Answer: 2/9 meter

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. First, make an equation.

Given:

8/9 = length of wire

2/3 = length of a part of the wire

E = 8/9-2/3

Unknown:

Second part of wire

2. Make the numbers have equal denominators

2/3 * 3/3

= 6/9

3. Solve

8/9 - 6/9

= 2/9

Answer:

[tex]2x-5y=-40\\-5y = -40-2x\\y = \frac{-40}{-5}-\frac{2x}{-5} \\y = \frac{2x}{5}+8[/tex]

Slope of a line perpendicular is  [tex]\frac{-5}{2}[/tex]

Step-by-step explanation:

Hey there!

The given equation is ; 2x - 5y = -40.

Or, 2x - 5y + 40 = 0

Slope of the equation is;

[tex]slope(m) = \frac{ - coeff. \: of \: x}{coeff. \: of \: y} [/tex]

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

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

Therefore, the slope of equation is 2/5.

Now; For the perpendicular lines:

Slope of equation * slope of next line = -1

i.e M1*M2= -1

[tex] \frac{2}{5} \times m2 = - 1[/tex]

[tex]2 \: m2 = - 5[/tex]

[tex]m2 = \frac{ - 5}{2} [/tex]

Therefore, the slope of the line which is perpendicular line to 2x - 5y + 40= 0 is -5/2.

Hope it helps....

The area of the circle of diameter BC is the amount of space on the circle

Using the assumed value, the area of the circle is 19.625

The circle is not given.

So, I will assume a value for length BC

Assume the length of BC is:

BC = 5

The area of the circle would be:

[tex]Area = \pi (\frac{BC}{2})^2[/tex]

So, we have:

[tex]Area = 3.14 * (\frac{5}{2})^2[/tex]

Evaluate the product

[tex]Area = 19.625[/tex]

Using the assumed value, the area of the circle is 19.625

Answer: 12m by 4m.

Step-by-step explanation: You are looking for the dimensions of the room here, also known as the length and width.

Let’s make width equal to x since we don’t know what the value is. Length is going to be x + 8 since the diagonal is 8m MORE than the width.

w = x

l = x + 8

Use the equation for the perimeter.

P = 2l + 2w

Plug in your values:

32 = 2(x + 8) + 2(x)

Now, solve for x! First start by distributing the 2:

32 = 2x + 16 + 2x

Next, add like terms:

32 = 4x + 16

Subtract 16 from both sides:

16 = 4x

Divide by 4 on both sides:

4 = x

Now we have x, but remember, x is equal to the width. We just solved for width so now we need length.

l = x + 8

Plug in your x and solve:

l = 4 + 8

l = 12

Your length is 12m and your width is 4m, therefore, the dimensions of the rectangular room are 12m by 4m.

Step-by-step explanation:

The required proportion of red drum fish would be 0.2830 between 22 and 23.5 inches in length.

A Z-score is defined as the fractional representation of data point to the mean using standard deviations.

As per the given condition, if the fish is between 22 and 23.5 inches,

P(22≤ X ≤ 23.5)

You can rewrite it as:

⇒ P(X ≤ 22) - P(X ≤ 23.5)

The first step is to standard both values before using population data and the standard normal distribution to get the probability:

The formula of the standard normal is Z=(X-μ)/σ

⇒ P(Z ≤  (23.5-24)/1.4) - P(Z ≤ (22-24)/1.4) = P(Z ≤-0.36) - P(Z ≤ -1.43)

Now you look at the table of the Z-distribution for the cumulative probabilities for both z-score

⇒  (1 - 0.6406) - (1 - 0.9236)

⇒ 0.3594- 0.0764 = 0.2830

Hence, the required proportion of red drum fish would be 0.2830 between 22 and 23.5 inches in length.

Answer:

Step-by-step explanation:

Since the point A that is enclosed in the circle is on negative 5 (i.e -5 ) and point B appears to be located on positive 1 (i.e +1), hence the distance between points A and B is expressed as B - A

BA = A-B

Given

B = -5

A = +1

BA = 1-(-5)

BA = 1+5

BA = 6units

Hence the distance between points A and B is 6units
