Answer:
and $475 deposited into the account on her birthdays by her 18th birthday.
Step-by-step explanation:
It is given that, on Gabriela’s first birthday, her parents gave her a $50 savings account.
Initial term : 
On every birthday after that her parents added to the account, increasing the amount they deposited by $25 each year.
Common difference : 
It forms an AP: 50,75,100,...
nth term of an AP is

Substitute
and
in the above formula.

It represents the amount deposited into the account after n birthdays.
We need to find the amount by her 18th birthday.
Put n=18 in the above equation.




Therefore, $475 deposited into the account on her birthdays by her 18th birthday.
Step-by-step explanation:
To do Order of Operations, we need to go with the order of the formula, PEMDAS.
P= Parenthesis
E= Exponents
M= Multiply (Whatever Comes First in Equation: M and D)
D= Divide
A= Addition (Whatever Comes First in Equation: A and S)
S= Subtraction
---------------------------------------------
So, we need to start with parenthesis, there aren't any, so we move on to Exponents.
There are no Exponents either, so we start with division, then multiplication.
(We always have to go left to right).
So,
-9 - 6 + <u>8 / -4</u> x -2
-9 - 6 + <u>-2 x -2</u>
-9 - 6 + 4
Our problem is:
-9 - 6 + 4
We do subtraction, then addition. (Left to Right)
<u>-9 - 6 </u>+ 4
<u>-15 + 4</u>
-11.
Therefore, the answer is -11.

Answer:

Step-by-step explanation:
As we can see in the figure that
The R, S, T ,and Q are the points on the circle O.
Also
The measurement of the circular arc is equivalent to the measurement of the angle at the center of the arc
So by this



m(major arc RQ) = m(∠QOR)
So,

And as we know that
All angles sum = 360°
Therefore
