Help me to solve problems..
3. Ballet has an even number of classes a day. 70 / 7 = 10
I'm sure you can finish this one now.
6. Since there are 35 modern classes a week, there must be 5 offered each day. Take it from there.
1/ To find out how many tap dance classes are taught each day at the school, we can divide the total number of tap dance classes (28) by the number of days in a week (7).
28 ÷ 7 = 4
Therefore, there are 4 tap dance classes taught each day at the school.
2/ To find out how many ballroom dance classes Brenda can choose from on Tuesday, we can divide the total number of ballroom dance classes (63) by the number of days in a week (7).
63 ÷ 7 = 9
Therefore, Brenda can choose from 9 ballroom dance classes on Tuesday.
3/ To find out how many dance styles have an even number of classes each day, we need to look at the table and identify which dance styles have a number of classes that is divisible by 2.
The dance styles with an even number of classes each day are:
- Ballet: 70
- Salsa: 56
- Ballroom: 63
- Tap: 28
- Swing: 49
So, 5 dance styles have an even number of classes each day.
4/ Amanda says that Step-Up Dance School offers exactly 21 Spanish dance classes each day. To verify if she is correct, we need to check if Flamenco, Salsa, and Tango together add up to 21.
Flamenco: 21
Salsa: 56
Tango: 42
21 + 56 + 42 = 119
Therefore, Amanda is not correct. The total number of Spanish dance classes is 119, not 21.
5/ The information provided is unclear. It states that Cara took all the classes offered in two different styles on Friday, while Oscar took all the swing classes offered that day. However, it does not specify which other style Cara took classes in. As a result, it's impossible to determine which classes Cara took.
6/ To find out how many classes Emily took last week, we need to add up the total number of modern classes she took on Monday and half of the tango classes she took on Wednesday.
Modern: 35
Tango: 42
35 (Monday) + 42 ÷ 2 (Wednesday) = 56
Therefore, Emily took a total of 56 classes last week.
