Answer:
The value of the land after five years is $23,302.50.
Step-by-step explanation:
First you need to find 3.9% of $19,500 which is $760.5.
Then, you multiply 760.5 by 5 years and you get 3,802.5.
Lastly, you add 3,802.5 to 19,500 and get a total of $23,302.50.
Answer:
117 students, 8 adults
Step-by-step explanation:
Let's say a adults went and s students went.
Total cost for adults = 23 for each a = 23a
Total cost for each student = 16s
Number of adults and students = a + s = 125
Total cost = 23a + 16s = 2056
a + s = 125
23a + 16s = 2056
We can solve this by solving for a and then plugging that into the other equation, making it so that there is only one variable
subtract s from both sides in the first equation
a = 125 - s
plug that into the second equation
23(125 - s) + 16s = 2056
2875 - 23s + 16s = 2056
2875 - 7s = 2056
subtract 2875 from both sides to isolate s and its coefficient
-7s = -819
divide both sides by -7 to isolate s
s = 117
a = 125 - s = 125 - 117 = 8
Answer: x⁴y²⁰
Step-by-step explanation: Distribute the exponent ⁴ over the parentheses
(x y⁴)⁴ becomes x⁴y¹⁶ (multiply exponents)
then take the 4th root of y¹⁶ (divide the exponent of the radicand by the index) ⁴√y¹⁶ becomes y⁴
Then multiply the factors. Add exponents
x⁴y¹⁶ * y⁴ becomes x⁴y²⁰
Answer to a is 25 km. Reason is that 75/60= 1.25 , therefore going 1.25 km a min. Now myltiply that by 20 and you get 25 km in 20 minutes. Answer to b should be roughly 3 hours and 33 minutes. The reason is that 250 km / 75km/ hour = 3 hours 33 min.
Hope this helps
