Is that number times itself
Answer:
1.75 meters² or 175 centimeters²
Step-by-step explanation:
Step 1: Find Area of the Base.
- Base is a square with dimensions of 7cm by 7cm
-
Step 2: Find the Area of the Triangles.
- Each triangle has a base of 7cm and a height of 9cm.
- 7 x 9 = 63, and 63/2 = 31.5
- 31.5 x 4 = 126 cm²
Step 3: Add the areas together.
-
- 175 cm²
Thus, the surface area is 1.75 m^2 or 175 cm^2.
30x9.2= 276 miles
9.2x3.15=$28.98
So the car can drive 276 miles if you put $28.98 of gas in it.
I think the answer to this question is 112
Answer:
Step-by-step explanation:
The first rule is that 2 of the sides must be bigger than the third.
4 and 7 makes 11 which is not bigger than 12, so A is not an answer.
5 + 7 = 12 That does not exceed 12, so the second one is not an answer
12 12 and 7 works perfectly. It makes an isosceles triangle. Any two of the three sides added together is larger than the third side.
If you put 19 20 or 21 into what you think might make a triangle, you would be incorrect. 12 and 7 makes 19. 19 is too large because 12 and 7 will lie flat on 19. No triangle works.
So only 12 works.
In short, 5<x<19 will create a triangle. Anything outside that inequality will not.
