Answer:

A  Open circle at 6, line going to the right

Step-by-step explanation:

The area of a rectangle is given by

A = l*w

We know the area is greater than 24

24 < l*w

One dimension is 4

24 < 4*w

Divide each side by 4

24/4 < 4w/4

6 < w

The other dimension must be greater than 6

Open circle at 6, line going to the right

I'm going to assume that you meant y = mx + b not y = my + b

To do this move 7x to the right side by subtracting it to both sides

(7x - 7x) - y = 8 - 7x

0 - y = 8 -7x

-y = 8 - 7x

Y still isn't full isolated! There is still the negative sign that you have to get rid of. To do this divide -1 to both sides

-y/-1 = (8 - 7x)/ -1

y = -8 + 7x

y = 7x - 8

Answer:

One of the many reasons of this is because the diet soda is less dense than the normal soda, therefor, it will float even though there's the same amount of liquid in each can, and the cans weigh the same amount

I hope this helps

Step-by-step explanation:

Answer:

The options in the question are missing, but the answer is "The can of diet soda will float due to the Archimedes principle.

Step-by-step explanation:

Now, Archimedes Principle can be defined as,

when a body is partially or completely immersed in a fluid, the body losses its weight in the fluid equal to the amount of fluid displaced by this body.

Notice that the phenomena of floating and sinking is based on Archimedes principle. If, the weight of body is higher than the amount of liquid it displaced, body will sink and if the weight of body is lower than the amount of liquid it displaced, then it will float. Now, in comparison of regular can with diet can, one needs to notice that diet can is slightly lighter due to absence of sugar in the liquid it contained. But the volume of both regular and diet can are same. When immersed, both displace same amount of water, but the weight of diet can is slightly lesser than the amount of water it displaced, so it floats, while on the other hand, the weight of normal can is slightly higher than the amount of water it displaced, so it sinks.

Here,

[tex]1.578 \times {10}^{ - 5} miles = 1 \: inches \\ 1 \: miles = \frac{1}{1.578 \times {10}^{ - 5} } \: inches\\ 1425 \: miles = \frac{1}{1.578 \times {10}^{ - 5} } \times 1425 inches\\ = 9.03 \times {10}^{7} inches[/tex]

Answer:

ROI = 66.67%

Step-by-step explanation:

Given:

josh investment= $12,000

Received sum= $20,000

ROI=?

ROI is the return on investment that gives the loss or gain in any investment and is calculated by the following formula:

ROI= (interest/investment) x 100

Finding interest:

interests= received sum- investment

              = 20,000-12,000

              =8000

Putting values in ROI formula we get:

ROI= (8000/12000) x 100

      = 66.67%

Hence the return on investment is 66.67%!

Answer:

[tex]w=11[/tex]

Step-by-step explanation:

we have

[tex]5=w/2.2[/tex]

Solve for w

That means----> isolate the variable w

Multiply by 2.2 both sides

[tex](2.2)*5=(2.2)*w/2.2[/tex]

Simplify

[tex]11=w[/tex]

Rewrite

[tex]w=11[/tex]

The solution to the equation 5 = w/2.2 is 11

From the question, we have the following parameters that can be used in our computation:

5 = w/2.2

Rewrite the equation as follows

w/2.2 = 5

So, we have

w = 5 * 2.2

Evaluate the product of 5 and 2.5

So, we have

w = 11

Hence, the solution to the equation is 11

Answer:

[tex]\sum_{n=4}^{15}4(-3)^{n-1}[/tex]

Step-by-step explanation:

The given sequence is 4, -12, 36

We can see there is a common ratio

[tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{-12}{4}=(-3)[/tex]

[tex]\frac{a_{2} }{a_{3} }[/tex] = [tex]\frac{36}{-12}=(-3)[/tex]

Therefore, the given sequence is a geometric sequence.

Now we have to determine the sigma notation of the sum for term 4 through term 15.

Since explicit formula of the sigma can be represented as

[tex]T_{n}=a(r)^{n-1}[/tex]

where [tex]T_{n}[/tex] = nth term

a = first term

n = number of term term

r = common ratio

and sum is denoted by [tex]\sum_{n=1}^{n}a(r)^{n-1}[/tex]

Now for the given sequence sigma notation will be

The solution to the system of equations is: [tex]\[x = 2.2, \quad y = 2.457\][/tex]

To solve the system of linear equations:

[tex]\[12x - 14y = -8\]\[-8x - 14y = -52\][/tex]

We can use the method of elimination to find the values of x and y.

First, let's eliminate y by subtracting the second equation from the first equation. Before that, we should multiply the equations to have the same coefficients for y with opposite signs:

Multiply the first equation by 1:

12x - 14y = -8

Multiply the second equation by -1:

8x + 14y = 52

Now, add the two equations:

[tex]\[(12x - 14y) + (8x + 14y) = -8 + 52\][/tex]

Simplifying this, we get:

[tex]\[20x = 44\]Solve for \(x\):\[x = \frac{44}{20}\]\[x = \frac{22}{10}\]\[x = 2.2\][/tex]

Now that we have x, we can substitute this value back into one of the original equations to find y. Using the first equation:

12x - 14y = -8

Substitute x = 2.2:

[tex]\[12(2.2) - 14y = -8\]\[26.4 - 14y = -8\][/tex]

Subtract 26.4 from both sides:

[tex]\[-14y = -8 - 26.4\]\[-14y = -34.4\][/tex]

Divide both sides by -14:

[tex]\[y = \frac{-34.4}{-14}\]\[y = 2.4571 \approx 2.457\][/tex]

Thus, the solution to the system of equations is:

[tex]\[x = 2.2, \quad y = 2.457\][/tex]

To ensure accuracy, let's substitute x and y back into the original equations and verify that they hold true.

