Answer:

Step-by-step explanation:

What we know

total sum of angles = 540 deg

3/2 b cam also be written as 1.5b degrees.

So 1.5b + (b+45) + (2b - 90) +90 = 540

Step 1 -- get rid of parenthesis

1.5b + b + 45 +2b -90 +90 =540

Step 2 -- combine the like expressions

4.5b + 45 = 540

Step 3 -- subtract 45 from both the sides

4.5b = 495

Step 4 -- divide 4.5 from both the sides

b = 110 ----- not the right answer

Thats not right okay im sorry

but i guess if it is not 110 it should be 100, 90 etc.

90 = b is correct

Sir Ving Spoon earned $5,436 on his $7,550 certificate of deposit. If he had the CD for 12 years, what simple interest rate did

Lilit [14]

6% or 0.06 is the simple interest rate the bank pays him.

Step-by-step explanation:

Sir Ving Spoon earned $5,436 on his $7,550 certificate of deposit.

From this given information,

It can be determined that the Principal amount is $7550 and the interest amount is $5436.

The CD is for 12 years. Therefore, the number of years is 12.

To find the interest rate (r) :

Using the simple interest formula,

Interest = P×r×t

where,

P is the principal amount = $7550
r is the rate of interest.
t is the number of years = 12

⇒ 5436 = 7550 × r × 12

⇒ 5436 = 90600 × r

⇒ r = 5436 / 90600

⇒ r = 0.06

Multiply by 100 to represent in rate %

⇒ r = 0.06 × 100

⇒ r = 6%

∴ 6% or 0.06 is the simple interest rate the bank pays him.
