We see a right triangle here.
Use the Pythagorean Theorem:
a^2+b^2=c^2
a & b=legs
c=hypotenuse
a^2+15^2=20^2
a^2+225=400
a^2=175
a=13.2287565553
a=13.2
The missing side is 13.2cm

You are purchasing books summer reading for $4.50 each. Part A: Your total cost, C, depends on,The input is,and the output is,Pa

Crazy boy [7]

Answer:

Part A) see the explanation

Part B) $C(12)=\$54$

Step-by-step explanation:

Part A)

we know that

A relationship between two variables, x, and C, represent a proportional variation if it can be expressed in the form $k=\frac{C}{x}$ or $C=kx$

Let

C ---> is the total cost (represent the output or dependent variable)

x ----> is the number of books (represent the input or independent variable)

In this problem

we have a proportional relationship between the variables x and C

Part B) we know that

The linear equation is given by

$C=kx$

The constant of proportionality k is the same that the slope or unit rate of the linear equation

In this problem the constant k is given

$k=\$4.50\ per\ book$

$C=4.50x$

For x=12 books

substitute in the equation and solve for C

$C=4.50(12)=\$54$

In function notation

$C(12)=\$54$

The glee club has a set of 48 classical cds and a set of 42 show tune cds. each set can be divided equally among the club member

Hoochie [10]

We have to find the GCF (Greatest Common Factor) of 48 and 42 here...

Factors of 48:
1,2,3,4,6,8,12,16,24,48

Factors of 42:
1,2,3,6,7,14,21,42

The largest common factor of these two numbers is 6.

So, there can be a maximum of 6 members in the club..

Hope this helped!

Solve for x<br><br> 1/5(2/3x - 1/2) > x + 1/3

taurus [48]

Answer:

x<-11/26

Step-by-step explanation:

1/5(2/3x-1/2)>x+1/3

2/15x-1/10>x+1/3

2/15x-x>1/3+1/10

-13/15x>11/30

x<(11/30)(-15/13)

x<-11/26
