Answer:

Number of months= 12 months

Step-by-step explanation:

Giving the following information:

One time fee= $20

Monthly fee= $7.5

Total cost= $115

To calculate the number of months, we need to use the following formula:

Number of months= (total cost - one time fee) / monthly fee

Number of months= (115 - 20) / 7.5

Number of months= 12.67

Number of months= 12 months

The equivalent expressions for [tex]\sqrt{\frac{36a^8}{225a^2} }[/tex] are A, B and E.

Square root of a number is the value such that the value when multiplied to itself two times gives the original number.

It is denoted by the symbol √.

Given expression is [tex]\sqrt{\frac{36a^8}{225a^2} }[/tex].

There are five expressions in the left.

A. [tex]\sqrt{\frac{2(2)(3)(3)(a)(a)(a)(a)(a)(a)(a)(a)}{3(3)(5)(5)(a)(a)} }[/tex]

Here we have to multiply the terms in the numerator as well as in the denominator.

2(2)(3)(3) = 36 and 3(3)(5)(5) = 225

So this expression is equivalent to the given  [tex]\sqrt{\frac{36a^8}{225a^2} }[/tex].

B. [tex]\sqrt{\frac{4a^6}{25} }[/tex]

We know that, greatest common factor of 36 and 225 is 9.

36/9 = 4 and 225 / 9 = 25

Also a⁸ / a² = a⁸⁻² = a⁶

So this is also an equivalent expression.

C. [tex]\frac{6}{25} \sqrt{ \frac{a^8}{a^2} }[/tex]

This is not equivalent since √225 = 15, not 25.

D. [tex]\frac{6}{15} a^4[/tex]

This is also not equivalent since  [tex]\sqrt{ \frac{a^8}{a^2} }[/tex] = [tex]\sqrt{a^6}[/tex] = a³, not a⁴.

E. [tex]\frac{2}{5} a^3[/tex]

This is equivalent expression since √36 = 6 and √225 = 15.

[tex]\sqrt{\frac{36a^8}{225a^2} }[/tex] = [tex]\frac{6}{15}[/tex] [tex]\sqrt{ \frac{a^8}{a^2} }[/tex] = [tex]\frac{2}{5}[/tex] [tex]\sqrt{a^6}[/tex] = [tex]\frac{2}{5} a^3[/tex]

Hence the equivalent expressions are A, B and E.

Your question is confusing. The image of the question is attached below.

Answer:

B. 2800 sq mm

Step-by-step explanation:

Given the following data;

Length = 80 mm

Width = 70 mm

Area of rectangle is given by the formula;

Area of rectangle = length * width

Substituting into the formula, we have;

Area of rectangle = 80 * 70

Area of rectangle = 5600 mm²

Since the paper (area of rectangle) was halved, we would divide by 2;

Area of each half = 5600/2

Area of each half = 2800 sq mm.

Answer:

H and K in the equations of a circle represents the coordinates of it's center point.

Step-by-step explanation:

The variables h and k represent the coordinates of the center of the circle

In the equations of a circle in standard form, [tex](x - h)^2 + (y - k)^2 = r^2[/tex].

The value of h corresponds to the x-coordinate of the center, while the value of k represents the y-coordinate of the center. The center of the circle is denoted as (h, k).

By specifying the values of h and k, we can determine the exact location of the center of the circle on the coordinate plane. These coordinates help identify the position of the circle in relation to the x and y axes.

For example, if the equation of a circle is [tex](x - 2)^2 + (y + 3)^2 = 16[/tex], the center of the circle is located at the point (2, -3), with h = 2 and k = -3.

Understanding the significance of h and k allows us to identify the center of a circle and provides valuable information for analyzing and graphing circles in the coordinate plane.

Therefore, the variables h and k represent the coordinates of the center of the circle

To express in simpler form, divide both numerator and denominator by 6

2/5

Answer:

When we have something like:

[tex]\sqrt[n]{x}[/tex]

It is called the n-th root of x.

Where x is called the radicand, and n is called the index.

Then the term:

[tex]\sqrt[4]{16}[/tex]

is called the fourth root of 16.

And in this case, we can see that the index is 4, and the radicand is 16.

At the end, we have the question: what is the 4th root of 16?

this is:

[tex]\sqrt[4]{16} = \sqrt[4]{4*4} = \sqrt[4]{2*2*2*2} = 2[/tex]

The 4th root of 16 is equal to 2.

Answer:

It should be 1000 miles

Step-by-step explanation:

If you draw the picture out, you will find as the x-axis part is the same, so the distance will simply be 12 -2 = 10 units, and 1unit = 100 miles, so distance is 100 * 10 = 1000 miles.
