Step-by-step explanation:
A student is finding the measures of the angles in a triangle that have the ratio 4:4:7. Find the mistake and correct it.
4x+4x+7x15xx===18018012
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.
What is an equation?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.

A triangle labeled ABC with angle A as one hundred twenty degrees, angle B as X degrees and angle C as parenthesis X plus sixteen parenthesis degrees
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

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)
One number was divided by 2, followed by this quotient being multiplied by 4. next, the product was added to 9. the total sum was 25, so what was the first divisor?
please show work and answer
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
Choose the correct inequality.
The library is having a party for any student who read at least 25 books over the summer. Priya read x books and was invited to the party.
copied for free from openupresources.org
Select one:
x < 25
x > 25
x ≤ 25
x ≥ 25
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
How to determine the inequality?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:
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=

Therefore, S.P. = C.P. - Loss

The scatter plot below shows the relationship between the age of a house and the number of days it takes for the house to be sold after being listed for sale.
The equation y = 0.95x + 17.56 describes the line of best fit for the scatter plot. Based on the equation, which value is most likely the number of days it takes for a 60-year-old house to be sold after being listed for sale?
A. 45
B. 70
C. 75
D. 83
Put 60 as x and get no of days .
y=0.95x+17.56y=0.95(60)+17.56y=57+17.56y=74.56y=75daysOption 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.

What is the measure of ∠x , in degrees, in the figure shown?
Answer:
113
Step-by-step explanation:
180-22-45=113 umm just subtract
The measure of ∠x is 67 degrees.
What is Triangle?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:
The theoretical probability is that it will be Heads Heads 25% of the time. However, the experimental probability is 10%.
Step-by-step explanation:
The main difference between experimental and theoretical probability is that experimental probability is based on the actual results of an experiment. In contrast, the theoretical probability is based on possible outcomes based on assumptions.
