Answer:
r=9/2 or 4.5
Step-by-step explanation:
First of all our goal is to get R by itself
by cross multiplying we get,
(r+3)*3=5r
by distributive property we get
3r+9=5r
substracting 3r from both sides we get
9=2r
by dividing by 2 in both sides we get
r=9/2 or 4.5
One bottle has a height of 12 centimeters or 12 cm. Let
us call this h1, so h1 = 12 cm
While the other bottle has a height of 15 centimeters or
15 cm. Let us call this h2, so h2 = 15 cm
The difference in height can be calculated by subtracting
the smaller number from the bigger number, therefore:
difference in height = h2 – h1
difference in height = 15 cm – 12 cm
difference in height = 3 cm
We know that in 1 meter there is:
1 meter = 100 centimeters = 1000 millimeters
Therefore,
difference in height = 3 cm (1000 millimeters / 100
centimeters)
difference in height = 30 mm
