please help me with number 5 it’s been due

Answer:

C. 9d=m

Step-by-step explanation:

Answer:

Step-by-step explanation:

If the numbers after the decimal terminate, yes, it's rational.

9.521521521 = 9,521,521,521 / 1,000,000,000

If they don't terminate, but the pattern continues (which I suspect is the case here), yes, it's still rational.

If x = 9.521521521…, then

1000x = 9521.521521521…

Subtract x from this to eliminate the fractional part:

1000x - x = 9521.521521521… - 9.521521521…

999x = 9512

x = 9512/999

If they don't terminate, but the pattern does not continue, meaning the next few digits could be something random like

9.52152152119484929271283583457…

then the number would be irrational.

Lin is correct.

An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable, is called its function.

Given that, Lin says that a snack machine is like a function because it outputs an item for each code input.

Lin is correct because, function tells the relation between an output to its input.

A function is a relation from the set of the inputs to a set of all possible outputs, where each input is related to exactly one output.

So Lin's opinion about snack machine is correct as the snack machine is output an item for each code input.

Answer:

The third angle would measure 80 degrees

Step-by-step explanation

The equal measure of each angle in a triangle adds up to 180 degrees. The first two angles of 70 and 30 equal 100. Thus, the third angle will measure out to be 80 degrees. Have a great day!

Answer:

After 1 month, they will have same heights.

Step-by-step explanation:

Calvin is comparing the growth of two plants.

Plant A started at a height of four inches and grows two inches each month.

h'=4+2m

where

h' is height of plant after m months.

Plant B grew according to this equation, h = 4m + 2, where h, is the height after m, months.

We need to find at what month the plants have the same height. ATQ.

h = h'

4+2m = 4m + 2

Taking like terms together,

4-2 = 4m-2m

2=2m

m = 1

Hence, after 1 month, the plants will have same height.

Answer: the answer to this is  9 miles an hour

Step-by-step explanation: 1. What this is asking is to make the fraction a bit easier to understand. So all we do is divide the numerator by the denominator. You can use this method for any other math problems like this also.  

2.  All this chart is doing is multiply the input or output by 9. If you look you can see the hours is multiplied by nine. I hope this helped.

Answer:

The equation of the line is y = 3x - 1 ⇒ b

Step-by-step explanation:

From the given graph

∵ The rule of the slope of the line is m = [tex]\frac{y2-y1}{x2-x1}[/tex]

∵ (x1, y1) and (x2, y2) are two points on the line

∵ The line passes through points (0, -1) and (1, 2)

∴ x1 = 0 and y1 = -1

∴ x2 = 1 and y2 = 2

→ Substitute them in the rule of the slope to find it.

∵ m = [tex]\frac{2--1}{1-0}[/tex] = [tex]\frac{2+1}{1}[/tex] = [tex]\frac{3}{1}[/tex]

∴ m = 3

∵ The line intersects the y-axis at point (0, -1)

∴ The y-intercept = -1

∵ The form of the equation of the line is y = m x + b

∵ b is the y-intercept

∴ b = -1

→ Substitute the values of m and b in the form of the equation

∵ y = 3x + -1

∴ y = 3x - 1

∴ The equation of the line is y = 3x - 1

Answer: She had left 54% of the money which is $1620.

Step-by-step explanation:

40% of $3000 = $1200

15% of $1200 = $180

$3000 - ($1200 + $180)

$3000 - $1380 = $1620

$1620 is the money she had left.

$1620 is 54% of $3000

She had 54% left of the money.

Answer:

Zero

Step-by-step explanation:

The graph depicts a horizontal line.

All horizontal lines have no slope. If you pick two points from the line and use the slope formula, the numerator would be zero.

Zero divided by any number is zero.

Work Shown

45 girls : 15 boys

45/15 girls : 15/15 boys .... divide both parts by 15

3 girls : 1 boy

This tells us there are three times as many girls as there are boys.

We write this as the ratio 3 : 1. The order of the terms is important. We cannot say 1:3 since that would imply there are more boys than girls, but it's the other way around.
