What is the value of x in the right triangle below? Show your work and round your answer to the nearest hundredth. ​

Answers

The length of the hypothenuse or the value of x is equal to 19.53

This is a right angle triangle and since we have a missing side, we should list our data first and find an option to solve this.

Data;

hypothenuse = xadjacent = 11.2opposite = 16Pythagoras's Theorem

To solve this problem, we have to use Pythagoras's theorem which is used to find the missing side in a right angle triangle if we have at least two sides.

The formula for this is

x^2 = y^2 + z^2

Let's substitute the values and solve for the missing side.

[tex]x^2 = 16^2 + 11.2^2 \\x^2 = 256 + 125.44\\x^2 = 381.44\\x = \sqrt{381.44} \\x = 19.53[/tex]

The length of the hypothenuse or the value of x is equal to 19.53.

the diagram shows the cross-section of a wall of a cinema.

Answers

Answer:

280 m²£133

Step-by-step explanation:

The area of the wall is the sum of the areas of the different sections of the wall. The cost to paint it will be the product of the cost of a tin of paint and the number of tins required.

__

Here, the shape of the wall can be divided into two trapezoids and a rectangle. Each shape has a corresponding area formula. Left-to-right, their areas are ...

Left Trapezoid

  A = 1/2(b1 +b2)h

  A = 1/2(10 m +11 m)(4 m) = 42 m²

Middle Rectangle

  A = LW

  A = (13 m)(11 m) = 143 m²

Right Trapezoid

  A = 1/2(b1 +b2)h

  A = 1/2(11 m +8 m)(10 m) = 95 m²

Wall Area

The total area to be painted is the sum of the above areas:

  total area = 42 m² +143 m² +95 m² = 280 m²

The area that needs to be painted is 280 m².

__

A tin of paint covers 15 m², so the number of tins needed is ...

  (15 m²)t = 280 m²

  t = 280/15 = 18 2/3 . . . . . . divide by the coefficient of t

We can only buy whole tins, so we need to buy 19 tins. Their cost will be ...

  (£7 /tin)(19 tins) = £133

It will cost £133 to paint the wall.

Step-by-step explanation:

The solution of system of equations is (3.5, 3.5).

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

1) 1/2 (12x+8) -1/3 (24)=1/4 (16x+40)

6x+4-8=4x+10

6x-4=4x+10

6x-4x=10+4

2x=14

x=7

Therefore, the value of x is 7.

3) y=3x-7 -------(i) and -y=x-7 -------(ii)

Substitute equation (i) in equation (ii), we get

-(3x-7)=x-7

-3x+7=x-7

x+3x=7+7

4x=14

x=14/4

x=3.5

Substitute x=3.5 in equation (i), we get

y=3×3.5-7

y=10.5-7

y=3.5

So, the solution is (3.5, 3.5)

4) Production of chairs from Anthony

(2, 10) and (5, 25)

Here, m=(25-10)/(5-2)

= 15/3

= 5

Substitute m=5 and (x, y)=(2, 10) in y=mx+c, we get

10=5(2)+c

c=0

Substitute m=5 and c=0 in y=mx+c, we get y=5x

Production of chairs from Billy

(1, 2) and (4, 8)

Here, m=(8-2)/(4-1)

= 6/3

= 2

Substitute m=2 and (x, y)=(1, 2) in y=mx+c, we get

2=2(1)+c

c=0

Substitute m=2 and c=0 in y=mx+c, we get y=2x

When y=18

Production of chairs from Billy 18=5x

x=3.6

When y=18

Production of chairs from Anthony

18=2x

x=9

Therefore, the solution of system of equations is (3.5, 3.5).

For the expression [tex]2x-5[/tex], evaluate it for [tex]x = (0, 1, 2, 3, 4, 5)[/tex].

From the evaluated set of values the mean absolute deviation rounded off to the nearest tenth is:

-------------------------------------------------------------------------------------------------------

Evaluating the expression for the given values of x:

[tex]x=0 \implies 2(0)-5=-5[/tex]

[tex]x=1 \implies 2(1)-5=-3[/tex]

[tex]x=2 \implies 2(2)-5=-1[/tex]

[tex]x=3 \implies 2(3)-5=1[/tex]

[tex]x=5 \implies 2(5)-5=5[/tex]

Evaluated set of values: -5, -3, -1, 1, 3, 5

To find the Mean Absolute Deviation (MAD):

Calculate the mean (by summing the data values and dividing by the number of values)Subtract the mean from each value in the data set and take the absolute value of each result.Sum the absolute values from step 2.Divide by the number of values.

[tex]\sf Mean=\dfrac{(-5)+(-3)+(-1)+1+3+5}{6}=0[/tex]

The measures of the angles of triangle PQR can be represented in terms of x
The measure of angle P is (2x)
The measure of angle Q is
(x+17)
The measure of angle R is (x-21)
Create an equation that can be used to find the measure of each angle.

