Answer:
Width = 18 inches
Length = 59 inches
Step-by-step explanation:
The length of a rectangle is five more than triple the width. If the perimeter is 154 inches, what are the dimensions
Perimeter of a rectangle = 2L + 2W
The length of a rectangle is five more than triple the width.
L = Length = 5 + 3W
W = Width
If the perimeter is 154 inches, what are the dimensions
Hence,
154 = 2L + 2W
154 = 2(5 + 3W ) + 2W
154 = 10 + 6W + 2W
Collect like terms
154 - 10 = 8W
144 = 8W
W = 144/8
W = 18 inches
Length = 5 + 3W
Length = 5 + 3(18)
Length = 5 + 54
Length = 59 inches

80° is the correct answer
Answer:
<u>Question 12:</u>
1.625
Terminating
<u>Question 13:</u>
.833(repeating)
<u>Question 14:</u>
9m = 900cm
<u>Question 15:</u>
2.3mm = .23cm
Step-by-step explanation:
<h2>Question 12:</h2>
We can convert the mixed number into an improper fraction
<em />
<em>Rule:</em>
<em>denominator * whole number + numerator</em>
13/8
Divide 13 over 8
13/8 = 1.625
<h2>Question 13:</h2>
Divide 5 over 6
5/6 = .833(repeating)
<h2>Question 14:</h2>
<em>There are 100 centimeters in one meter, to get to 9m in cm we'd multiply.</em>
<em />
100 * 9 = 900cm
9m = 900cm
<h2>Question 15:</h2>
<em>One mm is .1 cm, to get to 2.3mm in cm we'd divide by 10.</em>
<em />
2.3/10 = .23
2.3mm = .23cm
