Answer:
step 1: x+50+4x=90
the angle of a right-angled triangle is 90 degrees, therefore if we add everything together ,we could work out what x is. 
step 2: x+50+4x=90
                   x+4x=50 
                       5x=50
                         x=10 
then you solve the equation, x is 10
 
        
             
        
        
        
The line plot that correctly represents the given data set is: line plot C.
<h3>What is a Line Plot?</h3>
On a line plot, the frequency of a data points is represented using "x" as many times as the data points appear in the data set.
The data point with the highest frequency is 11¼ which is also 11⅛. And they appear 4 times in the given data set.
So, the line plot that correctly shows the data is: line plot C.

Answer:
y = 2x - 2
Step-by-step explanation:
y= mx+b 
m= slope
b= y-intercept (point on line where x= 0.... or the point where the line hits the y-axis)
Determine slope by using slope formula or by counting boxes
By counting boxes, you can see that each point is 2 units up, 1 unit right (2/1)
the slope is 2 
the point where the line is touching the y-axis is (0, -2) 
m = slope = 2
b  = y-intercept = -2
y = 2x + (-2) OR y = 2x -2
 
        
             
        
        
        
Answer:
7959.83
Step-by-step explanation:
A = P ( 1+r/n)^ nt
Where A is the amount in the account
P is the principal
r is the rate 
n is the number of compoundings per year
t is the years
A =3000 ( 1+.10/2)^ 2*10
A =3000 ( 1+.05)^ 20
    =7959.83
