Answer:
2.9 years
Step-by-step explanation:
Given that :
Half-life t1/2 = 9 years
Initial mass = I = 70 grams
A = final mass = 56 grams
t = time taken to reach final amount
Using the exponential half life relation :
A = I(0.5)^t/t1/2
56 = 70(0.5)^t/9
56/70 = 0.5^t/9
0.8 = 0.5^t/9
Log 0.8 = log 0.5^t/9
−0.096910 = −0.301029 * t/9
t/9 = 0.096910 / 0.301029
t/9 = 0.3219291
t = 0.3219291 * 9
t = 2.8973619
t = 2.9 years
5.9 m
I solved it by adding some of the numbers that were in the picture & then added the m at the end because all of the other had it
Answer:
30 baskets
Step-by-step explanation:
The experimental probability Pa that Amir will make a basket is 0.4;
Pa = 0.4
the experimental probability Pj that juju with make the same basket is 0.6;
Pj = 0.6
Total number of shoot Nt = 150
Number of basket Amir will make is;
Na = Pa × Nt
Na = 0.4 × 150
Na = 60 basket
Number of basket juju will make is;
Nj = Pj × Nt
Nj = 0.6 × 150
Nj = 90 basket
Answer:
7/10*4/10
Step-by-step explanation:
7/10 and 4/10 are both just the fraction forms of the decimal so it should work
Answer:
Step-by-step explanation:
The missing parameters are:
--- Cost of marble countertops
--- Cost of retail markup
Required
The cost of marked up price
This implies that we calculate m(c(a))
We have:
can be written as:
Substitute:
Hence, the cost of marked up price is:
