Answer:
the answer is -product of P(A) and P(B) is not equal to P(A and B)
To find the missing dimension you will use the formula for finding the volume of a prism and solve for the missing dimension. In this case 2ft is how deep the pool is and you will solve for the width of the pool.
V = Bh, where B is the area of the base. In this case, use the area of a trapezoid formula.
286 = 1/2h(8 +13)2
<u>286</u> = <u>21h</u>
21 21
h = 13.6
The width of the wading pool is approximately 13.6 feet.

Step-by-step explanation:
we know that
If the triangular piece of sheet metal is a right triangle, then the side lengths must satisfy the Pythagorean Theorem
so
where
c is the hypotenuse (the greater side)
a and b are the legs of triangle
we have
substitute
----> is true
so
The side lengths satisfy the Pythagorean Theorem
therefore
The triangular piece of sheet metal is a right triangle
Answer:
9/20
Step-by-step explanation:
LCM of 5, 20, and 10 = 20
4/5
= 4/5 x 4/4
= ( 4 x 4 )/( 5 x 4 )
= 16/20
2/10
= ( 2/10 ) x ( 2/2 )
= ( 2 x 2 )/( 10 x 2 )
= 4/20
4/5 - 3/20 - 2/10
= 16/20 - 3/20 - 4/20
= ( 16 - 3 - 4 )/20
= ( 16 - 7 )/20
= 9/20
