Step-by-step explanation:
a=0.15789474
b=0.1875
c=0.27272727
d=0.375
⓵ Write down your complete equation:
x + ¾ = 9/8
⓶ Solve the equation in order to find the value of “x”:
x + ¾ = 9/8
- ¾ - ¾
x = 9/8 - ¾
There a 3 simple steps to subtract fractions:
⒈ Make sure the bottom numbers (the denominators) are the same.
9/8 - ¾ → They don’t have the same denominator.
You need to multiply the top number and the bottom number of ¾ by 2 :
3 (x2) 6
—- = ——
4 (x2) 8
So now you are left with : 9/8 - 6/8
⒉ Subtract the top numbers (the numerators). Put the answer over the same denominator :
9 - 6 = 3 → ⅜
⒊ Simplify the fraction (if needed) :
⅜ → The fraction is already simplified.
⇨ Your answer is: x = ⅜
There you go! I really hope this helped, if there’s anything just let me know! ☻
Answer:
Group A: 9.56 Group B: 15.52
Step-by-step explanation:
Group A because it has fewer numbers and the mean is less.

is your formula
0.17=1.7e^{0.1t} 10% of 1.7 is 1.7*0.1=0.17
0.1=e^{0.1t}
ln(0.1)=0.1t
t= ~23 years
if I assume the values used are correct, it will take approximately 23 years for 10% to decompose.

Answer: 126.5 square cm</h3>
===================================================
Explanation:
Check out the diagram below. I've drawn a horizontal line to split the orange region into two parts: a triangle on top and a rectangle down below.
The triangle has base 11 cm and height 7 cm. The area is base*height/2 = 11*7/2 = 77/2 = 38.5 sq cm.
The rectangle has area 11*8 = 88 sq cm.
The total area of the entire orange figure is 38.5+88 = 126.5 square cm
