5 0

Answer:

The first one

Step-by-step explanation:

when you are doing work with decimals the less numbers behind the decimal the bigger the decimal the more numbers the smaller the decimal based on that, 3550 is the biggest so that would go first. 13 is the next biggest and 0.3 is the same as 0.30 and there are less numbers after the decimal so that is the next biggest. 0.35 would go next because there are more numbers behind the decimal which makes it the smallest. I hope this helps :P

The formula of an area of a circle:

A=\pi r^2

r - radius

Circle A:

radius = 4 ft. Substitute:

A_A=\pi(4^2)=16\pi\ ft^2

Circle B:

radius = 9 ft. Substitute:

A_B=\pi(9^2)=81\pi\ ft^2

The ratio:

If f(x) = 3x - 1 and g(x) = x + 2, find (f+ g)(x).
Volgvan

Answer:

4x+1

Step-by-step explanation:

Since you're finding (f+g) (x), it means you are adding f(x) and g(x) together.

so you add: (3x-1) and (x+2)

combining like terms, you get 4x and 1, which means (f+g)(x)= 4x+1

Alenkinab [10]

Answer:

(728, 748)

Step-by-step explanation:

You need the Z value which for 95% confidence interval is 1.96. The mean is $738 and the standard deviation of $41.

X-Zs/\sqrt{n} \\ X+Zs/\sqrt{n}

Therefore we can calculated the confidence interval

738-1.96\cdot{41}/\sqrt{61} =738-10.3

738±10.3

The interval is (728,748)
