Glenda and Fiero are at a restaurant eating meal that costs $30. They have a discount coupon that gets them 10% off the cost. If

yaroslaw [1]

The cost of meal = $$30$

The tip to the waiter = $8%$ %

Discount = $10%$ %

Cost = $30 + 0.08 * 30 - 0.1 * 30$

Cost = $30(1 + 0.08 - 0.1)$

Cost = $ $$29.4$ 0

Dirk opened up a savings account with $600. At a yearly interest rate of 5 percent that is compounded monthly, how much interest

gladu [14]

Answer:

Hence final answer is $15.17

Step-by-step explanation:

Given that Dirk opened up a savings account with $600.

So P=$600

"At a yearly interest rate of 5 percent"

Means r=5% = 0.05

"compounded monthly" means n=12

i= monthly rate of interest = r/n=0.05/12

"how much interest will Dirk earn in six months." means find Interest when time is 6 months

Plug these values into compound interest formula:

$A=P\left(1+i\right)^t$

$A=600\left(1+\frac{0.05}{12}\right)^6$

$A=600\left(1+0.00417\right)^6$

$A=600\left(1.00417\right)^6$

$A=600\left(1.02528228828\right)$

A=615.169372966

which is approx

A=615.17

Now interest earned will be difference of A and P

Interest =A-P=615.17-600=$15.17

Hence final answer is $15.17

Find the height of the triangle. A=2c^3+16, b=c+2

larisa [96]

A is an angle since it is a capital letter and both b and c are sides. We also know one height of the triangle could equal b times sinA. So my height=(c+2)(sin(2c^3+16)), depending on which height we are looking for, in this case I am using c as the base.
