Since rectangles have two pairs of equal-length sides, for any rectangle with length L and width W, its perimeter is always 2L + 2W (or 2(L + w), whichever you prefer). Here, we're told that the width is 4 feet less than the length. Symbolically, we'd say that W = L - 4. This allows us to write the perimeter entirely in terms of length if we replace our W with the expression on the right side:
2L + 2W = 2l + 2(L - 4) = 2L +2L - 8 = 4L - 8
Sam wants this expression to come out to 52, so we can set up the equality 4L - 8 = 52 and solve for L to find what the length has to be:
Adding 8 to either side, the equality becomes 4L = 60. Diving either side by 4 gives us L = 15, which tells us that the length of the deck should be 15 feet.
Answer:
Step-by-step explanation:
Solve for x:
To solve this inequality, we must minus 5 from both of the sides.
This equals
Now we'll make this into a fraction and divide both sides by -2.
After we divided, we got our answer.
Hope this helps!
80% of 860 is 688
860 x 0.8 =
688
Answer:
Infinite number
Step-by-step explanation:
we know that
If one angle is 90°, and another half of that, then it must be 45° and so the third angle is also 45°. (The sum of the internal angles of a triangle must be equal to 180 degrees)
Remember that
If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
therefore
There is an infinite number of unique triangle with these angles.
Answer: The required percentage is 33.02%.
Step-by-step explanation: Given that a bookstore owner is having a sale. The book Bart wants was originally priced at $14.99 the book is now $10.04.
We are to find the percentage by which the price was reduced.
The price by which the price of the book reduced is given by
R.P. = $(14.99 - 10.04) = $4.95.
Therefore, the percentage by which the price of the book reduced is given by
Thus, the required percentage is 33.02%.
