Answer:
25
Step-by-step explanation:
since the angle in question is across from angle 70, they are congruent. You set up the equation
70=20+2p
50=2p
25=p
 
        
             
        
        
        
5.6775 milliliters 
Explanation: First ask how many liters are in one gallon(3.79) then split that number in half (1.895)and add to that to 3.79 and your final answer is 5.6775
        
             
        
        
        
 Answer:
   There are 2 nickels and 6 dimes.
Step-by-step explanation:
Nickels:  x
  Dimes:  y
Constraints:
   0.05x + 0.10y = 0.70
    x + y = 8                   ===>  -0.05 * (x + y = 8)  ===>   -0.05x - 0.05y = -0.4
Add the two equations to eliminate x variable:
   0.05x + 0.10y = 0.70
  -0.05x - 0.05y = -0.4
 _________________
                 0.05y = 0.3         ===>    y = 6
Substitution to find x:
   x + y = 8 
   x + 6 = 8 
   x = 2
There are 2 nickels and 6 dimes.
 
        
             
        
        
        
Linear regression line y=2.1x+130 predicts sales based on the money spent on advertising.
Linear regression represents the relationship between two variables. the value of y depends on the value of x.
x represents the dollars spent in advertising and y represents the company sales in dollars.
We need to find out sales y when $150 spends on advertising.
Plug in 150 for x and find out y
y = 2.1 x + 130
y = 2.1 (150) + 130
y= 445
The company expects $445 in sales
