Answer:
240
Step-by-step explanation:
So here’s the step by step (for the show your work thingy)
so we can write an equation
0.05x=12
We use 0.05 becuase 5 percent is basically 5/100 and the x is used becuase we don’t know what the number is and the =12 is for the number that came out as a final result
ow we can solve the equation
x=12/0/05
x=240
Final answer is 240
Answer:
Step-by-step explanation:
An exponential function is of the form

where a is the initial value and b is the growth/decay rate. Our initial value is 64. That's easy to plug in. It goes in for a. So the first choice is out. Considering b now...
If the rate is decreasing at .5% per week, this means it still retains a rate of
100% - .5% = 99.5%
which is .995 in decimal form.
b is a rate of decay when it is greater than 0 but less than 1; b is a growth rate when it is greater than 1. .995 is less than 1 so it is a rate of decay. The exponential function is, in terms of t,

Answer: 39.2 minutes
Step-by-step explanation:
Angela used 56minutes. Brain used 70% of Angela's time which will be 70% of 56.
70/100 × 56 = 39.2 minutes.
Therefore, Brian used 39.2 minutes for the test.
2867.5 is bigger
Even though they both show 5 numbers, the second one has only one decimal place versus 2 on the first
If you ignore the decimal, your left with
290 vs 2867
2867 is much bigger than 290 so this is the answer
Answer:
16
Step-by-step explanation
6 = x/4 + 2
subtract 2 from both sides
4 = x/ 4
since its dividing x and 4 you need to multiply 4 on both sides
16 = x
