Answer:
C) 3(x + 3y + 5)
D) 3x + 3(3y +5)
Answer:
$23.42
Step-by-step explanation:
- To find the sales tax, you need to 6.5% of $21.99
- To do this you have to times need to turn 6.5% into a decimal, which is 0.065 (i moved decimal point 2 numbers to the left)
- then you do 0.065 × 21.99 which equals 1.42935
- now you have to add 21.99 with 1.42935 = 23.41935
- because of the context of the question, you need the answer needs to be rounded up to the nearest hundredth.
- making the answer $23.42 total
1) his time would have to be less than 11.54
2)each member would have to run a time of about 11.91
3) Assuming that Dwane ran a time of 11.53 the average amount of time it took each member to run the 100 meters will be about 12.2 seconds per 100 meters
(5/3)^-4 * (5/3)^-5 = (5/3)^(-5-4) = (5/3)^-9
(5/3)^-9 = (5/3)^3x
So -9 = 3x
x = -3 answer
The total would be $2.73.
