. which statement is true about her answer?

Her answer is not correct because the sum cannot be less than either addend.

Step-by-step explanation:

The given numbers are

and

Alaina evaluated and got an answer of . We need to check whether she is correct or not.

The sum of both numbers is

The correct answer is .

If two positive numbers are added then the sum is always greater than each number.

Therefore, her answer is not correct because the sum cannot be less than either addend.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