Answers

Answer:2x+(x+17)+(x-21)=180

Step-by-step explanation:

Angles in a triangle add to 180 degrees.

The equation that can be used to find the measure of each angle is 2x + x + 17 + x - 21 = 180

How to create an equation to determine the angles?

The given parameters are:

P = 2x

Q = x + 17

R = x - 21

The sum of angles in a triangle is 180.

So, we have:

P + Q + R = 180

Substitute known values

2x + x + 17 + x - 21 = 180

Hence, the equation that can be used to find the measure of each angle is 2x + x + 17 + x - 21 = 180

Answers

Answer:

~6.534653% of randomly selected a book from his bag (I don't know how many decimals you need)

Step-by-step explanation:

Basically you just do (66 (books) /1010 (total items)) * 100 to find your answer because out of the total 1010 items in that bag there is only 66 that are books so its (66/1010)*100 to find your answer, the *100 is added to find the percentage.

9. A cooler contains 4.5 gallons of water and is filling up
at a rate of 0.1 gallons per second. A second cooler
contains 7 gallons of water and is draining at a rate of
0.25 gallons per second. Which could be used to
determine the number of seconds it would take for each
cooler to contain the same amount of water?

Answers

The equation that can be used to determine when each cooler would contain the same amount of water is 2.5 = 0.75t.

When the coolers would have the same amount of water?

Equation that can be used to determine the amount of water in the first cooler at time t : 4.5 + 0.1t

Equation that can be used to determine the amount of water in the second cooler at time t : 7 + 0.25t

Where t represents seconds

When they have the same amount of water, the two above equations would be equal

4.5 + 0.1t = 7 + 0.25t

Combine similar terms

7 - 4.5 = 0.1t - 0.25t

2.5 = 0.75t

A bird flies up and then down again, approximately following the
parabola y = -0.5x^2 + 15x. y measures height in feet.
Approximately what is the highest height that the bird flew to?

Answers

Answer:

112.5 ft

Step-by-step explanation:

The maximum is achieved at vertex of parabola.

The x- coordinate of the vertex is determined by x = - b/(2a).

x = - 15/(-0.5*2) = 15

The maximum height is the corresponding y- coordinate

y = - 0.5(15²) + 15(15) = 112.5 ft

Find vertex

x coordinate

-b/2a-15/-115

Y coordinate (Max height)

y=-0.5(15)²+15(15)y=-0.5(225)+225y=112.5ft

An outlet has a current of 10 amperes and a resistance of 14 ohms. Find the voltage difference.

Answers

V = IR
V = (10 amperes • 14 ohms)
V = 140 volts

The voltage difference for an outlet will be 140 volts.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

For an outlet,

Current (I) = 10 ampere

Resistance (R) = 14 ohms

Now,

Since, We know that;

The current is the ratio of the potential difference and resistance.

That is,

⇒ I = V / R

⇒ V = I R

Thus, Substitute all the values, we get;

⇒ V = I R

⇒ V = 10 x 14

⇒ V = 140 Volts

Therefore, The voltage difference for an outlet will be 140 volts.

The length of a rectangle is 9 ft and width is 7 ft. Find its perimeter and area​

Answer:

Perimeter of rectangle = 32 feet Area of rectangle = 56 ft²

Step-by-step explanation:

Given :-

Length of rectangle = 9 feet Width of the rectangle = 7 feet

To Find :-

Perimeter and area

Solution :-

We know that,

Perimeter of rectangle = 2(L + W)

Substituting the values, we get:

↠ Perimeter = 2(9 + 7)

↠ Perimeter = 2(16)

↠ Perimeter = 32 feet

Now,

Area of rectangle = Length × Width

Substituting the values, we get:

↠ Area = 9 × 7

↠ Area = 56 ft²

Hence,

Perimeter of rectangle = 32 feet Area of rectangle = 56 ft²

Standard equation of a circle:

[tex](x-a)^2+(y-b)^2=r^2[/tex]

(where [tex](a,b)[/tex] is the centre of the circle, and [tex]r[/tex] is the radius)

If you expand this equation, you will see that the coefficient of [tex]y^2[/tex] is always one.

Therefore, [tex]p-3=1[/tex]

[tex]\implies p=1+3=4[/tex]

Additional information

To rewrite the given equation in the standard form:

[tex]\implies x^2+y^2-4x+6y-16=0[/tex]

[tex]\implies x^2-4x+y^2+6y=16[/tex]

[tex]\implies (x-2)^2-4+(y+3)^2-9=16[/tex]

[tex]\implies (x-2)^2+(y+3)^2=16+4+9[/tex]

[tex]\implies (x-2)^2+(y+3)^2=29[/tex]
