ANTONII [103]4 years ago
4 0

Answer:

14 meters

Step-by-step explanation:

The area of a rectangle is given by

A = l*w

45 = l*9

Divide each side by 9

45/9 = 9l/9

5 =l

We want the sum of the length and width

w+l = 9+5  =14

lidiya [134]

Answer:

the fraction of the USB drive when one video file use is 10%

Step-by-step explanation:

The computation of the fraction of the USB drive when one video file use is given below:

= USB drive × number of video file ÷ number of video file

= half × 1 ÷ 5

= 0.5 × 1 ÷ 5

= 0.10

= 10%

Hence, the fraction of the USB drive when one video file use is 10%

The pipe fitting industry had 546.5 thousand jobs in 2015 and is expected to decline at an average rate of 3 thousand jobs per y
lesya692 [45]

Answer:

The amount of jobs from fitting industry shall decline in 5.5 percent from 2015 to 2025.

Step-by-step explanation:

Due to the assumption of a yearly average rate, a linear function model shall be used. The expected amount of jobs (n) after a certain amount of years (t) is given by the following formula:

n = n_{o} + \frac{\Delta n}{\Delta t}\cdot t

Where:

n_{o} - Initial amount of jobs in pipe fitting industry, measured in thousands.

\frac{\Delta n}{\Delta t} - Average yearly rate, measured in thousands per year. (A decline is indicated by a negative sign)

If n_{o} = 546.5, t = 2025-2015 = 10\,years and \frac{\Delta n}{\Delta t} = -3\,\frac{1}{years}, then:

n = 546.5+\left(-3\,\frac{1}{year}\right)\cdot (10\,years)

n = 516.5

The percent change in jobs from pipe fitting industry is calculated as follows:

\%n = \left(1-\frac{n}{n_{o}}\right)\times 100\,\%

\% n = \left(1-\frac{516.5}{546.5}\right)\times 100\,\%

\%n = 5.5\,\%

The amount of jobs from fitting industry shall decline in 5.5 percent from 2015 to 2025.
