Answer 1

Answer:

radius = 7.5 cm

Step-by-step explanation:

Since M is the midpoint of the chord AB then OM is perpendicular to AB

Using Pythagoras' identity in right triangle OMB with hypotenuse OB, the radius of the circle, then

OB² = OM² + MB² = 4.5² + 6² = 20.25 + 36 = 56.25 ( take square root of both sides )

OB = radius = [tex]\sqrt{56.25}[/tex] = 7.5

Answer:

x = 98

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6 , then

sum = 180° × 4 = 720°

Sum the interior angles and equate to 720

x + 50 + 140 + 112 + x + x + 4 + 120 = 720, that is

3x + 426 = 720 ( subtract 426 from both sides )

3x = 294 ( divide both sides by 3 )

x = 98

The temperature at midnight is -5°C and is expected to drop 12°
by sunrise. What is the expected temperature at sunrise?

Answers

Answer:

-17 degrees Celsius.

Step-by-step explanation:

If the temperature at midnight is -5, and it is supposed to drop 12 more by sunrise, the 12 degrees are subtracted from the initial temperature.

-5 - 12 = -17 degrees by sunrise.

Juan compro un plasma en cuotas que costó $8000 si le faltan pagar 3 cuotas y ya pagó $6500 ¿cual es el valor de cada cuotas fijas?

Answers

Answer:

El valor de cada cuota fija es de $500.

Step-by-step explanation:

Para encontrar el valor de cada cuota fija, puedes calcular la diferencia entre lo que Juan ha pagado y el valor que costó el plasma para saber cuál es el monto que aún debe. Después, debes dividir la cantidad que aún debe pagar entre tres que es el número de cuota pendientes para encontrar el valor de cada cuota teniendo en cuenta que son fijas:

8000-6500=1500

1500/3=500

De acuerdo a esto, la respuesta es que el valor de cada cuota fija es de $500.

A certain high school has 1,488 students. If you subtract the number of girls from boys you get 78. Let x be the number of boys and y be the number of girls.

Answers

Answer:

boys = 705

girls = 783

Step-by-step explanation:

We are to find the number of boys and girls in the school

the answer can be determined using simultaneous equation

x = boys

y = girls

y - x = 78  equation 1

y + x  = 1488 equation 2

subtract equation 1 from 2

2x = 1410

x = 1410/2 = 705

Substitute for x in equation 1

y - 705 = 78

y = 705 + 78 = 783

Answers

Answer:

72°

Step-by-step explanation:

The full plate has a central angle of 360°.

7/35 × 360° = 72°

Answer:

72°

Step-by-step explanation:

In order to find the value of the central angle, you must first determine what percentage of the plate was broken.

Since 7 out of the total 35 inches of circumference were broken, you divide 7 by 35 ([tex]7/35[/tex]) and get 0.2, which means 20% of the plate is broken.

Now, knowing that a circle consists of 360°, you need to find 20% of 360.

Use the formula [tex]\frac{percent}{100} =\frac{part}{whole}[/tex] .

[tex]\frac{20}{100}=\frac{x}{360}[/tex]

360 x 20 = 7200

7200 ÷ 100 = 72

x = 72

So, the central angle is 72°.

Which equation matches the function shown in the graph?
A. y=2sin(1/2x)+1
B. y=3sin(2x)
C. y=2sin(2x)+1
D. y=3sin(1/2x)

Answers

Answer:

the answer is A. y=2sin(1/2x)+1

Step-by-step explanation:

I input all four functions on desmos (a graphing calculator), and saw that A. y=2sin(1/2x)+1 was similar to the function shown in the graph

The function that matches the graph is y= 2 sin(1/2x) +1.

