an umbrella has 12 evenly spaced ribs. If viewed as a flat circle of radius 11 units,
then what would be the area between two consecutive ribs of the umbrella
Answers
Answer:
Area = 121pi/12
~= 31.66 sq units
Step-by-step explanation:
They are talking about looking at an umbrella like its a circle. The radius is 11 units. That is from the center to the edge.
Consecutive means "in a row" or "next to each other" The 12 "ribs" are the like skeleton structure in the umbrella. But they cut the umbrella into 12 areas. They are asking for the area of one "slice". It is 1/12 of the area of the whole circle.
Area of a circle is
A = pi × r^2
Area of one slice is 1/12 of the whole.
A(1 slice)
= 1/12× pi × r^2
See image.

Find the missing variable. 3k+4(-k+2)=14k-22
Answers
Answer:
k=2
Step-by-step explanation:
Expanding gives
[tex]3k-4k+8=14k-22[/tex].
Further simplification yields
[tex]-k+8=14k-22[/tex]
[tex]15k=30[/tex]
[tex]k=2[/tex].
Step-by-step explanation:
Use the Distributive Property:
[tex]3k - 4k + 8 = 14k - 22[/tex]
[tex] - k + 8 = 14k - 22[/tex]
Add k to both sides:
[tex]8 = 15k - 22[/tex]
Add 22 to both sides:
[tex]30 = 15k[/tex]
Divide each side by 15:
[tex]2 = k[/tex]

Answers
3/5=12/x
reciprical of both sides
5/3=x/12
times twelve on both sides
x=20
Answer:
7.2 games, 2.4 times rate.
Step-by-step explanation:
Carla's team won 3 of 5 games which is 3/5 aka 60%.
Elena's team won games at the same rate which means Elena's team won about 7 games since it's 7.2/12 (60%). They won at the rate of 2.4 times while Carla wins at 3/5 rate.

I'm struggling to solve this.
I'm told to solve for i,
9x- 7i < 3 (3x -7u)
Answers
Answer:
i > 3u
Step-by-step explanation:
Let's solve for i.
9x−7i<3(3x−7u)
Step 1: Add -9x to both sides.
−7i+9x+−9x<−21u+9x+−9x
−7i<−21u
Step 2: Divide both sides by -7.
−7i ÷ -7 = -21u ÷ -7

Answers
Step-by-step explanation:
this is really simple : we only need to put the given x and y coordinate values into both equations and see, if both equations remain true.
(-2, -1) means x = -2, y = -1
first equation :
-1 = 3×-2 + 5 = -6 + 5 = -1
so, -1 = -1
true.
second equation :
-2 + -1 = -3
-3 = -3
true.
therefore, (-2, -1) is a solution to the linear system.

(5 feet long by 4 1/2 feet wide), what are two ways she could change
the length and/or width to give her that new area?
What would the new area be?
Answers
The two ways she could change the length and/or width are;
Multiply the length by a factor of 4 while leaving the width constantMultiply the width by a factor of 4 while leaving the length constantThe new area of the pen would be; 90ft²
Area of a penThe dimension of the pen given is;
5 feet long by 4 1/2 feet wideHence, the initial area of the pen is;
5 × 4.5 = 22.5 ft².Hence, to make the pen four times it's present area; Krista may multiply either of the length or width by a factor of 4.
And hence, the new area is; 22.5 × 4 = 90ft²

Q.2. 12 men are building a wall which is 8 m long, 6 m high and 22.5 cm thick using bricks. On this basis answer the following.
i. Find the volume of the cuboidal wall.
Length (l) = 800 mBreadth (b) = 6600 mHeight (h) = 22.5 cmSubstituting all the given values in the formula to find volume of cuboidal wall :
[tex] \begin{gathered}\qquad{\longrightarrow{\sf{V = LBH}}} \\ \\ \qquad{\longrightarrow{\sf{V = L \times B \times H}}} \\ \\ \qquad{\longrightarrow{\sf{V = 800 \times 600 \times 22.5}}} \\ \\ \qquad{\longrightarrow{\sf{V = 480000 \times 22.5}}} \\ \\ \qquad{\longrightarrow{\sf{\underline{\underline{\red{V = 1,08,00,000 \: {cm}^{3}}}}}}} \end{gathered}[/tex]
Hence, the volume of cuboidal wall is 1,08,00,000 cm³.
———————————————————————
ii. If the dimension of each brick is 25 cm × 11.25 cm × 6 cm, then find the volume of the brick.
Length (l) = 25 cmBreadth (b) = 11.25 mHeight (h) = 6 cmSubstituting all the given values in the formula to find the volume of cuboidal brick :
[tex] \begin{gathered}\qquad{\longrightarrow{\sf{V = LBH}}} \\ \\ \qquad{\longrightarrow{\sf{V = L \times B \times H}}} \\ \\ \qquad{\longrightarrow{\sf{V = 25 \times 11.25\times 6}}} \\ \\ \qquad{\longrightarrow{\sf{V = 281.25\times 6}}} \\ \\ \qquad{\longrightarrow{\sf{\underline{\underline{\pink{V = 1687.5 \: {cm}^{3}}}}}}} \end{gathered}[/tex]