Check the first equation:

[tex]\[12(2.2) - 14(2.457) = -8\]\[26.4 - 34.398 = -8\]\[-7.998 \approx -8 \quad \text{(approximately correct)}\][/tex]

Check the second equation:

[tex]\[-8(2.2) - 14(2.457) = -52\]\[-17.6 - 34.398 = -52\]\[-51.998 \approx -52 \quad \text{(approximately correct)}\][/tex]

Answer:

4 feet

Step-by-step explanation:

It is given that:

• At 2:30 p.m., the water depth was 2.6 feet.  

• It is now 5:00 p.m., and the depth of the water is 3.6 feet.

So in 2.5 hours ( 5pm - 2:30pm) the water rose 1 feet (3.6 - 2.6).

Now we can find how much water rises in 1 hour by setting up a ratio (let x be the depth increase of water in 1 hr):

[tex]\frac{2.5}{1}=\frac{1}{x}\\2.5x=1*1\\2.5x=1\\x=\frac{1}{2.5}\\x=0.4[/tex]

So, in 1 hour, the water level will rise 0.4 feet

So, at 6pm (1 hour from 5 pm) it will rise to 3.6 + 0.4 = 4 feet

The depth of the water is increasing at a rate of 0.4 feet per hour, so by 6:00 p.m., the depth will be 4 feet.

We are given the information that water is being pumped into a cylindrical tank and the height of the water increases linearly over time. At 2:30 p.m. the depth was 2.6 feet, and at 5:00 p.m. it was 3.6 feet. To find the rate of change in height, we need to first calculate the time difference and the change in height of the water:

Dividing the change in height by the time gives us the rate of change, which is 0.4 feet per hour (1 foot / 2.5 hours). Now we use this rate to predict the height at 6:00 p.m., which is one hour after 5:00 p.m.:

Depth at 5:00 p.m. = 3.6 feet + (0.4 feet per hour * 1 hour) = 4 feet.

Therefore, the expected depth of the water at 6:00 p.m. is 4 feet.

Answer:

The best measure of location or center is the median.

The best measure of spread or dispersion is the interquartile range (I.Q.R).

Step-by-step explanation:

The data set is skewed to the left since most of the data values fall in the upper end of the distribution. In other words the data set is negatively skewed since it is tailed to the left.

For any skewed data set;

The best measure of location or center is always the median. This is because the median is robust to outliers unlike the mean.

On the other hand, the best measure of spread or dispersion is the interquartile range (I.Q.R).

6x log (4)

Answer:

$2.04

Step-by-step explanation:

Note that: 1 yard = 3 feet.

First, change the amount of yard (6) to feet:

6 x 3 = 18

6 yard = 18 feet.

Note: 18 feet = $36.72

Find the cost per foot (1 feet). Note the equal sign, what you do to one side, you do to the other. Divide 18 from both sides.

(18 ft)/18 = ($36.72)/18

1 ft = 36.72/18

1 ft = 2.04/1

1 ft = $2.04

Answer: f(x^-1) = x/5 - 3/5

Step-by-step explanation:

1. Replace f(x) with y

2. Swap the positions of x and y to make x = 5y + 3

3. Solve for y by subtracting 3 from both sides and dividing each side by 5

The inverse of the function is f(x) = (x-3)/5 if the function f(x) is 5x +3 by taking the subject as x in the parent function.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

We have a function:

f(x) = 5x+3

To find the inverse of the function, take the subject x and the value of x.

f(x) - 3 = 5x

x = (f(x) - 3)/5

Replace the f(x) →x and x →f(x)

f(x) = (x-3)/5

Thus, the inverse of the function is f(x) = (x-3)/5 if the function f(x) is 5x +3 by taking the subject as x in the parent function.

The correct option is the second option:

(3, 11) because both lines pass through this point

To find which statement shows the solution to the system of equations, we need to find which of the given points are solutions to the system of equations. We must remember that if a point is a solution to a system of equations, it will satisfy both equations.

So, we are given the lines:

Line C

[tex]y=x+8[/tex]

Line D

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

Now, evaluating the first point to see if satisfies the line equations:

Evaluating (3,11)

Line C

[tex]11=3+8[/tex]

[tex]11=11[/tex]

We have that the point (3,11) satisfy the equation of the Line C, so, the linea pass through this point.

Line D

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

[tex]11=3*3+2[/tex]

[tex]11=11[/tex]

We have that the point (3,11) satisfies the equation of the Line C, so, the linea pass through this point.

Hence, we have that the points satisfies both lines, so it's a solution to the system of equation.

So, the correct option is the second option:

(3, 11) because both lines pass through this point
