Find the unknown angles from
the given figure.
(2x-3)°
(2x-43)

Answers

Answer:

2x-3 = 29

8x = 128

x+7 = 23

Step-by-step explanation:

The sum of the angles of a triangle is 180

2x-3 + 8x+ x+7 = 180

Combine like terms

11x+4 = 180

Subtract 4 from each side

11x+4-4= 180-4

11x = 176

Divide by 11

11x/11 =176/11

x =16

2x-3 = 2*16-3 =32-3 = 29

8x = 8*16 =128

x+7 = 16+7 = 23

The graph shows the movement of a car from point A to point D, there are two slant line AB and CD.
(1) Calculate the speed of the car during the first 10 seconds.
(2) For how long did the car stop.
(3) What is the average speed of the car for the whole journey.
(4) Why the line BC is flat not slant.

Answers

Answer:

The answer is below

Step-by-step explanation:

a) The speed of the car during the first 10 seconds is equal to the slope of the line AB. The line AB passes through (0, 0) and (10, 200)

slope = (200 - 0)/(10 - 0) = 20 m/s

The speed of the car during the first 10 seconds is 20 m/s

b) The time for the car to move from point A to point D = 60 seconds

c) Distance from point A to B = 200 m, distance from C to D = 500 - 200 = 300 m, distance from B to C = 20 m/s * 20 s = 400 m

Total distance from A to D = 200 + 400 + 300 = 900 m

Average speed = total distance / total time = 900 m / 60 seconds = 15 m/s

d) line BC is flat because the car moves at a constant speed from point B to point C. That is the speed does not change.

- Use the numbers 2,165 and 4,428 to write and solve an equation that uses borrowing (regrouping).

Answers

Answer:

4,428-2,165=2,263

Step-by-step explanation:

you regroup the 2

The equation that uses numbers 2,165 and 4,428, and can be used to write and solve an equation that uses borrowing is 4,428-2,165=2,263.

What is Borrowing?

Borrowing in subtraction, like "carrying" in addition, means to take quantities from one number and assign them to the next. The 10 is borrowed from the next higher digit column in this approach to generate a positive difference in the next column.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='. An equation that uses borrowing or regrouping can be written as,

4,428 - 2,165 = 2,263

Hence, the equation that uses numbers 2,165 and 4,428, and can be used to write and solve an equation that uses borrowing is 4,428-2,165=2,263.

In a group of 120 recruits at the police academy 80 are college graduates and 25 are army veterans. If 15 of the recruits are both college graduate and army veterans as shown above, how many are neither college graduate nor army veterans?

Answers

Answer:

the number of recruits neither be college graduate and nor army veterans is 30

Step-by-step explanation:

The computation of the number of recruits neither be college graduate and nor army veterans is as follows;

= Total recruits - (college students + army veterans - both college graduates & army veterans)

= 120 recruits - (80 + 25 - 15)

= 120 recruits - 90

= 30

hence, the number of recruits neither be college graduate and nor army veterans is 30

Step-by-step explanation:

Si se invierten $ 500 a una tasa de 5% anual. Hallar el valor futuro a 3 años si el interés es compuesto trimestralmente.

Answers

Answer:

the future value is $5800.38

Step-by-step explanation:

Given that

The invested amount i.e present value is $500

The rate is 5 % per year so quarterly rate is 5% ÷ 4 = 1.25%

The time period is 3 per year so for quartely it is 3 × 4 = 12

We need to find out the future value

So as we know that

Future value = Present value × (1 + rate of interest)^time

= $500 × (1 + 0.0125)^12

= $580.38

hence, the future value is $5800.38

This family was situated in the Notch . . . .D. Up the chimney roared . . . .Passage: "The Ambitious Guest" by Nathaniel HawthorneNathaniel Hawthorne lived and wrote in the puritanical culture of 19th century New England. In the decade after he completed college, he spent most of his time in solitude writing his early short stories and a novel. When he was unable to support himself by writing, he tried several careers, but continued to write novels and short stories. Although he visited England and Italy, his best-known stories describe the gloom and loneliness of life in New England. He died in 1864.One September night a family had gathered round their hearth, and piled it high with the driftwood of mountain streams, the dry cones of the pine, and the splintered ruins of great trees that had come crashing down the precipice. Up the chimney roared the fire, and brightened the room with its broad blaze. The faces of the father and mother had a sober gladness; the children laughed; the eldest daughter was the image of Happiness at seventeen; and the aged grandmother, who sat knitting in the warmest place, was the image of Happiness grown old. They had found the "herb, heart's-ease," in the bleakest spot of all New England. This family was situated in the Notch of the White Hills, where the wind was sharp throughout the year, and pitilessly cold in the winter, giving their cottage all its fresh inclemency before it descended on the valley of the Saco. They dwelt in a cold spot and a dangerous one; for a mountain towered above their heads, so steep, that the stones would often rumble down its sides and startle them at midnight.The daughter had just uttered some simple jest that filled them all with mirth, when the wind came through the Notch and seemed to pause before their cottagerattling the door, with a sound of wailing and lamentation, before it passed into the valley.The family were glad again when they perceived that the latch was lifted by some traveller, whose footsteps had been unheard amid the dreary blast which heralded his approach, and wailed as he was entering, and went moaning away from the door.The door was opened by a young man. His face at first wore the melancholy expression, almost despondency, of one who travels a wild and bleak road, at nightfall and alone, but soon brightened up when he saw the kindly warmth of his reception. He felt his heart spring forward to meet them all, from the old woman, who wiped a chair with her apron, to the little child that held out its arms to him. One glance and smile laced the stranger on a footing of innocent familiarity with the eldest daughter."Ah, this fire is the right thing!" cried he; "especially when there is such a pleasant circle round it. I am quite benumbed; for the Notch is just like the pipe of a great pair of bellows; it has blown a terrible blast in my face all the way from Bartlett." Denise collects stuffed animals.
