An 80 ounce bottle of apple juice contains 32 ounces of water a 64 ounce bottle of orange juice has 48 ounces of water which jui
satela [25.4K]

Answer:

Part 1) 40% of the 80 ounce bottle of apple juice is water

Part 2) 75% of the 64 ounce bottle of orange juice is water

Part 3) An 64 ounce bottle of orange juice has a greater percent of water

Step-by-step explanation:

Part 1) we know that

An 80 ounce bottle of apple juice contains 32 ounces of water

In this problem

80 ounce bottle of apple juice represent the 100%

so

using proportion

Find out how much percentage represent  32 ounces of water

Let

x ----> the percentage of ounces of water

\frac{80}{100}=\frac{32}{x} \\\\x=100(32)/80\\\\x=40\%

therefore

40% of the 80 ounce bottle of apple juice is water

Part 2) we know that

An 64 ounce bottle of orange juice contains 48 ounces of water

In this problem

64 ounce bottle of orange juice represent the 100%

so

using proportion

Find out how much percentage represent  48 ounces of water

Let

x ----> the percentage of ounces of water

\frac{64}{100}=\frac{48}{x} \\\\x=100(48)/64\\\\x=75\%

therefore

75% of the 64 ounce bottle of orange juice is water

Part 3) which juice has a greater percent of water?

Compare the percentage of ounces of water in both bottles

75\% > 40\%

therefore

An 64 ounce bottle of orange juice has a greater percent of water

Which of these triangle pairs can be mapped to each other using a single translation?
sergeinik [125]

Answer:- D shows the triangle pairs which can be mapped to each other using a single translation.


Explanation:-

Translation is a rigid transformation which creates a congruent image as that of the original figure such that the distance between the each point of the original figure and the image is fixed and same.

The translation mapping is given by (x,y)→(x+h,y+k) ,where h is the distance of the x coordinate of the each point of the original figure to the image and  k is the distance of the y coordinate of the each point of the original figure to the image.

In figure D we can see that the distance between each point of ΔCED is equal to the distance between each point of ΔMPN. Thus it shows  the triangle pairs which can be mapped to each other using a single translation.

A waste management company is designing a rectangular construction dumpster that will be twice as long as it is wide and must ho
photoshop1234 [79]

Answer:

The dimensions that minimize the surface are:

Wide: 1.65 yd

Long: 3.30 yd

Height: 2.20 yd

Step-by-step explanation:

We have a rectangular base, that its twice as long as it is wide.

It must hold 12 yd^3 of debris.

We have to minimize the surface area, subjet to the restriction of volume (12 yd^3).

The surface is equal to:

S=2(w*h+w*2w+2wh)=2(3wh+2w^2)

The volume restriction is:

V=w*2w*h=2w^2h=12\\\\h=\frac{6}{w^2}

If we replace h in the surface equation, we have:

S=2(3wh+2w^2)=6w(\frac{6}{w^2})+4w^2=36w^{-1}+4w^2

To optimize, we derive and equal to zero:

dS/dw=36(-1)w^{-2} + 8w=0\\\\36w^{-2}=8w\\\\w^3=36/8=4.5\\\\w=\sqrt[3]{4.5} =1.65

Then, the height h is:

h=6/w^2=6/(1.65^2)=6/2.7225=2.2

The dimensions that minimize the surface are:

Wide: 1.65 yd

Long: 3.30 yd

Height: 2.20 yd

What is the completely factored form of p4 - 16?
il63 [147K]

The completely factored form of p^4-16 is:

(p^2+4)(p+2)(p-2)

Step-by-step explanation:

We have to factorize the given expression to get the final result

Given

p^4-16\\Using\ Formula: a^2-b^2=(a+b)(a-b)\\(p^2)^2-(4)^2\\=(p^2+4)(p^2-4)

p^2-4 can further be factored again

=(p^2+4)[(p)^2-(2)^2]\\=(p^2+4)(p+2)(p-2)

The completely factored form of p^4-16 is:

(p^2+4)(p+2)(p-2)
