Answer:
3 n minus 4 represents the expression "four less than three times a number"
Answer:
about 1.14%
Step-by-step explanation:
Assuming you can redeem the T-bill for $100 at the end of the period, the interest rate can be found from the formula for simple interest:
I = Prt . . . . where P is the principal invested, r is the annual rate, and t is the number of years.
__
Here, we have ...
(100 -99.44) = 99.44·r·(180/365) . . . . held for a fraction of a year
0.56×365/(99.44×180) = r ≈ 0.0114195 ≈ 1.14% . . . . divide by the coefficient of r
Your return would be about 1.14%.
Answer:
Step-by-step explanation:
There is more than 1 way to do this problem, but all of them involve proportions. It's a good idea to learn how a proportion works: it's one of the key tools of the sciences.
Let the height of the Cactus = x
Ratio Cactus = Ratio Gate.
x/15 = 3/5
Notice that both ratios are set up as height / shadow. If you do this all the time (keep the ratio the same), you will never make a mistake on proportions.
x/15 = 3/5 Cross Multiply
5x = 15 * 3 Combine.
5x = 45 Divide by 5
5x/5 = 45/5
x = 9
The height of the cactus has to be less than the length of its shadow, which it is.
1/2+1/4
find LCD
1/2 is equal to 2/4 so
2/4+1/4=3/4
28/20+15/20=43/20=1 13/20 (I think)
.......
I can't do the rest cuz I'm in a rush but keep finding the least common denominator
