If the center thickness of a Tootsie Roll Pop varies more than 0.2 cm from the target thickness of 7.5 cm, the pop must be throw
GaryK [48]

Answer:

The extreme acceptable sizes for the center thickness of a Tootsie Roll are

x = 7.7 cm and x = 7.3 cm

Step-by-step explanation:

We are given the target thickness as 7.5 cm and the maximum variation as ±0.2

Therefore, the absolute value for the thickness of Tootsie Roll Pop is given for a thickness, x as follows;

\left |x - 7.5  \right | = 0.2

Therefore,

x - 7.5 = 0.2                                        or              x - 7.5 = -0.2

x = 7.5 + 0.2 = 7.7                                                x = 7.5 + (-0.2) = 7.5 - 0.2

x = 7.7 cm                                                                  x = 7.3 cm

Therefore, the extreme acceptable sizes for the center thickness of a Tootsie Roll are

x = 7.7 cm and x = 7.3 cm

Question
sp2606 [1]

Given:

CH = 3960 miles

Altitude = 240 miles

To find:

The distance from the space station to the horizon.

Solution:

The reference image for answer is attached below.

Radius = 3960 miles

CD = CH = 3960

ED = 240

EC = CD + ED

     = 3960 + 240

EC = 4200 miles

By Pythagorean theorem:

E C^{2}=E H^{2}+C H^{2}

4200^{2}=E H^{2}+3960^{2}

17640000=E H^{2}+15681600

Subtract 15681600 from both sides.

17640000-15681600=E H^{2}+15681600-15681600

1958400=E H^{2}

Taking square root on both sides, we get

$1399.428=EH

$1400 \approx  EH

The distance from space station to the horizon is approximately 1400 miles.
