Answer:
x = 2.8 hours
Explanation
Total distance = 350 km
Time period = 3 hrs
Hence we need to formulate an equation...,
Distance = Speed × Time
; Distance covered travelling at 120 = 120x Since the total time period was 3hrs...then the remaining time is (3 - x)
;Distance covered travelling at 60 = 60(3- x)
The equation is going to be...,
; 120x + 60(3 - x) = 350...since total distance is 350 km
; 120x + 180 - 60x = 350
; 60x = 170....divide both sides by 60
Hence..., x = 2.8 hours
If you break up how many 300 go into 1050 it is about 3 1/2 laps so you just keep adding on untill they are both at numbers where both can meet so the faster runner would run about 3 1/2 more laps when they were both to meet at the starting line
1: 78.5
2: 7,850
1: we know the radius is 5, so we put it in the expression, making 3.14x5 to the second power, which makes 25 ( because 5x5) so 3.14x25=78.5
so our area is 78.5m
2:our radius is 50, so when we put it in the expression 3.14x50 to the second power we get 2500, so agian we do 3.14x2500=7850
so our area is 7850mm
Answer:
Step-by-step explanation:
<u> You did not provide the dimensions of the living room, so I will give you a general explanation of the procedure you need to apply to solve the exercise:</u>
According to the information provided in the exercise, the living room is a rectangle with a semi-circular alcove, then, you can conclude that its area can be obtained by adding the area of the rectangle and the semi-circle.
The area of a rectangle can be calculated with the following formula:
Where "l" is the length of the rectangle and "w" is the width.
The area of a circle can be calculated with this formula:
Where "r" is the radius of the circle.
Therefore the following formula can be used to find the area of a semi-circle:
Where "r" is the radius.
Then, the area of the living room is:
