Answer:
There are 250 students.
Step-by-step explanation:
I reasoned....
If 24% purchased their lunch, then 76% brought their lunch -- because 100% (the total) - 24% = 76%.
So, I set up this up to find the missing number:
190 x
------ = ------
76% 24%
190 x 24 = 4,560
4,560 / 76 = 60
So, x = 60 students, which represents the 24% of students who purchased their lunch.
190 + 60 = 250
Answer:
D) Rotation of 180 degrees about its center.
Step-by-step explanation:
because when you turn that shape in 180 degres is going to be in the same coordinates.
Ok so 7 times 4 is 28 so she read 28 the first day. For the second day since 40-28= 12, 12 divided by 2 is 6. So she read 6 pages per hour.
Answer:
sin θ + cos θ
Step-by-step explanation:
(sin²θ + cos²θ) (sin θ + cos θ)
(1) (sin θ + cos θ)
sin θ + cos θ
Answer:
Question #3: Answer = 31
Step-by-step explanation
• Plug in 3 for x
• Plug in -4 for y
| -3(3)² + 2(-4) | -(3)(-4)
From here, simplify. Don't forget to use PEMDAS!
| -27 +8 | + 12
| -19 | + 12
19 + 12
31
Use this same method to solve for Question #2!
