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
<span>We will start using a new way to indicate simplifying fractions. When a numerator or
a denominator gets simplified, we will cross it out with a slash and write the new
numerator or denominator next to it (either above it or below it).</span><span>The number you divide by (the 4) does not get indicated in any way! You only
think about it in your mind: “I divide 12 by 4, and get 3. I divide 20 by 4, and get 5.”</span><span>You may not see any advantage over the “old” method yet, but this shortcut will
come in handy soon.</span> <span />
Answer: He does have enough.
Explanation: Simplifying 7/8 cups to fourths you get 1 3/4 cups of milk. If he has 2 cups of milk he still would have 1/4 cup left over of milk.
Since we have to solve the given formula for h(height) so, the correct option is (a)
Answer:
$52.44
Step-by-step explanation:
So here is the explanation. $240•.80= 192 (80% as a decimal is .80) 240-192=48. 48•.0925=4.44 which you add 48, and get a sum of $52.44
Hope this helps :)
