. If x = 3 sec²0-1, y = tan²0 – 2 then find x - 3y.

Answer»

x-3y=-4

1. x-3y=3Sec²θ-1-3*(tan²θ-2)

x-3y=3Sec²θ-1-3tan²θ-6

x-3y=3*(Sec²θ-tan²θ)-7

x-3y=3*1-7       [Sec²θ-tan²θ=1]

In a class, the highest score is 91. If the highest score is twice thelowest score plus 11, find the lowest score.​

Answer»

Answer:

The lowest score of the exam was 40.

Step-by-step explanation:

It is PROVIDED that the highest score is twice the  lowest score PLUS 11.

The STATEMENT can be expressed as follows:

      Highest score = (2 × Lowest score) + 11

                          91 = (2 × Lowest score) + 11

(2 × Lowest score) = 91 - 11

       Lowest score = 80/2

                               = 40

Thus, the lowest score of the exam was 40.

four cubes of Edge 5 cm each are placed side by side and stuck together. if the outer surface alone is painted at rupees 300 per metre square, find the cost of painting . ​

Answer»

ANSWER:

If two cubes are joined, then the resultant SHAPE will be a cuboid and the length of that cuboid will be TWICE the EDGE of each cube,breadth and height are the edge of cube.

Therefore,the length of the cuboid(l)=2*5=10cm

Breadth of the cuboid(b)=5cm

Height of the cuboid(h)=5cm

Total SURFACE area of the cuboid=2[lb+bh+lh]

=2[(10*5)+(5*5)+(10*5)]

=2(50+25+50)

=2(125)

=250 sq.cm.

Cost of painting=250(300)=Rs.75,000.

16.

Two candidates contested from a constituency in an election the winner secured 68% of the votes polled if the difference between their votes was 23040 find the votes secured by the winner

Answer»

ANSWER:

Let the TOTAL votes be X.

68% of x = 68/100 × x =68/100x

it means , 68/100x + 23040 = x

23040 = x - 68/100x

23040 = 32x/100

23040 ×100 /32 = x

72000 = x

so 68% of x or 72000 = 48960

so the winner has won with 48960 votes.

speed = 3 km/h = 3*5/18 =5/6 m/s

time = perimeter of RECTANGLE /speed

    = 260/5/6 = 312 seconds

you did not MENTION units of rectangle. so, i took it in meter.

Find x if the following is in proportion/continued proportion in 48,60,x

Answer»

ANSWER:

x = 75

Step-by-step explanation:

We are GIVEN that 48,60,x is in proportion/continued proportion.

When THREE numbers a,B and c are in proportion then it is stated that;

                       b^{2} = a * c

So,  60 * 60 = 48 * x

                  x = \frac{60*60}{48}

                  x = 75

Therefore, value of x = 75.

The average age of three boys is 15 years and their ages are in tje ratio 3:5:7. Find the age of the youngest boy

Answer»

ANSWER:

let the age of first boy =3x

let the age of second boy =5x

let the age of THIRD boy = 7x

ACCORDING TO THE QUESTION

= 3x+ 5x+ 7x = 15

=15x=15

therefore, x = 15/15

x= 1

hence , the age of first boy = 3x =3×1 =3 years

the age of second boy = 5x = 5×1 = 5 yrs

the age of third boy = 7x =7×1 = 7years

so, the age of youngest boy = 3 years

if the difference between simple and compound intrest earned on a sum of money at 5% p.c.p.a. for 2 yrs is rs. 16 find the principal​

Answer»

ANSWER: marka sbrainliesta ND follow me

Step-by-step EXPLANATION: If the difference between compound and simple interest is of two years than,

Difference = P(R)²/(100)²

Where P = principal AMOUNT, R = rate of interest

If the difference between compound and simple interest is of three years than,

Difference = 3 x P(R)²/(100)² + P (R/100)³.

Here ALSO, P = principal amount, R = rate of interest

(111) Water is filled in a right cylindrical tank with base radius 14 cm, such that waterTevel is 3 cm below the top. When an iron ball is dropped in the tank, 3003 cmº ofwater flows out. Find the radius of the ball.​

Answer»

Answer:

Consider the provided information.

Radius of water TANK is 14 cm and water level is 3 cm below the top.

When iron ball is dropped it water 3003 cm³ of water flows out.

Volume of empty tank = \pi r^2 H

The volume of ball = Volume of empty tank + Volume of water came out

The volume of ball = \pi r^2 h + Volume of water came out

The volume of ball = \frac{22}{7}\times14^2\times3 + 3003 cm³

The volume of ball = 1848 cm³ + 3003 cm³

The volume of ball = 4851 cm³

The volume of sphere is: V=\frac{4}{3}\pi r^3

Substitute the respective values in the above formula.

4851 =\dfrac{4}{3}\TIMES\dfrac{22}{7}\times r^3

r^3= \dfrac{4851\times3\times7}{22\times4}

r^3=1157.625

r=10.5

Hence, the radius of the ball is 10.5 cm³.

if x is equals to root 3 + root 2 divided by root 3 minus root 2 and Y is equals to root 3 minus root 2 / 3 + root 2 find the value of x + y whole square​

Answer»

Step-by-step EXPLANATION:

x = √3 + √2 / √3 - √2

by RATIONALISATION,

x = (√3 + √2)² / 3 - 2

x = 5 + 2√6

similarly ,

y = 5 - 2√6

so, ( x + y )² = (5 + 2√6 + 5 - 2√6)²
