Answer:
<h2>1976 cm <em>2</em>
</h2>
Step-by-step explanation:
Let the length of the rectangle be=l
So, breadth is b=l−14
Perimetre= 2(l+b)=2(l+l−14)=180 cm
⟹4l−28=180cm
⟹l=52cm
And, b=52−14=38cm
Hence, Area=l×b=52×38=1976cm

The answer is: there is 89.2% of the dog food remaining.
Step-by-step explanation:
Given: 31 1/4 lbs of dog food.
In one week - 3 1/8 lbs was used.
To find the amount left, subtract:
31 1/4 - 3 1/8 =
30 5/4 - 3 1/8 =
30 10/8 - 3/8 =
27 7/8 remaining.
To find the percent left, divide:
27 7/8 / 31 1/4 =
27.875 / 31.25 = .892.
Multiply by 100 to get percent:
.892 * 100 = 89.2% remaining.
Hope this helps!! Have an Awesome day!!! :-)
Let n represent the number.
<span>.. (3/5)n - 1 = 23 ... three-fifths of a number decreased by one is twenty-three. </span>
<span>Please note that the same English description might be interpreted as </span>
<span>.. (3/5)(n-1) = 23. </span>
<span>We'll use the first interpretation, as it results in the number being an integer. </span>
<span>.. (3/5)n = 24 ... add 1 </span>
<span>.. n = (5/3)*24 ... multiply by 5/3 </span>
<span>.. n = 40 ... carry out the multiplication </span>
<span>The number is 40.</span>
This is the number of combinations of 5 from 11.
11C5 = 11! / 5!6!
a quick way to work it out is (11*10*9*8*7) / (5*4*3*2*1)
= 462 answer
