Find the dimensions of a rectangle if the perimeter is 318 inches and the
length is half the width plus nine inches.

Answers

Answer 1

The dimensions of the rectangle are 59 by 50 inches

How to fnd the dimensions of a rectangle?

The given parameters are

Length (l) = 1/2 width (w) + 9

Perimeter (P) = 318

Perimeter is calculated as

P = 2 (l + w)

Substitute l = 1/2w + 9 in P = 2(l + w)

So, we have

2 * (1/2w + w + 9) = 318

Evaluate the like terms

2 * (1.5w + 9) = 318

Divide by 2

1.5w + 9 = 159

So, we have

1.5w = 150

Divide by 15

w = 100

Substitute w = 100 in l = 1/2w + 9

l = 1/2 * 100 + 9

Evaluate

l = 59

Hence. the dimensions of the rectangle are 59 by 50 inches

Here we can are first supposed to find the pattern which is as follows:

[tex]6-5=1\\14-6=8\\29-14=15\\51-29=22\\80-51=29\\[/tex]

Therefore difference between the numbers is 7 more than the previous one i.e,

The function which is not continuous is C. number of tennis balls that can fit completely inside a particular box as a function of the radius of the tennis balls.

We know that a function that does not have discontinuities in the values that means any changes in value.

a. your altitude as a function of time while flying from reno to Dallas.

c. number of tennis balls that can fit completely inside a particular box as a function of the radius of the tennis balls.

b. time of travel from Miami to Pensacola as a function of driving speed.

d. area of a circle as a function of radius.

We need to find a function which is not continuous.

The function which is not continuous is the statement C. number of tennis balls that can fit completely inside a particular box as a function of the radius of the tennis balls.

Because the number of these balls is discreet, not continuous (meaning that there cannot be 2.3 balls).

Answers

The number of trips max would have to make in order to deliver 12 cords of wood is 16 trips.

We will use unitary method to solve this problem.

Pick up truck carry ( 3/4 ) cord of firewood in trip = 1

Pick up truck will carry 1 cord of firewood in the trips =  ( 1/(3/4) ) trips                                                                                                                

                                                                                        = ( 4/3 ) trips

Truck will carry 12 cords of firewood in the trips = 12 × ( 4/3 )

                                                                                = 16 trips.

Answers

Based on the given parameters, the range of the function is -8 < y < -3

How to determine the range of the function?

We have the following endpoints on the graph of the function;

(x, y) = (-5, -3)

(x, y) = (10, -8)

A diagonal curve connects both points

Remove the x values to determine the range

y = -3

y = -8

-8 is less than -3

So, the range can be represented as

-8 less than y less than -3

Express less than using the inequality <

So, we have

Range: -8 < y < -3

Hence, the range of the function is -8 < y < -3

For a college chemistry experiment, students need to prepare a solution containing ethylene glycol. They are each given 20 fluid ounces of a solution containing 2% ethylene glycol, to which they will add another solution that contains 12% ethylene glycol. How much of the 12% solution should they add to obtain a 5% ethylene glycol solution?

Answers

Students should add 8.6 fluid ounces of 12% ethylene glycol.

Using the relation between concentration and volume of solution to find the required amount of 12% ethylene glycol to be used. Let the required amount of 12% ethylene glycol be x fluid ounces. Forming the relation as follows -

C₁ × V₁ + C₂ × V₂ = C₃ × V₃

C₁ and V₁ represents 2% ethylene glycol, C₂ and V₂ represents 12% ethylene glycol and C₃ and V₃ represents 5% ethylene glycol solution. As V₂ is x, so, V₃ will be (20 + x).

Keep the values in formula to find the value of x

2%×20 + 12%×x = 5%×(20 + x)

Solving the equation for the value of x

2/100×20 + 12/100×x = 5/100×20 + 5/100×x

0.4 + 0.12x = 1 + 0.05x

Rearrange the equation -

0.12x - 0.05x = 1 - 0.4

Performing subtraction on both sides -

0.07x = 0.6

Shifting 0.07 to Right Hand Side and performing division

x = 0.6 ÷ 0.07

x = 8.6 fluid ounces

Hence, 8.6 fluid ounces of the 12% ethylene glycol should be added.

Triangle ABC lies on the coordinate plane with the vertices A(7,6), B(-3,5) and C(-6,1).

The triangle is transformed using the rule (x, y) --> (x+4, 3y) to create triangle A'B'C'.

What are the coordinates of B'?

Answers

Check out the attached photo

The transformation, the coordinates of point B' become (1, 15).

The transformation rule (x, y) → (x + 4, 3y) involves shifting the x-coordinate by 4 units to the right and stretching the y-coordinate by a factor of 3. To find the coordinates of B' after applying this rule, we take the coordinates of point B(-3, 5):

x-coordinate of B' = x-coordinate of B + 4 = -3 + 4 = 1.

y-coordinate of B' = y-coordinate of B * 3 = 5 * 3 = 15.

Therefore, after the transformation, the coordinates of point B' become (1, 15). This means that B' is located 4 units to the right of B along the x-axis and its y-coordinate is three times that of B. The transformation has shifted and stretched the original triangle, resulting in a new position for point B'.

Put the following equation of a line into slope-intercept form, simplifying all fractions.
20x+4y=8

Answers

the answer for the given question is slope is -5 and y- intercept is 2.

The slope intercept form of a straight line is one of the most common ways to represent a line's equation. When given the slope of a straight line and the y-intercept, the slope intercept formula can be used to find the equation of a line (the y-coordinate of the point where the line intersects the y-axis).

The slope-intercept form is y = mx + b , where m is the slope and b is the y-intercept.

y = mx + b

Take 20x off both sides of the equation.

4y = 8 − 20x

Simplify each term by dividing it by 4y = 8 - 20x.

y = 2 − 5x

Reorder 2 and -5x.

y =−5x + 2

Therefore after simplification we get the slope as -5

and the y-intercept as 2

How to Interpret Graph Intervals?

The information that we have is:

"The graph of y = -1/2x + 2 is  is negative over the interval (4, ∞) and positive over the interval (-∞, 4)."

Now, if for values of x smaller than 4 the graph is negative and for values of x larger than 4 the graph is positive, this must be that the graph must crosses the x-axis at some point, then with only that information, we can conclude that the graph is equal to zero when x = 4.
