Answers

Answer:

41. D, 42. B, 43. A

Step-by-step explanation:

Sides are 120 m, 170 m, 250 m

41.

S is the semi-perimeter and is equal to:

s = (a + b + c)/2 = (120 + 170 + 250)/2 = 270 m

Correct choice is D

42.

The area is easy to calculate using the Heron's formula, since we have all three side lengths known.

Correct choice is B

43.

Perimeter is:

P = a + b + c = 120 + 170 + 250 = 540 m

Correct choice is A

£20 is divided between Colin, Dan & David so that Colin gets twice as much as Dan, and Dan gets three times as much as David. How much does Colin get?

Answers

Answer:

£12

Step-by-step explanation:

Let Colin - x, Dan - y, David - z.

We have:

x + y + z = 20x = 2yy = 3z

Substitute and solve for z:

2y + y + z = 203y + z = 203(3z) + z = 2010z = 20z = 2

Now find x and y:

y = 3*2 = 6x = 2*6 = 12

Answer:

£12

Step-by-step explanation:

Let the David's money be x

If David gets = x

Dan will get = 3x

Colin gets = 3x x 2

= 6x

So, the total money can be write as

[tex]x + 3x + 6x = 10x[/tex]

So, now let's find the amount of money which David have

[tex]10x = 20 \\ \frac{10x}{10} = \frac{20}{10} \\ x = 2[/tex]

So, David will get £2

And now let's find the amount of money which Colin will get

[tex]6x = 6 \times 2 \\ = 12[/tex]

He will get £12

Hope this helps you.

Hope this helps :)

Pls make brainliest :3

And have an amazing day <3

Answer:

128 pieces can be made after cutting the chain

Solution:

Given that, Amy cut 32 ft of chain into pieces that were each 1/4 ft long

To find: Number of pieces after cutting the chain

From given,

total length of chain = 32 feet

length of 1 piece = 1/4 feet

Thus the number of pieces after cutting the chain can be found by dividing the total length of chain by length of 1 piece

number of pieces = total length of chain/length of 1 piece

Substituting the values, we get

number of pieces = [tex]\frac{32}{1/4}[/tex]

number of pieces = 32 x 4 =128

Thus 128 pieces can be made after cutting the chain

A.5x^2 – 2x =
B.x^2 – 12x – 45 =
C.2x^2-x-15
D.9x^2-16

Answers

Answer:

See below

Step-by-step explanation:

5x² – 2x = x(5x - 2)

x² – 12x – 45 = x² + 3x - 15x - 45 = x(x + 3) - 15(x + 3) = (x + 3)(x - 15)

2x² - x - 15 = 2x² + 5x - 6x - 15 = x(2x + 5) - 3(2x + 5) = (2x + 5)(x - 3)

9x² - 16 = (3x)² - 4² = (3x + 4)(3x - 4)

Given :-

A.5x^2 – 2x = B.x^2 – 12x – 45 = C.2x^2-x-15 D.9x^2-16

To Find :-

Factorised form into two binomials .

Answer :-

A) 5x² - 2x

= x ( 5x -2 )

B) x² - 12x -45

= x² -15x + 3x -45

= x(x -15) +3( x -15)

= (x-15) ( x +3)

C) 2x² - x -15

= 2x² +5x - 6x -15

= x(2x +5) -3(2x +5)

= (x-3)(2x+5)

D) 9x² -16

=(3x)² -4²

= (3x+4)(3x-4) [using a²-b² = (a+b)(a-b) ]

Correct answer will be mark as brainliest.

Answers

Answer:

-2

Step-by-step explanation:

As per the provided information in the given question, we have a linear equation. We have to find the value of x.

Here, we'll use transposition method to solve this linear equation.

Basically, transposition method is used to solve a linear equation in one variable containing constants and variables. We just transpose the values from RHS to LHS by changing its arithmetic operators. In this way, we solve for the unknown value. During transposing the values, ( + ) changes to ( – ) and vice-versa ; ( × ) changes to ( ÷ ) and vice-versa.

Now, coming back to the question. We have,

[tex]\longmapsto \rm { 3x = \dfrac{x}{2}- 5} \\ [/tex]

Taking the LCM in RHS and performing subtraction.

[tex]\longmapsto \rm { 3x = \dfrac{x - 10}{2}} \\ [/tex]

Transposing 2 from RHS to LHS. Its arithmetic operator will get changed.

[tex]\longmapsto \rm { 3x \times 2 = x - 10} \\ [/tex]

Performing multiplication in LHS.

[tex]\longmapsto \rm { 6x = x - 10} \\ [/tex]

Transposing x from RHS to LHS. Its arithmetic operator will get changed.

[tex]\longmapsto \rm { 6x - x = - 10} \\ [/tex]

Performing subtraction of the terms in LHS.

[tex]\longmapsto \rm { 5x = - 10} \\ [/tex]

Transposing 5 from LHS to RHS. Its arithmetic operator will get changed.

[tex]\longmapsto \rm { x = \cancel{\dfrac{- 10}{5}}} \\ [/tex]

Dividing –10 by 5.

[tex]\longmapsto \underline{\boxed{\bf { x = - 2}}} \; \bigstar \\ [/tex]

Therefore, the value of x is –2.

[tex](-1{2}{3} )x^{3}[/tex]

Answers

After talking with you here are two different options I think you are trying to ask:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If you are talking about: [tex](\frac{-12}{3}) ^{3}[/tex]

Answer: -62

Explanation:

PEMDAS tells us we need to do the exponent first:

-12³ = (-12)³ = -1728

The parentheses are important so you cube the negative sign as well!

3³ = 27

-1728 / 27 = -62

[tex](\frac{-12}{3}) ^{3}[/tex] simplified is -62

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If you are talking about (-1[tex]\frac{2}{3}[/tex])³

Answer: -[tex]\frac{125}{27}[/tex]

Explanation:

First, let us turn -1 and two thirds into a mixed number:

Ignoring the negative for now, we can 1 times 3 is 3. 3 plus 2 is 5. 5/3 is 5/3. Adding in the negative we get [tex]-\frac{5}{3}[/tex]

To cube it we must do:

([tex]-\frac{5}{3}[/tex])([tex]-\frac{5}{3}[/tex])([tex]-\frac{5}{3}[/tex])

3 times 3 (9) times 3 is 27

5 times 5 (25) times 5 is 125

So we have 125/27

For the negative, we have three - - -

Two cancel each other out, and we are left with one (-) so our answer is negative

(-1[tex]\frac{2}{3}[/tex])³ simplifed is -[tex]\frac{125}{27}[/tex]
