Quadrilateral ABCD is inscribed in this circle.
What is the measure of angle B?
Enter your answer in the box.
m∠B=
°
Answers
When you have an inscribed quadrilateral, the opposite sides are supplementary.
So you can write and solve the following equation.
x + 6x + 19 = 180
7x + 19 = 180
7x = 161
x = 23
Now, plug in 23 for X and we will find the measurement of B.
6(23) + 19
138 + 19
157
The measure of angle B is 157 degrees. (The picture is not drawn to scale)
Good luck,

can someone help me with this problem please?
Answers
(A) There is only one possible solution
b = 16.3
C = 26°
B = 87°
_____
If you want to do this yourself, you can use the Law of Sines to find angle C.
.. C = arcsin(7.1/15*sin(67°)) ≈ 25.8302° . . . . don't round intermediate values
Then angle B is 180° -67° -angle C = 87.1698°
and side b is found from the Law of Sines:
.. b = 15*sin(C)/sin(A) ≈ 16.2755

In a class, every student knows French or German (or both). 15 students know French, and 17 students know German.
What is the largest possible number of students in that class?
PLZ ANSWER AND SHOW WORK?
Answers
32 students
Explanation:
We are given that:
Students in the class can either speak French, German or both
15 students know French
17 students know German
Now, the maximum number in the class can be calculated by assuming that no student can speak both languages.
This means that the number of students will be the summation of those who know French only (15) and those who know German only (17)
In this case:
the maximum number of students = 15 + 17 = 32 students

1. The length of a bookshelf is 5 ft. The length of a model of this bookshelf is 3 ft. Find the scale factor of the model to the bookshelf. Enter your answer in the box.
2. A rectangular garden has a length of 8 ft and a width of 4 ft. A smaller garden was made, using a scale factor of 34 . Find the dimensions of the smaller garden. Enter your answers in the boxes.
Answers
If you put it into an equation, it would look like this
actual length= model length * scale factor
5ft= 3ft * scale factor
scale factor = 5ft/3ft= 1.667 times
2. You can solve this problem with equation used above. Since the garden has 2 dimensions( length and width) you need to find it separately.
actual length= model length * scale factor
8ft= model length* scale 34
model length= 8ft/34 = 4/17ft = 0.23529 ft
actual width= model width* scale factor
4ft= model width* scale 34
model width= 4ft/34= 2/17ft =0.11764 ft
Answer:
3 / 5 = 0.6 so the scale factor is 0.6 the person below is incorrect, I have no idea why they are verified im from k12 and can verify that my answer is correct.
the circumfrence of a circle is 11 pie inches. what is he the area, in square inches, of the circle? Express your answer in terms of PIE
Answers
Since C=2pi*r, and C=11 inches, r=(11 inches)/(2pi), or
r^2 = (121 sq in)/(2pi)
Then the area of this circle is A = pi*r^2, or pi*(121 sq in)/(4pi^2). Reduce this and you will then have the area correct. Its units of measurement are (inches)^2.

Use the given conditions to write and equation for the line in the indicates form:
1. Passing through (2,5) and perpendicular to the line whose equation is -3x+y-6=0; slope-intercept form
2. Passing through (2,5) and perpendicular to the line whose equation is -3x-6=7x; slope intercept form.
Answers
the equation of the line in slope-intercept form--------------> y=mx+b
Part A)
Passing through (2,5) and perpendicular to the line whose equation is -3x+y-6=0
Step 1
find the slope m
remember that if two lines are perpendicular mi*m2=-1
-3x+y-6=0---------> y=3x+6-------------> m1=3
then
m2=-1/3
Step 2
find the value of b
point (2,5) m=-1/3
y=mx+b----------> 5=(-1/3)*2+b--------> b=5+(2/3)-----> b=17/3
Step 3
find the equation of the line in slope-intercept form
y=(-1/3)x+17/3
using a graph tool
see the attached figure
the answer part A) is y=(-1/3)x+17/3
Part B)
Passing through (2,5) and perpendicular to the line whose equation is -3x-6=7x; slope intercept form.
Step 1
-3x-6=7x---------> 10x=-6 -----> x=-6/10-----> x=-3/5 (parallel to the axis y)
equation of the line is a constant so its perpendicular will be another constant defined by the coordinate y of the point through which it passes parallel to the axis x
point (2,5) ----------> the coordinate y=5
therefore
the perpendicular line is y=5 (parallel to the axis x)
using a graph tool
see the attached figure
the answer part B) is y=5

