What is the sum of the interior angles of the polygon pictured below?

Answers

Answer:

360°

explanation:

the sum of interior angles of all quadrilaterals (polygons with four sides) is 360°. If you put a pen at any of the four corners and try to draw a line to any other corner, you'll find you can only make two triangles. And since the angle sum of triangles is 180°, 180 times 2 = 360

You are a first year police officer in Swanton, Ohio.

You are earning a monthly
salary of $4718.

Next year you will be given a raise to $62147 annually.

How much more per month will you earn your second year?

Answers

Answer:

$460.92

Step-by-step explanation:

First year monthly salary = $4,718

Second year annual salary = $62,147

Second year monthly salary = Annual salary / 12

= $62,147 / 12

= $5,178.92

How much more per month will you earn your second year?

Amount of increase in second year monthly salary = Second year monthly salary - First year monthly salary

= $5,178.92 - $4,718

= $460.92

En una escuela hay 12 paquetes,cada uno con 2 resma de papel de 500 hojas.Van a repartir las hojas en partes iguales entre los 10 grados dela escuela.¿cuantas hojas le darán a cada grado?

Answers

Answer:

A cada grado podrían darle, o 600 hojas en un caso.

O bien, 1200 hojas.

Step-by-step explanation:

Total de paquetes: 12

Cada paquete tiene, 2 resmas con 500 hojas lo cual se entendería que en cada resma hay 250 hojas

(Como son 2 resmas el total es de 500 hojas)

Si cada paquete tiene 500 hojas y hay 12 paquetes

500 hojas/paquete . 12 paquetes = 6000 hojas

6000 hojas / 10 grados = 600 hojas para cada grado.

Si pensamos que en 2 resmas de papel hay 500 hojas cada paquete tendría un total de 1000 hojas ya que:

2 resmas . 500 hojas/resma = 1000 hojas.

Si son 12 paquetes, 1000 hojas/paquete . 12 paquetes = 12000 hojas.

12000 hojas repartidas en 10 grados, son (12000 /10) = 1200 hojas.

QUESTION 1. Find the area. (Round to the nearest hundredth)


QUESTION 2. Trapezoid QRST has two right angles. A 5in altitude can be drawn dividing QRST into a rectangle and an isosceles right triangle. The longer side of the rectangle measures 9in. What is the area of the trapezoid ?

Answers

Answer:

The area of the trapezoid is 57.5 in.²

Step-by-step explanation:

The given information of the trapezoid are;

The vertices of the trapezoid = QRST

The altitude of the trapezoid = 5 in.

The shape the altitude divides the trapezoid into = A square and an isosceles right triangle

The long side of the rectangle = 9 in.

Therefore, we have;

The legs of an isosceles right triangle are equal

Given that one of the legs of the isosceles right triangle = The altitude of the triangle = 5 in.

Therefore, for the isosceles triangle, the length of the other leg = 5 in.

Therefore;

The area of the right triangle = 1/2 × Base × Height (altitude)

The area of the right triangle = 1/2 × Leg × leg = 1/2 × (Leg)²

∴ The area of the right triangle = 1/2 × 5 in. × 5 in. = 12.5 in.²

The length of the rectangle is given as l = 9 in.

The height of the rectangle, h = The altitude of the rectangle = 5 in.

The area of the rectangle, A = l × h

∴ The area of the rectangle, A = 9 in. × 5 in. = 45 in.²

The area of the trapezoid = The area of the right triangle + The area of the rectangle

The area of the trapezoid = 12.5 in.² + 45 in.² = 57.5 in.²

Use what you've learned to write the equation of a parabola that is narrower than y = x ,
2
opens downward, and has vertex (2, – 4).

Answers

Answer:

y = -a(x – 2)² – 4

a > 1

Example:

y = -2(x – 2)² – 4

Step-by-step explanation:

y = a(x – h)² + k

____________________

vetex: (h, k)

a: vertical reflection or stretch/compression

__________________________________

If it opens downward, has a vertex of (2, -4) and is narrower than y = x².

Then x² will have a negative coefficient of less than -1 and the input of x will be subtracted by the x value of the vertex which is 2, and the output will be added by the y value of the vertex which is -4.

Therefore y = -a(x – 2)² – 4 where a > 1

Hope this helps :)

Step-by-step explanation:

Supplementary angles are angles whose measures sum to 180°.

equation for supplementary angle~ a+b=180

Example:

2x+(2x–2)=180

4x–2=180

4x=182

x=45.5

Answer:

x = 100.5

Step-by-step explanation:

Supplementary angles are two angles that have a sum of 180°. THIS MEANS WE'RE ADDING.

We can use distributive property to solve this equation.

x + (x-21) = 180°.

x + x - 21 = 180°.

Now, we can combine like terms.

2x - 21 = 180.

Since there is a subtraction sign in front of the number 21, we do the opposite operation (addition).

Next, we add 21 to 180.

180 + 21 = 201.

2x = 201

Lastly, we divide 201 by 2.

The quotient is 100.5.

100.5 is the final answer.

Therefore, 100.5 is the value of x.

We can check our answer to make sure.

(100.5 - 21) + 100.5 =

79.5 + 100.5 = 180°.
