James walked 548 yards. How many miles has he walked ?

One yard is 0.0005 miles,

548 * 0.0005 = 0.274,

So the answer is 0.274 miles.

Hope this helps.

548 * 0.0005 = 0.274,

So the answer is 0.274 miles.

Hope this helps.

Jamie has walked 0.311.

Paula bought a new flotation tank for $8,000. She must pay 5% sales tax and 7% excise tax. The company is shipping the tank, so Paula must also pay a $15 insurance charge. What's the total purchase price of the tank? A. $8,960 B. $8,400 C. $8,560 D. $8,975

$8000 + 5%×$8000 + 7%×$8000 + $15

= $8000 + $400 + $560 + $15

= $8975

The appropriate choice is

D. $8975

= $8000 + $400 + $560 + $15

= $8975

The appropriate choice is

D. $8975

Answer:

D. $8,975

Step-by-step explanation:

8,000 x 5% = 400

8,000 x 7% = 560

8,000 + 400 + 560 + 15 = 8,975

A buoy floating in the sea is bobbing in simple harmonic motion with period 1 second and amplitude 11 in . Its displacement d from sea level at time t=0 seconds is 0in, and initially it moves downward. (Note that downward is the negative direction.)

Answer: incomplete question

Complete question:

A buoy floating in the sea is bobbing in simple harmonic motion with period 1 second and amplitude 11 in . Its displacement d from sea level at time t=0 seconds is 0in, and initially it moves downward. (Note that downward is the negative direction.). Give the equation modelling displacement(d) as a function of time(t)

Answer:

d = -11sin2πt

Step-by-step explanation:

Given,

Amplitude = 11 in

Period = 1 seconds.

Since, d at t = 0 in

Let displacement be d =asin(wt+∅)

So, a = amplitude = -11 in (it moves downward)

w = angular velocity

= 2π/period

= 2π/1

= 2πrad/sec

Therefore, at t = 0

So, since sin(∅) = 0

∅ = 0

So, inputing values of a,∅, and w we get

d = -11sin(2πt + 0)

d = -11sin2πt
