Answer:
Step-by-step explanation:
Given the equation y = 2,5x
y is the height of the water
x is the time.
To get the range of values of the height at t = 60s, we will substitute x = 60 into the function
y = 2.5(60)
y = 150 in
Hence the range of the situation is [0, 150].
The domain will be all positive integers i.e xEZ

Respect to time as a line. What is the slope of line?
Please help !
Answer:
it is C
Step-by-step explanation:
i took all the test and got a hundred
if we graph his distance with respect to time as a line then slope of line is 45.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Arturo after 3 hours of driving is 135 miles from home. After 5 hours of driving, he is 225 miles
from home
Let the two points are (3, 135) and (5,225)
m=225-135/5-3
=90/2
=45
Hence, if we graph his distance with respect to time as a line then slope of line is 45.

Select the equation of the line parallel to y=-4x-6 the
equation and that passes through the point (1, 2).
O y=-4x+6
O y=4x-4
O y=-4x-4
O y = 4x+6
Answer:
[tex]y=-4x+6[/tex]
Step-by-step explanation:
If you are looking for a parallel line with just the equation then look for an equation with the same slope and different Y intercept. After you find that just check and see if it passes the coordinate.
[tex]2=-4(1)+6[/tex]
[tex]2=-4+6[/tex]
[tex]2=2[/tex]
If it works you have your answer!
The equation of the line parallel to y = -4x - 6 and passing through (1, 2) is
y = -4x + 6.
The slope of y = -4x - 6 is -4.
passing through the point (1, 2)
the new line is parallel to the original line, it will have the same slope (-4).
Use the point-slope form of a linear equation to write the equation of the new line. The point-slope form is y - y1 = m(x - x1), where m is the slope, and (x1, y1) is the given point.
substituting values,
y - 2 = -4(x - 1)
y - 2 = -4x + 4
y = -4x + 6

Solve the following equation for p. What POSITIVE value of p? 10 - 43 - |7p + 12|
Answer:
Subtract
43
from
10
.
−
33
−
|
7
p
+
12
|
Step-by-step explanation:
The positive value of p from the equation is; p = 3
This is about absolute values.
We are given the equation;10 = 43 - |7p + 12|
Let us simplify by subtracting 43 from both sides to leave the right hand side as an absolute value form.10 - 43 = - |7p + 12|
-33 = - |7p + 12|
divide both sides by -1 to get;
33 = |7p + 12|

Determine the slope of the line that passes through the points M(-3, 5) and N(1, 8). Represent the slope in decimal form.
Answer:
The slope of the line that passes through the points M(-3, 5) and N(1, 8) in decimal form is 0.75
Step-by-step explanation:
The given points are M(-3, 5) and N(1, 8)
The formula for finding the slope, m, given the coordinates of two points on the line is given as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Where, (x₁, y₁) = (-3, 5), and (x₂, y₂) = (1, 8), we have;
[tex]Slope, \, m =\dfrac{8-5}{1-(-3)} = \dfrac{3}{4} = 0.75[/tex]
The slope, m = 0.75
The slope of the line that passes through the points M(-3, 5) and N(1, 8) in decimal form = 0.75.
During the bake sale, Paayal and Parvathy sold 200 cookies. Paayal sold her cookies for 5 cents each, while Parvathy sold her cookies for 10 cents each. The total amount of money customers paid for cookies was $11.00. How many cookies did Paayal sell? How many cookies did Parvathy sell?
Answer:
Paayal sold 180 cookies and Parvathy sold 20 cookies.
Step-by-step explanation:
From the information given, you can write the following equations:
x+y=200 (1)
0.05x+0.10y=11 (2), where:
x is the amount of cookies that Paayal sold and y is the amount of cookies that Parvathy sold.
First, you can solve for x in (1):
x=200-y (3)
Now, you can replace (3) in (2):
0.05(200-y)+0.10y=11
10-0.05y+0.10y=11
0.05y=1
y=1/0.05
y=20
Finally, you can replace the value of y in (3) to find x:
x=200-y
x=200-20
x=180
According to this, the answer is that Paayal sold 180 cookies and Parvathy sold 20 cookies.
Two pounds of raw materials are needed to produce one product. The desired ending balance of raw materials is 10% of the of the next month's production needs. (Refer to your answer in Activity Sheet 05). The beginning inventory of raw materials is 4,000 pounds and raw material cost per unit is P 0.50/per pound.
Answer:
Purchases= production + desired ending inventory - beginning inventory
Step-by-step explanation:
Giving the following information:
Two pounds of raw materials are needed to produce one product.
The desired ending balance of raw materials is 10% of the next month's production needs.
The beginning inventory of raw materials is 4,000 pounds.
The raw material cost per unit is $0.50 per pound.
To calculate the direct material purchase required for a given month, we need the production for each month. I will provide the formula and a small example to guide an answer.
To calculate the purchase required, we need to use the following formula:
Purchases= production + desired ending inventory - beginning inventory
For example:
Production:
January= 5,000 units
February= 4,500 units
Direct material purchases January:
Production= 5,000*2= 10,000
Desired ending inventory= (4,500*2)*0.1= 900
Beginning inventory= (4,000)
Total purchase in pounds= 6,900
Total direct material cost= 6,900*0.5= $3,450
is 10/2 an irrational number?
Answer:
yes it is because it is expressed in the form of a p/q
Step-by-step explanation:
If a number is expressed in the form of p/q then it is a rational number. Here p and q are integers, and q is not equal to 0. A rational number should have a numerator and denominator. Examples: 10/2, 30/3, 100/5.
so yes 10/2 is a rational number
oh and i mean yes its rational no its not irrational :)
No, it is not an irrational number.
Irrational numbers are those who cannot be turned into a fraction.
10/2 is a fraction. Therefore, it is a Rational number.
[tex]Edit:\;Also,\;if\;you\;were\;to\;make\;it\;a\;whole\;number\;then\;it\;would\;be\:5.[/tex] [tex]Which\;can\:be\;turned\;into\;5/1.[/tex]
To do so, divide the numerator (Top number) by the denominator (Bottom number).
