Question 11-(3 marks available)
1 answer:
Answer: 1080
Determine the values of b1, b2, and b3, the sides of the triangular base. Also determine the value of h, the height of the triangular base and l, the length of the prism (the length between the bases).
The sides of the triangular base are:
b1 = 13 in.
b2 = 14 in.
b3 = 15 in.
The triangular base is a right triangle, and so the height is one of our sides. We will use
h = 12 in.
The length of the prism is
l = 20 in.
total surface area = bh + (b1+b2+b3)*l
bh = 12*20 = 240
l * (b1+b2+b3) = 20*(13 + 14+ 15) = 840
TSA = bh + l * (b1 + b2 + b3) = 240 + 840 = 1080

Answer:
Step-by-step explanation:
part A:
okay so you saved $300 and choose to spend $50 a week
the 300 is positive and is the y-intercept since thats the amount of money you start with
and the 50 is negative because that is being spent and is the slope
so the equation is:
y = -50x + 300
part B:
the graph will be on the bottom
the (6, 0), aka the x-intercept, shows that in 6 weeks you will be out of money
the (0, 300), aka the y-intercept, shows that in the beginning of summer you have $300
part C:
the y-intercept is 300; it represents the amount of money you have in the beginning of the summer
