The total cost of 5 boxes of pasta is $13.00. There are 12 ounces of pasta in each box. Each box of pasta costs the same amount. What is the maximum number of boxes that can be purchased with $65.00?

Answer:

A

Step-by-step explanation:

The arc length formula is:

Arc Length = [tex]\frac{\theta}{360}*2\pi r[/tex]

Where

[tex]\theta[/tex] is the angle measure of the arc, and

2πr is the circumference

Putting 84 in place of circumference and 14 in place of arc length, we can solve for [tex]\theta[/tex]:

Arc Length = [tex]\frac{\theta}{360}*2\pi r[/tex]

14 = [tex]\frac{\theta}{360}*(84)[/tex]

14 = [tex]\frac{84\theta}{360}[/tex]

[tex]14*360=84\theta\\5040=84\theta\\\theta=\frac{5040}{84}=60[/tex]

answer choice A is right.

The geometric transformation shown in the figure is reflection.

Reflection is a type of geometric transformation where the figure is flipped. In other words, a figure when undergoes reflection becomes it's mirror image.

here, we have,

Given is a set of lines in the music note.

Three line are drawn separating from a line.

In the first part, when we find the mirror image of the first part, we will get the second part.

Mirror images are found in the transformation of reflection.

So, here, we can say that reflection is the transformation here.

Hence the kind of geometric transformation shown in the line of music is reflection.

Answer:

The surface area of the rectangular prism is 700 units² ⇒ answer A

Step-by-step explanation:

* Lets revise how to find the surface are of the rectangular prism

- The rectangular prism has 6 rectangular faces

- Each two opposite faces are equal

- It has 4 side faces and 2 bases

* We can find the surface area of it by adding the area of

 the 6 faces

- In the problem

# The dimensions of the bases are 12 units and 14 units

# The dimensions of the side faces are 12 units and 7 units,

   14 units and 7 units

* Now lets find the area of each 2 equal faces

- In the bases

∵ Area of the rectangle = length × width

∴ The area of one base =  12 × 14 = 168 units²

∴ The area of the two bases = 2 × 168 = 336 units² ⇒ (1)

- In the two opposite faces with dimensions 12 units and 7 units

∵ The area of one face = 12 × 7 = 84 units²

∴ The area of the two faces = 2 × 84 = 168 unit² ⇒ (2)

- In the two opposite faces with dimensions 14 units and 7 units

∵ The area of one face = 14 × 7 = 98 units²

∴ The area of the two faces = 2 × 98 = 196 unit² ⇒ (3)

* To find the surface area of the prism add (1) , (2) , (3)

∴ The surface area of the prism = 336 + 168 + 196 = 700 units²

* The surface area of the rectangular prism is 700 units²

Answer:

5,000 meters * 1 kilometer / 1,000 meters = 5 kilometers answer is B

Step-by-step explanation:

Answer:

the answer is 5k

Step-by-step explanation:

Answer:

1. We already have the measure of the hypotenuse and one out of two acute angle, therefore:

sin53° = x/45 => x = sin53° · 45 ≈35.94

2. We already have one out of two legs of the triangle and one acute angle so we know that:

tan27° = 48/x => x = 48/tan27° ≈ 94.21

The value of x in the first right angle triangle is 27.08.

The value of x in the second right angle triangle is 24.46.

In order to determine the value of x in the first triangle, cos would be used.

Cos 53 = opposite / hypotenuse

Cos 53 = x / 45

0.7071 = x /45

x = 45 x 0.6018

x = 27.08

In order to determine the value of x in the second triangle, tan would be used.

Tan 27 = opposite / adjacent

Tan 27 = x / 48

x = 0.5095 x 48  

x = 24.46

Answer:

126 cm²

Step-by-step explanation:

The area (A) of a rhombus is calculated as

A = [tex]\frac{1}{2}[/tex] × d₁ × d₂ ← diagonals

The diagonals of a rhombus are perpendicular bisectors of each other, thus

d₁ = 7 + 7 = 14 and d₂ = 9 + 9 = 18, hence

A = 0.5 × 14 × 18 = 126 cm²

The area of the rhombus is equal to 126 cm². The correct option is B.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rhombus in a two-dimensional plane is called the area of the rhombus.

The area (A) of a rhombus is calculated as

A =  × d₁ × d₂ ← diagonals

The diagonals of a rhombus are perpendicular bisectors of each other,

d₁ = 7 + 7 = 14

d₂ = 9 + 9 = 18, hence

The area of the rhombus will be calculated as,

A =  0.5 × d₁ × d₂

A = 0.5 × 14 × 18

A = 126 cm²

Therefore, the area of the rhombus is equal to 126 cm². The correct option is B.

