1. y = 5x + 1
4x + y = 10

Step-by-step explanation:

The complete question:

What is the value of y in the formula shown when x = [tex]\dfrac{4}{5}[/tex] ?

[tex]y=\dfrac{4}{x}+\sqrt{x+0.2}-5x[/tex]

We have,

[tex]\dfrac{4}{x}+\sqrt{x+0.2}-5x[/tex]       ...... (1)

To find, the value of y = ?

Put x = [tex]\dfrac{4}{5}[/tex] in equation (1), we get

[tex]y=\dfrac{4}{\dfrac{4}{5}}+\sqrt{\dfrac{4}{5}+0.2}-5(\dfrac{4}{5})[/tex]

[tex]=5+\sqrt{0.8+0.2}-4[/tex]

[tex]=1+\sqrt{1}[/tex]

= 1 + 1

= 2

Thus, the value of y is equal to 2.

Answer:

31.94 miles

Step-by-step explanation:

we know that

The circumference of a tire represents the distance traveled by the vehicle in one revolution

so

by proportion

Find out the distance traveled by the vehicle in 23,000 revolutions

[tex]\frac{88}{1}\ \frac{in}{rev}=\frac{x}{23,000}\ \frac{in}{rev}\\\\x=88(23,000)\\\\x=2,024,000\ in[/tex]

Convert inches to miles

Remember that

[tex]1\ mile=63,360\ inches[/tex]

To convert inches to miles divided by 63,360

therefore

[tex]2,024,000\ in=2,024,000/63,360=31.94\ miles[/tex]

It will need 864 meters³ of water to fill it completely

Step-by-step explanation:

The formula of the volume of a prism is V = B h, where

The swimming pool is shaped a prism

∵ The length of each side of the four sides is 12 meters

- That means its base is shaped a square with side length 12 meters

∵ Area of a square = (side)²

∴ The area of the base of the swimming pool = (12)² = 144 meters²

∴ B = 144

∵ The pool is 6 meters deep

- That means its height is 6 meters

∴ h = 6

The volume of the water in the swimming pool is equal to the volume of the swimming pool because it will be needed to fill completely

∴ The volume of the water = B h

∴ The volume of the water = 144(6)

∴ The volume of the water = 864 meters³

It will need 864 meters³ of water to fill it completely

Answer:

45 metres

Step-by-step explanation:

You have to get the base to answer the question.

Do this by dividing 315 by 15 then timesing by 2

You get 42.

Do 42^2 = 1764

Do 15 ^2 = 225

Because you want the hypotenuse you add them

1764 + 225 =1989

Do the square root of 1989 which is 45 to the nearest metre

Answer:

25.80

Step-by-step explanation:

Area = 315 [tex]m^{2}[/tex]

Area = l*b

315 = 15 *b

b= 315/15

b = 21

From Right angled Triangle ,

Hypotenuse square = side square + side square

[tex]x^{2}[/tex] = [tex]21^{2}[/tex] + [tex]15^{2}[/tex]

[tex]x^{2}[/tex] = 441 + 225

[tex]x^{2}[/tex] = 666

apply sq root on both sides, the we get

[tex]\sqrt{x^{2}} = \sqrt{666}[/tex]

x= 25.80

We can conclude that, if two pairs of corresponding sides and the corresponding included angles are congruent, the two triangles will be congruent.

Given that, two pairs of corresponding sides and the corresponding included angles are congruent.

Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.

If two pairs of corresponding sides are equal and corresponding included angles are equal.

By SAS congruence theorem, two triangles are congruent.

Therefore, we can conclude that, if two pairs of corresponding sides and the corresponding included angles are congruent, the two triangles will be congruent.

Answer:

The bowling ball has only potential energy as it sits on top of a building.

The potential energy "stored" in the bowling ball will convert to kinetic energy as the ball is pushed from the top of the building and starts to fall.

The energy spent in raising the ball against gravity to the top of the building is equal to the amount of potential energy "stored" in the bowling ball.

Therefore the bowling ball will have more potential energy as it sits on top of the building.

Step-by-step explanation:

The bowling ball has only potential energy as it sits on top of a building.

The potential energy "stored" in the bowling ball will convert to kinetic energy as the ball is pushed from the top of the building and starts to fall.

The energy spent in raising the ball against gravity to the top of the building is equal to the amount of potential energy "stored" in the bowling ball.

Therefore the bowling ball will have more potential energy as it sits on top of the building.

Answer:

Before the ball hits the ground it has more potential energy but when is going down it looses potential energy and creates kinetic energy so when the ball hits the floor it would have more kinetic energy.

Answer:

1)  ∠DCE = (180  - x)°

2)   x  = 60°

Step-by-step explanation:

Here, given :  Lines AD and BE intersect at point C

(a)  Now, as we know, c BE is a straight line.

