Answer:
60 centimeters by 20 centimeters
Step-by-step explanation:
5 X 20 = 100 5 X 60 = 300
Y=4 because every y value is 4 and x is infinite
<span>the dimensions of a door are variable, for effects of this problem we will assume a door height of 210 cm and a door width of 80 cm
Step 1
</span><span>convert the dimensions of the door in cm to inches
</span>we know that
1 in-------------> 2.54 cm
X----------------> 210 cm
X=210/2.54=82.67 in (height)
1 in-------------> 2.54 cm
X----------------> 80 cm
X=80/2.54=31.50 in (width)
the dimensions of a door are 31.50 in x 82.67 in
Step 2
calculate the amount of rules of 12-inches necessary to measure the height of the door
82.67 in (height)
if one rule-------------> measure 12 in
X----------------------> 82.67 in
X=82.67/12=6.8-----------> 7 rules
Step 3
calculate the amount of rules of 12-inches necessary to measure the width of the door
31.50 in (width)
if one rule-------------> measure 12 in
X----------------------> 31.50 in
X=31.50/12=6.8-----------> 2.62 ------------> 3 rules
the answer is
to measure a door are needed about 7 rules of 12-inches for the height and about 3 rules of 12-inches for the width
Answer:
The tree grew 8 and 3/4 inches.
Step-by-step explanation:
To get this answer, first subtract the whole numbers.
21 - 12 = 9
Now do the same with the fractions.
1/8 - 3/8 = -2/8
Now add those two together.
9 - 2/8 = 8 6/8 = 8 3/4
