Which expression is equivalent to the given expression [tex]\sqrt{45}[/tex]

Answer:

Evan could be thinking of 200,000.

The length and width of the rectangle is 23 and 11 cm.

Given, perimeter = 68 cm

A rectangle's perimeter P is determined by the equation P=2l+2w, where l is the rectangle's length and w is its width. In the formula A=lw, where l is the length and w is the width, the area A of a rectangle is determined.

let the width of the rectangle be x.

and length of the rectangle be 12 ₊ x

Formula of the perimeter = 2l ₊ 2w

68 = 2(12 ₊ x) ₊  2x

68 = 2x ₊ 24 ₊ 2x

68 ₋ 24 = 4x

44 = 4x

x = 44/4

x = 11

Hence the width of the rectangle is 11 cm and length:

12 ₊ x

= 12 ₊ 11

= 23 cm

Hence we get the length and width of the rectangle as 23 and 11 cm.

Answer:

22 and 23

Step-by-step explanation:

The first step is to make an equation that models this problem. Since the two numbers are consecutive, make them [tex]x[/tex] and [tex]x+1[/tex].

Since it says three times the larger number is 47 more than the smaller number, that means

[tex]3 (x+1) = x+47[/tex]

[tex]3x+3 = x+47[/tex]

[tex]2x+3=47[/tex]

[tex]2x=44[/tex]

[tex]x=22[/tex]

The smaller number is 22, and the larger number is 23.

Based on the fact that the model has a scale of 1/12, solving the equation of 12x = 86 to determine the tons of the completed sculpture gives 7 tons.

The model is said to have a scale of 1/12 of the original stone landmark which means that if the original famous landmark weighs 86 tons, the tons of the model can be found by the formula:

12x = 86

When solving for x which is the tons of the completed sculpture, the weight would be:

12x = 86

x = 86 / 12

x = 7 tons

In conclusion, the completed sculpture would weigh 7 tons.

Answer:

x - intercept; (80, 0)

y - intercept; (0, ∞)

Step-by-step explanation:

Let Week be w and Amount be A;

We see an inverse proportionality;

[tex]{ \rm{w \: \alpha \: \frac{1}{A } }} \\ \\ { \rm{w = \frac{m}{A} }}[/tex]

m is a constant of proportionality;

When w is 1, A = 68

[tex]{ \rm{ 1 = \frac{m}{68} }} \\ \\ { \rm{m = 68}}[/tex]

Therefore;

[tex]{ \tt{w = \frac{68}{A} + c }} \\ [/tex]

c is a constant;

When w is 0, A is 80

[tex]{ \rm{0 = \frac{68}{80} + c}} \\ \\ { \rm{c = - \frac{17}{20} }}[/tex]

Overall equation:

[tex]{ \rm{y = \frac{68}{x} + \frac{17}{20} }} \\ [/tex]

For x-intercept, y = 0

[tex]{ \rm{ \frac{17}{20} = \frac{68}{x} }} \\ \\ { \rm{x = 80}}[/tex]

For y-intercept, x = 0

y = ∞

Simplifying the given polynomial expression is; -(1/4)x³ - (7/2)x² + (214/16)x + (7/2)

We want to simplify the polynomial expression;

((1/2)x + 2)((1/2) - 2x) + ((1/4)x + (7/2))

Let us expand the first bracket to get;

((1/2)x * (1/2) + (2 * (1/2)) - ((1/2)x * 2x) - (2 * 2x))

⇒ (1/4)x + 1 - x² - 4x

⇒ 1 + (15/4)x - x²

Thus, our expression is now;

(1 + (15/4)x - x²)((1/4)x + (7/2))

This can be multiplied out to give;

(1/4)x + (15/16)x - (1/4)x³ + (7/2) + (105/8)x - (7/2)x²

= -(1/4)x³ - (7/2)x² + (107/8)x + (15/16)x + (7/2)

= -(1/4)x³ - (7/2)x² + (214/16)x + (7/2)

Answer:

One pen is $4.25 and one pencil is $1.85.

Step-by-step explanation:

Let cost of pens be x and cost of pencils be y.

1. 4x+3y=22.55

2. 3x+2y=16.45

Sub. 1.-2.,

x+y=22.55-16.45

x=6.1-y

Sub. x=6.1-y into 1.,

y=1.85

x=4.25

Answer:

Cost of a box of pens = $4.25

Cost of a box of pencils = $1.85

Step-by-step explanation:

Given information:

Define the variables:

Create two equations from the given information:

[tex]\textsf{Equation 1}: \quad 4x + 3y = 22.55[/tex]

[tex]\textsf{Equation 2}: \quad 3x + 2y = 16.45[/tex]

Multiply Equation 1 by 3:

[tex]\implies 3 \cdot 4x + 3 \cdot 3y = 3 \cdot 22.55[/tex]

[tex]\implies 12x + 9y = 67.65[/tex]

Multiply Equation 2 by 4:

[tex]\implies 4 \cdot 3x + 4 \cdot 2y = 4 \cdot 16.45[/tex]

[tex]\implies 12x + 8y = 65.80[/tex]

Subtract the equations to eliminate the term in x:

[tex]\begin{array}{r rr}& 12x+9y = &67.65\\- & 12x+8y = &65.80\\\cline{2-3} & y = & 1.85\end{array}[/tex]

Substitute the found value of y into one of the equations and solve for x:

[tex]\implies 3x + 2y = 16.45[/tex]

[tex]\implies 3x + 2(1.85) = 16.45[/tex]

[tex]\implies 3x + 3.7 = 16.45[/tex]

[tex]\implies 3x =12.75[/tex]

[tex]\implies x=4.25[/tex]

The slope of the line having points (3,135), (5,225), and (7,315) is 45

Slope:

The ratio of how much y grows as x grows by a certain amount is known as a line's slope. The slope of a line indicates how steep it is, or how much y rises as x rises. Anywhere along the line, the slope remains constant (the same).

The formula of slope for a line(m)=[tex]\frac{y2-y1}{x2-x1}[/tex]

Given the points  (3,135) , (5,225) and (7,315)

What in mathematics is a linear equation?

Let x = length of the sides of the base, and h = the height.  The volume is given as 9 m3

Volume = area of base * height

9 = x2*h

So 9/x2 = h

The surface area, S, of the box is:

S = (Area of Base) + 4*(Area of a Vertical Side)

S = x2 + 4 * (xh)
