A machine can manufacture 24,000 plastic balls in 8 hours. Find the unit rate in balls per hour.

Final answer:

To determine how long one couple dances together, divide the total song duration by the number of times partners change plus one. With nine partner changes during a five-minute long song, each couple dances together for 0.5 minutes.

Explanation:

The question involves calculating the amount of time one couple dances together during a wedding dance if couples change partners nine times during a five-minute song. To find the answer, we need to divide the total time of the song by the number of times the partners change.

First, we find out how many times the couples will dance together. If they switch partners nine times, there will be ten different dancing intervals. Next, we divide the total length of the song by the number of intervals:

5 minutes ÷ 10 intervals = 0.5 minutes per interval.

Therefore, one couple dances together for 0.5 of a minute.

The volume of the box as a function of x will be 1400x - 180x² - 4x³.

First and foremost, you should note that the volume of a rectangular prism is given as:

= Length × Width × Height

where,

Length = 70 - 2x

Width = 20 - 2x

Height = x

Volume = Length × Width × Height

Volume = (x)(20 - 2x)(70 - 2x)

Volume = 1400x - 40x² - 140x² + 4x³

Volume = 1400x - 180x² - 4x³

Therefore, the volume of the box as a function of x will be 1400x - 180x² - 4x³.

If Joe bought 20 ounces of nuts at the store then the nuts in pounds is  1. 25 lb

What is Unit of Measurement?

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.

Joe bought 20 ounces of nuts at the store.

We have to find in pounds.

As we know that 1 ounce is equal to 0.0625 pounds.

Now we have to convert 20 ounces to pounds.

To do this we have to multiply 20 with 0.0625

20×0.0625

1.25 pounds

20 oz is equal to 1. 25 lb

Hence, the nuts in pounds is  1. 25 lb if Joe bought 20 ounces of nuts at the store.

Answer:

The answer is 4.25 cm.

Step-by-step explanation:

Given is - Joelle wants to place a figure which is 13.09 cm wide so that it appears centered on the page. The width of the page is 21.59 cm.

To solve, this first we will 13.09 from the 21.59, and then divide that number in half to find the left and right margin.  

[tex]21.59-13.09=8.5[/tex]

[tex]\frac{8.5}{2}= 4.25[/tex]

Therefore, the answer is 4.25 cm.

Answer:28.071

Step-by-step explanation:

Given

vector component is (15,8)

i.e. its x component is 15 from origin and y component is 8 m

So angle made by vector with x axis is

[tex]tan\theta =\frac{8}{15}[/tex]

[tex] \theta =tan^{-1}\frac{8}{15} [/tex]

we  know that

[tex]larger\ volume=original\ volume*(scale\ factor)^{3}[/tex]

and

[tex]larger\ surface\ area=original\ surface\ area*(scale\ factor)^{2}[/tex]

so

Find the scale factor

we know that

[tex](scale\ factor)^{3}=8 \\ scale\ factor=\sqrt[3]{8}=2[/tex]

Find the factor of the surface area increased

[tex](scale\ factor)^{2}=2^{2} =4[/tex]

therefore

the answer is

the surface area increased by a factor of [tex]4[/tex]

The need to cut the plastic by finding the measures of the angles (scale factor) is 4.

We have given,

Marcel is designing a circular necklace that will consist of 4 sections, each with a different color of plastic.

We  know that

larger volume=original volume×(scaler factor )^3

larger surface area =original surface area× (scaler factor)^2

To find the scale factor

we know that

(scalar factor)^3=8

Taking cube root on both sides

scale factor=2

Find the factor of the surface area increased

(scale factor)^2=2^2=4

Therefore, The surface area increased by a factor of 4.

The number 18 is considered an even number because it can be divided by 2 to result in another integer. This is confirmed by writing 18 as 2 times 9, which results in an even product.

In mathematics, an even number is any integer that can be exactly divided by 2 without leaving a remainder. For example, the numbers 2, 4, 6, 8, and 10 are even because each can be divided by 2 to result in another integer. If you divide an even number by 2, the result is always a whole number, and that's not the case with odd numbers. Let us examine the number 18.

If we write 18 as 2 times 9, we see that it has been turned into a product of 2 and another integer (9, in this case). This indicates that 18 is indeed an even number. Therefore, we can be sure of the fact that the number 18 is an even number, because it can be divided by 2 without leaving a remainder.

The tank can be rented for maximum of 6 hours.

We have school PTA wants to rent a dunking tank for its annual fundraising carnival. The cost is $80 for the first three hours and then $19.75 for each additional hour or part thereof.

We have to determine how long can the tank be rented if up to $200 is budgeted for this expense.

Initial count = 500

Count increasing per second = 5

Critical level = 1000

Assume that the bacteria count after t seconds is y. Then -

y = 500 + 5t

for t = 30 ↔ y = 150 + 500 = 650 < 1000 → Critical level not passed.

According to question, we have -

Cost for first three hours = $80

Cost for additional hour = $19.75

Total Budget = $200

Assume that the tank can be bought for 'n' hours. Then -

80 + 19.75n ≤ 200

Solving the inequality -

19.75n + 80 - 80 ≤ 200 - 80

19.75n ≤ 120

n ≤ 6.07

or

n ≤ 6

Hence, the tank can be rented for maximum of 6 hours.
