12) Find the sum, S7, for the geometric series (1 + 5 + 25+ --- + 15625).

vfiekz [6]

Answer:

Find the (r) between adjacent members

a2/a1=+25/5=5

a3/a2=+125/+25=5

a4/a3=+625/+125=5

a5/a4=+3125/+625=5

a6/a5=+15625/+3125=5

The ration (r) between every two adjacent members of the series is constant and equal to 5

General Form: a

Answer:

The number of students whom should be admitted is 377.

Step-by-step explanation:

Given:

College has space for 580 students.

The college estimates that 65% of the students who are admitted will attend the college.

Now, to find the number of students whom should be admitted.

Space for total number of students = 580.

Percentage of the students who are admitted = 65%.

Total number of students whom should be admitted = 65% of 580.

$=\frac{65}{100}\times 580$

$=\frac{37700}{100}$

$=377.$

Therefore, the number of students whom should be admitted is 377.

10) What is the solution to the system of equations shown below?

kkurt [141]

Answer:

B

X= 7.5

Y= -5

Step-by-step explanation:

In systems of equations, the goal is to add both of the equations together so it cancels one of the variables and you solve for that variable. Before you add they together, you multiply one of the equations by a negative number so when you add them together one of the numbers with x or y cancel.

I will upload a picture showing my work.
