Which is greater 9/16 or 8/15
chubhunter [2.5K]
I find that turning the fractions into decimals helps in this situation.
9/16 = 0.5625
8/15 = 0.5333

so 9/16 is greater then 8/15

The temperature of a cup of coffee varies according to Newton's Law of Cooling: dT dt equals negative k times the quantity T min
Maslowich

Answer:

67.3°C

Step-by-step explanation:

A = 25, T(0) = 100, T(1) = 90, find T(4)

dT/dt = -k(T - A)

d(T - A)/dt = -k(T - A)

d(T - A)/(T - A) = -k dt

ln(T - A) = lnC - kt

T(t) -A=Ce^{-kt}\\T(t) = A + Ce^{-kt} = 25 + Ce^{-kt}\\T(0) = 25 + C = 100\\C=75

T(t) = 25 + 75e^{-kt}\\T(1) = 25 + 75e^{-k} = 90\\75e^{-k} = 65\\e^{-k} = \frac{65}{75}, k = ln\frac{75}{65} = 0.1431\\T(t) = 25+75e^{-0.1431t}\\T(4) = 25+75e^{-0.1431\times4} = 67.3

1)a-19=3 2) y/7=10 3)5g=100 solve please
3241004551 [841]
Are these three different questions? if so:
1: add 19 to both sides to get a = 3 +19
answer: a = 22

2: multiply both sides by 7 to get y = 10 * 7
answer: y = 70

3: divide both sides by 5 to get g = 100/5
answer: g = 20

hope this helped! good luck :)

Ludmilka [50]

The total weekly pay of the company is $754.98

What is total hours worked for the week?

The overtime is the excess of  total hours, which is 47 hours, over the regular hours of 40 hours of work a week, in essence, overtime hours  is 7(47-40)

Overtime rate=regular hour pay*1.5

regular hour pay=$14.95

overtime rate=$14.95*1.5

overtime rate=$22.425

overtime pay for 7 hours=7*$22.425

overtime pay for 7 hours=$156.98

The regular pay is 40 hours of regular time multiplied regular pay per hour

regular pay=$14.95*40

regular pay=$598.00

total pay=regular pay+overtime

total pay=$598.00+$156.98

total pay=$754.98
