Answer: it is the one with c
Step-by-step explanation:
So, if a long distance call costs 21 cents we just use a formula first we do 20 - 9.92, which gives us 10.08, then we divide it like this: 10.08 / 0.21, which gives 48! So, Lashonda spent 48 minutes making a long distance call! Hope this helped! Brainliest is always appreciated.
Let
d = the total number of dairy cattle
b = the total number of beef cattle
2/3 of the dairy cattle on a farm are in the barn, and we know that 24 dairy cattle are in the barn thus:
(2/3)d = 24
d = 36 dairy cattle
1/4 of the beef cattle are in the barn and there are 16 beef cattle in the barn thus:
(1/4)b = 16
b = 64 beef cattle
64 - 36 = 28
There are 28 more beef cattle on the farm than dairy cattle.
The half life of the radioactive isotope to the nearest tenth is 0.83 days.
<h3>What is rate of radioactive decay?</h3>
The rate of radioactive decay is the rate at which a radioactive isotope is disintegrated. The half life is the time taken for half of the original amount of radioactive isotope to remain.
Given that;
t/12 = 0.693/k
Where;
t1/2 - half life
k =decay constant
t/12 = 0.693/0.84
t/12 = 0.83 days

Answer: $4.76
To find the answer you need to find out the total before the 20% tips to find this you need to subtract 14.40 and 20% which = $11.52.If the coffee was $2 you also need to subtract that so the equation would be (11.52-2.00=9.52).Lastly the question is asking you for the price of one serving of pancakes but we have the answer for 2 which is $9.52.To find the price of of 1 serving you need to divide $9.52 by 2 = $4.76.So your answer is $4.76 for 1 serving of pancakes.
