A female grizzly bear weighs 500 pounds. after hibernating for 6 months, she only weighs 200 pounds. what is the mean change in weight per month

New Orleans has the lower elevation at -8 feet compared to Long Beach, which is at -7 feet, since a lower numerical value below zero indicates a further drop below sea level.

To determine which city has the lower elevation, we need to compare the elevations of Long Beach, California and New Orleans, Louisiana. A lower elevation means that it is further below sea level. Long Beach is at an elevation of -7 feet, while New Orleans is at 8 feet below sea level. In numerical terms, New Orleans’ elevation can be considered as -8 feet because the word 'below' indicates a negative elevation.

Comparing the two elevations:

Long Beach, California: -7 feet

New Orleans, Louisiana: -8 feet

Since -8 is less than -7, we determine that New Orleans has the lower elevation compared to Long Beach.

The form used  to write the equation of a line if you knew the slope and x-intercept y=mx−k/m

The slope of any line, ray, or line segment is the ratio of the vertical to the horizontal distance between any two points on it

According to the given situation we have given :a slope of 'm' and an x-intercept of 'k'

we can write

y=mx−k/m

and generally, To find the x-intercept, set y = 0 and solve for x.

For example,

Let k be some constant such that

y=mx + k

where

m is the slope.

m=3/4 and the x-intercept is 4

If the x-intercept is 4 this means that x=4 when y=0

So equation:

y=mx + k becomes

0=3/4+ k

k=−3

and our equation is

y=3/4x−3

Answer:

System of equation: 0.75(x+y)=120 and x-y=120

A is correct

Step-by-step explanation:

An aircraft travels with the wind for 120 miles in 0.75 of an hour.

The return trip is flown against the wind and takes exactly 1 hour.

Let speed of aircraft be x mph and speed of wind y mph

Formula:

[tex]speed=\dfrac{Distance}{Time}[/tex]

Case 1: When aircraft along with wind

Speed = x+y

Time = 0.75

Distance = 120

[tex]x+y=\dfrac{120}{0.75}[/tex]

[tex]0.75(x+y)=120[/tex]

0.75(x+y)=120

Case 2: When aircraft against with wind

Speed = x-y

Time = 1

Distance = 120

[tex]x-y=\dfrac{120}{1}=120[/tex]

x-y=120

Hence, The system of equation are 0.75(x+y)=120 and x-y=120

The width of the rectangle is 4.5 meters, and the length is 6 meters.

Let's denote the width of the rectangle as [tex]\( w \)[/tex] and the length as [tex]\( l \)[/tex].

1. The area [tex]\( A \)[/tex] of a rectangle is given by the product of its length and width, so we have the equation:

[tex]\[ A = l \times w \][/tex]

Since the area is given to be 27 square meters, we can write:

[tex]\[ l \times w = 27 \][/tex]

2. The length of the rectangle is 3 meters less than twice the width.

This relationship can be expressed as:

[tex]\[ l = 2w - 3 \][/tex]

This is our second equation.

Now we have a system of two equations with two variables:

[tex]\[ \begin{cases} l \times w = 27 \\ l = 2w - 3 \end{cases} \][/tex]

We can substitute the expression for [tex]\( l \)[/tex] from the second equation into the first equation:

[tex]\[ (2w - 3) \times w = 27 \][/tex]

Expanding the equation, we get:

[tex]\[ 2w^2 - 3w - 27 = 0 \][/tex]

To solve this quadratic equation, we can factor it:

[tex]\[ (2w - 9)(w + 3) = 0 \][/tex]

Setting each factor equal to zero gives us two possible solutions for [tex]\( w \)[/tex]:

[tex]\[ 2w - 9 = 0 \quad \text{or} \quad w + 3 = 0 \][/tex]

Solving for [tex]\( w \)[/tex], we get:

[tex]\[ w = \frac{9}{2} \quad \text{or} \quad w = -3 \][/tex]

Since the width of a rectangle cannot be negative, we discard [tex]\( w = -3 \)[/tex].

Thus, [tex]\( w = \frac{9}{2} \)[/tex] meters, which simplifies to [tex]\( w = 4.5 \)[/tex] meters.