[tex]P(A|B) = \frac{40}{49}[/tex]

Step-by-step explanation:

In a probabilistic experiment, when two events A and B are dependent on each other, then the probability of occurrence A since B occurs is:

[tex]P(A|B) = \frac{P(A\ and\ B)}{P(B)}[/tex]

Then if [tex]P(A\ and\ B) = \frac{5}{7}[/tex] and [tex]P(B) = \frac{7}{8}[/tex] then:

[tex]P(A|B) = \frac{\frac{5}{7}}{\frac{7}{8}}\\\\P(A|B) = \frac{40}{49}[/tex]

Answer:

Correct choice is A. [tex]P(A|B)=\frac{40}{49}[/tex].

Step-by-step explanation:

Given that [tex]P(A\cap B)=\frac{5}{7}[/tex], [tex]P(B)=\frac{7}{8}[/tex].

Now using those values , we need to find the value of [tex]P(A|B)[/tex].

So apply the formula of conditional probability:

[tex]P(A\cap B)=P(B) \times P(A|B)[/tex]

Plug the given values into above formula,  we get:

[tex]\frac{5}{7}=\frac{7}{8} \times P(A|B)[/tex]

[tex]\frac{7}{8} \times P(A|B)=\frac{5}{7}[/tex]

[tex]P(A|B)=\frac{\frac{5}{7}}{\frac{7}{8}}[/tex]

[tex]P(A|B)=\frac{5}{7}\cdot\frac{8}{7}[/tex]

[tex]P(A|B)=\frac{40}{49}[/tex]

Hence correct choice is A. [tex]P(A|B)=\frac{40}{49}[/tex].

Answer:

The correct option is letter D.

Step-by-step explanation:

We have the following expression:

sqrt(y^3) + sqrt(9y^3) - 3y*sqrt(y)

We now that sqrt(a*b) = sqrt(a)sqrt(b)

Applying this rule, we have:

sqrt(y^3) + sqrt(9y^3) - 3y*sqrt(y)

sqrt(y^3) + 3sqrt(y^3) - 3y*sqrt(y)

Also we know that a*sqrt(b) = sqrt(b*a^2)

Applying this we have:

sqrt(y^3) + 3sqrt(y^3) - 3y*sqrt(y) = sqrt(y^3) + 3sqrt(y^3) - 3sqrt(y^3)

Then the result is:

sqrt(y^3) + 3sqrt(y^3) - 3sqrt(y^3) = sqrt(y^3) = y*sqrt(y)

The correct option is letter D.

So I could be completely wrong, or I could be completely right, but quadrilaterals interior angles equal 360 degrees.

So, if you ad up 98, 72, and 65 you end up with 235 degrees.

[tex]f\left(x\right)=(x+4)^{\frac{1}{3}}+4[/tex]

Step-by-step explanation:

Given function is [tex]f\left(x\right)=x^{\frac{1}{3}}[/tex]

Now it says that function is shifted 4 units to the left and 4 units up.

We need to find about which of the given choice is correct for the given transformation.

When f(x) is shifted "h" units left then we write f(x+h)

So [tex]f\left(x\right)=x^{\frac{1}{3}}[/tex] will change to

[tex]f\left(x\right)=(x+4)^{\frac{1}{3}}[/tex]

When f(x) is shifted "h" units up then we write f(x)+h

Answer:

2 hours,  142 miles

Step-by-step explanation:

Write a distance formula for both cars and then equate these formulas:

Car A:  y = 55x + 32  =  y = 42x + 58:  Car B

Then 55x + 32  =  y = 42x + 58  →  13x = 26, and so x = 2

That distance will be 55(2) + 32, or 142 miles.

The cars will reach the same point after 2 hours (first possible answer)

An equation is formed when two equal expressions. The correct option is A, 2hours, and 142 miles.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the equation for the distance covered by car A in x hours is y = 55x + 32, similarly, the equation for the distance covered by Car B in x hours is y=42x+58.

Now, to know at what time and at what distance the two cars will meet we need to solve the two equations. Since the car will cover the same distance we can write,

y = y

55x + 32 = 42x + 58

55x - 42x = 58 - 32

13x = 26

x = 2

Substitute the value of x in any one of the equations,

y = 55x + 32

y = 55(2) + 32

y = 110 + 32

y = 142

Thus, the car will meet after 2 hours, and the distance will be 142 miles.

Hence, the correct option is A, 2hours, and 142 miles.
