A fraction strip partitioned into seven parts with one part shaded. Another fraction strip partitioned into seven parts with one part shaded. An addition sign separates the two fraction strips. After second fraction strip there is an equal symbol and another fraction strip with seven parts with no parts shaded. Under the first fraction strip is the fraction one seventh. Under the second fraction strip is the fraction one seventh.

suppose 4:4:7 be 4x, 4x, 7x

or, 15x = 180°

or, X = 180/15

or, X = 12

therefore,

4x = 4x12= 48

4x= 4x12= 48

7x= 7x12= 84

so if you plus all of them you get 180

The three angles are 48, 48, and 84.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

The three angles in a triangle are 4x, 4x, and 7x.

Now,

4x + 4x + 7x = 180

15x = 180

x = 12

Now,

Substitute x = 12 in 4x, 4x, and 7x.

4x = 4 x 12 = 48

4x = 4 x 12 = 48

7x = 7 x 12 = 84

We can cross-check.

48 + 48 + 84 = 180

180 = 180

Thus,

The three angles are 48, 48, and 84.

Put 60 as x and get no of days .

Option C

Answer:

C. 75

Step-by-step explanation:

The scatter plot shows a positive correlation since the y-value increases as the x-value increases.

Given equation of the line of best fit:

y = 0.95x + 17.56

To estimate the number of days it takes for a 60-year-old house to be sold, input x = 60 into the given equation:

⇒ y = 0.95(60) + 17.56

⇒ y = 57 + 17.56

⇒ y = 74.56

⇒ y = 75 (nearest whole day)

Therefore, according to the line of best fit, an estimate of the number of days it will take for a 60-year-old house to be sold is 75 days.

Extrapolation

For this problem, we have used the line of best fit (regression line) to predict a value of that is outside the range of the original data. When using values of x outside the range to predict corresponding values of y, this is called extrapolation.  These predictions can be unreliable because there is no evidence that the relationship described by the regression line is true for all values of x.  Therefore, caution should be applied in these cases.

Answer:

11t - 4t= 7t

Step-by-step explanation:

11 - 4= 7

11t - 4t= 7t

t= 2

11t= 22

4t= 8

7t= 14

11t - 4t= 7t = 22 - 8= 14

Answer:

m∠B=22°

Step-by-step explanation:

All angles in a triangle add up to 180 degrees

Knowing this, we now understand:

∠A+∠B+∠C=180°

Let's substitute!

(120)+(x+16)+(x)=180

120+x+16+x=180

136+2x=180

2x=44

x=22°

Let's check to make sure!

Substitute:

120+(22)+16+(22)=180

180=180

Hope this helps! :D

Answer:

113

Step-by-step explanation:

180-22-45=113 umm just subtract

The measure of ∠x is 67 degrees.

A triangle is a three-sided polygon that consists of three edges and three vertices.

By angle sum property we find the measure  of ∠x

We have to find the adjacent angle of x to find value of x

22+45+X=180

67+X=180

Subtract 67 from both sides

X=180-67

X=113

We know that sum of adjacent angles is 180 degrees.

X+x=180

x=180-113

x= 67 degrees.

Hence,  the measure of ∠x is 67 degrees.

Answer:

Step-by-step explanation:

First, turn the word problem into an equation:

n(a number) was divided by 2

[tex]\frac{n}{2}[/tex]

followed by this quotient beying multiplied by 4

[tex]\frac{n}{2}[/tex]*4

the product was added to 9

[tex]\frac{n}{2}[/tex]*4+9

the total sum was 25

[tex]\frac{n}{2}[/tex]*4+9 = 25

use PEMDAS to solve the equation

subtract 9 on both sides

[tex]\frac{n}{2}[/tex]*4 = 16

cancel the 2 and the 4 using factorization

n*2 = 16

divide 2 on both sides

n = 8

The selling price of washing machine = Rs. 13500

Loss percent = 20%
