It helps you know what to multiply and the product when you subtracting and adding fractions.
Both of them together have 690 because you subtract 152 from 421 so...
421-152=269
Then add 269 to 421
421+269=690
63 dives by 7 is 9 so 63-9 is 54
Answer 54
Answer:
Step-by-step explanation:
1. sin 30 = x/16
x= 16 sin 30
x = 8
2. cos 60 = 22/x
x = 22/cos 60
x = 44
3. tan 45 = x/19
x = 19 tan 45
x= 19
4. tan 16 = x/13
x = 13 tan 16
x= 3.73
5. sin 54 = x/45
x = 45 sin 54
x= 36.41
6. sin 35 = z/23
z = 23 sin 35
z = 13.19
Answer:
The total cost of the party is approximately $2300, hence the correct answer is option D.
Step-by-step explanation:
Given:
Number of students = 295 students
cost per student = $8.95
Discounts given by the company = $400
To find:
We need to estimate the total cost of the party.
Solution:
To find the total cost of the party we need to multiply the total number of students into the cost per student.
This can be done as follows:
=295×8.95
=2640.25
Therefore, the total cost of the party is $2640.25, but it is given that the laser tag company gave the students a discount of $400. Hence the total cost after discount is
=2640.25-400
=2240.25
Therefore, the total cost of the party is approximately $2300
Hence the correct answer is option D.
