How many inches are in 4 1/2 yards of fabric?

Answers

Answer: 162 inches

Step-by-step explanation: 4 yards are 144 inches and 1 yard alone is 36 when you divide it by half it’s 18. (144+18=162)

To convert [tex]4 \dfrac{1}{2}[/tex]  yards of fabric to inches, multiply by 36.

Therefore, there are 162 inches in [tex]4 \dfrac{1}{2}[/tex]  yards.

For the measurement, we know

1 yard = 36 inches

The given measurement is: [tex]4 \dfrac{1}{2}[/tex]  yards

Convert it into an improper fraction,

[tex]4\dfrac{1}{2} = \dfrac{4 \times 2 + 1}{2} \\\\ = \dfrac{9}{2}[/tex]

Thus, [tex]4 \dfrac{1}{2}[/tex]  yards can be written as [tex]\dfrac{9}{2}[/tex]  yards.

Since 1 yard = 36 inches

Therefore,

(9/2) yards = (9/2)x36 inches

= 9 x 18 inches

= 162 inches

Hence,

The measurement  [tex]4 \dfrac{1}{2}[/tex]  yards are equivalent to 162 inches.

What are coordinates in a graph?

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

y + 4 = 25 ( x + 3)

Some coordinates on the graph are:

When x = 0,

y + 4 = 175

y = 175 - 4

y = 171

When x = 1,

y + 4 = 25 (1 + 3)

y = 100 - 4

y = 96

Now,

What is the density of the glass in 2.5 g/cm in kg/m

Answers

We are given:                                                                                                        

Density of glass in g/cm³ = 2.5

Finding the density in kg/m³:                                                                              

In converting 2.5 g/cm³ to kg/m³, we will first convert the g to kg

Converting the g to kg:

2.5 g/cm³ * 1

Since 1kg = 1000g, 1kg/1000g = 1

2.5 g/cm³ * 1kg / 1000g

the g in the numerator and the denominator will cancel out and we will get:

2.5 kg / 1000 cm³

Converting the cm³ to m³:

We know that 1 m³ = 10⁶ cm³

So, 10⁶ cm³ / 1 m³ = 1

Multiplying the density by 1

2.5 kg / 10³ cm³   *   1

2.5 kg / 10³ cm³   *   10⁶ cm³ / 1 m³

the cm³ in the numerator and the denominator will cancel out

2.5 * 10⁶ kg / 10³ m³

2.5 * 10³ * 10³ kg / 10³ m³

2.5 * 10³ kg / m³

2500 kg/m³

Congruent triangle

Answers

Answer:

x = 3

Step-by-step explanation:

exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles

97 + x = 64 + 27

x = 97 - 64 - 27 = 6

Answer: x=-6

you know that the interior angles of a triangle equal 180°. so lets find the remaining angle measure

64 + 27 = 91

180 - 91 = 89

so 89 is the third interior angle of the triangle. now let's find the exterior angle.

you know that the extended angle is supplementary; which means it will equal 180° as well. so lets add the third interior angle we just found and let's add it to the unknown expression:

89 + 97 + x = 180

186 + x = 180

-186        -186

x = -6

now it might seem wrong because x is negative and it feels like it should be positive. but let's check our answer.

64+27+89 does equal 180

and 97+(-6)+89 does equal 180

Find the radius of a circle given that a central angle of measure pi/4 intercepts an arc of length 1.5in

Answers

Given:

Central angle = [tex]\dfrac{\pi}{4}[/tex]

Arc length = 1.5 in

To find:

The radius of the circle.

Solution:

We know that the formula for arc length is

[tex]s=r\theta[/tex]

Where r is radius and [tex]\theta [/tex] is the central angle in radian.

Substitute the given values in the above formula.

[tex]1.5=r\times \dfrac{\pi}{4}[/tex]

[tex]6=\pi r[/tex]

[tex]\dfrac{6}{\pi}=r[/tex]

[tex]\dfrac{6}{3.14}=r[/tex]

On further simplifiation, we get

[tex]r=1.910828[/tex]

[tex]r\approx 1.91[/tex]

Therefore, the radius of the circle is 1.91 in.

Gordon BrowneOn the 1st of December the Queen felt anxious and depressed. Her husband grew worse and could not take food without considerable difficulty, and this made him very weak and irritable.The physicians in attendance were now obliged to tell her that the illness was low fever, but that the patient himself was not to know of this. The Ministers became alarmed at his state, and when the news of his illness became public there was the greatest and most universal anxiety for news.In spite of slight improvements from time to time, the Prince showed no power of fighting the disease, and on the evening of the 14th December he passed gently away.It is no exaggeration to say that the death of the Queen's beloved husband saddened every home in the land; it was a sorrow felt equally by the highest and the lowest. He died in the fulness of his manhood, leaving her whom he had loved and guarded so tenderly to reign in lonely splendour.Passage 2: Queen Victoria by Giles Lytton StracheyOn the morning of December 14, Albert, just as she had expected, seemed to be better; perhaps the crisis was over. But in the course of the day there was a serious relapse. Then at last she allowed herself to see that she was standing on the edge of an appalling gulf. The whole family was summoned, and, one after another, the children took a silent farewell of their father. "It was a terrible moment," Victoria wrote in her diary, "but, thank God! I was able to command myself, and to be perfectly calm, and remained sitting by his side." He murmured something, but she could not hear what it was; she thought he was speaking in French. Then all at once he began to arrange his hair, "just as he used to do when well and he was dressing." "Es kleines Frauchen," she whispered to him; and he seemed to understand. For a moment, towards the evening, she went into another room, but was immediately called back; she saw at a glance that a ghastly change had taken place.
