Kato must write 60 percent of a 20-page report by tomorrow. Kato wants to determine the number of pages that he needs to write by tomorrow. Kato’s work is shown below.

Step 1: Write 60 percent as a ratio. part/whole = 60/100
Step 2: Write an equivalent ratio that has the answer in the numerator and 20 in the denominator.
Step 3: 100 divided by 20 = 5
Step 4: 60(5) = 180

What mistake did Kato make?
In Step 1, Kato should have written the ratio as 100/60.
In Step 2, Kato should have put 20 in the numerator.
In Step 3, Kato should have multiplied 100 by 5.
In Step 4, Kato should have divided 60 by 5.

When evaluating (8x+9)? -5 for x = 1, the given value of 1 is substituted for what part of the expression?

A.the exponent

B. The constant

C. the variable

D.any numerical value

Answers

Answer:

C. The variable

Step-by-step explanation:

The given value states that all values of x will be replaced by 1. The definition of a variable in algebra is a symbol for a number we don't know yet, so x will be the variable in this equation

Answer:

C. the variable

Step-by-step explanation:

(8x+9) -5 <----- The original question.

(8(1)+9) -5 <----- Replacing the variable.

(8 + 9) -5  <------ Completing the multiplication.

17 - 5  =     <----- Doing the addition.

Find the distance between the x-intercept and the y-intercept of the graph of the equation 5x - 12y = 60.

Answers

Answer:

[tex]d = 13[/tex]

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Algebra I

Slope-Intercept Form: y = mx + b

m - slope b - y-intercept

The y-intercept is the y value when x = 0.  Another way to reword that is when the graph crosses the y-axis.

The x-intercept is the x value when y = 0.  Another way to reword that is when the graph crosses the x-axis.

Algebra II

Distance Formula: [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Step-by-step explanation:

Step 1: Define

Equation 5x - 12y = 60

Step 2: Rewrite in slope-intercept form

Isolate y term:                   -12y = 60 - 5xIsolate y:                            y = -5 + 5/12xRewrite:                             y = 5/12x - 5

Step 3: Find x and y intercept

x-intercept

Set y = 0:                    0 = 5/12x - 5Isolate x term:            5 = 5/12xIsolate x:                     12 = xRewrite:                      x = 12

y-intercept

Define:                    y = 5/12x - 5Break:                     y = -5

Step 4: Write coordinates

x-int (12, 0)

y-int (0, -5)

Step 5: Find distance d

Substitute:                    [tex]d = \sqrt{(0-12)^2+(-5-0)^2}[/tex]Subtract:                       [tex]d = \sqrt{(-12)^2+(-5)^2}[/tex]Evaluate:                       [tex]d = \sqrt{144+25}[/tex]Add:                              [tex]d = \sqrt{169}[/tex]Evaluate:                      [tex]d = 13[/tex]

So I've been not doing my homework and stuff. I have been talking to online people, which I shouldn't have been. They found out and stuff. My parents are putting me in pubic school. They said I can finish the first semester but I'm not doing the second. I have finished 4 of my classes and finishing up the other two. I really don't want to go to pubic school.
My question is.
How do I focus on my homework and convince my parents to let me stay in online school?
My grades are at an A and rest are B's. I want to show them that I can stay in the second semester and do my homework. PLEASE HELP ME OUT

Answers

Hello, I know your situation. Ask them for another chance. Ask them to forgive you and you will do your homework. Say "If this continues, then I accept full consiquinses". Make sure you ACTUALLY stick to what you say. Now, to the focusing part... Try to do ATLEAST 2 lessons for each class. (depends what school you are attending) If it seems that you are finishing too fast (less than 2 hrs), then do more homework until your homework hours fits you.

Goodluck!

God Bless you!!!

i think the best thing you could do is just stay away from distractions and show them that you been doing fine with online classes...

or just tell them that a bunch of people at school are coughing or showing symptoms and that they might have c****

A food company produced 65 pounds of a new cereal and was going to package it in 4-ounce boxes. The cardboard company is offering a special price on 5-ounce boxes. Will the food company have more or fewer promotional boxes if they decide to go with the 5-ounce boxes instead of the 4-ounce boxes?

Answers

Answer:

Fewer boxes

Step-by-step explanation:

There are 16 oz in a pound

So 65 bs = 65  x 4 = 1040 ounces

If packaged in 4-ounce boxes, number of boxes = 1040 /4 = 260  boxes

If packaged in 5-ounce boxes, number of boxes = 1040/5 = 208 boxes
