(20m)/(5m) = x/(182cm)

cross multiplying gives:
(5m)*x = (3640)(m)(cm)

dividing yields:
x = 728cm

### What are the dimensions on a Kenmore 363.14192992 dishwasher?

Dishwashers that are installed into standard kitchen cabinets have a standard width and depth of 60 cm (Europe) or 24 inches (US), and most dishwashers must be installed into a hole a minimum of 86 cm (Europe) or 34 inches (US) tall. Portable dishwashers exist in 45 and 60 cm (Europe) 18 and 24 inch (US) widths, with casters and attached countertops. Dishwashers may come in standard or tall tub designs; standard tub dishwashers have a service kickplate beneath the dishwasher door that allows for simpler maintenance and installation, but tall tub dishwashers have approximately 20% more capacity and better sound dampening from having a continuous front door.

### A right angle triangle with length of AB 10cm and AC 20cm, how do I find the angle of BC

Assuming that the angle at A is the right angle, Pythagoras' theorem says that the length of the hypotenuse (the side opposite the right angle) is the square root of the sum of the squares of the other two sides. In your case, AB and AC are 'the other two sides' and BC is the hypotenuse, so:

/ 2 2 /
length BC = V 10 + 20 = V 100 + 400

= V 500 = 22.36 cm

(To find the angle at C, you need trigonometry and is arc-tan(10/20)

and the angle at B is arc-tan(20/10) - 26.5 deg and 63.5 deg)

### I have just purchased an Onkyo TX-SR607 but it is too tall with feet on to fit into my cabinet. I see there are cork pads on each foot - is there a screw under the pad which can be unscrewed to enable me...

Probably, but it will need a fair amount of free airspace around it for ventilation. If a few mm's is the go/no-go difference there won't be enough cooling clearance.

Page 2 of the manual...

"If you install the apparatus in a built-in installation, such as a bookcase or rack, ensure that there is adequate ventilation.

Leave 20 cm (8") of free space at the top and sides and 10 cm (4") at the rear. The rear edge of the shelf or board above the apparatus shall be set 10 cm (4") away from the rear panel or wall, creating a flue-like gap for warm air to escape."

### 20 cm long how many of these blocks placed end to end will cover the length of a wall half a kilometre long/

We know that 1 kilometer is 100000 cm. We only want half a kilometer so divide 100000 by 2 (100000/2) this gives us 50000 cm. The blocks are 20 cm long so we divide 50000 by 20 which is 2500. This is how many block of 20 cm placed end to end will cover half a kilometer.

### Can you gave me a example of a right triangle problems?

In right triangle we are making 90 degree angle triangle, we can have problem for finding hypotenuse or finding sin or cos values of the side of the triangle. For ex,Find out the hypotenuse,sin and cos value of the right triangle with base 4 cm and perpendicular 3 cm Solution:Hypotenuse = SQRT(4^2 + 3^2) =SQRT(4*4 + 3*3) =SQRT(16+9)=SQRT(25)=5 cm For right triangle, sin(x)=3/5=0.6 cos(x)=4/5 =0.8
