The LCM is the smallest common multiple of two or more numbers. For example, the LCM of 2 and 5 is 10. The least common factor is the smallest common factor of two or more numbers. The smallest factor of every number is 1.
Answer:
children's: 111 and adults: 62
Explanation:
- given total number of people 173
- total amount received is $306
- during the process, we shall consider x as children and y as adult
make equations:
x + y → 173 [ this was from total people ]
1.5x + 2.25y → $306 [ this was from cost ]
try to make x the subject:
x + y → 173
x → 173 - y ______equation 1
1.5x + 2.25y → $306
1.5x → 306 - 2.25y
x → 
__________equation 2
solve them simultaneously:
= 173 - y
306 - 2.25y = 259.5 - 1.5y
-2.25 + 1.5y = 259.5 - 306
-0.75y = -46.5
y = 62
so there were total 62 adults that day in the public swimming pool.
find children's using:
x → 173 - y
x → 173 - 62
x → 111
so there were total 111 children's that day in the public swimming pool.
Answer:
19 square units
Step-by-step explanation:
There are a LOT of different ways to solve this problem, most of which involve breaking up the shape into smaller shapes. For me, it’s easier to draw a rectangle around the figure, find that area, and then subtract the four areas not in the figure.
Rectangle: would be from -3 to 3 (6) and -2 to 4 (6). 6x6=36
The four missing triangles:
AB = 1/2(3)(2)=3
BC = 1/2(2)(4)=4
CD = 1/2(2)(4)=4
DA = 1/2(4)(3)=6
6+4+4+3=17
36-17=19

Step-by-step explanation:
For this question, we need to find the unit rate. 7.5 is 10% of 75 (which we can find by dividing 75 by 10). Then, in order to get 30 from this, we would have to multiply 7.5 x 4. Because we multiplied this by 4, that hints to us that 40% of 75 is 30. With this knowledge, we can find 40% of 300, which when doing the math would be 120. Therefore, because 30/75 students would want to go to Clemson University, that means 120 students out of 300 would want to go to Clemson University. Thus, our answer is 120 students
