Given the length and perimeter, the width of the rectangle is 38 inches.

Hence, option A) 38inches is the correct answer.

The perimeter of a rectangle is expressed mathematically as;

P = 2( l + w )

Given the data in the question;

Let "x" represent the width of the rectangle.

To determine the width of the rectangle, plug the given values into the formula above and solve for x.

P = 2( l + w )

220  = 2( (2x - 4) + x )

220 = 2( 2x - 4 + x )

220 = 2( 3x - 4 )

Apply distributive property

220 = 2( 3x - 4 )

220 = 2(3x) + 2(-4)

220 = 6x - 8

Collect like terms

220 + 8 = 6x

228 = 6x

6x = 228

x = 228/6

x = 38

Now, since "x" represent the width of the rectangle,

The width of the rectangle w = x = 38 inches.

Given the length and perimeter, the width of the rectangle is 38 inches.

Hence, option A) 38inches is the correct answer.

The time taken to hit the ground is 13 seconds.

It should be noted that the function that was given based on the information is:

where h = height

t = time

Therefore, when the height is 2704ft, the time will be:

h(t) = 16t²

2704 = 16t²

t² = (2704 / 16)

Step-by-step explanation:

This is the ratio of the lengths of the sides of a 45-45-90 triangle.

Time required to form 3,000,000 bacteria from 10 if it will double every hour = 18.2years.

The phrase exponential refers to a high number expressed in smaller terms, or something that grows at an ever-increasing rate. 25 is shown as 5x5 as an example of an exponential. The erosion that is occurring on the Holderness coast in eastern England is an example of exponential erosion.

Using the formula of exponential growth:

y = a*b^t

a = reflects the initial bacterial population

t =  represents the doubling.

the information given

a = 10

t = 1 hour

After 1 hour, the number of bacteria multiplies by 2, so:

y = 2 × 10 = 20

So that:

20 = 10 × b^1

Dividing through by 10 gives:

2 = b

solving this we get an equation:

y = 10(2)^t

Solving for 3,000,000 bacteria.

Substituting the value in the formula:

3000000 = 10(2)^t

3000000/10 = (2)^t

300000 = (2)^t

Applying the log of both sides, it gives:

Log 300000 = tlog2

5.477 = 0.301t

t = 5.477/0.301

t = 18.2 years

Time required to form 3,000,000 bacteria from 10 if it will double every hour = 18.2years.

The square root of 60 minus 11 would be plotted on a number line in between −3 and 8, but closer to 8.

A straight line with numbers placed at equal intervals or segments along its length. Number line is a straight line with a "zero" point in the middle, with positive and negative numbers listed on either side of zero and going on indefinitely.

Given:

The square root of 60 minus 11 would be plotted on a number line.

According to given question we have

We know that the  square root of 60

=

[tex]\sqrt{60} \\\\=7.74[/tex]

So, By the statement square root of 60 minus 11 we have,

=7.74-11

=-3.25

So, in the number line the points are lies in between −3 and 8, but

closer to 8.

Therefore, the square root of 60 minus 11 would be plotted on a number line in between −3 and 8, but closer to 8.

Answer: 195

Step-by-step explanation:

65%=65/100

300 * 65/100=

300 * 6.5/10=

300 * 13/20=

3900/20=

390/2=195

Solving the problem as per a linear equation, it can be proved that q = r.

A linear equation is an algebraic equation in the form of y = mx+ b. The highest power of a variable in a linear equation is always 1. Such equations always form a straight line on the graph.

From equation 1 we can write,

2q - r = 4p.................(1)

or, 2q - 4p = r ( side switched ) ................(2)

Now, 2p = r

or, 4p = 2r and we know 2r = q

Hence, we can write 4p = q ...............(3)

If we put equation (3) in (1)

we will get, 2q - q = r

or, q = r

q = r is proved.

The constant of proportionality for the ratio of green team students to gray team students is 7/8.

Ratio is the relationship between two quantities, normally expressed as the quotient of one divided by the other.

It can be expressed in different ways:

1) Use the ":" to separate the values : a : b

2) Use the word "to" : a to b

3) Write it in fraction: a / b

The ratio that relates two given values is called the constant of proportionality, a/b.

If the green team has 42 students, and the gray team has 48 students, then the ratio of green team students to gray team students can be written as:

42 : 48 or 42 to 48 or 42/48

To simplify the ratio, divide both numbers in the ratio by the same number until they cannot be divided any more.

Divide both number by 6.

42 : 48 = 7 : 8 or 7/8

Hence the constant of proportionality is 7/8.

Rebeeca’s histogram most likely shape will be Skewed to the left.

The histogram shows a symmetrical data distribution. A distribution is symmetrical if a vertical line can be drawn at any point in the histogram such that the shapes to the left and right of the vertical line are mirror copies of each other.

The mean and the median both reflect the skewing, but the mean reflects it more so. This is because the mean and median are measures of central tendency. Because in Rebecca’s data the mean is smaller compared to the median, it makes the histogram skewed to the left. If the median were to be smaller than the mean, it would be skewed to the right.
