Answer:
125
Explanation:
5^2 = 25
25 x 5 = 125
Let William be x years old.
Thomas = (4 + x) years
In five years,
William = (x + 5) years
Thomas = 4 + x + 5 = (9 + x) years
Given, in five years sum of their ages is 24.
x + 5 + 9 + x = 24
2x + 14 = 24
2x = 24 - 14
2x = 10
x =
![\frac{10}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B10%7D%7B2%7D%20)
x = 5
Hence, William is 5 years old and Thomas is 9 years old.
Answer:
It takes 0.145 hours
Step-by-step explanation:
Given:
Distance = 8 miles
Speed = 55 miles per hour
To Find:
Time taken = ?
Solution:
The time taken for an object to travel a particular distance with a average speed can be found by
![\text{Time Taken} = \frac{distance}{ speed}](https://tex.z-dn.net/?f=%5Ctext%7BTime%20Taken%7D%20%3D%20%5Cfrac%7Bdistance%7D%7B%20speed%7D)
Now Substituting the given values , we get
![\text{Time Taken} = \frac{8}{55}](https://tex.z-dn.net/?f=%5Ctext%7BTime%20Taken%7D%20%3D%20%5Cfrac%7B8%7D%7B55%7D)
![\text{Time Taken} = 0.145](https://tex.z-dn.net/?f=%5Ctext%7BTime%20Taken%7D%20%3D%200.145)
Time taken will be 0.145 hours
Given :
Devin is buying 2 concert tickets. The concert tickets have a regular price of $40 each.
Devin has a coupon that gives a 5% discount off of the regular price of the tickets. He will then pay a 10% purchasing fee on the discounted price of the tickets.
To Find :
Devin's total cost of the two tickets after the discount and the fee.
Solution :
Discount on price, D = 40×0.05 = $2 .
Price of product after discount, P = $( 40 - 2 ) = $38 .
Now, total price after adding purchasing fee is :
T = P + (P×0.10)
T = 38 + (38×0.10)
T = 38 + 3.8
T = $41.8
Therefore, Devin's total cost of the two tickets after the discount and the fee is $41.8 .
Hence, this is the required solution.
