Sylvia bought a 6-month $1900 certificate of deposit. at the end of 6 months, she received a $209 simple interest. what rate of interest did the certificate pay? show all of your work.

Step-by-step explanation:

We are given that Sylvia bought a 6-month $1900 certificate of deposit.

Time of deposit = 6 months of a year.

Let us assume rate of interest = R% per year.

Formula of simple interest I = PRT, where P is the bond amount, R is the rate of interest per year and T is the time in years.

Plugging values I=209, P= 1900, R= R%  and T= in above formula, we get

209 = 1900×R×

On simplifying right side, we get

209=950R

Dividing both sides by 950, we get

R= 0.22

Converting 0.22 into % by multiplying by 100, we get 22%.

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
