answer question bellow!!!
Ms. Dangerfield wants to order 980 erasers for her class for the whole school year. Amazon is selling a bag of 250 erasers for a great price! How many bags of erasers should Ms.Dangerfield buy to have enough for her class this school year? You can use a number line to help you solve.
Answer:
4 packages
Step-by-step explanation:
We have to do 980/250.
So after you get that, you would get 3.92. It would not make sense to get 3.92 packages since that isn't possible on Amazon using common sense. Therefore we must round 3.92 to 4 packages.
Answer:
Ms.Dangerfeild should order 4 bags
Step-by-step explanation:
250 times 4 is 1000 so Ms.Dangerfeild will have 20 extra erasers.
. The equation = can be used to find how many hours h a person needs to work to earn $200 at $8 per hour. How many hours does a person need to work to earn $200?
Answer:
0.04 h
Step-by-step explanation:
The given equation is :
8h=200
It is used to find hours h a person needs to work to earn $200 at $8 per hour.
We need to find no of hours does a person need to work to earn $200. It can be calculated as follows :
[tex]\dfrac{8h}{200}=\dfrac{200}{200}\\\\h = 0.04\ h[/tex]
So, for $200, the person will need 0.04 h.

Give an example of how you use positive and negative numbers, and explain the meaning of 0 in your example.
please help me
Answer:
Meanings of the numbers:
Most numbers represent an amount. Positive numbers represent above zero. Zero is the only number that does not represent an amount. It means nothing. When you go lower than nothing, you are in the negative numbers. Negative numbers represent absent values pretty much.
How I would use them in every day life:
I would use positive numbers to represent... maybe something I'm trying to get at a store. Ex: 4 bananas
I would use negative numbers to... maybe look at the temperature. Ex: -16 degrees Fahrenheit. Negative numbers are in temperature all the time.

Which equation represents a line that has a slope of 3/4 and passes through the point (2;1)?
A;3y = 4x - 5
B;4y=3x - 2
C4y= 3x+5
Answer:
B
Step-by-step explanation:
m = 3/4
x1 = 2
y1 = 1
Using the formula,
y - y1 = m(x - x1)
y - 1 = 3/4(x - 2)
y - 1 = 3x/4 - 3/2
y = 3x/4 -3/2 + 1
y = 3x/4 - 1/2 (×4)
4y = 3x - 2
Therefore, the answer is B
The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
The equation of the line that passes through (2, 1) and 3/4 as its slope.
4y = 3x - 2
Option B is the correct answer.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
Slope = 3/4
m = 3/4
The point that passes through = (2, 1)
Now,
The equation of the line is y = mx + c.
y = (3/4)x + c
We will take (2, 1) = (x, y) since it passes through the line.
1 = (3/4)2 + c
1 = 3/2 + c
c = 1 - 3/2
c = -1/2
Now,
The equation of the line that passes through (2, 1) and 3/4 as its slope.
y = (3/4)x -1/2
y = (3x - 2)/4
4y = 3x - 2
Thus,
The equation of the line that passes through (2, 1) and 3/4 as its slope.
4y = 3x - 2
Option B is the correct answer.

Determine the value of angle ECB
Please help me out!
Answer: ∠ECB = 60°
Step-by-step explanation:
First, find the value of x by adding them up.
x + 3x + 2x = 6x
Since we know that all of the angles create a 180° angle, we can set up a proportion.
6x = 180°
To find the value of x, divide both sides by 6.
6x ÷ 6 = x
180 ÷ 6 = 30
So now the proportion is x = 30.
Now that we now x = 30, we can plug in 30 to the angle measures.
∠DCA = 30°
∠DCE = 90°
∠ECB = 60°
So angle ECB is 60°.

2 The value of y is directly proportional
to the value of x.
If y = 35 when x = 140, what is the
value of y when x=70
Answer:
y = 17.5
Step-by-step explanation:
Given that y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition y = 35 when x = 140, then
35 = 140k ( divide both sides by 140 )
0.25 = k
y = 0.25x ← equation of proportion
When x = 70, then
y = 0.25 × 70 = 17.5
What is x in this question ax=12
if there no other info given to you then I guess the answer would be x = 2 since (a) would equal 6?
9514 1404 393
Answer:
x = 12/a
Step-by-step explanation:
To find the value of x, divide both sides of the equation by its coefficient.
ax = 12
(ax)/a = 12/a
x = 12/a

What is the solution to the equation 3x + 2(x - 9) = 8x + x - 14?
A.-8
B.-1
C.1
D.8
Answer:
B.) -1
Step-by-step explanation:
Here, 3x + 2(x - 9) = 8x + x - 14 is given
Now, we will solve and we get,
3x + 2(x - 9) = 8x + x - 14
3x + 2x - 18 = 9x - 14
5x - 9x = 18 - 14
-4x = 4
4x = -4
x = -4÷4
x = -1
Thus, The value of x is -1
Hence, Option B is correct

Researchers randomly choose two groups from 15 volunteers. Over a period of 9 weeks, one group watches television before going to sleep, and the other does not. Volunteers wear monitoring devices while sleeping, and researchers record dream activity. Which type of study method is described in each situation? Group of answer choices a) observational study b) controlled experiment c) survey
Answer: B. Controlled experiment
Step-by-step explanation:
This is a controlled experiment because the variables in the question are manipulated by the researcher. We are told that while one group watches television before going to sleep, the other group does not.
The controllers won't have control over the variables that were used if it was an observational study while for a survey, it has to do with collection of information regarding certain topics or happenings in order to have people's perception on the topic or area of interest.

If 8 containers of cold brew coffee cost $24.80, what is the constant of proportionality?
Answer:
3.1
Step-by-step explanation:
The sum of two angles is 180 degrees. Their difference is 70
degrees.
What is the measure of the smaller angle?
Step-by-step explanation:
x+y=180
x=180-y------(i)
x-y=70------(ii)
Now,
Putting the value of x in equation (ii)
x-y=70
(180-y)-y=70
180+2y=70
2y=70-180
2y= - 110
y= - 110/2
y= - 55
Again,
x=180-(-55)
x=235
x-y=70
x-(-55)=70
x+55=70
x=70-55
x=15
