Final answer:

The question lacks specific details, making it impossible to provide a structured and detailed response designed to meet the student's needs.

Explanation:

As the student question has not provided specific details or context about the topic they're struggling with, it's impossible to provide a clear, factual, and step-by-step explanation targetted to their needs. It is highly recommended that the student provides more details about the subject or the exact problem they are encountering in their grade 9 course to receive a structured and effective response. To help you understand better, could you please provide the specific question or topic you need assistance with? That way, I can provide a step-by-step explanation and relevant examples to help you.

Making Consumer ChoicesI. The Bread Machine (25 points)r /> In real life, you must often make choices about whether to buy something pre-made or make it yourself. There are many things to consider: quality of homemade vs. bought, expense, convenience, enjoyment of making something, etc. In this response, you will be looking at the choice of buying a bread machine or relying exclusively on store bought bread.

A. The bread machine you are interested in costs $100 with tax.
The ingredients to make one loaf of bread cost $0.80.
What is the rate of cost of one loaf of bread?

B. What is your start up cost? (cost of machine)

C. Write a linear equation, y = mx + b for the total cost.

D. Graph the equation on the graph provided. You may use either Point Plotting or Slope-Intercept. Be sure to locate at least 3 points. You may want to do this in pencil in case you decide to use more points later in the problem.

Answers

cool question relying on real life scinarios

A.

1 loaf=inital cost for macine+cost per bread or
number of loaves=x
cost to make=y
y=100+0.8x
so to find 1 loaf, just subsitute 1 for x
y=100+.8(1)
y=100+0.8
y=100.80
1 loaf costs $100.80 to make

B.
start up cost is $100

C. linear equation is
start up cost+cost per loaf times loaf or
y=100+0.8x
in y=mx+b form
y=0.8x+100

C.
to find points, just subsitute values for x and get values for y (I used multiplules of 10 so that you wouldn't have to plot a decimal coordinate)

if we put it 0 for x, we get 100 for y
if we put in 10 for x, we get 108 for y
if we put in 20 for x, we get 116 for y
and of course don't use negative becasue you can't make negative amounts of bread

I am a little confused: One method you can use to determine whether a triangle is a right triangle, given three side lengths, is to apply the converse of the Pythagorean Theorem. Alternately, you can use trigonometric ratios. Show that the triangle in the diagram is a right triangle by using trigonometric ratios. ( Be sure to show all work/and or reasoning.

Answers

Answer with explanation:

The triangle in the Diagram Described has following measurement:

Longest Side = 65 units

One side which can be either Perpendicular or base = 63 units

And , other side which can be also, either Perpendicular or base = 16 units

We can prove that the triangle described is right triangle by two ways.

1. Using Converse of Pythagorean Theorem

Square of Longest side = Sum of Squares of other two sides-----(1)

So, Square of Longest Side = 65²=4225

Sum of Square of other two sides = 16² + 63²

= 256 + 3969

= 4225

Statement (1), is valid.

So,Triangle is right angled triangle, right angled at A.

2. using Trigonometric Ratios

Suppose the triangle is right Angled at A.

In Right triangle B AC

$tan B=\frac{\text{Perpendicular}}{\text{Base}}\n\ntan B=(16)/(63)\n\ntan C=(63)/(16)\n\n tan(B +C)=(tan B + tan C)/(1-tan B * tanC)\n\ntan (B +C)=((16)/(63)+(63)/(16))/(1-(16)/(63)* (63)/(16))\n\ntan (B +C)=\frac{\text{Any rational number}}{0}\n\ntan (B +C)=\infty\n\nB +C=90^(\circ)\n\n \text{Using the trigonometric Identity},tan(A+B)=(tan A +tan B)/(1-tan A*tan B)$

B +C =90°

Also,→ ∠A + ∠B + ∠C=180°≡ (Angle sum property of triangle)

→∠A +90°=180°

→∠A=180° -90°

→∠A=90°

So, triangle is right Angled triangle , Right angled at A.

Hence ,proved.

Trigonometric ratios are sine, cosine, and tangent (opposite side over hypotenuse, adjacent side over hypotenuse, and opposite side over adjacent side, respectively); if you wanted to prove that one of the angles of the triangle is 90º, then the cosine of that angle would be 0, the sine would be 1, and the tangent would be undefined.

Answer:

{0}

Step-by-step explanation:

|n/6| + 1 = 1

Subtract 1 from each side

|n/6| + 1-1 = 1-1

|n/6| =0

Since this is equal to zero what is inside the absolute value must equal zero

n/6 =0

n =0

Answer:

B) {0}

Step-by-step explanation:

Let's go step by step

|n/6| + 1 = 1

First step is to subtract 1 from both sides:

|n/6| = 0

Now, we can multiply both sides by 6:

n = 0

783 rounded to the nearest hundred is

Answers

Answer:

Rounded to the nearest hundred is 790.

Step-by-step explanation:

Given : Number 783.

To find : Number rounded to the nearest hundred ?

Solution :

Nearest hundred means,

When the digit at tens place is greater than or equal to 5 then the number round by 1 and rest became zero.

When the tens digit place is less than 5 then the number remain same and rest became zero.

Number 783.

Tens place is 8 >5 so it round by adding 1,

$783\approx 790$

Therefore, Rounded to the nearest hundred is 790.

783 rounded to the nearest hundred is 800

To round 783 to the nearest hundred,

Since we know that,

A mathematical process known as "round off nearest hundred" involves rounding a number to the nearest hundred. The final two digits of the number will be examined, and we will round them to the closest hundred.

Look at the digit in the tens place, which is an 8.

Because 8 is greater than or equal to 5,

Round up to the nearest hundred.

To do this, we add 1 to the digit in the hundreds place, which is 7,

and change the digits in the tens and ones places to 0.

So, 783 rounded to the nearest hundred is 800.
