Answer:
0.3
Step-by-step explanation:
30% out of 100% is 30/100 or 3/10. 3/10 as a decimal is 0.3.
If this helped I would appreciate it if you marked me Brainliest. Thank you and have a nice day!
First, you subtract 2x on both sides
divided on both sides by -3
Hi there! :)
Answer:
(a) ≈ 3.61 cm.
(b) = 2.77 cm².
Use the Pythagorean theorem to solve for the side-length of DC. Let "s" represent the side-lengths:
s² + s² = 26
2s² = 26
Divide both sides by 2 to simplify:
s² = 13
Take the square root of both sides:
s = √13 ≈ 3.61 cm.
------------------------------------------------------------------------------------------
Calculate the shaded region by subtracting the area of the arc from the area of the square. DC represents the radius of the circle that the arc is apart of. Therefore:
Area of arc AC = 1/4 (πr²)
Solve for the area:
AC = 1/4 (π · (3.61)²)
AC = 1/4 (40.92)
AC = 10.23 cm²
Subtract this area from the area of the square (A = s²)
A = (√13)²
A = 13 cm²
13 - 10.23 = 2.77 cm²
Therefore, the solutions are:
(a) ≈ 3.61 cm.
(b) = 2.77 cm².
Answer:
a = P( 1+R)^T
a = 10(1+0.4)^T
a = 10(1+0.4)^5
a = 53.7824
Step-by-step explanation:
input 5 for T
growth rate = 40%
0.4 = 40%
you add 1 when its a growth and subtract 1 when decay
A=58 in^2
l= 10 in
A = w*l
58 = w*10
w=58/10
w=5,8 in
hope helped
