In the number 4,444.444, how does the 4 in the tenths place compare to the 4 in the place to its right?

Answer:

Step-by-step explanation:

The formulas for the areas of a rectangle and a parallelogram are actually the same; both involve length and width.  

It may be easier to understand this if you draw a rectangle of width w with a drawing of a parallelogram of width underneath.  The parallelogram's ends appear slanted; they are neither vertical nor horizontal.  However, so long as you measure the length of the rectangle horizontally, all measurements are equal to each other as well as equal to the length of the rectangle.

Hence the calculated areas will be one and the same.

Area formula of a rectangle to find the area formula of parallelogram, the length of the rectangle should be used as the height of the parallelogram.

Area of rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,

[tex]A=a\times b[/tex]

Here, [tex]a[/tex] is the length rectangle and [tex]b[/tex] is the width of the rectangle.

Given information-

The area formula of parallelogram has to find using the area formula of rectangle.

Parallelogram is a closed shaped quadrilateral polygon in which opposite sides is equal and parallel and opposite angles are equal.

The shape of the parallelogram is attached below.

The area of the rectangle is the base time height. It can be given as,

[tex]A_r=l\times h[/tex]

In case of a parallelogram the height of the parallelogram is not equal to the side of it.

The area of the parallelogram is still given as the area of rectangle which is base time height, with new height.

Thus for the attached figure of parallelogram the area of it can be given as,

[tex]A_p=l\times h[/tex]

Hence, The area formula of a rectangle to find the area formula of a parallelogram, the length of the rectangle should be used as the height of the parallelogram.

Answer:

∠1

Step-by-step explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠1 is an exterior angle and ∠' s 2 and 3 are the opposite interior angles.

Hence

∠2 + ∠3 = ∠1

The measure of angle 1 is equal to the sum of the measures of angles 2 and 3.

The sum of the measures of angles 2 and 3 is equal to the measure of exterior angle B, which is angle 1.

This relationship is described by the exterior angle theorem, which states that the measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.

So, we have:

[tex]\[ \text{Angle 1} = \text{Angle 2} + \text{Angle 3} \][/tex]

Therefore, the measure of angle 1 is equal to the sum of the measures of angles 2 and 3.

The probable question may be:

In the given figure, the sum of the measures of angles 2 and 3 is equal to the measure of which angle?

Answer: OPTION C

Step-by-step explanation:

To solve the exercise you must descompose the number 648 into its prime factors, as you can see below:

[tex]648=2*2*2*3*3*3*3[/tex]

You can rewrite the above as following:

[tex]648=2^3*3^4[/tex]

Then:

[tex]\sqrt{648}=\sqrt{2^3*3^4}[/tex]

Therefore, as you can see, the value of  a and b are the following:

[tex]a=3,b=4[/tex]

Answer:

The correct answer option is C. a=3, b=4.

Step-by-step explanation:

We are given the following expression and we need to determine whether which of the values of [tex]a[/tex] and [tex]b[/tex] should be used to make the equation true:

[tex] \sqrt { 648 } = \sqrt { 2 ^ a \times 3 ^ b } [/tex]

A. a=3, b=2:

[tex] \sqrt { 2 ^ 3 \times 3 ^ 2 } = \sqrt { 72 } [/tex]

B.  a=2, b=3:

[tex] \sqrt { 2 ^ 2 \times 3 ^ 3 } = \sqrt { 108 } [/tex]

C. a=3, b=4 :

[tex] \sqrt { 2 ^ 3 \times 3 ^ 4 } = \sqrt { 648 } [/tex]

D. a=4, b=3:

[tex] \sqrt { 2 ^ 4 \times 3 ^ 3 } = \sqrt { 432 } [/tex]

Therefore, the correct answer option is C. a=3, b=4.

Answer:

Part 7) Option C. The approximate perimeter of the patio is [tex]54\ ft[/tex]

Part 8) Option G. [tex]3\ floats[/tex]

Part 9) [tex]150.72\ minutes[/tex]

Step-by-step explanation:

Part 7) we know that

The perimeter of the figure is equal to the circumference of the larger half circle plus the circumference of the smaller half circle plus two times the length of 8 ft

step 1

Find the circumference of the larger half circle

The circumference of the larger half circle is

[tex]C=\pi r[/tex]

we have

[tex]r=8+2=10\ ft[/tex]

substitute

[tex]C=\pi(10)[/tex]

[tex]C=10\pi\ ft[/tex]

step 2

Find the circumference of the smaller half circle

The circumference of the smaller half circle is

[tex]C=\pi r[/tex]

we have

[tex]r=2\ ft[/tex]

substitute

[tex]C=\pi(2)[/tex]

[tex]C=2\pi\ ft[/tex]

step 3

Find the perimeter of the figure

[tex]10\pi\ ft+2\pi\ ft+2(8)\ ft=(12\pi+16)\ ft[/tex]

assume [tex]\pi=3.14[/tex]

so

[tex](12(3.14)+16)=53.68=54\ ft[/tex]

Part 8) we know tat

The area of a circle is equal to

[tex]A=\pi r^{2}[/tex]

we have

[tex]A=28.26\ ft^{2}[/tex]

assume [tex]\pi=3.14[/tex]

substitute the values and solve for r

[tex]28.26=(3.14)r^{2}[/tex]

[tex]r^{2}=28.26/(3.14)[/tex]

[tex]r^{2}=9[/tex]

[tex]r=3\ ft[/tex]

Find the diameter D

[tex]D=2r=2(3)=6\ ft[/tex]

Divide the width of the pool by the diameter of the floats

so

[tex]\frac{18}{6}=3\ floats[/tex]

