The ratio of the measures of the sides of a triangle is 2:8:9. If the perimeter of the triangleis 76 inches, find the length of each side. for geometry

Answers

Answer:

The lenghts of the sides are: 8 inches, 32 inches, 36 inches.

Step-by-step explanation:

Perimeter of a triangle:

The perimeter of a triangle is given by the sum of it's sides dimensions.

The ratio of the measures of the sides of a triangle is 2:8:9.

This means that their measures are:

The first measure is x

The second measure is of: [tex]\frac{8x}{2} = 4x[/tex]

The third measure is of [tex]\frac{9x}{2}[/tex]

So the perimeter will be of:

[tex]x + 4x + \frac{9x}{2} = 76[/tex]

[tex]5x + \frac{9x}{2} = 76[/tex]

[tex]\frac{10x}{2} + \frac{9x}{2} = 76[/tex]

[tex]\frac{19x}{2} = 76[/tex]

[tex]19x = 76*2[/tex]

Simplifying by 19

[tex]x = 4*2 = 8[/tex].

So, dimensions of:

[tex]8, 4*8 = 32, \frac{9*8}{2} = 36[/tex]

The lenghts of the sides are: 8 inches, 32 inches, 36 inches.

1. X=35 degrees obtuse

2 x=25 degrees right

Step-by-step explanation:

Background info:

The measures of the angels of every triangle is 180 degrees

So x equals 180 minus the other angles combined

1. X=180-(40+105)

X=180-145

X=35 degrees

2.

x=180-(90+65)

x=180-155

x=25 degrees

A medical supplier sells gauze in large and small rectangular sheets. A large sheet has a length of 9 inches and an area of 45 square inches. A small sheet has a length of 4 inches and a width of 3 inches. Are the sheets similar?

Answers

Answer:

Step-by-step explanation:

Large sheet:

 Length = 9 inches

 Width of large sheet = area ÷ length = 5 inches

 ratio of length to width = 9:5

Small sheet:

 Length = 4 inches

 Width = 3 inches

 ratio of length to width = 4:3

9:5 ≠ 4:3

The sheets are not similar

The large sheet and small sheet are not similar because they have different dimensions.

What is the area of a rectangle ?

Area of rectangle is the region occupied by a rectangle within its four sides or boundaries.

It is given that large sheet has a length of 9 inches and an area of 45 square inches whereas the small sheet has length of 4 inches and a width of 3 inches.

Let's find out the area of small sheet which will be :

A = L × B

A = 4 × 3

A = 12 inches²

Whereas , in case of large sheet the area is 45 inches². So , the area of both sheets are not similar.

Let's check if dimensions are same.

Width of large sheet will be :

A = L × B

45 = 9 × B

or

B = 5 inches

So , dimensions are also not equal.

Therefore , the large sheet and small sheet are not similar because they have different dimensions.

The number of siblings an individual has varies from student to student. The distribution of the number of siblings is strongly skewed to the right. The central limit theorem says that:________

(a) as we look at more and more students, their mean number of siblings gets ever closer to the mean u for all students.

(b) the mean number of siblings for any number of students has a distribution of the same shape (strongly skewed) as the distribution for individual students.

(c) the mean number of siblings for any number of students has a distribution that is close to Normal.

(d) the mean number of siblings for a large number of students has a distribution of the same shape (strongly skewed) as the distribution for individual students.

(e) the mean number of siblings for a large number of students has a distribution that is close to Normal.

Answers

Answer:

(e) the mean number of siblings for a large number of students has a distribution that is close to Normal.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

By the Central Limit Theorem

The sampling distributions with a large number of students(at least 30) will be approximately normal, so the correct answer is given by option e.

2x+3=11?

Answers

Answer:

2x+3=11

2x=11-3

x=8/2

x=4........

Answer: [tex]x = 4[/tex]

Step-by-step explanation:

Okay, so we start with our equation.

[tex]2x + 3 = 11[/tex].

Then we need to get x alone. To do that we subtract the 3 on the side with the x.

But what we do to one side, we do to the other. So we subtract 3 from the 11 as well

2x + 3 = 11    

      -3    -3

2x = 8

Then we divide by 2 on both sides to get X.

[tex]\frac{2x}{2} =\frac{8}{2}[/tex]

[tex]\frac{2x}{2} = x[/tex]

[tex]\frac{8}{2} = 4[/tex]

[tex]x = 4[/tex].
