The answer is $380.
First find the area of the triangle. The area (A) of the triangle with base b and height h is:
A = b * h / 2
The width of the floor is the base of the triangle: b = 8 ft
The extension into the area is the height of the triangle: h = 10 ft
A = 8 * 10 / 2
A = 80/2
A = 40 ft²
The cost is $9.50/ft². So, the price of the white marble section is:
40 ft² * $9.50/ft² = $380
Answer: The answer would be B. 5x - 10
Step-by-step explanation: I’m positive because I will only answer questions if I’m 100% sure. Hope you do well on your test or quiz!! Good luck!
Consider, cost of one bag of cotton candy=x
cost of one souvenir cup = y
Now, 4x+2y=36 , 2x+y=18------(I)
7x+3y=59-------(ii)
in (I), y=18-2x, substitute it in (ii),
7x+3(18-2x)=59
7x+54-6x=59
x=5, substitute it in equation (I),
2(5)+y=18
y=8....ANS
Y=mx+b
m=slope
b=y-intercept
y=-4x+b
Plug in the coordinate in place of x and y (-2,1)
1=-4(-2)+b
1=8+b
Subtract both sides by 8 to isolate B
b=-7
Final answer:
<span>y = −4x − 7
