Can someone show me how you get it and the answer

Answer:

---

Step-by-step explanation:

Convert the fraction to a decimal(40% = 40/100 = 0.4). Multiply it by 120.

0.4x120=a

The equation 40 ÷ 100 × 120 = a shows

the relationship 40% of 120 is a

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side).

'An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.'

For example, 3x + 5 = 15.

Given,

Relation, 40% of 120 is a

⇒ 40% × 120 = a

Above relation can be written in equation as

40 ÷ 100 × 120 = a

Hence, 40 ÷ 100 × 120 = a is the equation

for relation such that  40% of 120 is a.

Given:

The number is:

[tex]-(\dfrac{23}{47})[/tex]

To find:

The number that is equivalent to the given number.

Solution:

In option A,

[tex]-(-\dfrac{23}{47})=\dfrac{23}{47}[/tex]            [tex][\because (-)(-)=(+)][/tex]

In option B,

[tex]\dfrac{23}{-47}=-\dfrac{23}{47}[/tex]

In option C,

[tex]\dfrac{-23}{-47}=\dfrac{23}{47}[/tex]

In option D, we have

[tex]\dfrac{23}{47}[/tex]

The numbers in options A, C and D are equivalent to [tex]\dfrac{23}{47}[/tex]. So, options A, C and D are incorrect.

The numbers in options B is equivalent to [tex]-(\dfrac{23}{47})[/tex]. So, option B is correct.

Therefore, the correct option is B.

Answer:

[tex]g(x) = 4(x - 2)^2 -9[/tex]

Step-by-step explanation:

Given

[tex]g(x) = 4x^2 - 16x + 7[/tex]

Required

Complete the square

Rewrite so that [tex]x^2[/tex] has 1 coefficient

[tex]g(x) = 4(x^2 - 4x) + 7[/tex]

Take half of the coefficient of x

[tex]\frac{4}{2} = 2[/tex]

Square the result

[tex](\frac{4}{2})^2 = 2^2[/tex]

[tex](\frac{4}{2})^2 = 4[/tex]

Add and subtract the result in the bracket

[tex]g(x) = 4(x^2 - 4x + 4 - 4) + 7[/tex]

Expand the bracket to remove -4

[tex]g(x) = 4(x^2 - 4x + 4) - 16 + 7[/tex]

[tex]g(x) = 4(x^2 - 4x + 4) -9[/tex]

Expand the bracket

[tex]g(x) = 4(x^2 - 2x -2x+ 4) -9[/tex]

Factorize

[tex]g(x) = 4(x(x - 2) -2(x-2)) -9[/tex]

Factor out x - 2

[tex]g(x) = 4((x - 2)(x-2)) -9[/tex]

Express as square

[tex]g(x) = 4(x - 2)^2 -9[/tex]

Answer:

Step-by-step explanation:

6×y= 6y

x squared =x²

Answer:

let

hypotenuse[h]=60ft

base[b]=36ft

perpendicular [p]=48ft

by using Pythagoras law

p²+b²=h²

48²+36²=60²

2896≠3600

since p²+b²≠ h²[so the stage is not in a right angled triangle]but it is scalene triangle

Answer:

Step-by-step explanation:

This is because 2, 3, and 4 can all go into the number and it is the smallest of the ones listed.

Answer: 24

Step-by-step explanation:

1/2 x 12 = 12/24

2/3 x 8 = 16/24

3/4 x 6 = 18/24

Each number can be multiplied by "x" to get a denominator of 24.

Answer:

Common difference is 3. And the first term is 64.

Step-by-step explanation:

The differnce between 21 and 10 is 11. So there are 11 unknown numbers in between.  And the difference between 37 and 4 is 33. 33/11 is equal to 3. So the pattern is minus three. the first term is 9 terms before 37. 9 times 3 is 27. 37+27 is equal to 64. so the first term is 64

Step-by-step explanation:

Differentiate using the power rule

[tex]\frac{d}{dx}[/tex] (a[tex]x^{n}[/tex] ) = na[tex]x^{n-1}[/tex]

Given

y = [tex]\frac{3}{\sqrt{x} }[/tex] = 3[tex]x^{-\frac{1}{2} }[/tex] , then

[tex]\frac{dy}{dx}[/tex] = - [tex]\frac{3}{2}[/tex] [tex]x^{-\frac{3}{2} }[/tex] = - [tex]\frac{3}{2x^{\frac{3}{2} } }[/tex]

15+35

it help you

Answer:

C5(3+7)

Step-by-step explanation:

So, lets ingore the answers, and jsut try to break down 15+35

What can we take from both 15 and 35?

Well, 5 is the only one I can see in this.

So lets take 5 from this:

5(3 + 7)

We got 3 since 5x3 is 15, and we got 7 since 5x7 is 35.

So lets look at our answers and see if 5(3 + 7) is one of them

Well, looking at C, that is exactly 5(3 +7)

So c is our answer.

Hope this helps!
