Answer:
Change in one week is more than the change in the next week
Step-by-step explanation:
Change in Sara's savings account balance in one week =
Change in Sara's savings account balance in next week =
Tens digit in 34 = 3
Tens digit in 67 = 6
If we compare the tens digit of 34 and 67, we get
So,
On multiplying both sides by -1 , we get .
{ We know that negative sign changes sign of inequality }
So, we get change in one week is more than the change in the next week .

Step-by-step explanation:
Cinematics
When an object moves at a constant speed, it can be computed as
Where x is the distance traveled and t the time needed to complete it at the constant speed v
If we wanted to compute t from the equation above, then
Elia rode her bicycle from her house to the beach at 18 km/h and then from the beach to the park at 15 km/h, taking 1 hour in the whole travel, each distance being equal. If we call b as the number of hours it took Elia to ride from her house to the beach, and p the number of hours it took her to ride from the beach to the park, then we can compute
The question doesn't ask for something in particular, so I'm helping you by solving the complete problem. We know the total time is 1 hour, so
Replacing b and p
Multiplying by 90
Simplifying and solving for x
We finally compute b and p
The correct answer is:
1250 skiers and 2500 snowboarders.
Explanation:
The ratio is 1:2. We are told that more snowboarders buy season tickets than skiers; this means the ratio is skiers/snowboarders.
Let x be the number of skiers that bought season tickets. Since 1250 more snowboarders bought season tickets, this means the number of snowboarders would be represented by x+1250.
We can use the ratio to set up a proportion:
Cross-multiply:
(x+1250)(1) = x(2)
x+1250 = 2x
Subtract x from each side:
x+1250-x = 2x-x
1250 = x
This means the number of skiers is 1250.
The number of snowboarders would then be 1250+1250 = 2500.
