Miss Parker invested a certain amount of money at 9.2% interest and another amount, $700 more than the first, at 10.4%. If the total annual interest is $425.60, how much money is in each investment

$1800 and $2500

Step-by-step explanation:

Let he invested a total of  $P and$( P+700) in each investment so according to question

9.2*P*1+10.4*(P+700)*1= 42560

19.6P+ 7280= 42560

19.6P = 42560-7280= 35280

P=$ 1800

So, he invested $1800 and $2500 respectively.

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
