Answer:
30 and 110 degrees
Step-by-step explanation:
The angles sum to 360 degrees
you have 60 + 160 = 220 leaving 140 more in a ratio 3:11
one is 3 / (3+11) = 3/14 3/14 * 140 = 30 the other is 110

Step-by-step explanation:
z = 180° - 113° = 67°
sum of angles of quadrilateral shape = 360°
y = 360° - ( 67° + 81° + 106° ) = 106°
Can someone help me find the volume of this?
Answer:
97.2 m³
Step-by-step explanation:
The volume of a triangular prism is half the volume of a rectangular prism with the same length, width, and height.
V = 1/2LWH
V = 1/2(9 m)(7.2 m)(3 m) = 97.2 m³
_____
Additional comment
The relation we used above comes from the more general formula for the volume of a prism:
V = Bh
where B is the area of the base.
You know a rectangular base will have an area of ...
A = bh
and a triangle with the same base and height will have an area of ...
A = 1/2bh
That is, the base area of a triangle is half that of a rectangle with the same dimensions. When we use this fact in the volume formula, we find the volume of a triangular prism is 1/2 that of a rectangular prism with the same length, width, and height.
6. Annie has a cube that has a side length of 9 cm. What is the surface area of the cube?
Answer:
486
Step-by-step explanation:
Surface area means the area of each side added upIn a cube, every side is the samethe area of one side = 9 * 9 = 81, since it is a square (width*height) and width and height are the same. in a cube there are 6 sidesso there are 6 sides with area 8181 * 6 = 486Solve for a side in right triangles
Answer:
The answer is AC = 3.76
Step-by-step explanation:
CohCahToa
Coh: sin(theta) = Opp/Hyp
sin(theta°) = AC/AB
sin(70°) = AC/4
AC = 4*sin(70°)
AC ≈ 3.758770483
AC = 3.76
Answer:
AC = 3.76
Step-by-step explanation:
The opposing side of ∠B needs to be found, where the value of the hypotenuse is given. Take the sin ratio.
sin∠B = AC/4sin70° = AC/40.94 = AC/4AC = 4 x 0.94AC = 3.76If two lines intersect, their intersection is___________

Write the equation of the circle
with center (2,-5) and radius of 4.
*
Answer:
[tex](x - 2) {}^{2} + (y + 5) {}^{2} = 16[/tex]
Step-by-step explanation:
Equation of circle is:
[tex](x - h) {}^{2} + (y - k) {}^{2} = r {}^{2} \\ [/tex]
Here (h,k) are the coordinates of center and r is radius
(h,k) =(2,-5)
r. = 4
plug in the values of h,k and r
[tex](x - 2) {}^{2} + (y - ( - 5)) {}^{2} = 4 {}^{2} \\ (x - 2) {}^{2} + (y + 5) {}^{2} = 16[/tex]
Answer:
[tex](x-2)^2+(y+5)^2=16[/tex]
Step-by-step explanation:
Equation of a circle
[tex](x-a)^2+(y-b)^2=r^2[/tex]
(where (a, b) is the center and r is the radius)
Given:
center = (2, -5)radius = 4Substitute the given values into the equation:
[tex]\implies (x-2)^2+(y-(-5))^2=4^2[/tex]
[tex]\implies (x-2)^2+(y+5)^2=16[/tex]
Solve for x in the given equation: ax - b = c
An equation is formed of two equal expressions. The value of x is the equation ax-b=c is (c+b)/(a).
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The solution of x in the given equation can be written as,
[tex]ax - b = c\\\\ax = c+b\\\\x = \dfrac{c+b}{a}[/tex]
Hence, the value of x is the equation ax-b=c is (c+b)/(a).

You mix the letters S,E,M,I,T,R,O,P,I,C,A, and L throughly.Without looking,you draw one letter.Find the probability that you select a vowel.Write your answer in simplest form.
A. 12/5
B. 5/12
C. 1/3
D. 7/12
I need this answer in 5 MINUTES!
Answer:
B. 5/12
Explanation:
Total Letters mixed: {S, E, M, I, T, R, O, P, I, C, A, L} = 12 Letters
There are 5 vowels and they are: 'a', 'e', 'i', ' o', and 'u'
In here the vowels are: E, I, O, I, A = 5 vowels here
So,
probability: number of favourable outcomes/total number of outcomes

The track is 9.76 m wide all the way around. What is the distance around the outside of the track? Explain or show your reasoning.
Answer:
The distance around the outside of the track is 4183.58m².
Step-by-step explanation:
The area of running track that goes around the field is 9.76m
To proof :
Formula -
(Area of rectangle = length × breadth)
(Area of running track = outside area - inside area)
First case (outside),
length = 73 +2× 9.76
= 92.52m
Breadth = 84.39 m
radius of outside semi circle,
= 46.26m
outside area = area of rectangle + 2 × area of the semi-circle
= 92.52 x 84.39 + 3.14 x 46.26 × 46 × 26
= 7807.76+6719.56
Second case,
radius of the semi-circle,
=36.5m
inside area = area of rectangle + 2x area of the semi-circle
=73x 84.39+ 3.14x 36.5×36.5
= 6160.47 +4183.27
= 10343.74m²
Now,
Area of running track = 14527.32 m²- 10343.74m²
= 4183.58m²
The distance around the outside of track is 4183.58m².

Answer:
[tex]\frac{-3}{-26}[/tex]
Step-by-step explanation:
[tex]\frac{-x-8}{x^{2}-4x-21}[/tex] is what you are looking for.
So with x = -5, it would look like this
[tex]\frac{-(-5)-8}{-5^{2}-(-5)4-21}[/tex]
Simple math now.
-(-5) is 5
[tex]-5^{2} = -25[/tex]
-5 * -4 = 20.
So it should be [tex]\frac{5-8}{-25+20-21}[/tex]
5-8=-3
-25+20-21 = -26
So the answer is[tex]\frac{-3}{-26}[/tex]
