Does anyone know the solution of : 3(y+2)=2(y+4)

Answer»

Answer:

3(y+2)=2(y+4)

3y+6 = 2y+8

3y-2y = 8-6

1y = 2

so, 3(2+2) = 2(2+4)

Answer» Given : Length of the CUBOID = 15 cm BREADTH of the cuboid = 12 cm Height of the cuboid = 10 cm To find : Surface area of the cuboid Lateral surface area of the cuboid Length of the diagonal Solution : Surface area of the cuboid :- Formula to calculate surface area of the cuboid :- Surface area of cuboid = 2(lb + bh + hl) where, l denotes the length of the cuboid b denotes the breadth of the cuboid h denotes the height of the cuboid Substituting the given values, we GET :- → Surface area = 2(15 × 12 + 12 × 10 + 10 × 15) → Surface area = 2(180 + 120 + 150) → Surface area = 2(450) → Surface area = 900 ★ Surface area of the cuboid = 900 cm² Lateral surface area of the cuboid :- Formula to calculate lateral surface area of the cuboid :- Lateral surface area = 2h(l + b) Substituting the given values, we get :- → Lateral surface area = 2 × 10(15 + 12) → Lateral surface area = 20(27) → Lateral surface area = 540 ★ Lateral surface area of the cuboid = 540 cm² Length of the diagonal :- Formula to calculate length of diagonal of cuboid :- Length of diagonal = √(l² + b² + h²) Substituting the given values, we get :- → Length of diagonal = √(15)² + (12)² + (10)²) → Length of diagonal = √(225 + 144 + 100) → Length of diagonal = √469 → Length of diagonal = ± 21.65 As we KNOW, length of diagonal cannot be in negative. So, the negative sign will get rejected. → Length of diagonal = ± 21.65 Reject - ve → Length of diagonal = 21.65 ★ Length of the diagonal of cuboid = 21.65 cm

21958.

The dimensions of a cuboid are 15cm 12cm and 10cm then find i ) surface area ii)lateral surface area iii)length of diagonal

Answer»

Given :

Length of the CUBOID = 15 cm
BREADTH of the cuboid = 12 cm
Height of the cuboid = 10 cm

To find :

Surface area of the cuboid
Lateral surface area of the cuboid
Length of the diagonal

Solution :

Surface area of the cuboid :-

Formula to calculate surface area of the cuboid :-

Surface area of cuboid = 2(lb + bh + hl)

where,

l denotes the length of the cuboid
b denotes the breadth of the cuboid
h denotes the height of the cuboid

Substituting the given values, we GET :-

→ Surface area = 2(15 × 12 + 12 × 10 + 10 × 15)

→ Surface area = 2(180 + 120 + 150)

→ Surface area = 2(450)

→ Surface area = 900

★ Surface area of the cuboid = 900 cm²

Lateral surface area of the cuboid :-

Formula to calculate lateral surface area of the cuboid :-

Lateral surface area = 2h(l + b)

Substituting the given values, we get :-

→ Lateral surface area = 2 × 10(15 + 12)

→ Lateral surface area = 20(27)

→ Lateral surface area = 540

★ Lateral surface area of the cuboid = 540 cm²

Length of the diagonal :-

Formula to calculate length of diagonal of cuboid :-

Length of diagonal = √(l² + b² + h²)

Substituting the given values, we get :-

→ Length of diagonal = √(15)² + (12)² + (10)²)

→ Length of diagonal = √(225 + 144 + 100)

→ Length of diagonal = √469

→ Length of diagonal = ± 21.65

As we KNOW, length of diagonal cannot be in negative. So, the negative sign will get rejected.

→ Length of diagonal = ± 21.65 Reject - ve

→ Length of diagonal = 21.65

★ Length of the diagonal of cuboid = 21.65 cm

In the given figure altitudes AD and CE of triangle ABC intersect each other at the pointProve that B.AE×CP=CD×AP

Answer»

Given :-

In ∆ ABC

AD is altitude intersecting BC at D

CE is altitude intersecting AB at E.

Altitude AD and CE intersecting each other at P.

To Prove :-

AE × CP = CD × AP

Concept Used :-

Similarity of triangles.

