Part A: Connor is wrong, this is because the inequality 9x<27 means that 9x is LESS than 27. For example, if x was 17, it would mean 9 times 17 (153) which is WAAAY more than 27. Connor's statement is nonsense.
Part B: x could equal 2 or less. This is because anything over 2 will not fit with the inequality. (if x was 3 that would make it equal to 27 and that won't be right). 9 times 2 is 18 which is less than 27, so is 1 and so on :)
Answer:
Square 18.
Step-by-step explanation:
First, you subtract 4 from 24, and get 20, which you subtract 2 from to get your answer: 18.
Hope this helps!
Part A)
Using the Pythagorean theorem you can find the height:
17^2 = 8^2 + x^2
289 = 64 +x^2
x^2 = 289 - 64
x^2 = 225
x = √225
x = 15
The height is 15 cm.
Part B)
Area of the triangular side: 1/2 x 16 x 15 = 120 square cm.
There are two triangles so 120 x 2 = 240 square cm.
One side = 20 x 17 = 340
There are 2 sides so 340 x 2 = 680 square cm.
The bottom is 16 x 20 = 320 square cm.
Total cardboard needed: 240 + 680 + 320 = 1,240 square cm.
Answer:
30.2 - 13.7=n
Step-by-step explanation:
To get how far he ran you have to subtract 30.2 from 13.7 therefore giving you 16.5 which will be the total distance he ran after lunch.
