Haley makes earrings and packages them into cube boxes that measure 1/6 foot wide. How many 1/6 foot cubic boxes can she fit int

alexandr402 [8]

Answer: 28 cube boxes.

Step-by-step explanation:

The volume of a cube can be found with this formula:

$V_{(c)}=s^3$

Where "s" is the lenght of any edge of the cube.

You need to find the volume of a cube box:

$V_1=s^3=(\frac{1}{6}ft)^3=\frac{1}{216}ft^3$

To find the volume of the shipping box, first we must convert the mixed number to an improper fraction. To do it, multiply the whole number part by the denominator of the fraction and add this product to the numerator.

The denominator does not change.

Then:

$1\ \frac{1}{6}=\frac{(1*6)+1}{6}=\frac{7}{6}$

Knowing the dimensions of the shipping box, you can calculate its volume by multiplying its dimensions. Then, this is:

$V_2=(\frac{7}{6}\ ft)(\frac{1}{3}\ ft)(\frac{1}{3}\ ft)=\frac{7}{54}\ ft^3$

Finally, in order to find the number of cube boxes can Haley fits into a shipping box, you must divide the the volume of the shipping box by the volume of one cube:

$\frac{\frac{7}{54}ft^3}{\frac{1}{216}ft^3}=28$

Help needed ASAP will give brainliest AND 5 STARS RATE

STALIN [3.7K]

Answer:

A or the first answer is correct

Step-by-step explanation:

3650 - 2000 = 1650

1650 / (divided by) 150 = 11

you can also check your work by doing 150 *(times) 11 = 1650

1650 + 2000 = 3650

Determine the values of n

N76 [4]

<h2>Answer:</h2><h3>b. n is odd</h3><h2>Step-by-step explanation:</h2>

In this problem, we assume that $n$ is a whole number. The definition of inverse functions tells us that a function $f$ has an inverse function if and only if the function is one-to-one, that is, if there is no any horizontal line intersecting the graph of $f$ at more than one point. This only happens if $n$ is odd. This is called the Horizontal Line Test for Inverse Functions. So let's take two examples:

FIRST:

$n=2 \\ \\ f(x)=x^2$

Since n is even, an horizontal line will pass through two points as indicated in the first figure below.

SECOND:

$n=3 \\ \\ f(x)=x^3$

Since n is odd, an horizontal line will pass through just one point as indicated in the second figure below.

PLEASE HELP!!! WILL GIVE BRAINLEST AWARD FOR MOST DESCRIPTIVE

Rashid [163]

The law of cosines states that:

c^2=a^2+b^2-2abcosC

You already have all the values for the variables with the exception of x so:

x^2=25+100-100cos60

x=√(125-100cos60)

x=√75

x≈8.66 to nearest one-hundredth...

On a field trip, there are 5 adult chaperones for every group of 20 students. There are 150 people in total on the trip. What pe

denis23 [38]

Answer:

80% of the people on the trip are children.

Step-by-step explanation:

To determine the percentage of the people on the trip that are children,

First, we will determine how many of the people are children.

From the question,

There are 5 adult chaperones for every group of 20 students, that is, out of 25 people, 5 are adult chaperones and 20 are students.

From the question, there are 150 people in total in total.

Let the number of children be x

If there are 20 students (children) in 25 people

Then, there will be x children in 150 people

x = (150 × 20) / 25

x = 120

Hence, there are 120 children.

To determine the percentage of the people on the trip that are children,

we will divide the number of children by the total number of people and then multiply by 100%

Number of children = 120

Total number of people = 150

∴ The percentage of the people on the trip that are children is

(120/150) × 100% = 0.8 × 100% = 80%

Hence, 80% of the people on the trip are children.
