Answer:
1890, total cost of lights per week
Step-by-step explanation:
The lights cost 45 dollars per bulb and 6 go out per day, 45×6=270
270 is the cost to replace the bulbs of one day.
270×7=1890. 1890 is the cost for a whole weeks worth of replacing these bulbs.
Answer:
$110.88
Step-by-step explanation:
Let L be the length of the first fence surrounding the garden and P its perimeter.
For a square, P = 4L,
So, L = P/4
Since P = 36 feet,
L = P/4
= 36/4
= 9 feet
Let L' be the length of the second fence. Given that second fence is 3 feet away from the first fence, it follows that L' = L + 3
= 9 + 3
= 12 feet.
So, the perimeter of the second fence is P' = 4L'
= 4 × 12 feet
= 48 feet.
So, the total length of the two fences is P" = P + P'
= 36 feet + 48 feet
= 84 feet
Since the cost of the material to build the two fences is $1.32 per foot, the total cost of the fences is cost per foot × total length of fences = $1.32 × 84 = $110.88
Answer:
25%
Step-by-step explanation:
First find the difference in price= $8-$6 = $2
Now, find percentage decrease in the price of sandwich.
Percentage decrease= (difference in price/ original price) *100
= 
*100
=
Percentage decrease=25%
Answer:
TRUE
Step-by-step explanation:
Answer:
86 degrees
Step-by-step explanation:
For triangle the sum of angles is equal to 180 degrees
so,
x+(x-35)+43=180
2x -35+43=180
2x = 180-43+35
2x = 172
x = 86
