Answer:
<em>2,143.6in³</em>
Step-by-step explanation:
The beach ball is spherical in nature;
Volume of the ball = 4/3πr³ where;
r is the radius of the ball = 8in
Substitute into the formula;
Volume of the ball = 4/3π(8)³
Volume of the ball = 4/3π(512)
Volume of the ball = 2,048(3.14)/3
Volume of the ball = 2,143.57in³
<em>hence the volume of the ball is 2,143.6in³</em>
Answer:
1 hour = 1.7 miles / 1.5 hours = ? Miles
1.7 × 0.5 = 0.85 + 1.7 = 2.55 Miles
Step-by-step explanation:
1.7 × 0.5 = 0.85 + 1.7 = 2.55 Miles
Since the expected value for this game is negative, Armando will lose money.
- The expected value is given by the <u>sum of all outcomes multiplied by it's respective probability.</u>
In this problem:
- There are blue, yellow, white, red and green marshmallows, each with a probability of being picked.
- If red or green marshmallows are picked, Armando get the charge of $0.1.
- If someone picks a blue marshmallow, he loses $0.1.
- If someone picks a yellow marshmallow, he loses $0.4.
- If someone picks a white marshmallow, he loses $0.9.
Thus, the expected value is:
Since the expected value for this game is negative, Armando will lose money.

Answer:
Step-by-step explanation:
Initial length of the cardboard was y cm, and width was x cm.
The new dimensions are:
length = (y - 25) cm
width = (x - 15) cm
Area of the new rectangle = length x width
= (y - 25) x (x - 15)
= (y - 25) (x - 15)
Perimeter = 2 ( length + width)
= 2 ((y - 25) + (x - 15))
= 2(y - 25) + 2(x - 15)
Therefore:
2(x + y) - 40 is neither of these
2(x - 15) + 2(y - 25) is the perimeter
(x - 15)(y - 25) is the area
(x - 25)(y - 15) is neither of these
2(x - 15)(y - 25) is neither of these
2x + 2y - 80 is the perimeter
xy - 375 is neither of these
x + y - 40 is neither of these
