1/8 is the fraction equivalent to the problem above
Answer:
7,273 Pesos
Step-by-step explanation:
1 Peso = $0.055
The formula below converts pesos to dollars:
1 Peso x 0.055 = $1
The formula below converts dollars to pesos:
$1/0.055= 1 Pesos
We use the second formula because we are coverting
<em>from dollars to pesos.</em>
$400/0.055=7,273 Pesos
3x - 2y = 13
-2y = -3x + 13
y = 3/2x - 13/2...slope is 3/2, y int is -13/2
2x + 3y = -16
3y = -2x - 16
y = -2/3x - 16/3...slope = -2/3, y int is -16/3
perpendicular lines will have negative reciprocal slopes. To find the negative reciprocal of a number, flip the number and change the sign.
On the 1st equation, the slope was 3/2....find its negative reciprocal.....flip it, making it 2/3....change the sign...making it -2/3. So the negative reciprocal of 3/2 is -2/3.
So if one equation has a slope of 3/2 and another equation has a slope of -2/3, then these lines are perpendicular <==
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:
1) 4 days 2) P30 3) P125 4) 6 adult 5) smallest number : 57.77 largest number = 72.22
Step-by-step explanation:
1)
6 litres --> 3 days
1 litres --> 1/2 days
8 litres --> 1/2 * 8 = 4 days
2)
3 ball pens --> P18
1 ball pens --> P6
5 ball pens --> P30
3)
12 pencils --> P60
1 pencils --> P5
25 pencils --> P125
4)
7 children --> 2 adults
1 chldren --> 2/7 adults
21 children --> 2/7 * 21 = 6 adult
5) 4:5
4x+5x=130
x = 130/9
4x = 57.77
5x = 72.222
