5. A softball has a diameter of 8.3 in. How many softballs will fit inside of a storage unit 4 that is 15 feet wide, 10 feet lon

Westkost [7]

Answer:

4329 softballs

Step-by-step explanation:

To find the number of softballs that will fit into the container, we first find the volume of the softball. Since it is a sphere, its volume V = 4πr³/3 where r = radius = d/2 where d = diameter of softball.

So, V = 4π(d/2)³/3 = πd³/6

Since d = 8.3 in,

V = πd³/6 = π(8.3 in)³/6 = π × 571.787 in³/6 = 299.39 in³

The volume of the box, V' = 15 × 10 × 5 ft³ = 750 ft³ = 750 × (12 in)³ = 750 × 1,728 in³ = 1,296,000

So, for n softball to fit, its volume must equal the volume of the storage unit.

The volume of n softballs is nV.

For the softballs to fit, V' = nV

n = V'/V

= 1,296,000 in³/299.39 in³

= 4328.8 softballs

≅ 4329 softballs since we cannot have a decimal number of softballs.

The surface area of a rectangular prism is 198 cm2. Two of the dimensions are 3 cm and 9 cm. Find the measure of the other dimen

Alecsey [184]

In this question, it is given that two of the dimensions are 3 cm and 9 cm . Let the other dimension be x cm .

And the surface area of the rectangular prism is given. Now we use the formula of surface area of prism, which is

$A = 2(length* width + width * height + length * height )$

$198 = 2(3*9 + 3*x + 9*x)$

$99 = 27 + 12x$

Subtracting 27 to both sides,

$72 = 12x$

Dividing both sides by 12

$x = 6$

So the length of the remaining dimension is 6 cm .

Given: g(x) = 2x – 1 and h(x) = x2 - 2x + 8<br> 7. Find (g- h)(x)<br> Show work

Natali [406]

Answer: -x²+4x-9

Step-by-step explanation:

(g-h)(x) is the same as g(x)-h(x). Since we were given g(x) and h(x), we can subtrac them.

2x-1-(x²-2x+8) [distribute -1]

2x-1-x²+2x-8 [combine like terms]

-x²+4x-9

Now, we know thhat (g-h)(x)=-x²+4x-9.
