Answer:
84.85 feet or 60 feet.
Step-by-step explanation:
Given that:
Distance of paths between each pair of consecutive bases is 60 ft.
To find:
Distance that the ball needs to travel if it is thrown directly from home plate to second base?
Solution:
Actually the given problem can be mapped to a right angled triangle in which base and height are given to be equal to 60 ft (because each pair of consecutive bases are 60 ft apart), Plus, they are at right angles to each other.
So, kindly refer to the image attached.
AB and BC are the distance of paths between consecutive bases.
And we have to find AC.
We can use Pythagorean theorem to find out the Hypotenuse of the triangle.
According to Pythagorean theorem:
Hwy friend
Let's figure this out.
5+7+4+4= 20 total students
4/20 students have hazel eyes
6/20 students do not have hazel eyes
16 / 20 =.8
80% chance that 1 is not hazel
80% that the 2nd isn't hazel
To find the probability that both will not be hazel you must multiply:
80% by 80% (.8 * .8)
.8 *.8 = .64
There is a 64% chance both of the selected students wont have hazel eyes.
Answer:
let the numbers be
X , y and z
X+ y + z = 20
first number is 4 times the sum of other 2
X = 4(y+ z)
second is 7 times third
y = 7z
now substituting back
X= 4 (7z + z)
X= 32z
32z + 7z + z = 20
40z = 20
z = 1/2
y = 1/2 * 7 = 7/2
X = 1/2 * 32 = 32/2
1/2 * 7/2 * 16 = 28
28 is the answer!
Answer:
B.
Step-by-step explanation:
The given matrix is
The determinant of this matrix is
Since the determinant is not zero, it means the inverse exists.
The inverse is given by
The correct choice is B.
Answer:
8^ (1/3) =2
Step-by-step explanation:
We want to find cube root of 8
8^ (1/3)
What number times itself 3 times is 8
2*2*2 =8
8^ (1/3) =2
