Step-by-step explanation:
1inch = 0.0833 ft.
Answer:
18 inches = 1.5ft
14 inches = 1.16ft
Step-by-step explanation:
First, you need to know how many inches are in a foot. Then you take what you have and divide it by that number. So it would be 18/12 or 14/12 and that would give you your answer

How to convert 12/25 to a decimal number.
Step-by-step explanation:
0.48 is the decimal form of 12/25
Answer:
0.48
Step-by-step explanation:
First you have to...
make the denominator to 100
25×4=100
multiply the numerator with that same number
12×4=48
So, it becomes...
48/100
And now you can convert it to a decimal number...
48/100= 0.48

la suma de las medidas de dos ángulos 80 grados y el complemento del primer ángulo es el doble de la medida del ángulo calcule la diferencia de las medidas de dichos ángulos
el complemento de un ángulo
Step-by-step explanation:
En este caso 70 ° y 20 ° son complementarios porque 70° + 20° = 90°.
Más ejemplos podrían ser 47° y 43°, ya que 47° + 43° = 90°, 30° y 60°, 45° y 45° , etc.
Dos ángulos son suplementarios si su suma forma un ángulo llano, es decir, 180°.
In the figure below, angles PQS and
TQR are congruent. Angle SQT is 15° larger
than angle PQS.
What is the measure of angle SQT?
Answe70
Step-by-step explanation:
The measure of the angle SQT will be 70°. The correct option is B.
What is geometry?One of the first areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.
Given that In the figure below, angles PQS and TQR are congruent. Angle SQT is 15° larger than angle PQS.
The measure of the angle SQT is,
2∠PQS + ∠SQT = 180
2∠PQS + ∠PQS + 15 = 180
3∠PQS = 165
∠PQS = 55°
The measure of the angle ∠SQT is,
∠SQT = 55 + 15
∠SQT = 70

You look up at a 62 m tall building and find that the angle of elevation from the ground to the top of the building is 51 degrees. How far away from the building's base are you?
Answer:
Step-by-step explanation:
horizontal distance = 62/tan(51°) ≅ 50.2 m
The distance between the building base to a standing point is 50.20 m if the angle of elevation from the ground to the top of the building is 51 degrees.
What is the trigonometric ratio?The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.
Trigonometry is a branch of mathematics that deals with the relationship between the sides and angles of a right-angle triangle.
It is given that:
You look up at a 62 m tall building and find that the angle of elevation from the ground to the top of the building is 51 degrees.
The angle = 51 degrees.
The height of the building = 62 m
Applying the tan ratio
tan51 = height of the building/distance between the building base to a standing point
tan51 = 62/x
x = 50.20 m
Thus, the distance between the building base to a standing point is 50.20 m if the angle of elevation from the ground to the top of the building is 51 degrees.

What is the slope below?
Answer:
-1.25
Step-by-step explanation:
-5/4
notice the two dotted points
in order to find slope, do RISE/RUN
in order for the two dotted points to meet, you must go UP 5 and ACROSS 4
rise = up
run = across
next, you need to solve the slope
do -5/4
-5/4 = -1.25
your answer is -1.25
Answer:
-1.25
Step-by-step explanation:
5/-4=-1.25
Suppose that the length of research papers is uniformly distributed from 12 to 25 pages. We survey a class in which 55 research papers were turned in to a professor. The 55 research papers are considered a random collection of all papers. We are interested in the average length of the research papers.
A.) Give the distribution of X. (round your standard deviation to two decimal places. X
∼ N (18.5, _____)
B.) Give the distribution of SumX. Round your standard deviation to two decimal places. SumX
∼ (1017.5, _____).
C). Calculate the probability that the professor will need to read a total of more than 1080 pages. _____
Answer:
A.) X ~ N(18.5, 3.75)
B.) SumX ~ N(1017.5,27.8).
C.) 0.0122 = 1.22% probability that the professor will need to read a total of more than 1080 pages.
Step-by-step explanation:
Uniform distribution:
A distribution is called uniform if each outcome has the same probability of happening.
The uniform distributon has two bounds, a and b.
The mean is given by:
[tex]M = \frac{a+b}{2}[/tex]
The standard deviation is given by:
[tex]S = \sqrt{\frac{(b-a)^2}{12}}[/tex]
Normal probability distribution
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
The uniform distribution can be approximated to the normal, using its mean and its standard deviation.
Sum of n terms of a normally distributed variable:
The mean of the sum will be:
[tex]\mu_{s} = n\mu[/tex]
The standard deviation of the sum will be:
[tex]\sigma_{s} = \sqrt{n}\sigma[/tex]
Suppose that the length of research papers is uniformly distributed from 12 to 25 pages.
This means that [tex]a = 12, b = 25[/tex]
We survey a class in which 55 research papers were turned in to a professor.
This means that [tex]n = 55[/tex]
A.) Give the distribution of X.
The mean has already been given, and the standard deviation is:
[tex]S = \sqrt{\frac{(25-12)^2}{12}} = 3.75[/tex]
So
X ~ N(18.5, 3.75)
B.) Give the distribution of SumX.
Sum of 55 papers, the standard deviation will be of:
[tex]\sigma_{s} = \sqrt{55}*3.75 = 27.8[/tex]
So
SumX ~ N(1017.5,27.8).
C). Calculate the probability that the professor will need to read a total of more than 1080 pages
This is 1 subtracted by the pvalue of Z when X = 1080. So
[tex]Z = \frac{X - \mu_{s}}{\sigma_{s}}[/tex]
[tex]Z = \frac{1080 - 1017.5}{27.8}[/tex]
[tex]Z = 2.25[/tex]
[tex]Z = 2.25[/tex] has a pvalue of 0.9878
1 - 0.9878 = 0.0122
0.0122 = 1.22% probability that the professor will need to read a total of more than 1080 pages.

Substitution 8th grade math homwork. 1 question
First person to get it answer gets reward
Answer: (5, 11)
Step-by-step explanation:
y = 2x + 1
x + y = 16
Substitute 2x + 1 for y in 'x + y = 16'
x + y = 16
x + (2x + 1) = 16
3x + 1 = 16
Subtract both sides by 1
3x = 15
Divide both sides by 3
x = 5
Now to find y
Since we know what x is, we can use one of the equations and substitute 5 for x. I'll use both to show that you get the same answer.
Second equation:
x + y = 16
5 + y = 16
Subtract both sides by 5
y = 11
First equation:
y = 2x + 1
y = 2(5) + 1
y = 10 + 1
y = 11
The solution would be (5, 11)
Answer:
(5, 11) point form
x=5,y=11 equation form

Question... factor 28+4x
Answer:
4(7 + x)
Step-by-step explanation:
28 + 4x
4 ⋅ 7 + 4x
4(7 + x)
good luck hope this helps :)
Find the greatest common factor for the terms involved in the polynomial.
In this case, the greatest common factor between 28 and 4 is 4.
So a 4 factors out of this polynomial.
That leaves us with each term divided by 4
inside a set of parentheses.
So we have 4(7 + x).
Now you can check your answer by distributing the 4 through
the parentheses and you will end up with your original polynomial.