What is graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given:

let y = A sin ([tex]\omega[/tex]x + Ф)+  k

T= 4π, w= 2π/T = 1/2

Now, midline= 1/2( max + min)

=1/2(3-1)= 2/2

k=1

and, A= 3-1 = 2

So, y= 2 sin(1/2x  + Ф) +1

as, Ф=0

So, y= 2 sin(1/2x) +1

Story: Dust by Charles Grayson 1 As Edwin rested his cheek against the side of his cow, Nelly, he could hear the wind whistling through the barn walls and see the air begin to darken with dust. Annie and Jewel were giggling as they played in the hayloft above him when one of the girls began to wheeze. Edwin quickly finished milking the cow and called to his sisters. Hurry up, girls, he said, another black blizzard is coming.2The wind suddenly picked up strength, and before Edwins eyes, the farmhouseonly 50 feet awaybecame nearly invisible. Without hesitation, Edwin grabbed two pieces of heavy twine, tied one around each girls waist, and then tied the two girls together. He took Annies hand and instructed her to hold tightly to Jewel. Leaning into the blinding wind, Edwin slowly navigated them back to the house.3Inside, Ma was relieved to see the children. With a sigh, she took the milk from Edwin, eyeing the familiar dust that she would try to skim off before serving the milk to her family. Although it was early morning, the dust storm outside made the small farmhouse dark and dismal. Edwin slapped the dirt from his jacket with his hands. He was weary of the dust, too, but he was smiling inside because tomorrow his father was coming home.4The next morning dawned clear and calm. Edwin swept the house while his mother worked in the yard, rescuing her daffodils from the dust that had drifted against the foundation of the house like gritty snow. The clatter of a rundown automobile heralded the arrival of Edwins father, and the boy raced outside.5The family gathered around Pa, who hugged each one of them tightly. He had been in Arizona for three weeks picking cotton. This spring the ground was hard and barren, and the constant dust storms made it impossible to cultivate crops. Pa had to find some way to earn moneyhis children were wearing tattered hand-me-downs, and his small herd of cattle was slowly starving.6When Ma asked about the work, Pa said that the wages he earned were far less than what had been promised. Still, hed brought home enough money to see them through another month. Eventually, the joy of being reunited with his family faded, and the careworn expression returned to Pas face. 7After Pa had been home a few days, Edwin overheard his parents having a serious discussion. I just dont know if I can leave our home, Ma said, a note of grief in her voice. Pa had heard there was work on commercial farms in California, where cotton, oranges, and other crops grew nearly year round.8I know its not like owning our own farm, but what choice do we have? Pa pleaded. Afterward, Ma went into the yard and stood for a long time by her beloved lilac bush, staring out at the desolate fields.9Later, Pa asked Edwin to ride the horse into town to purchase provisions. Edwin rode at a slow pace, thinking. He didnt like it when his parents argued, and he didnt like it when his father had to leave home to work. Most of all, Edwin wished there was something he could do to assist his family. At the store, he walked past the half-empty shelves to the back counter and asked Mr. Harburger for beans and flour.10As Edwin waited, something bright and orange caught his eye. It was an old advertisement on the shelf in front of hima photograph of a glistening orange grove with the words Sunny California splashed across the top. Edwin had never seen an orange grove before. Studying the picture, Edwins face brightened. Take it, Mr. Harburger said with a wink. At home, Edwin tacked the picture up next to his bed. One day, Edwin even caught his mother examining the photograph of the orange grove, smiling for the first time in a long time.11When autumn arrived, Edwins parents learned the government was offering to buy starving livestock for slaughter. Most farmers knew their animals could not survive another winter, so they accepted the offer in exchange for some much-needed cash. After a long discussion, Edwins parents did the same. Edwin sensed a change was coming.12The cow Nelly remained, but Edwin could see that she was becoming desperately thin. The next day, Edwin sold Nelly at the Baileys farm. The Baileys were doing better than most folks, though Edwin couldnt say why. He returned home with 16 dollars in his pocket and a little relief knowing that Nelly would be cared for.13Later that evening, Edwins parents made an important announcement: they would be packing whatever would fit into their old automobile and moving to California. Then Edwin made his own announcement. Here, he said, handing his father the 16 dollars.
