<h2><u>ISOSCELES TRIANGLE</u></h2>

An isosceles triangle is a triangle that has two sides of equal length. In this exercise, we see small lines on two of the sides. This means that those sides are equal.

‎      ‏‏‎

Equalize the expressions:

<h3>6x - 23 = 4x + 9</h3>

Add 23 to both sides of the equation:

6x - 23 + 23 = 4x + 9 + 23

‎      ‏‏‎‎      ‏‏‎‎    6x = 4x + 32

Substract 4x from both sides:

6x - 4x = 4x - 4x + 32

    ‏‏‎‎  2x = 32

Finally, divide both sides by 2:

\mathsf{\dfrac{2x}{2} = \dfrac{32}{2}}

\large{\boxed{\mathsf{x = 16}}}

‎      ‏‏‎

Now, let's find the measures of the angles:

  • (6x - 23)° = 6(16) - 23 = 96 - 23 = 73°
  • (4x + 9)° = 4(16) + 9 = 64 + 9 = 73°

‎      ‏‏‎

Remember: The sum of the three angles of any triangle is equal to 180 degrees. Let's find the measure of the angle Y:

73° + 73° + Y = 180°

146° + Y = 180°

Y = 180° - 146°

Y = 34°

‎      <u>‏‏‎</u>

<h3><u>Answer</u>. m∠Y = 34°</h3>

‎

sonja wants to have $14000 in 13 years. calculate how much she should invest now at 6% interest, compounded semiannually in orde
mariarad [96]
She should invest $6491.73.

The equation we use to solve this is in the form
A=p(1+\frac{r}{n})^{nt}, 
where A is the total amount in the account, p is the principal invested, r is the interest rate as a decimal, n is the number of times per year the interest is compounded, and t is the amount of time.

A in our problem is 14000.
p is unknown.
r is 6% = 6/100 = 0.06.
n is 2, since it is compounded semiannually.
t  is 13.

14000=p(1+\frac{0.06}{2})^{13*2}&#10;\\&#10;\\14000=p(1+0.03)^{26}&#10;\\&#10;\\14000=p(1.03)^{26}&#10;\\&#10;\\\text{Dividing both sides by }1.03^{26}\text{, we have}&#10;\\&#10;\\\frac{14000}{1.03^{26}}=\frac{p(1.03)^{26}}{1.03^{26}}&#10;\\&#10;\\6491.73\approx p

Trisha had the following seven distances (in feet) in the triple jump.
butalik [34]
The range of a data set is the greatest value minus the smallest value.

The greatest value here is 32, and the smallest value is 27:

\sf Range=32-27=\boxed{\sf 5}
