The sum of three numbers is 98. Of the ratio between

Answer»

Answer:

The sum of three numbers is 98.The RATIO of the first to the second is 2/3,and the ratio of the second to third is 5/8.The second number is :a)15 b)20C)30 d)32e)33

Explanation:

Let the first number be =X1

and the second number be=X2

and the third number be =X3

given that =X1/X2=2/3

given that=X2/X3 =5/8

So,X1+X2+X3 =98.....

consider X1/X2=2/3

So,X1=2/3 X2....

consider X2/X3 = 5/8

write as 8X2 = 5X3

So,X3 =8/5 X2 ....

If we SUBSTITUTE 3,2,1

X1+X2+X3

2/3X2+X2+5/8X2 =98

X2 =(10+1+22 /15 ) =98

X2 = 30

Two parallel side of a trapezium are 60 cm and 77 cm and other sides are 25 cm and26cm. Find the area of the trapezium.​

Answer»

Answer:

Step-by-step explanation:

→ Draw a line BC PARALLEL to AD 

→ Draw a perpendicular line BE on DF

→ ABCD is a parallelogram.

→ BC=AD=25cm

→ CD=AB=60cm

→ CF=77-CD=17cm

→ For Δ BCF

⇒ perimeter of TRIANGLE=(25+26+17)/2

=68/2=34

⇒ By HERON's Formula of triangle=√s(s-a)(s-b)(s-c)

=√34(34-25)(34-26)(34-17)

=204cm²

⇒ Now area of ΔBCF=1/2xbase X height

=1/2 BExCF204cm²

=1/2x BEx17BE

=408/17

=24cm

⇒ Area of Trapezium =1/2(AB+DF)xBE

=1/2(60+77)x24

=1644cm²

Find the value of Sin(45-alpha) - cos (45+alpha)Need the answer as soon as possible

Answer»

sin(45-X) - cos(45+x)

We know,

Sin(theta) = cos(90°-theta)

So,

sin(45-x) -cos(45+x)

=>cos(90-(45-x) -cos(45+x)

=>cos(90-45+x) - cos(45+x)

=>cos(45+x)-cos(45+x)

=>0

{I have taken x in PLACE of ALPHA}

So,

sin(45-alpha)-cos(45+alpha)= 0

Cheers!

Simplest rationalizing factor of 3root 500

Answer»

Answer:

2

Step-by-step explanation:

Cube root of 500

= cube root of (5 x 5 x 5 x 2 x 2)

= 5 x cube root of (2 x 2)

Hence to rationalize cube root of 500, we REQUIRE another cube root of 2 i.e., 2 ^1/3.

Hence the SIMPLEST rationalising FACTOR of cube root of 500 is cube root of 2.

By celling 6 dozen of eggs a shopkeeper gains the selling price of a dozen of eggs .Find the gain %

Answer»

Answer:

16.66%

Step-by-step explanation:

LET CP be 100

cp of 6 DOZEN is ₹100

cp of 1 dozen is ₹100/6=50/3

Then SP is 100 + 50/3=350/3

gain is SP-CP

350/3-100=50/3

Gain% is (50/3)/100×100

=50/3=16.66%

What is the remainder when 77,777... up to 56 digits is divided by 19?

Answer»

Answer:

Let, N= 77…(37times)

Note: If a NATURAL number X = 19M + n where m,n BELONGS to natural numbers then

X mod 19 = n mod 19

WKT

N= 7(10^37–1)/9

=> 9N=7(10^37–1)

now,

N mod 19= (9N mod 171)/9 [ 9 divides 9N]

we have,

9N = 7[10{(1026–26)^12}-1]

therefore 9N mod 171= 7[10{26^12}-1] mod 171

[ removing terms which are divisible by 171 in the binomial expansion of (1026–26)^12]

=> 26^12=(684–8)^6

=>9N mod 171 = 7[10{8^6}-1] mod 171

=> 8^6=(513–1)^2

=> 9N mod 171 = 7[10{1}-1] mod 171 =63

therefore,

N mod 19 = 63/9 = 7

Hence the answer is 7

N a rhombus abcd, measure of angle cab is 25 , what is the measure of angle abc?

Answer»

Step-by-step explanation:

In a rhombus ABCD measure of ANGLE cab is 25 then measure of angle abc

∠CAB = 25°

in Δ ABC

AB = BC  ( all sides of a rhombus are EQUAL)

AC is Diagonal

as AB = BC  

=> ∠CAB = ∠ACB

=> ∠ACB = 25°

in Δ ABC

∠CAB + ∠ABC + ∠ACB = 180°

=> 25° +  ∠ABC +  25 = 180°

=> ∠ABC = 130°
