What is the measure of ∠P ?
with explanation pls
Answer:
80°
Step-by-step explanation:
we know angle R and angle Q are equal cause of the dashes
so
2x+30=6x-10
and then solve
30=4x-10
40=4x
10°=x
since they're equal just plug in X for one
2(10)+30= angle r
50° = angle r
we have two 50° angles and we know every triangle is 180°
so create the formula
angle r + angle q + angle p =180°
fill it in
50° + 50° + p = 180°
so angle p= 80°

Find the circumference and area of a circle with diameter 4 cm.
HELP ASAP PLS
Step-by-step explanation:
the formulas can be easily found on the internet.
remember, the diameter of a circle is 2 times the radius.
so, the radius of our circle here is 4/2 = 2 cm.
circumference :
2×pi×r = 2×3.14×2 = 12.56 cm
area :
pi×r² = 3.14×2² = 3.14×4 = 12.56 cm²
hey, your teacher gave you the circle, where the circumference and the area have the same quantity ! funny !
so, make double sure you use the correct unit dimensions (remember, a distance has only one dimension, an area has 2 dimensions, and a volume has 3 dimensions).

A moving-van rental company uses the polynomial 130 + 0. 75(m – 200) to calculate the rental charges if a customer drives a van more than 200 miles in one day. In the polynomial, m is the total number of miles that the customer drove the van during the day. Use the Distributive Property to write an equivalent expression for the total cost of renting the van and driving it more than 200 miles in one day
Answer:
im not sure but i think this is the answer
Step-by-step explanation:
I think it would be 130 + 0.75m
Which simplified could be 130.75m Hope it helps! :)

The slope is 0.75
Substitute m for 0 ( [tex]0.75(-200) + 130[/tex])
Evaluate the equation ( [tex]0.75(-200) + 130[/tex]) = -20, this is the y-intercept

A 2-column table with 6 rows. the first column is labeled week with entries 1, 2, 4, 6, 8, 10. the second column is labeled miles run with entries 5, 8, 13, 15, 19, 20. rita is starting a running program. the table shows the total number of miles she runs in different weeks. what is the equation of the line of best fit for the data? state each number to the thousandths place. y ≈ x
The line of best fit for the data of week and the corresponding miles run is evaluated to be: y = 4.699 + 1.671x
How does linear regression works?Firstly, there is a data set. Then, we try to fit a line which will tell about the linear trend. This line is made using the least squares method.
The following data for the Week and miles run variables are provided to construct linear regression model:
Week miles run
1 5
2 8
4 13
6 15
8 19
10 20
The independent variable is Week(represented by x), and the dependent variable is miles run(represented by y). In order to compute the regression coefficients, the following table needs to be used:
Let week = x, and miles run = y, then we get this table:
x y xy [tex]x^2[/tex] [tex]y^2[/tex]
----------------------------------------------------

10 20 200 100 400
-----------------------------------------------------
Sum = 31 80 515 221 1244
Based on the above table, the following is calculated:
[tex]\bar X = \frac{1}{n} \sum_{i=1}^{n} X_i = \frac{ 31}{ 6} \approx 5.167[/tex]
[tex]\bar Y = \frac{1}{n} \sum_{i=1}^{n} Y_i = \frac{ 80}{ 6} \approx 13.33[/tex]
[tex]\large SS_{XX} = \sum_{i=1}^{n} X_i^2 - \displaystyle\frac{1}{n}\left(\sum_{i=1}^{n} X_i\right)^2 = 221 - 31^2/6 \approx 60.833[/tex]
[tex]\large SS_{YY} = \sum_{i=1}^{n} Y_i^2 - \displaystyle\frac{1}{n}\left(\sum_{i=1}^{n} Y_i\right)^2 = 1244 - 80^2/6 \approx 177.33[/tex]
[tex]\large SS_{XY} = \sum_{i=1}^{n} X_i Y_i - \displaystyle\frac{1}{n}\left(\sum_{i=1}^{n} X_i\right) \left(\sum_{i=1}^{n} Y_i\right) = 515 - 31 \times 80/6 \approx 101.67[/tex]
Therefore, based on the above calculations, the regression coefficients (the slope m, and the y-intercept n) are obtained as follows:
[tex]m = \frac{SS_{XY}}{SS_{XX}} \approx \frac{ 101.67}{ 60.833} \approx 1.6712[/tex]
[tex]n = \bar Y - \bar X \cdot m = 13.33- 5.167 \times 1.6712 = 4.6986[/tex]
Therefore, we find that the regression equation is:
miles run = 4.6986 + 1.6712 Week
y = 4.6986 + 1.6712x (approximately)
To the thousandths place, it becomes:
y = 4.699 + 1.671x
Therefore, based on the information provided above, the following scatter plot and regression plot are obtained as the image attached below.
Thus, the line of best fit for the data of week and the corresponding miles run is evaluated to be: y = 4.699 + 1.671x

