How many triangles exist with the given angle measures?
60°, 60°, 60°
A. Exactly one unique triangle exists with the given angle measures.
B. No triangle exists with the given angle measures.
C. More than one unique triangle exists with the given angle measures.
Answer:
The sum of the angles in a triangle is 180°, so the angles do form a triangle. Since two of the three angles are congruent, the triangle is an isosceles triangle. An infinite number of isosceles triangles exist with different side lengths. Therefore, more than one triangle exists with the given angle measures.

hghgh heres another, i'll upload two more questions so that way im not nagging anyone to help me out^^
A slightly more accurate value is 38.28 cm^2, when using pi = 3.14
=================================================
Explanation:
The vertical height of the rectangle is 4 cm, which forms the diameter of the semicircle. The diameter cuts in half to 4/2 = 2, which is the radius.
The area of a full circle with radius r = 2 cm is approximately pi*r^2 = 3.14*2^2 = 12.56 square cm.
Cut that in half to get (12.56)/2 = 6.28 square cm. This is the approximate area of the semicircle.
--------
The area of the rectangle is length*width = 6*4 = 24 square cm.
The triangle has its bottom portion of 4 cm (because 10-6 = 4) and its height is 4 cm, so we get the triangle area of base*height/2 = 4*4/2 = 8 square cm.
The last thing we do is add up all the results we got:
6.28 + 24 + 8 = 38.28
That rounds to 38 square cm when rounding to the nearest whole number.
Let measure of angle B be 18 degrees and BC = 9. Find the length of AC, BA and the measure of angle C. Round to 1 decimal place when needed. Show all of your work.
Answer:
m∠C = 72°
BA = 8.6
AC = 2.8
Step-by-step explanation:
We can start by finding the sum of all angles in a triangle to find angle C. The sum of all angles is 180°, so we can write the equation:
m∠A + m∠B + m∠C = 180°
And substitute what we have:
90° + 18° + m∠C = 180°
108° + m∠C = 180°
m∠C = 72°
In order to find the side BA, we can use trig functions. We are given the hypotenuse and we are looking for the side adjacent to ∠B. The trig function that relates the two is cosine. We can set up the equation as follows:
cos(∠B) = [tex]\frac{BA}{BC}[/tex]
cos(18°) = [tex]\frac{BA}{9}[/tex]
9 * cos(18°) = BA
BA ≈ 8.559508647
And when we round, we get:
BA = 8.6
In order to find the side AC, we can use trig functions. We are given the hypotenuse and we are looking for the side opposite to ∠B. The trig function that relates the two is sine. We can set up the equation as follows:
sin(∠B) = [tex]\frac{AC}{BC}[/tex]
sin(18°) = [tex]\frac{AC}{9}[/tex]
9 * sin(18°) = AC
AC ≈ 2.781152949
We can round this to:
AC = 2.8

Sarah wanted to know how many of her fellow students have at least one cat at home. She randomly sampled 30 students from her school and 11 of them answered yes. What is the approximate proportion of students who have at least one cat?
A
0.11
B
0.27
C
0.33
D
0.37
The proportion of students who have at least one cat is 0.37
The correct option is : (D)
What is fraction?A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Total students samples=30
Students answered yes =11
The proportion of students who have at least one cat
= [tex]\frac{11}{30}[/tex]
= 0.367
≈ 0.37
Hence the proportion of students who have at least one cat is 0.37.

Rosa is picking out fabric for her bedroom. She has 6 fabric samples, and 2 of them are floral. What is the probability that a randomly selected fabric sample will be floral? Write your answer as a fraction or whole number.
Answer:
Probability of selected sample is floral = 1 / 3
Step-by-step explanation:
Given:
Number of fabric sample = 6 sample
Number of floral sample from all samples = 2 samples
Find:
Probability of selected sample is floral
Computation:
Probability of a sample = Favorable outcome / Total outcomes
Probability of selected sample is floral = Number of floral sample / Number of fabric sample
Probability of selected sample is floral = 2 / 6
Probability of selected sample is floral = 1 / 3

