The length of a rectangular poster is 7 in greater than the width the perimeter is 114 find the width and length?

Let the width be x and the length be x+7:
2(x+x+7) = 114
4x+14 = 114
4x = 114-14
4x = 100
x = 25
Therefore: width = 25 units and length = 32 units

72 is 36 percent of what number?
The Answer is 2520 No it is not--- to find the answer first convert the % to a decimal so 36% would look like 36. and THEN move the decimal over 2 spaces to the left (this is just a rule to remember) 36% is the same as .36 Then simply multiply by the number given so 36% of 72 would look like .36 * 72 and the answer is 25.92 A tip to remember is that 100% of a number is THE SAME NUMBER so 100% of 72 is 72 So if you are looking for 36% (which is less than 100%) your answer will obviously be less than the original number (in this case less than 72)--so obviously the poster who says the answer is 2520 is incorrect same for the opposite direction--if you are looking for 200% (greater than 100%) of a number your answer will be GREATER than the original number--so usually on multiple choice math tests you can eliminate 2 of the options right off the bat by simply applying that tip to them.
How do you figure percentage of keystrokes accuracy?
Accuracy % = ((keystrokes - errors) / keystrokes) * 100 Example: 500 keystrokes - 25 errors = 475 accurate keystrokes 95% = ((500 - 25) / 500) * 100 = (475 / 500) * 100) = .95 * 100 Check: 500 keystrokes - 25 errors = 475 accurate keystrokes 500 keystrokes * 95% accuracy = 500 * .95 = 475 accurate keystrokes 475=475=true! --------------------------- Original Poster's Method: --------------------------- number of mistakes divided by the number of keystrokes multiply by 100 subtract from 100
Find the equation of a circle if the circle is tangent to the line -x y40 and the center is on the line x 2y30?
The equation of a circle is equal to: (x - a)2 + (y - b)2 = r2 Where (a, b) is equal to the center of the circle and r = radius. To understand more why this is the equation of a circle, think of a circle with a known center point (a,b). A circle, by definition, is the set of all points an equal distance from a given point (the center). That distance is also known as the radius. So if only we had some formula to calculate the radius, we would have our equation. Luckily we do. In your circle, imagine a right triangle with the hypotenuse being the radius (wikipedia has a good picture of this at http://en.wikipedia.org/wiki/Circle). Using the pythagorean theorem we have a formula for calculating the radius. Remember that the theorem states that: a2 + b2 = c2 Where a and b are the lengths of the two sides of the right triange adjacent to the right angle and c is the hypotenuse. For a circle with a center point at the origin, the length of the two sides a and b are simply x and y; howver if the center is not at the origin the length of each adjacent side is (x-a) and (y-b) (again draw the circle and triangle out or refer to the wikipedia drawing to better see this). Since c = radius, we now can substitute in and get: (x - a)2 + (y - b)2 = r2 Which we know is the equation of a circle In this problem, we don't know the exact center point or radius yet, we only know the equations of lines that intersect the center and are tangent to the circle. From my memory, this problem needs at least one more piece of information (the radius) before it can be solved. If someone else knows how to do this without the radius, please have at it; otherwise (to the poster) double check to make sure the problem you have did not specify a radius.
What is perimeter of a rectangular poster?
2*(L+W) where L is the length and W is the width of the poster
A poster is 3 feet long and 6 feet widew hat is the perimeter of the poster in feet?
The perimeter of a rectangular shape such as a poster is 2 x length + 2 x width. In this example the perimeter = (2 x 3) + (2 x 6) = 6 + 12 = 18 feet
The width of a rectangular poster is half it length. the area of the poster is 128 square feet what is the length of the poster?
16
Poster that had a length of 13 inchesA perimeter of 61 inches what is the width pichure frame?
17.5 inches
Answer this a piece of poster has a perimeter of 130 cm what are the dimensions of the poster if its length is 35 cm longer than its width?
Suppose the width is W cm Then the length, L = W + 35 cm And the perimeter is 2W + 2L = 2W + 2(W+35) = 4W + 70 4W + 70 = 130 so that 4W = 60 or W = 15 and then L = W + 35 = 50 So the poster is 15 cm by 50 cm
If the width of a rectangular poster is half its length and the area of the poster is 128 square feet what is the width of the poster?
L = 2W 2W x W = 128 2W squared = 128 w squared = 64 W = 8 Width 8 ft, length 16 ft 8 x 16 = 128 QED
The width of a rectangular poster is half its length The area of the poster is 128 square feet What is the length of the poster?
Let the width be x/2 and the length be x: (x/2)*x = 128 Multiply both sides by 2 and remove the brackets: x2 = 256 Square root both sides: x = 16 Therefore: length = 16 feet and width = 8 feet Check: 16*8 = 128 square feet
