Hey,
So we have to solve this in multiple steps. Step 1 is to find the circumference of the semi-circle and multiply by three since there are three. Step 2 would be to find the perimeter of the rectangle. Step 3 would be to add those two together.
Step 1: To find the circumference of the semicircle use the formula pi (3.14) times radius (8 ÷ 2 = 4) times 2. After that we will divide by two since there is only half. After that we will multiply that answer by three.
C = 3.14 x 4 x 2
C = 12.56 x 2
C = 25.12
C = 25.12 ÷ 2
C = 12.56
Perimeter = 12.56 x 3 = 37.68
Step 2: To find the perimeter of the rectangle/square add all the sides (8).
Perimeter = 8 + 8 + 8 + 8 = 32
Step 3: Now add the two previous answers to get the final perimeter.
37.68 + 32 = 69.68
Final Answer: 69.68
Hope this helped!

Answer:
n= 21
c= 3x
Step-by-step explanation:
The expression is given as;
(3x⁷)⁴
Apply the brackets law of indices which states that :
If a term with a power is itself raised to a power then the powers are multiplied together
(xᵃ)ᵇ = xᵃˣᵇ
Applying the same;
(3x⁷)⁴ = 3x²¹
If 3x²¹ = c^n
Then n = 21
and
c= 3x
Answer:
Step-by-step explanation:
-4 + (5+6/ -6 × 5) -2
Solve the brackets first!
-4 + (11/ -30) -2
Add the -4 and -2
-6 + (-11/30)
[If you meant -2 multiplied by (-11/30) then , something like this, If not then continue after the bracket!:
-4 + (11/15)
(-60+11)/15
-49/15 Answer ]
Now,
-6 -11/30
(-180-11)/30
-191/30
Hope this helps!

Answer:
The value of T is 55°
Step-by-step explanation:
Using the theorem of parallel and equality,the angle of unknown angle equals to opposite one.
Or at least if you noticed,that angle is perpendicular,then 35+90=125;
180-125=55°
Trina borrowed $460 from a friend. Her friend charged her 5% simple annual interest.Let's solve how much will Trina owe her friend in total after 3 years? Use the simple interest formula to solve.
I = prt
I = (460)(0.05)(3)
I = 460 * 0.05 = 23
I = 23 * 3 years = 69 dollars is the interest.
Trina must pay her friend a total of $460 + 69 = 529.
