Answer» Let the first cash prize = x so NEXT 7 cash PRIZES would be consecutive that is x+25, x+50, x+75, x+100, x+125, x+150, x+175 Adding all gives x + x+25 + x+50 + x+75 + x+100 + x+125 + x+150 + x+175 = 2700 8x + 700 = 2700 8x = 2000 x = 250 So value of first prize = 250 all consecutive prize will be 250 + 25= 275 250 + 50= 300 250 + 75= 325 250 + 100= 350 250 + 125= 375 250 + 150= 400 250 + 175= 425

5.

A sum of rs 2700 is to be used to give eight cash prizes to student of a school for their overall academic performance. If each prize is rs 25 more than its preciding prize find the value of each of the prizes

Answer»

Let the first cash prize = x

so NEXT 7 cash PRIZES would be consecutive

that is x+25, x+50, x+75, x+100, x+125, x+150, x+175

Adding all gives x + x+25 + x+50 + x+75 + x+100 + x+125 + x+150 + x+175 = 2700

8x + 700 = 2700

8x = 2000

x = 250

So value of first prize = 250

all consecutive prize will be 250 + 25= 275

250 + 50= 300

250 + 75= 325

250 + 100= 350

250 + 125= 375

250 + 150= 400

250 + 175= 425

12.

In the adjacent figure PQ || ST, ∠PQR=110° and ∠RST=130°, find ∠QRS.[Hint : Draw a line parallel to ST through point R.]

Answer»

Interior angles on the same SIDE of the transversal:The pair of interior angles on the same side of the transversal are called consecutive interior angles or allied angles or co interior angles.

If a transversal INTERSECTS two PARALLEL Lines then each pair of interior angles on the same side of the transversal is supplementary.

If a transversal intersects two lines such that a pair of alternate interior angles is EQUAL then the two lines are parallel.

SOLUTION :

GIVEN :PQ || ST, ∠PQR = 110° and ∠RST = 130°

Construction:A line XY parallel to PQ and ST is drawn.

∠PQR + ∠QRX = 180° (Angles on the same side of transversal.)

110° + ∠QRX = 180°

∠QRX = 180° - 110°

∠QRX = 70°

Also,∠RST + ∠SRY = 180° (Angles on the same side of transversal.)

130° + ∠SRY = 180°

∠SRY = 50°

Now,∠QRX +∠SRY + ∠QRS = 180°

70° + 50° + ∠QRS = 180°

∠QRS = 60°

Hence, ∠QRS = 60°

24.	If a=5+2√6 , then find the value of a2+1/a2
Answer» Identities USED : ${(a + b)}^{2} = {a}^{2} + {b}^{2} + 2ab \\ \\ {(a - b)}^{2} = {a}^{2} + {b}^{2} - 2ab \\ \\ (a + b)(a - b) = {a}^{2} - {b}^{2}$ Given, a = 5+ 2√6 So, $\frac{1}{a} = \frac{1}{5 + 2 \sqrt{6} } \\$ On rationalizing the DENOMINATOR we get, $\frac{1}{a} = \frac{1}{5 + 2 \sqrt{6} } \times \frac{5 - 2 \sqrt{6} }{5 - 2 \sqrt{6} } \\ \\ \frac{1}{a} = \frac{5 - 2 \sqrt{6} }{ {(5)}^{2} - {(2 \sqrt{6} )}^{2} } \\ \\ \frac{1}{a} = \frac{5 - 2 \sqrt{6} }{25 - 24} \\ \\ \frac{1}{a} = 5 - 2 \sqrt{6}$ Now, $a + \frac{1}{a} = (5 + 2 \sqrt{6} ) + (5 - 2 \sqrt{6} ) \\ \\ a + \frac{1}{a} = 5 + 2 \sqrt{6} + 5 - 2 \sqrt{6} \\ \\ a + \frac{1}{a} = 10$ Squaring both the SIDES we get, ${(a + \frac{1}{a} )}^{2} = {(10)}^{2} \\ \\ {a}^{2} + {( \frac{1}{a} )}^{2} + 2 \times a \times \frac{1}{a} = 100 \\ \\ {a}^{2} + \frac{1}{ {a}^{2} } = 100 - 2 \\ \\ { a }^{2} + \frac{1}{ {a}^{2} } = 98$

Answer» Hello, Answer: 46,000 trees solution: At starting number of trees are 40,000. Objective is to increase 5% so 5% of 40,000 = (540000)/100 = 20,0000/100 = 2000 In one years 2000 PLANTS to be planted,so in three years = 32000 trees = 6000 trees Expected number of tree after 3 years = 46,000 trees. 2) If 5% is calculated on present trees after 1 year TOTAL trees 42,000. 5% of 42,000= (542000)/100 =2100 after second year trees are 42000+2100 = 44100 trees 5% of 44100 = (544100)/100 = 2205 after 3 year expected trees= 44100+2205 = 46305 trees.

Step-by-step explanation:

From the figure ,

DE //BC ,

AC = 6 cm, DE = 3 cm.

∆ABC ~ ∆ADE

$\frac{AE}{AC}=\frac{DE}{BC}$

/*Since , CORRESPONDING sides are in proportion */

$\implies \frac{AE}{6}=\frac{3}{BC}$

$\implies AE = \frac{6\times 3}{BC}\\=\frac{18}{BC}$
