Answer:
10 is correct
Step-by-step explanation:
2(4+1)
2(5)
=10
Solution:
<u>First, let's find the surface area of the triangular prism.</u>
- 2(1/2 x 8 x 12) + 2(10 x 6) + (12 x 6) = Surface area of triangular prism
- => (8 x 12) + 2(60) + (72) = Surface area of triangular prism
- => (96) + 120 + 72 = Surface area of triangular prism
- => 96 + 192 = Surface area of triangular prism
- => 288 ft² = Surface area of triangular prism
<u>Now, let's find the surface area of the rectangular prism.</u>
- 2(18 x 9) + 2(6 x 9) + 2(6 x 18)
- => 2(162) + 2(54) + 2(108)
- => 324 + 108 + 216
- => 2(324) = 648 ft²
<u>Now, add both the surface areas to find the surface area of the figure.</u>
- 288 + 648 = Surface area of figure
- => 936 ft² = Surface area of figure
The surface area of the figure is 936 ft².
Answer:
A) 5.50x + 10y ≤ 800
B) yes
C) no
D) 80 pull buoys and 35 kick boards
Step-by-step explanation:
A) The sum of costs must not exceed the budget:
5.50x +10.00y ≤ 800
__
B) 5.50(0) +10.00(50) = 500 ≤ 800 . . . . . yes, the coach could buy these
__
C) 5.50(125) +10.00(25) = 937.50 > 800 . . . no, they cost too much
__
D) The point (80, 35) is in the solution space. The coach could buy 80 pull buoys and 35 kick boards.
Step-by-step explanation:
the y intercept is where 0= x
(0,y)
m is 5
