a rectangles length is four feet more than its width write a quadratic function that expresses the rectangles area in terms of its width

Answers

Answer 1
Let's call the width: w and the length: L.

L = w + 4
Area = L x w

Substitute w+4 for L in the area equation.

So, Area = (w+4) x w
Rewritten as: w^2 + 4w

Write your answer as a percentage.

Answers

Answer:

50%                     1/2              3/6            0.5

Step-by-step explanation:

You can either get a 1, 2, 3, 4, 5, or a 6.

The factors of 8 include 1, 2, 4, 8.

There is only a matching 1, 2, and 4, but you cannot get any more factors. There are only 3 numbers out of a possible 6 number choices, so 3/6.

3/6 can be simplified to 1/2, and as a percentage, that is 50%.

Andy and Christopher are measuring a liquid solution using graduated cylinders, Andy uses 3.5 liters of the liquid solution, and Christopher uses 2,580 milliliters of the liquid solution. What is the ratio of Christopher's measurements to Andy's measurements in milliliters? One liter equals 1,000 millilters. Simplify your answer.

Answers

Answer:

[tex]Ratio = 0.74[/tex]

Step-by-step explanation:

Represent

- Andy with A

- Christopher with C

[tex]A = 3.5L[/tex]

[tex]C = 2580mL[/tex]

Required

Determine the ratio of C to A

Ratio is represented as thus:

[tex]Ratio = C:A[/tex]

Rewrite as fraction

[tex]Ratio = \frac{C}{A}[/tex]

This gives

[tex]Ratio = \frac{2580mL}{3.5L}[/tex]

Convert L to mL

[tex]Ratio = \frac{2580mL}{3.5*1000mL}[/tex]

[tex]Ratio = \frac{2580mL}{3500mL}[/tex]

[tex]Ratio = \frac{2580}{3500}[/tex]

[tex]Ratio = 0.73714285714[/tex]

What’s is the rate of change for the line that goes through the points (8,14) and (11,19.25)

Answers

Answer:

Rate of Change / Slope = 1.75 (or 7/4)

Step-by-step explanation:

Slope is Rise/Run which is (y2-y1)/(x2-x1). When we plug in both ordered pairs, we get (19.25-14)/(11-8)=5.25/3=1.75 as the slope.

The rate of change is the ratio of the rise and the run of the line. Hence, the rate of change of the line is 1.75

Rate of change = (Rise / Run)

Rise = y2 - y1 = (19.25 - 14) = 5.25

Run = x2 - x1 = (11 - 8) = 3

Rate of change = (5.25 / 3) = 1.75

Therefore, the rate of change for the line is 1.75

Let x and y be positive integers and x >y.

11

Answers

Complete Question:

Let x and y be positive integers and x be greater than y.

11x/11y = ?

Answer:

11x/11y = x/y

Step-by-step explanation:

Given

x > y

Required

11x/11y

From the question, we understand that x is greater than y (i.e. x > y)

Also, we'll assume that y ≠ 0, in other not to result in an undefined result.

So,

11x/11y

Divide the numerator and denominator by 11

(11x ÷ 11)/(11y ÷ 11)

The result of the division is:

(x)/(y)

x/y

Hence,

11x/11y = x/y for x > y and y ≠ 0

Step-by-step explanation:

Step 1: Define

Find points from chart.

Point (-4, 14)

Step 2: Find slope m

Answer:

[tex]\boxed {\boxed {\sf m=7}}[/tex]

Step-by-step explanation:

To find the slope, we can use the slope formula.

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

where (x₁, y₁) and (x₂, y₂) are points on the line.

We can pick any two points in the chart.

Let's use (-1, 35) and  (2,56).

If we use these points, then the variables are:

[tex]x_1=-1 \\y_1=35 \\x_2=2 \\y_2=56[/tex]

Substitute the values into the formula.

[tex]m=\frac{56-35}{2--1}[/tex]

Solve the numerator.

56-35=21

[tex]m=\frac{21}{2--1}[/tex]

Solve the denominator.

2--1= 2+1=3

[tex]m=\frac{21}{3}[/tex]

Divide.

[tex]m=7[/tex]

The slope of the line is 7

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as B

Now , the value of B is = number of boys

Substituting the values in the equation , we get

If three-fifths of the students are girls, then two-fifths must be boys, since the total fraction of students is equal to 1

On simplifying the equation , we get

To find the number of boys in the 7th grade, we can start by calculating the fraction of boys:

( 2/5 ) x 220 = 88

Hence , there are 88 boys in the 7th grade.

Since a square has 4 equal sides, it's safe to do [tex]\frac{52}{4}[/tex] to get each side length (each side is 13 mm).
