Answer:
Solution given:
perpendicular [p]=20miles
base[b]=21Mile
hypotenuse [h]=?
we have
By using Pythagoras law
h²=p²+b²
h²=20²+21²
h=√841
h=29miles
he would walk 29 miles on the way back
The students who attend Memorial High School have a wide variety of extra-curricular activities to choose from in the after-school program. Students are 38% likely to join the dance team; 18% likely to participate in the school play; 42% likely to join the yearbook club; and 64% likely to join the marching band. Many students choose to participate in multiple activities. Students have equal probabilities of being freshmen, sophomores, juniors, or seniors.What is the probability of the intersection of being a junior and participating in marching band?

Answer:
60
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

Answer:
Area of ¼th part of circle =¼πr²=¼×3.14×12²
=113.04in²
Area of rectangle ABCD=l×b=8×17=136in²
Area of rectangle DEFG=l×b=5×3=15in²
Total area : 113.04+136+15=264.04 =264 square inches.
Answer:
area = 263.04 in²
Step-by-step explanation:
area = (8 x 17) + (5 x 3) = (0.25 x 3.14 x 12²) = 135 + 15 + 113.04 =263.04 in²

Find the Circumference of a circle with a Diameter of 9 inches Group of answer choices 9 pi inches 9 pi inches^2 9 pi inches^3 108 pi inches
Answer: [tex]9\pi\ in.[/tex]
Step-by-step explanation:
Given
The diameter of a circle is [tex]d=9\ in.[/tex]
So, the radius is [tex]r=\frac{d}{2}=4.5\ in.[/tex]
The circumference is given by [tex]2\pi r[/tex]
Insert the values
[tex]\Rightarrow 2\pi \cdot 4.5\\\Rightarrow 9\pi \ in.[/tex]
Thus, the circumference of the circle is [tex]9\pi\ in.[/tex]

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
what is x??? Please explain.
Answer:
78°
Step-by-step explanation:
when two lines intersect it creates 4 seperate angles, here it gives us 78°, and we know that the angle across from it is the same, so they equal.

Step-by-step explanation:
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

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.

Answer:

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

Step-by-step explanation:
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.
