She added the numerators
instead of multiplying them
you should also simplify the final answer
the correct answer would be -3 1/8 or -25/8 as an improper fraction.
X/28 = 5/7
x = 28 * 5 / 7
x = 20
answer
x = 20 ft
Answer:
-4;-4
Step-by-step explanation:
these would be the coords because each of the lines represents 2 units
Answer:
Step-by-step explanation:
Answer:
16.34 hours
Step-by-step explanation:
According to the given information we can see that the case is of exponential growth
Hence, we will use the formula

Here A =800 is the amount that is needed to reach
P is the initial amount that is 500
We have to find the time it will take to reach 800 that is we need to find t
On substituting the values in the formula we get

On simplification we get

Taking log on both sides we get

using 
And 

Now substituting values of log 8=0.903, log 5=0.698 and log 2=0.301 we get
