R: steve has three lengths of fence . he connects them to make a triangular pen for his dog .if the lengths are 5 meters , 6 meters , and 10 meters , what tyoe of triangle is formed by the dog pen

Step-by-step explanation:

The angle opposite the 10 meter length is greater than 90. It calculates out to be about 130 degrees. The triangle is obtuse.

As a note that dog is going to be very uncomfortable. He does not have much room to move around. Let's hope he's something like a Chihuahua.  The height of the triangle from the 130 degree angle's apex is about 2 meters.

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
