28 in^2
Divide shape into one rectangle and two squares:
Area of rectangle:
10 x 2 = 20 in^2
Area of one square:
2 x 2 = 4 in^2
Multiply that by 2 because we have 2 squares similar in size:
4 in^2 x 2 = 8 in^2
Add the area of the rectangle and two squares:
20 in^2 + 8 in^2 = 28 in^2
Have a nice day
Hope this helps!
J + i + t = 36
j = 2i
t = j + 1.....t = 2i + 1
(2i + 1) + i + (2i) = 36
5i + 1 = 36
5i = 36 - 1
5i = 35
i = 35/5
i = 7 <=== Inez downloaded 7 songs
j = 2i = 2(7) = 14 <==Jane downloaded 14 songs
t = 2i + 1 = 2(7) + 1 = 15 <== Tracy downloaded 15 songs
Answer:
9pi approximately 28
Step-by-step explanation:
we have the formula - pi r^2
which we know the diameter is 6 m and the surface is a semi circle
the radius is 3 so then we have pi 3^2
which becomes 9pi which is about 28.2
rounding to 28
hope this helps!!

Answer:
Choose every tenth student entering the school and ask them if they like the dress code or not.
Step-by-step explanation:
This is a question of sampling. We need to make non-biased predictions using non-biased data. We can sample from every tenth student to stay proportional. Sampling many students can collect more data and can help keep the data non-biased.
