Which of the following statements describes an angle bisector of angle ABC?
heagarty maths
Answer:
Given an angle ABC, it is possible to construct a line BF that divides the angle into two equal parts using only a straightedge and compass. Such a line is called an angle bisector. ... If we then construct the line BF, it will divide the original angle ABC into two equal angles.

The radius of a circle is 4 meters. What is the area of a sector bounded by a 135° arc?
Give the exact answer in simplest form.
Answer:
The area of the sector of the circle is approximately
Step-by-step explanation:
The given parameters of the circle having a shaded sector are;
The radius of the circle, r = 4 meters
The measure of the arc bounding the sector = 135°
The area of a sector of a circle, 'A', is given as follows;
[tex]A = \dfrac{\theta}{360 ^{\circ}} \times \pi \times r^2[/tex]
Therefore, the area, 'A' of the given sector of the circle, is given as follows;
[tex]A = \dfrac{135 ^{\circ}}{360 ^{\circ}} \times \pi \times (4\ cm)^2 \approx 18.85 \ cm^2[/tex]
The area of the sector of the circle, with radius 4 cm and bounded by an arc, A ≈ 18.82 cm².

The population of a small town over four years is recorded in the chart
below, where 2013 is represented by x= 0. The population, P(x), for these
years can be modeled by the function P(x) =aby, where bis rounded to the
nearest thousandth. Whkh statements about the function are true?
Answer:
1) I and III
Step-by-step explanation:
The equation of an exponential function is given by:
y = abˣ
where x is an independent variable, y is a dependent variable, a is the initial value of y (that is value of y at x = 0), b is greater than 1 for an exponential growth while b < 1 for an exponential decay.
Given that x represent years and P(x) represent population. 2013 is represented by x= 0, hence:
At the year 2013 (x = 0), the population is 3810, hence a = 3810.
The equation becomes:
P(x) = 3810(b)ˣ
At 2014 (x = 1), the population is 3943. Hence:
3943 = 3810(b)¹
3810b = 3943
b = 1.035.
Therefore a = 3810, b = 1.035. The correct option is 1) I and III
Since b > 1, this is an exponential growth.

What is the average rate of change for this exponential function for the interval from x = 7 to x = 8?
Answer:
4374
Step-by-step explanation:
Since, we are given table for x and y values
and table for average rate of changes
we can see the pattern of average rate of change
average rate of change for 5 to 6 is three times average rate of change for 4 to 5
but we have to find
average rate of change for 7 to 8
so, using same pattern
average rate of change for 6 to 7 is three times average rate of change for 5 to 6
average rate of change for 7 to 8 is 3*3( average rate of change for 5 to 6)
so, we can plug value
average rate of change for 7 to 8 is 3*3*486
average rate of change for 7 to 8 is 4374
Daniel goes out to lunch. The bill, before tax and tip, was $14.20. A sales tax of 8% was added on. Daniel tipped 24% on the amount after the sales tax was added. What was the total cost of the meal, plus tax and tip? Round to the nearest cent.
Answer: $19.02
Step-by-step explanation:
First find the sales tax paid. It will be paid on the cost of the meal:
= 14.20 * 8%
= $1.14
Then find the tip which was done after the sales tax was added:
= 24% * (14.20 + 1.14)
= 24% * 15.34
= $3.68
The total cost is:
= Gross amount + Sales tax + tip
= 14.20 + 1.14 + 3.68
= $19.02

Ravi bought 3 pens and 4 notebooks for $28. Lola bought 4 pens and 8
notebooks at the same store for $52. How much does one notebook cost?
Answer:
5.50 Each
Step-by-step explanation:
Answer:
Step-by-step explanation:
3P + 4N = 28
6P+ 8N = 56
4P +8N 52
2P = 4
P = 4/2 = 2 = $2
3(2)+4N = 28
4N = 28-6=22
N = 22/4 = 5.5= $5.50= cost of one notebook

