Answer» Step-by-step EXPLANATION: (-7/5)×[(3/8)+(-7/2) = [(-7/5)×(3/8)]+[(-7/15)×(-7/12)] (-7/5)×(-25/8) = (-21/35) + (49/180) (35/8) = (-2065/6300) (35/8) = 413/1260

2.

verify the distributive property a×(b+c)=(a×b)+(a×c) for the given set of rational numbers -7/15,3/8,-7/12

Answer»

Step-by-step EXPLANATION:

(-7/5)×[(3/8)+(-7/2) = [(-7/5)×(3/8)]+[(-7/15)×(-7/12)]

(-7/5)×(-25/8) = (-21/35) + (49/180)

(35/8) = (-2065/6300)

(35/8) = 413/1260

9.	Paint needs to be thinned to a ratio of 2 parts paint to 1.5 parts water. The painter has by mistake added water so that he has 6 litres of paint which is half water and half paint. What must he add to make the proportions of the mixture correct?A) 1 litre paint B) 1 litre water C) ½ litre water and one litre paint D) ½ litre paint and one litre water
Answer» 1 litre paint Step-by-step explanation: 6 litres of paint which is half water and half paint. 6 litre of paint in ratio 1 : 1 i.e 3 litre paint and 3 litre water Paint needs to be THINNED to a ratio of 2 parts paint to 1.5 parts water. needed ratio = 2 : 1.5 = 4 : 3 If we add X litre to Paint $\frac{3 + x}{3} = \frac{4}{3}$ x = 1 litre. If we add X litre water $\frac{3}{3 + x} = \frac{4}{3}$ X = 3/4 litres we can get multiple results, so it is better to GO with CHOICE based answer. let X, Y be quantity of paint and water respectively. $\frac{3 + x}{3 + y} = \frac{4}{3}$ a) (3+1) / (3+0) = 4/3 b) 3 / (3+1) = 3/4 c) (3+1) / (3+1/2)= 8/7 d) (3+1/2) / (3+1) = 7/8 Hence OPTION A is CORRECT

Paint needs to be thinned to a ratio of 2 parts paint to 1.5 parts water. The painter has by mistake added water so that he has 6 litres of paint which is half water and half paint. What must he add to make the proportions of the mixture correct?A) 1 litre paint B) 1 litre water C) ½ litre water and one litre paint D) ½ litre paint and one litre water

Answer»

1 litre paint

Step-by-step explanation:

6 litres of paint which is half water and half paint.

6 litre of paint in ratio 1 : 1

i.e 3 litre paint and 3 litre water

Paint needs to be THINNED to a ratio of 2 parts paint to 1.5 parts water.

needed ratio = 2 : 1.5 = 4 : 3

If we add X litre to Paint

$\frac{3 + x}{3} = \frac{4}{3}$

x = 1 litre.

If we add X litre water

$\frac{3}{3 + x} = \frac{4}{3}$

X = 3/4 litres

we can get multiple results, so it is better to GO with CHOICE based answer.

let X, Y be quantity of paint and water respectively.

$\frac{3 + x}{3 + y} = \frac{4}{3}$

a) (3+1) / (3+0) = 4/3

b) 3 / (3+1) = 3/4

c) (3+1) / (3+1/2)= 8/7

d) (3+1/2) / (3+1) = 7/8

Hence OPTION A is CORRECT

The price of a chair and a table together is 5000 rupees the price of a table is 2000 rupees more than that of the chaira) what is the price of a chair? b) what is the price of a table?

Answer»

Given:

The price of a chair and a table together is Rs. 5000
The price of a table is Rs. 2000 more than that of a chair

To find:

the price of a chair
the price of a table

Solution:

Let the price of a chair be X and that of a table be y.

By the given CONDITIONS,

x + y = 5000 ... ...(1)
y = x + 2000 ... ...(2)

Substituting y = x + 2000 in (1), we get

x + x + 2000 = 5000
or, 2x = 3000
or, x = 1500

Putting x = 1500 in (2), we get

y = 1500 + 2000
or, y = 3500

Sumitra has rs.34 in 50 Paise and25paise coins . If the number of 25 Paise coins is twice the number of 50Paise coins, how many coins of each kind dose she have?

Answer»

ANSWER:

The number of 50 Paise COIN = 34

The number of 25 Paise coin = 68

Step-by-step explanation:

Let,

The number of 50 Paise coin = x

The number of 25 Paise coin = 2X

Total amount = Rs 34

Rs. 1 = 100 Paise

34 × 100

3400 paise

★ Value of coin :

50 Paise coin = x

50x

25 Paise coin = 2x

2x × 25

50x

★ According to the question :

⇒ 50x + 50x = 3400

⇒ 100x = 3400

⇒ x = 3400 / 100

⇒ x = 34

★ Value of 2x :

⇒ 2 (34)

⇒ 2 × 34

⇒ 68

Therefore,

The number of 50 Paise coin = 34

The number of 25 Paise coin = 68

39.	Determine wether the relation is a function
Answer» Answer: Determining whether a relation is a FUNCTION on a graph is relatively easy by USING the vertical LINE TEST. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. HOWEVER, if a vertical line crosses the relation more than once, the relation is not a function.

The angle of a triangle ABC are in the ratio 2:3:4,find the largest angle of the triangle

Answer»

Answer:

the SUM of triangle is 180 degree

LET RATIOS be 2X, 3x and 4X

2x + 3x + 4x = 180

9x = 180

x = 180/9 =20

angles are

2x = 2* 20 = 40

3x = 3*20 = 60

4x = 4*20 = 80

so the largest angle is 80 degree

Answer» Answer: D=152° Step-by-step explanation: Actually, we don't require measurements for such problems. Here ABCD is a PARALLELOGRAM and we know that line AB and CD are parallel where AD is a transversal so the ANGLES A and D is co-interior , Co-interior angles are SUPPLEMENTARY or the sum of their angles is 180° A+D = 180° D=180°-A we know A=28° D=180°-28° angle D =152°

Find the measure of angle D, and the perimeter and area of parallelogram ABCD. Parallelogram A B C D is shown. Side A B is 17 centimeters. Side A D is 20 centimeters. Angle A is 28 degrees. The height is 8 centimeters.

Answer»

Answer:

D=152°

Step-by-step explanation:

Actually, we don't require measurements for such problems.

Here ABCD is a PARALLELOGRAM and we know that line AB and CD are parallel where AD is a transversal so the ANGLES A and D is co-interior , Co-interior angles are SUPPLEMENTARY or the sum of their angles is 180°

A+D = 180°

D=180°-A

we know A=28°

D=180°-28°

angle D =152°

1023. Sarika had 2400. She spent į of her money on food and į of the remainder on stationary items.How much money is left with her?

Answer»

Step-by-step explanation:

Total rupees=400

Money spent on food= 1/2*400=200

Remaining money =200

Money spent on stationary =2/3*200

=400/3

Total money spent=200+(400/3)

=1000/3

Money LEFT =400-(1000/3)

=200/3