Proof :-

It is given that

$\rm :\longmapsto\:CE \: \perp \: AB$

$\rm :\implies\:\angle \: CEA \: = \: 90 \degree \:$

$\rm :\implies\:\angle \: PEA \: = \: 90 \degree \:$

Also,

$\rm :\longmapsto\:AD \: \perp \: BC$

$\rm :\implies\:\angle \: ADC \: = \: 90 \degree \:$

$\rm :\implies\:\angle \: PDC \: = \: 90 \degree \:$

Now,

$\bf:\longmapsto\:In \: \<klux>TRIANGLE</klux> \: PEA \: and \: \triangle \: PDC$

$\rm :\longmapsto\:\angle \: PEA \: = \: \angle \: PDC \: \: \: \: \: \{each \: 90 \degree \}$

$\rm :\longmapsto\:\angle \: APE \: = \: \angle \: CPD \: \: \: \: \: \{vert. \: opp. \: angles\}$

$\rm :\implies\:\triangle \: PEA \: \sim \: \triangle \: PDC \: \: \{AA \: Similarity \: Rule \}$

$\rm :\implies\:\dfrac{EA}{DC} = \dfrac{AP}{CP}$

$\bf\implies \:AE \times CP = CD \times AP$

$\large{\boxed{\boxed{\bf{Hence, Proved}}}}$

Additional Information :-

1. Pythagoras Theorem :-

This theorem states that : In a right-angled triangle, the square of the longest side is equal to sum of the squares of REMAINING sides.

2. CONVERSE of Pythagoras Theorem :-

This theorem states that : If the square of the longest side is equal to sum of the squares of remaining two sides, angle opposite to longest side is right angle.

3. Area Ratio Theorem :-

This theorem states that :- The ratio of the area of two similar triangles is equal to the ratio of the squares of corresponding sides.

4. Basic PROPORTIONALITY Theorem,

If a line is drawn parallel to one side of a triangle, intersects the other two lines in distinct points, then the other two sides are divided in the same ratio.

Formulas of 1st to 8th standard

Answer»

Answer:

Maths Formulas For CLASS 8: Algebraic Identity

(a + b)2 = A2 + 2ab + b2

(a – b)2 = a2 – 2ab + b2

(a + b) (a – b) = a2 – b2

(X + a) (x + b) = x2 + (a + b)x + ab.

(x + a) (x – b) = x2 + (a – b)x – ab.

(x – a) (x + b) = x2 + (b – a)x – ab.

(x – a) (x – b) = x2 – (a + b)x + ab.

(a + b)3 = a3 + B3 + 3ab(a + b)

Answer» Answer: 1) 1 2)0 3)3 4)1 5)1 Step-by-step explanation: The branches of science, also referred to as sciences, "scientific fields", or "scientific DISCIPLINES," are commonly divided into three major groups: Formal sciences: the study of formal systems, such as those under the branches of logic and mathematics, which USE an a priori, as opposed to empirical, methodology. Formal sciences include mathematics, machine sciences (e.g. computer science), etc. Natural sciences: the study of natural phenomena (including cosmological, geological, physical, chemical, and biological factors of the UNIVERSE). Natural science can be divided into two main branches: physical science and LIFE science (or biological science).

2)0

3)3

4)1

5)1

Step-by-step explanation:

The branches of science, also referred to as sciences, "scientific fields", or "scientific DISCIPLINES," are commonly divided into three major groups:

Formal sciences: the study of formal systems, such as those under the branches of logic and mathematics, which USE an a priori, as opposed to empirical, methodology. Formal sciences include mathematics, machine sciences (e.g. computer science), etc.

Natural sciences: the study of natural phenomena (including cosmological, geological, physical, chemical, and biological factors of the UNIVERSE). Natural science can be divided into two main branches: physical science and LIFE science (or biological science).

Social sciences: the study of human behavior in its social and cultural aspects.[1]

The scale of the Universe mapped to branches of science and showing how one system is built atop the next through the hierarchy of the sciences.

Natural and social sciences are empirical sciences, meaning that the knowledge must be based on observable phenomena and must be capable of being verified by other researchers working under the same conditions.[2] This verifiability may well vary even within a scientific discipline[3][4]

Natural, social, and formal science make up the fundamental sciences, which form the basis of interdisciplinary and applied sciences such as engineering and medicine. Specialized scientific disciplines that exist in multiple categories may include parts of other scientific disciplines but often possess their own TERMINOLOGIES and expertises.[5]

Answer»

Answer:

RS. 308561.38 will be the final amount at the END of 5 years.

Step-by-step explanation:

By formula,

amount=p{[1+(r/100)]^n}

p= PRINCIPLE r=rate n=time period

as INTEREST is compounded annually, n=5

r=7 and p=220000

a=220000[1+0.07]^5

a=220000(1.40255)

Answer» LET the SIDES be 3x, 5X, 7x so, 3x + 5x + 7x = 300 X = 300/15 X = 20 so the sides are 3x = 60, 5x = 100 7x = 140 so area can be easily FOUND by herons formulae.

The sides of a triangle are in the ratio of 3 : 5 : 7 and its perimeter is 300 cm. Find Its area ?

Answer»

LET the SIDES be 3x, 5X, 7x

so, 3x + 5x + 7x = 300

X = 300/15

X = 20

so the sides are 3x = 60,

5x = 100

7x = 140

so area can be easily FOUND by herons formulae.
