A sports company wants to package a ball with a 1.5-inch radius in sets of two. They have two options: a cylinder or a square pr

ism.
The company wants to use the package that has the least amount of wasted space. The company should choose

a.)the prism because it has approximately 11.6 in.3 less wasted space than the cylinder.
b.)the prism because it has approximately 14.1 in.3 less wasted space than the cylinder.
c.)the cylinder because it has approximately 11.6 in.3 less wasted space than the prism.
d.)the cylinder because it has approximately 14.1 in.3 less wasted space than the prism.

Answer:

C. the cylinder because it has approximately 11.6 in.3 less wasted space than the prism.

Step-by-step explanation:

if you find the volumes of both shapes and subtract the volumes of the two balls and then subtract the two remaining values you get a difference of 11.6 inches. This makes the cylinder smaller and therefore uses less space.

Answer:

Option c.) the cylinder because it has approximately 11.6 in.3 less wasted space than the prism.

Step-by-step explanation:

step 1

Find the volume of one ball

The volume of the sphere is equal to

V=\frac{4}{3}\pi r^{3}

we have

r=1.5\ in

V=\frac{4}{3}(3.14)(1.5)^{3}=14.13\ in^{3}

therefore

The volume of two balls is

(2)*14.13=28.26\ in^{3}

step 2

Find the volume of the cylinder

The volume of the cylinder is equal to

V=\pi r^{2}h

we have

r=1.5\ in

h=1.5*4=6\ in

substitute

V=(3.14)(1.5)^{2}(6)=42.39\ in^{3}

therefore

The wasted space with the cylinder is equal to

42.39\ in^{3}-28.26\ in^{3}=14.13\ in^{3}

step 3

Find the volume of the square prism

The volume of the square prism is equal to

V=b^{2}h

we have

b=1.5*2=3\ in

h=1.5*4=6\ in

substitute

V=(3)^{2}(6)=54\ in^{3}

therefore

The wasted space with the prism is equal to

54\ in^{3}-28.26\ in^{3}=25.74\ in^{3}

step 4

Find the difference of the wasted space

25.74\ in^{3}-14.13\ in^{3}=11.61\ in^{3}

Find the 100th term in the arithmetic sequence 0,5,10,15
Viktor [21]

Answer:

easy peasy,

the 'n' th term of any arithmetic sequence can be found with the following formula

=> a + ( n-1) d, [where 'a' if the first term of the sequence, 'n' the number of term we need to find, and 'd' being the common difference between each two consecutive term of the sequence)

all in this case would be,

a = 0

n = 100

d = +5

hence the 100th term would be,

=>  0 + (100 - 1) 5

=> 99 x 5

=> 495

T(z)= sin^2(z/4), {-3 ≤ z ≤ 8}
Usimov [2.4K]

Answer:

T´(z)=n^2s/4*i

Step-by-step explanation:

T(z)=d/dz(sin^2*z/4)

T´(z)=d/dz(sn^2zi/4)

T´(z)=d/dz(sn^2z/4*i)

T´(z)i*d/dz(sn^2z/4)

T´(z)=n^2s/4*i

Simplify

Find a rational number halfway in between the two numbers. three sevenths and one tenth
strojnjashka [21]
Answer:
The rational number is : 37/140

Explanation:
The first number given is three sevenths which can be written as 3/7
The second number given is one tenth which can be written as 1/10

Now, we want to get the midpoint between these two numbers. The midpoint can be calculated as follows:
midpoint = (first number + second number) / 2
midpoint = [(3/7) + (1/10)] / 2 
midpoint = 37/140

Hope this helps :)
