Answer:
6666
Step-by-step explanation:
Yes:No =4:7.total=11
4x/11=2424 ;x=6666
4:7 = 8:14
4 x 2 = 8. 7 x 2 = 14
<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 two points are (1,-4) and (1,4)
Step-by-step explanation:
Given that distance between points is 8 units.
Also, Points have the same co-ordinate of x-coordinates.
Let one point be (1,-4)
Distance between two points is given by L=
Putting into the formula,
L=8 and (X1, Y1)=(1,-4) and (X2,Y2)=(1,Y2)
Thus, the two points are (1,-4) and (1,4)
