A shopkeeper bought 50 kg of sugar he sold 1/4 of the sugar. find the weight of the sugar that was left.

Answer»

Step-by-step explanation:

TOTAL sugar bought by shopkeeper is = 50kg;

1/4 of the 50kg sugar was SOLD = 1/4*(50) = 12.5 KG of sugar was sold out;

Total weight of sugar was LEFT = 50-12.5 = 37.5 kg

Find the acute angle theta such that 2 cos squared theta is equal to 3 sin theta

Answer»

Answer:

30 deg

Step-by-step explanation:

2 \cos ^{2} ( \<klux>ALPHA</klux> )  = 3 \sin( \alpha )  \\ 2 (<klux>1</klux> - \sin ^{2} ( \alpha ))  = 3 \sin( \alpha )

2 \sin^{2} ( \alpha )  + 3 \sin( \alpha )  - 2 = 0 \\ 2 \sin^{2} ( \alpha )  + 4 \sin( \alpha )  -  \sin( \alpha )  - 2 = 0 \\ 2 \sin( \alpha ) ( \sin( \alpha )  + 2) - 1( \sin( \alpha )  + 2) = 0

(2 \sin( \alpha )  - 1)( \sin( \alpha )  + 2) = 0

sin alpha LIES between -1 & 1

\sin( \alpha )  =  \frac{1}{2}

\alpha  = 30deg

The area of a triangular park is 240m. If two sides are 78,and 50m, find the length of the perpendicular on the side of length 50 m from the opposite vertex.Please answer

Answer»

Answer:

PERIMETER of triangular PARK = 240m

LENGTH of two SIDE are- 1) 78m

                                2) 50m

let 3rd side be          = X meter

78+50+x = perimeter of triangle

78+50+x = 240m

128+x     = 240m

x             = 240-128

x             = 112m

therefore, the length of third side is 112m .

Two friends start at the same time from cities P and Q towards cities to Q and P respectively. After meeting at some point between P and Q,they reach their destination in 54 and 24 minutes respectively. In what time did the one who moved from Q to P complete his journey?need explained ans​

Answer»

ANSWER:

N will take 60 mins to complete the entire journey from Q to P.

Step-by-step explanation:

Let the two friends be “M” who will be TRAVELLING from P to Q and “N” who will be travelling from Q to P.

Let us CONSIDER the speed of M be “x” and the speed of N be “y”. Also, let them meet after “t” minutes.

Case 1: Before M & N meets each other

Distance travelled by M = x * t

Distance travelled by N = y * t

Case 2: After M & N crosses each other

Distance travelled by M = x * 54

Distance travelled by N = y * 24

Now,  

(Distance travelled by M & N before meeting each other) = (Distance travelled by M & N after CROSSING each other)

∴ x * t = x * 54 ….. (i)

And, y * t = y * 24 …. (ii)

Multiplying equation (i) & (ii), we get

xy * t² = xy * 54 * 24

or, t² = 1296

or, t = 36

Since we are required to find the time taken by N to travel the entire journey from city Q to P, therefore, N WOULD take 36 + 24 = 60 minutes to complete his entire journey.

1. Prove that the sum of three angles of a triangle is 180°​

Answer»

angles of triangle = 180 degrees

so all the SIDES of the triangle will be xcm

=> x+x+x=180

=>3x=180

=>x=180/3

=>x=60 degrees

so now if we will add 60 three times then the sum will be 180 degrees

Find the value of cos(2π/7) + cos(4π/7) + cos(6π/7) ?​

Answer»

Step-by-step explanation:

Hello...

This is a streamlined version of the PROOF I posted earlier. The trig identities used are:

[a] sin (π-X) = sin x ----used in step 9

[b] sin (π+x) = -sin x ----used in step 8

[c] sin (-x) = -sin x ----used in step 6 (TWICE)

[d] sin 2X = 2 sin x cos x ----used in step 4

[e] sin x cos y = (1/2)sin(x+y) + (1/2)sin(x-y) ----used in step 5 (twice)

1. cos(2π/7) + cos(4π/7) + cos(6π/7) =

2. 2sin(2π/7)[(cos(2π/7) + cos(4π/7) + cos(6π/7)] / 2sin(2π/7) =

3. [2sin(2π/7)cos(2π/7) + 2sin(2π/7)cos(4π/7) + 2sin(2π/7)cos(6π/7)] / 2sin(2π/7) =

