Answer:
3 rows/hour
Step-by-step explanation:
It is given that, Jose takes 120 minutes to weed 6 equal rows of vegetable plants in his garden.
120 minutes = 2 hours
We need to find the unit rate per hour for weeding these rows of his garden. It can be calculated as follows :
So, the rate for weeding these rows of his garden is 3 rows per hour.
The value of x is
Explanation:
Since, from the figure we can see that, a ray bisects the angle of a triangle.
Then, the angle bisector theorem states that, "if a ray bisects an angle of a triangle, then it divides the opposite sides of the triangle into segments that are proportional to the other two sides".
Thus, we have,
where and
Substituting the values, we get,
Simplifying, we have,
Dividing both sides by 4,
Thus, the value of x is
Answer:
<em>Answer: B'(-5,2)</em>
Step-by-step explanation:
<u>Rotations</u>
When rotating a point B(x,y) 90 degrees counterclockwise about the origin it maps to an image point B'(-y,x).
The image shows a figure formed by points ABCD. The coordinates of B are B(2,5).
This point will be rotated 90 degrees counterclockwise about the origin, thus the coordinates of the image point B' are B'(-5,2).
Answer: B'(-5,2)
(0, -2) and (1, 0)
You can get these answers by setting the two equations equal to each other and solving. You'll get x = 1 and x = 0. Plug in for the y values.
