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

Good luck on your assignment :)

Answer:

Solution:

The selling price of washing machine = Rs. 13500

Loss percent = 20%

Let the cost price of the washing machine be Rs. x.

Loss = Loss% of C.P.

\Rightarrow⇒ Loss = 20% of Rs. x=\frac{20}{100}\times x=\frac{x}{5}x=

Answer:

Step-by-step explanation:

Please, share all given info.  What is the surface area of the given prism?

Let's call it A.  Then, looking at a cube, we see that there are 6 identical square faces of area (A/6).  The area of each face is therefore F = √(A/6).  The edge length is the square root of this F:

edge length = √ (√(A/6) ).  Alternatively, edge length = (A/6)^(1/4)

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:

the answer is the fourth one

Step-by-step explanation:

Priya was invited to the party meaning she read 25 or more books

≥ - greater than or equal to

The correct inequality that represents Priya's number of books is x ≥ 25

From the question, we understand that:

Only those who read at least 25 books are invited

At least in inequality means "greater than or equal to"

This means that students who read the number of books greater than or equal to 25 were invited

Priya's number of books is x

Hence, the correct inequality that represents Priya's number of books is x ≥ 25

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

Answer:

6, 4, 1.5, 0

Step-by-step explanation:

6 times 2 = 12 and 3 times 6 = 18
12+18=30

4x3=12 and 9x2=18
12+18=30

1.5x2=3 and 9x3=27
27+3=30

0x3=0 and 15x2=30

150% can be written as a decimal as 1.5

150% can be written as a fraction of 3/2.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

150%

This can be written as:

Fraction:

= 150%

= 150/100

= 15/10

= 3/2

Decimal:

= 150%

= 150/100

= 15/10

= 1.5

Thus,

150% = 3/2

150% = 1.5

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.