Now we can find the length [tex]\( l \)[/tex] by substituting [tex]\( w = 4.5 \)[/tex] into the second equation:

[tex]\[ l = 2(4.5) - 3 \][/tex]

[tex]\[ l = 9 - 3 \][/tex]

[tex]\[ l = 6 \][/tex]

We do not square the deviations when calculating the average deviation, because the sum of all deviation scores around the mean equals zero.

It is the average value of the set given.

It is calculated as:

Mean = Sum of all the values of the set given / Number of values in the set

We have,

The average deviation is calculated by taking the absolute value of the deviations from the mean, summing them, and then dividing by the total number of observations.

This gives us a measure of the average distance between each observation and the mean.

The formula for the average deviation is:

average deviation = Σ |x - mean| / n

where x is an observation, mean is the mean of the observations, and n is the total number of observations.

By taking the absolute value of the deviations, we ensure that negative and positive deviations do not cancel each other out when we sum them.

Thus,

We do not square the deviations when calculating the average deviation, because the sum of all deviation scores around the mean equals zero.

Final answer:

To write each equation in slope-intercept form and identify the slope and y-intercept, rearrange the given equations. a) 2x - y = 4: slope = 2, y-intercept = -4. b) 2x - y = 0: slope = 2, y-intercept = 0. c) x + 3y = 0: slope = -1/3, y-intercept = 0. d) 2y - 6 = 0: slope = 0, y-intercept = 3.

Explanation:

The slope-intercept form of a linear equation is y = mx + b, where m represents the slope and b represents the y-intercept. To write each equation in slope-intercept form and identify the slope and y-intercept, we can rearrange the given equations.

a) 2x - y = 4
First, we rearrange the equation to isolate y: -y = -2x + 4, then we rewrite as y = 2x - 4. Therefore, the slope is 2 and the y-intercept is -4.

b) 2x - y = 0
Rearranging the equation gives y = 2x. The slope is 2 and the y-intercept is 0.

c) x + 3y = 0
Isolating y, we get y = -1/3x. The slope is -1/3 and the y-intercept is 0.

d) 2y - 6 = 0
Solving for y, we find y = 3. The slope is 0 and the y-intercept is 3.

(5y-3) = (3y+27)   -3y from both sides

2y-3 =  27    +3 to both sides

2y= 30   divide both sides by 2

y=15

check

5X15-3 = 3x15+27

72 = 72

correct that y=15 and that each angle is 72

in that shape correlating angles are the same so...

360-72-72= 216

216 divided by 2= 108 degrees

B is equal to 108 degrees

A is equal to 72 degrees

To find the rate of brain growth, we calculate the derivatives of the brain weight and body weight functions. Then, we find the rate by multiplying the derivatives and substituting the average length of 18cm. The rate of brain growth is approximately 0.04 grams/cm.

To find the rate at which the species' brain was growing when the average length was 18cm, we need to find the derivative of the brain weight function with respect to body weight and then multiply it by the derivative of body weight with respect to body length.

First, let's find the derivative of the brain weight function, b = 0.007w^(2/3), with respect to body weight, w.

Taking the derivative, we get db/dw = (2/3) * 0.007 * w^(-1/3).

Next, let's find the derivative of the body weight function, w = 0.12l^(2.53), with respect to body length, l.

Taking the derivative, we get dw/dl = 2.53 * 0.12 * l^(1.53).

Finally, to find the rate of brain growth when the average length was 18cm, we plug in the value 18 for l in the derivative of the body weight function and multiply it by the derivative of the brain weight function:

Rate of brain growth = (2/3) * 0.007 * (18)^(-1/3) * 2.53 * 0.12 * (18)^(1.53).

Rounding to the nearest hundredth, the rate of brain growth when the average length was 18cm is approximately 0.04 grams/cm.

The value of x is 72.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Let the integer be x and y.

An integer x is divided by an integer y, and the quotient is 24.

This can be written as:

x ÷ y
x/y = 24

x = 24y _____(1)

Now,

The sum of the integer is 75.

x + y = 75

From (1) we get,

24y + y = 75

25y = 75

Divide both sides by 25.

y = 3

Now,

From (2 ) we get,

x + y = 75

x + 3 = 75

Subtracting 3 on both sides.

x = 75 - 3

x = 72

We can also cross-check:

x = 72 and y = 3

= x ÷ y

= 72/3

= 24

Thus,

The value of x is 72.
