Write 5% as a decimal.

jolli1 [7]

You cannot do it that way. Make sure the question you wrote is correct, because you would divide 5 by 100, not 100 by 5. A simple way is to move the decimal point two points to the left. 5% as a decimal is 0.05.

The answer is false if the question is written this way.

After heating up in a teapot, a cup of hot water is poured at a temperature of

xxTIMURxx [149]

Answer:

k ≈ 0.060
T(4) ≈ 178 °F

Step-by-step explanation:

The desired formula parameters for Newton's Law of Cooling can be found from the given data. Then the completed formula can be used to find the temperature at the specified time.

__

<h3>Given:</h3>

$T(t)=T_a+(T_0-T_a)e^{-kt}\\\\T_a=68,\ T_0=208,\ (t,T)=(3,185)$

<h3>Find:</h3>

k

T(4)

<h3>Solution:</h3>

Filling in the given numbers, we have ...

185 = 68 +(208 -68)e^(-k·3)

117/140 = e^(-3k) . . . . . subtract 68, divide by 140

ln(117/140) = -3k . . . . . . take natural logarithms

k = ln(117/140)/-3 ≈ 0.060

__

The temperature after 4 minutes is about ...

T(4) = 68 +140e^(-0.060·4) ≈ 68 +140·0.787186

T(4) ≈ 178.205

After 4 minutes, the final temperature is about 178 °F.

Martin has 5/6 of a pizza Liam has four times as much pizza is Martin how much pizza does Liam have? (Put it in a fraction)

djverab [1.8K]

Answer:

The pizza of martin is $\dfrac{4}{5}$

Step-by-step explanation:

Given that,

Martin has $\dfrac{5}{6}$ of pizza.

Liam has four time much pizza.

Let us consider pizza is x.

We need to calculate the how much pizza of martin

Using given data

Pizza of Martin = $x\times\dfrac{5}{6}$

Pizza of Liam = $4\times(\dfrac{5}{6}x)$

The pizza of martin will be

$Pizza\ of\ martin=\dfrac{\dfrac{20}{6}x}{\dfrac{20}{6}x+\dfrac{5}{6}x}$

$Pizza\ of\ martin =\dfrac{4}{5}$

Hence, The pizza of martin is $\dfrac{4}{5}$
