Answer:
aef = fed = 51 degrees,
and the full angle aed = 102 degrees
Step-by-step explanation:
If ef bisects the angle aed, then the two angles it defines: aef and fed, must measure the same.
Therefore we can asume that aef = fed which numerically means:
4 x + 3 = 7 x - 33
so we solve for x:
33 + 3 = 7 x - 4 x
36 = 3 x
x = 36/3
x = 12 degrees
That means that the half angle aef measures:
aef = 4 x + 3 = 4 (12) + 3 = 48 + 3 = 51 degrees
Then we have that aef = fed = 51 degrees,
and the full angle aed = 51 + 51 = 102 degrees

I NEED HELP PLEASE! The approach ramp used by a daredevil motorcyclist for flying over a pit of venomous snakes has a rise of 52 feet for every 80 feet in horizontal distance. Find the grade of the ramp. Round to the nearest whole percent.
Answer:
65%
Step-by-step explanation:
The formula for the grade of the ramp = Rise of the ramp/ horizontal distance of the ramp
Rise of the ramp = 52 feet
Horizontal distance = 80 feet
Grade of the ramp = 52 feet/80 feet
= 0.65
The grade of the ramp is 0.65
Rounding up to the nearest whole percent
Grade of the ramp = 0.65 × 100
= 65%
Therefore, the grade of the ramp to the nearest whole percent = 65%

An auditorium has 50 rows of seats. The first row has 20 seats, the second row has 21 seats, the third row has 22 seats, and so on, each row having one more seat than the previous row. How many seats are there altogether?
Answer:
1050
Step-by-step explanation:
I'm pretty positive it would be 1050 by multiplying 50 and 20 and adding 50
The total number of seats in the auditorium are 2225.
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that an auditorium has 50 rows of seats. The first row has 20 seats, the second row has 21 seats, the third row has 22 seats.
We can write the sequence as -
20, 21, 22, 23, 24, .......,
It is a arithmetic sequence. We can write the total number of seats in the auditorium as the sum of the terms of the sequence. We can write -
S{n} = (50/2)(2 x 20 + 49 x 1)
S{n} = 25(40 + 49)
S{n} = 25 x 89
S{n} = 2225
Therefore, the total number of seats in the auditorium are 2225.

It takes 15 minutes to preheat your oven to 325 degrees. For an oven preheated to 325 degrees, the recommended cooking time for a turkey is about 16 minutes per pound
(a) Use a formula to express the total time T, in minutes, needed to preheat the oven and then bake a turkey weighing p pounds.
(b) Use your formula from part (a) to find the approximate time required to prepare a turkey weighing 14 pounds.
(a) The formula for the total time T, in minutes, needed to preheat the oven and bake a turkey weighing p pounds is T = 15 + 16p.
(b) The approximate time required to prepare a turkey weighing 14 pounds is 239 minutes.
We have,
(a)
To express the total time T, in minutes, needed to preheat the oven and then bake a turkey weighing p pounds, we can use the formula:
T = 15 + 16p
The first term, 15, represents the time needed to preheat the oven to 325 degrees (in minutes).
The second term, 16p, represents the recommended cooking time per pound for a turkey weighing p pounds (in minutes).
(b)
Using the formula T = 15 + 16p, we can find the approximate time required to prepare a turkey weighing 14 pounds:
T = 15 + 16 * 14
T = 15 + 224
T = 239
Therefore, the approximate time required to prepare a turkey weighing 14 pounds is 239 minutes.
Thus,
(a) The formula for the total time T, in minutes, needed to preheat the oven and bake a turkey weighing p pounds is T = 15 + 16p.
(b) The approximate time required to prepare a turkey weighing 14 pounds is 239 minutes.

Answer:
[tex]n = -5[/tex]
Step-by-step explanation:
Given
[tex]Digit = 0.000025[/tex]
Required
Rewrite using scientific notation, then find n
[tex]Digit = 0.000025[/tex]
Express as fraction
[tex]Digit =\frac{25}{1000000}[/tex]
This can be splitted to
[tex]Digit = 25 * 10^{-6}[/tex]
The first number must be between 1 and 10; hence, 25 can be expressed as 2..5 * 10
[tex]Digit = 2.5 * 10* 10^{-6}[/tex]
Apply law of indices
[tex]Digit = 2.5 * 10^{1-6}[/tex]

Answer:
Domain: x ≥ 7
Range: y ≥ -1
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
Range is the set of y-values that can be outputted from function f(x).
We know that we can't take a square root of a negative and get a real number. The closest we can get is the square root of zero, no less.
What x-value renders the square root 0? x = 7 does, and we can't go less than that or we will get imaginary numbers. Therefore, the domain is x ≥ 7.
To find the range, we simply solve the rest of the function when x = 7, as we cannot go any lower.
y = 0 - 1
y = -1
Therefore, our range has to be y ≥ -1 because that would be the lowest y-value outputted from the lowest x-value.

Diego arranges the students in his math class from shortest to tallest and measures the height in inches of each student in the class. Use the shape of the distribution to compare the mean and median. Are the mean and median equal? If not, which is greater? Explain your reasoning.
Answer:
Explained below.
Step-by-step explanation:
A graph is formed using the height of students in Diego's math class.
It is provided that he arranges the students from shortest to tallest and measures the height in inches of each student in the class.
A distribution is known as to be skewed to the right, or positively skewed, when maximum of the data are collected on the left of the distribution and the graph has a longer tail towards the right.
For a positively skewed data: Mean > Median
A distribution is said to be skewed to the left, or negatively skewed, if maximum of the data are collected on the right of the distribution and the graph has a longer tail towards the left.
For a negatively skewed data: Mean < Median
A distribution is said to be symmetric, if maximum of the data are collected in the middle of the distribution and the graph has equal proportion of tails on both sides.
For a symmetric data: Mean = Median
I received a letter from your competitor that mentions a savings of 15% over your prices. Can you match this offer? My current rate is $129.00 per month
Complete question :
I received a letter from your competitor that mentions a savings of 15% over your prices. Can you match this offer? My current rate is $129.00 per month." Representative: "We will match any competitive offer. Your adjusted rate will be __________ dollars per month."
Answer:
$109.65
Step-by-step explanation:
Given the following :
Current rate = $129.00
Savings on current rate = 15%
Therefore, the adjusted rate will be 15% off the currently charged rate.
15% of $129.00
(15/ 100) × $129.00
0.15 × $129.00 = $19.35
Adjusted rate = current rate - adjustment
Adjusted rate = $129.00 - $19.35
Adjusted rate = $109.65
Hence, complete response :
We will match any competitive offer. Your adjusted rate will be $109.65 dollars per month."

Step-by-step explanation:
Distance travelled = 166.25 miles
gallons of gas used = 9 gallons
To find : 1 gallons of gas = ? miles
In unitary method, we have to obtain unit quantity. So, to find the distance travelled using 1 gallons of gas, 166.25 is divided by 9
[tex] \sf{ \frac{166.25}{9} }[/tex]
[tex] \dashrightarrow{ \sf{18.472 \: miles}}[/tex]
