Complementary is when the two angles add up to 90 degrees.
Supplementary is when the two angles add up to 180 degrees.
To find a complementary angle do 90 minus the given angle.
To find a supplementary angle do 180 minus the given angle.
The sum of tax and discount will given by:
(15+7.25)%
=22.25%
Total percentage of the total cost will be:
100+22.25%=122.25%
the selling price of the court will be:
122.25/100×275
=4336.187
The answer is 4336.20
Answer:
x^2 + 8x + 16
Step-by-step explanation:
(x + 4) (x+ 4) multiply x by x and x by 4.
x^2 + 4x
Then multiply 4 by x and 4 by 4.
4x + 16
Then combine like terms.
x^2 + 4x + 4x +16
x^2 + 8x + 16
Answer:
Part 1) The maximum number of pounds of regular coffee that you can buy is 7.5 pounds.
Part 2)
Step-by-step explanation:
Part 1)
Let
x-----> the number of pounds of regular coffee
we know that
The inequality that represent the situation is
Solve for x
Divide by 2 both sides
The maximum number of pounds of regular coffee that you can buy is 7.5 pounds.
The solution of the inequality is the interval ------> (-∞,7.5]
but the number of pounds cannot be a negative number
therefore
The solution is the interval -----> [0,7.5]
see the attached figure
Part 2) we have
Adds m and n
Group terms that contain the same variable
Combine like terms
Answer:
(1,7)
Step-by-step explanation:
SImply replace x by (1) in the expression to find the value of h:
h(1) = 4 (1) + 3 = 4 + 3 = 7
so for x = 1, h is 7 , which is written as: (1, 7)
