Answer:
=153 in^2
Step-by-step explanation:
We have a rectangle and a trapezoid
We can add the areas together
The area of the rectangle is
A = l*w where l =16 and w =3
A = 16*3 = 48 in^2
The area of the trapezoid
A = 1/2 (b1+b2)*h where b1 =16, b2=5 and h = 10
A = 1/2 (16+5) *10
= 1/2 (21) *10
=105 in^2
Then we add the areas together
A total = A rectangle + A trapezoid
A total = 48+ 105
=153 in^2
The one that is in vertex form is
x^2-4x+4
To solve this problem, we can set two equations.
Let x be the cost of coffee and y be the cost of latte.
Two coffees and one latte: 2x + y = 10.50
y=10.50 - 2x ...(1)
Three coffees and two lattes: 3x + 2y = 17.00...(2)
Put (1) into (2), we have:
3x + 2(10.50-2x) = 17.00
3x + 2(10.50) - 2(2x) = 17.00
3x + 21 - 4x = 17
Put the unknown to one side:
3x -4x = 17 - 21
-x = -4
When there are negative numbers on both sides, we can take the negative signs away:
x= 4
Therefore, cost of one coffee is A. $4.00.
