Answer:
n is 20
Step-by-step explanation:
If n/8=2.5, then you can just do 8*2.5 to find n. 2.5*8=20
Answer:
$81
Step-by-step explanation:
To find this, we have to use various steps.
Each day, she works 4.5 hours and 12 dollars each hour.
So: 4.5x12= 54
She works 5 days a week
So: 54x5=270
She deposits 70 percent So she saves 30%.
So: 270x.3= 81
3,000 + 500 + 40 + 3 + 0.2 + 0.01
I hope this helps.
1 km = 1000 m.....so 4 km = (4 * 1000) = 4000 m...so she runs 4000 meters per day.
each lap is 400 meters.....4000/400 = 10 laps per day
for 3 days.....(3 * 10) = 30 laps in 3 days
Answer:
1.) It's 20th century painting
2.) 0.5 probability
Step-by-step explanation:
If the universal = 60
We need to first get the value of X. That is,
x (x - 2) + x + 2x + 8 + 10 = 60
First open the bracket
x^2 - 2x + x + 2x + 8 + 10 = 60
x^2 + x + 18 = 60
x^2 + x - 42 = 0
Factorise the above equation
x^2 + 7x - 6x - 42 = 0
x (x + 7) -6(x + 7) = 0
x = 6 or - 7
Since x can't be negative, so we will ignore -7
The value for T = 6(6 - 2) = 6×4 = 24
The value for B = 2(6) + 8 = 12 + 8 = 20
If a painting is chosen from random,
If it's from 20th century, the probability will be 34/60 = 0.567
If it's from British painting, the probability will be 30/60 = 0.5
We can therefore conclude that it's from 20th century painting since it has higher value of probability.
The the probability of choosing a British painting will be 30/60 = 0.5
