Answer:
249.6
Step-by-step explanation
There are 4 identical equilateral triangle,
we can find the area of one and multiply by 4
area of triangle =
now 62.4*4 = 249.6
The probability of a coin landing on heads is a 50 percent chance. Because there are only two sides. So there is a 1 out of 2 chance it will land on heads. And 1/2 is equal to 50 percent.
Answer:
On a coordinate plane, a point is 3 units to the left and 5 units up. Another point is 4units to the right and 3 units down
Step-by-step explanation:
The coordinate plane is a plane formed from the intersection of the x axis (horizontal line) and y axis (vertical line). The point of intersection of these axis is known as the origin. A point can be represented on the coordinate plane using the x and y coordinates.
The x axis is to the left and right of the origin, negative points are to the left of the origin while positive points are to the right of the origin. The y axis is to the up and down of the origin, negative points are to the down of the origin while positive points are to the up of the origin.
A point in the coordinate plane is represented as (x, y).
The location of point (-3,5) is 3 units to the left and 5 units up while point (4, -3) is 4units to the right and 3 units down
Answer:
The rate at which both of them are moving apart is 4.9761 ft/sec.
Step-by-step explanation:
Given:
Rate at which the woman is walking, = 3 ft/sec
Rate at which the man is walking, = 2 ft/sec
Collective rate of both, = 5 ft/sec
Woman starts walking after 5 mins so we have to consider total time traveled by man as (5+15) min = 20 min
Now,
Distance traveled by man and woman are and ft respectively.
⇒
⇒
As we see in the diagram (attachment) that it forms a right angled triangle and we have to calculate .
Lets calculate h.
Applying Pythagoras formula.
⇒
⇒
Now differentiating the Pythagoras formula we can calculate the rate at which both of them are moving apart.
Differentiating with respect to time.
⇒
⇒
⇒ ...as
⇒ Plugging the values.
⇒ ...as ft/sec
⇒ ft/sec
So the rate from which man and woman moving apart is 4.9761 ft/sec.
