We need the exponents law
So if
a=3
b=1/2
then
where x represent every half a year.
The formula is (2)(n-4) = n-1/4
Mult both sides by 4:
8n - 32 = 4n -1, or 4n = 31, or n=31/4.
If this is not what you expected, please ensure that you have copied down the original problem correctly. What do you mean by "1/4 less?"
Let's try (2)(n-4) = 1n-(1/4)n = (3/4)n. Then,
2n-8 = (3/4)n, or (5/4)n = 8. Mult. both sides by (4/5), we get:
n = (5/4)(8) = 10. Is that what you were hoping for?
Answer:
1, 1/2, 3/2
Step-by-step explanation:
This is a prism (a 3d rectangle) and so your formula for finding the volume is V= L x W x H.
For the prism:
L= 1 (4 cubes x 1/4 = 4)
W = 1/2 (2 cubes x 1/4 = 1/2)
H = 3/2 (6 cubes x 1/4 = 6/4 = 3/2)
That's your answer, the tile 1, 1/2, 3/2
Answer:
It will be worth $128.
Step-by-step explanation:
After 1 year, 3/5 of 800 is 480 which leaves the value at $320, and then after 2 years, 3/5 of 320 is 192. 320-192 leaves the value at $128.
Cost per gallon is found by dividing the cost by the number of gallons.
$43.95/16.1 ≈ $2.7298137
Rounded to hundredths, this is $2.73.
