Answer» The algebra way Let the first NUMBER be n Then the SECOND number is n+1 The product is n×(n+1)=56 ⇒n2+n−56=0 Known: 7×8=56. However the equation's 56 is negative, so one of the 7 and 8 is negative. The equation has +n so the LARGER of the two is positive. Giving: (n−7)(n+8)=0 ⇒n=+7 and n=−8 As a first number n=−8 is not logical so the first number is n=7 Thus the second number is 8.

the product of 2 consecutive natural numbers is 56. solve this problem by using completing the square of quadratic equation. write the equation obtained after completing the square and also write the smaller of the 2 numbers. if you get the answer correct i shall mark you the brainiest

Answer»

The algebra way

Let the first NUMBER be n

Then the SECOND number is n+1

The product is n×(n+1)=56

⇒n2+n−56=0

Known: 7×8=56. However the equation's 56 is negative, so one of the 7 and 8 is negative.

The equation has +n so the LARGER of the two is positive. Giving:

(n−7)(n+8)=0

⇒n=+7 and n=−8

As a first number n=−8 is not logical so the first number is n=7

Thus the second number is 8.

Answer»

$\Large \fbox \red {Question \: :}$

What should be ADDED to the SUM of (-35) & 17 to GET (-70) ?

$\Large \fbox \red {Answer \: :}$

LET the number be x.

(-35 + 17) + x = - 70

-18 + x = - 70

x = - 70 + 18

x = - 52

$\implies$ - 52 should be added to the sum of (-35) & 17 to get (-70).

Answer» 3a +5b = 26 a +5b =22 This could be easily done by elimination method Now, if we multiply the SECOND equation by 3 then 3(a+5b)=3×22 3a+15b = 66 Now if we will SUBTRACT eq.1 from eq.2 then, one of the variable 'a' will get CANCELLED out, (3a+5b)- (3a+15b) =26 - 66 So 5b - 15 b= -40 -10b =-40 so b=4 THEREFORE 3a + 5× 4 =22 3a + 20 =22 so 3a = 2 so a =2/3

15014.

Solve the following simultaneous equations.(1) 3a + 5b = 26; a + 5b = 22

Answer»

3a +5b = 26

a +5b =22

This could be easily done by elimination method

Now, if we multiply the SECOND equation by 3 then

3(a+5b)=3×22

3a+15b = 66

Now if we will SUBTRACT eq.1 from eq.2 then, one of the variable 'a' will get CANCELLED out,

(3a+5b)- (3a+15b) =26 - 66

So 5b - 15 b= -40

-10b =-40

so b=4

THEREFORE 3a + 5× 4 =22

3a + 20 =22

so 3a = 2

so a =2/3

❐ A man standing on the deck of a ship, which is 10m above water level. He observes the angle of elevation of the top of a hill as 60° and the angle of depression of the base of the hill as 30°. Calculate the distance of the hill from the ship and the height of the hill.Answer with proper explanation.Kindly don't spam!

Answer»

Diagram

According to diagram the SHIP is at POINT A and the total height of the hill is (x+10)m

Given :-

Angle BAC = 60°
Angle ADE = 30°
CD = AE = 10 m

To Find :-

Distance of hill from Ship(AC or DE)

Height of the Hill ( BD )

Solution :-

For finding the distance of ship from the hill and height of hill we will use the trigonometric ratio,

Take Triangle AED to find distance of Ship from the hill

$\sf\mapsto{\tan( \theta )=\dfrac{Perpendicular}{Base}}$

$\sf\mapsto{\tan(30)=\dfrac{AE}{DE}}$

$\sf\mapsto{\tan(30)=\dfrac{10}{DE}}$

$\sf\mapsto{\dfrac{1}{\sqrt{3}}=\dfrac{10}{DE}}$

$\sf{\boxed{\boxed{\red{\dag{DE=AC=10\sqrt{3}m}}}}}$

So , the distance of ship from heel hill is 10√3 m

Take Triangle ABC to find the value of x

$\sf\mapsto{\tan(\theta)=\dfrac{Perpendicular}{Base}}$

$\sf\mapsto{\tan(60)=\dfrac{BC}{CA}}$

$\sf\mapsto{\tan(60)=\dfrac{x}{10\sqrt{3}}}$

$\sf\mapsto{\sqrt{3}=\dfrac{x}{10\sqrt{3}}}$

$\sf\mapsto{x= BC = 30m}$

Total height of Hill

$\implies\sf{BD = BC+CD}$

$\implies\sf{BD = 30+10}$

$\sf{\boxed{\boxed{\red{\dag{BD=40m}}}}}$

So , height of the hill is 40m
