60 and 274.

Step-by-step explanation:

Answer: the andwer to that is C

Step-by-step explanation:

To determine which is the best buy, we need to first find the unit price of each

8 oz $2.40

Unit price

$2.40/8 = $0.3

1 oz = $0.3

24 oz $6.48

Unit price

$6.48/24 =$0.27

1 oz = $0.27

64 oz $14.08

Unit price

$14.08/64 =$0.22

From the above the best best buy is the one with the lowest price which is $0.22

The best buy is;

64 oz $14.08

and the unit rate is $0.22 per oz

Scale factor means ratio of the sides of the triangle then the measures of the indicated sides, and the scale factor of CB and AB exists ΔDEF - ΔABC; x = 1.5; CB = 3.9; AB = 3.

A scale factor is the amount by which an object is multiplied to produce a second object of different size but with the same appearance. The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

Each pair of given polygons are similar.

Similarity statement for the given polygons:

In ΔDEF and ΔABC,

∠D = ∠A (Angle)

∠E = ∠B  (Angle)

Therefore, ΔDEF  ΔABC (by AA similarity)

If two triangles are similar, then their sides are proportional.

[tex]$\Rightarrow \frac{D F}{A C}=\frac{D E}{A B}$[/tex]

[tex]$\Rightarrow \frac{2.4}{3.6}=\frac{2}{2 x}$[/tex]

By using cross multiplication, we get

⇒ 2.4 × 2x = 2 × 3.6

simplifying the above equation, we get

⇒ 4.8x = 7.2

⇒ x = 1.5

Therefore, the value of x = 1.5.

Substitute x = 1.5 in CB and AB,

CB = 3x – 0.6 = 3(1.5) – 0.6 = 3.9

AB = 2x = 2(1.5) = 3

Scale factor means ratio of the sides of the triangle.

⇒ DF/AC = 2.4/3.6 = 2/3

Therefore, the correct answer is option a) ΔDEF - ΔABC; x = 1.5; CB = 3.9; AB = 3.

The complete question is:

Each pair of polygons is similar. Write a similarity statement for the polygons. Then, find the measure of x, the measures of the indicated sides, and the scale factor.

[tex]$\overline{C B}$[/tex] and [tex]$\overline{A B}$[/tex]

Han is therefore mistaken in what he claims. The area is 8640 [tex]feet^{2}[/tex]

The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

Given Data

Let "x" represent the restaurant's actual space.

You are aware that the map's scale is 1 inch to 12 feet. As a fraction, this is written as follows:

[tex]\frac{1inch}{12feet}[/tex]

Calculate the restaurant's scale drawing area. Such is:

([tex]\frac{1inch}{12feet}[/tex]) ² = [tex]\frac{1inch^{2} }{144feet^{2} } }[/tex]

We can set up this percentage and then solve for "x" to determine the precise location of the restaurant because the restaurant's location is indicated on the map.

Such is:

[tex]\frac{144}{1}[/tex] = [tex]\frac{x}{60}[/tex]

1. The simple interest rate is 80%

2. The interest earned on the account after 10 years is $75

Simple interest can be defined as a mathematical or arithmetic method of calculating the charge of interest on a given loan.

The formula for simple interest is expressed as;

I = PRT/100

Where;

From the information given, we are to determine the interest rate, R

Substitute the values into the formula, we have;

320 = 200 × R × 2/100

Now, cross multiply, we have;

320(100) = 400R

Find the product of the values

400R = 32000

Divide both sides by the coefficient of the interest rate, we get

R = 32000/400

Find the quotient

R = 80%

If the interest for 2 years is $15

Then in 10 years = $x

cross multiply

x = 150/2

Find the quotient

x = $75

Hence, the rate is 80%

Answer:

Equation of the parabola:

The height of the arch 18 meters from the center is 6.75m

Explanation:

The arch feet are 72m apart and the origin half way between them. This means that the axis of symmetry (or the x.coordinate of the vertex) is x = 0

Since it's an arch, the parabola is concave down, with it's maximum at the vertex, y = 9. This means that the vertex is at (0, 9). Also, we can see that the y-intercept is y = 9

Finally, we know the two roots of the parabola: x = -36 and x = 36. This is because the points x = -36 and x = 36 are 72m apart, with the center at the original, as the problem says. SInce x = 36 is a root, this means that at that point the y value is 0.

With all this, we can try to find the general form of a parabola. The general form is:

c is the y-intercept. We know that c = 9

We can find the value of b, because we know the coordinates of the vertex. The x-coordinate of the vertex is:

SInce the x-coordinate of the vertex is x = 0

If we solve:

So far we have:

Finally, to find a, we can use the point (36, 0) (one of the roots)

And solve:

Thus, the equation of the arch is:

Evaluating this equation for x = 18, we can find the height of the arch:

The other endpoint of the segment is (7, 14)

From the question, we have:

On the segment, we have the following endpoints

Endpoint 1, A = (-3,-2)

Midpoint, M = (2,6)

The midpoint of the segment is calculated using

Midpoint (x, y) = 1/2 * (x1 + x2, y1 + y2)

Where

(x1, y1) = (-3,-2)

(x, y) = (2,6)

Substitute the known values in the above equation

So, we have

(2, 6) = 1/2 * (-3 + x, -2 + y)

Multiply both sides of the equation by 2

So, we have

(4, 12) = (-3 + x, -2 + y)

By comparison, we have

-3 + x = 4

-2 + y = 12

Evaluate the like terms in the above equation

So, we have

x = 7

y = 14

When the above solution is represented as a coordinate, we have the following

(x, y) = (7, 14)

Hence, the other endpoint of the segment where the segment has the endpoint (-3,-2) and midpoint (2,6) is (7, 14)

Jill's position =80th

Nathan's position = Percentile rank  of 80

The above means that

Nathan's position = 80 percentage of the number of students in the class

So, we have the following equation

Nathan's position = 80 percentage of 200

Rewrite as

Nathan's position = 80 percentage * 200

Express as percentage
