Answer:

P = (25.6g - 31.4)

Step-by-step explanation:

Given that,

The width of a rectangle = (8.1g−6.5) cm

The length of a rectangle, = (4.7g−9.2)

We know that,

The perimeter of a rectangle is given by :

P = 2(l+b)

Substitute all the values,

P = 2(8.1g−6.5+4.7g−9.2)

= 2(12.8g-15.7)

= 25.6g - 31.4

So, the perimeter of the rectangle is equal to (25.6g - 31.4).

Answer:

x = 70.53 degrees

Step-by-step explanation:

equation:

cos-1 = [tex]\frac{adjacent}{hypotenuse}[/tex]

⇒ cos-1 x = [tex]\frac{4}{12}[/tex]

⇒ cos-1 x = 0.33

⇒ x = 70.528

round to the nearest tenth:

⇒ 70.53

Answer:

[tex] - \frac{5}{2} [/tex]

Step-by-step explanation:

4x -10y= 40

Let's rewrite this equation in the slope-intercept form (y= mx +c) so that we can obtain it's slope.

10y= 4x -40

Divide both side by 10:

[tex]y = \frac{2}{5} x - 4[/tex]

The product of the gradients of perpendicular lines is -1.

⅖(gradient of line)= -1

Gradient of perpendicular line

[tex] = - 1 \div \frac{2}{5} [/tex]

[tex] = - 1 \times \frac{5}{2} [/tex]

[tex] = - \frac{5}{2} [/tex]

Answer:

n = 99

Step-by-step explanation:

The sum to n terms of an arithmetic sequence is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

Here a₁ = 1 , d = 2 and [tex]S_{n}[/tex] = 9801 , then

[tex]\frac{n}{2}[/tex] [ (2 × 1) + 2(n - 1) ] = 9801 ( multiply both sides by 2 to clear the fraction )

n(2 + 2n - 2) = 19602

n(2n) = 19602

2n² = 19602 ( divide both sides by 2 )

n² = 9801 ( take the square root of both sides )

n = [tex]\sqrt{9801}[/tex] = 99

The number of terms summed is 99

Answer:

7

Step-by-step explanation:

Let us say that [tex]y_{1}[/tex]= 5.5, [tex]x_{1}[/tex]= 11, and [tex]y_{2}[/tex] = 3.5.

[tex]\frac{y_{2}}{y_{1}} =\frac{x_{2}}{x_{1}}[/tex]

[tex]\frac{3.5}{5.5} =\frac{x_{2}}{11}[/tex]

[tex]\frac{7}{11} =\frac{x_{2}}{11}[/tex]

[tex]x_{2} =7[/tex]

I hope this is correct and helps you!

Answer:

8/9

Step-by-step explanation:

5a-3=a/2+1

2(5a-3)=a+2

10a-6=a+2

10-a=6+2

9a/9=8/9

a=8/9

Answer:

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angle.

146° is an exterior angle of the triangle, then

5y + 3 + 4y + 8 = 146

9y + 11 = 146 ( subtract 11 from both sides )

9y = 135 ( divide both sides by 9 )

y = 15

Then

∠ A = 5y + 3 = 5(15) + 3 = 75 + 3 = 78°

∠ B = 4y + 8 = 4(15) + 8 = 60 + 8 = 68°

∠ C = 180° - (78 + 68)° ← sum of angles in triangle = 180°

∠ C = 180° - 146° = 34°

Step-by-step explanation:

Incomplete question, as the number line is not attached. However, the solution is as follows:

Let y be the absolute value of -1/2 So:

[tex]y = |-\frac{1}{2}|[/tex]

The absolute sign removes all negation. So:

[tex]y = \frac{1}{2}[/tex]

This means that the point at the label [tex]\frac{1}{2}[/tex] or [tex]0.5[/tex] is the solution to the question.

Take for instance, the attached image has point Q at [tex]\frac{1}{2}[/tex].

Hence, Q is the absolute value of -1/2

Answer: 12 inches

Step-by-step explanation:

This is a square shaped mirror which means that it takes the shape of a square.

All sides on a square are equal and because the way the find the area of a square is to multiple the Length by the Width, you would be squaring the same number to find the area.

Length of each side = √area

= √144

= 12 inches

Given:

The expression is

[tex]3x^4-81x[/tex]

To find:

The product of prime polynomials which is equivalent to the given expression.

Solution:

We have,

[tex]3x^4-81x[/tex]

Taking out the common factors, we get

[tex]=3x(x^3-27)[/tex]

It can be written as

[tex]=3x(x^3-3^3)[/tex]

[tex]=3x(x-3)(x^2+3x+3^2)[/tex]        [tex][\because a^3-b^3=(a-b)(a^2+ab+b^2)][/tex]

[tex]=3x(x-3)(x^2+3x+3^2)[/tex]

[tex]=3x(x-3)(x^2+3x+9)[/tex]

Therefore, the correct option is B.

Answer:

It's B

Here is your answer!

= x + (x + 2) + 3(x + 2) = T

= (3x + 2) + (3x +6) = T

= 3x + 3x + 2 + 6 = T

= 6x + 8 = T

T = 5x + 8 is the formula for T expressed in terms of x.

A relationship between two expressions or values that is not equal to one another is referred to as "inequality" in mathematics. Therefore, an imbalance leads to inequity.

Given, Simon has x sweets. Yuen has 2 more sweets than Simon. Giulia has 3 times as many sweets as Yuen. Simon, Yuen, and Giulia have a total of T sweets.

From the given Data,

Thus, in Total sweets, Simon has = x

Total sweets Yuen have = x + 2

Total sweets Giulia have = 3*(x + 2 )

Since the total sweets all three have is T

Hence, T = x + x +2 + 3(x + 2)

T = x + x + 2 + 3x + 6

T = 5x + 8

Therefore, The formula for T in terms of x is T = 5x + 8

Answer:

Step-by-step explanation:

There are 13 hearts in 52 cards. C From above, P(Queen)=4/52 and P Heart=13/52, the queen of hearts is in both categories so we have to subtract 1/52 so we don't double count.
