Calculate the values of a and b. Please help i cant understand it, i’ll give the brainliest for the person who answers correctly

Answers

Answer:

The value of a is 63° and the value of b is 27°

Step-by-step explanation:

In the given figure

∵ OA, OB, and OC are radii of the circle O

→ The radii of a circle are equal

OA = OB = OC

In Δ AOC

∵ OA = OC

Δ AOC is an isosceles triangle

→ Base angles of the isosceles triangle are equal

∵ ∠OAC and ∠OCA are the base angles of the triangle

m∠OAC = m∠OCA

∵ m∠OAC = a°

m∠OCA = a°

→ The sum of angles in any triangle is 180°

∵ a° + a° + m∠AOC = 180°

∵ m∠AOC = 54°

a° + a° + 54 = 180°

→ Add the like terms

∴ 2a° + 54 = 180°

→ Subtract 54 from both sides

∴ 2a° = 126°

→ Divide both sides by 2

∵ m∠OAC = m∠OCA = 126 ÷ 2

a° = 63

The value of a is 63°

In ΔBOC

∵ OB = OC

Δ BOC is an isosceles triangle

→ Base angles of the isosceles triangle are equal

∵ ∠OBC and ∠OCB are the base angles of the triangle

m∠OBC = m∠OCB

∵ m∠OBC = b°

m∠OCB = b°

∵ ∠AOC is an exterior angle of ΔBOC at the vertex O

→ The measure of the exterior angle equals the sum of the measure

    of the opposite interior angles to this vertex

∵ ∠OBC and ∠OCB are the opposite interior angle of ∠AOC

m∠OBC + m∠OCB = m∠AOC

→ Substitute their measures

b° + b° = 54°

→ Add the like terms

∴ 2b° = 54

→ Divide both sides by 2

b° = 27

The value of b is 27°

A store advertises 15% off an item that regularly sells for $300

what is the price of the item?

Answers

The item would sell for $255 if it had a 15 percent discount

For this problem, we're finding the percent of 300. To do that we:

1. Multiply 300 by 15.

300 x 15 = 4500

2. Divide 4500 by 100. (% = 100)

4500 / 100 = 45

Therefore, the unit price is 45. But we're not done. We need to subtract 45 by 300.

300 - 45 = 255

Now, our answer is 255 and the unit price is 45.

Step-by-step explanation

I got my driver's license last week

Just like we always talked about

'Cause you were so excited for me

To finally drive up to your house

But today I drove through the suburbs

Crying 'cause you weren't around

And you're probably with that blonde girl

Who always made me doubt

She's so much older than me

She's everything I'm insecure about

Yeah, today I drove through the suburbs

'Cause how could I ever love someone else?

And I know we weren't perfect but I've never felt this way for no one

And I just can't imagine how you could be so okay now that I'm gone

Guess you didn't mean what you wrote in that song about me

'Cause you said forever now I drive alone past your street

And all my friends are tired

Of hearing how much I miss you but

I kinda feel sorry for them

'Cause they'll never know you the way that I do

Yeah, today I drove through the suburbs

And pictured I was driving home to you

And I know we weren't perfect but I've never felt this way for no one

Oh, and I just can't imagine how you could be so okay now that I'm gone

Answers

Answer:

$1500

Step-by-step explanation:

If the television is marked down by 25%, it means that the price was reduced by 25%. This means that the television would be 100% - 25% = 75% of the original price.

The price of the television following the mark down=

The length of each side of polygon is: 11 and 13 units.

What is Polygon?

polygon, in geometry, any closed curve consisting of a set of line segments (sides) connected such that no two segments cross. The simplest polygons are triangles (three sides), quadrilaterals (four sides), and pentagons (five sides).

AS, we know all the sides of polygons are equal

7x-3= 4x+3

3x= 6

x=2.

Hence, the side of the triangle are:

7x-3= 7*2-3

      = 11 units

4x+5=4*2+5

      = 13 units

What are the coordinates of A after a dilation of 2/3 centered at the origin? Question 11 options:

A' =(−3/4, −3/2)

A' = (4/3, 2/3)

A' = (2, 1)

A' =(2/3, 2/3)

Answers

Answer:

The image of A(2, 1) after dilation by a scale factor of 2/3 will be: A'(4/3, 2/3) .

Step-by-step explanation:

Given

Point A (2, 1)

We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.

