the volumes of two cones are in the ratio 1 : 10 and the radii of the cones are in the ratio 1 : 2. what is the ratio of length of wire.​

Answer»

Answer:( i THINK that ratio of HEIGHT need to be calculated).

The ratio of the height of the cines will be 2:5

Step-by-step explanation:

Let the two radius be r1 and r2

And height will be h1 and h2

Since the ratio of volume is 1:10

THUS V1/V2=1/10 which will give

r1^2 h1 / r2^2 h2 =1/10 ---(1)

and r1 /r2 = 1/2 ( GIVEN ) thus putting in 1 gives h1/h2 = 2/5

Thus the required ratio of height will be 2/5

The following table shows thlowing table shows the frequency table of literacy rate (in percentage) ofties Find the mean literacy rate by assumed mean method :Heracy rate (in percentage) 45 – 55 55 – 65 65 – 75 75 – 85 85 – 95Number of cities3 10 11 8 3|Take 70 as the assumed mean. Find mean up to two places of decimal.​

Answer»

Answer:

Mean = 69.43

Step-by-step explanation:

We are given below the following table that shows the frequency table of literacy rate (in percentage) of  cities;

  Literacy rate(in %)       Number of cities (f)     X        d = \frac{X-A}{h}        f * d

    45 - 55                                    3                        50           -2               -6            

    55 - 65                                   10                        60           -1               -10

    65 - 75                                    11                        70            0                0

    75 - 85                                    8                         80            1                8

    85 - 95                                    3                         90           2                6        

                                             ∑ f = 35                                             ∑f*d = -2     

Here, X is calculated as (Upper limit + Lower limit) ÷ 2 .

Assumed Mean method formula is given by;

        Mean = A+\frac{\sum fd}{\sum f} * h   where, A = assumed mean = 70

                                                         h = width of class INTERVAL = 10

        Mean = 70+\frac{-2}{35} * 10

                   = 70 - \frac{4}{7} = 69.43

Therefore, mean literacy rate by assumed mean method is 69.43 .

Construct an isosceles triangle if one of its altitudes is 5 cm.

Answer»

Constructed ΔABC as isosceles TRIANGLE with CD altitude = 5 cm

Step-by-step explanation:

Step 1 : Draw a line segment AB  of any length

Step 2 : Using Compass Width slightly less than AB , & takig A as center Draw ARCS on both sides of AB

Step 3 : Using Same Compass as in step 2  , & taking B as center Draw arcs on both sides of AB such that it intersect arc drawn in step 2 at P & Q

Step 4 : Draw a line passing through PQ & intersecting AB at D

Step 5 : Taking Compass width = 5 cm & D sa center , intersect line drawn in step 4 at  C

Step 6 : join AC  & BC

AC = BC  & CD = 5 cm

33. A circular plot of land is ofradius 49 m. A path 3.5 mwide needs to be paved aroundthis plot. Find the cost ofpaving this path at the rateof 30 per sq. m.​

Answer»

ANSWER:

First the total circle area of RADIUS 49 m is

= 22/7 × 49 × 495

= 7546 sq.m

Next, the circle without the path with radius 49 - 3.5 = 45.5

= 22/7 × 45.5 × 45.5

= 6506.5 sq.m

Area of path = Big circle area - small circle area

= 7546 - 6506.5

= 1039.5 sq.m

Cost of paving the path = 1039.5 × 30

= RS. 31,185

Therefore, Rs 31185 is needed to pave the path

Answer»

GIVEN :  एक ठोस घन को पीला, नीला और काला इस प्रकार  रँगा गया है कि इसके विपरीत फलक एक ही रंग के हैं ।  तब इस घनं को दो भिन्न आमापों के 36 घनों में इस  प्रकार काटा गया है कि 32 घन छोटे हैं और अन्य 4 घन | बड़े घनों का कोई भी फलक नीला नहीं रँगा|

To Find : कितने घनों में केवल एक फलक रंगा हुआ

Solution:

32 घन छोटे हैं   1 * 1 * 1   = 32

4 घन बड़े हैं    2 * 2 * 2   = 32

ठोस घन = 4 * 4 * 4 = 64  ( 32 + 32)

बड़े घनों का कोई भी फलक नीला नहीं रँगा|

बड़े घन - पीला,  काला

केवल एक फलक रंगा हुआ =  2 * (4 - 2)(4 - 2)

= 8  

फलक नीला  

8 घनों में केवल एक फलक रंगा हुआ

The base angles of an isosceles triarigleare each 24º more than the top angle. Find the measures of all the Angles of an isosceles triangle ​

Answer»

*Answer*

1ST base angle = 24 + x

2nd base angle = 24 + x

3rd top angle = x

Now , by angle sum property ,

24 + x + 24 + x + x = 180

48 + 3X = 180

3x = 180 - 48

x = 132/3

x = 44

Now 24 + x = 68

So each base angle is 68

and top angle is 24

*Check*

68 + 68 + 24 = 180...

If the temperature is 86 degree fahrenheit what is the temperature in Celsius​

Answer»

Answer:

86° F = 30° C

Step-by-step explanation:

TEMPERATURE = 86° F

To convert into CELCIUS,

°C=(°F -32°)x 5/9

°C=(86°-32°)x 5/9

°C=54°x 5/9

°C=270°/9

°C=30°
