Figure ACBD is a rectangle. AD = 3 and DC 4. What is the length AC?

Answer»

Given : ACBD is a rectangle. AD = 3 and DC 4.

To Find : length AC

Solution:

ACBD is a rectangle.

A rectangle has all 4 angles right angles

=> ΔADC is right angled at D

Pythagoras' THEOREM: square on the hypotenuse of a right-angled triangle is equal to the sum of the squares of the other two perpendicular sides.

=> AC² = AD² + DC²

=> AC² = 3² + 4²

=> AC² = 9 + 16

=> AC² = 25

=> AC² = 5²

=> AC = 5

Step-by-step EXPLANATION:

LET speed of fast train = x km/hr

speed of slow train = x-10 km/hr

t= 600/x , 600/x-10

600/(x-10) - 600/x =3

19.

.The angles of a triangle are (3x – 30), (4x – 60)° and 2x°. The measures of anglesare

Answer»

PROPERTY USED

ANGLE SUM PROPERTY OF TRIANGLE

SOLUTION

(3x – 30) + (4X – 60) + 2x = 180 ( as discussed above)

3x -30 + 4x -60 + 2x = 180

9x - 90 = 180

9x = 270

x = 270/9 = 30

angles are :

(3x-30) = (3*30 - 30) = 60°

(4x-60) = (4*30 - 30) = 60°

2x = 2*30 = 60°

hence the answer is 60°,60° and 60°

Answer» Given: TOTAL number of apples = 250 Price paid for 250 apples = $22,500 Apples sold = 50 Price at which 50 apples were sold = $120 Remaining 5 apples sold = $1000 To find: Profit or loss and the profit/loss %. Solution: Since 50 apples were sold for 1200, thus price - 50 x 120 = 6000 Next, 200 apples were sold at $1000 per 5 apples, Thus, 200/5 x 1000 = 200000/5 = 40,000 Total sale price - 40,000 + 6000 = $46,000 Total profit = 46000 - 22500 = $23,500 Now, profit % - = Profit x 100 / Cost Price = 23500/22500 x 100 = 104% ANSWER: Mrs. Jones made a profit of $23,500 and the profit % is 104%.

Mrs. Jones bought 250 apples for $22,500. She sold 50 for $120 each, and the remainder she sold 5 for $1000 a parcel.(a) State whether she made a profit or loss.(b) Calculate her percentage profit or percentage loss.

Answer»

Given:

TOTAL number of apples = 250

Price paid for 250 apples = $22,500

Apples sold = 50

Price at which 50 apples were sold = $120

Remaining 5 apples sold = $1000

To find:

Profit or loss and the profit/loss %.

Solution:

Since 50 apples were sold for 1200, thus price -

50 x 120

= 6000

Next, 200 apples were sold at $1000 per 5 apples,

Thus,

200/5 x 1000

= 200000/5

= 40,000

Total sale price -

40,000 + 6000

= $46,000

Total profit = 46000 - 22500

= $23,500

Now, profit % -

= Profit x 100 / Cost Price

= 23500/22500 x 100

= 104%

ANSWER: Mrs. Jones made a profit of $23,500 and the profit % is 104%.

37.	How do I find the focal length?
Answer» Answer: Focal Length = 15cm ImageDistance(v)When The Object Is Placed 20cm Towards The lens = 30cm infront of the lens. Step-by-step explanation: m = -1(Forms Real Image,Convex Lens). m=v/u Therefore,v = -u. Given, -u+v = 60CM (-u because of convex lens) -u-u=60 u=-30cm By lens formula, 1/f=1/v-1/u 1/f=1/30+1/30 1/f=2/30 f=30/2 = 15cm. If The object is moved towards the lens by 20cm u = (-30+20) = -10cm. By lens formula, 1/f=1/v-1/u 1/v=1/15-1/10 1/v=-1/30 v=-30cm Here, Image Distance is Negative Because The Object Is placed Between The Focus And The Lens.Eventhough, In SIGN convention for convex lens the image dstance will be positive. There is a special case of convex lens which can produce VIRTUAL,ERECT and magnified image when the object is placed between focus and the lens. Thank You For Reading My Answer!

How do I find the focal length?

Answer»

Answer:

Focal Length = 15cm

ImageDistance(v)When The Object Is Placed 20cm Towards The lens = 30cm infront of the lens.

Step-by-step explanation:

m = -1(Forms Real Image,Convex Lens).

m=v/u

Therefore,v = -u.

Given,

-u+v = 60CM (-u because of convex lens)

-u-u=60

u=-30cm

By lens formula,

1/f=1/v-1/u

1/f=1/30+1/30

1/f=2/30

f=30/2 = 15cm.

If The object is moved towards the lens by 20cm

u = (-30+20) = -10cm.

By lens formula,

1/f=1/v-1/u

1/v=1/15-1/10

1/v=-1/30

v=-30cm

Here, Image Distance is Negative Because The Object Is placed Between The Focus And The Lens.Eventhough, In SIGN convention for convex lens the image dstance will be positive.

There is a special case of convex lens which can produce VIRTUAL,ERECT and magnified image when the object is placed between focus and the lens.
