Answer:
108
Step-by-step explanation:
4−22+135−9
=−18+135−9
=117−9
=108
B and C are correct, A and D are incorrect
Answer:
There are two answers, either of which would work
- 26°, 26° and 128°
- 26°, 77° and 77°
Method:
An isosceles triangle has 2 of the same sides so there are two possible answers:
1) 26° is one of the angles which is the same as another. 26° × 2 = 52° and since there are 180° in a triangle the other angle is 180° - 52° which is 128°. This would make the angles 26°, 26° and 128°
2) 26° is not one of the angles which is the same as another. Since there are 180° in a triangle, the other angles would both be 2 ÷ (180° - 26°) which is 77°. This would make the angless 26°, 77° and 77°
Answer:
3rd Answer =Option A is the Correct Answer
Step-by-step explanation:
Answer:
side of 6.124 ft and height of 3.674 ft
Step-by-step explanation:
Let's s be the side of the square base and h be the height of the rectangular box.
The base and the roof would have an area of
and cost of

The sides would have an area of 4sh and cost of 4sh*2.5 = 10sh
So the total cost for the material is



The volume of the shed has the following formula

To find the maximum value for V, we can take its first derivative, and set it to 0




h = 45/s - 0.6s = 3.674 ft