Given:
length of rectangle = 4 units
Height of rectangle = 2x + 6 units
To find:
Not given, so I will find area and perimeter of rectangle. If you want the length of the diagonal of the rectangle, please ask me.
Steps:
Perimeter of rectangle = 2(L + B)
= 2( 4 + 2x + 6 )
= 2( 10 + 2x )
= 2 * 10 + 2 * 2x
= 20 + 4x units
Area of rectangle = L * B
= 4 * (2x + 6)
= 4 * 2x + 4 * 6
= 8x + 24 units²
Therefore, the perimeter of the rectangle is 20 + 4x units, and the area of the rectangle is 8x + 24 units².
Happy to help :)
If you need any help, feel free to ask.
Answer:
we multiply 4 by 2x + 6
4(2x + 6) = 8x + 24
En france en 1900 la taille moyennes des femmes etait de 1,54 m et celle des hommes de 1,66 m. Entre 1900 et 2010 ces tailles moyeness ont augmentes de 5,55 %
Complete question :
En France, en 1900, la taille moyenne des femmes était de 1,54 m et celle des hommes de 1,66 m. Entre
1900 et 2010 ces tailles moyennes ont augmentées d'environ 5,55%.
Calculer, en mètres, l'arrondi au centième des tailles moyennes des femmes et des hommes en 2010.
Répondre :
Femmes = 1,63
Hommes = 1,75 m
Explication étape par étape:
Étant donné que :
Taille moyenne en 1900:
Hommes = 1,66 m
Femmes = 1,54 m
Pourcentage d'augmentation de poids d'ici 2010 = 5,55%
1 + 5,55% = 1 + 0,0555 = 1,0555
D'où,
Taille des femmes en 2010:
1,0555 * 1,54 = 1,62547 = 1,63 m
Pour la taille des hommes en 2010:
1,0555 * 1,66 m = 1,75213 = 1,75 m
Two recreational basketball teams, Eagleton and Hawkville, wanted to compare the heights of their players in inches.
The heights of Eagleton's basketball players are 70, 71, 72, 74, 74, 75, and 75. The mean height of the Eagleton players is 73 inches
The heights of Hawkville's basketball players are 70, 70, 71, 72, 72, 72, and 77. The mean height of the Hawkville players is 72 inches.
Which statement is true?
Team Hawkvilles's players heights vary the same amount as Team Eagleton's players heights.
The range of Eagleton's players heights is greater than the range of Hawkville's players heights.
Team Hawkville's players heights vary more than Team Eagleton's players heights.
Team Eagleton's players heights vary more than the heights of Hawkville's players.
Answer:
Option C
Step-by-step explanation:
Given -
Height of the Eagleton's basketball players are 70, 71, 72, 74, 74, 75, and 75.
The mean height of Eagleton's basketball players is 73 inches
Heights of Hawkville's basketball players are 70, 70, 71, 72, 72, 72, and 77. The mean height of the Hawkville players is 72 inches
The range of any given data set is the difference in the maximum and minimum value the frequencies with in the data set.
The range of Hawkville's basketball players is 77-70 = 7
The range of Eagleton's basketball players is 75-70 = 5
Hence, the height of Hawkville's basketball players vary more as compared to the height of players of Eagleton.

you want to solve the whole numbers and fraction parts sepreatly then combine.
Answer:
53/8
Step-by-step explanation:
[tex]16\frac{7}{8} -10\frac{1}{4}[/tex]
convert to improper fractions
[tex]\frac{7+16*8}{8} -\frac{1+10*4}{4}=\frac{135}{8} -\frac{41}{4}[/tex]
the common denominator is 8, so multiply the second fraction by [tex]\frac{2}{2}[/tex].
[tex]\frac{135}{8} -\frac{41*2}{4*2}=\frac{135}{8} -\frac{82}{8}[/tex]
subtract
[tex]\frac{135}{8} -\frac{82}{8}=\frac{135-82}{8}=\frac{53}{8}[/tex]

Answer:

Step-by-step explanation:
The outside of the circle will measure 360 all of our known values are added up to equal 240 so subtract it from 360 to get 120
Now divide 120 by half to get 60 since the outside is double the size of the inside
Hope this helps
Answer:
60
Step-by-step explanation:
Angle R is an inscribed angle so it is 1/2 of TS. Since a circle is 360 degrees, we find TS by subtracting (90 + 150) from 360 which gives us TS = 120.
x = 1/2(120) = 60 degrees
