A l-meter steel rod is bent into a rectangle so that its length exceeds quadruple its width
Dmitry_Shevchenko [17]

Answer:

The dimensions of the newly formed rectangle is length is 41 cm and width is 9 cm.

Step-by-step explanation:

Given,

A 1 meter steel rod is bent into a rectangle.

That means the perimeter of the rectangle is 1 meter.

So, Perimeter = 1\ m=100\ cm

Let the width of the rectangle be 'x'.

Now According to question, length exceeds quadruple its width by 5 cm.

Hence framing the above sentence in equation form, we get;

Length=4x+5

Now we use the formula of  perimeter of rectangle,

Perimeter=2(Length+width)

On substituting the values, we get;

2(4x+5+x)=100\\\\(5x+5)=\frac{100}{2}\\\\5x+5=50\\\\5x=50-5\\\\5x=45\\\\x=\frac{45}{5}=9

Now, we substitute the value of x to get the value of length;

Length=4x+5=4\times9+5=36+5=41\ cm

Thus, Width=9 cm    Length=41 cm

Hence the dimensions of the newly formed rectangle is length is 41 cm and width is 9 cm.

Write the equation of the linear relationship in slope-intercept form, using decimals as needed.
Vedmedyk [2.9K]

Answer:

y = -0.3x + 103

Step-by-step explanation:

✔️Find the slope (b):

Slope = ∆y/∆x

Using, (25, 95.5) and (35, 92.5),

Slope (m) = (92.5 - 95.5)/(35 - 25) = -3/10 = -0.3

✔️Find the y-intercept (b):

Substitute (x, y) = (25, 95.5) and m = -0.3 into y = mx + b

95.5 = -0.3(25) + b

95.5 = -7.5 + b

95.5 + 7.5 = b

103 = b

b = 103

✔️To write the equation, substitute m = -0.3 and b = 103 into y = mx + b

Thus:

y = -0.3x + 103
