Given:
trap door = 130 square feet.
1st item: 6ft 5in wide & 8ft 9in long
⇒ (6ft * 12 in) + 5 in & (8ft *12 in) + 9 in
⇒ 77inches by 105 inches
⇒ 8,085 square inches
2nd item: 13ft 4in wide & 7ft 8in long
⇒ (13ft * 12in)+ 4 in & (7ft *12in) + 8 in
⇒ 160 inches by 92 inches
⇒ 14,720 square inches
3rd item: 5ft 6in wide & 12ft 4in long
⇒ (5 ft * 12in) + 6 in & (12ft * 12in) + 4in
⇒ 66 inches by 148 inches
⇒ 9,768 square inches
130 square feet convert to square inches.
130 sq. ft * 144 sq.in/sq.ft = 18,720 sq. in
18,720 sq. in / 160 inches = 117 inches
Length = 160 inches ; Width = 117 inches
Perimeter = 2(160 + 117)
P = 2(277)
P = 554 inches
Answer:

To find: Unit rate
Unit rate is the part of book completed in one hour.
So, we use unitary method to determine the unit rate.
Unit rate is given as:
On dividing 2 fractions, the division changes to multiplication and the second fraction is reversed. This gives,
Therefore, the unit rate is books per hour
Common base width is the variation from the width to the base.
Answer:
each taco costs $3
t = (23-2)➗(4+7)
Step-by-step explanation:
t represents the cost of one taco
23 is the total cost and 2 is the cost of the salse, the 3 is how many tacos you got and the 4 is how many your friend got.

Answer:
D. 9 vases and 13 teapots
Step-by-step explanation:
From the information given, you can write the following equations:
x+y=22 (1)
5x+9y=162 (2)
x=number of vases
y= number of teapots
First, you have to isolate x in (1):
x=22-y (3)
Then, you have to replace (3) in (2) and isolate "y":
5(22-y)+9y=162
110-5y+9y=162
110+4y=162
4y=162-110
y=52/4
y=13
Now, you can replace the value of y in (3):
x=22-y
x=22-13
x=9
According to this, the answer is that Tim made 9 vases and 13 teapots.
