y = StartFraction 3 Over 7 EndFractionx – StartFraction 20 Over 7 EndFraction
c.
y = Negative StartFraction 3 Over 7 EndFractionx + StartFraction 7 Over 20 EndFraction
b.
y = Negative StartFraction 3 Over 7 EndFractionx + StartFraction 20 Over 7 EndFraction
d.
y = Negative StartFraction 3 Over 7 EndFractionx – StartFraction 20 Over 7 EndFraction

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

the answer is 21%.

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.
