A woman sprints at a rate of 19 ft/s. How many minutes will it<br> take her to sprint 600 feet ?

IgorC [24]

Answer:

10/19 min ≈ 0.5263 min

Step-by-step explanation:

The woman's sprinting speed is given in feet per second, and we are asked for it in minutes per 600 feet. To find the time, we can use the relation ...

time = distance / speed

Using the given numbers will give a time in seconds, so we need to do a units conversion to find the answer in minutes.

<h3>setup</h3>

time = distance/speed

time = (600 ft) / (19 ft/s) = (600/19) s

Converting the units gives ...

time = (600/19) s × (1 min)/(60 s) = (600·1)/(19·60) min

<h3>evaluation</h3>

The time it takes the woman to sprint 600 feet will be ...

time = 600/(19·60) min = 10/19 min ≈ 0.5263 min

The acute angle between intersecting lines that do not cross at right angles is the same as the angle determined by vectors norm

PtichkaEL [24]

Answer:

$45^{\circ}$

Step-by-step explanation:

We are given that two lines equation

$x+\sqrt 3y=1$ ...(1)

$(1-\sqrt 3)y+(1+\sqrt 3)y=8$

Compare with the equation of line

ax+by+c=0

$a_1=1,b_1=\sqrt 3$

$a_2=(1-\sqrt 3),b_2=(1+\sqrt 3)$

The angle between two lines =Angle between two vectors

The angle between two vector

$a_1i+b_1j$ and

$a_2i+b_2j$

is given by

$cos\theta=\frac{a_1a_2+b_1b_2}{\sqrt{a^2_1+b^2_1}\sqrt{a^2_2+b^2_2}}$

Using the formula

Therefore, the angle between two lines

$cos\theta=\frac{1(1-\sqrt 3)+\sqrt 3(1+\sqrt 3)}{\sqrt{(1)+(\sqrt 3)^2}\times \sqrt{(1-\sqrt 3)^2+(1+\sqrt 3)^2}}$

$cos\theta=\frac{1-\sqrt 3+\sqrt 3+3}{\sqrt{1+3}\times\sqrt{1+3-2\sqrt 3+1+3+2\sqrt 3}}$

$cos\theta=\frac{4}{2\times\sqrt 8}=\frac{2}{2\sqrt 2}$

$cos\theta=\frac{1}{\sqrt 2}$

$cos\theta=cos45^{\circ}$

By using $cos45^{\circ}=\frac{1}{\sqrt 2}$

$\theta=45^{\circ}$

Hence, the angle between two lines =45 degree
