Answer:
$400
Step-by-step explanation:
If the price after taking 25% off is $300, then $300 is 75% of the original price.
$300 = 0.75p
$300/0.75 = p = $400
The original price was $400.
_____
<em>Check</em>
0.25 × $400 = $100
$400 -100 = $300 . . . . the price after taking 25% off
Answer:
$75000/year
$6250/month
Step-by-step explanation:
1500 ft²*$50/(ft²*year) = $75000/year
1 year = 12 month
$75000/12 month= $6250/month
Answer:
The width of the building is 50 lamps and 60 lamps will be needed.
Step-by-step explanation:
The perimeter is computed by the sum of the sides of the building, since the length and width are equal on the oposite sides of the building, the perimeter is given by:
perimeter = 2*length + 2*width
900 = 2*(400) + 2*width
2*width + 800 = 900
2*width = 900 - 800
2*width = 100
width = 100/2 = 50 feets
To know how many lights bulbs will be needed we need to take the perimeter of the building and divide it by the space between the lamps. We have:
number o lamps = 900/15 = 60 lamps
They are equal
(-16)-(-4)
*negative and negative make a positive
-16+4= -12
-16+4=-12
They both make -12. They both are equal
Answer:
The proportion is p = 0.399
Step-by-step explanation:
The estimate of a proportion is the number of desired outcomes divided by the number of total outcomes.
Desired outcomes:
286 people captured, so D = 286.
Total outcomes:
Sample of 716 suspected criminals, so T = 716.
