Answer:
$5561.58
Step-by-step explanation:
The appropriate compound interest formula is ...
... A = P(1 +r/n)^(nt) . . . . . where P is the principal, r is the annual rate, n = the number of compoundings per year, t = the number of years
Filling in the given information, you have
... A = $4000×(1 +.03/12)^(12×11)
... = $4000×(1.0025^132)
... ≈ $5561.58

Look at the description of the formula in your list of formulas to find the right one. Plug in the numbers and do the arithmetic. If you can't run your calculator, you can type the expression into a Google search box.
Answer:
speed of train A = 70 + 20 = 90 miles per hour
speed of train B = 70 miles per hour
Step-by-step explanation:
Let
speed of train B = a
speed of train A = a + 20
Recall
speed = distance/time
The travel time is same for both train. Therefore, let us make time subject of the formula in the speed equation.
Time = distance/speed
270/a + 20 = 210/a
cross multiply
270a = 210(a + 20)
270a = 210a + 4200
270a - 210a = 4200
60a = 4200
divide both sides by 60
a = 4200/60
a = 70
speed of train A = 70 + 20 = 90 miles per hour
speed of train B = 70 miles per hour
Answer:
0
Step-by-step explanation:
Zero is a rational number, and we know that the integer 0 can be written in any one of the following forms. ... Thus, 0 can be written as, where a/b = 0, where a = 0 and b is any non-zero integer. Hence, 0 is a rational number and not an integer.
Answer:
In B, One card is chosen from a standard deck, it is set aside, then a second card is drawn. That "set aside" is where we have a problem. We began with 52 cards, but now have 51. This fact WILL change the probability or probabilities. Chances of obtaining a red heart from the full 52-card deck are 4/52; whereas chances of obtaining a red heart from the remaining 51 cards (assuming that you got a red heart earlier and set it aside) is 3/51.
Answer:
The sum of the two leg measures equals the hypotenuse.
Step-by-step explanation:
The answer choice "The measure of the hypotenuse squared is equal to the sum of the side measures squared" is true because it is the Pythagorean Theorem.
The other two answer choices basically describe what a hypotenuse is.
