It would take 5 hours for all the bacteria to die. 1000 divided by 5 is 200 so 200x5=1000

Answer:

$403.15

Step-by-step explanation:

Principal loan amount is the total amount minus down-payment:

$Principal=24000-1000\\\\=23000$

Knowing that $n=12\times 6=72,P=23000, r=7.99\%/12=0.006658$ , the monthly payments can be calculated using the formula:

$M=P[\frac{r(1+r)^n}{(1+r)^n-1}]\\\\=23000\frac{(0.006658(1.006658)^{72}}{1.006658^{72}-1}\\\\=403.15$

Hence, the monthly payment is $403.15

Convert 150 degrees to radian

Dafna1 [17]

Answer:

A

Step-by-step explanation:

To convert degrees to radians

radian measure = degree measure × $\frac{\pi }{180}$

Hence

radian measure = 150° × $\frac{\pi }{180}$

Cancel both 150 and 180 by 30, then

radian measure = 5 × $\frac{\pi }{6}$ = $\frac{5\pi }{6}$
