Answer:
Should be 39 years.
there is 12 inches in a foot. and if the tree grows 4 inches every year, then in 3 years the tree would be 1 foot. 13 x 3 = 39, thus proving that in 39 years, it will be 13 feet tall. I may be wrong but this sounds correct.
Answer:
12 * 24 * 17 = 4896
10 * 12 * 4 = 480
4896 + 480 = 5376
the volume is 5376 cubic inches.
Answer: 0.125 mg per half minute
Step-by-step explanation:
15mg per hour can be written as 15mg/h
To find out how many mg of medication are delivered per half minute you can convert from hour to minutes
There are 60 minutes in 1 hour, so you can use the conversion factor (1h/60 min) and multiply the expression by it
15 mg/h (1h/60min) = 0.25 mg/min
But the question is per half minute so you have to multiply and divide the previous expression by 0.5 (To obtain 0.5 min in the denominator, which is half minute)
Then,
(0.25 mg/min ) (0.5/0.5) = 0.125 mg/ 0.5 min (0.125 mg per half minute)
= 16 * 10^13
which in scientific notation is 1.6 * 10^14
Since the value of b is 5, hence the equation of the horizontal line is x = 5
<h3>Equation of a line</h3>
A line is defined as the shortest distance between two points. The given line on the xy plane is a horizontal line.
The equation of a line is expressed as y = mx + b where;
m is the slope
b is the y -intercept
The equation of a horizontal line on the other hand is expressed as x = b
where b is the point where the horizontal line crosses the y-axis.
Since the value of b is 5, hence the equation of the horizontal line is x = 5