If the scale factor > 1, the image is enlarged If the scale factor is between 0 and 1, it gets shrunk If the scale factor = 1, the object and the image are congruent

Rule to calculate the dilation by a scale factor 2/3 centered at the origin

P(x, y) → P'(2/3x, 2/3y)

Here, P'(2/3, 2/3y) is the image of P(x, y).

It means the coordinates of the image can be determined by multiplying the coordinates of the original point by 2/3.

Thus,

A(2, 1) → A'(2/3(2), 2/3(1)) = A'(4/3, 2/3)

Therefore, the image of A(2, 1) after dilation by a scale factor of 2/3 will be: A'(4/3, 2/3) .

Patrick is riding his bike on a rectangular path around his city. There is a rest area at each of the path's four corners. The city map shows the corners marked with coordinates of (–2, 2), (1, 2), (1, –2), and (–2, –2). Each unit represents 2.5 miles.

Answers

Question:

What is the perimeter of the path, in miles?

Answer:

35 miles

Step-by-step explanation:

Given

Let the corners be ABCD

[tex]A = (-2,2)[/tex]

[tex]B = (1,2)[/tex]

[tex]C = (1,-2)[/tex]

[tex]D = (-2,-2)[/tex]

First, we calculate the perimeter of the corners in units.

This is done by calculating the distance between the corners.

Distance is calculated as:

[tex]D = \sqrt{(x_2 - x_1)^2 +(y_2 - y_1)^2 }[/tex]

For AB:

[tex](x_1,y_1) = (-2,2)[/tex]

[tex](x_2,y_2) = (1,2)[/tex]

[tex]D_1 = \sqrt{(1 - (-2))^2 +(2 - 2)^2 }[/tex]

[tex]D_1 = \sqrt{(1 +2)^2 +(0)^2 }[/tex]

[tex]D_1 = \sqrt{3^2}[/tex]

[tex]D_1 = 3[/tex]

For BC

[tex](x_1,y_1) = (1,2)[/tex]

[tex](x_2,y_2) = (1,-2)[/tex]

[tex]D_2 = \sqrt{(1 - 1)^2 +(-2 - 2)^2 }[/tex]

[tex]D_2 = \sqrt{(0)^2 +(-4)^2 }[/tex]

[tex]D_2 = \sqrt{16 }[/tex]

[tex]D_2 = 4[/tex]

For CD:

[tex](x_1,y_1) = (1,-2)[/tex]

[tex](x_2,y_2) = (-2,-2)[/tex]

[tex]D_3 = \sqrt{(-2 - 1)^2 +(-2 - (-2))^2 }[/tex]

[tex]D_3 = \sqrt{(-3)^2 +(-2 +2)^2 }[/tex]

[tex]D_3 = \sqrt{9 +0^2 }[/tex]

[tex]D_3 = \sqrt{9 }[/tex]

[tex]D_3 = 3[/tex]

For DA

[tex](x_1,y_1) = (-2,-2)[/tex]

[tex](x_2,y_2) = (-2,2)[/tex]

[tex]D_4 = \sqrt{(-2 - (-2))^2 +(2 - (-2))^2 }[/tex]

[tex]D_4 = \sqrt{(-2 +2)^2 +(2 +2))^2 }[/tex]

[tex]D_4 = \sqrt{0^2 +4^2 }[/tex]

[tex]D_4 = \sqrt{4^2 }[/tex]

[tex]D_4 = 4[/tex]

The perimeter P in units is:

[tex]P = D_1 + D_2 + D_3 + D_4[/tex]

[tex]P = 3+4+3+4[/tex]

[tex]P = 14[/tex]

Given that:

[tex]1\ units = 2.5\ miles[/tex]

Multiply both sides by 14

[tex]14 * 1\ units = 14 * 2.5\ miles[/tex]

[tex]14 \ units = 35\ miles[/tex]

Hence, the perimeter is 35 miles

Dividing negative exponents is almost the same as multiplying them, except you're doing the opposite: subtracting where you would have added and dividing where you would have multiplied. If the bases are the same, subtract the exponents. Remember to flip the exponent and make it positive, if needed.

Find the dimensions of the square.

Area = 441 cm²

Answers

Answer:

21 cm by 21 cm

Step-by-step explanation:

The formula for the area of a square is A = x^2, where x is the length of any one side of the square.  Here,

441 cm² = x²

This actually has two roots:  {√441, -√441), but since x must be positive here, to be a dimension of the square, we choose +√441, or +21.

The dimensions of the square are 21 cm by 21 cm.