⇒∠BCD + ∠DCE = 180 °  (LINEAR PAIR)

⇒x °  + ∠DCE = 180 °

or, ∠DCE = (180  - x)° ....... (1)

(b) ∠DCE  = 120°

Putting the value in the equation (1), we get:

120°  = (180  - x)°

or, x =  180 - 120° = 60°

or, x  = 60°

Answer:

Therefore 6th year his income was $19,700.

Step-by-step explanation:

Given, Joe's annual income has been increasing in some dollar amount . The first year his income was $15,200 and 4th  year his income was $17,900.

A=$17900, P= $15,200 and n = 3 year

[tex]A= P(1+\frac{r}{100} )^n[/tex]

[tex]\Leftrightarrow 17900=15200(1+\frac{r}{100})^3[/tex]

[tex]\Leftrightarrow (1+\frac{r}{100})^3=\frac{17900}{15200}[/tex]

[tex]\Leftrightarrow (1+\frac{r}{100})=(\frac{17900}{15200})^{\frac{1}{3} }[/tex]

[tex]\Leftrightarrow \frac{r}{100}=(\frac{17900}{15200})^{\frac{1}{3} }-1[/tex]

[tex]\Leftrightarrow r=5.60[/tex]

Let  [tex]t^{th}[/tex] year Joe's income was $19,700.

[tex]\therefore 19700=15,200(1+\frac{5.60}{100} )^{t-1}[/tex]

[tex]\Leftrightarrow 1.296= (1+0.056)^{t-1}[/tex]

[tex]\Leftrightarrow 1.296= (1.056)^{t-1}[/tex]

[tex]\Leftrightarrow log(1.296)= (t-1)log(1.056)[/tex]

[tex]\Leftrightarrow \frac{log(1.296)}{log(1.056)}= (t-1)[/tex]

[tex]\Leftrightarrow t-1= 4.75[/tex]

[tex]\Leftrightarrow t= 4.75+1[/tex]

[tex]\Leftrightarrow t = 5.75[/tex] ≈6

Therefore 6th year his income was $19,700.

Answer:

Senior citizen tickets = 9

Student tickets = 10

Step-by-step explanation:

We begin by converting the question into simultaneous linear equations;

Senior citizen tickets = a

Student tickets = b

4a + 6b = 96

8a + 13b = 202

to find a,

if 4a +6b = 96

a = 96/4 - 6b/4

a = 24 - 1.5b

We now substitute this into the second equation

8(24 - 1.5b) + 13b = 202

192 - 12b + 13b = 202

b = 202 - 192

b = 10

We now put the value of b in either equation

4a + 6b = 96

4a + 6(10) = 96

4a + 60 = 96

4a = 96 - 60

4a = 36

a = 9

2 + 1.4 + 1.3 + 1.2 + 4.1 + 1.3 + 1.4 + 3

A Dilation factor of 3 means that all dimensions of the figure are three times larger than those of the original figure. This applies to every dimension of the figure including height, width, and depth (if applicable). An example is a rectangle with original measurements 2 cm by 4 cm becoming 6 cm by 12 cm after dilation.

When a figure undergoes a dilation, all its dimensions are altered by the dilation factor.

In this case, the dilation factor is 3, which means that each dimension of the figure is three times larger than before.

It is important to note that this applies to all dimensions: height, width, and depth (if applicable).

For instance, suppose you have a rectangle with a height of 2 cm and width of 4 cm.

If the rectangle is dilated by a factor of 3, the new dimensions would be 6 cm (2 cm * 3) for height and 12 cm (4 cm * 3) for width.

Answer:

46

Step-by-step explanation:

47.84 / 1.04, which is 46

The opening price of Company A's stock before the 4% increase to the closing price of $47.84 was $46.00.

To calculate the opening price of Company A's stock at the beginning of the day, before the 4% gain, we need to work backwards from the closing price. Since the stock closed at $47.84 after gaining 4%, we can represent the closing price as 104% of the opening price. Thus, the equation to find the opening price (OP) is:

OP x1.04 = $47.84

Now we solve for OP:

OP = $47.84 / 1.04

OP = $46.00

The opening price of Company A's stock at the beginning of the day was $46.00.

-2x-3y

Step-by-step explanation:

-1/4(8x+12y)

-8/4x-12/4y

-2x-3y

Final answer:

The expression -1/4(8x+12y) is expanded by distributing -1/4 to both 8x and 12y, resulting in the equivalent expression -2x - 3y.

Explanation:

To expand the expression -1/4(8x+12y), you need to distribute the term outside the parenthesis (-1/4) to each term inside the parenthesis. This process is known as the distributive property of multiplication over addition. Here's the step-by-step process:

In conclusion, the equivalent expression after expanding -1/4(8x+12y) is -2x - 3y.
