Use a calculator to find the value of t. Round to the nearest thousandth. T=ln 1.5-3
spin [16.1K]

Answer:

-2.595

Step-by-step explanation:

When inputting this function into your calculator, we need to be aware of a couple things:

1.) his is ln(1.5) - 3, and not ln(1.5-3). Negative numbers cannot be put into the natural log function.

2.) That is because lnx is another way of saying log_{e}x. If you're having trouble finding ln on the calculator, use logx/loge (an odd rule that you'll learn soon from the looks of it.)

Convert the angle 57°29'38" to decimal degrees and round to the nearest hundredth of a degree.
Daniel [21]
The answer is 57.49°

57°29'38" = <span>57° + 29' + 38"
</span>
1° = 60'
x° = 29'
1 : 60 = x : 29
x = 29 * 1 : 60 = 0.48°
<u>29' = 0.48°</u>

1° = 3600''
x° = 38''
1 : 3600 = x : 38
x = 38 * 1 : 3600
x = 0.01°
<span><u>38'' = 0.01°</u>

</span>
57°29'38" = 57° + 29' + 38" = 57° + 0.48° + 0.01° = 57.49°

Evaluate the required thickness of styrofoam for the freezer compartment in the previous problem when the inside wall is exposed
Murljashka [212]

Step-by-step explanation:

bananas are to be cooled from 24 to 138c at a rate of 215 kg/h by a refrigeration system. the power input to the refrigerator is 1.4 kw. determine the rate of cooling, in kj/ min, and the cop of the refrigerator. the specific heat of banana above freezing is 3.35 kj/kg·8c.

Evaluate the required thickness of styrofoam for the freezer compartment in the previous problem when the inside wall is exposed to air at −10 c through a surface coefficient of 16 w/m2⋅k and the outer wall is exposed to 33 c air with a surface coefficient of 32 w/m2 ⋅ k. determine the surface temperatures for this situation
