The Three angles of a triangle have measures 7x+6,10x-8 and 5x+3.What is the measure of the smallest angle?
g100num [7]

Answer:

43 15/22 degrees

Step-by-step explanation:

The three angles add to 180 degrees

7x+6 +10x-8 + 5x+3 = 180

Combine like terms

22x +1 = 180

Subtract 1 from each side

22x +1-1 =180-1

22x = 179

Divide each side by 22

22x/22 = 179 /22

x =179/22


The smallest angle is

5x+3

5(179/22) +3

895/22 +3

40 15/22 +3

43 15/22 degrees

If interest is compounded every 3 months, how often is it compounded?
Mamont248 [21]

Answer:

c. quarterly

Step-by-step explanation:

To start with 1 year is equal to twelve months

3months out of 12 months will be;

3/12= 1/4

Here it is compounded quarterly and n=4  where n is the number of compoundings a year.

Lets study the compound interest formula;

A=P(1+\frac{r}{n} )^{nt}

where;

A=The ending amount

P=Starting amount

r=rate of interest expressed as a decimal

n=number of compoundings a year

t=total number of years

The number of compoundings in any one year  can be an interest compounded  yearly where n=1, semi-annually with n=2, quarterly where n=4, monthly where n=12, weekly and n=52 and finaly daily with n=365.
