Rick traveled 23 of the way from his parents' house to his college dorm. He has driven 294 miles. What is the total distance bet

dimulka [17.4K]

Answer:

441 miles

Step-by-step explanation:

Rick traveled $\frac{2}{3}$ of the way from his parents' house to his college dorm. He has driven 294 miles.

This means that

$\dfrac{2}{3} \text{ of the way is } 294 \text{ miles}$

Then

$\dfrac{1}{3} \text{ of the way is } 294\div 2=147 \text{ miles}$

and

$\dfrac{3}{3} \text{ of the way is } 294+147=441 \text{ miles}$

If the acceleration of an object is given by dv/dt = −2v, Find the position function s(t) if v(0) = 7 and s(0) = 0.

kirill [66]

Answer:

Step-by-step explanation:

Given that acceleration of an object is

$\frac{dv}{dt} =-2v\\\frac{dv}{v} =-2dt\\ln v = -2t+C\\$

is the solution to the differential equation

Since v(0) =7

we get ln 7 = C

Hence $lnv = -2t+ln 7\\v=7e^{-2t}$

since velocity is rate of change of distance s we have

$v=\frac{ds}{dt} =7e^{-2t}\\s= [tex]s(t) =\frac{-7}{2} (e^{-2t})+C)[$

substitute t=0 and s=0

$C=7/2$

So solution for distance is

$s(t) =\frac{-7}{2} (e^{-2t}-1)$

What is the width of a rectangle that has an area of 10 ft.² and a length of 24 inches give your answer in feet

VladimirAG [237]

Answer:

Width = 5 ft

Step-by-step explanation:

A=wl

10 = wl

24 inches = 2 ft

10 = $w*2$

$10/2=w*2/2\\5=w$

Alex gets paid $2.25 a tree for tree planting up north. In one week, he planted 437 trees. What is his wage?

Amiraneli [1.4K]

Answer:

Hey Beebzie

Dang he part of 20m trees? And is Alex a he or she, we'll never know, so I'll just refer to Alex as "it" to not gender appropriate anyone.

So it gets paid 2.25 for one tree. It planted 437 tress.

We take 2.25 x 437 to know the amount of money earned for all trees it planted.

The answer is $983.25, or A. I don't want to gender appropriate the letter "A" either because it could be option 1 or a different letter so I'll just say the answer again to not be sexist, $983.25
