Answer» Total length of lace = 20m tables dimensions (length and breadth) = 1m, 50 cm = 1m, 0.5 m perimeter for the table (rectangular table) = 2(length + breadth) = 2(1 + 0.5) = 3m so 3m is the required length of lace for 1 table THEREFORE lace required for 5 table will be = 5 × 3 = 15 m Hence RITA used 15m of lace for 5 tables.

Rita brought a roll of 20 m lace. She wants to put it around 5 table cloths. Each table cloth is 1m long and 50 cm wide. How much lace is used?

Answer»

Total length of lace = 20m

tables dimensions (length and breadth)

= 1m, 50 cm = 1m, 0.5 m

perimeter for the table (rectangular table)

= 2(length + breadth)

= 2(1 + 0.5)

= 3m

so 3m is the required length of lace for 1 table

THEREFORE lace required for 5 table will be

= 5 × 3

= 15 m

Hence RITA used 15m of lace for 5 tables.

And 5 meter lace is left.

hope it helps!!!!

15.	Archana got a 30% hike in her salary this year. Her present salary now becomes 95000 per month. Find her salary before the increment.
Answer» Answer: Approximately 73076.9 Step-by-step EXPLANATION: Let Archna's original salary be: x. Her Present Salary: 95,000. INCREASE% in her salary: 30%. New salary: Original salary - (Original Salary × Percentage increase/ 100) HENCE, we get, x + [x (30/100)] = 95000 →x + (3x/10) = 95000 →(10x + 3x)/10 = 95000 →13x/10 = 95000 {TRANSPOSING 13/10 to RHS...} →x = 95000(10/13) →x = 73076.9{Approx.} Hence, ARCHANA's original salary was Approximately 73076.9 {Hope it helped you...} {Kindly Mark as Brainliest...}

Archana got a 30% hike in her salary this year. Her present salary now becomes 95000 per month. Find her salary before the increment.

Answer»

Answer:

Approximately 73076.9

Step-by-step EXPLANATION:

Let Archna's original salary be: x.

Her Present Salary: 95,000.

INCREASE% in her salary: 30%.

New salary: Original salary - (Original Salary × Percentage increase/ 100)

HENCE, we get,

x + [x (30/100)] = 95000

→x + (3x/10) = 95000

→(10x + 3x)/10 = 95000

→13x/10 = 95000

{TRANSPOSING 13/10 to RHS...}

→x = 95000(10/13)

→x = 73076.9{Approx.}

Hence, ARCHANA's original salary was Approximately 73076.9

in a building there are 24 cylindrical pillars.the radius of each pillar is 28cm and cost of painting the pillars at the rate of ₹8 per square metre

Answer»

Radius of cylinderical pillars

height ,h=4m

curved surface AREA of a CYLINDER =2πrh

curved surface area of a pillar= 2×22\6×0.28×4=7.04metresq.

Curved surface area of 24 such pillars = 7.04×24=168.96metresq.

The exterior angles of an octagon are in the ratio of 1;3:4:2:1:2:3: 2. Find all the interior angles of octagon

Answer»

Let 1ST angle = X

2nd angle = 3X

3RD angle = 4x

4th angle = 2x

5th angle = x

6th angle = 2x

7th angle = 3x

8th angle = 2x

SUM of angle in octagon = 360°

$\bf According \: to \: Question :$

$x + 3x + 4x + 2x + x + 2x + 3x + 2x = 360 \\ \\ 18x = 360 \\ \\ x = \frac{360}{18} \\ \\ \large\boxed{ \green {\bf x = 20}}$

1st angle = 20°

Answer» Answer: The wheel has to ROTATE 183636 times Step-by-step explanation: Diameter (including the tyre) = 70 cm Radius (including the tyre) R = (Diameter)/2 = 70/2 = 35 cm Perimeter of the wheel = $2\pi R$ = $2\frac{22}{7} 35$ cm = 220 cm So in one REVOLUTION of the wheel, the MOVES 220 cm. Now, 404 km = 404 * 1000 metre = 404 * 1000 * 100 cm = 40400000 cm The cycle moves 220 cm in 1 revolution of the wheel The cycle moves 1 cm in $\frac{1}{220}$ revolution of the wheel So, the cycle moves 40400000 cm in $\frac{1}{220}*40400000$ revolution of the wheel = 183636 revolution of the wheel.

