B) The marked price of a calculator is Rs 1,800. The shopkeeper allows 10 %
Marina86 [1]

Answer:

m.p=rs1800

discount=10%

discount amount=discount%of mp=10/100×1800=rs180

profit=8%

sp=mp-discount=1800-180=1620

cp=sp-profit%ofcp

cp+profit%ofcp=sp

cp+8/100×cp=1620

cp(1+8/100)=1620

cp=1620/1.08=1500

Find the area of circle b in terms of pi
kondor19780726 [428]
To find the area of the circle use the A = πr²

r (or radius) = 1.5

Plug in 1.5 for r

A = π(1.5)²

Square 1.5

A = π(2.25)

A = 2.25π yd² is your answer

Find the exact value of sin –255°.
alekssr [168]

Answer:

sin(-255°) = √2 + √6/4

Step-by-step explanation:

We need to find sin -255°

We know that sin(-a) = - sin(a)

so, sin(-255°) = - sin 255°

We know that 180° + 75° = 255°

Now we can write sin(255°) = sin(180° + 75°)

We can use the identity:

sin(x+y) = sin(x) cos(y)+cos(x)sin(y)

x = 180° , y = 75°

Solving,

sin(x+y) = sin(x) cos(y)+cos(x)sin(y)

sin(180° + 75°) = sin(180°) cos(75°)+cos(180°)sin( 75°)

sin(180°)  = 0

cos(75°) = √6 -√2/4

cos(180°) = -1

sin( 75°) = √2 + √6/4

Putting values,

sin(180° + 75°) = 0 (√6 -√2/4) + (-1)(√2 + √6/4)

sin(180° + 75°) = -(√2 + √6/4)

We know that sin(-255°) = -sin(255°)

Putting value of sin(255°)

sin(-255°)  = -(-(√2 + √6/4))

sin(-255°) = √2 + √6/4

A parabola y=x^2 is what type of function?
nirvana33 [79]

Step-by-step explanation:

The parabola has a line of symmetry at x=0 so that means we can reflect the function across the y axis and it will remain unchanged so the answer is even function.