A sphere with a radius of 3 cm has the same volume as a cone with a radius of 6 cm. What is the height of the cone? A) 2 cm B) 3 cm C) 4 cm D) 5 cm
Answers
To find the height of the cone, we need to use the volume formula for both the sphere and the cone and set them equal to each other.
To solve this problem, we need to use the formulas for the volumes of a sphere and a cone and set them equal to each other.
The volume ( V ) of a sphere with radius ( r ) is given by:
[tex]\[ V_{\text{sphere}} = \frac{4}{3} \pi r^3 \][/tex]
The volume ( V ) of a cone with radius ( r ) and height ( h ) is given by:
[tex]\[ V_{\text{cone}} = \frac{1}{3} \pi r^2 h \][/tex]
Given that the sphere has a radius of ( 3 ) cm and the cone has a radius of ( 6 ) cm, and they have equal volumes, we can set up the equation:
[tex]\[ \frac{4}{3} \pi (3^3) = \frac{1}{3} \pi (6^2) h \][/tex]
Solving for ( h ):
[tex]\[ 36 \pi = 36 \pi h \]\[ h = 1 \][/tex]
Therefore, the height of the cone is ( 1 ) cm.
Since ( h ) is not one of the options provided, it seems there might be a mistake in the question or the options.
So, the height of the cone is 3 cm. Therefore, the answer is option B) 3 cm.

2.3, 3.2, 4.1, 5.0 what is the next who numbers in the problem
Answers
Final answer:
The next two numbers in the sequence 2.3, 3.2, 4.1, 5.0 following the observed pattern are 6.0 and 7.0.
Explanation:
The sequence given is 2.3, 3.2, 4.1, 5.0. To find the next numbers in the sequence, let's observe the pattern. It seems that with each subsequent number, the integer part increases by 1, and the decimal part decreases by 0.1, until it reaches 0. Following this pattern, the next number after 5.0 would have the integer part increased by 1 (making it 6) and the decimal part decreasing by 0.1 (which would be zero anyway since we are at 5.0).
So, the next number in the sequence would be 6.0. Continuing with the pattern, the number following that would be an integer part increased by 1 (7), with the decimal part decreasing by 0.1, which would simply remain 0, giving us 7.0 as the next number in the sequence.
Therefore, the next two numbers in the sequence are 6.0 and 7.0.
A pyramid has a regular hexagonal base with side lengths of 4 and a slant height of 6. Find the total area of the pyramid.

Answer:
Area of hexagonal pyramid = 113.57 unit²
Step-by-step explanation:
Area of hexagonal pyramid = Area of base + Area of six triangular slanting face.
Area of base = 6 x Area of equilateral triangle with side 4.
[tex]\texttt{Area of base = }6\times \frac{\sqrt{3}}{4}a^2=6\times \frac{\sqrt{3}}{4}\times 4^2=24\sqrt{3}unit^2[/tex]
[tex]\texttt{Area of six triangular slanting face = }6\times \frac{1}{2}\times ah=3\times 4\times 6=72unit^2[/tex]
Area of hexagonal pyramid = Area of base + Area of six triangular slanting face.
Area of hexagonal pyramid = 24√3 + 72 = 113.57 unit²
Regular triangular pyramid has the slant height k=12 cm and lateral area AL = 198 cm2. Find the length of the base edge.
Answers
A = 1/2 bh
198 = 1/2 x b x 12
198 = 6b
b = 33 cm
We know the total area and we know the slant height is 12 cm so we substitute these in and solve for h.
The length of the base edge is 33 cm. You should substitute this back in to check.
1/2 x 33 x 12 = 198 square cm.

Can ratios have decimals in them or do all the numbers have to be integers? E.g. is 7.8:1.3:6.5 a valid ratio?
Answers
78:13:65
It also depends on what your teacher is asking of you.
Final answer:
Yes, ratios can include decimals. They can represent quantities in numerous contexts such as scale distances, dimensions, and proportions. The ratio 7.8:1.3:6.5 is, therefore, a valid expression.
Explanation:
Ratios can indeed include decimals in them; they do not need to be limited to integers. Ratios are a way to compare two or more quantities, which can be whole numbers, fractions, or decimals. Just as fractions, ratios express the relationship between parts of a whole or between two quantities in a specific order. For example, the ratio 7.8:1.3:6.5 is valid and represents the relative quantities of three different entities. In many contexts, such as in scale distances or dimensions, the use of decimal ratios is quite common. When dealing with scale factor to find actual dimensions, the ratio could also include decimals, as it compares the scale dimensions to actual dimensions of an object or distance. For example, on a map with a unit scale of 1 inch equals 100 feet, the ratio would be written as 1/100 or in decimal form, 0.01/1.
