Your answer is 560cm^2.
We get this answer first by dividing 96 by 2, because the perimeter is made up of 2 lots of both sides. This gives us 48cm.
Then we find out how long each side is by adding together 5 and 7 to give us 12, and dividing 48 by 12 to give us 4. This is how big each of the 'parts' of the ratio are. Then, we just multiply 4 by 5 to get 20, and 4 by 7 to get 28.
This tells us that 20 and 28 are the side lengths, so we just need to multiply them together to get the area of the rectangle, which gives us 560cm^2.
I hope this helps! Let me know if you have any questions :)
Answer:
14^2/15
Step-by-step explanation:
70/15 simplifies to 14/3
14/3 X 14/5
= 14^2/15
A plane consists of an infinite set of points.
A point's location on the coordinate plane is indicated by an ordered pair, (x, y).
Step-by-step explanation:
The undefined terms in geometry are points, lines and planes.
- A point's location on the coordinate plane is indicated by an ordered pair, (x, y). TRUE. In R², the ordered pairs (x,y) is used to defined the location of a point.
- The second statement is false because a point has no dimension.
- The third statement is also false because a line has only one dimension which is length.
- The fourth statement is not true because distance between two points must have a beginning and an end.
- A plane consists of an infinite set of points. TRUE .The plane is a home of infinitely many points.
Answer:
A- Using real world problems to help students learn to solve them on their own
Explanation:
"Problem-based learning" is a teaching approach that centers on students. It allows the student to learn on their own or to solve problems on their own. This is also based on their own <em>"reasoning"</em> and <em>"reflection." </em> So, the role of the teacher here is to facilitate or guide the students. He doesn't need to provide direct instruction to the student. The goal here is "self-identified," so this means that the <u>students identity their own goals.</u> Real word problems are used in order for the students to learn how to solve them on their own.
So, this explains the answer.
Recall your d = rt. distance = rate * time.
let's say the speed of the current is "c".
keeping in mind that, when the boat is going against the current, the boat is not really going at 2kmh, but instead at " 20 - c ", because the current is subtracting speed from it.
Likewise when is going with the current, is going at a speed of " 20 + c ".
if the boat took say "t" hours on the way over, on the way back it took the slack from the whole 8 hours and "t", namely it took " 8 - t " hours.
