Step-by-step explanation:

Equation is 6d (6 • d)

Actual Question:

c = 6d

Let d = 7.89

c= 6 (7.89)

c = 47.34

Michael would have spent a total of $47.34.

Answer:

Equation: c = 6d

Total cost: $47.34

Step-by-step explanation:

Equation:

c = 6d

Where c is the total cost and d is the price a book

In order to find the total cost, you must multiply the price of something by the number of items you bought; therefore the equation above accurately represents the problem.

Substitute:

c = 6d

c = 6(7.89)

Multiply:

c = 6(7.89)

c = 47.34

In conclusion, Michael would spend $47.34 on 6 books.

Hope this helps :)

Find the values of the unknown angles marked with letters. 50 points!!!!!!!
IceJOKER [234]

Answer:

  • a = 115°, alternate interior angles are congruent
  • b = 70°, same as above
  • c = 180° - 115° = 65°, angles forming a straight angle are supplementary
  • d = 180° - 70° = 110°, same as above

The principal represents an amount of money deposited in a savings account subject to
RSB [31]

Step-by-step explanation:

So the general formula for compound interest is A = P(1+\frac{r}{n})^{nt} where t is typically time in years, and n is how many times it's compounded per year. But in this case it's only compounded 1 time per year so the equation is just A = P(1+r)^t. in this case P is the principal amount, r is the interest, and A is the final amount. So the 5% interest rate becomes 0.05 by dividing by 100 to convert it into decimal form and the principle amount of 11,000. This gives you the formula A = 11000(1.05)^t. This is the answer to the first question where t is the time in years. When it says "Find interest earned" I'm a bit confused, is it giving you x amount of years where you have to calculate the interest earned or does it want a general equation? Because the general equation would be the final amount - the principle amount which calculates the difference. So the equation for interest earned would be 11000(1.05)^t-11000. To calculate the amount of money after 5 years you simply plug in 5 as t. this gives you the equation 11000(1.05)^5 \approx 11000(1.276) \approx 14,039.10
