K=2
- A'=2(2.5)=(4,10)
- B'=2(1,2)=(2,4)
- C'=2(3,1)=(6,2)
Translation of 2 units left means change in x
- A''=(4-2,10)=(2,10)
- B"=(2-2,4)=(0,4)
- C"=(6-2,2)=(4,2)
Translation of 1 units up means change in y
- A'''=(2,10+1)=(2,11)
- B'''=(0,4+1)=(0,5)
- C'''=(4,2+1)=(4,3)
Answer:
its 4
Step-by-step explanation:
cam got it wrong because cam should have used -2 as his division since the factor was x-3 to be specific in the fator x is a positive but the 2 is a negative but he put a positive 2
Answer:
24 gear.
Step-by-step explanation:
It is given that 
.
Gear A = 36 teeth
Gear C = 16 teeth
Let gear B have x teeth.
On cross multiplication we get
Taking square root on both sides.
Therefore, gear B have 24 teeth.
Answer:
Step-by-step explanation:
Take a. for example. Use the largest denominator and divide it by the smaller one, in this case 12 and 3. So 12/3=4. Multiple your product with the denominator. 4 x 1 = 4. Therefore 1/3 = 4/12.
Use that method for all of the questions. I hope you understand. Good luck :) !!
Answer:
8 to 40, 2/10, 6:30
Step-by-step explanation:
8:40 -> 8 / 8 : 40 / 8 -> 1:5 WORKS
3:20 -> 3 / 3 : 20 / 3 -> Doesn't work
2:10 -> 2 / 2 : 10 / 2 -> 1:5 WORKS
6:30 -> 6 / 6 : 30 / 6 -> 1:5 WORKS
2:9 -> 2 / 2 : 9 / 2 -> Doesn't work
5:20 -> 5 / 5 : 20 / 5 -> 1:4 -> Doesn't work
Answer: 8 to 40, 2/10, 6:30
