A square sticky note has sides that are 15 centimeters long. What is the area of the sticky note?

There are 48 green ribbons

Given that the ratio of red ribbons to green ribbons is 4 to 6

Which can be written in following way:-

[tex]\frac{\text {Red} r i b b o n}{\text {Green ribbon}}=\frac{4}{6}[/tex]

There are total number of 32 red ribbons

We have to determine the number of green ribbon

Let the number of green ribbon be ‘6a’

And number of red ribbons be "4a"

Given number of red ribbons = 32

4a = 32

a = 8

number of green ribbon = 6a = 6(8) = 48

Therefore number of green ribbons is 48

Final answer:

To find the number of green ribbons, the ratio of red to green is scaled to match the actual count of red ribbons. With 32 red ribbons and a ratio of 4:6, there are 48 green ribbons.

Explanation:

To solve the problem, we need to find out how many green ribbons there are when we know that the ratio of red ribbons to green ribbons is 4 to 6 and there are 32 red ribbons in total.

First, let's use the given ratio. Ratios can be scaled up by the same factor on both sides to represent actual quantities. So, if we have 4x red ribbons and 6x green ribbons, and we know 4x = 32, we can solve for x: x = 32 / 4 = 8. This means for every 8 red ribbons, there are 12 green ribbons since 6x = 6 × 8 = 48.

Therefore, if there are 32 red ribbons, there are (32 / 8) × 12 = 4 × 12 = 48 green ribbons.

Answer:

a) Mr. Sanchez's class sold 28 fruit pies and Mr. Kelly's class sold 32 bottles of fruit juice.

b) Mr. Kelly's class

c) Mr. Kelly's classs earned  $1.40 more than Mr. Sanchez's class.

Step-by-step explanation:

Let x be the number of fruit pies sold and y be the number of bottles of fruit juice sold.

Together, the classes sold 60 items, so

x + y = 60

Mr. Sanchez’s class sold fruit pies for $1.55 each, so x fruit pies cost $1.55x.

Mr. Kelly’s class sold bottles of fruit juice for $1.40 each, so y bottles of fruit juice cost $1.40y.

Together, the classes  earned $88.20 for their school, so

1.55x + 1.40y = 88.20.

a) You get the system of two equations:

[tex]\left\{\begin{array}{l}x+y=60\\ \\1.55x+1.40y=88.20\end{array}\right.[/tex]

From the first equation:

[tex]x=60-y[/tex]

Substitute it into the second equation:

[tex]1.55(60-y)+1.4y=88.2\\ \\155(60-y)+140y=8,820\\ \\9,300-155y+140y=8,820\\ \\-15y=8,820-9,300\\ \\-15y=-480\\ \\15y=480\\ \\y=32\\ \\x=60-32=28[/tex]

Mr. Sanchez's class sold 28 fruit pies and Mr. Kelly's class sold 32 bottles of fruit juice.

b) Mr. Sanchez's calss earned:

[tex]\$1.55\cdot 28=\$43.40[/tex]

Mr. Kellyz's calss earned:

[tex]\$1.40\cdot 32=\$44.80[/tex]

Since [tex]\$44.80>\$43.40,[/tex] Mr. Kelly's class earned more.

c) Mr. Kelly's classs earned  [tex]\$44.80-\$43.40=\$1.40[/tex] more than Mr. Sanchez's class.

Jason hit 11 homeruns.

Step-by-step explanation:

Homeruns hit by Nathan = 19

Let,

Homeruns hit by Nathan = x

Homerun hit by Jason = y

According to given statement;

x = 2y - 3   Eqn 1

We know that Nathan hit 19 homeruns, therefore, putting x=19 in Eqn 1

[tex]19=2y-3\\19+3=2y\\22=2y\\2y=22[/tex]

Dividing both sides by 2;

[tex]\frac{2y}{2}=\frac{22}{2}\\y=11[/tex]

Jason hit 11 homeruns.

The lines are:  B) Perpendicular

Step-by-step explanation:

we have to convert both lines in slope-intercept form to find slopes

So,

[tex]3x - 6y = -13\\-6y = -3x-13\\\frac{-6y}{-6} = \frac{-3x-13}{-6}\\\frac{-6y}{-6} = \frac{-3x}{-6}+\frac{-13}{-6}\\y = \frac{1}{2} +\frac{13}{6}[/tex]

Let m1 be the slope of first line

[tex]m_1 = \frac{1}{2}[/tex]

For the second line:

[tex]18x + 9y = 5\\9y = -18x+5\\\frac{9y}{9} = \frac{-18x+5}{9}\\\frac{9y}{9} = \frac{-18}{9}x+\frac{5}{9}\\y = -2x+\frac{5}{9}[/tex]

Let m2 be the slope of line 2

So,

If the lines are parallel, their slopes are equal

If the lines are perpendicular, product of their slopes is -1

We can see that

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

Hence,

The lines are:  B) Perpendicular

The lines given by the equations 3x - 6y = -13 and 18x + 9y = 5 are neither parallel nor perpendicular because their slopes, 1/2 and -2 respectively, are neither equal nor negative reciprocals of each other.

