- Rounding 789 nearest to tens will be 790.
Step-step Explanation:
Let's know how to round any number nearest to tens (Rules):-
We know tens place in any no. from left is at second place and number right to tens place need to be changed as:-
- If last digit is 0, then we don't have to do any rounding, because it is already to the ten.
- We round the no. down to the nearest ten if the last digit in the no. is 1, 2, 3, or 4
- We round the no. up to the nearest ten if the last digit in the no. is 5, 6, 7, 8, or 9.
Answer:
55 inches.
Step-by-step explanation:
So, in the question above we are given the following data or parameters or information which will assist us in solving this kind of question efficiently. Here are the information needed below;
(1). "Television sizes are labeled by the measure of the diagonal.''
(2). "47.5 inches up top and the side is 27 inches" which are the length and the breadth respectively. Therefore, we will make use of the formula below In solving this question;
Size of the Television = √[(Length of the Television)^2 × (breadth of the television)^2].
Hence, the size of the Television = √( 47.5)^2 + (27)^2. = 54.63744137494.
Approximately:
The Size of the Television = 55 inches.
Okay, so my last answer was deleted because I didnt show any work.
According to the rule,
a+b>c
c+b>a
c+a>b
so...
2+3=6...6<7
21+23=44...44+44
12+36=48...48<53
14+17=31...31>30
Since answer D is the only answer that fullfills the rule a+b>c, it is the correct answer
Answer:
The car must move 48 km/h.
Step-by-Step Explanation
- Denote x km/h the speed of the car.
5*x km while the bus for 5 hours travel the distance:
5*30=150 km ,since the bus left 3 hours before the car its total distance from the car is 150+3*30=240 km. The car overtake the bus when 5*x=240 where x=48 km/h.