Part 9)

step 1

Find the circumference of one coaster

The circumference of circle is

[tex]C=2\pi r[/tex]

we have

[tex]r=1.5\ in[/tex]

assume [tex]\pi=3.14[/tex]

substitute

[tex]C=2(3.14)(1.5)=9.42\ in[/tex]

step 2

Find the circumference of 48 coasters

so

[tex]48(9.42)=452.16\ in[/tex]

step 3

we know that

The laser cut woods at the rate of 3 inches per minute

By proportion find how many minutes will it take to cut out 48 coasters

[tex]\frac{3}{1}\frac{inches}{minute} =\frac{452.16}{x}\frac{inches}{minutes}\\ \\x=452.16/3\\ \\x=150.72\ minutes[/tex]

Answer:

[tex]\begin{array}{c|c}x&y\\-2&13\\-1&9\\0&5\\1&1\\2&-3\end{array}[/tex]

Step-by-step explanation:

Put x = -2, x = -1, ... , x = 2 to the equation of the function y = -4x + 5 and calculate the values of y:

for x = -2

y = -4(-2) + 5 = 8 + 5 = 13

for x = -1

y = -4(-1) + 5 = 4 + 5 = 9

for x = 0

y = -4(0) + 5 = 0 + 5 = 5

for x = 1

y = -4(1) + 5 = -4 + 5 = 1

for x = 2

y = -4(2) + 5 = -8 + 5 = -3

Just put the values given for x in the equation to find y

-4(-2)+5=13

-4(-1)+5=9

-4(0)+5=5

-4(1)+5=1

-4(2)+5=-3

Answer: Step 3: [tex]3x>3[/tex] (Subtraction).

Step-by-step explanation:

1- Given the inequality shown in the problem, Zareen should solve it as following:

2-Subtract 4x from both sides:

[tex]7x + 5-4x > 4x + 2 -4x\\3x+5>2[/tex]

(Zareen did this step correctly)

3- Subtract 5 from both sides:

[tex]3x + 5-5 > 2-5\\3x>-3[/tex]

(As you can see, Zareen made a mistake in Step 3, because the subtraction is actually  [tex]2-5=-3[/tex])

4- Divide both sides by 3, then:

[tex]\frac{3x}{3}>\frac{-3}{3}\\\\x>-1[/tex]

Zareen's mistake occurred in Step 2, where she incorrectly subtracted terms that did not simplify the inequality properly. She should have subtracted 4x from both sides and then divided by 3 to isolate x and solve correctly, which would have given x > -1.

Zareen made her mistake in Step 2 of solving the inequality

7x + 5 > 4x + 2.

In this step, she should have subtracted 4x from both sides of the inequality to isolate the variable term (x) on one side. This would have resulted in

3x + 5 > 2,

which she correctly simplified to

3x > -3

after subtracting 5 from both sides. Following the order of operations to the end, she would then divide both sides by 3 to find x > -1. However, the provided solution incorrectly states that the second step of just subtracting 3x resulted in the term 5 > 2, which is not relevant to the inequality manipulation and does not follow the correct algebraic steps to solve the inequality. The correct sequence would respect the operations to eliminate terms and simplify the algebra.

Step-by-step explanation:

The process is really easy, all you have to do is substitute the numbers of the ordered pairs into the equations.

So like for A. (-5,8)

Putting this into the equation would look like this,

10 * -5 + 2 * 8 The -5 being substituted for the x and the 8 for the y.

This equation equals to -34, not 64.

3 * -5 - 4 * 8 = -47

not equal to -36, so A is eliminated.

For B. (4,12)

10 * 4 + 2 * 12 = 64

3* 4 - 4 * 12 = -36

These equal to both of the given equations.

For C. (2, 10)

10 * 2 + 2 * 10= 40

3 * 2 - 4 * 10 = -34

These are not equal to the given answers of these equations, C is eliminated.

And D. (-3,11)

10 * -3 + 2 * 11 = -8

3 * -3 - 4 * 11 = -53

These are not equal to the given answers of these equations, D is eliminated.

So the only pair that have made both equations true is B.(4,12)

step 1

Find the value of x

Let

O ----> the center of the circle

we know that

Triangle BOC≅Triangle COD

[tex]m\angle BOC=arc\ BC[/tex] ----> by central angle

[tex]m\angle COD=arc\ CD[/tex] ----> by central angle

[tex]m\angle BOC=m\angle COD[/tex]

therefore

[tex]arc\ BC=arc\ CD[/tex]

substitute the given values

[tex](9x-53)^o=(2x+45)^o[/tex]

solve for x

[tex]9x-2x=45+53\\7x=98\\x=14[/tex]

step 2

Find the measure of angle BAD

we know that

The inscribed angle is half that of the arc it comprises.

so

[tex]m\angle BAD=\frac{1}{2} [arc\ BC+arc\ CD][/tex]

[tex]arc\ BC=9(14)-53=73^o[/tex]

[tex]arc\ CD=2(14)+45=73^o[/tex]

substitute

[tex]m\angle BAD=\frac{1}{2} [73^o+73^o]=73^o[/tex]

The measure of mBAD is 73⁰

Given the following expression

mBC = (9x-53) and mCD = (2x + 45)

From the given diagram, both arcs are equal, hence

9x - 53 = 2x +45

7x = 98

x = 14

Get the measure of arc BC

arcBC = 9x - 53

arcBC = 9(14)-53

arcBC = 73 degrees

The measure of mBAD = 1/2(73+73) = 73 degrees

Hence the measure of mBAD is 73⁰
