i think i have give a correct answer
Answer:
t = 640
Step-by-step explanation:
tickets are directly proportional to number of hours.
t =kh
we find K.
240 = 3k
we divide by 3 in both sides.
k = 80
we substitute K to find how many tickets.
t =80 × 8
t = 640
it doesn't matter if you chose any two, e.g., you would get the same answer even if you used 5 and 400, or 9 and 720
The rope tied to the tree will make a triangle.
The height of the triangle = 180cm
The base of the triangle = 200cm
to find how much rope you need, work out the hypotenuse using Pythagoras:
180^2 + 200^2 = 72400
√72400 = 269.0724809
This is the length of rope he needs, however you need to +30 as this is what he will need when he ties the rope:
269.0724809 + 30 = 299.0724809
299.0724809 is less than the 270cm of rope he has, so he would need more.
Answer:
m= -84
Step-by-step explanation:
Step 1- Multiply both sides by 7
42-m= 126
Step 2- Move constant to the right hand side and change its sign
-m= 126-42
Step 3- Subtract the numbers
-m= 84
Step 4- Change the signs on both sides of the equation
m= -84
