Answer-So the dimensions of the rectangle are width is 4 m and length is 11 m

Step-by-step explanation:

Equation for Perimeter of a rectangle: Perimeter = 2W + 2L

Defining the variables, let

Width = x

Length = 2x+3 (3 more than twice the width)

Plugging everything into the equation

30= 2(x) + 2(2x+3)  using the distributive property,

30=2x+4x+6  combining like terms

30=6x+6  subtracting 6 from both sides,

24=6x  divide both sides by 6

4=x  This means that the width is 4 m

To get the length, use the expression L=2x+3 and plug in x = 4 that was already solved for

L=2(4)+3

L=8+3 = 11 m

So the dimensions of the rectangle are width is 4 m and length is 11 m

Answer: No real solutions.

Step-by-step explanation: −x2=8x+20

Step 1: Subtract8x+20  from both sides.

−x2−(8x+20)=8x+20−(8x+20)

−x2−8x−20=0

For this equation: a=-1, b=-8, c=-20

−1x2+−8x+−20=0

Step 2: Use quadratic formula with a=-1, b=-8, c=-20

Representing probability with area

When D= M-W =0, their heights are equal. When the man is taller, D is positive, and when the woman is taller, D is negative. Since we know the distribution of the difference D is normally distributed, the probability that the woman is taller than the man can be found by calculating the shaded area below D=0, in the corresponding normal distribution:

A standard normal curve is plotted on a horizontal axis representing D, that goes from negative 17 to 37. The mean, or mu sub D, = 10. The standard deviations, or sigma sub D = 9. The value 0 is marked. The area under the curve to the left of 0 is shaded, representing the probability that the woman is taller. The area to the right represents the probability that the man is taller.

normalcdf:

lower bound: −9999

upper bound: 0

μ=10

σ=9

​  

Using subtraction of normal variables, it is found that there is a 0.1335 = 13.35% probability that the woman is taller than the man.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem:

The probability of the women being taller is P(X > 0), which is 1 subtracted by the p-value of Z when X = 0.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{0 - (-10)}{9}[/tex]

[tex]Z = 1.11[/tex]

[tex]Z = 1.11[/tex] has a p-value of 0.8665.

1 - 0.8665 = 0.1335

0.1335 = 13.35% probability that the woman is taller than the man.

Answer:

[tex]\huge\boxed{y= \frac{1}{4}x+5}[/tex]

Step-by-step explanation:

In order to find the equation to this line, we have to note that with an incomplete equation, we can substitute in a point on the graph to find an unknown value.

The equation of a line is most commonly written in slope-intercept form, making it [tex]y=mx+b[/tex], where m is the slope and b is the y-intercept.

We know the y-intercept, which is 5, so our equation is currently [tex]y=mx+5[/tex].

We also know that the point (-4, 4) lies on this line. Therefore, we can plug it into our formula.

This means that the slope of our line is [tex]\frac{1}{4}[/tex]. Plugging that into our equation as m makes the final equation

[tex]y = \frac{1}{4}x + 5[/tex].

Answer:

no, three one way tickets are cheaper by 0.40 cents

Step-by-step explanation:

A Light Rail ticket in Baltimore for a one-way trip costs $1.60. Would it have been a better deal for Mr. K to buy the day pass at $5.20 if he needed to make 3 one way trips?

My explanation; 1.60+1.60= 3.20+1.60=4.80. so three one way trips will equal out to be 4.80, while a day pass is 5.20.

Answer:

80.64 is the area of the rectangle

Any vector that points in the same or opposite direction would be parallel. So you can just scale (-2, 3) by any real number t to get the vector (-2t, 3t ).

For example, if t = -1, you get the vector (2, -3); if t = 2, you get (-4, 6).

Answer:

x= -2

y= -4

Step-by-step explanation:

1) solve for y in 5x-y= -6

   which would be y= 5x+6

2) substitute that in for y in the second equation

    which would be 10x+3(5x+6)= -32

3) solve that new equation

    which would be x= -2

4) plug x= -2 into either equation (the shorter equation is the one i chose)

    which would be 5(-2) - y = -6

5) solve that new equation

  which would be y= -4

Step-by-step explanation:

40% = 0.4 = 4/10

The length is 20, 40% of that is (0.4)(20) = 8in

Length * width . = 20*8 = 160in²

The width of the rectangle is equal to 8 feet.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that the width of the rectangle is 40% of its length.

The width will be calculated as,

W = 0.4 x L

W = 0.4 x 20

W = 8 feet
