. A trader bought A TV set for Birr 2000 and sold it at loss of 11/2% what:was the selling price?

olga nikolaevna [1]

Answer:

1890

Step-by-step explanation:

Loss = 11/2 % = 5.5 %

Cost price = 2000

Loss = 5.5% of cost price

= 5.5% * 2000

$= \frac{5.5}{100}*2000\\\\= 5.5*20\\= 110$

Selling price = Cost price - loss

= 2000 - 110

= 1890

In the diagram below <br> Please help I’ll give brainliest

Luda [366]

Answer:

m<GFA = 110

Step-by-step explanation:

1. ABCD - parallelogram Definition of a parallelogram

(AB ll CD) (AD ll BC)

2. m<B + m<C = 180 Consectuive angles in a

110 + m<C = 180 parallelogram are supplementary

m<C = 70

3. m<GCB = 1/2 m<C Definition of angles bisector

m<GCB = 70

4. m<B = m<D = 110 Opposite angles in a

parrallelogram are congruent

5. m<CDG = 1/2 m<D Defintion of an angle bisector

m<CDG = 55

6. m<GCB+m<CDG+m<CGD=180 Sum of anlges in a triangle (ΔCDG)

70 + 55 + m<CGD = 180

125 + m<CGD = 180

m<CGD = 55

7. m<CGD + m<DGF = 180 Linear pair, supplmentary angles

55 + m<DGF = 180

m<DGF = 125

8. m<C = m<A = 70 Opposite angles in a paralellogram

are congruent

9. m<ADG = 1/2m<D Definiton of an angle bisector

m<ADG = 55

10.m<ADG+m<DFG+m<GFA+m<A=360 Sum of angles in quadrilateral

55 + 125 + m<GFA + 70 = 360 DGFA

m<GFA + 250 = 360

m<GFA = 110

A 2000 gallon fish aquarium can be filled by water flowing at a constant rate in 10 hours. When a decorativve rock is placed in

Elza [17]

Answer:

The volume of the rock is 13.368 cubic feet.

Step-by-step explanation:

The volume of the rock ( $V_{r}$ ), measured in gallons, is equal to the volume of the fish aquarium without the decorative rock ( $V'$ ) minus the volume of the fish aquarium with the decorative rock ( $V''$ ), both measured in gallons.

Since the water flow is at constant rate, the volume of the rock is expressed by the following equation:

$V_{r} = V' - V''$

$V_{r} = \dot V \cdot (\Delta t_{1}-\Delta t_{2})$ (1)

Where:

$\dot V$ - Flow rate, measured in gallons per hour.

$\Delta t_{1}$ - Filling time of the fish aquarium without the decorative rock, measured in hours.

$\Delta t_{2}$ - Filling time of the fish aquarium with the decorative rock, measured in hours.

And the flow rate is:

$\dot V = \frac{2000\,gal}{10\,h}$

$\dot V = 200\,\frac{gal}{h}$

The flow rate is 200 gallons per hour.

If we know that $\dot V = 200\,\frac{gal}{h}$ , $\Delta t_{1} = 10\,h$ and $\Delta t_{2} = 9.5\,h$ , then the volume of the rock is:

$V_{r} = \left(200\,\frac{gal}{h}\right)\cdot (10\,h-9.5\,h)$

$V_{r} = 100\,gal$

$V_{r} = 13.368\,ft^{3}$

The volume of the rock is 13.368 cubic feet.
