Answer:
your answer should be 37:7
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 777 and 147 is 21
Divide both terms by the GCF, 21:
777 ÷ 21 = 37
147 ÷ 21 = 7
The ratio 777 : 147 can be reduced to lowest terms by dividing both terms by the GCF = 21 :
777 : 147 = 37 : 7
Therefore:
777 : 147 = 37 : 7
Answer: It will take 6 years for 7500 grams of X to reach 6900 grams.
Step-by-step explanation:
Expression for rate law for first order kinetics is given by:

where,
k = rate constant
t = age of sample
a = let initial amount of the reactant
a - x = amount left after decay process
a) for completion of half life:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.


b) for 7500 g to reach to 6900 g


It will take 6 years for 7500 grams of X to reach 6900 grams.
Answer:
the answer would be anything 11 and under (11,10,9,8,7,6,5,4,3,2,1,0)
Step-by-step explanation:
This is because if n+5 is less than or equal to 16 then 11+5=16 so that is equal to and less than would be using any number less than 11
hope this helps ;)
Answer:
191
Step-by-step explanation:
The amount spent for a single text: 177/17,7=0,1
x×0,1=19,1
x=19,1/0,1
x=191
