Answer:

1 ) RS 100

2 ) RS 50

3 ) RS 72

4 ) RS 350

Step-by-step explanation:

1 )

Cost of 1 kg of newspaper = RS 5.

Cost of 20 kg of newspaper

= 20 x 5

= RS 100

2 )

Cost of for 1 kg of iron = RS 10

Cost of for 5 kg of iron

= 5 x 10

= RS 50

3 )

Cost of 1 kg of Plastic = RS 8

Cost of 9 kg of Plastic

= 9 x 8

= RS 72

4 )

Cost of 1 kg of Brass = RS 50

Cost of 7 kg of Brass

= 7 x 50

= RS 350

If each quadrilateral below is a parallelogram,find the missing measures.
zhenek [66]

Answer:

Part 1) MN=31\ units

Part 2) KN=45\ units

Part 3) m∠K=61°

Part 4) m∠L=119°

Part 5) m∠M=61°

Step-by-step explanation:

we know that

In a parallelogram opposite angles and opposite sides are congruent and consecutive angles are supplementary

Part 1) Find the side MN

we know that

MN≅KL ----> by opposite sides

we have

KL=31\ units

therefore

MN=31\ units

Part 2) Find the side KN

we know that

KN≅LM ----> by opposite sides

we have

LM=45\ units

therefore

KN=45\ units

Part 3) Find the measure of angle K

we know that

m∠K+m∠N=180° ----> by consecutive interior angles

we have

m∠N=119°

substitute

m∠K+119°=180°

m∠K=180°-119°

m∠K=61°

Part 4) Find the measure of angle L

we know that

m∠L≅m∠N ----> by opposite angles

we have

m∠N=119°

therefore

m∠L=119°

Part 5) Find the measure of angle M

we know that

m∠M≅m∠K ----> by opposite angles

we have

m∠K=61°

therefore

m∠M=61°

An equiangular triangle has one side of length six inches. What is the height of the triangle, drawn from that side, to the near
Mandarinka [93]

9514 1404 393

Answer:

  5.2 in

Step-by-step explanation:

An equiangular triangle is also equilateral. All sides will be 6 inches, and the height line will be a perpendicular bisector of the side.

Using trig, the height is ...

  (3 in)tan(60°) = 3√3 in ≈ 5.2 in

Using the Pythagorean theorem, ...

  h² = 6² -3² = 27

  h = √27 ≈ 5.2 . . . inches

Question 10
kozerog [31]

The regular selling price per unit for the laptop is $298.6.

<h3>How to calculate the price?</h3>

Let the regular price per unit be x.

The expense is 19% of the selling price and profit is 25% of the selling price. This will be illustrated as:

x + (19% × x) + (25% × x) = 430

x + 0.19x + 0.25x = 440

1.44x = 430

Divide

x = 430 / 1.44

x = 298.6

The price is $298.6
