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.
Jorge did better on his test.
Step-by-step explanation:
It is difficult to say who scored better on the test because Jorge got less wrong but had less questions on his test, Ava got more wrong but has more questions but overall 17 out of 20 is a 85% when 20 out of 25 is 80%
$12*85%(the amount of the regular price that you pay)= <span>10.20 </span>
Answer: 8
Step-by-step explanation:
Pythagorean theorem - a^2+b^2=c^2
a^2+15^2=17^2
a^2+225=289
(subtract 225 from both sides)
a^2=64
(sq root both sides)
a=8
Answer:
5x<12
Step-by-step explanation:
Five times x is equally 5x fewer than is equally < # 5x<12