Diameter (including the tyre) = 70 cm

Radius (including the tyre) R = (Diameter)/2 = 70/2 = 35 cm

Perimeter of the wheel = $2\pi R$ = $2*\frac{22}{7} * 35$ cm = 220 cm

So in one REVOLUTION of the wheel, the MOVES 220 cm.

Now, 404 km = 404 * 1000 metre = 404 * 1000 * 100 cm = 40400000 cm

The cycle moves 220 cm in 1 revolution of the wheel

The cycle moves 1 cm in $\frac{1}{220}$ revolution of the wheel

So, the cycle moves 40400000 cm in $\frac{1}{220}*40400000$ revolution of the wheel = 183636 revolution of the wheel.

31.	The speed of boat in still water is 12km/h. It can goes 36 km upstream and return to downstream to the original point in 8 hours. Find the speed of stream.
Answer» SOLUTION: Given: Speed of boat in still water = 12 km/h Total DISTANCE = 36 km To Find: Speed of stream. Let, the speed of the stream = x km/h So, Speed of boat in downstream = (12 + x) km/h Speed of boat in upstream = (12 - x) km/h Now, ACCORDING to question, $\implies \sf \dfrac{36}{12+x}+\dfrac{36}{12-x}=8\\ \\ \\ \implies \sf \dfrac{432-36x+432+36x}{144-x^{2}}=8\\ \\ \\ \implies \sf \dfrac{864}{144-x^{2}}=8\\ \\ \\ \implies \sf 1152-8x^{2}=864\\ \\ \\ \implies 8x^{2}=1152-864\\ \\ \\ \implies \sf 8x^{2}=288\\ \\ \\ \implies \sf x^{2}=\dfrac{288}{8}\\ \\ \\ \implies x^{2}=36\\ \\ \implies x=\sqrt{36}\\ \\ \implies \sf x = \pm 6$ As we know that distance cannot be negative. So x = 6 Hence, Speed of stream = 6 km/h.

The speed of boat in still water is 12km/h. It can goes 36 km upstream and return to downstream to the original point in 8 hours. Find the speed of stream.

Answer»

SOLUTION:

Given:

Speed of boat in still water = 12 km/h
Total DISTANCE = 36 km

To Find:

Speed of stream.

Let, the speed of the stream = x km/h

So, Speed of boat in downstream = (12 + x) km/h

Speed of boat in upstream = (12 - x) km/h

Now, ACCORDING to question,

$\implies \sf \dfrac{36}{12+x}+\dfrac{36}{12-x}=8\\ \\ \\ \implies \sf \dfrac{432-36x+432+36x}{144-x^{2}}=8\\ \\ \\ \implies \sf \dfrac{864}{144-x^{2}}=8\\ \\ \\ \implies \sf 1152-8x^{2}=864\\ \\ \\ \implies 8x^{2}=1152-864\\ \\ \\ \implies \sf 8x^{2}=288\\ \\ \\ \implies \sf x^{2}=\dfrac{288}{8}\\ \\ \\ \implies x^{2}=36\\ \\ \implies x=\sqrt{36}\\ \\ \implies \sf x = \pm 6$

As we know that distance cannot be negative. So x = 6

Hence, Speed of stream = 6 km/h.

। एक ठोस बेलनाकार है जिसके दोनों सिरे अर्द्धगोलाकारहैं । ठोस की कुल ऊँचाई 20 सेमी है तथा बेलन का- व्यास 7 सेमी है । ठोस का कुल आयतन ज्ञात कीजिए।

Answer»

Answer:

Sorry MATE, I can't write in Hindi, but I'll give the answer in simplest English possible.

Radius of HEMISPHERE = 7/2 cm

Height of object (ठोस बेलनाकार) = 20 cm

VOLUME (आयतन) of CYLINDER = $\tt{\pi r^{2} h}$

= 22/7 × 7/2 × 7/2 × 20

= 770 cu. cm

Volume (आयतन) of 2 hemispheres = $\tt{2 \times \frac{2}{3} \pi r^{3}}\\$

= 4/3 × 22/7 × 7/2 × 7/2 × 7/2

= 179.67 cu. cm

Total volume = 770 + 179.67

= 949.67 cu cm
