Step-by-step explanation:
The solution is, the value of x is approximately 116.5 meters.
What is trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
here, we have,
We are given the following information
From this picture, we want to find the vaule of x. To so, we will use the sine law. to solve this problem.
The sine law relates the sine of the angles of the triangle and the length of the opposite sides of the triangle. If we have a triangle of the form
Then,the sine law states that
sinA/a =sinB/b =sinC/c
Which is equivalent to
a/sinA = b/sinB = c/sinC
In our case, we are given the measure of angles A and B and missing the measure of angle C. Also, we are given the measure of side c. If we apply the sine law to the given triangle we have
x/ sin 35 = 200/ sin 80
So, first we need to identify the value of C. To do so, we will use the following fact:
The sum of the inner angles of a triangle is 180°.
Then, we have the following equation
65 +35 +C = 180
If we operate on the left side, we get
100+C = 180
So, by subtracting 100 from both sides, we get
C= 80
So, if we replace the value of C in the equation we had, we get
x/ sin 35 = 200/ sin 80
If we multiply both sides by sin(35) we get
x = 200* sin 35/ sin80
so, using a calculator we get
x = 116.5
so the value of x is approximately 116.5 meters

The equation of the least squares regression line which is most closely matches the data set is yˆ=−10.1x+118.8
What is linear regression?Linear regression is a type of regression which is used to model the data having linear relationship between the variables. The regression line can be given as,
[tex]\hat y=bX+a[/tex]
The data given in the problem is,
x 2 4 6 8 10y 100 83 50 35 23Mean of x and y values,
[tex]\mu_x=\dfrac{2 +4 +6 +8 +10}{5}=6\\\mu_y=\dfrac{100 +83 +50 +35 +23}{5}=58.2[/tex]
Here, in this data points, the sum of the squares is 40 and sum of the products is -404. The value of b is,
[tex]b=\dfrac{-404}{40}\\b=-10.1[/tex]
The value of a is,
[tex]a=58.2-(10.1\times6)\\a=118.8[/tex]
Put the values in the above equation,
[tex]\hat y=-10.1X+118.8a[/tex]
Thus, the equation of the least squares regression line which is most closely matches the data set is yˆ=−10.1x+118.8

Rachel runs 4 miles in 23 minutes. How many miles does she run per minute?
Answers
Answer:
To calculate how many total miles Rachel runs per minute, setting up a unit rate, that is a rate with a denominator of 1, would be helpful.
Step-by-step explanation:
Use the current problem to determine a rate.
23 minutes/4 miles
Now, set up a unit rate.
1 minute/x miles = 23 minutes/4 miles
To solve for x, we can use simple division strategies. We divide 23 by 23 to receive 1 minute. Likewise, dividing the current milage by 23 would wield the correct unit rate. To do this, divide 4 by 23.
4/23 = 0.1739130434782609
Finally, simplify your answer to receive 0.17.
Therefore, Rachel runs ~0.17 miles per minute. (Note that this answer is only a rounded answer of her actual milage per minute)

21.75 or [tex]21\frac{3}{4}[/tex]
Step-by-step explanation:
You have to convert from a mixed number to a decimal. You can follow the following steps: To do this:
1.) You must divide the fraction's numerator by the denominator.
2.) You must now add the quotient obtained to the part of the Whole number.
you will get:
[tex]{\large\boxed{\fcolorbox{7}{\frac{1}{4}=7+0.25=7.25 }}[/tex]
The scale of the image that maps "Figure a" to "Figure b" is:

3.) You have to multiply by 7.25 the length of the corresponding side of "Figure A" in order to find the value "x."

Answer:
9p + 6q
Step-by-step explanation:
Rewrite each expression
Combine like terms
13p - 4p + 6q
_____________________
When we have like terms, we can only add the ones that have the same symbols as endings, such as variables, exponents, etc. Therefore :
Add "p" values together :
13p - 4p
9p.
Now rewrite the expression, we cannot combine like terms with "p" and "q" because they are not the same variable :
9p + 6q
