Step-by-step explanation:

<h3>• C. P = Cost Price.. , S. P (Sell Price) , </h3>

<h3>→ C.P = 100×S.P/100+Profit (when profit) </h3>

<h3>(a) C.P = 100 × 55/100 + 10 = 5500/110 </h3>

<h2> C.P » $ 50</h2><h3 /><h3 /><h3>(b) C.P = 100 × 558/100+24 = 55800/124 </h3>

<h2> C.P » $ 450</h2><h3 /><h3 /><h3 /><h3 /><h3 /><h3>→ C. P = 100 × S.P/100 - loss (when loss) </h3>

<h3> (c) C. P = 100 × 680 / 100 - 15 = 68000/85</h3>

<h2> C. P » $ 800</h2>

<h3>(d) C. P = 100 × 11.78 / 100 - 5 = 1178/95 </h3>

<h2> C. P » $ 12.4</h2>

OM , ON and OP are the angle bisectors of ∠AOB, ∠BOC, and ∠COD respectively. ∠AOD and ∠BOE are straight angles.
Orlov [11]

Find m∠BOC, if m∠MOP = 110°.

Answer:

m∠BOC= 40 degrees

Step-by-step explanation:

A diagram has been drawn and attached below.

  • OM bisects AOB into angles x and x respectively
  • ON bisects ∠BOC into angles y and y respectively
  • OP bisects ∠COD into angles z and z respectively.

Since ∠AOD is a straight line

x+x+y+y+z+z=180 degrees

2x+2y+2z=180^\circ

We are given that:

m∠MOP = 110°.

From the diagram

∠MOP=x+2y+z

Therefore:

x+2y+z=110°.

Solving simultaneously by subtraction

2x+2y+2z=180^\circ

x+2y+z=110°.

We obtain:

x+z=70°

Since we are required to find ∠BOC

∠BOC=2y

Therefore from x+2y+z=110° (since x+z=70°)

70+2y=110

2y=110-70

2y=40

Therefore:

m∠BOC= 40 degrees

If a set of data is in the direction of a downward line, which of the following would be the best model for this data?
Ahat [919]
I'm not too sure about this, but I feel that it's a linear regression. A quadratic one eventually reverses direction, and an exponential one levels off and stops decreasing.
