Find the area and perimeter of the shaded regions below. Give your answer as a completely simplified exact value in terms of pi (no approximations). The figures below are based on semicircles or quarter circles.
*I found the area but I can't seem to find the perimeter
Answer:
[tex] A=(8 \pi +40) cm^2 [/tex]
[tex] P=(4 \pi + 4\sqrt {29}) \: cm[/tex]
Step-by-step explanation:
For semicircle:
Diameter = 8 cm
Radius (r) = 8/2 = 4 cm
For triangle:
Base (b) = 8 cm
Height (h) = 10 cm
Area of the shaded region
[tex] A=\frac {1}{2} \pi r^2 +\frac {1}{2}b.h[/tex]
[tex] A=\frac {1}{2} \pi (4)^2 +\frac {1}{2}(8).(10)[/tex]
[tex] A=(8 \pi +40) cm^2 [/tex]
By Pythagoras Theorem:
[tex] AC = BC = \sqrt {4^2 +10^2}[/tex]
[tex] AC = BC = \sqrt {16 +100}[/tex]
[tex] AC = BC = \sqrt {116}[/tex]
[tex] AC = BC =2\sqrt {29}[/tex]
[tex] P= \frac {1}{2} \times 2\pi r+ AC + BC[/tex]
[tex] P= \pi (4)+ 2\sqrt {29} + 2\sqrt {29}[/tex]
[tex] P=(4 \pi + 4\sqrt {29}) \: cm[/tex]
Para decorar una pared se disponen de tiras de papel azules de 15 cm, verdes de 20 cm, y rojas de 25 cm. En la pared se quiere armar tres líneas del mismo tamaño, una de cada color y sin cortar ninguna tira. a) ¿Cuánto va a medir la menor línea que se puede armar con cada color? b) ¿Cuántas tiras se deben utilizar? c) ¿Cuántas de cada color?
Answer:
a) Smallest line that can be made with each color = 300 cm
b) Total strips should be used = 47 strips
c) Total strips used of blue color = 20
Total strips used of green color = 15
Total strips used of red color = 12
Step-by-step explanation:
Given - To decorate a wall, there are 15 cm blue, 20 cm green, and 25 cm red strips of paper. On the wall you want to build three lines of the same size, one of each color and without cutting any strip.
To find - a) How long is the smallest line that can be made with each color?
b) How many strips should be used?
c) How many of each color?
Proof -
a)
For the smallest line that can be made with each color, we just have to find the lcm (least common multiple) of the 3 srtips.
Firstly,
Decompose the 3 strips to its prime factors , we get
15 = 3×5
20 = 2²×5
25 = 5²
So,
The Lcm(15, 20, 25) = 3×2²×5² = 3×4×25 = 300
∴ we get
Smallest line that can be made with each color = 300 cm
b)
Now,
Total strips used = 300 cm
Strips used by 15 cm blue = [tex]\frac{300}{15}[/tex] = 20 strips
Strips used by 20 cm green = [tex]\frac{300}{20}[/tex] = 15 strips
Strips used by 25 cm red = [tex]\frac{300}{25}[/tex] = 12 strips
So,
Total strips should be used = 20 + 15 + 12 = 47 strips
c)
Total strips used of blue color = 20
Total strips used of green color = 15
Total strips used of red color = 12

Answer:
1441.08 cubic inches
Step-by-step explanation:
Blue
V = L * W * H
L = 15
W = 9
H = 9
V = 9 * 9 * 15 = 1215 CU IN
YELLOW
Diameter = 6
Height = 8
radius = d/2
radius = 6/2
radius = 3
Volume = pi*r^2 * h
Volume = 3.14*3^2 * 8
Volume = 226.08 Add
1441.08

Alina has to spend $30 000 on expenses each year. If that amount of money is 40% of her total yearly earnings, then how much money does Alina make per year?
Answer:
$75000
Step-by-step explanation:
Given data
Let her yearly earnings be x
so
40% of x= $30000
40/100*x=30000
0.4x=30000
x=30000/0.4
=$75000
Hence the total amount made per years is
$75000

4(m-9)=2(2m+1)-40
What is the answer
Answer: i think that's right if not than t don't have a solution
Step-by-step explanation:4(m−9)=2(2m+1)−40
(4)(m)+(4)(−9)=(2)(2m)+(2)(1)+−40(Distribute)
4m+−36=4m+2+−40
4m−36=(4m)+(2+−40)(Combine Like Terms)
4m−36=4m+−38
4m−36=4m−38
Step 2: Subtract 4m from both sides.
4m−36−4m=4m−38−4m
−36=−38
Step 3: Add 36 to both sides.
−36+36=−38+36

14
Answer:
7.2
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 +12^2 = 14^2
a^2 = 14^2 - 12^2
a^2 = 196 - 144
a^2 = 52
a = square root of 52 = 7.2
