Hi there!
If any term, no matter what the number multiplied by zero will always turn out to be zero. I can give you an example of why this is correct.
We'll use apples. :P
If we have four apples multiplied by zero, you'd have zero apple because there's NO groups of apples to use.
Two times three is six because there are two groups of three, or three groups of two. But since earlier we said that there were zero groups of apples, there is zero groups of four so that cancels out to make none.
Hope this helps! :D
Answer:
A school wanted to see how many students bought orange juice with their lunch. As a result, they sampled 100 lunch-buying students, to see how many of them bought orange juice. In a sample of 100 lunch-buying students, 25 of them bought orange juice with their lunches. If there are 1,000 students in the school that buy lunch, how many students bought orange juice with their food? 250.
Step-by-step explanation:
I'm assuming there's no visual included in the question, and that the example can be completely original.
If you wanted a ratio, you would ask what the ratio was between students that bought lunch and students that bought orange juice with their lunches (often asked in lowest terms).
- Sample included 100:25
- You want it in lowest terms. Find the lowest common denominator
- LCD = 5
- New ratio, divided by five to find lowest terms
- = 20:5
- Every 20 students, 5 of them (also 25% of them) bought orange juice with their lunches.
Answer:
the given equation is y=4/7x
reciprocating both sides you get y/x =7/4
now x and y are directly porportional to each other so
x=ky where k is the constant
or x/y=k ......................(2)
equating 1 and 2
k=7/4

Answer:
-2
Step-by-step explanation:
Subtract 10 on both sides:
6x +10= -2
-10 -10
6x = -12
Divide by 6 on both sides:
6x = -12
/6 /6
x = -2
Answer:
yes
Step-by-step explanation:
Her name is 6 letters long, so she will need 6×3.4 cm = 20.4 cm. That is the length she has, so she will make enough spaces.
