now we multiply it by 4 as he wants it 4 times around
960×4
3840
now we find the fencing cost
since 35 per meter we divide it by 35
3840/35
=$<u>109.71</u>
Answer:
20
Step-by-step explanation:
16=1 2/10R + -8
16+8= 12/10R
24=12/10R
R=20
35.5 ft is the width of the room
Answer:
35 and 36
Step-by-step explanation:
To solve this problem, we must interpret it line by line;
- We are dealing with consecutive integers; these are integers with a difference of 1 between them.
let the first number = x
second number = x + 1
x
- one - ninth of the second;
(x + 1)
for the "less" ;
x -
(x + 1) = 3
Multiply through by 45
45(
x) - (45)
(x + 1) = 3 x 45
9x - 5(x + 1) = 135
9x - 5x -5 = 135
4x = 135 + 5
4x = 140
x = 35
Now, x+1 = 35 + 1 = 36
The consecutive integers are 35 and 36