A survey of customers at a restaurant revealed that 7 out of 10 customers preferred the restaurants new spaghetti sauce. Which graph shows a relationship between y, the number of customers who preferred the new spaghetti sauce, and x, the total of customers?
The graph that shows the proportional relationship y = 0.7x is Graph A.
What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
In this problem, 7 out of 10 customers preferred the restaurants new spaghetti sauce, hence the constant is given by:
k = 7/10 = 0.7.
And the equation is:
y = 0.7x.
When x = 0, y = 0, which already eliminates graphs C and D. When x = 10, y = 7, which means that Graph A is the answer to this question.

A. Function A has a vertical asymptote at x = 1.
Function B has a vertical asymptote at x = 0.
B. Function A has a vertical asymptote at x = 1.
Function B has a vertical asymptote at x=−3.
C. Function A has a vertical asymptote at x=−1.
Function B has a vertical asymptote at x=−3.
D. Both functions have the same vertical asymptote.
Answer:
B. Function A has a vertical asymptote at x = 1.
Function B has a vertical asymptote at x=−3.
Step-by-step explanation:
You can see from the diagram that the asymptope is x = -3, but to find the asymtope for the function make denominator equal to 0 and solve because the denominator can never equal 0, (you divide a number by 0, which is mathematically impossible) therefore the function will never reach that line.

No answer. The question is not correct. 2x-6 cannot be equal to 2x+4
Step-by-step explanation:
2(x-3) = 2x+4
2x-6 = 2x+4
This can't be true. 2x-6 cannot be equal to 2x+4:
Subtract 2x from both sides and we are left with -6 = 4: FALSE
Answer:
no solutionStep-by-step explanation:
Taking the LHS and distributing
2(x - 3)2(x) - 2(3)2x - 6Equating to the RHS
2x - 6 = 2x + 4On inputting any value for x, this equation will not be correct.

A solid shape is made by joining two cones.
Each cone has the same radius.
One cone has
slant height = 2 × radius
The other cone has slant height = 3 × radius
The total surface area of the shape is 135. 21 cm²
Curved surface area of a cone = tırl where r is the radius and / is the slant height
Work out the radius.
The surface area of the solid shape is the amount of space on it
The radius of the two cones is 2.93 cm
How to determine the radius?The given parameters are:
Cone 1: slant height, l = 2rCone 2: slant height, L = 3rSurface area = 135. 21 cm²The surface area of the shape is calculated using:
T = πr(L + l)
So, we have:
135.21 = πr(2r + 3r)
Evaluate
135.21 = 5πr²
Divide both sides by 5π
r² = 135.21/5π
Evaluate the quotient
r² = 8.61
Take the square root of both sides
r = 2.93
Hence, the radius of the cones is 2.93 cm

If the average annual interest rate is 17.11%, how many months will it take the average American family to pay off their debt of $7,942 if they make a minimum payment of $175 each month and no additional purchases are made? months.
The payoff period will be 73.56 months if the average annual interest rate is 17.11%, how many months will it take the average American family to pay off their debt of $7,942
What is compound interest?It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]
Where A = Final amount
P = Principal amount
r = annual rate of interest
n = how many times interest is compounded per year
t = How long the money is deposited or borrowed (in years)
We have:
Loan amount = $7942, Monthy pay = $175, Interest rate = 17.11%
After calculating from the payment formula:
The payoff = 6.13 years = 73.56 months
Thus, the payoff period will be 73.56 months if the average annual interest rate is 17.11%, how many months will it take the average American family to pay off their debt of $7,942
