Answer:

The width of 10 lanes would be a total of  10 centimeters , 1 cm for each lane on his drawing.

Step-by-step explanation:

The scale he uses is

15 ft= 3 cm

1 feet = 3/15 cm

1 cm= 15ft/3= 5 ft

One lane = 60 ft long and 5 ft wide

In centimeters it would be 60 ft / 5ft = 12 cm long and 5 ft/5ft= 1 cm wide

The width of 1 lane is 1 cm .

The width of 10 lanes would be a total of  10 centimeters , 1 cm for each lane on his drawing.

Sveta_85 [38]

Answer:

x=amount invested at 7%

2x=amount invested at 8%

3x=amount invested at 9%

interest=principal*rate*time (time=1 year)

$150=0.07x+0.08*2x+0.09*3x

$150=0.07x+0.16x+0.27x

$150=0.50x

$1500=5x

x=$300 invested at 7%

2x=$600 invested at 8%

3x=$900 invested at 9%

What is the slope of a linear that is perpendicular to the line y=-1/2x+5?​
Vlada [557]

Step-by-step explanation:

Equation of given line is:

y =  -  \frac{1}{2} x + 5 \\  \\ equating \: it \: with \: y =m_1x + c  \\ we \: find \:  \\ m_1 = -  \frac{1}{2} \\ let \: m_2 \: be \: the \: slope \: of \: required \: line \\  \\  \therefore \: m_1 \times m_2 =  - 1( \because \: lines \: are \:  \perp) \\  \\ \therefore \: -  \frac{1}{2} \times m_2 =  - 1\\  \\ \therefore \: m_2 = 2 \\

Thus, the slope of required line is 2.