To decide whether the pair of lines given by the equations 3x - 6y = -13 and 18x + 9y = 5 is parallel, perpendicular, or neither, we need to find the slope of each line. First, we convert the equations into the slope-intercept form, which is y = mx + b where m is the slope.

For the first equation, 3x - 6y = -13, we solve for y:

The slope of this line is 1/2.

For the second equation, 18x + 9y = 5, we also solve for y:

The slope of this line is -2.

Since the slopes of the two lines are neither equal (which would make them parallel) nor negative reciprocals of each other (which would make them perpendicular), the lines are neither parallel nor perpendicular.

Answer:

E=5

Step-by-step explanation:

Given,

[tex]32= 2^E[/tex]

We know [tex]32[/tex] can be written as [tex]2^5[/tex]

Substituting [tex]2^5[/tex] in place of [tex]32[/tex]

We get,

[tex]2^5 = 2^E[/tex]

Since the base is equal, now comparing the exponent.

Therefore [tex]E=5[/tex] is the missing exponent.

Answer:

E = 5 and [tex]32 = 2^5[/tex]

Step-by-step explanation:

Given:

[tex]32 = 2^E[/tex]

Now we know that E is denoted as an exponent term,

Exponent term indicates the value which can be to the power of a number.

Now 32 can be written as,

[tex]32 = 2\times 2\times2\times 2\times2[/tex]

Hence from above we can say that 2 can be multiplied 5 times to get the value as 32.

hence we can say that,

[tex]32 = 2^5[/tex]

Hence E=5

Rewriting the expression 15x+9 as 9+ 15x is an example of the commutative property of addition

The commutative property of addition states that when two numbers are being added, their order can be changed without affecting the sum.

To “commute” means to move around or travel.  

According to the commutative property of addition, changing the order of the numbers we are adding, does not change the sum

When two numbers are added, the sum is the same regardless of the order of the addends. For example 4 + 2 = 2 + 4

For addition, the rule is a + b = b + a

Here in the problem 15x + 9 is equivalent to 9 + 15x

Hence, rewriting the expression 15x+9 as 9+ 15x is an example of the commutative property of addition

The process of rewriting 15x + 9 as 9 + 15x uses the Commutative property of addition. This asserts that changing the order of addition doesn't affect the sum.

Rewriting the expression 15x+9 as 9+15x is an example of the Commutative property of addition. The Commutative property states that the order in which you add or multiply numbers does not affect the sum or product. So in your case, 15x + 9 =  9 + 15x because of the Commutative property of addition. This is true for addition of ordinary numbers as well, for instance 2 + 3 will yield the same result as 3 + 2.

Distance = |b - c|

Step-by-step explanation:

Suppose a, b, and c are all negative numbers.

We have to describe the way to find the distance between points (a,b) and (a.c).

Since the x-coordinates of the two points are the same and are a, therefore, the distance between the y-coordinates of the two points will give the distance between the two points.

Mathematically the distance d will be given by d = |b - c|, where |x| is the absolute value function of x. (Answer)

I don't really understand the question, but this is what I think it is

Eric needs to have $60 in savings if he wants to spend only 40% of it on a $24 video game.

To determine how much Eric must have in savings to spend only 40% on a $24 video game, we set up a simple equation where 40% of his total savings (S) equals the price of the game ($24). The equation is 0.40 × S = $24. Solving this equation for S (total savings), we divide both sides by 0.40:

× S = $24
÷ 0.40 ÷ 0.40

S = $24 ÷ 0.40
S = $60

Therefore, Eric must have a total of $60 in savings to spend only 40% on the video game.

Answer:

The value of x = 13.5.

Step-by-step explanation:

In this question x is missing.

So, the question would be:

tan 34° = x/20.

Now, to find the value of [tex]x[/tex]:

[tex]tan 34 = \frac{x}{20}[/tex]

[tex]\frac{x}{20} = tan 34[/tex]

Multiplying both sides by 20 we get:

[tex]x=tan 34\times 20[/tex]

On simplifying both sides we get:

[tex]x=13.49[/tex]

So, to get the value of [tex]x=13.49[/tex] to nearest tenth is 13.5. As we see in hundredth place it is 9 and 4 in tenth place, so after rounding to tenth place 4 will change to 5 so the value is 13.5.

Therefore, the value of x = 13.5.
