Explanation: The idea is to draw a Venn Diagram and find the intersection. We have one circle of 70 and another with 40. When we add the two circles plus the 10 students who joined neither, we should get 100 students.

Step-by-step explanation:

Consider the figure shown below. Find the value of each variable mentioned in the figure below​
Solution 1
  • a = 26, b = 64, c = 42


The measure of an inscribed angle is half the measure of the intercepted arc:

  • a = 52/2 = 26,
  • c = 84/2 = 42.

Angles a and b sum to a right angle since inscribed between the tangent and diameter.

Then we have:

  • a + b = 90
  • 26 + b = 90
  • b = 90 - 26
  • b = 64

The population of city A is 23.5% of city B and the population of city B is 51% of city C. If city C has 9.89 million people, which of the following is the closest approximation of city A's population in millions?
0.95 million
1.2 million
1.25 million
1.3 million
1.42 million
Solution 1

The required closest approximation of city A's population is 1.185 million.

What is percent?

Percentages  are basically divisions where the denominator is 100. To show that a number is a percent, we utilize the percent image (%) close to the number. For instance, on the off chance that you got 75 inquiries right out of 100 on a test (75/100), you would have scored 75%.

According to question:

We have, city A is 23.5% of city B

A/B = 235/1000 = 47/200 = (B)47/200-----------(1)

and, city B is 51% of city C.

B/C = 51/100

B = (51/100)×9.89 = 5.0439 million

As C = 9.89 million

Put the value of c in equation (1)

A =  (5.0439)47/200 = 1.185 million

Thus, required population of city A is 1.185 million.

Derrick deposited $700 in a savings account that pays 2.5% simple interest on a quarterly basis. After the initial deposit, he did not make any deposits and withdrawals. How many years ago did he invest the money if his current balance on the account is $980?
Solution 1

The required number of year at 2.5% simple interest on a quarterly basis is 4%.

What is simple interest on quarterly basis?

if the interest rate is 8% each year, however the estimation being referred to requires a quarterly financing cost, then, at that point, the significant loan cost is 2% per quarter. The 2% per quarter is comparable to a straightforward loan fee of 8% each year

According to question:

We have,

Interest in 3 months = 2.5%

So, interest in one year = 4(2.5%) = 10%

Principle amount = $700

Final amount = $980

To calculate number of years,

total interest = 980 - 700 = $280

Let number of years be t.


$280/t = 10% of $700

t = $280/$70 = 4 years

Thus, required years 4.

The coupon rate of a bond determines the percentage of interest earned on the bond each year. Samantha purchased a five-year municipal bond for $600. After the bond matured five years later, she had received a total of $720 in principal plus interest payments. What is the coupon rate of Samantha's bond?

Explain coupon rate of bond.

The coupon rate is the annual income an investor can expect to receive while holding a particular bond. It is fixed when the bond is issued and is calculated by dividing the sum of the annual coupon payments by the par value. At the time it is purchased, a bond's yield to maturity and its coupon rate are the same.c

According to question:

We have,

principal amount = $600

Amount after five year = $720

Interest of five year = $(720 - 600) = $120


Interest of one year = $120/5 = $24


Coupon rate = ($24/600)×100 = 4%

Thus, required coupon rate is 4%.

We have,

Amount of four year = $1200

simple interest = 10%

Let loaned amount is x


interest of four year =×4 x×10/100 = 4x/10


x + 4x/10 = $1200

14x/10 = $1200

x = $12000/14

X = $857 (appox)

Thus, the required loaned amount is $857.
