In English language, a sentence is a group of words or phrases that comprises a subject and predicate, which are typically used by an author or speaker in order to convey a logical information about a subject matter to an audience (readers or listeners).

A verb is one of the parts of speech in English language and it refers to any word that describes an action, occurrence, or a state of existence.

In this context, we can reasonably infer and logically deduce that the most appropriate word to complete the sentence is "are" because it is a linking verb and it connects the subject with objects in plural form.

Answer:

[tex]V=\frac{49}{2}\ cm^3[/tex]

or

[tex]V=24.5\ cm^3[/tex]

Step-by-step explanation:

we know that

The volume of the rectangular prism is

[tex]V=LWH[/tex]

where

L is the length

W is the width

H is the height

substitute the given values in the formula

[tex]V=(\frac{7}{5})(5)(\frac{7}{2})[/tex]

[tex]V=\frac{245}{10}\ cm^3[/tex]

Simplify

[tex]V=\frac{49}{2}\ cm^3[/tex] ---> fraction form

or

[tex]V=24.5\ cm^3[/tex] ----> decimal form

The volume of the rectangular prism is 24.5 cm³.

To find the volume of a rectangular prism, you use the formula Volume = length × width × height. Given the dimensions of the prism are 7/5 cm by 5 cm and 7/2 cm, we calculate the volume by multiplying these three dimensions together.

Volume = (7/5) cm × 5 cm × (7/2) cm

First, simplify the calculation by multiplying the whole numbers: Volume = (7 × 5 × 7) / (5 × 2) cm³, which simplifies to Volume = 49/2 cm³. Then, divide 49 by 2 to get Volume = 24.5 cm³.

Complete Question:

As you missed to add the area and length value. So, after a little research I was able to find the complete question. I will answer the question based on this complete question I am mentioning, but hopefully it would clear your concept anyways. So, here is the complete question.

The Area of a rectangular patio is 5 5/8 square yards, and it's length is 1 1/2 yards.What is the patio's width,in yards?

Answer:

The width of patios is [tex]w = \frac{15}{4} yards[/tex].

Step-by-step explanation:

As the area of a rectangular patio is [tex]A = 5\frac{5}{8}[/tex] square yards.

⇒ [tex]A = 5\frac{5}{8}[/tex]

⇒ [tex]A = 5\frac{5}{8}[/tex] can be written as : [tex]A = \frac{45}{8}[/tex]

The length of a rectangular patio is [tex]l = 1\frac{1}{2}[/tex] square yards.

⇒[tex]l = 1\frac{1}{2}[/tex]

⇒[tex]l = 1\frac{1}{2}[/tex]  can be written as : [tex]l = \frac{3}{2}[/tex]

As the area of rectangular patio can be computed by multiplying the length and width. So, width [tex](w)[/tex] can be computed by dividing the Area by length.

[tex]A = lw[/tex]

[tex]w = \frac{A}{l}[/tex]

So, [tex]w = \frac{\frac{45}{8}}{\frac{3}{2} }[/tex]

[tex]w = (\frac{45}{8}) (\frac{2}{3} )[/tex]

[tex]w = \frac{90}{24}[/tex]

[tex]w = \frac{15}{4}[/tex] or [tex]w = 3\frac{3}{4}[/tex]

Hence, the width of patios is [tex]w = \frac{15}{4} yards[/tex].

Step-by-step explanation:

To find out what fraction of 2 1/2 is 4/5, convert 2 1/2 to a fraction (5/2), then multiply 4/5 by the reciprocal of 5/2 which gives 8/25. So, 4/5 is 8/25 of 2 1/2.

The question is asking about what fraction of 2 1/2 is 4/5. In order to solve this, we should firstly convert the mixed number 2 1/2 to a fraction, which is 5/2. Then we have to divide 4/5 by 5/2 to find out the fraction. To divide fractions, we multiply the first fraction (the dividend) by the reciprocal of the second fraction (the divisor).

So, the problem becomes 4/5 * 2/5, and the solution is 8/25. Therefore, 4/5 is 8/25 of 2 1/2.

Answer:

D

Step-by-step explanation:

You can see, MN consists of the three lines in the picture. So you just need to sum them tougher in an equation with it's original value 81.

5 + 3x - 8 + 4x = 81

7x = 81 + 3

7x = 84 / : 7

x = 12

The value x from the given line segment is 12 units. Therefore, option D is the correct answer.

A line segment is a path between two points that can be measured. Since line segments have a defined length, they can form the sides of any polygon.

Given that, MN=81.

Here, MN=5+3x-8+4x

MN=7x-3

7x-3=81

7x=81+3

7x=84

Answer:

The closed linear form of the given sequence is [tex]a_{n}=0.75n-0.45[/tex]

Step-by-step explanation:

Given that the first term [tex]a_{1}=0.3[/tex] and [tex]a_{n+1}=a_{n}+0.75[/tex]

To find the closed linear form for the given sequence

The formula for arithmetic sequence is

[tex]a_{n}=a_{1}+(n - 1)d[/tex]  (where d is the common difference)

The above equation is of the given form  [tex]a_{n+1}=a_{n}+0.75[/tex]

Comparing this we get d=0.75

With [tex]a_{1}=0.3[/tex] and d=0.75

We can substitute these values in [tex]a_{n}=a_{1}+(n - 1)d[/tex]

[tex]a_{n}=a_{1}+(n - 1)d[/tex]

[tex]=0.3+(n-1)(0.75)[/tex]

[tex]=0.3+0.75n-0.75[/tex]

[tex]=-0.45+0.75n[/tex]

Rewritting as below

[tex]=0.75n-0.45[/tex]

Answer:

The total payment Janie have to make is $5466 .

