Answer: 168 child tickets were sold.
Step-by-step explanation:
Given: The ratio of child to teen to adult tickets sold at a water park on Saturday was 4:1:2.
Let the number of child tickets = 4x , teen tickets = x , adult tickets = 2x
Total tickets = x+4x+2x = 7x =294
![\Rightarrow\ x=\dfrac{294}{7}\\\\\Rightarrow\ x=42](https://tex.z-dn.net/?f=%5CRightarrow%5C%20x%3D%5Cdfrac%7B294%7D%7B7%7D%5C%5C%5C%5C%5CRightarrow%5C%20x%3D42)
Number of child tickets = 4(42) = 168
Hence, 168 child tickets were sold.
Answer:
21 is the answer
Step-by-step explanation:
The modulus ar absolute symbol...the two straight lines does not take into consideration the positive or negative signs and the answer always remains positive with the same numbers like in this case it is 21.
Answer: The slope is 12 pounds per day.
Step-by-step explanation:
They consumed 60 pounds on food in 5 days.
The slope or rate at which they consummed the in a day can be calculated as the amount of pounds consumed in the lapse of time, this is:
slope = 60pounds/5days = 12 pounds per day.
Answer:
B
Step-by-step explanation:
The compound interest formula is
where:
- P is the starting amount called the principle
- r is the rat written as a decimal
- n is the number of times compounded in a year
- t is the number of years
Substitute a value into each variable to solve.
- P = $147 since 10% of 1,470 is being invested which makes P = 0.10(1470) = 147.
- The rate is 3.5% or r = 0.035.
- n = 12 because it is compounded monthly meaning 12 times a year.
- t = 25 since it will earn for 25 years.
![A = P (1+r/n)^{nt}\\A = 147(1 + \frac{0.035}{12})^{12*25}\\A = 147 ( 1 + 0.002916)^{300}\\A = 147(1.002916)^{300}\\A = 352.19](https://tex.z-dn.net/?f=A%20%3D%20P%20%281%2Br%2Fn%29%5E%7Bnt%7D%5C%5CA%20%3D%20147%281%20%2B%20%5Cfrac%7B0.035%7D%7B12%7D%29%5E%7B12%2A25%7D%5C%5CA%20%3D%20147%20%28%201%20%2B%200.002916%29%5E%7B300%7D%5C%5CA%20%3D%20147%281.002916%29%5E%7B300%7D%5C%5CA%20%3D%20352.19)
Repeat this process for each formula.
