Why or Why not? Explain how you know using math language and your knowledge of means/averages.

Answers

Answer 1

Answer:

yes i think

Step-by-step explanation

because Mr. R has many better percentages than Mr. D.

for example, Mr. D., you would expect, has less better grades from his class than Mr. R.

but i think they want to confuse you so Mr Robin is greater

then again this is a guess off my knowledge

Answer:

x = 20

Step-by-step explanation:

The triangle shown is an equilateral triangle.  An equilateral triangle has angles that are all the same.  Therefore, the expression 4x-20 equals the value of the angle, which is 60 degrees.  To find x, you just have to do some simple algebra.

4x - 20 = 60 ..... set the expression equal to 60, that's what the angle equals

4x = 80 .... add 20 to both sides

x = 20 .... divide both sides by 4, and you get your answer

What is fraction?

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.

Given:

Ryan takes = 7/10 hour to get ready.

Ryan takes 1/4 hour to travel.

So, the total time he taken

= 7/10 + 1/4

= 7/10 x 2/2 + 1/4 x 5/5

= 14/20 + 5/20

=19/20

Hence, it takes 19/20 hour.

Step-by-step explanation: The fashion express magazine having 4,880 subscribers and losing 300 times something lines up with that in the expression. And the new trends magazine having 3,140 and gaining 280 times something lines up with the expression. The expression is also suppose to be equal and the word problem is asking for when the subscriber count would be equal. Solving the expression using the word problem would have you end up with m = 3, so in 3 months they will have equal subscribers (aka both will have 3,980 subscribers)

help me pls it’s due today thanks!

Answers

i believe the answer would be C

Answer:

C

Step-by-step explanation:

Monthly salary is $1,750 plus commission for every car he sells.

If he sells 1 car, then his monthly income is $2,250

This means his commission for every car sold is 2250 - 1750 = $500

Thus M = 500n + 1,750

To confirm lets substitute 5 as n.

M = (500 x 5) + 1750

M = 2500 + 1750

M = $4,250

This matches the answer found in the table.

Find the slope to the graph

Answers

Answer:

the slope is 3/2

Step-by-step explanation:

Answer:

[tex]\frac32[/tex]

Step-by-step explanation:

Hello!

We can solve for the slope using the formula [tex]\frac{Rise}{Run}[/tex].

Rise is the change in y between two pointsRun is the change in x between two points

We need two points that belong on this line to find the slope. The two points I'm picking are (-1,-1) and (1,2).

Calculate the SlopeThe change in y (-1 and 2) is 3The change in x (-1 and 1) is 2

Plugging it into the formula, we get a slope of  [tex]\frac32[/tex].

Perpendicular, parallel, or neither?

Answers

Answer:

The two lines are parallel

Step-by-step explanation:

Parallel lines have equal slopes and different y-interceptsThe product of the slopes of the perpendicular lines is -1 which means if the slope of one is m, then the slope of the other is [tex]-\frac{1}{m}[/tex] (reciprocal m and change its sign)The slope of the equation ax + by = c is m = [tex]\frac{-a}{b}[/tex]The slope of the equation by = ax + c is m = [tex]\frac{a}{b}[/tex]

Let us use these rules to solve the question

∵ The 1st equation is -4y = -2x + b

a = -2 and b = -4

∵ m = [tex]\frac{a}{b}[/tex] in this form of the equation

∴ m = [tex]\frac{-2}{-4}[/tex]

m1 = [tex]\frac{1}{2}[/tex]

∵ The 2nd equation is 3x - 6y = 6

a = 3 and b = -6

∵ m = [tex]\frac{-a}{b}[/tex] in this form of the equation

∴ m = [tex]\frac{-3}{-6}[/tex]

m2 = [tex]\frac{1}{2}[/tex]

m1 = m2

∴ The slopes of the two lines are equal

→ That means the two lines are parallel

The two lines are parallel

Which is greater 3.75 3.750

Answers

Answer:

None

Step-by-step explanation:

They are the same number

They are equal and neither is greater than the other.

In the decimal number system, trailing zeros after the decimal point do not affect the value of the number. They are considered insignificant and are not used to determine the magnitude or comparison of the numbers.

When comparing 3.75 and 3.750, it's important to understand that they represent the same value. The digits after the decimal point in both numbers are identical. The presence of the trailing zeros in 3.750 does not change the actual value of the number; it's just a different representation.

To illustrate this, let's consider the number line:

3.749  <  3.7499  <  3.74999  <  3.75  =  3.750  <  3.7501  <  3.75001  <  3.751

As you can see, both 3.75 and 3.750 lie at the same point on the number line, indicating that they are equal in value. The trailing zeros in 3.750 are insignificant and do not affect the magnitude or comparison of the numbers.

Therefore, in terms of their numerical value, 3.75 and 3.750 are equivalent and not different from each other.