Answer:
-1.2
Step-by-step explanation:
3n + 5 = 1/2(11n + 16)
3n + 5 = 5.5n + 8
5 = 2.5n + 8
-3 = 2.5n
-3/2.5 = n
-1.2 = n
Hope this helps!
Answer:
[tex]n=-1.2[/tex]
Step-by-step explanation:
First, solve both sides of the equation:
[tex]3n+5=\frac{1}{2} (11n+16)[/tex]
[tex]3n+5=(\frac{1}{2} )(11n)+(\frac{1}{2} )(16)[/tex] (Distribute)
[tex]3n+5=\frac{11}{2} n+8[/tex]
Then, subtract 11/2 n from both sides:
[tex]3n+5-\frac{11}{2}n=\frac{11}{2} n+8-\frac{11}{2} n[/tex]
[tex]\frac{-5}{2}n+5=8[/tex]
Now, subtract 5 from both the sides:
[tex]\frac{-5}{2} +5-5=8-5[/tex]
[tex]\frac{-5}{2} n=3[/tex]
For the last step, multiply both the sides by 2 / -5
[tex](\frac{2}{-5} )*(\frac{-5}{2} )=(\frac{2}{-5} )*(3)[/tex]
[tex]n=\frac{-6}{5}[/tex]
Convert it to decimal:
[tex]n=-1.2[/tex]

A board 60 in. long is cut into two parts so that the longer piece is 5 times the shorter. What are the lengths of the two
pieces?
Answer:
5x = 5(10) = 50 inches
Step-by-step explanation:
Let x = length of shorter piece then
5x = length of the longer piece
.
x + 5x = 60
6x = 60
x = 10 inches (shorter piece)
.
Longer piece:
5x = 5(10) = 50 inches

Corinne is planning a beach vacation in July and is analyzing the daily high temperatures for her potential destination.She would like to choose a destination with a high median temperature and a small interquartile range.She constructed box plots shown in the diagram below.
Which destination has a median temperature above 80 degrees and the smallest interquartile range?
(1)Ocean Beach (2)Whispering Palms (3)Serene Shores (4)Pelican Beach
Answer:
4
Step-by-step explanation:
Pelican Beach has a median temperature above 80 degrees and the smallest interquartile range.
What is a box plot?'A boxplot is a standardized way of displaying the distribution of data based on a five number summary, minimum, first quartile, median, third quartile, and maximum. It can tell us about the outliers and what their values are.'
According to the given problem,
In the given box plots, Whispering Palms and Pelican Beach has a median temperature of above 80 degrees. The median is the middle-most line that divides the box plot into two parts. Their median is approximately 85 degrees.
The interquartile range is the difference between the end points of the box plot.
Pelican Beach has the smallest interquartile range since the difference between the end points is less than the interquartile range of Whispering Palms.
Hence, we can conclude, Pelican Beach ahs the median temperature above 80 degrees and the smallest interquartile range.

What is the volume of a cone that has a height of 10 feet and a base with a surface area(B) of 9 square feet?
Answer:
30 cubic feet
Step-by-step explanation:
According to the scenario, calculation of the given data are as follows,
Height of cone (h) = 10 feet
Base surface area = π[tex]r^{2}[/tex] = 9 sq. feet
So we can calculate the volume of cone by using following formula,
volume of cone = (1/3)π[tex]r^{2}[/tex]h
By putting the value in the formula, we get
Volume of cone = (1/3) 9 × 10

An experience bricklayer can construct a small wall in 3 hours. An apprentice can complete the job in 5 hours. Find how long it takes if they work together. Show work.
Answer:
Step-by-step explanation:
If the bricklayer can construct the wall in its entirety in 3 hours, then he can get 1/3 of the job done in an hour.
If the apprentice can get the whole job done in 5 hours, then he can get 1/5 of the job done in an hour. If they both work together on said job, the equation is
[tex]\frac{1}{3}+\frac{1}{5}=\frac{1}{x}[/tex] and now we solve for x. Multiply everything by the LCM to get rid of the fractions. That would be 15x:
[tex]15x(\frac{1}{3}+\frac{1}{5}=\frac{1}{x})[/tex] and doing that gives us
5x + 3x = 15 and
8x = 15 so
x = 1.875 hours which is 1 7/8 hours which is also 1 hour and 52 1/2 minutes.