4. [sin(4π/7) + 2sin(2π/7)cos(4π/7) + 2sin(2π/7)cos(6π/7)] / 2sin(2π/7) =

5. [sin(4π/7) + sin(6π/7) + sin(-2π/7) + sin(8π/7) + sin(-4π/7)] / 2sin(2π/7) =

6. [sin(4π/7) + sin(6π/7) - sin(2π/7) + sin(8π/7) - sin(4π/7)] / 2sin(2π/7) =

7. [sin(6π/7) - sin(2π/7) + sin(8π/7)] / 2sin(2π/7) =

8. [sin(6π/7) - sin(2π/7) - sin(π/7)] / 2sin(2π/7) =

9. [sin(π/7) - sin(2π/7) - sin(π/7)] / 2sin(2π/7) =

Ramesh sold an article at a certain profit. Had he purchased the article for 12% less and sold it for 24% more, his profit percentage would have been 2.5 times his actual profit percentage. Find his actual profit percentage.

Answer»

Dear Student,

◆ Answer -

Profit % = 28.57 %

● Explanation -

Suppose RAMESH SOLD an article of cost price P at a profit of x %.

If he had purchased it for 12 % LESS and sold it to 24 % more, profit % would have been 2.5 % more.

SP × 124/100 - CP × 88/100 = 2.5 (SP-CP)

1.24SP - 0.88CP = 2.5SP - 2.5CP

2.5CP - 0.88CP = 2.5SP - 1.24CP

1.62CP = 1.26SP

SP = 1.62CP/1.26

SP = 1.2857CP

Profit percentage is calculated as -

Profit % = (SP/CP - 1) × 100

Profit % = (1.2857CP/CP - 1) × 100

Profit % = (1.2857 - 1) 100

Profit % = 28.57 %

Hope that's all...

The area of a triangle ABC is 8cm square in which AB=AC =4cm And angle A is 90 degree

Answer»

AREA of triangle ABC = 1/2 ×BASE × HEIGHT

= 1/2 × AB × AC

= 1/2 × 4× 4

= 2 × 4

= 8 cm square

LET AD IS PERPENDICULAR TO BC

In Triangle ADB AND ADC

AD = AD ( common)

angle ADC = angle ADB ( each 90 degree)

AB = AC (Given)

Triangle ADB (congruent to). triangle ADC ( RHS criteria)

BD = CD ( cpct )

in triangle ABC , BY Pythagoras THEOREM

ABsquare + ACsquare = BC square

4 square +4 square = BCsquare

16 +16 = BCsquare

32 = BC square

:. BC = 4√2 cm

BD + CD = BC

2BD = BC (. BD = CD )

2BD = 4√2

BD = 2√2 cm

now in triangle BAD , by Pythagoras theorem

ADsquare + BD square = ABsquare

ADsquare + 2√2 square = 4 square

ADsquare + 4×2 = 16

ADsquare + 8 = 16

ADsquare = 16- 8

ADsquare = 8

.: AD = √8

.: AD = 2√2 cm

Hence length of perpendicular from A to BC = length of AD = 2√2 cm

The weight of two boxes is 5 3/4 kg . If the weight of one box is 2 5/6 kg. Find the weight of second box?

Answer»

Answer:

2 11/12 Kg.

Step-by-step explanation:

WEIGHT of BOXES = 5 3/4 Kg = 23/4 kg.

Weight of 1 box = 2 5/6 Kg = 17/6 kg.

Weight of 2nd box  =  23/4 - 17/6

                             

                                 =    69 - 34

                                      ------------- = 35/12 = 2 11/12 Kg.

Can you tell where we use milligramme

Answer»

HeyA

To measure weights SMALLER than 1 gram, we can USE MILLIGRAMS (mg) and micrograms (µg). 1000 mg = 1 g, 1000 µg = 1 mg, 1 000 000 µg = 1 g.

These are USED in SCIENCE and medicine and you may find that pills and tablets for vitamins or medicines have values of contents in mg or µg.

Write note on eclipse that you have seen​

Answer»

Answer:

An eclipse is an astronomical event that occurs when an astronomical object is temporarily obscured, EITHER by PASSING into the shadow of ANOTHER body or by having another body pass between it and the viewer. This alignment of three celestial objects is known as a syzygy.[1] Apart from syzygy, the TERM eclipse is ALSO used when a spacecraft reaches a position where it can observe two celestial bodies so aligned. An eclipse is the result of either an occultation (completely hidden) or a transit (partially hidden).