Step-by-step explanation:

Given as :

The loan principal = $4850

The rate of interest applied = 13.8% compounded monthly

Let The time period of loan = t years

The monthly payment she make = $455.50 each month

I.e She make payment for t years = $455.50 × n

where n is the number of terms

From Compound Interest

Amount = Principal × [tex](1+\dfrac{\textrm rate}{12\times 100})^{12\times time}[/tex]

Or,  $455.50 × n  = $4850 × [tex](1+\dfrac{\textrm 13.8}{12\times 100})^{12\times time}[/tex]

Or, [tex]\dfrac{455.50}{4850}[/tex] × n  = [tex](1.0115)^{12\times 1}[/tex]

Or, 0.0939 × n  = [tex](1.0115)^{12}[/tex]

Or, 0.0939 × n = 1.14707

∴ n = [tex]\dfrac{1.14707}{0.0939}[/tex]

I.e n = 12.21 ≈ 12

So, The number of terms Janie she will pay = 12

So, The total payment she have to make = $455.50 × 12 = $5466

Hence The total payment Janie have to make is $5466 . Answer

Let's note the information.

This is what we know:

Every buttons came in packages of 30 per student.

Every bookmark came in packages of 50 per person.

Know, we need to do some multiplying.

30 x 400 & 50 x 400

Now solve.

30 X 400 = 12000.

So we now know that they have an estimated 12000 buttons total.

Now, we find x for bookmarks.

50 x 400 = 20000

That means total that estimated that 20000 bookmarks will be given.

Answer:

15 packages of buttons

9 packages of bookmarks

Step-by-step explanation:

We need to find the least common multiple (LCM) of 30 and 50.

30 = 2×3×5

50 = 2×5²

LCM = 2×3×5²

LCM = 150

Now we need to find a multiple of LCM that is greater than 400.

3LCM = 450

The committee needs at least 450 of each, which means they need at least 15 packages of buttons and 9 packages of bookmarks.

x = - 9, x = 0, x = 7

Step-by-step explanation:

Given

[tex]\frac{1}{2}[/tex] x(x - 7)(x + 9) = 0 ← in standard form

Equate each factor to zero and solve for x

[tex]\frac{1}{2}[/tex] x = 0 ⇒ x = 0

x - 7 = 0 ⇒ x = 7

x + 9 = 0 ⇒ x = - 9

Answer:

-9, 0, 7

Step-by-step explanation:

Finding the roots of a polynomial equation is the same as solving the equation. So, simply figure out which values make the equation equal 0.

If multiplication is involved, then 0 is always an answer (or root). Because anything multiplied by 0 is always 0.

7 is also a root:

7 - 7 = 0

Same with -9:

-9 + 9 = 0

Answer:

t=2.08 seconds.

Step-by-step explanation:

Well, in this example, H(t)=-0.6cos(2pi/2.5)t+1.5 should be equal to 1.2. If calculated, -0.6cos(0.8pi)t=1.2-1.5 which is equal to -0.6cos(0.8pi)t=-0.3, then cos(0.8pi)t=0.5. The value of cosine in terms of radians when it is equal to 0.5 is pi/3. So, cos(0.8pi)t=cos(pi/3). If simplified, (0.8pi)*t=5pi/3. pi's are cancelled out and t is calculated as 2.08333... If rounded to the nearest hundredth it is 2.08.

the answer is 3

Step-by-step explanation:

Final answer:

The multiplication property of equality states that multiplying or dividing both sides of an equation by the same number does not change the equality. The reciprocal of 1/3 is 3/1 or 3. So, if you multiply or divide both sides of an equation by 3/1 (the reciprocal of 1/3), you will maintain the equality.

Explanation:

The multiplication property of equality states that multiplying or dividing both sides of an equation by the same number does not change the equality. In this case, we have the fraction 1/3. The reciprocal of 1/3 is 3/1 or 3. Multiplying both sides of an equation by 3 is equivalent to dividing both sides by 1/3. So, if you multiply or divide both sides by 3/1 (the reciprocal of 1/3), you will maintain the equality.

Answer: 23.548

Step-by-step explanation: The thousandths place is 3 places to the right of the decimal point so in this problem, the digit in the rounding place is 8.

The rules of rounding says that if the digit to the right of the rounding place is greater than or equal to 5, we round down but if the digit to the right of the rounding place is less than 5, we round down.

Since the digit to the right of the rounding place, 1, is less than 5, we round down. This means that the digit in the rounding place which is 8 stays the same and we change all digits to the right of 8 to zero.

So we have 23.5480.

Finally, it's important to understand that when rounding decimals, we can drop any zeroes to the right of the decimal point as long as they're also to the right of the rounding place.

This means that 23.5481 rounded to the nearest thousandth is 23.548.
