What is 1/2x1/2 in fractions?

Answers

I think it is 2/4 but I might be wrong

The requried multiplication of 1/2 and 1/2 is equal to 1/4. This means that if you divide a whole into 4 equal parts and then take one of those parts.

To multiply fractions, you simply multiply the numerators together and the denominators together.

The multiplication of 1/2 and 1/2 is calculated as follows:

(1/2) * (1/2) = (1 * 1) / (2 * 2)
                = 1 / 4

Therefore, the multiplication of 1/2 and 1/2 is equal to 1/4. This means that if you divide a whole into 4 equal parts and then take one of those parts, it's equivalent to multiplying 1/2 by 1/2.

Write the equation of a line that is parallel to Y =3x-2 that passes through (4,1)

Answers

Answer:

The equation of the line is y = 3x - 11.

Step-by-step explanation:

We are given the equation of a line:

[tex]\bullet \ \ \ y = 3x -2[/tex]

We are also given a point at which the line passes through.

[tex]\bullet \ \ \ (4, 1)[/tex]

With parallel lines, it is important to note:

Parallel lines have the same slope.Parallel lines must have a different y-intercept.

We can use the point-slope equation to find the equation of the line:

[tex]\displaystyle y-y_1 =m(x-x_1)\\\\y - 1 = 3(x - 4)\\\\y - 1 = 3x - 12\\\\y - 1 + 1 = 3x - 12 + 1\\\\y = 3x - 11[/tex]

Therefore, the line that is parallel to y = 3x - 2 and passes through the point (4, 1) is y = 3x - 11.

What is the measure of angle A in the triangle?

Answers

Answer:

Angle A = 50°

Step-by-step explanation:

(2x - 10) + (x + 30) + 70 = 180

3x = 180 + 10 - 30 - 70

3x = 90

x = 90/3

x = 30

A = 2x -10

A = (2 * 30) - 10

A = 60 - 10

A = 50

8. Using the formula: f(n) = f(1) + d(n-1), find f(9) for the ordered pairs
in #7.

Answers

Answer:

8. Arithmetic Progression

9. [tex]f(9) = 300[/tex]

Step-by-step explanation:

Given

[tex]\{(1,55)\ (2, 45)\ (3, 35)\ (4, 25)\}[/tex]

Solving (8): Arithmetic or Geometric

We start by checking if it is arithmetic by checking for common difference (d).

[tex]d = y_2 - y_1 = y_3 - y_2 = y_4 - y_3[/tex]

This gives:

[tex]d = 45 - 55 = 35 - 45 = 25 - 35[/tex]

[tex]d = -10 = -10 = -10[/tex]

[tex]d=-10[/tex]

Because the common difference is equal, then it is an arithmetic progression

Solving (8):

[tex]f(n) = f(1) + f(n-1)[/tex]

To find f(9), we substitute 9 for n

[tex]f(9) = f(1) + f(9-1)[/tex]

[tex]f(9) = f(1) + f(8)[/tex]

We need to solve for f(8); substitute 8 for n

[tex]f(8) = f(1) + f(8 - 1)[/tex]

[tex]f(8) = f(1) + f(7)[/tex]

We need to solve for f(7); substitute 7 for n

[tex]f(7) = f(1) + f(7 - 1)[/tex]

[tex]f(7) = f(1) + f(6)[/tex]

We need to solve for f(6); substitute 6 for n

[tex]f(6) = f(1) + f(6 - 1)[/tex]

[tex]f(6) = f(1) + f(5)[/tex]

We need to solve for f(5); substitute 6 for n

[tex]f(5) = f(1) + f(5 - 1)[/tex]

[tex]f(5) = f(1) + f(4)[/tex]

From the function, f(4) = 25 and f(1) = 55.

So:

[tex]f(5)=55 + 25[/tex]

[tex]f(5)=80[/tex]

[tex]f(6) = f(1) + f(5)[/tex]

[tex]f(6) = 55 + 80[/tex]

[tex]f(6) = 135[/tex]

[tex]f(7) = f(1) + f(6)[/tex]

[tex]f(7) = 55 + 135[/tex]

[tex]f(7) = 190[/tex]

[tex]f(8) = f(1) + f(7)[/tex]

[tex]f(8) = 55 + 190[/tex]

[tex]f(8) = 245[/tex]

[tex]f(9) = f(1) + f(8)[/tex]

[tex]f(9) = 55 + 245[/tex]

[tex]f(9) = 300[/tex]

A person bought some cosmetics from wholesale market at the rate of Rs 360 per dozen he sells it at Rs 80 a pair find the gain percent solve step by step​

Answers

Given,

CP of cosmetics = Rs 360 per dozen

SP of a pair of cosmetics = Rs 80

We need to find the profit percentage.

Solution,

We know that,

1 dozen = 12 items

CP of 1 cosmetic = 360/12 = Rs 30

SP of 1 cosmetic = 80/2 = Rs 40

Profit = SP-CP

= Rs 40 - Rs 30

= Rs 10

Profit percentage is given by :

[tex]\%=\dfrac{profit}{CP}\times 100\\\\=\dfrac{10}{30}\times 100\\\\=33.34\%[/tex]

So, the profit percentage is 33.34%.

Which equation represents the line that is perpendicular to y = 1/4 and passes through (-6-9)?
OA. x= -9
OB. x=-6
Oc. y=9
OD. y= -4

Answers

Answer:

B. x = -6

Step-by-step explanation:

A line with the equation, y = ¼, is a horizontal line. Therefore, the line that is perpendicular to it would be a vertical line, which can be represented by the equation, x = a. Where, a is the x-value or the point where the vertical line intersects the x-axis. This x-coordinate remains the same for every point on the vertical line.

Thus, since the perpendicular line passes through (-6, -9), therefore, the value of a = -6.

Thus, the equation of the perpendicular line would be:

x = -6
