Answer:

The volume of a juice box is 18 cubic inches.

Step-by-step explanation:

Given the dimensions

Interpreting the dimensions such as:

Using the formula to determine the volume

[tex]V=\:l\:\times \:w\:\times \:h[/tex]

substitute l = 3, w = 3/2, h = 4

[tex]V=3\times \frac{3}{2}\times \:4[/tex]

[tex]V\:=\:\frac{36}{2}[/tex]

[tex]V = 18[/tex] cubic inches

Therefore, the volume of a juice box is 18 cubic inches.

Answer:  So  Reina and Sam are multiplying (84)5 (73)9 and their work are (84)5 (73)9 = 84 + 573 + 9 = 89712 Reina's (84)5 (73)9 = 84-573-9 = 820727

So Sam's Actually they are doing or multiplying using exponents. Reina's work (8*)s(7³)º=8*+5+ 73+9= 8° 712 This is incorrect because she added exponents instead of multiplying exponents Sams work (8*)5 (7³)º=84x5 73x9= 820 727 This is correct because Sam multiplied exponents correctly Exponents are multiplied not added.

Answer:

n = 17. This means, √(18 x 17 x 34) = √(10404) = 102.

Step-by-step explanation:

An integer is a number that is not a fraction.

Given √(18 x n x 34), for the expression to be an integer, the product must be a perfect square. We are looking for n, the smallest number to multiply 18 x 34 to make it a perfect square. We have:

18 x 34 = 2 x 9 x 2 x 17 = 2 x 3 x 3 x 2 x 17 = 2² x 3² x 17.

From here, we see that we need to multiply an extra 17 to make it a perfect square, therefore n = 17. So we have:

√(18 x 17 x 34) = √(10404) = 102

The least possible positive integer-value of n such that [tex]\sqrt{18\cdot n \cdot 34}[/tex] is an integer is 17

The expression is given as:

[tex]\sqrt{18\cdot n \cdot 34}[/tex]

Expand the equation

[tex]\sqrt{18\cdot n \cdot 34} = \sqrt{2 \times 9 \times n \times 2 \times 17}[/tex]

Express 8 as 3^2

[tex]\sqrt{18\cdot n \cdot 34} = \sqrt{2 \times 3^2 \times n \times 2 \times 17}[/tex]

Rearrange the factors as follows:

[tex]\sqrt{18\cdot n \cdot 34} = \sqrt{2 \times 2\times 3^2 \times n \times 17}[/tex]

Express 2 * 2 as 2^2

[tex]\sqrt{18\cdot n \cdot 34} = \sqrt{2^2\times 3^2 \times n \times 17}[/tex]

Evaluate all exponents

[tex]\sqrt{18\cdot n \cdot 34} = 2\times 3 \times \sqrt{n \times 17}[/tex]

[tex]\sqrt{18\cdot n \cdot 34} = 6 \times \sqrt{n \times 17}[/tex]

For the expression to be an integer, then the radical must be a perfect square.

Given that the expression in the radical is [tex]{n \times 17[/tex], then the value of n must equal 17, at the very least

i.e.

[tex]n = 17[/tex]

Hence, the least possible positive integer-value of n is 17

Answer:

219.50

Step-by-step explanation

9.75% can be converted into 0.0975 so multiply  0.0975 by 200 you get 19.5. add 19.5 to 200 and you get 219.50

The value of the inverse function f⁻¹(x) at x = 3 is 0.631.

The inverse function is defined as a function obtained by reversing the given function.

The function f(x) = 3ˣ is a one-to-one function, which means it has an inverse function denoted by f⁻¹(x).

To find the value of f⁻¹(x) at x = 3, we need to solve the equation f(x) = 3ˣ = 3 for x.

3ˣ = 3

Divide both sides by 3:

3ˣ/3 = 3/3

Simplify:

3ˣ-1 = 1

Take the natural logarithm of both sides:

ln(3ˣ-1) = ln(1)

Simplify:

ln(3ˣ-1) = 0

Now we can solve for x:

ln(3ˣ-1) = 0

3ˣ-1 = e⁰ = 1

3ˣ = 2

x = log₃(2)

So, f⁻¹(3) = log₃(2) ≈ 0.631.

Therefore, the value of f⁻¹(x) at x = 3 is 0.631.

Answer: 4 miles = 16 min

4 miles : 16 min

Step-by-step explanation:

You have to multiply by the same number

The unit rate that describes Mr. Roble's trip to the store is 0.25 miles per minute.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Mr. Roble is traveling to the store and drives 4 miles in 16 minutes.

∴  The unit rate that describes Mr. Roble's trip to the store is,

= (4/16) miles per minute.

= 1/4 or 0.25 miles per minute.

Answer:

399.8 feet

Step-by-step explanation:

Since the angle of elevation of the top of the tower from the building is Ф = 37°, and the distance between the tower and the building is x = 275 feet. Let the upper part of the tower be h. These three components from a right-angled triangle with opposite side = h and adjacent side = x. So, by trigonometric ratios,

tanФ = h/x

h = xtanФ

= 275 feet × tan37°

= 275 feet × 0.7536

= 207.23 feet

Also, the angle of depression of the bottom of the tower from the building is Ф' = 35°, and the distance between the tower and the building is x = 275 feet. Let the lower part of the tower be h'. These three components from a right-angled triangle with opposite side = h' and adjacent side = x. So, by trigonometric ratios,

tanФ' = h'/x

h' = xtanФ'

= 275 feet × tan35°

= 275 feet × 0.7002

= 192.56 feet

So, the height of the tower, H = h + h'

= 207.23 feet + 192.56 feet

= 399.79 feet

≅ 399.8 feet

Answer: Choice C) 6x+5y = -20

You have the correct answer. Nice work.

=================================================

Work Shown:

y = (-6/5)x - 4

5y = 5*( (-6/5)x - 4 )

5y = 5*(-6/5)x - 5*4

5y = -6x - 20

6x+5y = -20

-----------

Explanation:

In the second step, I multiplied both sides by 5 to clear out the denominator. Two steps later (step 4), we have 5*(-6/5)x turn into -6x, so the fraction goes away.

In the last step, I added 6x to both sides to get the equation into standard form Ax+By = C. In this case, A = 6, B = 5, and C = -20.
