Answer:
5:21
Step-by-step explanation:
We know that currently (in the problem) it is 25 min before 4, or 3:35. When we add an hour to that (first part of the problem), we get 4:35. The way l like to continue from here is to take the second part (the 46 min) and just use part of it to round the hour off, and then add the other part to it.
From 4:35 to 5, we have 25 min
4.35 + 25 = 5
We subtract those 25 min from the 46 min, since we used them to round the hour off.
46 - 25 = 21
We have 21 min left, and now that the hour is rounded off, it's way easier to add minutes to it.
5 + .21 = 5.21.
So an hour and 46 min from 3:35 it will be 5:21. I hope this helps :)
Answer:
New cars sold = 20,
Used cars sold = 25
Cars serviced = 290
Step-by-step explanation:
In a month they sold fifteen less used cars than twice the number of new cars.
Lets say 'x' number of new cars were sold, then:
The number of used car sold is:
In the same month they serviced fifty more than twelve times the number of new cars sold. So the number of cars serviced is:
Altogether they sold or serviced 335 cars, so the sum of all the cars sold and serviced should be 335:
Solving for 'x' we get:
Therefore, the number of new cars sold in that month is 20.
Number of used car sold 
Number of cars serviced 
We can also cross check by summing them up:
Answer:
No, The answer should be 240
Step-by-step explanation:
- The first step to finding the Surface Area was done well and was right but you got confused when trying to add the area of each shape
- There is 3 Rectangles and 2 Traingles.
- Let's start with the area of the triangles. 1/2bh is the formula for finding area of Traingles. 1/2(4)(6) = 12. We have two Traingles so that would be 24.
- Now we have three rectangles with different lengths we need to calculate.
- Rectangle 1 = 12 * 8 = 96
- Rectangle 2 = 12 * 6 = 72
- Rectangle 3 = 12* 4 = 48
- 24+96+72+48 = 240.
- So, the surface area of the rectangular prisim is 240
