Okay well the starting is 28 dollars, right. But since there is a 20 percent discount, you have to turn 20% to a decimal. That means moving the decimal sign twice to the left to make it .20. From the it would be .20*28, that should equal 5.6. Now, that 5.6 is the amount you have to take away, it is the price of the sale. From then, you subtract which is 28-5.6 which should be 22.4. From that 22.4 you now take away two dollars and then it should be 22.4-2 which should be 20.4. Now that is your answer, 20.4.
Answer:
26.1799
Step-by-step explanation:
Area equals 
r² = 5² = 78.5398
The two shaded areas are each 60°. That makes 120°. 120°is 1/3 of 360°
78.5398÷3=26.1799
Answer:
Applying Pythagorean theorem:
r = sqrt(3^2 + (14/2)^2) = sqrt(9 + 49) = sqrt(58) = ~7.6 cm
Hope this helps!

6 Pallets per hour.
If there are 9 that need to be done in 1.5 hours, we have 9 in 90 minutes. If we divide that by 9, we get 1 every 10 minutes. If we multiply that to get an hour, we get 6 done in 60 minutes.

The rewritten equation is:
" - 3x² + 30 + 225 = 0 " ;
which is ultimately simplified to:
" x² − 10 − 75 = 0 " .

The number of days is: "15 days" .

Explanation:
______________________________________________
Given:
h(x) = - 3x</span>² <span>+ 30 + 225 ;
Rewrite as: " </span>- 3x² + 30 + 225 = 0 " ;
__________________________________________________________
Multiply EACH SIDE of the equation by "-1" ; to get rid of the "-3" ;
-1 * {- 3x² + 30 + 225 = 0} ;
to get: " 3x² − 30 <span>− 225 = 0" ;
Divide EACH SIDE of the equation by "3" ; to simplify; since:
"3", "30", and "225" are divisible by "3" ;
{</span>3x² − 30 − 225} / 3 = 0 / 3 ;
to get:
______________________________________
" x² − 10 − 75 = 0 " ;
______________________________________
Let us factor:
-15 + 5 = -10 ;
-15 * 5 = -75 ;
_______________________________________
Rewrite as:
(x − 15) (x + 5) = 0 ;
x = 15; and x = -5 ;

The number of days cannot be "negative value"; so we stick with:
"x = 15 days"
