How many minutes is 3 hours 45 minutes

How many minutes is 3 hours 45 minutes

3 × 180 + 45 = 540 + 45 = 595 points

How many days is nine hours
9 hours is equal to a few parts of a few days. Make sure that the number of 1 / 5 in 2 is ()

9/24=3/8,2÷（1/5）=10

How many minutes and seconds is 1 / 9 hour?

One hour equals 3600 seconds, 1 / 9 * 3600 = 400 seconds, 400 / 60 = 6 minutes and 40 seconds

I want to know the length and width of the mainstream 13 inch, 14 inch and 15 inch notebooks in the market. Please use the centimeter (CM) unit. Please be clear and careful. I want these data to be useful. Thank you first. If the answer is good, I will give you additional points~

12 inch 3.15cm (H) × 28.50cm (W) × 23.50cm (d)
12.1 inches, length = 10.3 inches = 26 centimeters, width = 6.4 inches = 16.3 centimeters
13.3 inches, 31.5cm, 22.6cm
14 inches, 28.57cm × 21.43cm

Is 15 decimeters equal to 1,5 meters or 0,15 meters

How to solve x-4.5 = 52-x + 6.2
x-4.5=52-x+6.2
52-(-4.5)+6.2
2x=52+6.2+4.5
x=62.7/2
x=31.35
It won't work,

x-4.5=52-x+6.2
x-(-x)=52-(-4.5)+6.2
2x=52+6.2+4.5
x=62.7/2
x=31.35

How to solve 10x 4 (6-x) = 52

Original formula: 40 (6-x) = 52
6-x=13/10
x=47/10=4.7

V = 5cm, find s

V=3/4 πr³
S=4πr²
So s = [& sup3; √ (5 × 4 / 3 π)] & sup2; × 4 π ≈ 20.7

When a = 2.8cm, B = 1.5cm, s = () cm2

S=A*B
S=2.8*1.5=4.2

One side of the parallelogram is 2.5cm, and the other side is 2cm. Calculate the area of the parallelogram

You have to tell us the angle between the two sides
Or the height
Otherwise, it is changeable. As you know, parallelogram is deformed, and its area changes with the angle and height
