Answer: The length of the rectangle is 13.5 units and the width is 4.5 units
Step-by-step explanation: The perimeter of the rectangle has been given as 36 units. The formula applied to calculate the perimeter is
Perimeter = 2(L + W)
However the details in the question states that the rectangle is three times as long as it is wide. That is, the length is three times it’s width. So if the width is W then the length is 3W.
Therefore, to calculate the perimeter we shall apply the following;
Perimeter = 2(3W + W)
If the perimeter is given as 36 units, then we have;
36 = 2(4W)
We cross multiply and we have
36/2 = 4W
18 = 4W
Divide both sides of the equation by 4
4.5 = W
So the width is calculated as 4.5, hence the length would be 3W which equals 3 x 4.5 and that equals 13.5
Therefore, Length = 13.5 units and Width = 4.5 units
For the first question, triangle ABC is congruent to triangle DEF by the ASA (angle side angle)
For the second question, triangle MNO is congruent to triangle PRQ by the SAS (side angle side)
For the third question, triangle UVW is congruent to triangle XYZ by the SAS (side angle side)
Answer:
Step-by-step explanation:So if he or she answered 12 right and got 80% then if you count to 100% at should be 14 questions I think if i am wrong sorry
12=80%
13=90%
14=100%
Step-by-step explanation:
He goes 20 miles in total so knowing that you can multiply 20 by 6 which is 120. Then you can add the break on giving you 125 min.
Answer:
x = 6
Step-by-step explanation:
Step 1: Write equation
-4x + 6 = 3x - 36
Step 2: Solve for <em>x</em>
- Add 4x to both sides: 6 = 7x - 36
- Add 36 to both sides: 42 = 7x
- Divide both sides by 7: x = 6
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
-4(6) + 6 = 3(6) - 36
-24 + 6 = 18 - 36
-18 = -18
